WGP Type—Drum Gear Coupling with Brake Disc (JB/T7001-93)
A drum-shaped gear coupling with a brake disc. The coupling includes a left shaft sleeve and a right shaft sleeve for connecting the power input shaft and the power output shaft respectively. A drum-shaped shaft is provided at the end of the left shaft sleeve. Tooth, the coupling sleeve sleeved on the periphery of the left sleeve is engaged with the drum-shaped teeth on the left sleeve through its internal teeth, the end of the right sleeve is provided with a connecting flange, and the connecting flange and the coupling sleeve are connected by a through bolt Fixed, a brake disc is clamped and fixed between the connecting flange and the connecting sleeve.The drum gear coupling with brake disc has simple structure and easy installation. The brake disc is rigidly connected to the right bushing. The braking load and vibration during braking are borne by the right bushing, so the drum gear will not be affected. The meshing performance of the brake is damaged, and the stability of the brake disc itself is also improved, which improves the performance of the operation.The external teeth are divided into two types: straight teeth and drum teeth. The so-called drum teeth means that the external teeth are made into a spherical surface. The spherical surface is on the gear axis. The tooth side clearance is larger than that of ordinary gears. Drum-shaped gear couplings are allowed. Larger angular displacement (compared to spur coupling) improves the torque transmission capacity and prolongs the service life.The contact state along the tooth width when there is angular displacement.
