Abstract: An infinitely variable traction roller transmission with traction rollers arranged between, and in engagement with, opposite toric discs for the transmission of motion therebetween includes traction roller support trunnions pivotally mounted in a transmission housing which has partially cylindrical housing cavities formed behind the trunnions, the trunnions having a hydraulic support structure including a seal plate having a curved face in engagement with the partially cylindrical housing and an opposite flat face adjacent a hydrostatic support cavity in said trunnions which permits friction-free sliding movement and pivoting of the trunnions for adjustment of the transmission ratio.

Abstract: A traction roller transmission having a number of traction rollers disposed in an annular space formed between a sun roller structure rotatable with one shaft and a traction ring structure surrounding the sun roller. The traction rollers are rotatably supported and the traction rollers or the traction ring structures are mounted for movement with another shaft. The traction rings or sun roller structures have Belleville type discs disposed between cam structures such that a torque transmitted through the transmission forces the traction rings toward each other for firm engagement of the traction rollers with the traction ring and the sun roller structures.

Abstract: A rotary motion transmitting device having oppositely disposed toric discs mounted on its input and output shafts. Motion transmitting rollers are frictionally engaged between the toric discs for transmitting motion from one toric element to the other and tension sheets extend between opposite rollers to balance forces exerted on the rollers. Pivotal roller supports are interconnected by correlating means which point limited independent pivotal movement of the roller supports while resiliently forcing the supports into the same angular positions. Also means are provided for controlling the transmission ratio such that the output torque assumes a desired value.

Abstract: A traction roller transmission having a number of traction rollers disposed in an annular space formed between a sun roller rotatable with one shaft and traction rings surrounding the sun roller. The traction rollers are rotatably supported and mounted for movement with another shaft and the traction rings are slightly conical and held in position by cam structures such that a torque transmitted through the transmission forces the conical traction rings toward each other so as to cause firm engagement of the traction rollers with the traction rings and the sun roller. Springs are disposed between the traction rings to provide for return of the traction rings when the torque transmitted through the transmission is reduced.

Abstract: A hydrostatic axial thrust bearing has a load member supported on a support member by pressurized fluid supplied to a cavity providing a hydrostatic bearing area between the two members in a plane normal to the axis of the thrust bearing and including means for varying the effective bearing area to permit the bearing to adjust to large variations in load.BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention relates to a hydrostatic axial thrust bearing which includes means for varying the hydrostatic bearing area for adjustment to the bearing load.2. Description of the Prior ArtA hydrostatic axial thrust bearing consists of a support member and a load member disposed adjacent to the support member with a cavity between the two members to which cavity pressurized fluid is supplied for supporting the load member on the support member. The pressurized fluid supplied to the cavity leaves the cavity through a land area formed around the cavity between the load and support members.
