German TSUBAKI coupling TSUBAKI model TSUBAKI price

TSUBAKI couplings consist of components such as an internal gear ring with the same number of teeth and a flanged half-coupling with external teeth. External teeth are available in two tooth profiles: straight teeth and crowned teeth. Crowned teeth refer to external teeth machined into a spherical surface, with the center of the sphere on the gear axis. The backlash is larger than that of standard gears. Crowned tooth couplings allow greater angular misalignment (compared to straight-tooth couplings), improve tooth contact conditions, increase torque transmission capacity, and extend service life. During operation of gear couplings, relative displacement occurs between the two shafts, and the tooth surfaces of the internal and external gears periodically slide axially relative to each other, inevitably forming
