Right angle gearboxes are characterized by the fact that the drive shaft and the output shaft are arranged at an angle of 90 degrees. According to the gearbox type, the axes can intersect in a plane or cross on two parallel planes, which results within an axis offset.

Correct angle gearboxes are noticed with different types of gear teeth or a combination of different gearing types. The most popular single-stage gearbox types are bevel and worm.

Due to the high solitary stage ratios and the reduced performance level, worm gears can perform a self-locking impact. With worm gears additionally it is possible to get a hollow shaft as the drive shaft.

Bevel gearboxes include various kinds of gearing. Bevel gearboxes with intersecting axes are recognized using bevel gearing with straight, helical or spiral the teeth. Hypoid gearboxes possess helical bevel gearing with which the axes cross with an axis offset. The bandwidth of technically practical ratios with which the bevel gear stage could be realized is bigger with hypoid gearboxes than with the classical bevel equipment teeth.

Bevel gearboxes can also be combined with additional gearbox types. A regular program in this respect may be the mixture with a planetary gearbox, whereby the planetary gearbox can be linked upstream or downstream. This outcomes in an array of overall multiplication factors and wide range of uses in lots of industrial applications.

The efficiency degree of bevel gearboxes is normally lower than that of coaxial spur gearboxes, particularly in comparison to planetary gearboxes. That is because the bevel equipment stage generates a high degree of axial force and radial power, which needs to be absorbed by appropriate bearings. This increases the power loss, which is particularly significant in the drive stage of the gearbox.

The working noise and the transmittable torques of classic bevel gearboxes are also less than with single spur equipment teeth. Hypoid gearboxes, however, are incredibly noisy and may transmit huge amounts of torque, but a considerable amount of bearing load happens in the bevel equipment stage of the gearboxes.

In summarizing, the right angle gearbox is generally used when the quantity of installation space in the application is bound, or an angular arrangement between the drive and the output is required by the application. Also, they are used in instances where the input shaft must be hollow to be able to business lead through lines or use clamping sets.
