Description of reference numerals: coil support, 7-rubber blanket, the outer coil support of 8-, 9-wedge-like boss in 1-cover plate, 2-slide block, 3-pin, 4-spring, 5-cushion block, 6-.
Detailed description of the invention
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1 and 2, the utility model mainly comprises interior coil support 6 and outer coil support 8, and outer coil support 8 centers, upper surface are provided with inner chamber, are provided with interior coil support 6 in the inner chamber of outer coil support 8, between interior coil support 6 bottoms and outer coil support 8, be provided with rubber blanket 7, rubber blanket 7 can axial deformation.
The center, upper surface of interior coil support 6 is provided with inner chamber, is provided with cushion block 5 in the inner chamber of interior coil support 6, and cushion block 5 is for supporting to clutch reduction gear ring lower surface.The upper surface of interior coil support 6 is along the circumferential direction evenly provided with multiple slide block slots, and a slide block 2 that can radially slide along interior coil support 6 is installed in each slide block slot.Each slide block slot lower end is provided with a rectangular spring groove, is provided with a spring 4 in each spring groove.In embodiment as shown in Figure 1, slide block slot is four.
Each slide block 2 lower surfaces are provided with a pin 3, one end of the spring 4 in pin 3 contact spring grooves, and the other end of spring 4 is pressed in to the medial surface of spring groove.
Described slide block 2 lateral surfaces are circular arc inclined-plane, and circular arc inclined-plane along slide block 2 from top to bottom gradually in receive, the surface that outer coil support 8 contacts with slide block 2 is provided with the circular arc inclined-plane matching with the circular arc inclined-plane of slide block 2.
