Product catalog summary

Technical Data Overview
The document provides comprehensive technical specifications for the REP and EP series of planetary gearboxes, detailing models such as REP 075, 100, 125, 150, and EP 55, 75, 90, 120, 155. It includes information on steps, nominal and maximum input speeds, torque values, and other mechanical properties.

Measurement Units and Symbols
This section explains the symbols and measurement units used, such as torque (T2N, T2A, T2S), speed (n1nom, n1max), and inertia (Jmin, Jmax). Definitions for terms like axial and radial loads, efficiency, and temperature limits are also provided.

REP Series Planetary Gearboxes
The REP series is designed for applications in machine tools, woodworking, printing, and automation, available in four sizes with various output shaft and flange options. Constructed from high-quality materials, these gearboxes ensure durability and precision.

EP Series Planetary Gearboxes
Similar to the REP series, the EP series offers a range of sizes and configurations suitable for different industrial applications, focusing on performance metrics like torque and speed.

Appendix
Includes additional technical data such as thermal checks, backlash, and lubrication instructions, along with guidelines for selecting the appropriate gearbox based on operational requirements.

Specifications
The document outlines duty coefficients for utilization (KU) and intermittent duty (KM) using specific formulas. Key parameters include maximum acceleration torque at output (T2A), rated intermittent allowable torque (T2N), maximum acceleration torque of the motor (T1AMOT), reduction ratio (i), cycle factor (fc), and dynamic efficiency (Rd).

Procedures
For intermittent duty, specific equations must be verified, including comparisons of maximum allowed input speed with the maximum rotation speed reached by the application. Similar checks are required for continuous duty to ensure operational parameters are within specified limits.

Standards
Tables for calculating cycle factors (fc) based on cycles per hour (Zh) and utilization factors (fu) based on the ratio of running time to cycle time are provided. Thermal capacity limits for power and torque ensure gearbox temperature does not exceed 95°C.

Recommendations
For applications requiring higher torque/power than permitted, calculate the maximum duration of operation (tmax) to prevent exceeding the temperature limit. Guidelines for calculating average torque and speed if the operation cycle varies over time are also provided.

Key Data from Tables
Tables provide values for thermal capacities, loadless friction power, and loss of heat coefficients based on gearbox size, number of reduction stages, and input rotation speed, critical for ensuring safe thermal operation.

Critical Information
Ensure all operational parameters, such as torque, speed, and temperature, are within specified limits to maintain gearbox efficiency and longevity. Utilize provided tables and formulas to calculate necessary factors and verify compliance with standards.

Technical Specifications
Detailed specifications for components such as output shafts, input dimensions, and flanges are provided, including measurements and standards for different models like AU19, AU22, AU25, and AU32.

Procedures
Instructions for motor assembly emphasize removing the flange from the gearbox before mounting the motor, including steps like loosening screws, removing keys, cleaning surfaces, and securing the motor to the gearbox.

Standards and Norms
Specifications include nominal and maximum input speeds, rated intermittent output torque, maximum acceleration output torque, and maximum emergency output torque, along with noise levels, dynamic efficiency, bearing life, radial and axial load capacities, torsional rigidity, and maximum backlash.

Recommendations
Ensure proper alignment and securing of components during assembly to prevent damage and ensure optimal performance.

Key Data from Tables
Tables provide detailed dimensions and specifications for various components, including input and output shafts, flanges, and torque values, with key data on nominal ratios, input speeds, and torque capacities for different stages and configurations.

Appendix: Examples of Applications

Sliding Carriage: Involves the linear movement of a table using a chain with a transmission reduction ratio of i=1. The carriage, with a mass of 200 kg and a diameter of 0.1 m, needs to accelerate to a maximum speed of 0.6 m/s in 0.2 seconds. The gearbox reduction ratio is i=20, and the resisting force is 500 N. Calculations for resisting torque (TRES) and inertia torque (TIN) are provided, resulting in a total torque (T2) of 55 Nm, crucial for motor selection.
Revolving Table: Requires the rotation of a cylindrical table with a mass of 20 kg and a radius of 0.5 m. The table must accelerate from 0 to 300 rpm in 0.3 seconds. The gearbox reduction ratio is i=20. The resisting torque is negligible compared to the inertia torque, which is calculated to determine the appropriate motor torque.

Formulary

Includes calculations for inertia (J), fundamental relations between torque (T), inertia (J), and angular acceleration (aa), as well as relations between input/output torque and power, efficiency, and gearbox reduction ratio.

General Warranty Conditions

The warranty for manufacturing defects lasts one year from the invoice 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 in the use and maintenance manual are not followed or if unauthorized repairs or modifications are made.

Revisions

Details changes made in various years, including modifications to dimensions and angular backlash.
