Special Design TRUSTED Cyclo Gearbox
With single spur gears, a set of gears forms a gear stage. In the event that you connect several gear pairs one after another, that is referred to as a multi-stage gearbox. For each gear stage, the path of rotation between your drive shaft and the result shaft is definitely reversed. The overall multiplication factor of multi-stage gearboxes is definitely 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 is a ratio to slow or a ratio to fast. In the majority of applications ratio to slow is required, since the drive torque can be multiplied by the entire multiplication element, unlike the drive rate.
A multi-stage spur gear could be realized in a technically meaningful method up to a gear ratio of around 10:1. The reason for this lies in the ratio of the number of teeth. From a ratio of 10:1 the traveling gearwheel is extremely little. This has a negative effect on the tooth geometry and the torque that is becoming transmitted. With planetary gears a multi-stage gearbox is extremely easy to realize.
A two-stage gearbox or a three-stage gearbox may be accomplished by simply increasing the space of the ring equipment and with serial arrangement of several individual planet stages. A planetary gear with a ratio of 20:1 could be manufactured from the average person ratios of 5:1 and 4:1, for instance. Rather than the drive shaft the planetary carrier provides the sun equipment, which drives the following world stage. A three-stage gearbox is obtained by way of increasing the space of the ring equipment and adding another world stage. A transmitting ratio of 100:1 is obtained using person ratios of 5:1, 5:1 and 4:1. Basically, all individual ratios can be combined, which results in a sizable number of ratio choices for multi-stage planetary gearboxes. The transmittable torque could be increased using additional planetary gears when performing this. The path of rotation of the drive shaft and the result shaft is usually the same, so long as the ring equipment or casing is fixed.
As the number of equipment stages increases, the efficiency of the overall gearbox is reduced. With a ratio of 100:1 the performance is lower than with a ratio of 20:1. To be able to counteract this scenario, the actual fact that the power loss of the drive stage can be low should be taken into account when using multi-stage gearboxes. That is achieved by reducing gearbox seal friction reduction or having a drive stage that is geometrically smaller, for example. This also reduces the mass inertia, which is usually advantageous in powerful 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 position gearbox a bevel equipment and a planetary gearbox are simply combined. Here too the entire multiplication factor is the product of the individual ratios. Depending on the kind of gearing and the type of bevel equipment stage, the drive and the output can rotate in the same direction.

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