A strain wave gear apparatus includes a rigid internal gear, a flexible external gear, and a wave generator. The wave generator includes an input shaft fixing member including eccentric cams, bearings respectively fixed to outer sides of the eccentric cams, and housings respectively fitted to outer peripheral surfaces of the bearings. The eccentric cams are arranged side by side in a direction of an inclined axis inclined with respect to an input rotation axis at an inclination angle (θ) in a manner that respective center axes of the eccentric cams are parallel to the inclined axis and decentered in directions opposite to each other from the inclined axis. The housings are each formed into a tapered shape so that an outer peripheral surface of each of the housings is held in surface contact with an inner peripheral surface of the flexible external gear.

The invention discloses a decelerating clutch of an intelligent washing machine. The decelerating clutch comprises an upper shell, a lower shell, a connection plate, a torque transmission shaft sleeve and a brake wheel axle. The connection plate is arranged on the brake wheel axle in a sleeving mode. The connection plate is provided with a magnet, a Hall sensor is arranged on the lower end face of the lower shell, the position of the Hall sensor is matched with the position of the magnet, and a gap is reserved between the Hall sensor and the magnet. First splines are arranged on the outer surface of the brake wheel axle, second splines matched with the first splines are arranged on the inner surface of an inner hole of the connection plate, third splines are arranged on the lower end portion of the connection plate, and fourth splines matched with the third splines are arranged on the upper end portion of the torque transmission shaft sleeve. A connection plate spring and a spring gland are arranged at the upper end of the connection plate. The spring gland is located at the upper end of the connection plate spring, and the spring gland abuts against the lower shell. According to the technical scheme, the decelerating clutch of the intelligent washing machine is reasonable in structural design, simple in structure, convenient to assemble, reliable in clutch action, stable in torque transmission and high in safety.

The invention relates to a clutch combined with self-adaption control method based on a statistics principle. The clutch combined with self-adaption control method comprises the steps that at each clutch combination stage, the difference between the rotation velocity of an engine and the rotation velocity of the input shaft of a gearbox is divided to be five rotation velocity difference ranges; the time from a clutch be in contact firstly to the rotation velocity of the input shaft of the gearbox being synchronous with the rotation velocity of the engine is recorded; the percentage of the timeof the difference between the rotation velocity of the engine and the rotation velocity of the input shaft of the gearbox in each rotation velocity difference range accounting for the time from the clutch being in contact firstly to the rotation velocity of the input shaft of the gearbox being synchronous with the rotation velocity of the engine is counted; and the compensation factor of clutch combined control in the next clutch combination stage is obtained. The compensation factor of the next clutch combined control is obtained through the difference between the rotation velocity of the engine and the rotation velocity of the gearbox in each clutch combination stage, the change of clutch transmission torque feature is automatically adapted, stable and smooth clutch transmission torqueis ensured, so that the torque of the engine is matched with the clutch transmission torque, and the riding comfort of vehicle starting and gear shifting is guaranteed.
