Right Angle Bevel Gearboxes

Our right angle Bevel gearbox lineup includes shaft to shaftshaft to borebore to bore, 2-shaft, 3-shafthigh ratio, counter rotating output, and low profile models. We offer several options, including metric and inch shafts, hollow bore units, and gearboxes with one hollow bore and one solid shaft. Hollow bore right angle gearboxes can be fitted with shafts that are larger or smaller in diameter as they exit the gearbox.

Ondrives.US bevel gearboxes feature a sturdy aluminum housing and hardened steel gears to make them lightweight and durable. Most of our gearboxes are supplied with Spiral cut bevel gears which offer a smoother, quieter, and stronger performance.

For specialized applications, we also offer counter rotating bevel gearboxes with an additional gear and a split T-shaft that allows the output shafts to rotate in opposite directions, simultaneously and on the same axis. View our catalog to view specifications for all our bevel gearbox products.


Understanding Bevel Gearbox Ratios

Right-angle bevel gearboxes that have a 1:1 gear ratio are often call Miter gearboxes. All higher ratio boxes are called Bevel gearboxes. The high end of bevel gearbox ratios rarely exceeds 4:1 due to the size of the larger bevel gear. However, our high ratio right angle gearboxes are unique: these heavy-duty boxes incorporate additional gearing to accomplish higher ratios than can be found in other right angle gearboxes.
Standard ratios for our High Ratio bevel gearbox units include 6:1, 12:1, 18:1, and 24:1. Custom gear ratios are available upon request.

Standard and Custom Right Angle Gearboxes

Standard right-angle gearboxes come in numerous configurations to meet your application requirements. Our Buyer’s Guide outlines the ten points to consider when choosing a bevel gearbox. Another valuable reference, Inertia and the Use of Inertia Figures, has a formula for dealing with inertia in gearbox selection.

With the understanding that every application is unique, we can modify stock gearboxes or engineer custom right angle gearboxes to your OEM specifications. Custom capabilities include working from your drawing, developing a custom bevel gearbox design based on your requirements, or reverse engineering an existing, obsolete product.
