The XWD series is a popular line of cycloidal pinwheel speed reducers (also known as cycloid drives or cycloidal gearboxes) .These reducers are designed for industrial applications requiring high torque, compact size, and reliable speed reduction. They operate on the principle of planetary transmission with cycloidal pinwheel meshing, where an input shaft drives eccentric cams or pins that engage with rolling pins inside a cycloid disc, creating overlapping orbits for smooth output rotation.
| Item | Parameters |
| Power | 0.12-90kW |
| Speed Ratio | 7-650000 |
| Maximum Output Torque(kN.m) | 30kN.m |
Compact and Efficient Design: Achieves high reduction ratios (typically 9:1 to 87:1 in single stage) in a small footprint, with nearly 50% tooth contact for minimal vibration and noise.
High Torque Capacity: Supports large radial loads and overloads up to 200% momentarily.
Smooth Operation: Low backlash, stable running, and reduced noise due to multiple meshed teeth and high overlapping coefficients.
Durability: Hardened tooth surfaces, long service life (over 10,000 hours), and modular construction for easy maintenance.
Versatility: Available in horizontal (XWD), vertical (XLD), double-shaft (XW), and flange-mounted variants.
What is the XWD Series Cycloidal Pinwheel Speed Reducer?
It’s a type of cycloidal gearbox that uses a pinwheel mechanism to achieve high torque and speed reduction in a compact design. The "XWD" designation indicates a horizontal-mounted reducer directly coupled to a standard electric motor.
What are the main advantages of the XWD Series?
High torque output with compact size. Smooth, low-noise operation due to multiple tooth engagement. High reduction ratios (9:1 to 87:1 for single-stage, up to 5000:1 for multi-stage). Durable with long service life (over 10,000 hours). Shock-resistant, suitable for frequent start-stop applications.
What are typical applications for the XWD Series?
Material handling (conveyors, lifts). Manufacturing (textile, printing, packaging). Chemical/food processing (mixers, agitators). Heavy industry (mining, metallurgy, construction). Marine, agriculture, and robotics.
What reduction ratios are available?
Single-stage ratios range from 9:1 to 87:1. Multi-stage configurations can achieve ratios up to 5000:1, depending on the model and manufacturer.
What is the power range for XWD Series reducers?
Input power typically ranges from 0.12 kW (XWD1) to 7.5 kW (XWD12), with output torque from 10 Nm to 25,000 Nm, depending on the model.
How does the cycloidal mechanism work?
An eccentric shaft (driven by a motor) rotates a cycloid disc, which meshes with pins in a fixed ring gear. The disc’s motion reduces speed and transfers torque to the output shaft, achieving high reduction ratios with minimal backlash.
