Abstract
The invention relates to a bearing centering device, which comprises a centering shaft and is characterized in that: the centering sleeve is also included; the centering shaft comprises a first shoulder; a bearing and a spring retainer ring are arranged in the centering sleeve; the spring retainer ring is clamped in the groove of the centering sleeve and used for inhibiting the axial movement of the bearing; the centering sleeve is arranged on a first shaft shoulder of the centering shaft through a bearing; the centering sleeve is in interference fit with the bearing, and the inner diameter of the centering sleeve is larger than the outer diameter of the bearing. The bearing centering device of the scheme of the invention improves the dimensional accuracy of the inner diameter of the bearing, the form and position tolerances such as roundness, cylindricity and the like, reduces the rejection rate of products, improves the appearance quality of the products, reduces the cost and has good use effect.
Description
Technical field
The present invention relates to a kind of centring means, relate in particular to a kind of bearing centring means that is used in the processing of bearing inner race raceway groove, belong to mechanical spare and accessory parts technical field.
Background technology
In the microstoning of bearing inner race raceway groove, be by the hydraulic system fuel feeding, make between fixed centring means and the bearing inner race internal diameter and produce oil film; Bearing inner race is under the drive of main shaft; Do rotation at a high speed, under ultra essential oil stone oscillating grinding, reach bearing inner race raceway groove superlinishing purpose.But in process, because certain off-centre appears between the two in the gap instability between the internal diameter of the centering copper sheathing external diameter that the vibration of main shaft causes fixed centring means and converted products; And this device does not have the automatic aligning function; Cause converted products in the high speed rotary course, produce friction with the centering copper sheathing and wear and tear, the percent defective of converted products is increased; The presentation quality of bearing inner race is relatively poor, causes waste.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind ofly can improve machining accuracy, the bearing centring means of the rate of reducing the number of rejects and seconds.
Technical solution of the present invention is achieved in that a kind of bearing centring means, comprises centration axis, it is characterized in that: also comprise centring sleeve; Said centration axis comprises first shaft shoulder; Bearing, check ring are housed in the said centring sleeve; Said check ring is stuck in the groove of centring sleeve, in order to suppress the axial float of bearing; Said centring sleeve is arranged on first shaft shoulder of centration axis through bearing.
Preferably, said centring sleeve and bearing are interference fit, and the centring sleeve internal diameter is greater than the external diameter of bearing.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The present invention program's bearing centring means has improved form and position tolerances such as internal diameter of bearing precision and circularity, cylindricity, has reduced the percent defective of product, has improved the product appearance quality, reduces cost, and has good result of use.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the three-dimensional structure diagram of a kind of bearing centring means of the present invention;
Accompanying drawing 2 is the cutaway view of a kind of bearing centring means of the present invention;
Wherein: 1, centration axis; 2, centring sleeve; 3, bearing; 4, check ring; 5, first shaft shoulder; 6, groove.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further detailed description.
Accompanying drawing 1,2 is a kind of bearing centring means of the present invention, comprises centration axis 1, centring sleeve 2; Said centration axis 1 comprises first shaft shoulder 5; Bearing 3, check ring 4 are housed in the said centring sleeve 2; Said check ring 4 is stuck in 6 li of the grooves of centring sleeve 2, in order to suppress the axial float of bearing 3; Said centring sleeve 2 is arranged on first shaft shoulder 5 of centration axis 1 through bearing 3; Said centring sleeve 2 is an interference fit with bearing 3, can realize bearing radial force and spinfunction.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The present invention program's bearing centring means has improved form and position tolerances such as internal diameter of bearing precision and circularity, cylindricity, has reduced the percent defective of product, has improved the product appearance quality, reduces cost, and has good result of use.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
