Planetary gear free of backlash

Construction pin

A clamped planetary stage is difficult to mount since its cog wheels bounce outwards. The planetary stage must be applied in the internal gear so that an assembly is possible. In this case one can make a drilling through the middle of the axis with the help of an assembly pin. The assembly pin can be put through the planetary gear and through the sun gear. In this way it is simpler to assembly the stage via an inserting through the hollow wheel and to avoid a slipping off of the cog wheels. In order that the cog wheels, which lie next to each other in different levels, do not lock, a washer is put between the different levels.

The dimensioning

The first dimensioning of the joints can take place with a self-developed calculation module and be optimized via FEM.
