Multispeed Gears

Multispeed gears are designed to be used where several constant speed segments are required. Transitions between speeds are made by using special function segments between the constant speed portions of the gearing sequence. Typically, multispeed gear pairs will have sinusoidal transitions and will not be identical. Identical input and output gearing can be achieved with elliptical transitions.
