摘要： 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.

摘要： Disclosed are embodiments of eccentric planetary traction drives for use in a driven turbocharger. The eccentric planetary provides torque-based loading of the traction interfaces in the traction drive. A loading planet has a larger outer diameter and has translative movement when torque is applied to the traction drive so that it is forced into a wedge gap between the turbo shaft and outer ring of the planetary drive. The torque capacity of the traction drive increases with an increase of torque demand.

摘要： An improvement of a worm gear speed reducer is provided where the output gear is substituted by a threaded chain comprised of nut-like threaded bodies mounted on the extended rods of two parallel endless chains, thus the contact surfaces of the drive screw and the threaded chain are much greater than the contact surfaces of the worm gear reducer, and thus the load capacity and wear resistance are much higher. The screw applies the driving force at the centroid of the contact surface of the threaded chain. There are three embodiments which may be a roller screw, a ball screw or a plain translation screw. With the roller screw or the ball screw there is rolling contact and thus the efficiency of the present invention is higher than that of the worm gear reducer which permits it to be used as an amplifier.

摘要： A first radial bearing and a second radial bearing are respectively disposed in two rows between the outer periphery of a pin and the inner periphery of a corresponding planet roller so as to face each other in the thrust direction. A first inner ring of the first radial bearing is fitted onto a first region of the pin by interference fit. A second inner ring of the second radial bearing is fitted onto a second region of the pin by clearance fit. The second region is closer to a carrier main body than the first region is. An elastic member is interposed between the second radial bearing and the carrier main body. The elastic member elastically presses the second inner ring in a first thrust direction.

摘要： A progressing cavity pump has a rotor that moves in an eccentric motion, and is driven by a drive shaft that rotates about a fixed axis. Various means have been used to connect the two; mostly using an intermediate shaft called a connecting rod that has a universal joint at either end. This device replaces that with two parallel plates; one with several pins protruding from it, and the other with the same number of holes in it. The holes are sized to allow the eccentric motion of the rotor. There is also a ball between the two plates to transmit loads between the plates.
