Background technique
In order to ensure good rotation smoothness, generally can by arranging the frictional force that bearing rotates with improved equipment between axle and axis hole;
Bearing is generally inside casing, housing and rotor structure, adopt static(al) to press-fit or expand with heat and contract with cold to manufacture, in order to ensure the rotation smoothness of bearing, need to control the degree of adaptability of roller and inside casing, housing, otherwise be easy to the stressed comparatively ambassador of axle, because the defect of bearing fit precision, make axle generation beat, affect the smooth and easy of transmission;
Particularly in the apparatus field that some are high-accuracy, quality of fit for bearing requires just higher, so the manufacture cost of bearing can rise by straight line, even if adopt high-accuracy bearing simultaneously, but high in some precision requirement, in the apparatus field that load-carrying is large, the roller of bearing extrudes the housing of bearing, inside casing very much, thus cause the housing of bearing, the quality of fit of inside casing changes, affect rotation coaxality and the precision of axle, badly influence normal production.
As
200820091082.5 disclosed inits bearing inside casing by eccentric setting of high-precision bearing for printing machine, housing and the self-stabilization mechanism between inside casing housing are to realize automatic calibration and the location of bearing, although this kind of bearing precision degree is higher, but in high load-bearing field, the damage that the self-stabilization mechanism of elastic material is easy to excessive deformation occurs and causes bearing, and when carrying too high, the feedback speed of autostability mechanism can reduce, and can badly influence the normal working performance of bearing.
Summary of the invention
The technical problem to be solved in the present invention is: overcome prior art middle (center) bearing and be subject to the excessive easy generation beat of bearing capacity and the problem of high-accuracy bearing mnanufacture high cost, provide a kind of anti-beat bearing of low cost.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of low beat bearing, comprise housing, inside casing and the roller be embedded between housing and inside casing, described roller comprises some rotary rollers and support rollers, the inside casing or housing of described bearing are provided with the annular groove for support rotating roller, a support ring is respectively provided with at the inside casing of described bearing or the both lateral sides of housing, described support ring comprises a supporting surface tilted to both sides towards bearing shaft, described support rollers is arranged between supporting surface and rotary roller, described support rollers is bar shaped or bulk, described rotary roller is spherical, top, the axial side pressure of described support rollers on the support surface, the axial opposite side top of described support rollers is pressed on rotary roller.
As further innovation of the present invention, described supporting surface is arc in the direction of the width.
As further innovation of the present invention, the side that support rollers contacts with rotary roller is arc or spherical.
As further innovation of the present invention, described support rollers adopts elastic alloy to make.
As further innovation of the present invention, described Elastic Steel is carbon spring steel.
As further innovation of the present invention, the axially middle part wall of described inside casing is processed with oil hole, and the axis of described oil hole and bearing tilts.
As further innovation of the present invention, the internal face of described housing and the outer wall of inside casing are provided with anodic oxidation hardened layer.
The invention has the beneficial effects as follows:
1, the supporting mechanism of the present invention by installing additional in traditional gear mechanism with support rollers, thus under lower machining accuracy, also the position degree that rotary roller is good can be ensured, when shaft strength, the movement even avoiding rotary roller can be reduced, to ensure the operating accuracy of bearing by the support of support rollers.
2, the surface of contact of arc can reduce skin friction, and the structure simultaneously arched upward can also improve support strength, prevents impacting the excessive supporting surface that allows and deforms.
3, the support rollers of elastic alloy material can improve the quality of fit of bearing by certain distortion, also can absorb the impact of bearing simultaneously.
4, oil hole carries out oiling in the middle part of bearing, dirty oil and foul can be pushed out from the both lateral sides of bearing easily, more be convenient to the maintenance of bearing.
5, anode hardened layer surface is dense, can reduce wearing and tearing and the distortion of bearing housing internal face that bearing impact causes and bearing inside casing outer wall.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Figure comprises: housing 1,
Inside casing 2,
Rotary roller 3,
Support rollers 4,
Supporting surface 1-1,
Annular groove 2-1,
Oil hole 2-2,
Support rollers and rotary roller contacting side 4-1.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1, the present invention is a kind of low beat bearing, comprise housing 1, inside casing 2 and the roller be embedded between housing 1 and inside casing 2, described roller comprises some rotary rollers 3 and support rollers 4, the inside casing 2 of described bearing is provided with the annular groove 2-1 for support rotating roller 3, a support ring is respectively provided with in the both lateral sides of described bearing housing 1 inwall, described support ring comprises a supporting surface 1-1 tilted to both sides towards bearing shaft, supporting surface 1-1 is arc in the direction of the width, described support rollers 4 is arranged between supporting surface 1-1 and rotary roller 3, described support rollers 4 is bar shaped or bulk, described rotary roller 3 is spherical, the top, axial side of described support rollers 4 is pressed on supporting surface 1-1, the axial opposite side top of described support rollers 4 is pressed on rotary roller 3, support rollers 4 and rotary roller 3 contacting side 4-1 are spherical.
