When washings is dewatered, the at this moment solenoid energising in the clutch apparatus, the magnetic conduction iron hoop 912 of solenoid and clutch gear ring arranged outside interacts and can form the magnetic circuit of a closure, this moment, the magnetic conduction iron hoop drove the clutch gear ring along annular gear outer-wall down sliding (in such as Fig. 1 downward direction) under the effect of electromagnetic repulsive force, and the clutch gear ring will be arranged on the spring-compressed in the ring gear in sliding process, and the latch engagement connection that makes a plurality of teeth groove of being arranged on clutch gear ring lower end connecting portion and bogie one end together, thereby so that clutch gear ring and bogie connect as one, and then dehydration axle sleeve and bogie are connected as one, and make the dehydration axle sleeve obtain the rotating speed identical with bogie.Because the rotary inertia of the interior bucket that is connected with the dehydration axle sleeve is greater than the rotary inertia of the impeller that is connected with wash shaft, so spur gear and ring gear in the deceleration output block that is connected by wash shaft and impeller are in locking state, so that the deceleration output block is in locking state under the rotary inertia greatly at interior bucket, therefore whole deceleration input block and deceleration output block are along with bogie runs up together, and then drive the wash shaft be connected with it and also carry out High Rotation Speed in company with bogie, thereby the impeller high speed rotating that interior barrel of drive being connected with the axle sleeve that dewaters is connected with wash shaft is dewatered to washings.
When washings is washed, solenoid outage this moment, the closed magnetic circuit that forms between solenoid and the magnetic conduction iron hoop disappears, the clutch gear ring no longer is subject to the effect of electromagnetic force, therefore under the effect of spring restoring force, the clutch gear ring moves up along annular gear outer-wall, thereby the latch of a plurality of teeth groove of being arranged on clutch gear ring lower end connecting portion and bogie one end is broken away from, and then makes deceleration input block and deceleration output block enter duty:
As shown in figure 13, when bogie (is the wash shaft axis 50 shown in Figure 13 along counter clockwise direction shown in Figure 13 around the bogie axis, for convenience, below all this axis is referred to as the wash shaft axis) during High Rotation Speed, drive and carry out High Rotation Speed with the speed identical with it around the wash shaft axis with its eccentric bushing that is connected 4 in the counterclockwise direction with it, and the High Rotation Speed of eccentric bushing drives spur gear carries out off-centre around the wash shaft axis high speed revolution, when spur gear in high speed revolution process, its external tooth is meshed with the internal tooth of ring gear and produces mutual active force, thereby so that spur gear carries out rotation around spur gear axis 40, and the opposite direction of the direction of spur gear rotation and eccentric bushing rotation, as shown in figure 13, this moment, the direction of rotation of spur gear was clockwise, and its rotating speed is lower than the rotating speed of bogie.
Mesh and produce in the process of rotation at spur gear and ring gear, ring gear is rotated under its effect, because the internal tooth of ring gear and the outer between cog of spur gear exist tooth poor, therefore ring gear carries out low speed rotation, counter clockwise direction as shown in Figure 13 along the direction opposite with the spur gear direction of rotation.And be accompanied by the spur gear rotation, disk jockey in the output block in addition slows down, its rotation along with spur gear is rotated accordingly, and drive wash shaft carry out synchronized with spur gear, with the rotation of direction of rotation, and, make spur gear around the off-centre output that the rotation of wash shaft eccentric axis produces, be converted into along the output of wash shaft axis direction.
Concrete, spur gear is in the process of eccentric rotary, be packed in six connecting shaft holes of spur gear six connect bearing pins also with its synchronous rotary, because six other ends that connect bearing pins are against on the inwall of six through holes of terminal pad body and move in a circle on the wall within it, therefore six connect bearing pin jointly promote the terminal pad body and make the terminal pad body along with the rotation of spur gear synchronous rotary, and owing to cylinder and the wash shaft of terminal pad body upper end is connected, therefore when the terminal pad body rotates, can drive thereupon synchronous rotary of wash shaft, thereby the output that departs from the wash shaft axis direction that has produced when having realized the spur gear eccentric rotary is converted into and the output in the same way of wash shaft axis.
As shown in Figure 13, in the washing operating mode, when the bogie High Rotation Speed, deceleration input block and deceleration output block by the present embodiment, can make the dehydration sleeve that is connected with ring gear and the impeller that is connected with wash shaft obtain the rightabout low-speed motion that is lower than the bogie rotating speed, need the difficult problem that sleeve is fixed and need to consume mass energy of dewatering when washing thereby solved in the prior art.
The present embodiment is by being placed in internal rotor inside with deceleration input block and deceleration output block and clutch apparatus, thereby effectively utilized the inner space of internal rotor, reduced the volume of washing machine, be beneficial to the miniaturization production of washing machine, and, in the present embodiment, adopt the disk jockey that spur gear is connected with wash shaft, thereby the off-centre around the wash shaft axis of spur gear is exported the output that is converted into the wash shaft axis coaxle, avoid mechanical reduction gear to produce in the course of the work unnecessary vibration.
Except the mechanical reduction gear described in above-described embodiment, the utility model also provides a kind of washing machine, and it comprises the mechanical reduction gear described in the embodiment, adopt the washing machine of above-described embodiment middle gear deceleration device, its compact conformation, volume is little, is convenient to the miniaturization production of product.
In washing machine of the present utility model, for axial float or the displacement that prevents wash shaft, can install a plurality of jump rings and other identical functions parts additional in the suitable position of wash shaft or dehydration axle sleeve; For the ease of installing and load-bearing, can install in the suitable position of wash shaft pad and other identical functions parts additional; For normal delivery and the installation of satisfying drive connection of the present invention, can a plurality of oiliness bearings and a plurality of ball bearing be set at different parts, as between wash shaft and dehydration axle sleeve, a plurality of oiliness bearings being set, between ring gear and dehydration axle sleeve, between mounting disc and the dehydration axle sleeve and between electric motor end cap and the wash shaft a plurality of ball bearings are set, more specifically, described ball bearing can be deep groove ball bearing.Preferably, between the ball bearing between electric motor end cap and the wash shaft and wash shaft, can be provided for playing the lining of oiliness bearing function.In order to prevent that washings from entering in deceleration input block and deceleration output block and the motor along wash shaft, dehydrating shaft cover and mounting disc, between wash shaft and dehydration axle sleeve, little water seal is set, between dehydration axle sleeve and mounting disc, large water seal is set.Preferably, in order to realize the damping noise abatement when working, between each build-up member, install the beam that plastic material or elastomeric material are prepared from additional, and under the condition that satisfies installation strength or correlation function, housing unit is adopted casting aluminium material, or adopt plastics to be prepared from ring gear.
