Hebei WG drum gear coupling
The WG drum gear coupling is to make the external teeth into a spherical surface. The center of the spherical surface is on the gear axis. The tooth side clearance is larger than that of ordinary gears. The drum gear coupling can allow larger angular displacement (relative to straight Gear coupling), which can improve the contact conditions of the gears, improve the torque transmission capacity and prolong the service life.
The WG drum gear coupling has a contact state along the tooth width when angular displacement. The gear coupling is composed of an inner gear ring with the same number of teeth and a flange half coupling with external teeth.The external teeth are divided into two types of teeth, straight teeth and drum teeth. When the gear coupling is working, the two shafts produce relative angular displacement. The tooth surfaces of the internal and external teeth periodically slide relative to each other in the axial direction, which will inevitably cause tooth surface wear and tear. Power consumption, therefore, gear couplings need to work in a good and sealed state.Gear couplings have small radial dimensions and large load-bearing capacity. They are often used in shaft transmissions under low-speed and heavy-duty conditions. The dynamically balanced gear couplings can be used for high-speed transmissions, such as gas turbine shaft transmissions.
Since the angular compensation of WG sleeve drum gear couplings is greater than that of straight gear couplings, drum gear couplings are widely used. Straight gear couplings are obsolete products, and those who choose to choose should try not to use them. .
The classification of WG sets of drum gear couplings is introduced:
WGP type-drum gear coupling with brake disc (JB/T7001—93)
WGC type—vertical installation drum gear coupling (JB/T7002-93)
WGZ type-drum gear coupling with brake wheel (JB/T7003-93)
WGT type—connecting to the middle sleeve drum-shaped gear coupling (JB/T7004-93)
TGL type—nylon inner gear ring drum gear coupling (JB/T5514—91)
WGJ type-drum gear coupling with intermediate shaft (JB/T8821-1998)
NGCL type—with brake wheel type (JB/ZQ4644-97)
NGCLZ type—with brake wheel type (JB/ZQ4645—97)
WG type—with brake wheel type (JB/ZQ4186—97)
