The main advantages of drum gear coupling include: After carburizing and quenching, the tooth surface of drum teeth has high bearing capacity. The main failure mode of drum teeth is wear. After adopting forced thin oil lubrication, the wear of tooth surface decreases greatly, and the wear amount is about 10% of that of grease lubrication. The circulating thin oil can take away the rolling heat and the heat generated by the friction of the gear, and effectively prevent the allowable contact stress of the material surface of the gear; Under normal conditions, there will not be tooth breakage, to meet the requirements of the working characteristics of continuous rolling mill; The drum gear coupling can meet the requirements of the inter-roller rolling in the rolling mill; Safe, clean and efficient operation.
Contact conditions of teeth can be improved.
The external teeth of drum gear coupling are divided into straight teeth and drum teeth. The drum gear coupling allows greater angular displacement (relative to the straight teeth coupling), improves the contact conditions of the teeth, improves the ability to transfer torque, and extends the service life. The contact state along the tooth width with angular displacement.
The drum gear coupling has the ability to compensate radial, axial and angular axis deviations. It has the advantages of compact structure, small rotating radius, large bearing capacity, high transmission efficiency, low noise and long maintenance cycle. The toothed coupling shall work in a good and airtight condition.
