Product Overview
This inline planetary gearbox, also used as an inline planetary gear reducer, provides a compact coaxial transmission for AGV, AMR, mobile robot and servo-driven automation systems. The input and output are arranged on the same axis, combining 42 N·m rated output torque, 10:1 reduction ratio, ≤3 arcmin backlash and IP65 protection in a compact transmission package. For broader project matching, see our AGV/AMR gearbox and servo gear reducer solutions.
The gearbox delivers a rated output torque of 42 N·m and an emergency braking torque of up to 126 N·m, with a maximum input speed of 3000 r/min and a reduction ratio of 10. Backlash is controlled to ≤3 arcmin, operating noise is ≤58 dB, and the unit provides IP65 protection with an operating temperature range of −10°C to +90°C.
Key Features
Compact Coaxial Transmission Design
The inline coaxial layout keeps the input and output along the same axis, providing a compact structure for easy integration with servo motors and mobile-robot drive systems.
42 N·m Rated Torque Output
Rated output torque reaches 42 N·m, with emergency braking torque of up to 126 N·m, supporting frequent starts, stops and short-term high-load operating conditions.
≤3 arcmin Low-Backlash Precision Transmission
Backlash is controlled to ≤3 arcmin, with a torsional stiffness of 3.5 N·m/arcmin, helping improve transmission response and positioning accuracy for servo-driven and precision automation applications.
Low-Noise, High-Speed Stable Operation
Maximum input speed reaches 3000 r/min with operating noise of ≤58 dB. IP65 protection and an operating temperature range of −10°C to +90°C support stable operation across a wide range of industrial environments.
