Below with reference to Fig. 1-Fig. 4, the clutch pack 100 for washing machine according to the utility model embodiment is described.The clutch pack 100 for washing machine according to the utility model embodiment can comprise power transmission shaft 10, planetary gears 20, wash shaft 30, dehydrating shaft 40, clutch cover 50, clutch shaft 60 and switching device shifter 70.
As shown in Figure 1, the outer peripheral face of power transmission shaft 10 is provided with the power transmission shaft gear teeth 11, planetary gears 20 comprises planetary gear 21, planet carrier 22 and gear ring 23, and planetary gear 21 engages to rotate with power transmission shaft 10 with the power transmission shaft gear teeth 11, and gear ring 23 and planetary gear 21 engage.Wash shaft 30 and planet carrier 22 are fixed, and dehydrating shaft 40 is set in wash shaft 30, and dehydrating shaft 40 is fixed with gear ring 23.That is, power transmission shaft 10 can as the power intake of planetary gears 20, and when the clutch end of planet carrier 22 as planetary gears 20, planet carrier 22 can drive wash shaft 30 to rotate to make washing machine enter washing state; When the clutch end of gear ring 23 as planetary gears 20, gear ring 23 can drive dehydrating shaft 40 to rotate to make washing machine enter dewatering state.
Clutch cover 50 is fixedly connected on power transmission shaft 10, and clutch cover 50 is provided with the first spline (scheming not shown), clutch shaft 60 is set on power transmission shaft 10, and clutch shaft 60 is spaced apart along the axial direction (above-below direction namely shown in Fig. 1) of power transmission shaft 10 with clutch cover 50, clutch shaft 60 and gear ring 23 are fixed.Switching device shifter 70 is set on clutch shaft 60 slidably, and switching device shifter 70 comprises ball bearing 80 and the contiguous clutch cover 50 of the second spline 71, second spline 71 is arranged.Wherein, when washing of drum type washing machine, ball bearing 80 braking clutch axle 60, and also the first spline is separated with the second spline 71; When laundry machine dehydration, ball bearing 80 discharges clutch shaft 60, and the first spline engages with the second spline 71 to make clutch shaft 60 drive dehydrating shaft 40 to rotate.
As shown in Figure 1, when the first spline is separated with the second spline 71, the power of power transmission shaft 10 cannot be directly passed to clutch shaft 60 by clutch cover 50.The Power output of power transmission shaft 10 is to the planetary gear 21 of planetary gears 20, and because clutch shaft 60 and gear ring 23 are fixed, that is, ball bearing 80 is braking clutch axle 60 and gear ring 23 simultaneously.Thus, planet carrier 22 drives wash shaft 30 to rotate as the clutch end of planetary gears 20, thus washing machine enters washing state.
When laundry machine dehydration, the first spline and the second spline 71 engage, and the power of power transmission shaft 10 can pass to planetary gear 21 on the one hand, and planet carrier 22 drives wash shaft 30 to rotate; The power of power transmission shaft 10 can pass to clutch shaft 60 by clutch cover 50 on the other hand, and clutch shaft 60 passes to gear ring 23, and gear ring 23 drives dehydrating shaft 40 to rotate, thus washing machine enters dewatering state.Particularly, as shown in Figure 1, clutch pack can also comprise brake disc 24, and gear ring 23, clutch shaft 60 are fixedly connected with brake disc 24, and one end of brake disc 24 is fixedly connected on dehydrating shaft 40 to make clutch shaft 60 that dehydrating shaft 40 can be driven to rotate.It should be noted that, ball bearing 80 has the function of unidirectional locking clutch shaft 60, because washing machine is different with the rotation direction of the clutch shaft 60 during dehydration in washing, during setting washing of drum type washing machine, ball bearing 80 braking clutch axle 60, during laundry machine dehydration, ball bearing 80 discharges clutch shaft 60.
Thus, according to the clutch pack 100 for washing machine of the utility model embodiment, by arranging switching device shifter 70, the washing of washing machine and the switching of dehydration can be realized, and the good reliability of switching device shifter 70, thus the performance of washing machine can be promoted.In addition, by arranging switching device shifter 70, brake ribbon and the clutch bearing of washing machine of the prior art can be omitted, thus the noise produced when can eradicate brake ribbon brake, reduce the laundry noise of washing machine, and the manufacturing cost of washing machine can be reduced.
In examples more of the present utility model, as shown in Figure 2, switching device shifter 70 can also comprise housing 90, and housing 90 is connected with the second spline 71, and housing 90 has the holding tank (scheming not shown) holding ball bearing 80.Particularly, housing 90 can comprise: dividing plate 91, annular perisporium 92 and limiting plate 93, dividing plate 91 is arranged between ball bearing 80 and the second spline 71, annular perisporium 92 is connected with dividing plate 91, and annular perisporium 92 extends to the direction (namely shown in Fig. 2 from the top down) away from the second spline 71, ball bearing 80 is only against in annular perisporium 92, and limiting plate 93 is connected with annular perisporium 92, and limiting plate 93 is positioned opposite to form holding tank with dividing plate 91.By arranging holding tank, ball bearing 80 can be arranged on the opposite side of the second spline 71.Alternatively, the second spline 71, dividing plate 91 and annular perisporium 92 can be formed in one, thus can improve the structural strength of housing 90, extend the service life of switching device shifter 70 further, improve the performance of washing machine.
Alternatively, the first spline can be external splines, and the second spline 71 can be internal spline.But the utility model is not limited to this, in the unshowned embodiment of the utility model, the first spline can also be internal spline, and the second spline 71 can be external splines.
In concrete examples more of the present utility model, ball bearing 80 comprises: body 81, multiple ball 82 and multiple elastic component.The internal perisporium of body 81 is formed with multiple isolated limited impression (scheming not shown), ball 82 and limited impression one_to_one corresponding, when ball 82 rolls in limited impression, ball bearing 80 discharges clutch shaft 60, when ball 82 rolls out limited impression, ball bearing 80 braking clutch axle 60.Each elastic component is arranged between two adjacent balls 82.Alternatively, elastic component can be shell fragment.
