Abstract

The utility model discloses a novel motor end cover, which comprises an end cover body (1) and a bearing seat (2) protruding from the middle of the inner end face of the end cover body (1), wherein the bearing seat (2) is provided with a bearing chamber (21) for mounting a bearing (3); a plurality of grooves (22) are formed on the inner wall of the bearing seat (2); the grooves (22) are communicated with the bearing chamber (21); a plurality of cylinder bodies (4) are embedded into the grooves (2); and the cylinder bodies (4) are partially extruded into the bearing chamber (21) via a clearance (23) and adhered to the outer lateral surface of the bearing (3) tightly. The novel motor end cover has simple structure, effectively reduces the displacement between the bearing and the bearing seat, reduces noise and vibration, and ensures the motor to work normally.

Description

A kind of New-type electric machine end cap

Technical field:

The utility model relates to a kind of New-type electric machine end cap.

Background technology:

Traditional ball bearing electric motor end cap, end-cover axle bearing are directly to contact with bearing, because the manufacturability of assembling; Cause bearing pedestal and bearing to have the gap between the two, when motor rotation, relative displacement can take place between the two in bearing and bearing pedestal; After the long-time running of motor, can cause carrier wear, thereby cause electric machine rotor to be close to; Motor noise is big, vibration is big, and then causes machine operation to lose efficacy.

Summary of the invention:

The purpose of the utility model is to the technological deficiency that exists in the prior art, and a kind of New-type electric machine end cap is provided, and this is simple in structure, effectively reduces displacement between bearing and the bearing pedestal, reduces noise, reduces vibration, guarantees the motor operate as normal.

The purpose of the utility model is to be achieved through following technical scheme.

A kind of New-type electric machine end cap; Comprise end cap body and the bearing pedestal that protrudes from end cap body inner face middle part, bearing pedestal is provided with bearings mounted bearing chamber, and the inwall of bearing pedestal is offered some grooves; Groove is communicated with bearing chamber; Groove forms the slit with the bearing chamber place of connection, and some cylinders embed in the groove, and the cylinder part is expressed in the bearing chamber from the slit and is adjacent to the lateral surface of bearing.

Above-mentioned described some cylinders connect through an annular ring, and annular ring is arranged on the end of cylinder.

Above-mentioned described cylinder is cylindrical.

Above-mentioned described some cylinders are 1 or more than 1, are distributed on the annular ring bottom surface.

Above-mentioned described cylinder and annular ring are integrated, and the material of processing of cylinder and annular ring is a rubber.

Above-mentioned described end cap body and bearing pedestal are cast aluminium formings.

The beneficial effect of the utility model is: 1) inwall of the utility model bearing pedestal is offered some grooves, and groove is communicated with bearing chamber, and some cylinders embed in the groove; The cylinder part is expressed in the bearing chamber from the slit and is adjacent to the lateral surface of bearing; Simple in structure, effectively reduce displacement between bearing and the bearing pedestal, reduce noise; Reduce vibration, guarantee the motor operate as normal; 2) some cylinders connect through an annular ring, and annular ring is arranged on the end of cylinder, and is easy for installation, and installation effectiveness is high; 3) cylinder and annular ring are integrated, and the material of processing of cylinder and annular ring is a rubber, and is with low cost; 4) end cap body and bearing pedestal are the one cast aluminium formings, are suitable for to produce in batches.
