Germany STOEFFL RUDOLF coupling STOEFFL RUDOLF model STOEFFL RUDOLF price
STOEFFL RUDOLF couplings consist of components such as an internal gear ring with the same number of teeth and flanged half-couplings with external teeth. External teeth are divided into 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 general 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. When gear couplings are in operation, relative displacement occurs between the two shafts, and the tooth surfaces of the internal and external gears periodically slide axially relative to each other.
German STOEFFL RUDOLF bearings, STOEFFL RUDOLF models, STOEFFL RUDOLF prices
STOEFFL RUDOLF bearings are bearings that operate under sliding friction. Plain bearings operate smoothly, reliably, and without noise. Under liquid lubrication conditions, the sliding surfaces are separated by lubricating oil without direct contact, which can greatly reduce friction loss and surface wear; the oil film also has a certain vibration-absorbing capacity. However, the starting friction resistance is relatively high. The part of the shaft supported by the bearing is called the journal, and the part mating with the journal is called the bearing bush. The anti-friction material layer cast on the inner surface to improve the friction properties of the bearing bush surface is called the bearing lining. The materials of the bearing bush and bearing lining
