Groove.
By using above-mentioned technical proposal, coordinated by locating piece and locating slot, circumferential fixation carried out to elastic washer,
So that after elastic washer is fixed, circumferential rotation is not susceptible to；While by setting more positioning strips, multiple locating slots are formed,
Locating piece can be easy to be caught in locating slot.
The utility model is further arranged to：Buffering ring, the buffering ring footpath are embedded with the middle part of the accommodating groove sidewall
There is the buffer stopper of some quality of rubber materials to extending internally.
By using above-mentioned technical proposal, buffer stopper can play slow when rotor is installed in stop bearing to a certain degree
The effect of punching；Because buffer stopper is quality of rubber materials, after bearing is arranged on storage tank, buffer stopper bending is caught in bearing and storage tank
Between space in, radially fixed effect is served to bearing；In lifting motor running, the stabilization of position of bearings fixation
Property.
The utility model is further arranged to：The side of the buffer stopper towards rotor is provided with inclined guiding incline.
By using above-mentioned technical proposal, when bearing is arranged in storage tank, bearing enables to delay by spigot surface
Rush that block is more pliable, and the bending surplus for being capable of Promoting Layered Buffer block of spigot surface, the life-span of Promoting Layered Buffer block.
The utility model is further arranged to：The buffer stopper is circumferentially arranged some raised lines.
By using above-mentioned technical proposal, raised line can increase frictional force circumferential between buffer stopper and bearing, further
Improve the fixation to bearing.
In summary, the utility model has advantages below：
1st, elastic washer by after natural resiliency and compression between storage tank increased frictional force, play and bearing delayed
Punching, protective effect；
2nd, storage tank sets the buffer stopper of quality of rubber materials, and after bearing is installed on storage tank, buffer stopper bending is caught in bearing
In space between storage tank, radially fixed effect is served to bearing.
