After the electromagnetic clutch device energising, produce magnetic field around the solenoid 42, because coil retainer 44 is a magnetic conductor; So produce electromagnetic force between the magnetic conductive part of coil retainer 44 and clutch fluted disc 41; The elastic force that clutch fluted disc 41 can overcome spring 45 passes through idler gear 331 axially to front slide, makes clutch fluted disc 41 and installing plate 11 engage, at this moment behind the electrical power; Can realize the output of output shaft 26 low speed through gear reduction, realize washing function; After the electromagnetic clutch device outage, magnetic field disappears, under the elastic force effect of spring 45; Clutch fluted disc 41 axially slides backward through idler gear 331, makes clutch fluted disc 41 and installing plate 11 throw off, and the while engages with rotor 23; The gear reduction self-locking; Behind the electrical power, output shaft 26 rotates with speed with rotor 23 at this moment, the realization dehydrating function.
Here need to prove; Arrangement of clutch also can be connected the conversion that realizes washing operating mode and dehydration condition with rotor engaging or disconnection through other driving members of driven gear reducing gear, as long as the setting of arrangement of clutch can realize the conversion of roller washing machine washing operating mode and dehydration condition.
In the course of the work, when rotor 23 rotates with output shaft 26, can produce friction inevitably; In order to reduce friction; Can rotor 23 and output shaft 26 between plane bearing 68 is set, to slow down the pivoting friction between rotor 23 and the output shaft 26, prolong working life.
Further, between output shaft 26 and coil retainer 44, jump ring is set and limits moving axially of output shaft 26.
In order to make in the course of work, output shaft 26 can more stably rotate, and between output shaft 26 and installing plate 11, is provided with first rolling bearing 651 and second rolling bearing 652.
Further, between the rotor 23 and second gear ring 332, neck bush 66 is set, on output shaft 26, jump ring is set, in order to moving axially of restriction rotor 23.
Further, between output shaft 26 and installing plate 11, water seal 51 is set, washings get into internal drive when preventing work.
The roller washing machine driver that the utility model provided adopts gear reduction as reducing gear; During the washing operating mode; Motor is run up, and the rotating speed of the deceleration regulation and control output shaft through gear reduction realizes importing at a high speed low speed output; Improved the service efficiency of motor, cut down the consumption of energy; During dehydration condition, the adjusting through arrangement of clutch makes gear reduction realize self-locking, makes output shaft and rotor same rotational speed simultaneously, the realization high speed dewatering.Because the deceleration excursion of gear reduction is big, can be implemented in that motor all is in the state of running up under washing and the dehydration condition, make the service efficiency of motor increase substantially.
In addition, the utility model becomes one the tooth rest of rotor as gear reduction effectively with motor and gear reduction, simplify the structure, and makes the simple and compact for structure of roller washing machine driver, and it is little to take up room.
More than the driver of the roller washing machine that the utility model provided has been carried out detailed introduction.Used concrete example among this paper the principle and the embodiment of the utility model are set forth, the explanation of above embodiment just is used to help to understand the method and the core concept thereof of the utility model.Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
