DQ/WZL Drum Coupling

Ball Dumpling

WZL Drum Coupling is a spherical hinged coupling. It has a connecting flange with an inner spherical surface, a spherical semi-coupling sleeve with an outer spherical surface, a special transmission key, an inner and outer limit cover, etc. The internal control generally adopts the splined sleeve design, which transmits torque through a specially designed key bar and can withstand large torque and radial load. The maximum angular displacement compensation can reach 3°, with a life indicator and safe and reliable structure.
