Product catalog summary

Overview of Gearbox Range
This document provides an overview of various gearbox types including planetary, bevel, and hypoid gearboxes, as well as epicyclic modules. These gearboxes are designed for industrial automation and applications requiring high torque and precision. Custom solutions are available to meet specific requirements.

Planetary Gearboxes
Planetary gearboxes are noted for increasing torque and reducing motor speed, enhancing control in electro-mechanical systems. Key features include low backlash, high torsional stiffness, and efficiency up to 98%. The RGP40 and RGP60 series are compact and integrate well with the Reliance Cool Muscle servo system, while the RGPN70 series offers higher precision and torque.

Technical Specifications
Each gearbox series has specific technical specifications such as backlash, torsional stiffness, weight, and efficiency. For example, the RGP40 series offers a backlash of less than 22 arcmin and efficiency up to 98%. The RGP60 series provides higher output torque and stiffness, suitable for more demanding applications.

Design and Customization
The document emphasizes the modular design of these gearboxes, allowing for customization and integration with various motor types. The gearboxes can be mounted in any orientation and are designed for lifetime lubrication and low noise operation.

Associated Products
Reliance Cool Muscle servo systems, couplings, and hardware are mentioned as complementary products, enhancing the functionality and integration of the gearboxes in various systems.

Specifications and Features
The document provides detailed specifications for the BE series gearboxes, including module teeth, input torque at various RPMs, and allowable rated torque. The gearboxes are supplied with a clip-on plastic cover and are designed for high torque transmission and noise reduction. The epicyclic modules offer a modular design for custom gearbox construction, suitable for heavy-duty and long-life applications.

Technical Data
The document includes tables detailing part numbers, module teeth, input torque at different RPMs, and allowable rated torque. It also provides dimensions and weights for various parts, emphasizing the modular nature of the gearboxes.

Product Overview
The gearboxes are designed for use in motorsports and sub-sea systems, with a transmission efficiency of 98% per single unit. The document highlights the load equalized structure and the ability to achieve various reduction ratios by combining standard units.

Part Number Structure
The part number structure is explained, detailing the material options (metal or plastic), input and output shaft forms, and reduction ratios. This section provides guidance on selecting the appropriate configuration for specific applications.

Custom Gearboxes
Reliance offers custom gearbox design and manufacturing, particularly for aerospace and defense markets. The document outlines the company's experience and capabilities in designing gearboxes for performance-critical applications, including environmental testing and production testing.

Accessories and Options
The document lists available accessories, such as spacer rings and output shaft options, and provides information on higher output variants and housed units. It also references additional resources for torque graphs, gearhead information, and mounting instructions.
