Problems solved by technology

With this structure, the lubricant path is isolated into two oil paths, the gear lubricating part and the wave generator part, and the path from the lubricant supply in the flexspline cavity to the gear is blocked. Once the lubricant in the gear space is used up, It will increase the friction of the gear and reduce the life of the gear

Abstract

The invention discloses a self-lubricating harmonic reducer. The self-lubricating harmonic reducer comprises a wave generator, a rigid gear and a flexible gear, wherein the rigid gear is meshed with the flexible gear; the wave generator is in contact with the inner wall of the flexible gear; an oil seal is arranged on an input shaft of the wave generator or an output end of the reducer in a sealing manner; a lubricant cavity is formed among the oil sea, the wave generator and the flexible gear; the oil seal comprises a ring-shaped base part; an elastic lip edge overhangs outwards from the outer side wall of the base part; the elastic lip edge is slantly arranged toward the wave generator; the overhanging tail end of the elastic lip edge tightly presses against the inner wall of the flexible gear. According to the reducer disclosed in the invention, the lubricant cavity, rather than the whole cavity in the flexible gear, is filled with the lubricant, so that the weight of the lubricant is decreased; the lubricating supply for the rigid gear and the flexible gear can be completed, and the flowing direction of the lubricant is not influenced by the mounting direction of the harmonic reducer, so that the favorable lubrication for the rigid gear and the flexible gear is ensured, the torn-up scrap iron of the rigid gear and the flexible gear is prevented from flowing back to the flexible bearing along with the lubricant, and the service life of the reducer is prolonged.

Description

technical field [0001] The present application generally relates to the technical field of harmonic reducers, and in particular, to an automatic lubricating harmonic reducer. Background technique [0002] Harmonic reducers are widely used in electronics, aerospace and aviation due to their high bearing capacity, large transmission ratio, small size, light weight, high transmission efficiency, long life, smooth transmission, no impact, no noise, and high motion accuracy. , Robotics and other industries. For example, the harmonic reducer is used in the transmission device of the robot. During the use of the robot, it will face various posture requirements. However, the lubricant is affected by gravity. When the use posture is that the wave generator is facing upward, the lubricant It is difficult to supply from the flex wheel gear cavity to the rigid wheel and the flex wheel, which causes insufficient lubrication between the rigid wheel and the flex wheel, increases the frict...
