Patent number: 10704688Abstract: A radially inner race and a radially outer race for a continuously variable transmission includes a first inner race structure and a second inner race structure spaced along an axis wherein at least one of the first inner race structure or the second inner race structure is axially movable. A sun shaft is coupled to the radially inner race and planetary members in rolling contact with the radially inner race, and a torsion damping mechanism is coupled to the first inner race structure to apply torque between the first inner race structure and the sun shaft to reduce a transition amplitude during a torque impulse.Type: GrantFiled: June 1, 2017Date of Patent: July 7, 2020Assignee: Orbital Traction, Ltd.Inventors: Joseph D. Kliewer, Mark M. Koeroghlian

Patent number: 10443692Abstract: 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.Type: GrantFiled: June 25, 2018Date of Patent: October 15, 2019Assignee: Orbital Traction, Ltd.Inventors: Stuart A. Schaaf, Michael P. Bujold, Joseph D. Kliewer
