Description
Larger size of monolithic gearboxes is made of machine cast iron. For smaller sizes gearboxes is used die-cast aluminum. Thanks to the precise machining of all surfaces, these gearboxes excel in high connection variability. The worm gear units of the CR, CB series are lightweight and require less installation space. The transmission ratio is formed using a conventional worm gear and a front gearbox at the transmission input, which allows higher gear ratios or better efficiency for the same gear ratios than gearboxes without a front gearbox. The gearboxes are of modern construction made of high-quality materials for maximum reliability and durability. The ground worm shaft is made of case-hardened and hardened steel. The worm wheel has a cast iron hub with a bronze ring. The friction in the gears is eliminated by the Z1 profile, which improves the contact between the tooth surface. Improves operating parameters and reduces operating noise. The standard design is a hollow output shaft, but the gearboxes allow the connection of modular accessories in the form of output shafts and flanges, a second input shaft, torque limiter or torque arm.
