Abstract: A driving device and a seat adjusting mechanism for vehicle are provided. The driving device includes a motor and a gearbox. The gearbox includes a worm and a worm gear. The worm is fixedly connected to an output shaft of the motor. The gearbox further includes first and second driving gears, and first and second driven gears. The first and second driving gears are coaxially fixed to the worm gear and located at two sides of the worm gear, respectively. The first and second driven gears are fixed coaxially with each other and engaged with the first and second driving gears, respectively. Two driving gears are arranged at the two sides of the worm gear symmetrically, and two driven gears are also arranged at the two sides of the worm gear symmetrically, which results in a compact structure and reduced volume of the driving device.

Abstract: An actuator and its clutch are provided. The clutch includes a driving shaft; a mounting base fixed to the driving shaft for rotation with the driving shaft; a connecting base for connecting with a load, the connecting base including fingers surrounding an outer circumference of the driving shaft; resilient member including a resilient member, the resilient member having two ends respectively fixed to the mounting base and the connecting base, the resilient member surrounding an outer circumference of the connecting tabs. When a rotation speed of the driving shaft is greater than a rotation speed of the connecting base, an inner diameter of the resilient member gradually decreases so as to gradually couple the coupling portion with the driving shaft, such that the rotation speed of the coupling portion gradually approaches or reaches the rotation speed of the driving shaft. The present invention can provide a buffering function at the phase of the startup of the motor to avoid the motor startup failure and damage to the motor.

Abstract: The present invention relates to a ring gear and a gear reduction device. The ring gear includes an annular body with a plurality of mounting portions, and a plurality of teeth arranged on an inner circumferential surface of the annular body. The annular body and the teeth are integrally formed from powder metal, and the mounting portions and the teeth are at least partly overlapped in an axial direction of the annular body. The mounting portions are integrally formed with the annular body and the teeth, which results in concentricity between the mounting portion and the teeth being improved and cost of the ring gear being reduced. Furthermore, the mounting portions are overlapped with the teeth, which reduces the axial size of the ring gear.

Abstract: A mounting structure and a gear motor are disclosed. The mounting structure includes at least one first hole formed in a first component of the gear motor, at least one second hole formed in a second component of the gear motor, arranged coaxially with the first hole, and at least one expansion member extending into the first and second holes. The expansion member has an interference fit with one of the first and second holes, and has a transition fit with the other of the first and second holes. The present invention can effectively prevent falling off of the expansion member, and reduce the assembly difficulties of the gear motor as well as the degree of deformation of the expansion member during the assembly process.

Abstract: A driving apparatus for a washing machine includes a single-phase outer rotor brushless motor and a driving wheel. The motor drives the driving wheel and includes a stator and a rotor. The stator includes a stator core and windings wound around the stator core. The rotor includes a rotor yoke, and a permanent magnet. An inner surface of the permanent magnet and an outer surface of a tooth tip are opposed to each other and define an uneven gap there between for allowing the rotor to rotate relative to the stator. A radial width of the gap associated with each magnetic pole progressively increases from a center portion toward circumferential ends of the magnetic pole, and a radial width of the gap associated with each magnetic pole is symmetrical with respect to a center axis of the magnetic pole along the circumferential direction.
