Oil bath type lubricating device for motor with large axial load

Abstract

An oil bath lubrication device for an axial big load carrying motor comprises a thrust bearing, a steady bearing, a bearing inner cap, and an end closure. The device is characterized in that the end closure is a larger aspect ration end closure and the thrust bearing is a spherical roller thrust bearing; wherein a shaft washer of the spherical roller thrust bearing is arranged on a motor shaft and a housing washer of the spherical roller thrust bearing is arranged in a bearing block inside the large aspect ration end closure; the steady bearing is embedded in the large aspect ration end closure and is arranged on the shaft end of the motor shaft which is arranged on the lower part of the spherical roller thrust bearing; a bearing housing is formed between the spherical roller thrust bearing and the steady bearing; the bearing inner cap is above the spherical roller thrust bearing and is arranged on the upper part of the large aspect ration end closure; an oil chamber is formed betweenthe bearing inner cap and the large aspect ration end closure and is internally provided with liquid lubricant; and the bearing block between the bearing housing and the oil chamber is provided with a plurality of oil passage through holes.

Description

1. Technical field [0001] The invention relates to an oil-bath lubricating device for a motor, in particular to an oil-bath lubricating device for a motor with a large axial load. 2. Background technology [0002] During the operation of the motor with large axial load, it needs to rely on the conversion of the lubrication device to achieve the conversion of the active force, so as to ensure the normal and stable operation of the motor. At present, the general lubricating device is generally composed of ordinary thrust bearings, bearing inner covers, end covers, and bearing outer covers (such as figure 1 shown). The lubricating device with this structure has the following defects: when the motor is running at full load, the thrust bearing will generate friction and heat due to the large axial force, and the heat will be very large. The bearing chamber is small, and the lubricant with poor fluidity cannot dissipate heat and lubricate the thrust bearing quickly and timely, s...

AI Technical Summary

Problems solved by technology

The lubricating device with this structure has the following defects: when the motor is running at full load, the thrust bearing will generate friction and heat due to the large axial force, and the heat will be very large. The bearing chamber is small, and the lubricant with poor fluidity cannot dissipate heat and lubricate the thrust bearing quickly and timely, so that the thrust bearing is heated for a long time, and eventually the thrust bearing is damaged due to overheating, thus greatly reducing the service life of the thrust bearing

Due to the particularity of the load of the motor with large axial load, it is not allowed to replace the thrust bearing frequently, so that the long-term stable operation of the motor cannot be guaranteed.
