Burr polisher for gear machining

Abstract

The invention relates to a burr polisher for gear machining. The burr polisher comprises a base, the base is internally provided with a driving chamber, the driving chamber is internally provided witha driving motor, the base is rotatably provided with a brush shaft, and the driving motor drives the brush shaft to rotate; the brush shaft is fixedly provided with a wheel brush, the wheel brush comprises a brush wheel hub, the outer side wall of the brush wheel hub is evenly provided with a plurality of clamping grooves extending in the axial direction of the brush wheel hub, the clamping grooves are internally provided with brush strips, and the brush strips are in tooth shapes; and the burr polisher further comprises a gear supporting shaft fixed on the base, the gear supporting shaft isfurther slidably provided with a lower friction disc and an upper friction disc, the lower side of the lower friction disc is provided with a bearing supporting part, the upper side of the upper friction disc is provided with a compressing part, and the bearing supporting part and the compressing part are both fixed on the gear supporting shaft. By means of the burr polisher for the gear machining, comprehensive polishing on gear end surfaces and gear teeth can be realized, meanwhile, because the gear supporting shaft is vertically arranged, installation of gears to be performed burring is facilitated, the gears and a brush wheel contact highly consistent, and the polishing uniformity of each gear tooth is good.

Description

technical field [0001] The invention relates to gear processing equipment, in particular to a burr grinding machine for gear processing. Background technique [0002] Gear is a mechanical element with teeth on the wheel rim, which can continuously mesh and transmit motion and power. It appeared very early in the application of transmission. Because of the stability and continuity of transmission, it is widely used in various fields of machinery; It is one of the essential components in the gearbox. The quality of the gear determines the stability of the transmission, the accuracy of the reduction ratio, and the vibration and noise transmitted. In the cycloid reducer, the tooth profile accuracy of the gear And flatness requirements are higher. After the gear is processed by the gear processing machine tool, some burrs will inevitably remain on the surface, making the surface not smooth. This kind of gear that has just been processed is generally not sold directly, and the b...

Problems solved by technology

Since the gear is placed between the two friction discs and the end of the crank rod is inserted into the shaft hole of the gear, the end of the crank rod inserted into the shaft hole is arc-shaped when the crank rod rotates, so in order to make the crank rod can be inserted into the shaft normally In the hole, the outer diameter of the crank rod needs to be set smaller than the shaft hole, so that when the gear is in contact with the friction barrel, there is shaking up and down, and the uniform grinding of each gear tooth cannot be well achieved.
