Axial locking mechanism of rolling thrust bearing of vertical motor

Abstract

The invention discloses an axial locking mechanism of a rolling thrust bearing of a vertical motor. The axial locking mechanism comprises a stop step, a stop gasket and a locking nut; the axial locking mechanism is characterized in that a stop ring groove is formed in a motor rotating shaft which is rotationally arranged at one side of the locking nut and is arranged on the end surface of the rolling thrust bearing; two semicircular stop rings of which the cross sections are rectangular are clamped in the stop ring grooves; a locating ring which is provided with an inner step is arranged on the motor rotating shaft in a sleeving way and enables the stop rings to be arranged in the inner step in a sleeving way, and the stop gasket is arranged at the upper part of the locating ring in the sleeving way and is fastened by adopting the locking nut. The axial locking mechanism of the rolling thrust bearing of the vertical motor, disclosed by the invention, has the beneficial effects and the technical effects that the axial bearing capacity of the locking mechanism of the rolling thrust bearing can be effectively increased, a motor rotor and the motor rotating shaft are enabled not to loose or fall off under the action of a large axial force, in addition, the structure is simple, the cost is lower, and the performance is reliable.

Description

technical field [0001] The invention relates to an axial locking technology of a rolling thrust bearing of a vertical motor, in particular to an axial locking mechanism of a rolling thrust bearing of a vertical motor. Background technique [0002] The prior art vertical motor rolling thrust bearing axial locking mechanism usually adopts a stop step, a stop washer and a lock nut to fix it on the rotating shaft. In order to prevent the rolling thrust bearing from being polluted, a bearing inner cover and a bearing outer cover are respectively arranged on both sides of the rolling thrust bearing. During specific installation, a stop step is set on the rotating shaft of the motor, the rolling thrust bearing is set on the rotating shaft, close to the stop step, and then the stop washer is put on and fastened with a lock nut, and then, on the rolling thrust bearing Install the upper bearing inner cover and the bearing outer cover respectively on both sides. However, during the o...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the axial locking mechanism of the rolling thrust bearing of the vertical motor in the prior art cannot withstand a large axial force, which may cause the lock nut to fail, make the motor rotor and the rotating shaft loose or fall off, and cause accidents and other problems , the present invention proposes a vertical motor rolling thrust bearing axial locking mechanism
