The specific embodiment
Below with reference to Fig. 3, Fig. 4, an embodiment of the pulley of roller washing machine of the present invention is elaborated.
Fig. 3 demonstrates the oblique view of pulley of the present invention.Fig. 4 is the back side oblique view of Fig. 3.
As shown in the figure, roller washing machine of the present invention includes following structure: body 100, sink 101, motor 103, cylinder 2, pulley 105, pendulum spring 109 and brake 110.
Roller washing machine possesses above-mentioned body 100 is arranged; Above-mentioned sink 101 is arranged on the inside of above-mentioned body 100, has been integrally formed therewith electric machine support on the outer peripheral face of above-mentioned sink 101; Above-mentioned motor 103 is installed on the electric machine support of above-mentioned sink 101; Above-mentioned cylinder 2 can be arranged on the inside of above-mentioned sink 101 rotatably; Above-mentioned pulley 105 is by (drawing) machine-shaping that iron plate is stretched, 105 rears that are attached at above-mentioned cylinder 2 of above-mentioned pulley; Above-mentioned pendulum spring 109 is arranged between above-mentioned body 100 and the sink 101, is used for above-mentioned sink 101 is suspended on the inboard of above-mentioned body 100; Above-mentioned brake 110 is arranged on the above-mentioned sink 101, is used to weaken the vibrations of above-mentioned sink 101.
Above-mentioned pulley is to be processed to form the shape that is roughly cup by stretch (drawing); Above-mentioned pulley 105 includes following structure: be made of rear surface 105a and side wall surface 105b.The central authorities of above-mentioned rear surface 105a have the hub 105c that drum shaft 111 is inserted; Above-mentioned side wall surface 105b is integrally formed therewith in the vertical direction of above-mentioned rear surface 105a, the lateral surface contact conveyer belt 106 of above-mentioned side wall surface 105b.
In addition, the middle body of above-mentioned rear surface 105a inserts the hub plate 120 that (caulking) is combined with identical material, and above-mentioned hub plate 120 is used for the intensity that reinforced company has drum shaft 111 positions.
In addition, the side wall surface 105b front end of above-mentioned pulley 105 is improved rounding (rounding) processing of intensity, handle by above-mentioned rounding, when pulley rotates at a high speed, not only can correctly keep original shape of above-mentioned pulley 105, and in operation, bring safety to the user.
At this moment, preferably laterally direction the side wall surface 105b front end of above-mentioned pulley 105 carried out rounding handle.
Below, the effect of the pulley of roller washing machine of the present invention with said structure is elaborated.
At first, the pulley 105 of roller washing machine of the present invention is that iron plate is processed to form by a kind of stretching (drawing) processing method in the processing method for stamping, unlike the prior art:, when dehydration, can prevent the resonance noise of limited slip wheel and conveyer belt owing to removed the relief thing that is formed on the hub portion lateral surface.
That is to say, though the pulley 105 of prior art is that purpose is formed with a plurality of relief thing 105d with the bulk strength that improves pulley on wall 105a thereafter, because above-mentioned a plurality of relief thing 105d make the intrinsic frequency of the intrinsic vibration frequency of conveyer belt and pulley consistent in certain speed scope (approximately 600-1300RPM) when rotating at a high speed, can cause the problem that covibration produces abnormal sound, but on rear surface, do not form the relief thing in the present invention when processing above-mentioned pulley 105, can avoid the consistent phenomenon of frequency band, so can prevent abnormal sound because of the generation of factors such as above-mentioned conveyer belt 106 vibrations.
On the one hand,, the middle body of above-mentioned rear wall 105a is combined with hub plate 120, so can reinforced company have the intensity of axial region position because inserting (caulking).
That is to say have the position rear surface 105a middle body of above-mentioned drum shaft 111 that two plates are stacked formation owing to link, so can strengthen the intensity of middle body.
In addition, because the side wall surface 105b front end to pulley 105 of the present invention has carried out the rounding processing laterally, improved the intensity of pulley 105, thus when rotating at a high speed, not only can correctly keep the original shape of pulley 105, and make smooth surface can guarantee operator's security.
Up to the present, though be that the center has been described in detail with embodiments of the invention, the present invention is not limited to the foregoing description, can propose a lot of distortion to the shape that do not break away from basic fundamental thought category of the present invention and material etc.
