The present invention is related to a traction drive synchronous governor and a multi-axis drive gearbox with the same, and includes a governor chamber and a speed change gear chamber. The present invention uses the synchronous governor that is deposited in the governor chamber to transmit the power of engine to an output set of the gearbox. The governor has multiple wheel assemblies between an input element and an output element in a planetary arrangement. The wheel assemblies are pushed by the output element to axially move to abut the input element to provide a power transmitting effect. At the same time, the shaft of each drive set in the speed change gear chamber is arranged in parallel at unequally spaced intervals and are surrounded by the output shaft as a center, and this may increase the number of gears of the gearbox in a limited space.

Disclosed are embodiments of thrust absorbing planetary traction drives that utilize roller-shaft traction interfaces that are slanted to absorb thrust created on a turbo shaft by a turbine or compressor. Slanted traction surfaces on the sun portion of the turbo shaft are slanted inwardly so that the turbo shaft remains centered in the planetary traction drive. Either double roller planets or single roller planets can be used to absorb thrust in the axial direction of the turbo shaft. Various curved and slanted surfaces can be utilized to create traction interfaces that hold and stabilize the turbo shaft both axially and radially.

A high speed ratio drive system is formed of planet rollers, each having varying diameter, an outer fixed ring in contact with one diameter of the planet rollers, and an outer drive ring in contact with another diameter of the planet rollers. An inner drive element is provided by a sun drive roller in contact with the planet rollers or by a planet carrier. Preferably the system has an axial reflective symmetry minimizing twisting forces on the planet rollers.

A power transfer apparatus and a method of configuring and assembling a power transfer apparatus. The power transfer apparatus includes a continuously variable transmission having a plurality of planets and a plurality of planet spindle assemblies, each one of the plurality of spindle assembly configured to rotatingly support one of the plurality of planets. Each of the spindle assemblies includes a spindle disposed in a channel of one of the plurality of planets. The spindle includes a first end in contact with an input disc and a second end in contact with an output disc. A first and second bearing are respectively located at recesses formed in the spindle. Each of the first bearing and second bearing are in contact with the interior surface of the channel of the planet to provide rotational support thereof. The power transfer apparatus provides improved assembly, performance and reliability.
