Abstract

The utility model relates to a radial force mute rolling and sliding bearing, which represents a new generation of bearings to replace sliding bearings and rolling bearings, comprising an outer ferrule, an inner ferrule and a rolling and sliding ring, wherein both the inner ferrule and the outer ferrule comprise two symmetrical rings with an L-shaped axial section, respectively fastened together by a fastening ring and a tension ring; the rolling and sliding ring is positioned between the inner ferrule and the outer ferrule. The utility model has the advantages of that: the strong shockproof capability and rigidity of sliding bearings are combined with the strong dynamic flexibility of rolling bearings. Being innovatively structured without noise pollution, the utility model is a new type of radial force mute rolling and sliding bearing that integrates economical efficiency and practicability.

Description

The quiet skid dynamic bearing of radial force

Technical field

The quiet skid dynamic bearing of radial force described in the utility model is the bearing of new generation of a kind of alternative sliding bearing and rolling bearing.

Background technique

Our employed bearing, the sliding bearing of the first generation and rolling bearing of the second generation at present.The sliding bearing of the first generation is a single watt of cover endoporus chute surface and axle thick stick chute surface relative coupling, and fixing watt is overlapped a stress diverter surface and wear and tear easily.Because axle thick stick and bearing shell are independent play, the oil-film damping friction is big relatively, and consumes energy is many.And exist easily and pull, wrap watt, dynamic flexible difference or the like technical problem.Though and the rolling bearing of the second generation is better than first generation sliding bearing.But also exist owing to be the contact of point, uniaxial stress, wherein Gu Ding lasso raceway stress plane switching point weares and teares easily, or locally chaps, peels off iron filings and stop working life.And the ability that exists a bearing load is weak, impact resistant rigid is lower.The return motion because the inner amboceptor rolling of bearing bearing pearl should not be brought to a halt, when intense impact, the coupling part is broken easily or the like.At existing problem in the prior art, a kind of novel bearing of research and design, existing problem is very necessary in the prior art thereby overcome.

Goal of the invention

In view of existing problem in the prior art, the purpose of this utility model is a kind of skid dynamic bearing of research and design, be that the advantage of first generation tradition sliding tile bearing and second generation conventional rolling bearing structure support technology is combined, become the reorganization design of support structure technology by " H ∞ sliding mode control theory ", the shock-resistant rigidity of first generation tradition sliding bearing dynamic flexible strong and second generation conventional rolling bearing is combined, thus the bearing of design " skid is moving " dual functions.The quiet skid dynamic bearing of radial force described in the utility model, its structure is made up of inside race, outer collar, skid rotating ring.Inside race is the annulus that is two " L " letter shapes by identical, the axial section of boundary dimension, the face-to-face relatively left inside race and the right inside race of coupling, and tighten together by the straight tubular fastening ring of annulus, be combined into a complete inside race; Outer collar also is the annulus that is two " L " letter shapes by identical, the axial section of boundary dimension, the face-to-face relatively left outer collar and the right outer collar of coupling, and tighten together by the straight tubular tensioner of annulus circle, be combined into a complete outer collar; The skid rotating ring is a straight tubular circle, is " worker " word shape, and its endoporus rolls chute surface and rolls with the cylindrical of fastening ring that chute surface is relative to be mated, and its cylindrical rolls chute surface and rolls with the interior circle of tensioner circle that chute surface is relative to be mated.The quiet skid dynamic bearing of radial force described in the utility model, the endoporus of the cylindrical of its fastening ring and tensioner circle is the play chute surface, is provided with the orderly radial hole of several symmetric arrays on the play chute surface.The quiet skid dynamic bearing of radial force described in the utility model, respectively there is a place " recessed " font peripheral groove at end face center, the axial both sides of its skid rotating ring, at channel bottom evenly distributed several axial pass-through holes of order is arranged.The quiet skid dynamic bearing of radial force described in the utility model, the inside and outside of its skid rotating ring rolled on the chute surface, evenly distributed two conducts of order arranged to tapered openings, and is connected perforation with axial pass-through holes.The radial taper aperture that the quiet skid dynamic bearing of radial force described in the utility model, the endoporus of its skid rotating ring and cylindrical roll the sliding channel face all is provided with " V " font structure convergence oil groove line.The utility model provides a kind of novel radial force quiet skid dynamic bearing.Because the setting of skid rotating ring, it is strong to make the utility model not only have the impact resistance of sliding bearing, but also has possessed the advantage of the rolling flexibility of rolling bearing.Because the setting of the axial pass-through holes of skid rotating ring and radial taper aperture and " V " font structure convergence line of rabbet joint makes the lubricated heat radiation of bearing good.The combined type fit of inside race and outer collar is more convenient for the loading and unloading and the maintenance of bearing.Because the utility model has possessed the advantage of rolling bearing and sliding bearing simultaneously, so the utility model needs applicable to various different operatings place and environment bearing.Advantage, its large batch of putting goods on the market such as the utlity model has novel structure, noise-less pollution, be convenient to assembly and disassembly maintenance, be widely applicable will produce positive social benefit and remarkable economic efficiency.

Description of drawings

The utility model has an accompanying drawing

Among the figure: 1, left inside race 2, right inside race 3, fastening ring 4, right outer collar 5, outer collar 6, tensioner circle 7, skid rotating ring 8, axial pass-through holes 9, " V " font structure convergence oil groove line 10, radial taper aperture

Embodiment

Specific embodiment of the utility model as shown in drawings, two separable symmetrical lassos, promptly left inside race 1 and right inside race 2 tighten up the cylindrical of two inside races with a straight tubular fastening ring 3 of annulus and to snap together, and present a complete inside race.By two separable symmetrical lassos, promptly right outer collar 4 and left outer collar 5 with the straight tubular tensioner of an annulus circle 6 the endoporus tensioner of two outer collar together, present a complete outer collar.Endosome supporter in the middle of outer collar and the inside race promptly is a skid rotating ring 7.7 designs of skid rotating ring have axial pass-through holes 8 and radial taper aperture 10.Be provided with " V " font structure convergence oil groove line 9 simultaneously.Can store lubricant oil in the radial taper aperture 10, axial pass-through holes 8 promptly plays lubrication and also plays thermolysis.The effect of " V " font structure convergence oil groove line is that lubricant oil is converged wedge-shaped oil film, and skid road matrix stress diverter surface is reduced friction, and prolongs the operating life of matching materials.The utility model adopts split modular structure, and installing/dismounting, maintenance are more apparent convenient and swift.
