Abstract

The utility model relates to a spring collar, in particular to a novel spring collar for a bearing. Specifically, the novel spring collar comprises a spring collar for a bearing hole and a spring collar for a bearing shaft; the spring collar for the bearing hole is contacted with a bearing outer ring; the spring collar for the bearing shaft is contacted with the bearing inner ring. The novel spring collar is characterized in that the upper end face of the spring collar for the bearing hole is a plane, and the lower end face of the spring collar for the bearing hole is an annular inclined plane; the upper end face of the spring collar for the bearing shaft is a plane, and the lower end face of the spring collar for the bearing shaft is an annular inclined plane. According to the novel spring collar for the bearing provided by the utility model, the position can be adjusted well, so that the bearing is well positioned in the axial direction, and axial endplay of the bearing shaft is prevented; compared with an original collar, the assembling time can be saved, and the assembling can be completed in place at one time; the novel spring collar is simple in structure and easy to process.

Description

A kind of novel bearing check ring

Technical field

The utility model relates to check ring field, and particularly a kind of bearing that makes is at axially locating Novel shaft check ring accurately.

Background technique

At present, in the axially locating of bearing, one side has shaft shoulder location, another side has check ring location, axially locating for bearing, because existing bearing is all plane (referring to Fig. 1-4) with back-up ring upper and lower surfaces, can be because producing axial clearance between foozle and the shaft shoulder and check ring when so bearing is fixed on axle, and this gap cannot be eliminated completely, can only reduce this gap by changing the check ring of different-thickness, waste time and energy, therefore provide a kind of novel bearing significant with check ring.

Model utility content

The utility model is intended to address the above problem, and a kind of novel bearing check ring is provided.

For achieving the above object, the technological scheme that the utility model adopts is as follows: a kind of novel bearing check ring, specifically comprise bearing internal circlip and bearing shaft check ring, described bearing internal circlip contacts with bearing outer ring, described bearing shaft contacts with bearing inner race with check ring, and the upper-end surface of described bearing internal circlip is plane, and lower end surface is annular slope, described bearing shaft is plane with the upper-end surface of check ring, and lower end surface is annular slope.

Further, described bearing internal circlip and described bearing shaft check ring are spring steel, and the material of described spring steel is 65Mn, 70 Si2Mn or 65Si2Mn.

Further, the annular slope of described bearing internal circlip lower end surface is identical with the amount of taper of the annular slope of check ring lower end surface with described bearing shaft.

Further, during assembling, the upper-end surface contact bearing inner ring of check ring for described bearing shaft, described bearing shaft spring catch

The lower end surface of circle deviates from bearing inner race.

Further, during assembling, the contact bearing outer ring, upper-end surface of described bearing internal circlip, described bearing hole spring catch

The lower end surface of circle deviates from bearing outer ring.

Further, the annular slope of described bearing internal circlip lower end surface and described bearing shaft are less than the friction angle between friction pair material with the amount of taper of the annular slope of check ring lower end surface.

Further, described bearing internal circlip and described bearing shaft check ring radially extendable.

A kind of novel bearing check ring that the utility model provides, can well adjust position, makes bearing axially well locating, and prevents bearing axial float; Than original back-up ring, can save installation time, can one-time-reach-place; Simple in structure, easily processing.

Specific embodiment

Below in conjunction with accompanying drawing, model utility is further described.

As shown in Fig. 5-8, bearing check ring of the present utility model, specifically comprise bearing internal circlip 1 and check ring 2 for bearing shaft, the upper-end surface of bearing internal circlip 1 is plane, lower end surface is annular slope, bearing shaft is plane with the upper-end surface of check ring 2, lower end surface is annular slope, bearing internal circlip 1 and described bearing shaft are spring steel with check ring 2, the material of spring steel is 65Mn, 70 Si2Mn or 65Si2Mn, the annular slope of bearing internal circlip 1 lower end surface is identical with the amount of taper of the annular slope of check ring 2 lower end surfaces with bearing shaft, during assembling, the upper-end surface contact bearing inner ring of check ring for bearing shaft, bearing shaft deviates from bearing inner race with the lower end surface of check ring, the contact bearing outer ring, upper-end surface of bearing internal circlip, the lower end surface of bearing internal circlip deviates from bearing outer ring, groove of difference car on shaft sleeve natural axis, the gradient on inclined-plane, groove outer end is consistent by the gradient of back-up ring with bearing, when gapped between bearing and bearing use check ring, bearing uses check ring due to self outside elastic force, back-up ring is stretched along radially outward, under the guiding on inclined-plane, to bearing side shifting, fill up gap vertically, guarantee the position of bearing, again because bearing is less than the friction angle between friction pair material and stops bearing outwards to move vertically with the angle of back-up ring inclined-plane and central axis, assurance bearing is reliably fixed position in axle sleeve and on axle, and then can accurately guarantee the position of bearing simultaneously.

Protection domain of the present utility model do not limit to ten this, be anyly familiar with those skilled in the art in the technical scope that the utility model discloses, the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
