Abstract
The invention relates to a bearing without windage, which includes an external ring, an internal ring and a rolling body which are arranged in an outer retainer. The key technical points are that the external ring is composed of two half external rings which are axially symmetrical to each other, the rolling body is arranged in a groove along the periphery of the internal ring by the connected half external rings and a corresponding elastic body; the elastic body, the external ring, the internal ring and the rolling body are assembled together by the external retainer. The invention is reasonable in design, easy to manufacture and can overcome the influence of the windage caused by the existing bearing; the invention not only can effectively eliminate the windage of the bearing but also has the automatic center regulation function and the self-centering function; the invention can reduce the vibration, decrease the noise and considerably improve the service life and the service performance of the bearing.
Description
Technical field
The present invention relates to a kind of rolling bearing, particularly a kind ofly can adjust the play of eliminating bearing automatically and have the self-aligning function and the clearance-free bearing of self-alignment function.It is applicable to places such as carrying low speed, underload and medium load.
Background technique
As everyone knows, traditional all kinds of rolling bearings except that split bearing, generally are made up of bulk metal inner ring and bulk metal outer ring and metal rolling element etc.Bearing is not when being installed on axle or bearing support, and a side of its inner ring or outer ring is fixing, makes loose another radially or axially keep certain adjustment amount then.According to adjusting the mode that moves, can be divided into radial internal clearance (GB/T 4604-2006) and axial internal clearance (axial internal clearance and radial internal clearance have certain functional relation).The play of bearing all has very big influence to the kinematic accuracy of the load distribution of bearing, vibration, noise, friction, working life and machinery etc.Particularly Bearing Installation is in the field of employment of low speed, underload and medium load etc., because the existence of bearing clearance, the radial and axial adjustment amount of movement of axle or bearing support is more obvious.
Summary of the invention
The purpose of this invention is to provide a kind of clearance-free bearing, its reasonable in design, easy to manufacture, can overcome the influence that there is play in existing bearing, not only eliminate the play of bearing effectively, but also possess self-aligning and self centering function, can reduce vibration, reduce noise, significantly improve bearing working life and usability.
The object of the present invention is achieved like this: this bearing comprises outer shroud, interior ring and the rolling element thereof that is assembled in the outer retainer, its technological points is: described outer shroud is made of half outer shroud of two axial symmetric arrangement, described rolling element encircles in the peripheral groove in being contained in by half involutory outer shroud and corresponding elastomer group, and with described outer retainer elastomer, outer shroud, interior ring and rolling element thereof is fitted together.
Described rolling element adopts spherical surface body or roller body.
Because outer shroud of the present invention is made of half outer shroud of two axial symmetric arrangement, in being contained in by half involutory outer shroud and corresponding elastomer group, rolling element encircles in the peripheral groove, and retainer fits together each part in addition, and is so it is reasonable in design, easy to manufacture.Pre-pressurized when being assembled in the retainer because of two bodies of this bearing remains with the corresponding site of rolling element two and half outer shrouds and contacts, so can reduce vibration, reduces noise, significantly improves bearing working life and usability.If use the elastomer of different hardness, can corresponding adjusting bearing radially reach axial displacement and aligning angle of oscillation, so just can overcome the influence that there is play in existing bearing, not only eliminate the play of bearing effectively, but also possess self-aligning and self centering function
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is a kind of concrete structure schematic representation of the present invention.
Fig. 2 is the I portion structure for amplifying schematic representation of Fig. 1.
Sequence number explanation among the figure: ring, 5 rolling elements in 1 outer retainer, 2 elastomers, 3 outer shrouds, 4.
Embodiment
Describe concrete structure of the present invention in detail according to Fig. 1 and mode of execution.This bearing adopts brand-new structural type, and it comprises the parts such as elastomer 2, outer shroud 3, interior ring 4 and rolling element 5 thereof that are assembled in the outer retainer 1.Wherein specification, model and the manufactured materials of outer shroud 3, interior ring 4 and rolling element 5 thereof should be determined according to the needs of actual usage requirement and design, and the internal diameter of the external diameter of outer retainer 1 and interior ring 4 should design according to the regulation of respective standard.The outer shroud 3 of present embodiment is made of half outer shroud of two axial symmetric arrangement.Rolling element 5 can adopt spherical surface body or roller body according to the concrete usage requirement of bearing.Rolling element 5 is assembled in the peripheral groove of interior ring 4 by outer shroud 3 and corresponding two elastomers 2 that left and right two half involutory outer shrouds constitute, and retainer 1 fits together elastomer 2, outer shroud 3, interior ring 4 and rolling element 5 thereof in addition.This retainer 1 can adopt assembling means or crimp technology commonly used, above-mentioned each part is coated fit together.In addition, regulate the purpose that bearing radially reaches axial displacement and adjusts the aligning angle of oscillation, can adopt the material that meets required hardness to make elastomer 2 for reaching, and pre-pressurized when making left and right two bodies be assembled in the retainer 1.
After this Bearing Installation, if because foozle causes the malalignment of bearing saddle bore or axle or produces when crooked, it can regulate coaxality automatically, so that improve kinematic accuracy, thereby improves bearing working life and usability.
Claims (2)
1, a kind of clearance-free bearing, comprise the outer shroud, interior ring and the rolling element that are assembled in the outer retainer, it is characterized in that: described outer shroud is made of half outer shroud of two axial symmetric arrangement, described rolling element encircles in the peripheral groove in being contained in by half involutory outer shroud and corresponding elastomer group, and with described outer retainer elastomer, outer shroud, interior ring and rolling element is fitted together.
2, clearance-free bearing according to claim 1 is characterized in that: described rolling element adopts spherical surface body or roller body.
