Forced bearing lubrication structure for speed reducer

Abstract

The invention relates to a forced bearing lubrication structure for a speed reducer. The forced bearing lubrication structure comprises a box and a hollow shaft, the hollow shaft is rotatably arranged in the box, a first bearing is arranged outside the hollow shaft, a second bearing and a third bearing are arranged inside the hollow shaft, the hollow shaft is provided with a shaft shoulder, the second bearing and the third bearing are positioned on the inner side of the shaft shoulder of the hollow shaft, the first bearing is positioned at the upper end of the shaft shoulder of the hollow shaft, the shaft shoulder of the hollow shaft is provided with an oil inlet hole and is in sleeve connection with an oil inlet ring, the oil inlet hole is positioned on the inner side of the oil inlet ring, the oil inlet hole of the shaft shoulder is communicated with an inner cavity of the oil inlet ring, the inner cavity of the oil inlet ring is connected with an oil inlet pipe, and the oil inlet pipe penetrates the box and is connected with an external oil pump. When in assembly, additional regular disassembly and maintenance of the lubrication structure are omitted once installed, and the lubrication structure only needs to be maintained along with the speed reducer.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a forced lubrication structure for a bearing of a reducer. Background technique [0002] As we all know, mechanical operation needs to use oil or grease for lubrication, and the reducer is no exception. Some reducers cannot arrange a thin oil station on site and can only rely on self-lubrication. Due to the placement of the reducer and other reasons, some internal gears or Bearings cannot be adequately splash lubricated, so additional oil is required for lubrication. [0003] In the past, in the reducer, two bearings were arranged inside the hollow shaft and one bearing was arranged outside. The two bearings inside the hollow shaft did not come into contact with lubricating oil and could not be lubricated. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a forced lubrica...
