Product catalog summary

Introduction
The RC3 series of SPN planetary gears is designed to meet the high demands of modern drive technology, especially when used with servo motors. These gears are suitable for high-dynamic processes in mechanical and special mechanical engineering, as well as for feeding and positioning units. They are used across various industries requiring drive technology.

SPN Planetary Gear Lines
The document outlines various types of SPN planetary gears, each designed for specific applications:

U3/UZ3-gears: Backlash-reduced planetary gear with aluminum-cast housing for good heat dissipation.
PK3/UK3-gears: Planetary bevel gear unit with a bevel gear, offering 72 ratios from i = 3 to 700.
U4/UZ4-gears: High-performance planetary gear for high radial loads with backlash < 5’.
RC3/RCZ3-gears: Compact, twisting-resistant planetary gear for robot applications with backlash < 3’.
E1/EZ1-gears: Robust planetary gear for standard servo drives.
P3/PZ3-gears: Backlash-free planetary gear for high positional accuracies.

Constructive Features
The RC3 series features easy motor installation, high efficiency (>96%), and high rigidity due to oversized shafts. It has a compact, twisting-resistant steel housing and is capable of handling high radial loads. The gears are lubricated with synthetic oil for high durability.

Technical Data
The RC3 series includes single-staged and two-staged gears with various motor shaft diameters and mass moments of inertia. The gears have a torsion rigidity of 50 to 150 Nm/rad and a maximum rotation speed of 6000 min-1. They operate within a temperature range of -25°C to +80°C and have a protection rating of IP64.

Dimension Sheet
Dimensions for the RC3 series are provided, with specifications for single-staged and two-staged configurations. The document includes detailed measurements for various gear types.

Evaluation
The optimal size of the SPN planetary gear is determined by output torque, ratio, output speed, and load phase duration. The document provides formulas for calculating equivalent output torque and conditions for selecting gear size.

Max. Radial and Axial Loads
The RC3 series gears are equipped with groove ball bearings on the output side. Diagrams are provided to determine the maximum allowable radial and axial forces on the output shaft.

Extensions
SPN gearboxes can be equipped with condition monitoring systems to measure torque, speed, axial and radial forces, acceleration, acoustic measurements, and oil condition. This allows for optimization of procedures and preventive maintenance.

Contact Information
SPN provides comprehensive services and products in drive technology, including worm gears, spur gears, and more. Their goal is to ensure customer success through quality and efficiency.
