Monorail crane speed reducer lubricated through positive and negative rotation

Abstract

The invention discloses a monorail crane speed reducer lubricated through positive and negative rotation, which belongs to the technical field of lubrication of speed reducers. The invention provides a monorail crane speed reducer lubricated through positive and negative rotation, which is simple in structure and has a good lubricating effect. According to the adopted technical scheme, the bottom of a low-speed output shaft is sleeved on the upper part of a first gear shaft, and a bidirectional vane wheel is arranged between the low-speed output shaft and the first gear shaft; an upper end bearing is arranged between the low-speed output shaft and a shaft outlet cover; an oil path pipe is arranged inside the shaft body of the low-speed output shaft, and leads towards the upper side of the upper end bearing from a lower cabin of a box body; and the structure of the bidirectional vane wheel is as follows: the center of a vane wheel body is provided with a central through hole; a plurality of vane holes are uniformly formed around the central through hole; and a vane is arranged at the bottom of each vane hole through a vane shaft. According to the monorail crane speed reducer, during multi-stage gear transmission, lubricating oil enters the oil path pipe from the insides of the vane holes of the bidirectional vane wheel, and flows towards the upper side of the upper end bearing to lubricate the upper end bearing and a bearing below the upper end bearing.

Description

technical field [0001] The invention discloses a forward and reverse lubricable monorail crane reducer, which belongs to the technical field of reducer lubrication, and in particular relates to the lubrication of bearings of a monorail crane drive reducer. Background technique [0002] Because the low-speed shaft of the current monorail crane drive reducer used in coal mines protrudes vertically upwards, the two main bearings on the top cannot be lubricated. Generally, these two bearings are lubricated by injecting grease, which is very ineffective. There are also oil cups to lubricate the bearings. However, due to the influence of the structure, the height of the oil cup cannot be too high, so it still cannot reach the top of the lubrication. The role of the two bearings, so the bearings are often burned during work, and the service life is low. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art, and the technical problem...
