Product catalog summary

Technical Data Overview
The document provides comprehensive technical specifications for the REP and EP series of planetary gearboxes, covering models such as REP 075, REP 100, REP 125, REP 150, and EP 55, EP 75, EP 90, EP 120, EP 155. Key parameters include nominal and maximum input speeds, rated and maximum output torques, inertia, and noise levels.

1.0 Planetary Gearboxes REP Series
This section details the REP series, including steps, ratios, and torque specifications for different models. It features tables with values for nominal torque (T2N), maximum acceleration torque (T2A), and maximum emergency torque (T2S).

2.0 Planetary Gearboxes EP Series
The EP series is described with its characteristics and applications in machine tools, woodworking, and automation. It is available in five sizes with various output shaft and flange types. Technical data and dimensions are provided, along with motor assembly instructions.

3.0 Appendix
This section likely contains additional technical details and supplementary information.

Symbols and Units
The document includes a section on measurement units and symbols used throughout, such as nominal ratio (i), moment of inertia (J), and bearing life (Lh).

Key Specifications and Parameters

Nominal Input Speed (n1nom): Ranges from 3000 to 5000 min-1 depending on the model.
Maximum Input Speed (n1max): Up to 6000 min-1.
Rated Output Torque (T2N): Varies by model, with values provided for different steps and ratios.
Maximum Emergency Torque (T2S): Indicates the highest torque the gearbox can handle in emergency situations.
Noise Level (LpA): Less than 70 dB(A) at 3000 min-1.
Bearing Life (Lh): Estimated at 20,000 hours.

Design and Construction
The gearboxes are constructed with high-quality materials, including nitrided steel for housing, aluminum for flanges, and alloy steel for shafts and gears. Bearings are designed for long life and quiet operation.

Applications
The gearboxes are suitable for various applications, including machine tools, woodworking, printing, packaging, automation, and more.

Radial and Axial Loads on Slow Shafts
Specifications for permissible axial and radial loads on slow shafts are provided, expressed in Newtons (N), for different speeds and a bearing life of 20,000 hours. The radial load FR2 is considered at a distance equal to half the length of the slow shaft. For different distances, the new maximum permissible load FR2Y can be calculated using a formula and coefficients provided in a table.

Lubrication
EP gearboxes are supplied with long-life lubricant and are maintenance-free. It is important to specify the exact mounting position when ordering.

Symbols and Units of Measure
The document lists various symbols and their corresponding units of measure, such as nominal reduction ratio, nominal input speed, maximum input speed, intermittent output torque, maximum acceleration output torque, maximum emergency output torque, noise level, dynamic efficiency, bearing life, nominal output radial load, output axial load, torsional stiffness, standard backlash, and moment of inertia.

Moment of Inertia
The moment of inertia values are provided for different EP models (EP 55, EP 75, EP 90, EP 120, EP 155) and refer to the input shaft. The values are given for various stages and steps.

Technical Data and Dimensions
The document includes technical data and dimensions for various EP models, detailing general and output dimensions, input dimensions, and flange specifications. It also provides information on the necessary steps for mounting the motor, including the removal of the flange from the gearbox.

Technical Specifications
The document provides detailed technical specifications for various components, identified by codes such as P15, P16, etc. Each component is described with numerical values representing dimensions, capacities, and other technical parameters.

Procedures
Before mounting the motor, it is necessary to remove the flange from the gearbox. This is a critical step outlined in the assembly instructions.

Recommendations
For optimal assembly and operation, follow the specified procedures and refer to the detailed diagrams and tables provided in the document. Ensure all components are measured and installed according to the outlined specifications to maintain performance and safety standards.

Key Tables and Diagrams
The document contains numerous tables and diagrams that illustrate the dimensions and technical data of the components. These visual aids are essential for accurate assembly and understanding of the technical specifications.

Instructions for Motor Assembly
The document provides detailed instructions for the assembly of a motor onto a gearbox. Key steps include loosening the fastening screw of the clamp, removing the key from the motor shaft, cleaning contact surfaces, and ensuring the motor is fitted without impacts. The assembly screws should be tightened alternately, and the clamp screws should be tightened according to the specified torque values. All screws are supplied with a strength class of 12.9.

Application Examples
The document includes examples of applications such as the linear motion of a sliding carriage and the rotation of a revolving table. For the sliding carriage, calculations are provided for resisting torque and inertia torque, with a total torque requirement of 55 Nm. For the revolving table, the focus is on the moment of inertia and angular acceleration, with the torque requirement determined by these factors.

Formulary
The formulary section outlines the calculation of inertia and fundamental relations between torque, inertia, and angular acceleration. It also covers the relations between input and output torque and power, efficiency, and gearbox reduction ratio.

Warranty Conditions
The warranty for manufacturing defects lasts one year from the invoicing date. TRAMEC will replace or repair defective parts but will not cover additional charges for direct or indirect damages. The warranty is void if instructions are not followed or unauthorized repairs are made.

General Conditions
This catalogue supersedes all previous editions. All data listed are approximate and non-binding. The seller reserves the right to make changes without prior notice.
