Pulling motor for locomotive

Abstract

The invention relates to a motor and especially a lubricating structure of a bearing of the driving end of the motor, in particular to a traction motor for an engine. The traction motor of the invention solves the problem that the driving end of the traction motor for the engine easily generates the oil leakage phenomenon and consequently affects the lubrication effect, and the defects and problems existed in the grease lubrication of the bearing at the driving end. In the traction motor for the engine, an oiling case is positioned at an external bearing cover, a through hole communicated with a bearing house is positioned on the part of the external bearing cover which is in the oiling case, a plug is sealed in the through hole, and the plug is penetrated with a cotton thread; a oil leakage hole is positioned at the lower part of each radial sealing groove on the internal part of an internal bearing cover, the lower part of the internal bearing cover is equipped with an oil return hole, and the end cover and the external bearing cover are equipped with a mutual communicated oil return hole respectively. The invention can not only achieve the oil lubrication on the bearing, but also not cause the oil leakage problem. Good oil circulation is formed between the bearing house and the gear box. The invention can be applied on all traction motor for the engine which is lubricated with oil and other motors which are lubricated with oil.

Description

technical field [0001] The invention relates to a motor, in particular to a lubricating structure for a bearing at the drive end of the motor, in particular to a traction motor for a locomotive. Background technique [0002] The traditional lubrication system of traction motors for locomotives uses grease lubrication for the bearings. The motor transmission end is provided with a gear box 21, and the pinion 22 of the motor transmission end and the locomotive gear 23 are meshed in the gear box 21 and lubricated with oil, such as figure 1 shown. There are certain defects in this structure during operation: 1. Structural limitations may lead to the phenomenon of "oil leakage" and cause motor failure: limited by the structure of the motor, the outer bearing cover 4 (non-rotating part) and the outer sealing ring fixed to the shaft There must be a certain gap between 24 (rotating parts), and the motor cannot be completely sealed with the gear box. When the motor rotor rotates, ...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a traction motor for locomotives in order to solve the defects and problems that the transmission end of the traction motor for locomotives is prone to "oil leakage" that affects the lubrication effect and the bearings at the transmission end use grease lubrication. The motor adopts a new design The motor bearing lubrication structure makes the motor bearing and gear lubricated with the same brand of oil, and effectively avoids the phenomenon of "oil leakage"
