Technical Field

[0002] The drum gear coupling polishing machine is a mechanical equipment specially used for surface polishing of drum gear couplings. Drum gear couplings are widely used in the field of engineering technology due to their compact structure, strong load-bearing capacity, high transmission efficiency, low noise and other advantages. Polishing treatment is of great significance in improving the surface finish of the coupling, reducing the friction coefficient and extending the service life.
