摘要： In an example, the present invention provides a solar tracker apparatus configured with an off-set drive assembly. In an example, the apparatus has an inner race structure, which has a cylindrical region coupled to a main body region, the main body comprising an off-set open region. The cylindrical region is an annular sleeve structure coupled to the main body region, which occupies the spatial region within the cylindrical region. In an example, the apparatus has an outer race structure coupled to enclose the inner race structure, configured to couple the inner race structure to allow the inner race structure to move in a rotational manner about a spatial arc region; and configured to allow the inner race structure to pivot about a region normal to a direction of the spatial arc region. In an example, the solar tracker has a clamp assembly that is configured to pivot a torque tube.

摘要： A spring winding device, a counterbalancing force adjustment device for a counterbalancing mechanism, and a method of adjusting an amount of force stored in a spring of a counterbalancing mechanism are provided. The spring winding device includes a support bracket, a worm gear, and a drive gear. The worm gear is rotatably coupled to the support bracket and includes a mount portion for coupling a first end cone thereto. The drive gear is rotatably disposed adjacent the support bracket and is drivingly engaged with the worm gear. A rotation of the drive gear causes the worm gear to rotate within the support bracket. The spring winding device does not require pretensioning using winding rods, maintains rigidity and alignment when a counterbalancing force is applied, and decreases a cost and a complexity of the counterbalancing mechanism.

摘要： In a speed reducer of an electric power steering system, a first bearing supports a first end portion of a worm so that the first end portion is movable in an axial direction. Elastic members elastically support the worm in the axial direction. A second bearing supports a second end portion of the worm. An urging member oscillates and urges the worm. The sum of first frictional resistance in the axial direction between an inner ring of the first bearing and the worm and second frictional resistance in the axial direction between the urging member and an outer circumference of an outer ring of the second bearing is less than engagement frictional resistance in the axial direction of the worm.

摘要： A coupling member has a first driven portion and an output shaft to be coupled to a lamp unit, and is rotatable in the horizontal direction about the shaft center of the output shaft. A driven member has a second driven portion and a follower portion, and is rotatable relative to the coupling member. An acting portion is engaged with the follower portion. A first driving unit is engaged with the first driven portion to rotate the coupling member relative to the driven member. A second driving unit is engaged with the second driven portion to rotate the driven member relative to the coupling member. When the second driving unit rotates the driven member, the acting portion engaged with the follower portion causes the rotation center to move, and the coupling member is moved together with the driven member.

摘要： A power actuator is provided for a door latch. A transfer lever within the housing is selectively coupled to a motor-driven worm gear via a lost motion connector. Engaging the motor moves the transfer lever between a locked and an unlocked position, actuating an output lever mounted to a spline on the transfer lever. The worm gear returns to a neutral position when the motor is disengaged, leaving the transfer lever in either the locked or unlocked positions. Manually moving the output lever causes the transfer lever to move between its locked and unlocked positions without back-driving the worm gear. A toggle mechanism prevents the transfer lever from accidentally moving or only moving partially between the locked and unlocked positions.

摘要： Reduction gear units are provided comprising a gearbox, a cam assembly, a bearing assembly, a first gear and a second gear. The first and second gears may engage one another and translate rotating movement from one axis to an axis perpendicular thereto. The second gear is disengagable from the first gear by action of the cam assembly, which is adapted to disengage the second gear from the first gear through eccentric rotation of the cam assembly. In one embodiment, a bearing assembly carried by the cam assembly is preloaded. The cam assembly is disposed so that the preloaded can be maintained during manufacture of the gearbox. In another embodiment, the gearbox case and cam assembly are disposed so as to minimize internal leakage from the case and enhance sealing of the gearbox.

摘要： A high-load linear actuator includes a driving mechanism, a worm shaft, a worm wheel assembly, a lead screw, a telescopic pipe and an outer pipe. The driving mechanism includes a base and a motor. The base has a supporting portion and an accommodating portion. The motor is fixed to the supporting portion. The worm shaft extends from the motor into the supporting portion. The worm wheel assembly includes a worm wheel and two bearings for supporting the worm wheel in the accommodating portion. The worm wheel is engaged with the worm shaft. The lead screw is disposed through the worm wheel and driven by the motor for rotation. The telescopic pipe slips on the lead screw to be threadedly connected therewith. The outer pipe slips on the telescopic pipe. The rotation of the lead screw drives the telescopic pipe to linearly extend or retract relative to the outer pipe.

摘要： A xyθ precision alignment platform is provided. The alignment platform includes three power units and three moving platform. Two of the power units can drive a third moving platform moving in X or Y direction. The other power unit has a worm which can drive an arcuate teeth arrangement disposed between the second moving platform and the third moving platform to drive the third moving platform rotating. Whereby, since the worm is arranged to drive the arcuate teeth arrangement laterally, the alignment platform is thin and the rotative movement of the third moving platform can be precisely controlled. Additionally, each power unit may be electrically connected to a controller for respectively driving and controlling each power unit. When only the rotation of the third moving platform is required, only one of the power units needs to be driven, thus simplifying the operation of the alignment platform and improving the work efficiency.
