Product catalog summary

Introduction
The SPN planetary gears are 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 across various industries.

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

U3/UZ3-gears: Backlash-reduced planetary gear with aluminum-cast housing for efficient heat dissipation.
PK3/UK3-gears: Planetary bevel gear unit with a wide range of ratios.
U4/UZ4-gears: High-performance planetary gear for high radial loads.
RC3/RCZ3-gears: Compact, twisting-resistant planetary gear for robot applications.
E1/EZ1-gears: Robust planetary gear for standard servo drives.
P3/PZ3-gears: Backlash-free planetary gear for high positional accuracy.

Constructive Features
The SPN planetary gears boast high transmittable power, efficiency greater than 96%, high rigidity, easy motor installation, and a long lifespan due to synthetic lubrication. They are designed for any mounting position and have a backlash of less than 10 arc minutes.

Technical Data
The document provides detailed technical specifications, including:

Mass moment of inertia at the input side.
Various gear ratios and their corresponding parameters.
Blocking torque, torsion rigidity, and efficiency.
Acceptable temperature range and protection system (IP64).

Dimension Sheet
Dimensions for different gear sizes are provided, with options for custom motor shaft dimensions and flange sizes upon request.

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

Max. Radial and Axial Loads
The document explains how to determine the maximum allowable radial and axial forces on the output shaft, with diagrams provided for quick reference.

Extensions
SPN gearboxes can be equipped with extensive measuring equipment for condition monitoring, including 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 support and additional products such as worm gears, spur gears, special gears, and more.
