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 the drive shaft and the result shaft is definitely reversed. The overall 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 apparatus ratio, depending on whether it’s a ratio to sluggish or a ratio to fast. In nearly all applications ratio to gradual is required, because the drive torque is definitely multiplied by the overall multiplication factor, unlike the drive quickness.
A multi-stage spur gear can be realized in a technically meaningful way up to gear ratio of approximately 10:1. The reason behind this lies in the ratio of the amount of the 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’s 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 simply increasing the length of the ring gear and with serial arrangement of a number of individual planet phases. A planetary gear with a ratio of 20:1 can be manufactured from the individual ratios of 5:1 and 4:1, for instance. Instead of the drive shaft the planetary carrier provides the sun gear, which drives the next world stage. A three-stage gearbox is usually obtained by way of increasing the length 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 huge number of ratio options 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 result shaft is generally the same, provided that the ring equipment or housing is fixed.
As the number of equipment stages increases, the efficiency of the entire gearbox is reduced. With a ratio of 100:1 the performance is leaner than with a ratio of 20:1. In order to counteract this situation, the actual fact that the power lack of the drive stage can be low must be taken into factor 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 decreases the mass inertia, which is 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 equipment and a planetary gearbox are simply combined. Here too the overall multiplication factor may be the product of the average person ratios. Depending on the kind 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 range of ratios
· Constant concentricity with planetary gears
· Compact style with high transmission ratios
· Combination of different gearbox types possible
· Wide selection of uses
