Description

Technical Field

[0001] The utility model relates to the field of deburring, in particular to a gear tooth profile deburring device. Background Art

[0002] Gears refer to mechanical components with teeth on the rim that can continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. At the end of the 19th century, the principle of the gear cutting method and the special machine tools and tools that use this principle to cut gears appeared one after another. With the development of production, the smoothness of gear operation has been paid attention to. Generally, there are gear teeth, tooth grooves, end faces, normal faces, tooth top circles, tooth root circles, base circles, and pitch circles. Gears are a common part often used in mechanical transmission. Gears are made of high-quality high-strength alloy steel, with surface carburizing and hardening treatment, strong load-bearing capacity, and durability. In practical applications, helical gears, as a type of gear, are widely used because of their stable transmission, low impact, vibration and noise.

[0003] For example, in the gear tooth profile deburring device disclosed in the utility model with authorization announcement number CN219562470U, the gear rotates together with the sleeve under the drive of the rotating grinding part, and the tooth profile of the bevel gear rolls on the surface of the rotating grinding part. The burrs of the gear tooth profile are polished away during the rolling of the gear tooth profile on the surface of the rotating grinding part. When deburring the gear tooth profile, when adjusting the position of the copper wire wheel, the copper wire wheel and the gear are far apart, and the copper wire wheel cannot have good contact with the gear tooth profile, so that the copper wire wheel has a poor deburring effect on the gear tooth profile. When the copper wire wheel and the gear are close, the wear of the copper wire wheel on the gear tooth profile is increased. Utility Model Content
