Universal Coupling
|
A universal joint, (universal coupling, U-joint, Cardan joint, Hardy-Spicer joint, or Hooke's joint) is a joint or coupling in a rigid rod that allows the rod to 'bend' in any direction, and is commonly used in shafts that transmit rotary motion. It consists of a pair of hinges located close together, oriented at 90° to each other, connected by a cross shaft. The universal joint is not a constant velocity joint. WS universal coupling is suitable for retating system which the two axis angle <45,nominal torque 11.2~1120N*m. Features of WS universal coupling: 1.Available in your choice of round, hex, splined, or keyway bore
2.Lubrication is required for optimal wear – boots and lubricant extend universal joint life
3.Max angular mislegnment:45o
