Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example 1:

referring to fig. 1, for the utility model discloses a shock attenuation low noise three-phase asynchronous machine, including casing 1 and the supporting legs 2 that is connected with casing 1, supporting legs 2 includes backup pad 22, buffering subassembly 3 and articulated slab 21, and articulated slab 21 one end and casing 1 lower half are articulated mutually, and the other end is articulated mutually with

buffering subassembly

3, and 3 levels of buffering subassembly set up in backup pad 22.

Referring to fig. 2, the buffering assembly 3 includes a buffering plate 31 and a buffering element, a buffering groove 221 is provided on the supporting plate 22, the buffering plate 31 and the buffering element are both located in the buffering groove 221, one end of the buffering element is connected to the buffering plate 31, the other end of the buffering element is connected to the supporting plate 22, one end of the buffering plate 31, which is far away from the buffering element, is further fixedly connected to a first ear plate 313 hinged to the hinge plate 21, the first ear plate 313 extends out of the buffering groove 221, a second ear plate 211, which is used for being hinged to the first ear plate 313, is provided on the hinge plate 21, a cover plate 23 is further connected to the supporting plate 22 through a bolt, the cover plate 23 covers the buffering groove 221, and a sliding groove 232, which is used for enabling the first ear plate 313 to penetrate out, is provided on the cover plate 23. The buffer member is a buffer spring 32, a catch plate 231 is further fixedly connected to the cover plate 23, and the catch plate 231 extends into a gap at one end, far away from the buffer plate 31, of the buffer spring 32. Therefore, the cover plate 23 can effectively prevent foreign materials from entering the buffer tank 221. The buffer plate 31 is provided with a hook 311, the hook 311 is detachably connected with the buffer plate 31, and the hook 311 is connected with the buffer spring 32. The hook 311 is an L-shaped plate, one end of which is connected to the buffer plate 31 by a bolt, and the other end of which extends into a gap between the buffer spring 32 and the end of the buffer plate 31, and a baffle 312 for preventing the buffer spring 32 from moving back and forth is fixedly connected to the hook 311. Therefore, when in maintenance, the cover plate 23 and the hook 311 are detached to repair and replace the buffer spring 32, so that the operation is simple.

Referring to fig. 2, in order to avoid the misalignment problem when the hooks 311 are mounted on the buffer plate 31, the buffer plate 31 is provided with mounting grooves 314, one ends of the hooks 311 are located in the mounting grooves 314, and the upper surfaces of the hooks are flush with the upper surface of the buffer plate 31.
