Description

Technical Field

[0001] The utility model relates to the technical field of deburring devices, in particular to a roller type gear stable deburring device. Background Art

[0002] In a planetary finishing machine, an appropriate amount of abrasive (such as grinding stone, abrasive, etc.) is usually added. When the planetary gear drives the abrasive to contact the gear surface, the abrasive will rub and cut the gear surface, thereby removing the burrs on the surface.

[0003] However, when working, the main function of the sealing cover of the grinding drum is to prevent the material or processing medium from leaking out of the grinding drum. However, the sealing cover is usually fastened with bolts, which is easy to loosen after long-term use, resulting in poor stability and possible material leakage, which may affect the normal operation and processing quality of the equipment. For this reason, a drum-type gear stable deburring device is designed in this case. Utility Model Content
