Cycloid steel ball planetary reducer gap elimination mechanism

Abstract

The invention discloses a cycloid steel ball planetary reducer interval removing mechanism. A cage is arranged out of an inner ring; a steel ball A is positioned in the cage; the external of the cage is sleeved with an outer ring; a rolling groove is formed in the outer side of the outer ring; a baffle plate is arranged at one end of the rolling groove in the outer side of the outer ring; rolling grooves are respectively formed in an inner ring of a mobile disc A and an inner ring of a mobile disc B; baffle plates are respectively arranged at one ends of the rolling grooves in the inner rings of the mobile disc A and the mobile disc B; the rolling groove in the outer side of the outer ring and the rolling grooves in the inner rings of the mobile disc A and the mobile disc B form a combined rolling groove; a steel ball B is arranged in the combined rolling groove; groove holes are formed in the inner sides of the mobile disc A and the mobile disc B; springs are respectively arranged in the groove holes; a thread hole is formed in the outer side of the mobile disc B; a through hole is formed in a retainer ring; and the retainer ring is fixed on the outer side of the mobile disc B through a screw. The cycloid steel ball planetary reducer interval removing mechanism is simple and compact in structure, adopts gapless transmission, and can continuously remove side intervals of engagement pair teeth; the discs axially move through the steel ball in the combined groove; and the steel ball and a chute are contacted in a rolling manner, so that the friction resistance is low, and the axial movement resistance of each disc is low.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a clearance elimination mechanism of a reducer. Background technique [0002] The reducer is an important part of the machinery industry, and its transmission performance directly affects the production efficiency, work performance and product quality of the machinery. After the modern high-precision transmission mechanism wears out, there will be backlash on the tooth side, and its transmission performance will inevitably decline. Only having a backlash-free meshing transmission for a while can no longer meet the requirements of the precision transmission mechanism for transmission accuracy. Cycloidal steel ball planetary reducer has a stage clearance elimination mechanism that cannot realize continuous elimination of tooth side clearance, and a stepless clearance elimination mechanism cannot achieve constant axial force output, and the axial movement of the plan...

Problems solved by technology

After the modern high-precision transmission mechanism wears out, there will be backlash on the tooth side, and its transmission performance will inevitably decline. Only a momentary backlash-free meshing transmission can no longer meet the requirements of the precision transmission mechanism for transmission accuracy.

The cycloidal ball planetary reducer has a stage clearance elimination mechanism that cannot achieve continuous elimination of the tooth side clearance, and a stepless clearance elimination mechanism cannot achieve a constant axial force output, and the axial movement of the planetary disk is subject to greater frictional resistance
