Technical Field

[0002] Planetary gears refer to a gear system that, in addition to being able to rotate around its own axis like fixed-axis gears, also has its axis rotate around the axis of other gears along with the planetary carrier. During processing and assembly, the gears must be smooth, free of cracks and damage, and their working surfaces must be free of burrs and bite marks. The gears must also be wear-resistant and have high precision. Therefore, the gear edges of the planetary gear reducer require surface grinding treatment.

[0004] However, in actual use, the above-mentioned surface treatment equipment uses two inner support blocks to clamp the gear internally, and the contact surface is too small. When the friction between the grinding device and the inner support blocks is large, the gear will rotate with the rotation of the grinding device, resulting in uneven surface treatment of the gear and a decrease in accuracy. In view of this, we propose a gear surface treatment equipment for planetary gear production. Summary of the Invention
