Above the bearing 32 of dehydrating shaft 24 bottoms, be provided with the roller-type one way clutch 43 of the device that prevents that rotary barrel 13 from reversing, this be elaborated below with reference to Fig. 1, Fig. 3 and Fig. 4.This one-way clutch 43 is to be made of the outer shroud 45 that is roughly housing 44 cylindraceous, is pressed into the spline state in the inside of this housing 44 and a plurality of rollers 46 of installing between the lower hollow axle 26 of the inner surface of this outer shroud 45 and aforementioned dehydrating shaft 24.As shown in Figure 3, in the bottom of above-mentioned housing 44 other ends, be provided with the telescoping part of projection, as flange 47, the external surface shape of this flange 47 constitutes the hex shape of non-circular shape (this example is the regular hexagon shape).
The bearing holder (housing, cover) 48 that the housing 44 of above-mentioned one-way clutch 43 and bearing 32 are used by spline is formed one.Specifically as shown in Figure 3, the bearing holder (housing, cover) 48 that this spline is used comprises cylindric part 48a, the end face 48b that is provided with to the inside in the upper end of this cylindric part 48a, be provided with up the cross section of projection on this end face 48b is the barrel 48c of regular hexagon and is provided with the end face 48e with through hole 48d to the inside in the upper end of this barrel 48c, has constituted the bearing holder (housing, cover) 48 that spline is used therefrom.Then, be pressed into bearing 32 peripheries and be the outer ring and be entrenched in spline with in the cylindric part 48a of bearing holder (housing, cover) 48 with the state of spline, simultaneously in barrel 48c with the flange 47 of the housing 44 of the chimeric one-way clutch 43 of the state of spline.This situation, spline have formed the embedded hole part of non-circular shape with the barrel 48c of bearing holder (housing, cover) 48.
The cylindric part 48a of the bearing holder (housing, cover) of using by spline 48 is pressed into above-mentioned bearing 32 in the chimeric recess that the bearing that is fixed on supporting lower house 20 uses, and this cylindric part 48a is fixed with the spline state with respect to lower house 20.The situation of this structure, bearing holder (housing, cover) 48 and the lower house 20(closure casing 18 used by spline) constitute bearing holder (housing, cover) of the present invention.In addition, the end face 48e of the bearing holder (housing, cover) 48 used of spline constitute keep one-way clutch 43(housing 44) retaining part.
As mentioned above, the bearing holder (housing, cover) of being used by spline 48 is formed whole (that is: the end face 48e of the bearing holder (housing, cover) of being used by spline 48 keeps the housing 44 of one-way clutch 43) with the housing 44 of one-way clutch 43 and bearing 32, thus, it is the direction of rotation rotation of rotary barrel 13 during along dehydration that one-way clutch 43 allows dehydrating shafts 24, and the opposite direction of direction of rotation is rotated when stoping with dehydration.Herein as Fig. 1 and shown in Figure 4, between the flange 47 of the barrel 48c of the bearing holder (housing, cover) 48 that spline is used and the housing 44 of one-way clutch 43, be provided with plurality of gaps, and between housing 44 peripheries of the through hole 48d of the end face 48e of the bearing holder (housing, cover) 48 that spline is used and one-way clutch 43, also be provided with plurality of gaps.Owing to these gaps (radial clearance), can realize the aligning (so-called centering) of one-way clutch 43 smoothly, can assemble at an easy rate.In addition, the flange 47 of the housing 44 of one-way clutch 43 is held between following and bearing 32 top of the end face 48e that remains on the bearing holder (housing, cover) 48 that spline uses, and constituting above-below direction promptly axially can have some move (that is: being provided with plurality of gaps between end face 48e and the flange 47 and between flange 47 and the bearing 32).Like this, because each above-mentioned gap, during work, one-way clutch 43 can cushion the power that is subjected to.
Below, the effect of said structure is described.At first, when washing or rinsing (washing), braking belt 41 is clamped on the brake drum 27, and rotary barrel 13 is in on-position.In this state, stirring body 14 by motor 15 just, contrary direction drives rotation.Like this, at stirring body 14 just, during the rotation of contrary direction, produce the eddy current current in the rotary barrel 13, wash and washed thing, rotary barrel 13 be subjected to from the eddy current current or along with the quilt of eddy current flow wash thing just, backward revolving force.Now if rotary barrel 13 is subjected to and the equidirectional revolving force of direction of rotation when dewatering, then because this direction of rotation is the tight directions of stopping for braking belt 41, so braking belt 41 is pressed on the brake drum 27 very tightly, to the great brake force of dehydrating shaft 24 effects, thereby stop rotary barrel 13 to equidirectional rotation.
In addition, during the revolving force of the direction that direction of rotation is opposite when rotary barrel 13 is subjected to and dewaters, because this direction of rotation is a slack-side for braking belt 41, so reduced owing to brake the brake force of 41 pairs of dehydrating shafts 24 of belt, rotary barrel 13 can be with above-mentioned direction rotation sometimes.At this moment, if rotary barrel 13 rotates with above-mentioned direction, then because its direction of rotation is spline directions for one-way clutch 43, so therefore the rotation of dehydrating shaft 24 and then prevention rotary barrel 13 can stop above-mentioned rotation effectively.
This structure according to present embodiment, the bearing holder (housing, cover) 48 that spline is used is entrenched in respectively with the state of spline on the housing 44 of periphery of the periphery of bearing 32 of supporting dehydrating shaft 24 and one-way clutch 43, thus, because the housing 44 of one-way clutch 43 and then be as the structure that stops outer shroud 45 rotations, so assembling operation is very simple, only need from sequentially chimeric each parts of top beginning.Therefore, different with former structure (with reference to Figure 13), can not need to be the fixing step-like bolt of one-way clutch 43 peripheries (housing 44 and outer shroud 45), also not need the operation of clamping bench scalariform bolt simultaneously, so can improve the efficient of assembly working significantly.Because do not need step-like bolt, so also there is no need to be provided with and hold the space that step-like bolt is used, the shape of the lower house 20 of block bearing 32 was compared (with reference to Fig. 6) with former structure, can make simpler shape, easily its lower house 20 was carried out the operation of deep-draw processing.In addition, because there is no need to be integrally formed in the big flange that the step-like bolt on the housing 44 of one-way clutch 43 is used, the shape of the housing 44 of one-way clutch 43 can be very simple, so mould etc. is simple in structure, is easy to make.Therefore, present embodiment was compared with former structure, can reduce manufacturing cost.
In addition, because the periphery of the flange 47 of the housing 44 of one-way clutch 43 is made the polygonal shape, and the cross section of the barrel 48c of the bearing holder (housing, cover) 48 that spline is used also makes the polygonal shape, both are chimeric and form to stop the concrete structure of housing 44 rotations of one-way clutch 43, so simple in structure and reliability is high.Again because between the inner surface of the barrel 48c of the periphery of the flange 47 of housing 44 and the bearing holder (housing, cover) 48 that spline is used, be provided with the gap (radial clearance) that aligning is used, hinder so can prevent the aligning of the one-way clutch 43 that scale error and rigging error because of each structure member cause effectively.In addition, except above-mentioned gap, between the end face 48e of the flange 47 of the housing 44 of one-way clutch 43 and the bearing holder (housing, cover) 48 that spline is used and between above-mentioned flange 47 and bearing 32, also be provided with plurality of gaps (end play), above-mentioned housing 44 can a little be moved vertically, so when one-way clutch 43 work, can cushion the suffered power of one-way clutch 43.
In the structure in the past, as shown in figure 14, also on the installation position of step-like bolt 9, be provided with radial clearance a, be provided with end play b simultaneously.But, former structure, accurately the work of control gap a, b is quite difficult.With respect to former structure, in the above-described embodiment, because the housing 44 of one-way clutch 43 and bearing holder (housing, cover) 48 that spline is used all are the structures of processing easily, so the adjustment in each gap is very simple.
