Applications  Cam Clutch - 2. Detachable ski lift

Application

Overrunning

An application to alternately repeat the conditions where the inner and outer races of the cam clutch engage to transmit the torque and where they continue spinning around depending on the difference in the rotation speed or rotation direction. The operation is the same as the free wheeling of a car.

Purpose of Use and Operation Overview

This is an example where a cam clutch is used to adjust the speed between fast and slow at the location where people get on/off multiple-person ski lifts.

  1. The ski lift is operated at slow speed at the location where people get on/off and at faster speed while people are riding.
  2. The lift is detached from the main cable before it arrives at the riding position and transferred from the high speed side to the low speed side by a wheel containing a cam clutch via a plate-shaped part at the top of the lift.
  3. This wheel usually rotates at low speed because the cam clutch engages. When a lift arrives at high speed, the outer race of the cam clutch overruns to allow smooth entry to the low speed side.
  4. When the lift decelerates to a speed below the wheel rotation, the cam clutch engages automatically to move the lift at low speed.

Advantage of using the cam clutch

  • ・The cam clutch switches between overrunning and engagement automatically simply based on the difference in the rotation speed.
  • ・Smooth speed change is ensured without the need for a device controlling speed differences.
