I. Product Overview

II. Core Technical Parameters

III. Structure and Core Features

1. Two-stage transmission structure

1. It employs a combination of “single-stage planetary reduction + two-stage harmonic gear reduction” to achieve a high reduction ratio, high rigidity, and low backlash, delivering excellent transmission accuracy and stability.
2. Integrated high-rigidity bearing design

1. Equipped with an integrated cross-roller bearing, it can withstand high radial and axial loads as well as overturning moments, eliminating the need for additional support structures, thereby significantly simplifying equipment design and reducing installation costs.
2. Strong load-bearing and shock-resistant capability

1. The cycloidal structure with multiple teeth engaging simultaneously offers strong resistance to impact and overload, making it well-suited for robotic joints that experience frequent start‑stop cycles.
2. Standardized Adaptation Design

1. The coaxial input structure can be directly matched with standard servo motors, offering convenient installation and representing a classic configuration for medium- to heavy-duty robot joints.

IV. Typical Application Scenarios

• Industrial Robot: 2–6-axis joint drive for medium-to-heavy-duty 6-axis robots (with a payload of approximately 50–100 kg)
• Welding/Cutting Positioner: Rotary Drive for 300–800 kg‑class Positioners
• Machine tool rotary tables, heavy-load indexing mechanisms for precision automated production lines, and heavy-duty packaging equipment

V. Model Naming Conventions

• RV-80E : Series model (80 is the specification code, corresponding to torque and size; E denotes the solid‑shaft series)
• 129 : Reduction ratio
• B : Output flange / shaft mounting type
• P : Accuracy class or additional specifications
