Special Design Widely Used Cyclo Gearbox
With single spur gears, a set of gears forms a gear stage. If you connect several gear pairs one after another, this is known as a multi-stage gearbox. For each gear stage, the direction of rotation between the drive shaft and the output shaft is definitely reversed. The entire multiplication aspect of multi-stage gearboxes is usually calculated by multiplying the ratio of each 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 slower is required, because the drive torque is multiplied by the overall multiplication aspect, unlike the drive quickness.
A multi-stage spur gear could be realized in a technically meaningful way up to a gear ratio of approximately 10:1. The reason for this lies in the ratio of the amount of teeth. From a ratio of 10:1 the driving gearwheel is extremely little. This has a negative effect on the tooth geometry and the torque that is being 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 basically increasing the length of the ring equipment and with serial arrangement of a number of individual planet stages. A planetary gear with a ratio of 20:1 can be manufactured from the individual ratios of 5:1 and 4:1, for example. Instead of the drive shaft the planetary carrier provides the sun gear, which drives the following world stage. A three-stage gearbox is certainly obtained by way of increasing the space of the ring equipment and adding another planet stage. A transmitting ratio of 100:1 is obtained using individual ratios of 5:1, 5:1 and 4:1. Basically, all person ratios can be combined, which results in a large number of ratio options for multi-stage planetary gearboxes. The transmittable torque can be increased using additional planetary gears when performing this. The path of rotation of the drive shaft and the output shaft is generally the same, so long as the ring equipment or casing is fixed.
As the number of gear stages increases, the efficiency of the entire gearbox is decreased. With a ratio of 100:1 the performance is lower than with a ratio of 20:1. In order to counteract this scenario, the actual fact that the power lack of the drive stage can be low must be taken into consideration when working with multi-stage gearboxes. That is achieved by reducing gearbox seal friction loss or having a drive stage that is geometrically smaller, for instance. This also reduces the mass inertia, which is advantageous in dynamic applications. Single-stage planetary gearboxes will be the most efficient.
Multi-stage gearboxes can also be realized by combining different types of teeth. With a right angle gearbox a bevel equipment and a planetary gearbox are simply combined. Here as well the overall multiplication factor may be the product of the average person ratios. Depending on the kind of gearing and the type of bevel equipment stage, the drive and the result can rotate in the same direction.

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