Excellent starting efficiency RV Gearbox for Robots Arms High-Performance Cycloidal Pinwheel Reducer RV Reducer

Product Overview

RV series high-performance cycloidal gear reducers for robotic arms adopt double cycloid wheel-pin gear housing precision meshing technology to achieve a single-stage transmission ratio of 11-289 and a rated output torque of 50N·m~4200N·m. The cycloidal gear reducer is certified by ISO 1328-1:2018, and its axial rigidity is 3 times higher than that of planetary reducers. It is designed for high-precision scenarios such as six-axis collaborative robots and medical surgical robotic arms. It is compatible with 100W-7.5kW servo motor interfaces, has a repeatability accuracy of ±10 arc seconds, and a protection level of IP67 (NEMA 6).

FAQ key technology answers

Q1: What is the difference in life between cycloidal reducer and harmonic reducer?

Under the same working conditions, the life of this product can reach 50,000 hours (average 20,000 hours for harmonic reducers)

Q2: How to ensure transmission accuracy in a humid environment?

Optional silicon nitride ceramic coating version (friction coefficient reduced by 37%), suitable for 95%RH humidity environment

Q3: How to diagnose abnormal vibration of the reducer?

Use a vibration analyzer to detect the 3kHz~5kHz frequency band. If the spectrum abnormality value exceeds 4mm/s², it needs to be returned to the factory for inspection

Q4: Does it support modular quick replacement?

Provide Plug-and-Play quick-change module (including positioning pin + hydraulic locking mechanism), on-site replacement time ≤15 minutes
