RV Cycloidal Pinwheel Reducer

Product Overview

RV series cycloidal pinwheel reducer adopts cycloid-pin gear precision meshing technology to achieve a single-stage transmission ratio of 7-87 and an output torque range of 35N·m to 6,300N·m. With zero backlash and high rigidity as its core advantages, the Cycloidal Pinwheel Reducer is designed for high-precision scenarios such as industrial robot joints, CNC machine tool rotary tables, and automated production lines. It is compatible with servo/stepper motor interfaces, has a protection level of IP65, positioning accuracy ≤1 arc minute, and repeat positioning accuracy ±15 arc seconds.

Product Features

High-precision cycloid transmission

The cycloid wheel is carburized and quenched (HRC58-62), the tooth shape error is ≤5μm, and the transmission efficiency is ≥90%.

Compact modular design

The axial size is 40% shorter than that of the planetary reducer, and supports 8 installation configurations: flange/shaft-mounted/foot-mounted.

Zero clearance output

Patented cross slider compensation mechanism, radial runout <0.02mm (ISO 1328 standard).

Heavy-load impact resistance

3 times instantaneous overload capacity, passed 2 million start-stop durability test (ISO 6336 standard).

Wide temperature range adaptability

Uses low-temperature lithium-based grease (-30℃~120℃), applicable altitude ≤4000 meters.

Product advantages

Precision guarantee: standard anti-backlash mechanism, angular transmission error is 50% lower than that of harmonic reducer

Low maintenance cost: fully enclosed oil bath lubrication, oil change cycle up to 30,000 hours (IP protection maintenance-free design)

Global certification: CE, RoHS certified, compatible with EtherCAT/CANopen industrial bus protocol

Customized service: hollow shaft + locking disk, customized flange hole and anti-corrosion coating (PTFE/Ni-P) can be provided

Typical application scenarios

RV Cycloidal Pinwheel Reducer is widely used in:

FAQ Technical Answers

Q1: How to choose between cycloid reducer and harmonic reducer?

RV series is more suitable for high torque scenarios (＞200Nm), with a lifespan three times longer than that of harmonic reducers, and suitable for 24/7 continuous operation

Q2: How to achieve precise return clearance adjustment?

By adjusting the end cover pre-tightening bolts (torque value 28N·m±10%), the clearance can be controlled in the range of 0~5 arc minutes

Q3: Does it support multi-stage series use?

Supports two-stage series connection (speed ratio extended to 1:7500), and requires customized intermediate connection flanges and lubrication systems

Q4: How to choose and replenish grease?

Recommend KLUBER ISOFLEX TOPAS L32 grease, replenish 50ml through the grease nozzle every 10,000 hours
