Problems solved by technology

However, for vertical motors, the bearings at the non-drive end of the motor need to withstand thrusts in both upward and downward directions at the same time, and the axial load requirements in these two directions are very strict. The requirements for sealing are also very high, and the existing conventional bearing structure can no longer meet the above requirements of vertical motors

Embodiment Construction

[0010] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0011] As shown in the figure: the bearing device of the DC vertical motor in the embodiment is mainly composed of a rotating shaft 1, a locking screw 2, a bearing outer cover 3, an oil throwing pan 4, a single row angular contact bearing 5, a bearing sleeve 6, and a bearing inner cover 7 And components such as labyrinth ring 8 are formed.

[0012] Such as figure 1 As shown, the two single-row angular contact bearings 5 ​​are arranged back-to-back to form a bearing set; the bearing sleeve 6 is supported and assembled on the rotating shaft 1 through the bearing set, the inner side of the bearing set is sealed and assembled with the bearing inner cover 7, and the outer side of the bearing set Seal the bearing cover 3. Since two single-row angular contact bearings 5 ​​arranged back-to-back are used to form the bearing group, the bearing device can withstand larg...

Abstract

The invention relates to a bearing device of a direct current vertical motor, which comprises a rotating shaft, a bearing outer cover, a bearing sleeve, a bearing group and a bearing inner cover; the bearing sleeve is supported and assembled on to the rotating shaft through the bearing group; the bearing inner cover is assembled on the inner side of the bearing group in a sealing way, and the bearing outer cover is assembled on the outer side of the bearing group in a sealing way. The bearing device of the direct current vertical motor is characterized in that: the bearing group mainly comprises two single row angular contact bearings which are arranged back to back. The bearing device of the direct current vertical motor has a simple and reasonable structure, good sealing performance, high reliability and low manufacturing cost, can bear quite large axial load in an upward direction and a downward direction when the safety and the reliability of the motor are ensured, has higher rigidity, can meet the use requirements of the vertical motor, and has an obvious effect.

Description

technical field [0001] The invention relates to a transmission part of a direct current vertical motor, in particular to a bearing device for a non-transmission end of a direct current vertical motor. Background technique [0002] Although the bearings of ordinary DC horizontal motors also need to bear radial and axial loads, the requirements for axial loads are not very high. However, for vertical motors, the bearings at the non-drive end of the motor need to withstand thrusts in both upward and downward directions at the same time, and the axial load requirements in these two directions are very strict. The sealing requirements are also very high, and the existing conventional bearing structure can no longer meet the above requirements of the vertical motor. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a bearing device for a direct current vertical motor with a simple and reasonable ...
