carved arolla pine wood
cm 75 x 75 x 75
Description:
This is a mechanism with orthogonal axes comprising a pinion with orthogonal teeth engaging a toothed wheel. The system can be used to reduce speed. In his pages of notes, Leonardo stressed the fact that helical teeth last longer than normal ones, because their surface-tooth contact is greater.
