Fig. 2 is the partial perspective view of non-contact type bearing embodiment of the present invention.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described:
A kind of non-contact type bearing, including bearing outer ring 1, bearing inner race 2, retainer 3 and ball 4, described ball 4 is fixed on bearing outer ring 1 by retainer 3
And between bearing inner race 2, it is respectively equipped with on described bearing outer ring 1 and bearing inner race 2 and is available for the first raceway 5 and the second raceway 6 that ball 4 rolls, the bearing cap 7 being respectively provided on two sides with annular between described bearing outer ring 1 and bearing inner race 2, all fixing with the bearing inner race 2 inwall matched in clearance being connected with bearing outer ring 1 of described bearing cap 7, cleaning the first raceway 5 and cleaning plant 8 of the second raceway 6 it is equipped with on retainer 3 between described adjacent ball 4, described cleaning plant 8 includes Rotational Cylindrical 81, what described Rotational Cylindrical 81 rotated is arranged in retainer 3, it is arranged with gear in described Rotational Cylindrical 81
82, the inner face of described arbitrary bearing cap 7 is provided with the face gear 9 driving Rotational Cylindrical 81 to rotate, described gear 9
Being meshed with gear 82, the first raceway 5 and hairbrush 83 of the second raceway 6 is cleared up in being respectively arranged at two ends with of described Rotational Cylindrical 81.Described retainer 3 includes support body 1 the most ringwise and support body 2 32, described support body 1 and support body 2 32 all include ring 1 and ring 2 11, described ring 1, ring 2 11 are all tangent with ball 4, it is provided with connecting plate 12 between described two rings 1, connecting plate 12 is bolted with ring 1 and ring 2 11 respectively, it is provided with connecting plate 12, described Rotational Cylindrical between described two rings 2 11
81 are located in two connecting plates 12 rotationally, are provided with two rolling members 13 of fixing ball 4 between described two rings 2 11.It is provided with connecting rod 14 between described ring 1 and ring 2 11.Described rolling member 13 includes connecting support body 1 and the rotating shaft 131 of support body 2 32 and the cylinder 132 that can rotate in rotating shaft 131, and described rotating shaft 131 is threadeded with support body 2 32 with support body 1 respectively, described connecting rod 14
Threaded with ring 2 11 with ring 1 respectively.
By using technique scheme, after bearing rotates, all fixing with the bearing inner race 2 inwall matched in clearance being connected with bearing outer ring 1 of bearing cap 7, bearing cap 7 can be driven after so bearing inner race 2 rotates to rotate, the inner face of arbitrary bearing cap 7 is provided with the face gear 9 driving Rotational Cylindrical 81 to rotate, such Rotational Cylindrical
81 just can do circumferential movement self with retainer can also rotate the impurity making hairbrush 83 rotate in cleaning the first raceway 5 and the second raceway 6, make impurity cleaned to outside the first raceway 5 and the second raceway 6, thus it is possible to prevent contaminating erosion the first raceway 5 and the second raceway 6, clears up cleaner.It is provided with two rolling members 13 of fixing ball 4 between two rings 2 11, which reduces ball 4 and retainer 3
Between friction, bearing is made to be difficult to heating, extend the service life of bearing, because being equipped with rolling member 13 between adjacent two balls 4, so that the ball 4 in whole bearing all links together, can realize rolling together and stop together, enhance whole antiwhip, retainer 3 includes support body 1 the most ringwise and support body 2 32, support body 1 and support body 2 32 all include ring 1 and ring 2 11, such material arranging minimizing retainer 3, reduces production cost.Ring one
It is provided with connecting rod 14 between 10 and ring 2 11, makes retainer 3 more firm, make bearing more steady running when.Rotating shaft 131 is threadeded with support body 2 32 with support body 1 respectively, connecting rod 14 is threadeded with ring 2 11 with ring 1 respectively, so mounting or dismounting very easily can unload retainer 3, if and when certain parts damages of retainer 3, as long as it is the most permissible to replace which parts, economic and environment-friendly.
