![]() Safety clutch
专利摘要:
The invention relates to a torque limiting clutch consisting of a locking member clutch 1 and a free-wheeling clutch 3. The locking member clutch 1 comprises first locking members 4 which engage recesses 6 in the clutch sleeve 7. The locking members 4 are radially movably arranged in bores of the clutch hub and pretensioned by springs 14. After leaving the recesses 6, the cams 5 are prevented from swinging backwards by means of a tilting wedge 8 arranged in a receiving recess 20 of the clutch hub 3 and by supporting itself against the torque transmitting direction with its supporting face 12 on the supporting face 9 associated with a recess 10 in the clutch sleeve 7. In this way, the cams 5 are prevented from swinging backwards and being damaged in the process. 公开号:SU1671165A3 申请号:SU884355634 申请日:1988-05-12 公开日:1991-08-15 发明作者:Кемпф Клаус 申请人:Жан Вальтершайд Гмбх (Фирма); IPC主号:
专利说明:
The invention relates to mechanical engineering, in particular to safety clutches, mainly for water driven by a tractor of agricultural machines or implements. The purpose of the invention is to increase the reliability Fig „1 shows the coupling, general view, partial sectional view of the main locking elements; in fig „2 - the same, partial section with the image of additional stop bodies; on fig.Z "- the coupling in the working position, the cross section; in fig „4 - the same, in the position of free stroke with The safety coupling contains two concentrically located half-couplings. One of the coupling halves is made in the form of a hub 1 with radial openings, and the other coupling half is in the form of a sleeve 2 with recesses 3 on the inner cylindrical surface. The coupling halves are interconnected by locking elements 4 with cams 5, the profile of which corresponds to the profile of the notches 3 bushings 2 о The locking elements 4 are installed with the possibility of displacement in the radial direction in the direction of the hub 1 and are spring-loaded by springs 6 through the supporting cams 7 towards the inner The surface of the hub 1, and their cams 5 are placed in the notches of the hub 2. This structure also contains elements of a free-wheeling clutch, the free-wheeling direction of which corresponds to the direction of torque transfer, made in the form of at least one additional locking element 8 placed in one of the coupling halves can be rotated. At the same time, at least one additional recess 9 is made on the inner cylindrical surface of the other half coupling, displaced in the circumferential direction from the “- auxiliary additional stop element 8” in the direction of rotation of the coupling. Each additional side porous element 8 is made in the form of a wedge radially wedge with one supporting surface. 10, and the additional recess 9 is provided with a counter support surface 11, located with an offset in the circumferential direction relative to 15 20 - 6711654 retaining surface 10 of additional locking element 8 " The main locking elements 4 can be placed in the sleeves 12, fixedly mounted in the holes of the hub 1. The springs 6 and the supporting elements 7 are installed in diametrically through The JQ of the hub aperture is perpendicular to the locking elements 4, and inside the springs there is a fastening bolt 13, on the skins of which the supporting disks are screwed. ki 14, The springs 6 are in one end contact with the supporting cams 7, and with the other with the supporting disks 14. The required compression of the springs 6 is provided by means of the disks 14, and then the disks 14 are fixed with the pin. The supporting cams 7 tighten the stop cams with their oblique surfaces. elements in radial on "- board 25 In the working position, the cams 5 hundred “- of the faulty elements 4 are in the“ hook ”with the sleeve 20. The torque is transmitted from one coupling half to the other through the locking elements 4" When In case of overloading of the coupling, the cams 5 of the locking elements 4 come out of the engagement with the sleeve 2, the locking elements 4 at the same time move radially inwards, pushing the supporting cams 7 apart and compressing the spring 6 "The clutch switches to a free wheeling mode. Under the action of the springs 6, the locking elements 4 tend to fall into the following recesses 3 on the surface of the sleeve 2, since 40 agricultural drives, in which safety couplings of this type are used, circumferential oscillations take place; in case of overload, a reverse relative ne 45 movement in the circumferential direction of the coupling halves occurs. The cams 5 of the locking elements “- cops 4, during the reverse course, tend to get into the recesses 3 again, which is highly undesirable. 35 When the hub 1 is rocking and moving clockwise (FIG. 4), the additional locking element 8 falls into the additional recess 9 of the sleeve 2 and, resting its support surface 10 on the support surface 11 of the recess 9, prevents further relative reverse movement of the coupling halves. 1 eleven Editor N.Kishtulinets Tehred L.

Claims (2) [1] Claim 1. A safety clutch containing two concentrically located half-couplings, one of which is made in the form of a hub with radial holes, and the other <- in the form of a sleeve with recesses on the inner cylindrical surface, interconnected by stop elements with cams, the profile of which corresponds to the profile recesses of the sleeve, while the locking elements are mounted with the possibility of moving in the radial direction in the holes of the hub and spring-loaded by springs to the inner surface of the sleeve, and their cams are placed in - sleeve bushings, characterized in that, in order to increase reliability, it is equipped with freewheel clutch elements, the freewheel of which corresponds to the direction of torque transmission, made in the form of at least 5 of one additional locking element rotatably disposed in one of the coupling halves, while at least one additional recess is made on the inner cylindrical surface of the other half coupling, offset in a circumferential direction relative to the additional locking element in the direction of rotation of the coupling. 15 2 "The coupling according to claim 1, I distinguish it by the fact that each additional locking element is made in the form of a wedge rotatable in the radial direction with one supporting surface— [2] 2θ, and the additional recess is made with a mating support surface located offset in the circumferential direction relative to the supporting surface of the additional 25 of the locking element '' FIG. 1
