Coaxial Gearbox

With a coaxial gearbox, also referred to as an inline gearbox, the drive shaft and the output shaft are on the same rotation axis. Coaxial gearboxes are usually in the form of spur gears. Spur gears come in different versions.

With a single spur gear the axes of the individual spur gears are parallel to each other and fixed. The direction of rotation of the input shaft and the output shaft is specified by the number of gear pairs, and can be in the same direction or in the opposing directions.

Even if single spur gears are not coaxial gearboxes in principle, concentricity can be achieved using two pairs of gear wheels with a total of four gearwheels. Two of the gearwheels are arranged parallel on one axis when doing this.

One special type of coaxial gearbox is the planetary gearbox. Unlike a single spur gear, with a planetary gear not all axes are fixed. A spur gear also has internal teeth. With a planetary gearbox, several spur gears run between a gear with internal teeth and a gear with external teeth on a concentric orbit. This is how planetary gears acquired their name. The coaxial arrangement of the input shaft and the output shaft is already given by the specific design with these coaxial gearboxes.

Another special feature of the planetary gearbox is that not all of the spur gears have to rotate around their own axis in order to transmit a torque. The spur gear with the internal teeth is usually fixed, which results in the drive shaft and the output shaft rotating in the same direction.

Compared to single spur gears, planetary gearboxes have an extremely good power density. This achieved by the fact that the torque can be distributed to the orbiting spur gears and therefore several tooth engagements. This means that an extremely compact design and extremely high efficiency can be achieved. Multi-stage ratios can also be achieved by means of single serial arrangement in the same spur gear with internal teeth. The overall multiplication factor results from the product of the individual rations of each planet stage.

The conversion of the speed and the torque takes place in the same way as a single spur gear. For example, with a gear ratio of 10:1, the torque is increased by a factor of 10 and the speed is reduced by the same factor.

 

The advantages of coaxial gearboxes:

  • Coaxial arrangement of input shaft and output shaft
  • Extremely high efficiency
  • Extremely high power density
  • Compact design
  • Suitable for a wide range of applications
  • Easy to realize multi-stage gearboxes and therefore high transmission ratios
