Variable Speed Drives
from Lovejoy, Inc.

Very economical and reliable method of speed change. Allows the user to find the ideal speed without changing sheaves and belts; especially important on applications where final driven speed is critical and difficult to attain with two fixed-diameter sheave. Speed range within the ratio is infinite,... [See More]

Geared Variable-Speed Coupling -- R..A
from Voith Turbo Inc.

Step-down gear for low-speed driven machines. The coupling is fitted with a helical reduction gear on the output side. By adding a hydrodynamic brake (optional) with a appropriate braking torque characteristic, the heavy masses of the driven machine can be rapidly decelerated. Benefits: Robust... [See More]
