With single spur gears, a pair of gears forms a gear stage. In the event that you connect several gear pairs one after another, that is known as a multi-stage gearbox. For each gear stage, the path of rotation between your drive shaft and the result shaft is usually reversed. The overall multiplication factor 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 slow is required, because the drive torque is usually multiplied by the overall multiplication element, unlike the drive velocity.
A multi-stage spur gear could 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 tooth. From a ratio of 10:1 the driving gearwheel is extremely small. This has a poor effect on the tooth geometry and the torque that is being transmitted. With planetary gears a multi-stage gearbox is incredibly easy to realize.
A two-stage gearbox or a three-stage gearbox can be achieved by merely increasing the length of the ring gear and with serial arrangement of many individual planet stages. A planetary gear with a ratio of 20:1 can be manufactured from the average person ratios of 5:1 and 4:1, for example. Instead of the drive shaft the planetary carrier contains the sun equipment, which drives the next world stage. A three-stage gearbox is usually obtained through increasing the distance 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 could be combined, which results in a big number of ratio options 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 output shaft is always the same, so long as the ring gear or casing is fixed.
As the amount of equipment stages increases, the efficiency of the entire gearbox is reduced. With a ratio of 100:1 the efficiency is lower than with a ratio of 20:1. To be able to counteract this situation, the fact that the power lack of the drive stage can be low should be taken into thought when working with multi-stage gearboxes. This is achieved by reducing gearbox seal friction reduction or having a drive stage that is geometrically smaller, for instance. This also decreases the mass inertia, which is definitely 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 the right angle gearbox a bevel gear and a planetary gearbox are simply just combined. Here too the overall multiplication factor may be the product of the individual ratios. Depending on the kind of gearing and the type of bevel gear 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 selection of uses
