As Fig. 1 and shown in Figure 4, bearing support 6 comprises axle sleeve 6a and attic base 6b, and supports by 5 pairs of rotating shafts 2 of bearing, and bearing 5 is supported by axle sleeve 6a itself.Attic base 6b extends to the neighboring area that comprises air outlet 7 openings around axle sleeve 6a substrate, and utilizes bolt 11 to be connected and fixed from the back side on the backside openings 1a of urceolus 1.Like this, attic base 6b fixes the stator 4a of motor 4 by bolt 12.Attic base 6b is at a 6c of excision portion that avoids air outlet 7 and the back is exposed of circumference.The 6c of excision portion is the connection in order not hinder circulation air-supply loop to come from the back of air-supply side.
Axle connection support part part 8 side from the outside abuts in the bottom opening 3a place of swing roller 3.Here, axle connection support part part 8 links with a end by the rotating shaft 2 of 5 supportings of bearing, and on a plurality of positions of circumference from the outside side utilize bolt 14 to be fixed on the fuselage and the chimeric barrel 3b in bottom of swing roller 3, a bottom opening 3a and an axle connection support part part 8 are become one.Rotating shaft 2 at one end is provided with flange 2a, and utilizes bolt 15 to be fixed on the connection support part part 8, thereby rotating shaft 2 and axle connection support part part 8 are connected as a single entity.
Fig. 5 is mounted on the back of this tumbling-box washing machine urceolus, be used for the stereogram of seeing the bearing support that motor stator is installed from the front of the bearing of supporting rotating shaft.Fig. 6 is the stereogram that Fig. 5 bearing support is seen from behind.
As mentioned above, the swing roller 3 in the rolling washing dryer 100 is by resiliency supported, and urceolus 1 is to support with existing bracing or strutting arrangement basically, and drives with existing drive unit.The axle sleeve 6a and the attic base 6b that comprise spring bearing 5 in the bearing support 6.
The 6c of excision portion is arranged on the attic base 6b, followed for not hindering and circulate the loop-coupled existing grown form of air-supply.But, be provided with in the circumference both sides of the 6c of excision portion as Fig. 3 to shown in Figure 6 almost towards radial enhancing radially and that almost be in the shape of the letter V portion 21.Therefore, swing roller 3 is when rocking rotation, on the part of circumference, can share and bear the radially high bend loading of the attic base 6b circumference both sides that act on the 6c of excision portion, be created in the large-area maximum stress of the 6c of excision portion thereby can disperse to alleviate, and the distortion of the crooked and attic base 6b of inhibition rotating shaft 2.
This means by be provided with volume that radial enhancing portion 21 strengthens required portion increase can with have only little stress in action the volume of part reduce to cancel out each other.Thereby this also can think to utilize the component of different stress distribution to move the method that strengthens bearing support 6.
Here so-called radial enhancing portion 21 is meant, when overlapping with common radial reinforcement 22, it such as prolongs, thickens, highly increases at structure that has an enhancing at least, and the situation that it is made up is also arranged.In Fig. 5 and Fig. 6, common radial reinforcement 22, cyclic reinforcing rib 23, along the profile position reinforcement 24 of profile, around the compound settings such as box-shaped reinforcement 28 of the installing hole 30,31 of attic base 6b periphery, and compare with it and also to have strengthened thickness, as radial enhancing portion 21.
According to above modification method, in bearing support 6, rocking excision portion 6c both sides that when rotation produce load at swing roller 3 has excessive maximum stress place to be provided with radial enhancing portion 21.Radial enhancing portion 21 can share in the circumference part bears the high load capacity that produces because of high flexibility.Therefore, when swing roller 3 rocks rotation, can disperse and alleviate the maximum stress that on excision portion 6c both sides large tracts of land, produces, and can suppress the distortion of the crooked of rotating shaft 2 and attic base 6b.Because that has improved swing roller 3 rocks swing, vibration and noise, so can further make and run up and obtained prolongation in service life of high loaded process.And, the partial volume that strengthens required part increase with have only little stress in action the partial volume of part reduce and can cancel each other.Like this, the problem that the enhancing of bearing support causes weight to strengthen also can move by volume and prevent, compares existing design and also can suppress the also problem of corresponding increase of the volume that brings because of the rotating speed high speed.
In addition, near radial enhancing portion 21 is located at and extends to attic base 6b periphery from axle sleeve 6a.Radial enhancing portion 21 extends outer circumferential side from axle sleeve 6a, produces the consistent footpath of attic base 6b deformation directions upwards with rotating shaft 2 swings, can strengthen to the distortion terminal from its distortion substrate.Therefore, on circumference, share and having born to the crooked of the rotating shaft 2 of the 6c of excision portion side and to rotating shaft 2 crooked generation attic base 6b bend loading radially.And the dispersion of the big stress of the attic base 6b from axle sleeve 6a to periphery and alleviate the periphery position that acts on attic base 6b.Its result can suppress the distortion to the crooked and rotating shaft 2 crooked generation attic base 6b of the 6c of excision portion sidespin rotating shaft 2 better.
And attic base 6b goes up the connection enhancing portion 25 that the radial enhancing of also promising connection portion 21 extends.Connect enhancing portion 25 and do not form protruding circular-arcly towards axle sleeve 6a, but being approximately of connecting between the radial enhancing portion 21 of the reinforcement that is in the shape of the letter V is A font reinforcement.Therefore, connection enhancing portion 25 has constituted the box enhancing of triangle portion 26 from the axle sleeve 6a side of the 6c of excision portion to axle sleeve 6a.Follow the enhancing of box structure, the intensity of this scope also strengthens thereupon.
In addition, connect enhancing portion 25 and both improved to the crooked of the rotating shaft 2 of the 6c of excision portion side and for the intensity that radially bends because of rotating shaft 2 crooked generation attic base 6b, again can be to the planar section dispersive stress of the non-reinforcement shape of A shape reinforcement position and encirclement thereof.Its result can further reduce maximum stress value, suppresses the distortion of rotating shaft 2 to the crooked and attic base 6b of the 6c of excision portion side better.
Connect enhancing portion 25 and then form the curved shape of convex along the axle sleeve 6a side profile of the 6c of excision portion in axle sleeve 6a side.Therefore, increase at the axle sleeve 6a side profile of the 6c of excision portion and the axle sleeve 6a side that connects enhancing portion 25 excision area, and strengthen at the opening of its part with air outlet 7 because of the curved shape excision 6c of portion of convex.Consequently can not increase the air-supply load and increase the wind pushing air amount, and improve drying speed.And,, can improve radial enhancing portion 21 radially the anti-bent toughness of attic base 6b on around the axle sleeve 6a side excision 6c of portion because of being the solid shape for radially.
As shown in Figure 4, when 21 left-hand tools axles, 2 6c of excision portion of the radial enhancing in excision portion 6c both sides portion slant tiltedly distortion, be squeezed in the distortion that load can prevent attic base 6b that radially bends that urceolus 1 back side brings for attic base 6b.For the 6c of excision portion, rotating shaft 2 is when the opposition side diagonal distortion, and the radial enhancing in excision portion 6c both sides portion 21 utilizes attic base 6b external peripheral zone to be the leverage of fulcrum, produces extruding force to urceolus 1 back.Because shown in Figure 5 radial balanced enhancing portion 27 high bending strengths, share in the circumference part and born the extruding force that the crooked and attic base 6b that causes rotating shaft 2 6c of excision portion sides radially bends load.Therefore, even also can disperse and alleviate and the equal maximum stress of the 6c of excision portion side at opposition side for the 6c of excision portion.Radial balanced enhancing portion 27 is by the radial enhancing in 6c both sides portion of excision portion 21 and be symmetrical in the reinforcement that almost is anti-V-arrangement around rotating shaft 2 axis and constitute.It is the reinforcement that is similar to X-shaped at center that radial balanced enhancing portion 27 forms with rotating shaft 2 axis with radial enhancing portion 21.
Consequently, strengthen attic base 6b and bring high load capacity for the position that forms point-symmetric attic base 6b, but share by radial balanced enhancing portion 27 in the circumference part by the radial enhancing portion 21 of excision portion 6c both sides.Therefore, the maximum stress on the point symmetry position can and alleviate to the circumference dispersion.And, for the axle sleeve 6a with attic base 6b be the opposition side of the 6c of the excision portion side of boundary and the 6c of excision portion can realize maximum stress in the dispersion of circumference, alleviate with the equilibrium of stress value, alleviate.Its result can fully prevent the distortion of the diagonal distortion and the attic base 6b of rotating shaft 2.
As shown in Figure 6, the 6c of excision portion is formed with the open profile that is similar to C shape in the periphery of attic base 6b.Because the 6c of excision portion of attic base 6b has been by having excised the coupling part of the attic base 6b outer circumferential side that is open-work under the existing form, thereby offset the part that volume increases takes place for enhancing.Such volume reduce by according to the thickness that reduces to reduce attic base 6b, the minimizing of distributed stress value or delete common radial reinforcement 22, cyclic reinforcing rib 23, along the thickness of the outline portion reinforcement 24 of profile, box-shaped reinforcement 28 etc. or highly carry out.
In addition, the installing hole 31a that is provided with of the open end of the end of radial enhancing portion 21 under the 6c of excision portion open end section 6c1 and the excision portion 6c adjacent with circumference are between the installing hole 31b of an opposite side.Like this, between installing hole 31a, installing hole 31b, be expected to disperse or reduce the stress that produces because of radially big anti-bending strength.The undercapacity of installing hole 31a, installing hole 31b can replenish by connecting attic base 6b periphery to the connection at urceolus 1 back and from both sides, and the open end section 6c1 of the 6c of excision portion is also strengthened.Open end section 6c1 is provided with the enhancing portion 32 that thickens that the other parts that link than radial enhancing portion 21 have thickened, and has the enhancing portion 33 of the profile enhancing portion 34 that a place thickens at least than other parts outline portion reinforcement 24.Therefore, the stress under radial enhancing portion's 21 further dispersions and minimizing open end section 6c1 can prevent distortion or the damage of open end section 6c1.
In addition, the enhancing portion 33 of excision portion 6c both sides combines with radial reinforcement 22.Radial enhancing portion 21, the radial reinforcement 22, the enhancing portion 33 that are adjacent have constituted leg-of-mutton box enhancing portion.Owing to be box structure, increased intensity in the circumference both sides of the 6c of excision portion, improved the intensity that radially bends of attic base 6b, disperse, reduced stress.Axle connection support part part 8 is subjected to high load capacity when swing roller 3 rocks rotation, so axle connection support part part 8 as Fig. 1, Fig. 2 A, shown in Figure 4, is connected with the axle linking part 8a of rotating shaft 2 in central authorities.Axle connection support part part 8 also comprise from axle linking part 8a be installed in radial extension a plurality of radial arm 8b on the bottom plate of swing roller 3, with midway being connected of radial arm 8b, and connection is entrenched in the annular sealing plate 8c of swing roller 3 bottom opening 3a.Each end of radial arm 8b utilizes bolt 14 to be fixed on the fuselage and the chimeric barrel 3b in bottom of swing roller 3.
Moreover irrelevant with intensity, shown in Fig. 2 A, guard 9 abuts on swing roller 3 bottom openings from rear side with axle connection support part part 8, and uses bolting.Like this, guard 9 is clamped between swing roller 3 bottoms and the axle connection support part part 8.So guard 9 independent installation constitutions have not just needed.In addition, guard 9 can be the bottom that aeration portion is arranged at swing roller 3.Consequently resinous guard 9 has reduced in the shared ratio in the bottom of metal swing roller 3, and the metal covering of swing roller 3 bottoms exposes than increasing, and in the texture that improves swing roller 3 bottoms, resinous guard 9 also is not easy to sustain damage.

Shown in Fig. 2 A, the axle connection support part part 8 of swing roller 3 bottom center and the bolting portion of rotating shaft 3 are in order firmly to be connected, so used a plurality of king-bolts 15.The wire netting 43 that uses screw 4 that the front is distributed is fixed on the linking part 8a, hides bolt 15 thereby cover.The projection 8g that axle connection support part part 8 will be arranged at radial arm 8b is entrenched on the spline hole 3d of swing roller 3 bottoms and forbids rotating.In addition, guard 9 is owing to the spline hook portion 51 of the concaveconvex shape between the axle linking part 8a of guard 9 and axle connection support part part 8 forbids rotating.
Figure 11 is half a part stereogram of seeing this rolling washing dryer axle connection support part part from the front.Figure 12 is half a part stereogram of seeing this rolling washing dryer axle connection support part part from the back side.
The present invention as shown in figure 11, axle connection support part part 8 is between radial arm 8b substrate, for extending to the expansion of the edge, open end of urceolus 1 side umbrella from the side periphery front end of axle linking part 8a, it is integrally formed and strengthen that the solid that connects into the web shape between the substrate of adjacent radial arm 8b strengthens connecting portion 8e.Therefore, the high load capacity the during diagonal distortion of rotating shaft 2 can well disperse and absorb around the linking portion of rotating shaft 2.And the maximum stress majority that concentrates on rotating shaft 2 is reduced, and only produces little stress on axle connection support part part 8.
Be exactly that axle connection support part part 8 becomes the centre that a linking part 8a bears swing roller 3 rotating shaft 2 crooked loads of generation when rocking rotation specifically.The crooked load of rotating shaft 2 is delivered to the installation portion of rotating shaft 3 through the linking part of annular sealing plate 8c formation from the substrate of radial arm 8b.Three-dimensional strengthen the weight that connecting portion 8e does not increase axle connection support part part 8 especially, but and the side periphery of axle linking part 8a between to urceolus 1 side the box-shaped of opening is arranged.So axle 8 pairs of bending strengths of connection support part part and rotating shaft 2 crooked moves the transverse strength that causes towards circumference and is improved.In addition, 8 substrates at radial arm 8b of axle connection support part part have alleviated the crooked of rotating shaft 2, can keep can not producing big stress to the mounting portion of rotating shaft 3.That has consequently reduced rotating shaft 3 rocks rotation, vibration and noise, has improved the durability of axle connection support part part 8.
Shown in Fig. 2 B, three-dimensional strengthen connecting portion 8e as shown by arrows for making, pass through the sector region 9d of guard 9 dispersedly while spread from the air-supply of the air outlet 7 of urceolus 1, make the shape of longshore current to bending, distortion or the inclination of rotating shaft 3 central sides.That is the expanded configuration that strengthens the edge, open end of connecting portion 8e to solid can be curved shape, distorted shape or tilted shape.
Like this, the easier central side of air-supply towards swing roller 3.Therefore, the not enough situation of central portion more can improves drying efficient compared with the air-supply of 3 peripheries of swing roller in the prior art is too much.The open end edge shape that strengthens connecting portion 8e urceolus 1 side towards solid can be the mouth edge shape of corresponding air outlet 7 pivot sides.As Fig. 5 and shown in Figure 6, the three-dimensional connecting portion 8e that strengthens is to almost corresponding to the shape of the pivot side expansion of the distorted shape of the connection enhancing portion 25 of the 6c of excision portion.That is: the inner periphery of rotating shaft 2 sides of the edge, open end of three-dimensional enhancing connecting portion 8e and air outlet 7 can bend to convex in rotating shaft 2 sides.
Three-dimensional bending, distortion or the inclination that strengthens connecting portion 8e towards preferably corresponding to the mouth marginal position of the pivot side of air outlet 7.The three-dimensional angle of inclination that strengthens connecting portion 8e preferably is about 45 ° for the axis of rotating shaft 2.But not limited by this angle of inclination, the wind-guiding that will be decided to be optimum air outlet 7 by the air supply direction of air outlet 7 towards and comprise from the air supply path in connected circulation air-supply loop radially the wind-guiding in the swing roller 3 towards.In a word, the shape in week is almost consistent on the direction of rotating shaft 2 in the opposition side of the axle linking part 8a of the interior week of annular sealing plate 8c and air outlet 7, and the inner periphery of rotating shaft 3 sides of air outlet 7 is preferably consistent on the direction of rotating shaft 2 with the edge, open end that solid strengthens connecting portion 8e.Thus, between axle linking part 8a and annular sealing plate 8c, distinguish the form in the fan-shaped open air exhaust zone that forms and the air draft zone of big or small corresponding air outlet 7, have the advantage of in urceolus 1, blowing fully from air outlet 7 by radial arm 8b.
As shown in figure 12, three-dimensional enhancing connecting portion 8e is formed with the three-dimensional shape at the open back side between axle linking part 8a outside.As shown in Figure 7, strengthen the shape that each radial arm 8b cross section that connecting portion 8e is connected is the U font with solid, relative with radial reinforcing section 9 back sides of guard 9 can be standby.As shown in Figure 2, the length direction at radial arm 8b erects the connecting plate 8f that forms between the connection biside plate from U font bottom midway.Radial arm 8b has the box structure of 2 connections on its length direction, improved transverse strength and bending strength.
