A surface refinement treatment device for internal gears

Abstract

The invention discloses a device for refining the surface of internal gears, which includes a base; the base is fixedly connected with abrasive flow equipment, and the base is provided with an interface with the outlet of the abrasive flow equipment, and the base can be The detachable connection is provided with a sleeve for wrapping the internal tooth gear, the detachable connection of the sleeve is provided with a cover, the cover is in sliding and sealing connection with the abrasive particle flow equipment, and the cover is provided with a When the base, sleeve and cover are connected and installed to the abrasive flow equipment, the tooth surface burrs and inner hole burrs of the internal gear can be removed, and the scratches on the surface of the internal gear can be removed at the same time. Repair, and use the power of the abrasive equipment to squeeze out the abrasive to drive the internal gear to rotate, to enhance the efficiency of abrasive flow removal, and at the same time repair and deburr the upper and lower end surfaces and outer surfaces of the gear.

Description

technical field [0001] The invention belongs to the field of precision gears, and in particular relates to a device for refining the surface of internal gears. Background technique [0002] Internal gears are a common component for power transmission. Internal gears that transmit power through hydraulic pressure need to drill a hole on each tooth surface to communicate with the outside world. However, when processing the tooth profile and drilling of internal gears At the same time, a large number of burrs are often left on the tooth end surface and the connection between the drill hole and the tooth surface, which affects the power transmission of the gear. And the opening on the other side flows out to remove the burr, and the abrasive particles flow out directly to the external space. However, this method has low work efficiency and requires manual assistance to collect the abrasive particles into the equipment, and this method cannot be used without the end face of the i...
