right angle gearbox

Right angle gearboxes are seen as a the fact that the drive shaft and the result 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 in an axis offset.

Right angle gearboxes are realized with various kinds 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 effectiveness level, worm gears can perform a self-locking impact. With worm gears additionally it is possible to have a hollow shaft as the drive shaft.

Bevel gearboxes come with different types of gearing. Bevel gearboxes with intersecting axes are noticed 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 larger with hypoid gearboxes than with the classical bevel equipment teeth.

Bevel gearboxes may also be combined with additional gearbox types. A frequent software in this respect is the combination with a planetary gearbox, whereby the planetary gearbox can be linked upstream or downstream. This results in a wide variety of overall multiplication factors and wide selection of uses in many industrial applications.

The efficiency level of bevel gearboxes is typically lower than that of coaxial spur gearboxes, particularly compared to planetary gearboxes. This is because the bevel equipment stage generates a high degree of axial pressure and radial force, 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 running noise and the transmittable torques of classic bevel gearboxes are also lower than with single spur gear teeth. Hypoid gearboxes, however, are extremely noisy and will transmit large amounts of torque, but a considerable amount of bearing load takes place in the bevel gear stage of the gearboxes.

In summarizing, a right angle gearbox is often used when the amount of installation space in the application is limited, or an angular arrangement between your drive and the output is required by the application. Also, they are used in cases where in fact the input shaft must be hollow to be able to lead through lines or use clamping sets.
