Abstract

The invention discloses a lubricating grease injection tool for a bearing. The lubricating grease injection tool comprises a base plate, a pressing plate, a boss, a guide ring, a screw, a nut, grease nipple fixing devices, a grease nipple and a handle. A plurality of oil seepage holes are formed in the base plate, the pressing plate is arranged above the base plate, the boss is arranged on the base plate, the boss is sleeved with the guide ring and the guide ring abuts against the base plate. The screw is arranged vertically upwards in the center of the bottom of the base plate, the screw penetrates through the boss and the pressing plate, the nut is arranged on the screw, the nut is located between the boss and the pressing plate, a groove which can contain the nut is formed in the bottom of the pressing plate, the grease nipple fixing devices are arranged on the pressing plate, the grease nipple is fixedly arranged on one grease nipple fixing device, the handle is connected with the outer portion of the screw in a threaded mode, and the handle is located above the pressing plate. The lubricating grease injection tool for the bearing has the advantages that convenience is brought to lubricating grease injection of the bearing, complete lubrication of the bearing can be guaranteed, and the usability of the bearing is guaranteed.

Description

technical field [0001] The present invention relates to a tool, in particular to a bearing grease injection tool for traction motors used in subways. Background technique [0002] Bearings are very critical precision components in traction motors used in subways, and have a great impact on the performance of traction motors. It separates the stationary stator and the rotating rotor, guiding the rotation of the shaft and reducing friction. The quality of bearing lubrication will directly affect the performance of the bearing. Bearings of traction motors are required to be fully lubricated. In the past, the grease injection method for bearings was to inject grease directly into the bearing clearance, which could not guarantee complete lubrication of the bearings, which affected the performance of the bearings. SUMMARY OF THE INVENTION [0003] In view of the above existing technical problems, the purpose of the present invention is to provide a bearing grease injection too...
