| 074828000 | ALTERNATING-MOTION DRIVEN DEVICE WITH MEANS DURING OPERATION TO ADJUST STROKE | 10 |
| 20080271565 | RESISTANCE WELDING GUN WITH INDEPENDENT ACTUATORS - An actuator assembly for a welding gun is provided that has at least three positions in the example. The actuator assembly includes separate working and retract actuators. The working actuator includes a working rod movable between first and second positions. The retract actuator includes a retract rod independently movable relative to the working rod between third and fourth positions. The retract actuator is external to and non-concentrically arranged relative to the working actuator in the example shown. Actuation of the working and retract actuators is coordinated to provide at least three positions while enabling the actuators to be changed or modified independently from one another. A latching device is configured to selectively interlock the working and retract actuators to one another automatically in response to movement the working rod from the first position to the second position. | 11-06-2008 |
| 20160136788 | WORK APPARATUS - An objective of the invention is to provide a work apparatus in which the maximum value of the force acting on a work object is unchanged even when the size of the object varies, the work apparatus not exerting force in excess of a prescribed value. The work apparatus is provided with a first member ( | 05-19-2016 |
| 074829000 | Constant length stroke with means to displace end limits | 3 |
| 20100229679 | Stepless positioning structure for telescopic tube - A stepless positioning structure for a telescopic tube includes a spindle, a spring, an elastic sleeve, a ball socket, and a plurality of balls. The elastic sleeve has a first central through hole, an inner end fixed to an inner end of an inner tube, and an outer end provided with an engaging section. The engaging section has a reduced portion at an outer end thereof. The ball socket is disposed in an outer tube, and has a second central through hole and a plurality of chambers formed on a side wall thereof. The chambers interconnect with the second central through hole of the ball socket. Either of upper and lower ends of each chamber is formed with a curve surface. The balls are accommodated in the chambers of the ball socket. The spindle is inserted through the spring, the first central through hole of the elastic sleeve, and the second central through hole of the ball socket. The spring holds against an inner end of the spindle and the elastic sleeve, respectively. An outer end of the spindle is secured to an outer end of the ball socket. The present invention achieves a stepless adjustment and provides a confinement function to the inner and outer tubes. This is convenient for operation. | 09-16-2010 |
| 20170235327 | Force feedback handle device with a degree-of-freedom and working method thereof | 08-17-2017 |
| 074830000 | Cyclical displacement responsive to the alternating-motion | 1 |
| 20090000424 | SPINDLE OR WORM DRIVE FOR ADJUSTING DEVICES IN MOTOR VEHICLES - A spindle or worm drive for adjusting devices, especially seat adjustment devices, window lifters and sliding roofs, in motor vehicles. The drive includes a fixed spindle or relatively fixed toothed rack which is secured to the second of the two parts. The gear elements are mounted in a housing which includes at least two plates that can be secured to each other by plug-in connectors. The connectors are also configured as supporting joints that absorb the forces of the gear. | 01-01-2009 |
| 074831000 | Stroke adjustable to zero and/or reversible in phasing | 5 |
| 20100229680 | CONTINUOUSLY VARIABLE TRANSMISSION MACHINE - A ratcheting-type, rotor controlled, continuously variable transmission machine wherein the circumferential length of a cross-sectional profile of a body of the rotor is substantially constant, and the maximum positive swivel angle of the body is substantially equal in magnitude to the maximum negative swivel angle of the body. | 09-16-2010 |
| 074837000 | Crank pin drive, shiftable pin | 3 |
| 20100011906 | Adjustment Mechanism for Strokeadjustable Reciprocating Fluid Machine - An adjustment mechanism for a stroke-adjustable reciprocating fluid machine comprising a crank shaft which is rotatable about a rotational axis, and a rotatable eccentric crank eccentrically supported about the crank shaft in a bearing, the crank having a crank centre, and the crank centre being adjustable relative to the rotational axis between a largest and a smallest radial distance thereto, and an adjustment motor connected to the drive of the fluid machine also being connected to the crank via a third angular gear which cooperates with a fourth angular gear, the fourth angular gear being connected to an adjustment output axle having its centre on the rotational axis and being connected to the crank by means of an adjustment sleeve, the crank shaft being connected to the main drive shaft of the fluid machine via a first angular gear which cooperates with a second angular gear. | 01-21-2010 |
| 20100199805 | CONTINUOUSLY VARIABLE TRANSMISSION - This invention provides continuously variable transmissions and associated powertrains and automotive transmission systems. Included among the transmission systems provided are efficient transmissions for employing regenerative braking. | 08-12-2010 |
| 20100229681 | CONTINUOUSLY VARIABLE TRANSMISSION - Disclosed is a continuously variable transmission. The continuously variable transmission includes a housing to which an input shaft is rotatably mounted to input power, an output section outputting the power transferred from the input shaft to the outside or receiving a load from outside, a torque change section provided between the input shaft and the output section to change the torque of the power transferred from the input shaft or the output section, and a link device disposed between the output section and the torque change section and eccentrically connected to the torque change section to transfer rotational power to the output section or receive a load from the output section by upward and downward reciprocal movements thereof. | 09-16-2010 |
| 074838000 | Cam and follower drive | 1 |
| 074839000 | Axial-type cam (e.g., wabbler type) | 1 |
| 20090031853 | COMBINATION GEAR, DETACHABLE UNIT, AND IMAGE FORMING APPARATUS USING THESE - A combination gear having a simple structure is provided at low cost without increasing a number of components. In at least two gears adjacent in an axial line direction and having a same rotation direction, three engaging portions arranged in a regular triangle are formed at an end of one of the adjacent gears and a regular triangle engaging hole is formed at an end of another gear. The engaging portions and the engaging hole fit together with play remaining, and when one of the gears rotates, the three engaging portions and three surfaces of the engaging hole engage such that the other gear rotates coaxially, and when rotation stops, the engaging portions and the engaging hole move in a direction orthogonal to the axial line by a play amount and become eccentric. | 02-05-2009 |
