Power transfer through the Candy Differential begins at the input shaft with a spiral-bevel drive gear affixed at its inboard end. This drive gear transfers power at right angles through the idler gears, which are pinned to the carrier, and then to the output drive gear and shaft. The input and output shafts incorporate a patented backbone support system so that overhung loads are not deflected into the gear mesh. When the carrier is held stationary, the power transfer results in a 1:1 ratio transmission with counter-rotating shafts. Applying a rotation to the control shaft causes the carrier to rotate intermittently or continuously in one direction or the other. This rotation changes the position of the bevel gear assembly about the main shaft center line, causing a differential action between input and output elements. Since this control action is independent of the drive function, phase adjustments can be made while the Candy Differential is in motion providing precise position or speed control.
