A Right Angle Gearbox is defined as a set of gears, shafts and bearings that are enclosed in a housing unit. The way the gears, shafts, and bearings are arranged resemble solar system because one or more of the plant gears orbit around a sun gear.
A Right Angle Gearbox is a set of gears, shafts, and bearings that are enclosed in a housing and are arranged in a way that resemble a solar system, (thus the name Right Angle) with one or more planet gears orbiting around a sun gear. They convert input speed (typically provided by an electric motor) into a lower output speed while correspondingly creating higher torque. In other words, gear-boxes reduce RPM, turning it into power for use in low-RPM high-torque applications. Gearboxes come in different arrangements including Right Angle, bevel, cycloid, helical, harmonic, spur, and worm. Our focus here is on the Right Angle type of gear system.
The price of planetary gearboxes varies based on many factors. For backlash in the 30 arc-minute range, the cost for a gearbox might be as low as $100. For low backlash gearboxes under 5 arc-minutes they will cost quite a bit more.

The Right Angle gearbox system has 3 main components: a central sun gear, a planet carrier (carrying one or more planet gears),and an annulus (an outer ring). The central sun gear is orbited by planet gears (of the same size) that are mounted to the planet carrier. The planet gears are meshed with the sun gear. An outer ring (the annulus) has teeth facing inward that also mesh with the planet gears.
The Right Angle gearbox arrangement is an ingenious engineering design that offers many advantages over traditional gearbox arrangements. One advantage is its unique combination of both compactness and outstanding power transmission efficiencies. Typical efficiency loss in a Right Angle gearbox arrangement is only 3% per stage. This type of efficiency ensures that a high proportion of the energy being input into the Right Angle gearbox is multiplied and transmitted into torque, rather than being wasted on mechanical losses inside the Right Angle gearbox.
It's important to know certain performance specifications when selecting a Right Angle Gearbox, such as: input speed (this determines the gear ratio), output speed, and output torque required. |
