Abstract:
Apparatus for translating motion from a first to a second velocity, the apparatus comprisingthree drive devices, including a conjugate pair of the devices and a motion translating device, mounted about a common axis, having an input and output rotatable about the common axis,one of the devices translating motion of a first of the devices at a first velocity to motion of a second of the devices at a second velocity, the first of the devices coupled to an input of the translating devices and the second of the devices coupled to an output of the translating device, whereby motion of the first of the devices can be translated to motion of the second of the devices,wherein a first of the pair of conjugate devices comprises a drive cam and the second of the pair of devices comprises a driven cam,wherein one of said cams each forms a rise flank and a fall flank, wherein a flank is formed having a main drive segment formed according to a first function and at least one transition segment formed according to a second function.
