Gearboxes - Introduction

The Reliance catalogue gearbox range includes planetary, bevel and hypoid gearboxes, which provide housed, modular solutions, as well as an epicyclic gear module, which can be used in single or multiple stacks to build a customised gearbox.

We also provide design, manufacturing, assembly and test services to create custom gearbox solutions, designed to specification.

Gearboxes Come In The Following Styles

Planetary

Planetary gearboxes give the ability to increase the torque and lower the speed of an electric motor, such as a stepper motor, thereby transforming the power and improving control of an electro-mechanical system.

The Reliance planetary gearboxes offer low backlash, high torsional stiffness, and high levels of efficiency, suitable for industrial automation applications.

Designed specifically to suit NEMA 17 and NEMA 23 motors. They are ideally suited to work with the Reliance Cool Muscle intelligent servo system in high torque applications where positional feedback is important.

We offer 3 plantary gearboxes - the RGP40 and RGP60 provide a compact solution for integration with Reliance Cool Muscle, whilst the RGPN70 is for high precision, higher stiffness, higher torque and lower backlash applications.

Hypoid & Bevel

Reliance Bevel and Hypoid Gearboxes provide an economic, space saving solution for right angle motion in a restricted space envelope. There are 3 types of gearbox available from Reliance.

Epicyclic Modules

Reliance Epicyclic Modules are available in ratios of 3:1, 4:1 and 5:1. Their unique design allows the units to be stacked together providing higher ratios. It is ideal for heavier duty, or long-life, torque amplification, and speed reduction applications; the units have been used successfully in sealed sub-sea applications and in motorsports mechanisms.
