    [6] Since the size of the counterweight arrangement is limited, there is a need for a possible adjustment of the mass of the counterweight arrangement without increasing the size of the counterweight arrangement relative to structures available today.
    [7] The present invention generally relates to a counterweight arrangement for use in a concrete. Generally, the counterweight arrangement rotates together with an eccentric about a fixed major axis in the concussion. The counterweight arrangement provides a balance for the offset rotation of the eccentric and the orbiting motion of the main body and the jacket.
    [8] The counterweight arrangement is mounted to rotate with the eccentric and includes a generally annular counterweight body. The counterweight body of the counterweight arrangement comprises, in one embodiment, both a weighted part and an unweighted part which are connected to each other in a generally annular shape during casting. But it should be understood that other counterweight arrangements can also be used.
    [9] The weighted part of the counterweight body comprises a number of individual tanks, each of which opens an open inner space. The individual tanks formed in the weighted part are separated from each other by vertical walls in such a way that the open inner spaces of the series of tanks can be filled separately if desired.
    [10] The counterweight arrangement comprises a first ballast located in at least one of the tanks formed in the weighted part of the counterweight body. The first ballast is formed of a first material with a first density. In an embodiment according to the invention, the first ballast is formed by a series of individual rods each comprising a tungsten alloy.
    [11] According to an embodiment of the invention, a second ballast is also placed in at least one of the tanks containing the first ballast in such a way that at least one of the many tanks comprises both the first and the second ballast. In an embodiment according to the invention, the second ballast is formed from a second material with a second density which is less than the first density. For example, the second density of which may be lead (Pb). According to another embodiment, the second balal stone is placed in each of the many tanks formed in the weighted part of the counterweight body.
    [12] Since the first ballast is formed of a material having a higher density than the second ballast, the combination of the first and the second ballast allows the counterweight arrangement to have a concentrated density at desired locations along the annular counterweight body of the counterweight arrangement. In an embodiment according to the invention, the second ballast is formed of lead which is poured into each desired tank. The molten lead solidifies around the first ballast in each desired tank containing both the first and second ballasts.
    [13] In a second embodiment according to the invention. is a cover part mounted over the many open tanks to close the tanks after the tanks have been filled with the first and the second ballast. In this way, the cover member encapsulates the open tanks comprising the first ballast and the second ballast to prevent the ballasts from being separated from the counterweight arrangement.
    [14] The drawings illustrate the best embodiment for carrying out the invention. The drawings show:
    [15] Figure 1 is a partially sectioned perspective view of a concussion comprising the counterweight arrangement according to the present invention;
    [16] Figure 2 is a perspective view of the eccentric and counterweight arrangement assembled according to the present invention;
    [17] Figure 3 is an exploded perspective view of the eccentric and counterweight arrangement showing the location of the ballasts within the counterweight arrangement;
    [18] Figure 4 is a perspective view of the counterweight arrangement assembled according to the present invention; and
    [19] Figure 5 is a section taken along line 5-5 of Figure 4.
    [20] Figure 1 shows a conical crusher 10 used to crush materials such as rock, rock, ore, minerals or other substances. The crusher 10 may be a rock crusher of any size or include any other type of crusher head. A base 14 rests on a platform-like foundation which may comprise concrete pillars (not shown), a foundation block, a platform or other supporting part. A central hub of the main frame 12 includes an upwardly diverging vertical bore or tapered bore 18.
    [21] The main shaft 20 carries an eccentric 22 which surrounds the main shaft 20 and is coupled to the main part 24. Eccentric 22 rotates about the stationary main shaft 20, and causes the main part 24 to orbit inside the concussion 10. The orbiting movement of the main part 24 inside a housing 26 attached to an adjusting ring 28 connected to the main frame 12 allows rock, stone, ore, minerals or other materials to be crushed between a jacket 30 and a housing liner 32. The main portion 24 includes a feed plate 33 which directs material toward a crushing gap 34 The housing liner 32 is arranged against the housing 26 and and the jacket 30 is arranged to the main part 24. The main part 24 forces the jacket 30 against the housing lining 32 to create the rock crushing force inside the crushing gap 34.
    [22] As shown in Figure 1, an eccentric bushing 36 is located between the stationary main shaft 20 and the rotating eccentric 22. The eccentric 22 and the eccentric bushing 36 rotate about the stationary main shaft 20 by interaction between a pinion 38 arranged on a drive shaft 40 and a gear 42 provided to the lower portion of the eccentric 22. A plurality of lubricating oil passes through the center of the stationary main shaft 20 to provide lubrication between the eccentric bushing 36 and the stationary main shaft 20.
    [23] A lower main bushing 44 is located between the outer surface of the eccentric 22 and the lower part of the main part 24. Lubricant is received between the lower main bushing 44 and the eccentric 22 for lubricating the contact area between the rotating eccentric 22 and the stationary main part 24.
    [24] As can be seen in Figure 1 when the concussion is in operation, the drive shaft 40 rotates the eccentric 22 by co-operation between the pinion 38 and the gear 42. Since the outer diameter of the eccentric 22 is offset from the inner diameter, the rotation of the eccentric 22 creates the orbiting motion of the main part inside the stationary housing 26. The circular movement of the main part 24 changes the size of the crushing gap 34, which allows the material to be crushed to enter the crushing gap. Additional rotation of the eccentric 22 creates the crushing force inside the crushing gap 34 to reduce the size of particles to be crushed in the crusher 10. The crusher can be one of many different types of crusher available from various suppliers, such as Metso Minerals in Milwaukee, Wisconsin. . For example, the crusher 10 shown in Figure 1 may be an HP® series rock crusher, such as the HP®400 available from Metso Minerals. But different types of concussions can be used within the inventive concept according to the present invention.
    [25] During operation of the crusher 10 and crushing of material, the crushing force formed in the crushing gap 34 exposes the jacket 30 of the main part 24 to a force. This force causes the main body 24 to surface around the pivot point formed by a hinge cup 46 and the hinge ball 4 of the main body. This pivoting movement causes the lower main bushing 44 to co-operate with the eccentric 22.
    [26] As shown in Figure 1, the eccentric 22 is coupled to a counterweight 48. The counterweight arrangement 48 is coupled to the eccentric 22 and rotates with the eccentric about the major axis 20.
    [27] Referring to Figure 2, there is shown an embodiment of the counterweight arrangement 48 according to the present invention. The counterweight arrangement 48 is coupled to the eccentric 22 with a generally horizontal flange 50. The flange 50 includes a series of connectors 52 which securely attach the counterweight arrangement 48 to the eccentric 22.
    [28] As shown in Figure 2, the counterweight arrangement 48 includes a counterweight body 60.
    [29] In the embodiment shown in Figure 2, the height of the outer wall 62 of the folded portion 64 extends over the surface 68 of the unfolded portion 66. A vertical wall 70 defines a transition between the unfolded portion 66 and the folded portion 64. .
    [30] In the weighted portion 64, the counterweight body 60 includes a series of open tanks 72 located adjacent to each other and extending along the circumference of the weighted portion 64. As shown in Figure 2, the tanks 72 extend over approximately half the length of the outer circumference. of the counterweight body 60.
    [31] Each tank 72 includes an open space 73 as defined by the outer wall 62 and an inner wall 74. The gap between the inner wall 74 and the outer wall 62 defines the radial width of each tank 72. The tanks 72 are separated from each other. with a vertical dividing wall 76. The two end tanks 72 are each defined at their outer ends by an end wall 78. As shown in Figure 5, each tank 72 is defined by its bottom by a bottom wall 80. As can be seen by Figures 2 and 5, they each tank 72 a generally enclosed hollow open space 73 which can accommodate material in a manner to be described in more detail below.
    [32] Referring back to Figure 2, each dividing wall 76 includes an enlarged receiving portion 82 with a central opening 84. The receiving portion 82 extends only a portion of the vertical height of the dividing wall 76, which can be seen in the figure.
    [33] Referring to Figure 3, according to the embodiment shown, one or two of the individual tanks 72 receive a first ballast 86. Figure 3 shows two separate ballasts 86a and 86b, although a different number of ballasts may be used, for example a or three. According to the embodiment shown in Figure 3, the first ballast 86 comprises a series of individual weights 88 positioned to form a first ballast. In the embodiment shown in Figure 3, the individual weights 88 are formed from a material different from the base material of the counterweight body, such as tungsten alloy rods connected to each other by an outer terminal 90 and a pair of inner terminals 92. It should be appreciated that other weights may have shapes other than rods or may be of uniform blocks or rods within the inventive concept of the present invention.
    [34] In the embodiment shown in Figure 3, the first ballast 86a comprises two rows of tungsten bars while the first ballast 86b comprises only a single row of tungsten bars. As will be described below, the number of individual weights 88 placed in one of the tanks 72 can be selected during the construction of the counterweight arrangement 48 to adjust the weighting of the counterweight arrangement 48 in the desired manner. In the embodiment shown in Figure 2, only two of the tanks 72 include the first ballast 86. However, it should be appreciated that any of the five tanks shown in Figure 2 may include the first ballast 86 depending on the specific design of the counterweight arrangement.
    [35] During the construction of the counterweight arrangement 48, the individual tanks 72 are filled with a first ballast 86 in the desired manner. As described in the embodiment according to Figures 2 and 3, only two of the five tanks 72 comprise a first ballast 86. In this embodiment, the first ballast is formed from a very dense material, such as tungsten alloy rods.
    [36] Referring to Figure 5, when the first ballast 86 has been placed in the tank 72, a second ballast 94 may be placed in the tank 72 to further increase the weight of the counterweight arrangement 48. In the embodiment shown in Figure 5, the second ballast 94 is formed. from a second material other than the first two materials and the base material of the counterweight body. In the embodiment shown, the second material is lead which is poured into the open tank 72 and surrounds the first ballast 86. Although lead is that shown in the embodiment according to Figure 5, it should be appreciated that other types of material may be used as a second ballast 94.
    [37] In one embodiment, after the first ballast 86 is placed inside the tank 72, molten lead is held into the recess 72 to enclose the first ballast 86. The molten lead forming the second ballast 94 solidifies and fills the open interior. 73 of the tank 72 shown. Referring to Figure 2, it should be noted that each of the five tanks 72 is filled with the second ballast 94 while only two of the tanks 72 contain the first ballast 86.
    [38] As described above, in one of the embodiments of the invention, the first ballast is formed by individual tungsten alloy rods having a density of about 17 grams per cubic centimeter. The second ballast, which in the described embodiment is formed of lead, has a density of approximately 11.34 grams per cubic centimeter. Although the tungsten material forming the first ballast 86 has a higher density, the cost and difficulty of processing tungsten alloy reduces the possibilities of using tungsten alloy as the only material inside any of the tanks 72. However, by using two different materials of different density inside the tanks 72 makes it possible to give the counterweight arrangement a more concentrated weight in desired areas.
    [39] Referring to Figure 3, when the first ballast 86 and the second ballast 94 have been placed in the tanks 72, a first cover member 96 is placed to the tanks to close each tank 72 formed in the weighted portion 64. The cover member 96 is a semi-rigid portion 96. circular plate with a series of openings 98 each receiving a connection 100. The connections 100 are each received in the openings 84 formed in the receiving part 82 formed as part of the partition wall 76, which is best seen in Figure 2.
    [40] In addition to the first cover member, a second cover member 102 is mounted to the unfolded portion 66. A series of spacers 104 are each positioned in line with a bore 106 formed in the outwardly facing surface 68. An elongate connection 108 extends through each opening 110 formed in the second cover portion 102 and extending through a central opening formed in one of the spacers 104. The threaded portion of the connection 108 is received in the bore 106 to hold the second cover portion 102 in line with the first cover portion 96, which can best be seen in Figure 4. An outer ring 112 is attached to an outer wall 62 to generally enclose the eccentric, which can best be seen in Figure 4.
    [41] As previously described, the first ballast 86 and the second ballast 94 are formed of various materials as previously described. The first ballast 86 in the described embodiment is formed of individual tungsten alloy rods while the second ballast 94 is formed of lead. However, it should be understood that other materials may be used within the scope of the inventive concept of the present invention. Most importantly, it should be understood that the first ballast 86 should be formed of a material having a higher density than the second ballast 94. The ratio of the first ballast 86 to the second ballast 94 may vary within the scope of the present invention.
    [42] Although specific dimensions are mentioned in the above described, it should be understood that these dimensions are for illustrative purposes only, and are not limiting with respect to the inventive concept. More specifically, the size and configuration of the first and second ballasts may vary, resulting in different weights of the counterweight arrangement 48.
    [43] This description uses examples to describe the invention, including the best mode of execution, and also to enable those skilled in the art to make and use the invention. The concept of invention is defined by the requirements, and may include examples which appear to those skilled in the art. Such examples are intended to be within the scope of the inventive concept of the claims if they include design details that do not differ from the wording of the claims, or if they contain equivalent design details that do not differ significantly from what is written in the claims.
