Problem
The sowing discs over which the seed is spread must always function perfectly in this sowing machine. A total of 48 couplings in the sowing machine are responsible for this, which can separate the gearbox from the seed plate of the planter. It operates on a rotating shaft under dust and vibration conditions. The coupling is assembled on each sowing row of a planter for maize, soya and sunflowers.
Due to the difficult working conditions, however, the problem arises that the electric coupling does not always function properly. To solve the problem, it was decided to use a bronze spacer disc. However, this proved to be only a fragile and short-term solution.
