Abstract

The invention relates to a grease-lubrication soft-start planetary differential reducer for bearings. The reducer comprises a box body and an input bevel gear pair, a planetary transmission piece, a speed-up transmission piece and a brake piece which are arranged in the box body. A sealed bearing is used as the supporting structure of a solar wheel axle and a shaft gear in the box body. The structure of the sealed bearing is compact and the requirement on the axial dimensions of the sealed bearing is low, so that the reducer has the advantages of simpleness in the installing structure and convenience in installation and maintenance. The self-seal of the sealed bearing has good dust prevention and sealing effects. In addition, good operative condition can be maintained in the process of the operation of the bearing without the supply of lubricant, so that the maintenance cost is reduced. The reducer is applicable to equipment which has complicated structure, strict requirement on sealing, difficulty in maintenance and oil supply and inconvenience in adoption of an additional sealing device.

Description

technical field [0001] The invention relates to the technical field of transmission, and relates to a grease lubricated soft start planetary differential reduction device for bearings. Background technique [0002] Soft start technology is a modern advanced mechanical transmission technology. Its advanced feature is that it can make mechanical equipment start smoothly under heavy load conditions, so it is widely used in large-scale mining machinery and equipment, such as mine hoists and so on. [0003] "Destruction Causes and Treatment Methods of Mine Reducers" pointed out that: reducer failures account for about 40% of coal mine equipment failures. Under the condition of poor lubrication or impure lubricating oil, the poor lubrication will aggravate the wear degree of the bearing. At the same time, after the pollutants enter the interior of the bearing, the lubricating grease will gradually deteriorate, and indentations will be generated on the rolling contact surface, whic...
