Overview: Nabtesco Precision, part of the Nabtesco Group, is the leading global manufacturer of cycloidal precision gears, primarily used in industrial robotics. Their products are known for quality, efficiency, and compactness, supported by a global workforce and facilities.

Specifications and Features: Nabtesco's product range includes High Precision Reduction Gears, Hollow Shaft Gearheads, and Single Axis Servo-Actuators. Key features include high torque density, shock load capability, rigidity, and precision with minimal backlash. The gears utilize a unique pin gear design and a two-stage reduction system to minimize vibration and inertia.

Product Series: The document describes several gear series:

• RV-E Series: Offers high torsional and bending stiffness, compact design, and high precision with integrated angular-ball-bearings.
• RV-C Series: Similar to RV-E but includes a hollow shaft for cable or media routing.
• RV Series: The foundational design for precision gears, known for high precision and low backlash.

Technical Operation: RV gears operate by transmitting servo motor rotation through input and spur gears, reducing speed via gear ratios. The eccentric rotation of crankshafts and RV gears, with pins arranged in constant pitch, ensures precise motion control.

Applications: Nabtesco gears are ideal for demanding motion control tasks, such as tool magazines and NC rotary tables, providing solutions for high output speeds and specific industrial applications.

Introduction: This document outlines technical specifications and applications for Nabtesco gear units, designed for machine tools and NC rotary tables, highlighting features, benefits, and applications of series like RA-EA/EC, NT, RV-C, and RD-C.

Specifications: Derived from the RV-E/RV-C series, these gear units are sealed with lubricant for rotating tables. Key specifications include high torque density, shock load capability, high rigidity, precision, and a hollow shaft design.

Features and Benefits: The gear units offer high precision with low axial and radial runout, indexing accuracy, and repeatability. Various models are available to suit specific applications.

Applications: Designed for tool magazines and changers, NC rotary tables, and multi-axle tilting heads in machining centers for various industries.
