Abstract
The utility model provides a motor end cover. The motor end cover comprises an end cover body and a bearing chamber arranged in an inner bottom part of the end cover body, a flexible bearing sleeve is arranged inside the bearing chamber, and an outer wall of the bearing sleeve is in interference fit with an inner wall of the bearing chamber. While assembling a bearing, the bearing can be directly placed in the bearing sleeve, and the bearing and the bearing sleeve are also in interference fit with each other, thus preventing the bearing from loosening and slipping in the bearing chamber. By adopting the structure, metal machining needn't be performed on the end cover again, assembling procedures are less, and the assembling is simple.
Description
Technical field:
The utility model relates to technical field of motors, specifically is a kind of electric motor end cap.
Background technology:
Be provided with bearing chamber in the electric motor end cap, when assembling, motor is used for placing bearing, in order to prevent bearing loosening skidding in bearing chamber, to closely cooperate between General Requirements bearing and the bearing chamber, and in the prior art, the producer of bearing and the producer of end cap generally are not same producers, if therefore need to closely cooperate between the two, before assembling, bearing chamber often needs the bearing chamber of end cap is carried out again metalworking, and needs machining accuracy higher, so that can closely cooperate with end cap, operation is more, assembles cumbersome.
The utility model content:
The purpose of this utility model is, overcomes existing technological deficiency, provides a kind of assembly process less, assembles simple electric motor end cap.
The technical scheme that the utility model provides is: the utility model provides a kind of electric motor end cap, it comprises end cap body and the bearing chamber that is located at the inner bottom part of end cap body, soft bearing holder (housing, cover) also is housed, the inwall interference fit of the outer wall of described bearing holder (housing, cover) and bearing chamber in the described bearing chamber.
Adopt said structure, the utlity model has following advantage:
The utility model also is provided with soft bearing holder (housing, cover) in the bearing chamber of electric motor end cap, the inwall interference fit of bearing holder (housing, cover) outer wall and bearing chamber, when running in bearings, can directly bearing be placed in the bearing holder (housing, cover), also adopt interference fit between bearing and the bearing holder (housing, cover), so just can prevent bearing loosening skidding in bearing chamber.Adopt this structure, no longer need end cap is carried out again metalworking, assembly process is less, and assembling is simple.
As preferably, described bearing holder (housing, cover) is the bearing holder (housing, cover) that elastomeric material is made.Adopt this material, comparision of production is convenient, and effect is better.
Description of drawings:
Accompanying drawing is the structural representation of the utility model permanent magnet rotor;
As shown in the figure: 1, end cap body, 2, bearing chamber, 3, bearing holder (housing, cover).
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
As shown in the figure: the utility model provides a kind of electric motor end cap, the bearing chamber 2 that it comprises end cap body 1 and is located at the inner bottom part of end cap body 1, soft bearing holder (housing, cover) 3 also is housed, the inwall interference fit of the outer wall of described bearing holder (housing, cover) 3 and bearing chamber 2 in the described bearing chamber 2.Bearing assemble is in bearing chamber 2 time, the inwall of bearing holder (housing, cover) 3 also with the bearing interference fit.
As preferably, the bearing holder (housing, cover) 3 that described bearing holder (housing, cover) 3 is made for elastomeric material.Adopt this material, comparision of production is convenient, and effect is better.
