Right angle gearboxes are characterized by the fact that the drive shaft and the output shaft are organized at an angle of 90 degrees. With respect 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 realized with different types of gear teeth or a mixture of different gearing types. The most popular single-stage gearbox types are bevel and worm.

Because of the high solitary stage ratios and the low efficiency level, worm gears can achieve a self-locking impact. With worm gears additionally it is possible to possess 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 directly, helical or spiral 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 can be realized is bigger with hypoid gearboxes than with the classical bevel equipment teeth.

Bevel gearboxes can also be combined with various other gearbox types. A frequent program in this respect may be the mixture with a planetary gearbox, whereby the planetary gearbox could be connected upstream or downstream. This results in an array of overall multiplication elements and wide selection of uses in many industrial applications.

The efficiency level of bevel gearboxes is normally less 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 drive and radial push, which has to be absorbed by appropriate bearings. This increases the power loss, which is particularly notable in the drive stage of the gearbox.

The running noise and the transmittable torques of classic bevel gearboxes are also lower than with single spur equipment teeth. Hypoid gearboxes, on the other hand, are extremely noisy and may transmit large amounts of torque, but a considerable amount of bearing load occurs in the bevel equipment stage of these gearboxes.

In summarizing, the right angle gearbox is at all times used when the amount 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 situations where the input shaft needs to be hollow in order to lead through lines or make use of clamping sets.
