The coupling K 72122 is a precision-engineered mechanical interface used to connect the orbit motor K 72104 with the associated drive components in the Sulzer ZV40/48 engine. Designed to transmit torque efficiently while compensating for minor misalignments, this coupling ensures smooth power transfer and reduces the impact of vibration and shock loads on the system. Constructed from durable, high-strength materials, it provides reliable performance under continuous operation and demanding mechanical conditions. By maintaining stable torque transmission and protecting connected components from excessive stress, the K 72122 coupling plays a vital role in ensuring the efficiency, reliability, and longevity of the orbit motor drive system.
