The specific embodiment
As shown in Figure 2, washing machine rotary shaft support structure provided by the invention comprises rotating shaft 10, shell the 20, the 1st bearing 40 and the 2nd bearing 30.Wherein, rotating shaft 10 can transmit the revolving force of motor to not shown cylinder; But shell 20 supporting rotating shafts 10; The 1st bearing 40 and the 2nd bearing 30 then are clipped between shell 20 and the rotating shaft 10, and it can make rotating shaft 10 cunnings rotate soon.In addition, the contact-making surface both side ends that the 1st bearing 40 and the 2nd bearing 30 lay respectively at rotating shaft 10 and shell 20 to be supporting rotating shaft 10, and can make that rotating shaft 10 is sliding to rotate soon.One end of rotating shaft 10 is the motor side link 11 that links to each other with motor, and the other end then is the cylinder side link 12 that joins with cylinder.In addition, in the present invention, be inserted with the elastomer 34 that can absorb vibration between the outer circumference surface of the inner peripheral surface of bearing 40,30 and rotating shaft 10.Elastomer 34 can be absorbed in the vibration that produces on the contact-making surface of bearing 40,30 and rotating shaft 10, so the vibration that when collision produces between bearing 40,30 and the rotating shaft 10 just can not passed to the outside.And, bearing 40,30 and the contact-making surface of shell 20 on also can insert elastomer, but because bearing 40, the 30th, force to be pressed into and be fixed on the inside of shell 20, and shell 20 do not rotate, thereby at bearing 40,30 and the contact-making surface of shell 20 on just can not produce vibration, so seldom sandwich independent elastomer between them.But the present invention not eliminating sandwiches elastomer between bearing 40,30 and shell 20.That is, the interior ring of bearing 40,30 be pressed into fixing and outer shroud for the state that inserts that slides under, should sandwich elastomer between bearing 40,30 and the shell 20.In addition, because the 1st bearing 40 and the 2nd bearing 30 lay respectively at the contact site both side ends of rotating shaft 10 and shell 20, therefore can further improve the effect that absorbs vibration.Specify the structure of elastomer 34 below.Because the 1st bearing 40 is identical with the structure of the 2nd bearing 30, therefore a position only is described here, another position can be with reference to explanation thereafter.As shown in Figure 3 and Figure 4, be inserted with the 2nd bearing 30 between rotating shaft 10 and the shell 20.The 2nd bearing 30 is made of interior ring 33, outer shroud 31 and ball 32.Wherein, interior ring 33 contacts with rotating shaft 10, and outer shroud 31 contacts with shell 20, and ball 32 then is clipped between interior ring 33 and the outer shroud 31.In addition, can also be provided with on the 2nd bearing 30 not shown can make ball 32 be supported in ball grooves between ring 33 and the outer shroud 31.In addition, on rotating shaft 10 outer circumference surfaces at the position that contacts with interior ring 33, be formed with the groove 35 of recessed certain depth, elastomer 34 is installed in the groove 35.Elastomer 34 can be absorbed in the vibration that produces on rotating shaft 10 and interior ring 33 contact-making surfaces, and it is for sandwiching the annular element in the groove 35, so also can be referred to as O type ring.And in order to absorb vibration effectively, elastomer 34 need be made of elastomeric material.In addition, for the ease of machined grooves 35, recessed groove 35 should be positioned at the outer surface of rotating shaft 10.If groove 35 is positioned on the ring 33, in sandwiching, can't fix behind the groove 35 of ring on 33 on elastomer 34, additional work such as it is fixing to adhere, and also very inconvenient during operation, so can not adopt this scheme.As shown in Figure 4, be center and from inside to outside be provided with elastomer 34, interior ring 33, ball 32, outer shroud 31 and shell 20 successively with rotating shaft 10.So when rotating shaft 10 rotations, the vibration that produces between rotating shaft 10 and the interior ring 33 just can be absorbed by elastomer 34.According to the present invention, when rotating shaft rotated, the running between rotating shaft and the bearing was different with the running of existing structure, so it can reduce issuable vibration effectively.
