Assignee:

ORBITAL TRACTION, LTD. - Houston TX

International Classification:

F02B 63/04
F16H 1/28

US Classification:

290 1 A, 417321, 417364, 118715, 123561

Abstract:

A system has a pump with a power input, a power source and a continuously variable transmission (CVT) coupled to the power source and to the power input of the pump. The CVT transmits power from the power source to the pump. The CVT comprises a plurality of planetary members in rolling contact with an inner race and an outer race. A radial distance between the planetary members and a drive-transmitting member corresponds to a transmission ratio of the CVT.

International Classification:

F16H 59/14

F16H 59/18

US Classification:

477 41, 701 51, 701 54, 475185, 475 5, 475149

Abstract:

Systems and methods for operating a driveline system are disclosed and include a step-variable transmission. A continuously variable transmission (CVT) is coupled between an input source and the step-variable transmission. The CVT receives a first torque from the input source and outputs a second torque. The CVT has a plurality of planetary members in rolling contact with an inner race and an outer race. A radial distance between the planetary members and a drive-transmitting member corresponds to a transmission ratio of the CVT.

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

F16H 104

US Classification:

74460, 74457, 74467, 74421 R

Abstract:

An optimally finished gear has a surface roughness between approximately 5 micro-inches Ra to 10 micro-inches Ra. The reduced surface roughness, when located at the gear teeth, can reduce the maximum contact stress by more than fifty percent. Similarly, the subsurface shear stress can be reduced by approximately thirty percent. The reduced contact stress and reduced shear stress results from improved lubrication conditions between the gear teeth. Surface roughness greater than 10 micro-inches Ra results in increased contact of the surface peaks, while surface roughness lower than 3 micro-inches is too smooth to retain adequate lubrication between the gear teeth.
