Lubricant supply system

By installing a bracket, oil flow path, and oil dispersion section on the motor, the lubricant is dispersed by centrifugal force and air force, which solves the problem of uneven lubrication in traditional motor reducers, and achieves efficient lubricant supply and a reduction in pump specifications.

AI Technical Summary

Technical Problem

The reducer of a traditional off-shaft rotor motor cannot effectively supply lubricant to the bearing in the center part, and the lubricant supply pump in the existing technology requires high specifications and large size, making it difficult to achieve uniform lubrication by stirring.

Method used

A lubricant supply system was designed, including a bracket, an oil flow path, an oil dispersion section, and an oil distributor. It utilizes centrifugal force and wind force to evenly disperse the lubricant into the needle roller bearing and the bracket bearing during high-speed rotation, thereby reducing the need for forced lubrication of the pump.

Benefits of technology

It achieves uniform lubrication of all parts of the reducer during high-speed rotation, reduces the required specifications and size of the lubricant pump, and improves lubrication efficiency.

Abstract

The present disclosure relates to a lubricant supply system, and more particularly, to a lubricant supply system applied to a motor of a vehicle. According to the lubricant supply system of the present disclosure, by including a flow path that supplies lubricant to a shaft, an oil spreader coupled to the shaft, and a bracket that receives oil dispersed from the oil spreader, and inserting a pin that stores and supplies lubricant into the bracket, compared to the conventional, it is possible to minimize forced lubrication, and even during high-speed rotation, it is possible to smoothly supply oil to the needle bearing and the bracket bearing using centrifugal force and wind force naturally generated by the rotor on the shaft.
