With single spur gears, a set 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 direction of rotation between your drive shaft and the result shaft is reversed. The overall multiplication aspect of multi-stage gearboxes is certainly calculated by multiplying the ratio of each gear stage.
The drive speed is reduced or increased by the factor of the apparatus ratio, depending on whether it’s a ratio to sluggish or a ratio to fast. In nearly all applications ratio to sluggish is required, because the drive torque is multiplied by the entire multiplication factor, unlike the drive rate.
A multi-stage spur gear can be realized in a technically meaningful method up to a gear ratio of around 10:1. The reason for this is based on the ratio of the amount of the teeth. From a ratio of 10:1 the generating gearwheel is extremely small. This has a poor influence on the tooth geometry and the torque that’s getting 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 merely increasing the distance of the ring gear and with serial arrangement of a number of individual planet levels. 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. Instead of the drive shaft the planetary carrier contains the sun equipment, which drives the following planet stage. A three-stage gearbox is definitely obtained through increasing the length of the ring gear and adding another world stage. A tranny ratio of 100:1 is obtained using individual ratios of 5:1, 5:1 and 4:1. Basically, all individual ratios could 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 carrying out this. The path of rotation of the drive shaft and the output shaft is often the same, so long as the ring equipment or housing is fixed.
As the number of gear stages increases, the efficiency of the entire gearbox is decreased. With a ratio of 100:1 the efficiency is leaner than with a ratio of 20:1. In order to counteract this circumstance, the fact that the power lack of the drive stage can be low should be taken into thought when using 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 reduces the mass inertia, which is advantageous in dynamic applications. Single-stage planetary gearboxes will be the most efficient.
Multi-stage gearboxes may also be realized by combining various kinds 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 type of gearing and the type of bevel gear stage, the drive and the result can rotate in the same path.
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
