Motor end cover and bearing assembling structure

Abstract

The invention discloses a motor end cover and bearing assembling structure, which comprises a motor rotating shaft, a bearing, a bearing outer cover and an end cover ring plate, wherein the bearing and the bearing outer cover are assembled on the motor rotating shaft on the inner side of the end cover ring plate, an inwards concave ring groove is formed in the inner side of the end cover ring plate, a hole for installing a shaft sleeve is formed in the bearing outer cover, one end of the shaft sleeve is installed in the ring groove, the other end of the shaft sleeve is assembled in the bearing outer cover through the hole, an oil path which is communicated with the internal part of the bearing outer cover is formed in the bearing sleeve, an oil pipe is connected onto the oil path, a ring notch is formed in the top of the outer side of the bearing outer cover and a plurality of oil outlets are formed in the bottom part of the ring notch. The motor end cover and bearing assembling structure has the advantages that since the bearing and the bearing outer cover are assembled in the end cover ring plate, the internal space of a motor base is fully utilized, the total length of a motor is shortened, the cost is reduced and the special demands of customers are met.

Description

technical field [0001] The invention relates to a motor, in particular to an assembly structure of a motor end cover and a bearing. Background technique [0002] At present, when customers customize the motor, they will have a requirement for the total length of the motor to adapt to the installation environment of the motor. When it is found that the total length of the motor is much smaller than the total length of our standard motor, many manufacturers are powerless, such as figure 1 structure shown, figure 1 It is a schematic diagram of a traditional motor end cover and bearing assembly structure. The traditional motor end cover and bearing assembly structure includes a motor shaft 10, a bearing 11 is mounted on the motor shaft 10, and a bearing outer cover 12 is installed outside the bearing 11. The bearing outer cover 12 is connected with an oil pipe 13 through an oil passage, and the bearing 11 and the bearing outer cover 12 of this assembly structure are set throug...

AI Technical Summary

Problems solved by technology

When it is found that the total length of the motor is much smaller than the total length of our standard motor, many manufacturers are helpless, such as figure 1 structure shown, figure 1 It is a schematic diagram of a traditional motor end cover and bearing assembly structure. The traditional motor end cover and bearing assembly structure includes a motor shaft 10, a bearing 11 is mounted on the motor shaft 10, and a bearing outer cover 12 is installed outside the bearing 11. The bearing outer cover 12 is connected with an oil pipe 13 through an oil passage, and the bearing 11 and the bearing outer cover 12 of this assembly structure are set through the motor end cover 14, that is, a part of the bearing 11 and the bearing outer cover 12 is located on the motor machine. The rest is located outside the motor frame, and the assembly of the integral bearing exceeds the motor end cover 14, occupying the external space of the motor frame, resulting in a long overall length of the motor, which cannot meet the customer's requirements
