With single spur gears, a pair of gears forms a gear stage. In the event that you connect several equipment pairs one after another, that is known as a multi-stage gearbox. For each gear stage, the direction of rotation between your drive shaft and the result shaft is certainly reversed. The overall multiplication factor of multi-stage gearboxes can be calculated by multiplying the ratio of every gear stage.
The drive speed is reduced or increased by the factor of the gear ratio, depending on whether it’s a ratio to slow or a ratio to fast. In nearly all applications ratio to gradual is required, since the drive torque is definitely multiplied by the entire multiplication element, unlike the drive acceleration.
A multi-stage spur gear can be realized in a technically meaningful way up to a gear ratio of around 10:1. The reason for this lies in the ratio of the number of tooth. From a ratio of 10:1 the traveling gearwheel is extremely small. This has a poor effect on the tooth geometry and the torque that is getting transmitted. With planetary gears a multi-stage gearbox is extremely easy to realize.
A two-stage gearbox or a three-stage gearbox can be achieved by merely increasing the space of the ring gear and with serial arrangement of many individual planet levels. A planetary gear with a ratio of 20:1 could be manufactured from the individual ratios of 5:1 and 4:1, for example. Rather than the drive shaft the planetary carrier contains the sun gear, which drives the next planet stage. A three-stage gearbox is definitely obtained by means of increasing the space of the ring equipment and adding another planet stage. A tranny ratio of 100:1 is obtained using individual ratios of 5:1, 5:1 and 4:1. Basically, all person ratios could be combined, which results in a huge number of ratio options for multi-stage planetary gearboxes. The transmittable torque could be increased using extra planetary gears when doing this. The direction of rotation of the drive shaft and the result shaft is always the same, so long as the ring gear or casing is fixed.
As the number of equipment stages increases, the efficiency of the overall gearbox is decreased. With a ratio of 100:1 the efficiency is lower than with a ratio of 20:1. In order to counteract this situation, the actual fact that the power lack of the drive stage is certainly low should be taken into factor when using multi-stage gearboxes. That is attained by reducing gearbox seal friction loss or having a drive stage that is geometrically smaller, for example. This also decreases the mass inertia, which is certainly advantageous in powerful applications. Single-stage planetary gearboxes will be the most efficient.
Multi-stage gearboxes can also be realized by combining various kinds of teeth. With a right angle gearbox a bevel equipment and a planetary gearbox are simply just combined. Here too the entire multiplication factor may be the product of the individual ratios. Depending on the kind of gearing and the kind of bevel equipment stage, the drive and the output can rotate in the same direction.

Benefits of multi-stage gearboxes:
· Wide range of ratios
· Continuous concentricity with planetary gears
· Compact style with high transmission ratios
· Combination of different gearbox types possible
· Wide selection of uses
