Product catalog summary

Introduction
The SPN planetary gears are engineered to meet the rigorous demands of modern drive technology, particularly when paired with servo motors. They are ideal 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 describes several types of SPN planetary gears:

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

Constructive Features
The U4-series gears are optimized for transmitting large forces and torques with minimal mechanical play. Notable features include:

Simple motor installation with tangential clamping and patented sun wheel fixing.
Efficiency exceeding 96%.
High rigidity due to oversized shafts.
Compact, rigid steel housing with B5 flanging.
High radial load capacity thanks to optimized taper roller bearings.
Backlash less than 5 arc minutes.
High durability with synthetic oil lubrication.

Technical Data
Detailed technical data for the U4-series includes:

Motor shaft diameters and mass moments of inertia.
Output torque and torsion rigidity values.
Efficiency, lubrication, and temperature range specifications.
Protection system (IP64).

Dimension Sheets
Dimension sheets for various gear types (U43 to UZ48) provide detailed measurements in millimeters for gear and motor components.

Evaluation
The optimal size of the SPN planetary gear is determined by output torques, ratios, output speed, and load phase duration. Formulas for calculating equivalent output torque and conditions for selecting gear size are provided.

Max. Radial and Axial Loads
The U4-series gears feature taper roller bearings on the output side. Diagrams are included 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, accelerations, acoustic measurements, and oil condition. These measurements can be transmitted wired or wirelessly, aiding in preventive maintenance and process optimization.

Overview
The document highlights the capabilities and benefits of equipment designed to record various mechanical parameters without altering external dimensions. It details the types of measurements possible, data transfer methods, and support offered by the engineering department.

Specifications
The equipment can record torque, speed, axial forces, radial forces, acceleration, acoustic measurements, and oil condition. Additional measurements can be arranged by agreement.

Data Transfer
Measurements can be transferred via cable or wireless means, with sensors tailored to specific tasks.

Support
The engineering department offers assistance in signal evaluation and hardware/software selection.

Benefits
The equipment provides insights into gearbox load status, optimizes procedures through precise knowledge of operating statuses, and serves as an indicator for preventive maintenance.
