The present invention relates to be used for the reduction gear component of use in shaft assembly of washing machine, relate in particular to the big reduction gear component of speed reducing ratio between power shaft and the output shaft.
Common automatic washing machine as shown in Figure 1 comprises that a dehydration barrel 5, that is installed in the wash bucket 4 by a plurality of wash buckets 4, that are installed in suspender 15 supportings on the shell 1 is installed in the impeller 6 of dehydration barrel 5 bottoms, the shaft assembly 8 that a motor 7 and that drives impeller 6 is used for the driving force of motor 7 is delivered to impeller 6 and dehydration barrel 5.
When washing machine brought into operation, slurry infeeded in wash bucket 4 and the dehydration barrel 5 by water supply installation 3, when the operation of supplying water is finished, and motor 7 entrys into service.The torque of motor 7 passes to shaft assembly 8 by belt 7a, and shaft assembly 8 rotates impeller 6 then.The rotation of impeller 6 makes in the dehydration barrel 5 and eddy current occurs, washs the clothing that is contained in the dehydration barrel 5 by this eddy current.
When washing operation was finished, the washings in the dehydration barrel 5 were discharged by the water discharge outlet 5a and the drainage arrangement 9 that form in dehydration barrel 5 sides.When drain operation was finished, dehydrating operations began.
Have in the dehydration, motor 7 runs up, and shaft assembly 8 is delivered to impeller 6 and dehydration barrel 5 simultaneously with the torque of motor 7.After this, dehydration barrel 5 and impeller 6 be high speed rotating together, makes clothes dewatering by action of centrifugal force.
Fig. 2 is the Zoom Side cutaway view of shaft assembly 8, and Fig. 3 is the partial enlarged drawing of Fig. 2.Shaft assembly 8 comprises power shaft 24 and the output shaft 29 that inserts lower casing 21 and upper casing 20 respectively, be installed in the reduction gear component 10 between power shaft 24 and the output shaft 29, be installed in the outer and coaxial quill shaft 23 of power shaft 24 with power shaft 24, be installed in outer and coaxial with output shaft 29 dehydrating shaft 30 of output shaft 29, supporting quill shaft 23 and dehydrating shaft 30 are so that the bearing 22a of its rotation and 22b and being used to selects to wash the clutch rod 32 with dehydrating operations.
Rotating shaft belt pulley 24a is installed on the power shaft 24, and this rotating shaft belt pulley 24a is connected with motor 7 by belt 7a.Power shaft 24 and quill shaft 23 are connected to each other by clutch spring 26.The clutch operation of clutch spring 26 is controlled by clutch sleeve 25, and clutch sleeve 25 is then handled by clutch rod 32.
Reduction gear component 10 comprise a brake drum 28, one be installed in internal gear 27 on the brake drum 28, one and internal gear 27 coaxial installations and by pressure insert and the central gear 24b that is assembled together with power shaft 24, a plurality of that install around central gear 24b and with internal gear 27 and central gear 24b planet gear meshed 28a.Each planetary gear 28a the axle 28b by a upper supporting part 33 and a lower supporting part 34 rotating supports, upper supporting part 33 is connected with output shaft 29, and with output shaft 29 co-rotation.Output shaft 29 is connecting impeller 6.
Under the situation that brake drum 28 is fixed by external force, when power shaft 24 rotated, central gear 24b rotated planetary gear 28a.The rotation of planetary gear 28a makes output shaft 29 rotate again.In this case, because the velocity of rotation of planetary gear 28a is lower than central gear 24b, the velocity of rotation of output shaft 29 is lower than power shaft 24, so the rotation of power shaft 24 is to pass to output shaft 29 with ways of deceleration.Therefore, when motor 7 rotated, impeller 6 was to slowly run.
In rotational direction fixed to one another together the time by clutch spring 26 at power shaft 24 and quill shaft 23, if rotating shaft belt pulley 24a rotates, rotating shaft belt pulley 24a rotates brake drum 28, and brake drum 28 rotates dehydration rotating shaft 30.Therefore, dehydration barrel 5 high speeds are rotated, and make the clothes dewatering in the dehydration barrel 5.
Clutch rod 32 is driven by the drain motor (not shown).Clutch rod 32 is controlled brake band 31 and the clutch sleeve 25 that is positioned at brake drum 28 1 sides simultaneously.
During washing operation, clutch rod 32 drives brake band 31 to brake brake drum 28 and to drive clutch sleeve 25 to discharge clutch spring 26.Therefore, the torque of rotating shaft belt pulley 24a is delivered on the impeller 6 by power shaft 24, reduction gear component 10 and output shaft 29, and makes impeller 6 low speed rotation.
During dehydrating operations, clutch rod 32 drives brake band 31 with release brake drum 28, and 25 pairs of clutch springs of driving clutch sleeve 26 carry out the clutch operation.After this, rotating shaft belt pulley 24a makes power shaft 24 rotate with quill shaft 23, and brake drum 28 and dehydrating shaft 30 rotate with quill shaft 23 then.Therefore, the dehydration barrel 5 that is connected on the dehydrating shaft 30 is rotated at a high speed.
Usually, during dewatering operation of washing machine, the rotating speed of dehydration barrel is high more, and dehydrating effect is good more, but during washing operation, impeller 6 should rotate with suitable speed (for example 120 to 150 rev/mins), so that do not damage clothing.Yet, if rotate with the high speed (approximately greater than 900 rev/mins) that is suitable for dehydrating operations in order to make dehydration barrel 5, and the rotating speed of raising motor 7, the rotating speed of impeller 6 also can improve thereupon during washing operation so, and the therefore undue rotating speed that improves motor 7 is not the best way.Therefore, if during the washing operation during the rotating speed of impeller 6 and the dehydrating operations speed discrepancy of dehydration barrel 5 very senior general be very desirable.
The rotating ratio of impeller 6 and dehydration barrel 5 is determined by gear assembly 10.Yet, in order to improve rotating ratio, just should increase the size of planetary gear 28 with gear assembly 10, this will make the overall dimensions of shaft assembly 8 increase.The problem of thereupon bringing is that the size of shaft assembly 8 may reach production cost too greatly and may improve.
The present invention is intended to solve the aforementioned problems in the prior, and therefore, the purpose of this invention is to provide a kind of reduction gear component that is used for use in shaft assembly of washing machine, and this assembly makes the very big speed reducing ratio of existence between power shaft and the output shaft.
