A gear system is one involved in the transmission of motion. The two toothed wheels assure a driving force without slippage. In these four systems, the driving wheel (at top) turns at a constant speed.
- First case: the "Maltese Cross " system transforms the contiunuous rotation into discontinuous motion: this is a turn counter.
- Other cases: the variable speed of the lower wheel is determined by the wheel's geometry.
- To illustrate the possibilities of varying the rotational speed in a gear system.
- To lllustrate the kinematics of rotating objects.
In all cases, the upper wheel is the driving wheel, which turns at a constant speed.
A simple gear system is made of two circles: the transmission ratio for speed is a function of the ratio of…
