Special Design TRUSTED Cyclo Gearbox
With single spur gears, a couple of gears forms a gear stage. In the event that you connect several gear pairs one after another, this 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 reversed. The entire multiplication aspect of multi-stage gearboxes can be 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 is a ratio to gradual or a ratio to fast. In the majority of applications ratio to slow is required, since the drive torque is usually multiplied by the entire multiplication aspect, unlike the drive rate.
A multi-stage spur gear can be realized in a technically meaningful way up to gear ratio of around 10:1. The reason for this lies in the ratio of the amount of teeth. From a ratio of 10:1 the traveling gearwheel is extremely little. This has a negative influence 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 distance of the ring equipment and with serial arrangement of a number of individual planet levels. A planetary equipment with a ratio of 20:1 can 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 equipment, which drives the next planet stage. A three-stage gearbox is certainly obtained by means of increasing the space of the ring equipment and adding another planet stage. A transmission 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 outcomes in a huge number of ratio options for multi-stage planetary gearboxes. The transmittable torque can be increased using extra planetary gears when doing this. The path of rotation of the drive shaft and the output shaft is often the same, so long as the ring gear or casing is fixed.
As the number of gear stages increases, the efficiency of the overall gearbox is reduced. With a ratio of 100:1 the effectiveness is lower than with a ratio of 20:1. In order to counteract this scenario, the fact that the power lack of the drive stage is certainly low must be taken into thought when using multi-stage gearboxes. That is achieved by reducing gearbox seal friction reduction or having a drive stage that’s geometrically smaller, for instance. 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 may also be realized by combining different types of teeth. With a right angle gearbox a bevel gear and a planetary gearbox are simply combined. Here as well the overall multiplication factor is the product of the average person ratios. Depending on the type of gearing and the type of bevel gear stage, the drive and the output can rotate in the same direction.

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