Description
Technical field
The utility model relates to a kind of ball bearing, relate in particular to a kind of can auto-compensation wearing clearance, effectively prevent premature failure, have the ball bearing than the long life.
Background technique
Ball bearing is a kind of as rolling bearing, is widely used in the every field of mechanical industry.The outstanding advantages such as that ball bearing in use has is easy to maintenance, reliability is high, startability is good.
Ball bearing generally comprises outer ring, inner ring, ball and retainer.Retainer between inner ring and outer ring with fixing and guiding ball.Because the inner ring of ball bearing is single structural type at present, consist of rotating mechanism with ball and outer ring, so the play of ball bearing is generally fixed value.Fixedly play can't carry out effective compensation to the wearing clearance that bearing produces at work.Along with the increase of operating time, the wearing clearance of ball bearing will increase gradually, finally cause the bearing premature failure, greatly shorten the working life of ball bearing.Simultaneously, because bearing can occur axially or circular runout at work usually, this will improve the Design and manufacture difficulty of high-precision bearing greatly, increase the Design and manufacture cost of bearing.
The model utility content
In view of the foregoing defects the prior art has, the utility model aim to provide a kind of with the combination inner ring, can auto-compensation wearing clearance, effectively prevent premature failure, have than long life, the difficulty that manufactures and designs and the relatively low ball bearing of cost.
To achieve these goals, the utility model by the following technical solutions: a kind of ball bearing comprises outer ring, retainer, ball and inner ring; Described ball bearing also comprises elastic positioning device, and described inner ring is the combination inner ring; The combination inner ring comprises interior annulus, outer toroid and the cushion that connects in turn vertically; Interior annulus and cylindrical endless belt gradient and gradient are all towards cushion; Be provided with ball in the space that forms between interior annulus, cushion and the outer toroid; Outer toroid and axle are for being slidingly matched; Elastic positioning device is positioned at the axial outside of combination inner ring and contacts with the combination inner ring.
In order to realize good compensation effect, the gradient of described interior annulus and outer toroid is preferably in 5 degree between 45 degree.
In order to realize good location and compensation effect, described elastic positioning device can be selected the combination of circlip, jump ring and resilient pad or the combination of nut and resilient pad.
For utilization efficiency and the life-span that increases ball bearing, can or radially take at the two ends of described ball bearing seal approach.
In order to bear larger load and to prevent the restrictive axes displacement, described ball bearing can be biserial.Ball, retainer, circlip and combination inner ring all can be two groups and arranged side by side vertically; Two groups of circlips lay respectively at the axial outside of two groups of combination inner rings and contact with two groups of combination inner rings.
Compared with the prior art, the utility model has been owing to adopted technique scheme, wearing clearance that can the auto-compensation ball bearing, effectively prevent the bearing premature failure, greatly prolong bearing working life, reduce difficulty and the cost of design bearing and manufacturing.

Embodiment
Below by embodiment the utility model is carried out concrete description; be necessary to be pointed out that at this following examples only are used for the utility model is further detailed; can not be interpreted as the restriction to the utility model protection domain, those skilled in the art can make some nonessential improvement and adjustment to the utility model according to foregoing.
Embodiment one: as shown in Figure 1, this ball bearing is single-row ball-bearing.This ball bearing comprises outer ring 1, ball 2, retainer 3, circlip 8 and combination inner ring 4.Combination inner ring 4 comprises interior annulus 5, outer toroid 6 and cushion 7.Interior annulus 5, cushion 7 are connected with outer toroid and are connected in turn along axle 9.Interior annulus 5 and outer toroid 6 band gradients and gradient are all towards cushion 7.Be provided with ball 2 in the space that forms between interior annulus 5, cushion 7 and the outer toroid 6.Outer toroid 6 and axle 9 are for being slidingly matched.Circlip 8 is positioned at the combination inner ring 4 axial outsides and contacts with combination inner ring 4.Circlip 8 cooperates the axially locating that realizes combination inner ring 4 and ball bearing with the shaft shoulder.When wearing and tearing appear in ball bearing at work, 8 pairs of circlips combination inner ring 4 will produce lateral thrust, make up between inner ring 4, ball 2 and the outer ring 1 and will form driving mechanism.Because outer toroid 6 and axle 9 are for being slidingly matched, under the effect of circlip 8 lateral thrusts, outer toroid 6 will produce along axle 9 and slide, and combination inner ring 4 is with the auto-compensation wearing clearance.Like this, bearing can continue to use in the situation that wearing and tearing occur.This will prolong the working life of ball bearing greatly.Simultaneously, because circlip 8 will apply suitable end thrust to ball bearing, can effectively reduce or avoid the radial and axial of ball bearing to beat, make and beat close to zero, thereby make the Design and manufacture of high-precision bearing simpler, reduced design difficulty, saved manufacture cost.
The gradient of interior annulus 5 and outer toroid 6 generally between 5 degree are spent to 45, has good transmission and compensation effect this moment.In order to realize better compensation effect, the matching gap between outer toroid 6 and the axle should be as far as possible little.
Circlip 8 is replaceable to be other elastic positioning devices, such as jump ring and resilient pad, or nut and resilient pad.
For the working life that prolongs ball bearing, the usability that improves ball bearing, Sealing 9 is equipped with at the two end part of ball bearing in the present embodiment.The position of Sealing 9 between outer toroid 6 and circlip 8, and by circlip 8 with its clamping.According to the sealing needs of different occasions, can adopt other end face seal mode or radial seals.
This bearing can adopt grease lubrication or oil lubrication, decides on concrete application.As using as the air spinning bearing, can adopt lubricated lipid, increase greasing hole and capping plug in addition in the outer ring.As substitute existing pressurized machine bearing at automobile booster, can adopt lubricated oils, drive hydraulic fluid port and oil outlet in the outer ring.
Embodiment two: as shown in Figure 2, this ball bearing is two-row ball bearing.With respect to single-row ball-bearing, two-row ball bearing can bear larger load, and can the restrictive axes displacement.This ball bearing comprises outer ring 10, ball 11, retainer 12, circlip 13 and combination inner ring 14.Ball 11, retainer 12, circlip 13 and combination inner ring 14 are two groups and arranged side by side vertically.Outer ring 10, ball 11, retainer 12 are identical with embodiment one with the arrangement mode of combination inner ring 14.Two groups of circlips lay respectively at the axial outside of two groups of combination inner rings and contact with two groups of combination inner rings.This ball bearing equally can the auto-compensation wearing clearance, and effectively reduces or avoid the radial and axial of ball bearing to beat.
