Sumitomo Cyclo Reducer 5.5 kW with 1:17 Ratio Gearbox

Description

This is a heavy-duty Sumitomo Cyclo Reducer, model CHHM8-6165-17/T, paired with a powerful 5.5 kW (7.5 HP) induction motor. Designed for high-speed output and extreme durability, this unit delivers a consistent 85 RPM. The unique cycloïd design ensures that the internal components share the load across multiple rolling elements, providing unmatched shock resistance and a significantly longer service life than traditional helical gearboxes. This unit is in excellent condition and ready for immediate industrial application.

FAQ

A 1:17 ratio provides a balance between high output speed (85 RPM) and substantial torque. It is more efficient than high-ratio units for applications where throughput speed is a priority without sacrificing the shock-absorbing benefits of the Cyclo mechanism.

The CHHM designation indicates a horizontal foot mount configuration. For vertical mounting, the lubrication system and internal seals must be specifically designed for that orientation (usually designated as CVVM). Mounting this horizontal unit vertically could lead to lubrication failure.

While Sumitomo Cyclo drives are ready for use, it is recommended to check the oil level after the first 50 hours of operation. Since the internal parts move through rolling contact, they are very efficient from day one, but initial monitoring ensures long-term reliability.
