1. Product Overview

The cycloidal pin-wheel reducer, also known as cycloidal gearbox or cyclo drive, is a high-precision, high-rigidity planetary speed reduction device with a unique cycloid-pin gear meshing structure. Different from traditional gear reducers, it adopts eccentric planetary transmission principle, featuring multi-tooth simultaneous meshing during operation. This structural design endows the product with outstanding shock resistance, ultra-low backlash, high transmission efficiency and compact overall size, making it a superior power transmission solution for heavy-duty, high-precision and continuous industrial operation scenarios.

Widely recognized for stable performance and long service life, our cycloidal pin-wheel reducers cover multiple series and complete specifications. They can perfectly replace traditional gear reduction equipment and are widely applied in mechanical speed regulation and torque amplification for various industrial automation and mechanical equipment.

2. Working Principle & Structural Features

The reducer mainly consists of three core components: eccentric input shaft, cycloidal gear disc and fixed pin-wheel housing. During operation, the eccentric shaft drives the cycloidal disc to perform planetary eccentric motion, and the cycloidal teeth mesh with the fixed pin teeth on the pin-wheel to realize speed reduction. Finally, the low-speed and high-torque power is output through the pin shaft output mechanism.

The core structural advantage lies in multi-tooth simultaneous meshing. More than 60% of the gear teeth participate in meshing transmission at the same time, which avoids the problem of single-tooth stress concentration of ordinary gear reducers. The integral high-strength housing and precision bearing matching further optimize the structural stability, effectively preventing tooth breakage, deformation and mechanical failure under heavy load and impact conditions.

3. Core Product Advantages

• High Load Capacity & Strong Shock Resistance: Multi-tooth meshing structure realizes uniform load distribution, with excellent impact resistance and overload resistance. It can stably cope with frequent start-stop, sudden load changes and heavy-duty impact working conditions, not easy to damage parts.

• Large Reduction Ratio & High Transmission Efficiency: The single-stage reduction ratio ranges from 9 to 87, and the two-stage reduction ratio can reach up to 7569. The transmission efficiency of single-stage reducer is up to 95%, with low power loss and energy-saving operation.

• Compact Size & Light Weight: The planetary transmission structure greatly reduces the overall volume and weight compared with helical gear reducers with the same torque. It saves installation space and is suitable for equipment with limited assembly space.

• Ultra-low Backlash & High Precision: Precision cycloidal disc and pin-wheel matching design realizes tiny backlash, with high positioning accuracy and repeatability. It meets the high-precision transmission requirements of automated equipment, robot joints and CNC equipment.

• Low Noise & Stable Operation: Smooth tooth profile meshing and balanced planetary motion effectively reduce operation vibration and friction noise. The whole machine runs smoothly without abnormal noise during long-term continuous operation.

• Long Service Life & Low Maintenance: Wear-resistant alloy materials and heat treatment process improve the wear resistance and fatigue resistance of key parts. Partial models adopt long-life grease lubrication, realizing maintenance-free operation for a long time and reducing later use cost.

• High Safety & Durability: Integrated thickened housing structure, strong rigidity, no tooth breakage failure, good seismic and compression resistance, adapting to harsh industrial environments such as dust, high temperature and humidity.
