Transmission Error in Helical Synchronous Belt Drives. Effect of Belt Side Tracking.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1997 A new helical synchronous belt has been developed to reduce noise. However, in addition to the noise characteristics, the transmission characteristics must be considered. The present study examines experimentally the transmission error in a helical synchronous belt drive caused by side tracking of the belt due to the helix angle of the tooth trace ...

Noise of Helical Synchronous Belt Drives. Effect of Helix Angle.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1996 A new helical synchronous belt was developed for the purpose of noise reduction. Dimensions of the helical belts are based on the 8 mm pitch curvilinear synchronous belt, called YU, for automotive engines. The helix angles of the helical belts are 3°, 5°and 10°.
