Description
Technical field
The utility model relates to a kind of washing machine, specifically refers to a kind of clutch coupling of washing machine.
Background technology
At present, occurred on the domestic and international market the 4th generation washing machine, i.e. impeller-type " double dynamical " or " three power " washing machine.The former generally includes bucket in a washing wave wheel that is connected with this clutch impeller axle, the washing that is connected with the wash-out axle.When the washing operating mode, washing wave wheel and the opposite direction running by a certain percentage of the interior bucket of washing.And the latter's big wave wheel is connected with the wash-out axle, stirs impeller and is connected with wash shaft, and bucket is connected with dehydrating shaft in the washing.When the washing operating mode, bucket anti-running mutually by a certain percentage in big wave wheel, stirring impeller and the washing.Because above-mentioned washing machine all can produce strong washing current, clothing is carried out three-dimensional washing by rubbing with the hands, greatly improve wash ratio, also avoided clothes washing wrapping phenomena, therefore " double dynamical " or the equal broad market prospect of " three power " washing machine simultaneously.
Because the bucket rotary inertia is big in the washing of above-mentioned washing machine, thereby the drive mechanism of clutch there is very high requirement.Main element---clutch as existing " double dynamical " or " three power " washing machine, though can satisfy the functional requirement of washing machine basically, but weak point is arranged all structurally, the decelerating clutch of washing machine system strength is on the low side, carrying capacity is relatively poor as homemade " double dynamical " or " three power ", so service life is not ideal, is confined to the low capacity washing machine and uses; And " double dynamical " clutch component of external import exists accuracy of manufacture height, the assembling difficulty, and running noise is big, and single cost height produces defectives such as difficulty in batches.
Existing domestic clutch coupling of washing machine generally includes a power shaft that is connected with belt pulley, and this belt pulley is connected with a driving motor as power source; The other end of this power shaft is provided with input shaft gear; This input shaft gear drives upper planet wheel counter-rotating, and this upper planet wheel drives planet carrier, output shaft and impeller forward rotation; Meanwhile, this planet carrier drives a sun gear forward rotation again, and this sun gear drives lower planetary gear counter-rotating, and this lower planetary gear drives ring gear, output sleeve and interior bucket counter-rotating.
After adopting above-mentioned clutch coupling of washing machine, though can produce strong washing current and tool excellent cleaning effect.Yet what its weak point was to be meshed with upper planet wheel, lower planetary gear is same ring gear, and promptly this ring gear is set to ring gear and following ring gear, and is meshed with upper planet wheel, lower planetary gear respectively.Such structural design is unfavorable for the processing technology of this ring gear and the control of machining accuracy; Secondly, last ring gear is necessary for the same number of teeth with following ring gear, is unfavorable for redistributing this output shaft, output sleeve gearratio with respect to power shaft, i.e. speed ratio adjusting is difficult relatively.
Summary of the invention
Technical problem to be solved in the utility model is exactly the present situation at above-mentioned prior art, provide a kind of ratio wheel architecture simple, can adjust speed reducing ratio arbitrarily, thereby can be applied to the clutch coupling of washing machine of various washing machine capacities.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this clutch coupling of washing machine comprise an end install cogged power shaft, clutch shaft, wash-out axle, impeller axle and with the joining ring gear of wash-out axle, wherein said power shaft is sleeved in the clutch shaft, clutch shaft is connected mutually with the brake disc of strap brake band again, and described impeller axle is arranged in the described wash-out axle, described ring gear is meshed with planetary gear with second planet axis, it is characterized in that:
A, described gear are meshed with a planetary gear in the double-planetary gear that has first planet axis, and another connection planetary gear of this double-planetary gear is engaged in the sun gear in the duplex sun gear, another connection sun gear in the described duplex sun gear then is meshed with the above line star-wheel, and this duplex sun gear also is connected with described impeller axle;
The two ends of b, above-mentioned first planet axis are nested with respectively on described clutch shaft and lower planet frame, described lower planet frame then with described clutch shaft Joint, and described second planet axis, one end is set on the described lower planet frame, and the other end then is enclosed within on the upper planet frame that is positioned at this lower planet frame top.
As further improvement of the utility model, be nested with a dehydrating shaft outside the described wash-out axle, described dehydrating shaft and described brake disc are fixedly connected.After adopting such structure, can be made into many axles and export formed many power decelerators, thus the scope of application of expansion the utility model clutch coupling of washing machine.
Described ring gear can be connected with described wash-out axle by adapter sleeve.
Described double-planetary gear can be made as 2 to 4; The best is made as 4, is beneficial to the uniform of train driving force and stable drive, reduction work noise.
In like manner, described planetary gear is also to be distributed with 2 to 4 for good.
Compared with prior art, because the utility model has adopted the kind of drive of double-planetary gear and duplex sun gear, ring gear only is meshed with planetary gear, so double-planetary gear, the duplex sun gear, the number of teeth in the planetary gear can conveniently be adjusted, can adjust the speed reducing ratio of clutch arbitrarily, thereby it is simple in structure that the utility model had both been had, intensity is good, and bearing capacity is strong, long service life, noise is little, the inner body accuracy of manufacture requires low, easy to assembly, the characteristics of low cost of manufacture, simultaneously can satisfy the supporting widely demand of different type of machines again, and have more the market competitiveness.
