Cycloidal Speed Reducer

Standard cycloidal drives for industrial and automation systems

  • High Efficiency
    Cycloidal reducers for industrial y automation systems use a rolling contact design that greatly reduces sliding friction and vibration during operation. Since multiple teeth share the load at the same time, torque transmission is smoother and energy loss is minimized. Efficiency can reach over 96% for single-stage setups and around 92% for two-stage configurations.
  • High Overload Resistance
    Thanks to the engagement between the cycloidal disc and the needle pins, many teeth work together simultaneously, up to 67%, which improves load distribution and prevents tooth damage. This structure gives the reducer an overload capacity of up to five times its rated torque, offering reliable protection under demanding conditions.
  • Reliable Quality and Warranty
    Each unit is built under strict quality control, from material processing to precision assembly. The use of rolling contact transmission further enhances durability and service life, ensuring consistent performance and dependable operation over time.

Cycloidal gearboxes, also known as cycloidal drives, are precision transmission systems designed to deliver high torque and accurate motion with minimal backlash. They operate through an eccentric mechanism that drives cycloidal discs to engage with needle pins inside the housing. This motion converts the motor’s input rotation into a stable, reduced-speed output, allowing smooth power transmission and consistent performance.

Cycloidal gearboxes offer a compact structure, high reduction ratios, and strong load capacity. They also feature low backlash and excellent impact resistance, which is ideal for equipment that requires precise positioning, smooth motion, and reliable performance under heavy or changing loads.

Selecting the right gearbox involves considering the required torque, reduction ratio, available installation space, and working environment. It’s also important to evaluate the type of load, duty cycle, and operational conditions to ensure efficient performance and long-term reliability.

The input shaft transfers rotational energy from the motor into the gearbox and initiates the eccentric movement inside. Its precision, balance, and alignment have a direct impact on the gearbox’s efficiency, stability, and overall lifespan.
