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 Design: Achieves high reduction ratios (9:1 to 87:1 for single-stage, up to 5000:1 for multi-stage) in a small footprint, with nearly 50% tooth contact for low vibration and noise.
High Torque Output: Capable of handling large radial loads and momentary overloads up to 200% of rated capacity.
Smooth Operation: Low backlash, minimal noise, and stable performance due to multiple meshed teeth and high overlapping coefficients.
Durability: Hardened tooth surfaces and robust construction ensure a long service life (over 10,000 hours) with minimal maintenance.
Versatility: Available in various configurations, including flange-mounted options, and compatible with standard motors.
What is the XLD Series Cycloidal Pinwheel Speed Reducer?
The XLD Series is a vertical flange-mounted cycloidal reducer that directly couples to a motor. It operates on the principle of planetary transmission with cycloidal pinwheel meshing, where an eccentric input drives a cycloidal disc that engages with stationary pins to produce reduced output rotation. This design replaces traditional multi-stage cylindrical or worm gear reducers, offering a compact, high-torque solution.
What are the key features and advantages?
High Reduction Ratios: Single-stage: 9:1 to 87:1; double-stage: up to 7,569:1; multi-stage options available for even higher ratios (e.g., 1/2057 to 1/537,399). Low Backlash and Smooth Operation: Zero-backlash design with rolling contact (no shear forces), resulting in low noise, vibration, and stable running. Compact and Lightweight: Smaller volume and lighter weight than equivalent power-rated gear reducers due to coaxial input/output shafts. Durability: Robust construction using high-quality materials like chrome-molybdenum steel; handles heavy loads with reduced friction via rollers on pins. Versatility: Available in models like XLD1 to XLD12, suitable for various mounting (vertical flange) and motor integrations.
What are XLD Series Cycloidal Pinwheel Speed Reducer main applications?
Textile printing and dyeing machinery. Light industry (food processing). Metallurgy, mining, and petrochemical equipment. Lifting, transportation, and construction machinery. Conveyor systems, agitators, and pumps requiring high torque at low speeds.
How does it work?
The input shaft drives an eccentric bearing, causing the cycloidal disc to wobble in an eccentric path. The disc's perimeter engages with fixed ring gear pins, while output shaft pins or rollers pass through the disc's face. This converts the wobbling motion into steady rotation without transmitting radial forces to the output. The reduction ratio is calculated as (number of ring gear pins - number of cycloidal lobes).
What models are available in the XLD Series?
XLD1 to XLD12 (based on size/power rating, e.g., XLD1 for smaller applications, XLD12 for larger). Configurations: Single-stage vertical direct-coupled; can be combined for multi-stage. Related variants: XWD (standard horizontal), XL (vertical non-coupled), XW (horizontal non-coupled).
What motors are compatible?
Standard AC motors, brake motors, explosion-proof motors, or variable-speed motors. Direct-coupled design (e.g., with IEC-normalized flanges) for seamless integration. Hydraulic motors also supported in some configurations.
