FINE TREATMENT APPARATUS FOR INTERNAL GEAR SURFACE

WIPO Patent Application WO/2022/261891

A1

Disclosed is a fine treatment apparatus for an internal gear surface, comprising a base (1) fixedly connected to an abrasive flow device. The base (1) is provided with a port (10) connected to a discharge of the abrasive flow device. The base (1) is detachably connected to a sleeve (2) used for wrapping an internal gear. The sleeve (2) is detachably connected to a cover (3). The cover (3) is slidably and sealably connected to the abrasive flow device. The cover (3) is provided with a port (31) connected to a feed of the abrasive flow device. When the base, the sleeve, and the cover are connected and mounted to the abrasive flow device, the tooth surface burrs and the inner hole burrs of the internal gear can be removed. At the same time, scratches on the internal gear surface are repaired. The power of abrasive particles extruded by the abrasive flow device is used to drive the internal gear to rotate, the removal efficiency of the abrasive flow is improved, and upper and lower end surfaces and the outer side surface of the gear are repaired and deburred.
