Stepped up transmission

We design gears particularly for stepped up trasnmission. The toothing is specifically designed to place the area of operation behind the point of contact in order to achieve sliding friction. Depending on design, gears with high reductions can easily be produced with a ratio ranging from i = 1 : 1 to i = 1 : 200 or even significantly higher.

Both, outer and inner toothing can be accomplished. In some extreme cases, the advanced design does not tolerate small defects. The gear box may be blocked.

Usally, the area of action is behind the point of contact to a great extend for involute toothing (picture by Claudio Rocchini).
