Product Information

Belt-type Stepless Speed Changer Units

Stepless speed changer units use variable-speed pulleys

These units change speeds without changing the distance between shafts by making the belt pitch diameter of one variable-speed pulley track the belt pitch diameter of another variable-speed pulley when its belt pitch diameter is changed. Since speed can be changed without changing the distance between shafts, more compact designs are possible, mounting is simple, and ease of use is exceptional. They can be combined with motor/speed reducer and electromagnetic clutches and brakes can also be built in. These units are easy to maintain and belt-type power transmission is efficient, helping to save energy.

ANS Models

Rotate the handle of the speed changer on the motor side to change the width of the speed-change pulley.When you change the pitch of the speed-change belt hanging from it, the pitch diameter of the speed-change pulley on the machinery side tracks it, for a belt-type stepless speed changer that can freely change the rotation speed. Instead of the coil spring that traditionally tracks the machinery-side pulley, the ANS models use a constant-pressure load disc spring to track the pitch diameter changes of the motor-side pulley. Use of a disc spring increases transmission efficiency and enables stable speed-change operation.
