Description
Technical field
The utility model relates to mechanical bearing technical field, relates in particular to a kind of adjustable thickness bearing.
Background technique
Bearing is the mechanical parts that a kind of mechanical field is conventional, be mainly used in support and the location of rotatable parts, because the bearing of transmission is all standard piece, its thickness and broadband are all reference value, in actual use, when bearing is installed, all need to axle sleeve be installed on axle bearing is positioned, install so also not aspect, also increase the cost of mechanical device.
Secondly, current application more widely bearing has deep groove ball bearing, its guide groove is generally semicircle, and when bearing assemble, described semicircle guide groove and ball are combined closely, yet such setting makes bearing only can bear the thrust load of radial load and trace, when suffering from larger axis and impact to power, bearing is easy to be damaged, and causes the precision of bearing and performance to reduce, meanwhile, also can greatly shorten the working life of bearing.
Summary of the invention
The utility model is for the deficiencies in the prior art, designed a kind ofly can adjust inner ring thickness of two sides, and made bearing can bear the bearing of radial load and thrust load simultaneously, and its concrete scheme is as follows:
The utility model discloses a kind of adjustable thickness bearing, comprise bearing outer ring, bearing inner race and ball, it is characterized in that: described bearing inner race is provided with guide groove, described ball is arranged in guide groove, described guide groove is comprised of the first groove face and the second groove face and the sunk area between two sections of groove faces, between described sunk area and described ball, there is gap, between described ball and described guide groove, there are two corresponding contact positions, such setting, make bearing can bear radial load and thrust load simultaneously, when bearing thrust load, improve more than 2 times than the common deep groove ball bearing life-span.The sidewall of described rotating shaft inner ring is provided with a plurality of tapped holes, also comprise the thickness sheet identical with the diameter of rotating shaft inner ring, on thickness sheet, be provided with the attachment hole corresponding with tapped hole, by set up thickness sheet in bearing inner race, change the thickness of bearing inner race, save the axle sleeve needing while installing, reduce cost, be also convenient to installation, the dismounting of bearing.
As preferably, the top of described attachment hole is provided with countersunk head.
As preferably, described sunk area is arc structure, can be to radial dispersion part load, thus the life-span of improving bearing.
As preferably, described sunk area is del structure, can be to radial dispersion part load, thus the life-span of improving bearing.
As preferably, the number of described ball is 2N, and N is natural number.
As preferably, between bearing outer ring and bearing inner race, be provided with retainer.
The beneficial effects of the utility model are: structure of the present utility model can make bearing can bear radial load and thrust load simultaneously, when bearing thrust load, than common deep groove ball bearing life-span raising 2-3 doubly, and, by set up thickness sheet in bearing inner race, change the thickness of bearing inner race, save the axle sleeve needing while installing, reduced cost, be also convenient to installation, the dismounting of bearing.

Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.Obviously, described embodiment is only part embodiment of the present utility model.
Embodiment 1: as shown in Figure 1, adjustable thickness bearing, comprise bearing outer ring 1, bearing inner race 2 and ball 3, it is characterized in that: described bearing inner race 2 is provided with guide groove 4, described ball 3 is arranged in guide groove 4, described guide groove 4 is comprised of the first cambered surface 41 and the second cambered surface 42 and the sunk area between two sections of cambered surfaces, between described sunk area and described ball 3, there is gap, between described ball 3 and described guide groove 4, there are two corresponding contact positions, such setting, make bearing can bear radial load and thrust load simultaneously, when bearing thrust load, improve more than 2 times than the common deep groove ball bearing life-span.The sidewall of described rotating shaft inner ring is provided with a plurality of tapped holes 5, also comprise the thickness sheet 6 identical with rotating shaft inner ring diameter, on thickness sheet 6, be provided with the attachment hole corresponding with tapped hole 57, the top of described attachment hole 7 is provided with countersunk head 8, by set up thickness sheet in bearing inner race, change the thickness of bearing inner race, save the axle sleeve needing while installing, reduced cost, be also convenient to installation, the dismounting of bearing.
Embodiment 2: as shown in Figure 2, embodiment 2 with embodiment 1 difference is, described guide groove 4 is comprised of the first inclined-plane 41 and the second inclined-plane 42 and the sunk area between two sections of inclined-planes, its shape is as same inverted triangle, can be to radial dispersion part load in when work, thus life-span of bearing extended.
Embodiment 3: as shown in Figure 3, embodiment 3 is to be provided with retainer 9 between bearing outer ring 1 and bearing inner race 2 with embodiment 1 difference, make to keep between ball suitable distance, prevent that adjacent ball from directly contacting, friction and heating can be remained on to floor level, extend the life-span of bearing.
Above-described embodiment is preferably mode of execution of the utility model; but mode of execution of the present utility model is not restricted to the described embodiments; other are any does not deviate from the change of making under Spirit Essence of the present utility model and principle; modify; substitute, combination, simplifies; all should be equivalent substitute mode, all should be included in protection domain of the present utility model.
