Description
The BELTWORTH Molded cogged Raw Edge Variable speed belts have been developed specifically for stepless variator drives. Increasing demands on variable speed belts due to the continuous increase of power transmission levels initiated
the development of the raw edge, cogged variable speed belts. The base compound consists of a polychloroprene rubberCR RUBBER） compound with traverse fibers. The high quality and extremely low-stretch polyester or aramid tension cord is embedded in a rubber compound. It is effectively supported by an upper and substructure.
Further increases in demand on the performance of drive elements and the trend towards designing ever smaller, space saving drive units, led to the development of the Double-sided, BELTWORTH Molded cogged Raw Edge Variable speed belts. Double-sided BELTWORTH variable speed belts allow for the smallest pulley diameters, even below standard recommendations. The Double-sided design improves heat emission, thereby significantly reducing the belt running temperature. The production methods and the structure of the belt have been derived from the BELTWORTH Molded cogged Raw Edge Variable speed. Depending upon the application and application range, this belt can also be equipped with layers of special cross-cord material in the base compound. The belt is Double-sided, with the depth and spacing of the cogs matching with the specific belt profile. The polyester or aramid tension cord ensures ideal power transmission, increased service life, and extremely low-stretch characteristics.
Detailed Description:
