摘要： A method for controlling back clearance of a motion transmission apparatus, is capable of controlling the generation, reduction and even elimination of a back clearance of a motion transmission apparatus to meet different needs. The motion transmission apparatus comprises: a first electric motor, a second electric motor, and a toothed member engaged with the first and second toothed drive members, when the toothed member needs to be precisely positioned, the back clearance between the second electric motor and the toothed member at different positions of the toothed member will be controlled according to the torque change, so as to consequently change a position offset of the second electric motor with respect to the first electric motor, when the toothed member doesn't need to be precisely positioned, the second electric motor shouldn't be controlled.

摘要： A positioning device without backlash includes a table and at least one gear operatively associated with the table. At least one worm gear is connected to the gear and the gear is driven in a desired direction with a primary motor and a synchronized slave motor. The synchronized slave motor is then reversible to remove the backlash in the positioning device thereby permitting an actual position to correspond with a dialed-in position.

摘要： Embodiments of the present invention are directed to gear transmission apparatus that are configured to largely eliminate the cogging effects and to reduce the backlash effects. In one embodiment, a transmission apparatus comprises a follower gear, a first drive gear set coupled with the follower gear to drive the follower gear, and a second drive gear set coupled with the follower gear to drive the follower gear. The first drive gear set includes at least one gear, and the second drive gear set includes at least one gear. A first motor is coupled with the first drive gear set. The first motor includes a first rotor having a plurality of poles which are movably disposed relative to a plurality of magnets. A second motor is coupled with the second drive gear set. The second motor includes a second rotor having a plurality of poles which are movably disposed relative to a plurality of magnets. The disposition of the poles relative to the magnets of the first motor is out of phase with respect to the disposition of the poles relative to the magnets of the second motor. The first motor produces a torque that varies between a first maximum level and a first minimum level, and the second motor produces a torque that varies between a second maximum level and a second minimum level. The torque of the first motor and the torque of the second motor do not reach the first and second maximum levels, respectively, at the same time and do not reach the first and second minimum levels, respectively, at the same time.

摘要： A controlled or zero backlash gearmotor comprises a main gearmotor, a secondary service gearmotor, an electronic control unit and transmission and synchronization gears. The backslash control results from the cooperation between the main gearmotor, the secondary service gearmotor, and the electronic control unit which adjusts, based on parameters detected by a series of sensors, the load provided by the service gearmotor on one of two irreversible screws pressing on two worm screws, respectively, arranged at the side of a worm wheel. This latter supports a secondary shaft and is get into gear with both the worm screws, the two worm screws being synchronized by means of gears connecting them to each other so that a reversible motion transmission is executable.

摘要： In accordance with an example embodiment, a wrist includes a frame, ring gear rotatable about a ring axis, and motor assembly with a pinion subassembly and motor with an output shaft. The pinion subassembly includes an internal spline and pinion connected to opposite sides of an internal shaft and rotatable about a pinion axis, and motor and frame bolt patterns. The motor is fastenable to the pinion subassembly at a plurality of motor-pinion indices via the motor bolt pattern. The pinion subassembly is fastenable to the frame mount at a plurality of pinion-frame indices via the frame bolt pattern so as to mesh the pinion with the ring gear and allow the output shaft to drive the ring gear via the internal spline, internal shaft, and pinion. The distance between the ring axis and the pinion axis varies for the plurality of pinion-frame indices.

摘要： A power transmission device capable of adjusting a torque to be applied to an output shaft easily and removing a backlash between gears exactly, and a display device and a display panel pedestal that have the power transmission device. A power transmission device 101 includes a display panel 102, an output shaft 103 to which the display panel is connected, output gears 104 and 105 rotating integrally with the output shaft, transmission gears 106 and 107 engaged with the respective output gears, motors 108 and 109 providing driving forces to the respective transmission gears, and a control circuit 110 controlling the motors. The control circuit 110 causes the motors 108 and 109 to rotate the transmission gears 106 and 107 at different rotation numbers, and to transmit different driving forces to the respective output gears 104 and 105. The output shaft 103 receives not only a torque on a rotation direction side, but also a torque on a side opposite to the rotation direction, whereby the occurrence of play due to the direction change of a weight torque of the display panel 102 is suppressed.

摘要： A positioning device without backlash includes a table and at least one gear operatively associated with the table. At least one worm gear is connected to the gear and the gear is driven in a desired direction with a primary motor and a synchronized slave motor.

摘要： A system used in a remotely controlled firearm device includes a circular gear and two worm gears. The worm gears engage the outer diameter of the circular gear and rotate synchronously to rotate the circular gear to align the firearm device with a target. Once the firearm device is aligned, the circular gear is locked into a fixed position that does not have any hysteresis by rotating the two worm gears asynchronously.
