Abstract
A universal assembling angle contact ball bearing and making method, which contains strictly controlling diameter deviation of internal and outer ring being in 1/3 of current standard, width deviation in positive and negative 0.5um, context at two ends being equal, contact angle deviation in positive and negative 0.5 degree, radial run out and face run out precision. Said invention can be optionally assembling.
Description
Technical field:
The present invention relates to bearing manufacturing technical field, especially a kind of universal assembled angle contact ball bearing that can match arbitrarily and preparation method thereof.
Background technique:
At present, the structure of common single-row angular contact ball bearing has three kinds of forms: one, outer astragal slope; Two, interior astragal slope; Three, inside and outside circle all is with the slope.This class bearing can bear the thrust load of a radial load and a direction, in the use, usually will install with the bearing coupling of bearing reverse thrust load.In addition, for improving the bearing capacity and the supporting rigidity of bearing, angular contact bearing generally all wants assembly to use, and promptly two covers, three covers even more cover angular contact ball bearings are fitted in together with certain configuration mode and use.
The basic configuration mode of bearing has back-to-back, face-to-face and connect three kinds, as in two cover outer rings during sloping single-row angular contact ball bearing configuration, two sides that do not have a slope are close together to back-to-back; Sloping side is close together to face-to-face; Slope and non-slope are close together and are series connection, and its performance characteristics of different configuration modes is inequality.The matched bearing that present Production of bearing manufacturer provides mainly is that the orientation arrangement mode is main, promptly after Production of bearing manufacturer supplies with the user with bearing with specific configuration mode, putting in order of bearing pack is fixing, the user cannot change putting in order of bearing pack arbitrarily, otherwise, the performance characteristics of bearing pack can change, and will directly have influence on the performance of main frame.Therefore, if the user when Production of bearing manufacturer orders matched bearing, must indicate the concrete configuration mode of required bearing pack, even with a kind of bearing of model, the bearing pack of different configuration modes if desired also must explanation when buying.
Summary of the invention:
For overcoming the above-mentioned defective of existing angular contact ball bearing, the purpose of this invention is to provide a kind of universal assembled angle contact ball bearing and preparation method thereof, the user is when trying out this angular contact ball bearing, only need the identical bearing of the some models of buying, can combine arbitrarily back-to-back, face-to-face or the bearing pack of arbitrary form of connecting.
For achieving the above object, the present invention adopts following technological scheme:
Described universal assembled angle contact ball bearing, it is made up of outer ring, inner ring, rolling element and retainer; It is outer astragal slope that its structure has three kinds of forms a kind of, and a kind of is interior astragal slope, and another kind is that Internal and external cycle all is with the slope; This universal assembled angle contact ball bearing, outer ring and inner ring are made by high-carbon-chromium bearing steel, and rolling element is made by high-carbon-chromium bearing steel or silicon nitride ceramic material, and retainer is by phenolic aldehyde lamination stringing or high molecule plastic material.
Described universal assembled angle contact ball bearing making method:
1) size deviation of the outer diameter D of the inner diameter d of its inner ring and outer ring is controlled in existing respective standard 1/3 scope;
2), the size deviation of the width C of the width B of inner ring and outer ring except that the regulation that satisfies existing respective standard, also must guarantee consistently, the phase mutual deviation between two width values should be controlled at ± 0.5 μ m within;
3), the Deviation Control of wrapping angle a is in ± 0.5 ° of scope;
4), the protrusion amount b at bearing two ends and f equate, and when thrust load F reached predetermined preloading, the Internal and external cycle at bearing two ends was just concordant, i.e. b=f=0;
5), the circular runout of bearing enclose is with existing respective standard compression 1/3;
6), the end face run-out of bearing enclose is with existing respective standard compression 1/3.
For realizing technique scheme, during processing and fabricating, bearing enclose diameter, width, the protrusion amount at bearing two ends, wrapping angle, the circular runout of bearing enclose, the every precision of end face run-out are controlled in strictness; Before the bearing trap, reconditioning protrusion amount at first, this just needs to detect the protrusion amount that will grind off on angular contact ball bearing end face measuring instrument for projection, on precision horizontal surface grinding machine, grind off unnecessary protrusion amount then, and Internal and external cycle processed simultaneously, like this will inner ring, can be made into universal assembled angle contact ball bearing after outer ring, retainer and the rolling element heating trap.
Because adopt aforesaid technological scheme, the present invention has following superiority:
Two cover models, to preload identical universal assembled angle contact ball bearing can assembly be back-to-back configuration mode both, also can combine aspectant configuration mode, and the matched bearing of two kinds of different configuration modes its preload and keep identical.Can also combine the configuration mode of series connection, after bearing both ends of the surface Internal and external cycle was concordant, preloading of bearing pack was the twice that single cover universal assembled angle contact ball bearing preloads.Do not influence the service behaviour and normal use of bearing pack after the assembly, assembling and use are all very convenient, and reliable performance, and long service life is applicable to machine tool chief axis, airplane engine main shaft or other high speed machines.
Description of drawings:
Fig. 1 is the structural representation of universal assembled angle contact ball bearing.
Among the figure: the 1-outer ring; The 2-inner ring; The 3-rolling element; The 4-retainer.
Specific embodiment:
