ANS ModelANS model is a belt-type stepless speed change drive. When turning the handle of the motor-side speed changer, the width of the speed change pulley will change. By varying the pitch diameter of the speed change belt, the pitch diameter of the machine-side speed change pulley will follow to change the rotation speed. Instead of the original coil spring, a disc spring with constant-pressure load is used for the machine-side pulley that follows the pitch diameter of the motor-side pulley. Due to the disc spring, the transmission efficiency is increased, and a stable variable-speed operation becomes possible. This model is incorporated directly into machines to save space.

CENTA FLEX A Model Motive power is transmitted though a high elastic rubber. It is excellent in absorbing vibrations and shocks. Noise of machinery is also reduced. The rubber part is composed of a polygon rubber and aluminum insert inserted at the top, and each part is tightly attached by vulcanizing. Power transmission is accomplished by fixing the rubber body in the hub and flange hub in a radial direction and axial direction respectively by bolts. Especially for a radial directional coupling, a precompressed construction of deformed rubber body enables a power transmission excellent in flexibility and absorbing vibrations and shocks. Rubber parts are available in two types, bolt mounted type (O0) and bayonet mounted type (S0).

By using a unique claming mechanism (CENTA-LOCK), mounting in a spline shaft is possible. Hub and spline shafts are completely fixed by using a clamping hub of the CENTA-LOCK mechanism. No fretting wear is caused. (Clamping hub of the CENTA-LOC mechanism is available by special order.)
