Abstract

The invention relates to an automatic power type lubricant passage way system for the transmission of satellite gears, which mainly comprises a gear box body, a sun gear, a plurality of satellite gears, a satellite carrier, an outer lubricant pipeline and an inner lubricant pipeline, wherein the outer circle of the satellite carrier is provided with a big gear, the outer wall of the gear box body is provided with a mechanical pump, a lubricant inlet and a lubricant outlet of the mechanical pump are arranged on the outer lubricant pipe, a main shaft of the mechanical pump is sleeved with a small gear, the big gear is meshed with the small gear to drive the mechanical pump to pump lubricant in the gear box body out to supply for a lubricant inlet pipeline through the outer lubricant pipeline. The lubricant passage way system utilizes power generated by the rotation of the satellite carrier to drive the mechanical pump to work, saves the energy and reduces the consumption as well as lowers the cost because the mechanical pump pumps the lubricant in the gear box body out and led the lubricant into the inner lubricant pipeline in the gear box body through the outer lubricant pipeline to safely and durably supply the lubricant for a drive device without external power source, fully lubricates and cools all drive parts and meshing parts, and has little mechanism abrasion and long service life.

Description

technical field [0001] The invention relates to a mechanical lubricating oil circuit system of a planetary transmission mechanism, in particular to a self-powered lubricating oil circuit system for planetary gear transmission without an external power source and sufficient lubrication. Background technique [0002] The internal lubrication of the planetary gear transmission mechanism is an important issue that affects the performance of the motor and the transmission device. The traditional planetary gear transmission mechanism uses an independent electric pump, such as a reducer oil supply lubrication and cooling device disclosed in Patent No. 02269310.6. The lubricating oil is pumped to the top of the reducer through the oil pump of the lubricating oil station on the external oil pipeline, and the lubricating oil splashes, Inject down into the internal bearings and gear meshing points of the reducer for lubrication, and finally return to the bottom of the reducer. The disa...
