Description
Technical field
The present invention relates to a kind of motor and speed-reducing clutch assembly, especially be fit to be applied to the washing machine field.
Background technology
As everyone knows, in the washing machine field, be installed in the motor of washing machine internal and speed-reducing clutch and be connected and realize driving function to washing machine as the driving mechanism of washing machine.How to satisfy under the prerequisite of performance, constantly reducing the installation volume of driving mechanism for washing machine or space hold and manufacturing cost thereof and become the two large technical problems that washing machine manufacturer in recent years endeavours to pursue.
In order to solve the problems of the technologies described above, domestic have more Patents technology open, but mostly still rest on the optimization localized design, and these contributions for this area remain very little.The applicant and other applicant of being associated are in order to solve these technical problems, since 2010, tens patent applications have been proposed, made largely contribution for solving above two large technical problems, comparatively typically have: be that the Chinese invention patent of CN102345219A discloses a kind of speed reducing shaft clutch for washing machine such as patent publication No., have driving shaft and propeller shaft sleeve, driving shaft has driving shaft and the power transmission shaft of the coaxial setting of above-below direction, driving shaft is connected with drive motors, its arranged outside planetary wheeling assembly, planetary wheeling assembly has the planetary gear retainer, be arranged on the planetary gear retainer, and the planetary gear that is meshed with driving shaft and the planetary gear external toothing that is arranged on the planetary gear outer ring and is meshed with planetary gear, the planetary gear external toothing is connected with power transmission shaft, planetary gear external toothing outside socket profile of tooth clutch ring, spline fitted and above-below direction are slidingly connected between profile of tooth clutch ring and the planetary gear external toothing, profile of tooth clutch ring lower end is provided with gear shaping, profile of tooth clutch ring below is provided with the slot dish that is fixedly connected with driving shaft, the slot dish is provided with the slot that matches with profile of tooth clutch ring lower end gear shaping, and profile of tooth clutch ring top is provided with solenoid.Yet its motor still need arrange two independently driving shaft and power transmission shafts, and subsequent production more needs related fittings and installation procedure thus, when increasing the cost load, has increased especially taking of installation volume.
And for example patent publication No. is that the Chinese invention patent application of CN102677427A discloses a kind of washing machine driver, comprise motor, wash shaft, be sleeved on dehydration axle sleeve and gear reduction on the described wash shaft, it is inner and affixed with the output gear of described gear reduction that described wash shaft is coaxially installed on the rotor of described motor, and the input gear axle of described gear reduction is plugged in the axis hole of described rotor.Because the input gear axle of gear reduction is inserted in the axis hole of rotor, make rotor as the tooth rest of gear reduction, effectively gear reduction and motor are become one, thereby reduced the axial dimension of washing machine driver, so that this washing machine driver is simple and compact for structure, take up room little.Although this structure has reduced axial dimension, or because its operation principle is directly as the input gear axle with rotor, be only suitable for using and the gear with small teeth difference mechanism that does not have sun gear, range of application is restricted, and the defectives such as the transmission efficiency that few poor gear mechanism itself exists is low, so the proposition of this patent still can not be satisfied the widespread demand in the reality.
Under this technical background, along with the applicant gropes to seek a kind of both taking up room and manufacturing cost of effectively low driving mechanism for washing machine in the constantly research of this area, and motor applied widely and speed-reducing clutch assembly are used as the driving mechanism of washing machine.
