With single spur gears, a couple 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 reversed. The overall multiplication factor 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’s a ratio to slow or a ratio to fast. In the majority of applications ratio to gradual is required, because the drive torque can be multiplied by the entire multiplication aspect, unlike the drive swiftness.
A multi-stage spur gear can 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 the teeth. From a ratio of 10:1 the generating gearwheel is extremely little. This has a negative effect on the tooth geometry and the torque that is getting transmitted. With planetary gears a multi-stage gearbox is incredibly easy to realize.
A two-stage gearbox or a three-stage gearbox may be accomplished by merely increasing the space of the ring equipment and with serial arrangement of many 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 example. Rather than the drive shaft the planetary carrier contains the sun gear, which drives the next planet stage. A three-stage gearbox can be 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 person ratios could be combined, which results in a sizable number of ratio options for multi-stage planetary gearboxes. The transmittable torque can be increased using additional planetary gears when doing this. The path of rotation of the drive shaft and the result shaft is usually the same, provided that the ring gear or casing is fixed.
As the amount of gear 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 loss of the drive stage is low should be taken into consideration when working with multi-stage gearboxes. That is attained by reducing gearbox seal friction loss or having a drive stage that’s geometrically smaller, for instance. This also decreases the mass inertia, which is certainly advantageous in dynamic applications. Single-stage planetary gearboxes will be the most efficient.
Multi-stage gearboxes can also be realized by combining various kinds of teeth. With the 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 type of gearing and the kind of bevel gear stage, the drive and the result can rotate in the same path.
Advantages of multi-stage gearboxes:
· Wide range of ratios
· Continuous concentricity with planetary gears
· Compact design with high transmission ratios
· Combination of different gearbox types possible
· Wide range of uses
