Name : Variable speed pulleys 11.101/104
Code : 070203
Simplabelt variable speed pulleys type 11.101/104
Spring-loaded variable speed pulleys types 11.101 and 11.104are usually mounted onto the input side of the motor shaft end; the driven pulley is mounted onto the driven shaft.
The output speed is determined by the diameter of the driven pulleys.
Simplabelt variable speed pulleys type 11.101
Thanks to their design ? cast iron disc pulleys on both ends and their high rotating mass, the variable speed pulleys type 11.101 provide good damping features which are advantageous for the use with changing loads, for instance for clock-pulse operating machines.
The pretension required for power transmission is generated by the disc springs which are located on both sides of the disc pulleys.
The forces resulting from the torque transmission are taken up by a well dimensioned serration. By this, the surface pressure is far below the permissible limit and thus the service life is very long.

Simplabelt variable speed pulleys type 11.104
With this type, the disc pulleys are made of a light-metal alloy especially developed for pulleys. Their main characteristic is a low moment of inertia.
We also offer the economical type 11.104 for operating conditions where a low moment of inertia is favorable because of high switching frequencies or reversing operation.
The pretension required for the power transmission is here generated by cylindrical pressure springs which are located rotation-symmetrically on both sides of the disc pulleys.
