Description
Technical field
The utility model relates to a kind of axle and bearing unit structure, is widely used in various mechanical manufacturing field.
Background technique
Axle is widely used in mechanical manufacturing field with bearing, and the major function of bearing is the part on supporting axle and the axle, and the running accuracy of retainer shaft, to reduce the friction and wear between rotating shaft and the supporting.According to the frictional property of supporting place relative motion surface, bearing is divided into sliding bearing and rolling bearing, and general said bearing is commonly referred to as rolling bearing.
The basic structure of rolling bearing generally is made up of inner ring, outer ring, rolling element and retainer, wherein the effect of inner ring is to match with axle and rotate together with the axis, the outer ring effect is to match with bearing support, play a supportive role, rolling element is rolling element to be distributed between inner ring and the outer ring uniformly by means of retainer, retainer can make rolling element evenly distribute, and prevents that rolling element from coming off, guiding rolling element rotation lubricate.
In order to increase the bulk strength of bearing, need the single bearing more than two is cascaded successively to form whole bearing unit, the solid bearing assembly that comprises a rolling bearing is encased on the axle, its load mode can be by pushing assembling, or from this a end bearing unit is packed into.
When being installed in above-mentioned solid bearing assembly on the bearing support, the big young pathbreaker of mounting hole directly has influence on the working life of bearing unit on the bearing support, because of the external diameter of bearing unit needs just in time cooperate with the mounting hole of bearing support, do not allow between the two because of existing the gap to shake, so that the axle and the appended part thereof that connect can be because of damages such as wearing and tearing, fatigues, and the vibration and the noise of reduction one-piece element, to increase the working life of bearing unit; Like this with regard to relative increase the difficulty of processing of bearing support, and the installation difficulty between bearing and the bearing support, when especially in the environment of bearing support off-centre, using, the difficulty of processing of bearing support is bigger, secondly, in the process of changing bearing, bearing support needs to change because of damaging in dismounting too, so this kind structure is unsuitable for producing in enormous quantities.
Summary of the invention
Technical problem to be solved in the utility model is the defective of inconvenience being installed in order to overcome between the bearing support processing difficulties that exists in the prior art and bearing and the bearing support, and a kind of axle and bearing unit be provided, this and bearing unit can reduce the machining accuracy of bearing support, improve the working life of bearing simultaneously, make convenient installation the between bearing unit and the bearing support, and ensure the precision of assembling.
Be achieved in that a kind of axle and bearing unit for solving the problems of the technologies described above the technical solution of the utility model, comprise running shaft 1, bearing unit 2, bearing cap 4 and be provided with the bearing support 3 of indent bearing mounting hole 31; Bearing unit 2 is installed in the mounting hole 31 of bearing support 3, and is tight by bearing cap 4 lids; It is characterized in that: described bearing unit 2 is made of two bearing part at least, and each bearing part is set on the running shaft 1 successively, is equipped with positioning block 5 between bearing part; Be provided with the step 32 that matches with the outer ring of bearing unit 2 in described bearing support 3 mounting holes 31.
The external diameter of described positioning block 5 is less than the internal diameter of bearing support 3 mounting holes 31, and its internal diameter is less than the outer ring internal diameter of bearing unit 2.
Described bearing unit 2 is positioned at the upper end of running shaft 1.
Described running shaft 1 is provided with and prevents that bearing unit 2 breaks away from this restricting means.
Described restricting means is that running shaft 1 is at the formed shaft shoulder 12 in bearing unit 2 lower ends.
Described bearing unit 2 is positioned on the running shaft 1 by a clasp 7.
Described bearing cap 4 is a lid formula structure, and integral body is pressed in the lower end of bearing unit 2, and running shaft 1 passes bearing cap 4, is connected by screw between bearing cap 4 and the bearing support 3.
Described bearing cap 4 is provided with a bearing hole, is provided with the step 41 that matches with the outer ring of bearing unit 2 in this bearing hole.
Described bearing cap 4 parts are pressed in the lower end of bearing unit 2, and are connected by screw between bearing cap 4 and the bearing support 3.
Described positioning block 5 is a cirque structure.
The beneficial effects of the utility model, the utility model has overcome the difficulty of processing of bearing support, and the technological problems of the installation difficulty between bearing and the bearing support, because of the utility model bearing unit adopts split type, positioning block all is installed between bearing part, do not need between the mounting hole of bearing support and the bearing unit like this to closely cooperate, as long as can put into mounting hole 31 to bearing unit 2, again by the positioning block 5 between the bearing part, step 32 and bearing cap 4 on the bearing support 3 are fixed bearing unit 2, make bearing unit 2 transverse movement or shaking phenomenon can not occur, easy for installation; Simultaneously, bearing support processing is simple, also can one shape, and reduces processing cost, improves the yield rate of product.
Because of the lower end of bearing unit is equipped with bearing cap, make the integral body of bearing unit play can not take place, even under the working state of high speed rotating, also can avoid effectively breaking away from the generation that causes Bin go because of bearing unit.
The utility model compact structure, in light weight, axial dimension more dwindles; The precision height, the rotating speed height, it is little to wear and tear, long service life; Be applicable to production in enormous quantities, steady quality is reliable, the manufacturing efficiency height.
