Abstract
The speed change gear transmits motion between two shafts (11,12) comprising at least two rotatable cogwheels (2), set radially in guides at a distance from the axis of rotation of a main support plate (1). The support plate is connected to one of the shafts (11) and the cogwheels engage a link-roller chain (4) that provides a rolling track for the cogwheels. In operation, the radial position of the cogwheels can be continuously varied in relation to the axis of rotation of the main support plate and allows the circumference of rotation of the rolling track to be varied so as to produce different output angular velocities with an equal input angular velocity. This allows the use of normal chain driven gears and rolling track to be used to transmit considerable tangential forces synchronously without slip between the individual components.
