1435215 Semi-rotary hydraulic actuators MITSUBISHI KINZOKU KK 19 Oct 1973 [21 Oct 1972] 48825/73 Heading G3P An hydraulic semi-rotary actuator comprises a housing 1 in which is rotatably mounted an output shaft 2 integrally formed with a rotor 7 having vanes 7A, 7B which together with abutments 6A, 6B of the housing define working chambers 30-33 inclusive, an input shaft 3 rotatably and coaxially located within an axial bore 12 formed in the output shaft 2 and a valve 50 which closes prior to a valve 8 to prevent the vanes contacting the abutments 6A, 6B. Valve 8 is formed by a pair of arcuate grooves 9A, 9B which are in the surface of the bore 12 and respectively communicate with pairs of working chambers 30, 32 and 31, 33 and co-operating grooves 11A, 11B in the surface of the input shaft 3 which are connected to axial ducts 14, 13 respectively. The valve 50 comprises grooves 19, 20 which are located in the outer surface of the output shaft 2 so as to communicate with a fluid supply bore 15 and discharge bore 16 and which are connected respectively to radial bores 21, 22 in the output shaft 2 and co-operating grooves 23, 24 in the surface of the input shaft 3 and in which ducts 13 and 14 terminate.

专利说明:

The invention relates to a MaiiiHHO structure, in particular to the hydraulic lines of the machines, and can be used to drive the working bodies that make a pivoting movement. A hydraulic rotary servo line is known, comprising a hollow cylindrical body closed at the ends with lids and having on the inner surface at least one radially protruding inward partitioning wall mounted inside the body of an inlet va passing concentrically through the first lid and a driving rotor mounted in the case the possibility of rotation on the input shaft and having at least one separating blade protruding on the rifle, forming working planes with the partition wall of the body, second shaft extending through and outwardly-axial second lid servo valve mechanism formed by mating surfaces of the Nogo input shaft and rotor, and inlet and outlet ducts communicated with Ser voklapannym mechanism and the openings for supplying fluid through the control valve f. A disadvantage of the known devices is the low reliability due to the possible impact of the blade into the partition with a sharp turn of the input shaft. The purpose of the invention is to increase reliability by preventing the impact of the blade and the septum. This goal is achieved by the fact that in a hydraulic rotary sulfur conduit comprising a hollow cylindrical body closed from the ends of the lids and having on the inner surface at least one radially protruding inward dividing wall mounted inside the housing the input shaft passing concentrically through the first lid, and a drive rotor mounted in the housing with the possibility of rotation on the input shaft and having at least one outwardly protruding dividing blade forming with a partition the working cavities, the output shaft protruding axially out through the second lid, the servo valve mechanism formed by the mating surfaces of the input shaft and the rotor, as well as the input and output channels communicated with the servo valve mechanism and the holes for supplying fluid through the control valve, the rotor is provided with an axial clutch covering the INPUT shaft, and the control valve is formed by two arc-shaped grooves formed on the outer surface of the clutch, connected to the inlet and outlet channels and openings supplying the liquid inserted in the first cover of the housing, the central angle of each arc-shaped groove being less than the maximum central angle of each working cavity. In addition, the arcuate grooves are narrowed at the ends. In Fig. 1 shows a hydraulic rotary servo, longitudinal section; FIG. 2 is a section A-A in FIG. one; in fig. 3 - rotor in neutral position, end view; “And FIG. 4 - control valve in the neutral position of the rotor; Fig. 5, rotor in the extreme right position, end view; in fig. 6 - control valve in the rightmost position of the rotor; in fig. 7 — rotor in the extreme left position, end view; in fig. 8 - control valve in the leftmost position of the rotor; in fig. 9 — node I in FIG. 6; The hydraulic rotary servo-conductor comprises a hollow cylindrical body 1, closed from the ends by covers 2 and 3 and having two radial inwardly protruding partition walls 5 on the inner surface 4. Inside the housing 1 there is an input shaft 6 passing concentrically through the cover 2, and the drive rotor 7 mounted in the housing 1 rotatably on the input shaft 6, the rotor 7 has two protruding outwardly separating blades 8, which form working cavities 9-12 with the partitions 5 of the housing 1, the protrusion a1;: sially outward through the cover 3. The surface 14 of the input shaft 6 and the surface 15 of the rotor 7 form a servo valve mechanism 16 having grooves 17 and 18. Fluid to the servo valve mechanism is supplied through the input channel 19 and the output channel 20 from the holes 21 and 22 dl. fluid supply. The channels 19 and 20 are connected to the openings 21 and 22 through a control valve 23 formed by two arcuate grooves 24 formed on the outer surface 25 of the rotor sleeve 26 26 spanning the input shaft 6. The grooves 24 are directly communicated with the openings 21 to 22 to the grooves 27.28 and the holes 29/30 are with channels 19 and 20. The holes 21 and 22 are made in the lid 2. The central angle of the arcuate grooves 24 is smaller than the maximum central angle of each of the working cavities 9.-12, and the grooves 24 themselves are narrowed at the ends. The proposed servo is as follows. When turning the input shaft 6, for example, to the right, clockwise, the fluid from the hole 21 through
the control valve 23, namely, through the arcuate groove 24, the orifice 29 and the groove 27, enters the inlet channel, then through the servo valve mechanism 16 into the working cavities 11, forcing the rotor to rotate in the same direction, following the rotation of the input shaft 6. Extruded from working cavities 10 and 12 fluid through the servo valve. The mechanism enters the output channel 20. Next, the fluid through the groove 28, the hole 30 and the groove 24 of the valve 23 enters the “hole 21 to drain.
When turning the input shaft 6 to the left, counterclockwise, the output shaft 13 of the rotor 7- tracks its rotation in the same way.
If, when the input shaft rises to the right or left until the stop, the rotor 7 rotates so that the grooves 24 of the coupling 26 come out of engagement with the holes 21 and 22, then the rotation of the rotor 7 will stop.
Making the central angle of the groove 24 less than the maximum working angle of each of the working cavities 9 - 12, eliminates the interaction of the blades 8 and the partition 5 in the extreme position of the rotor, which increases the reliability of the drive.
five
The implementation of the grooves 24 tapering provides a smooth braking of the rotor 7 at the end of the course.
