Abstract
The utility model provides a bearing axle clearance adjusts locking device, plays to bearing axle clearance adjustment, prevents the purpose become flexible. The device includes nut (1), nut two (5), retaining ring (3), locking pin (2), locking pin two (4). The bearing rotates the free clearance that should have the standard at the betweencenters, closes the angle soon through nut (1) and can confirm nut pretension volume to the free clearance of this adjusting block axial, the boss on retaining ring (3) blocks the recess that epaxial processing is good, and locking pin (2) compresses tightly retaining ring (3) through screw in retaining ring (3) lock nut (1), nut two (5), and two (4) screw in nuts two (5) and retaining ring (3) of locking pin prevent that nut two (5) from becoming flexible. Its parts machining is simple, is applicable to bearing axial precise adjustment's structure.
Description
Technical field
The utility model is related to bearing gap regulator, and more precisely, the utility model is related to bearing axial clearance
Adjustment locking device.
Background technology
Bearing axial clearance adjustment and locking mechanism generally existing in mechanical transmission structure.Traditional form mainly has: pressure
Lid is fixing, jump ring is fixed, double bolt is locked, the locking of round nut stop washer.
1st, gland fixed structure form is it is simply that pass through gland immediate constraint bearing axial displacement in the axial direction.The method is relatively
For universal.Advantage, easy accessibility, axial constraint power are big, are less prone to loosening: shortcoming, it is impossible to adjustment gap, fully relies on processing
Precision controlling dissociates gap, and error is big.
2nd, jump ring fixed structure form, it is simply that installing jump ring by machining clamp spring slot, fixes axial displacement.The method is multiplex
On the bearing position of compact conformation.Advantage, takes up room little: shortcoming, relies on machining control to dissociate gap it is impossible to adjust.Need
Specific purpose tool is installed, and axial constraint power is little.
3rd, double bolt lock compact forms are it is simply that axially utilize double tools for bolts ' pretensions, fixing bearing axial displacement.Advantage, structure letter
Single, convenient: shortcoming, affected can not accurately adjust gap by thread pitch.
4th, round nut stop washer form, is fixed by round nut pretension, the locked round nut of stop washer.Advantage, axially
Load is big, and adjustment gap effect is good: shortcoming, and round nut dismounting needs specific purpose tool inconvenient, needs percussion bending to stop during installation
Washer, can injuring part.
Above method is all described on mechanical design handbook, needs the device accurately adjusting bearing axial clearance to be but no situated between
Continue.Mainly adopt round nut stop washer form in industry, but the method be also dependence experience in implementation process it is impossible to
Accurately according to standard execution bearing free gap adjustment, and stop washer needs to tap bending with instrument, can injure part
And bearing.
For certain heavily loaded vehicle bridge, its hub bearing design space is narrow and small, axial load big, free gap needs accurately to adjust
Whole.Traditional bearing fixing structure is it is impossible to meet its design requirement.The utility model is related to a kind of bearing axial clearance adjustment lock
Tight device, reliable sexual satisfaction requires.
Special case: certain product adopts 4 points of angular contact bearings 36220, this type design axial direction equivalent load is 136kn, dissociates
Clearance criteria value is 0.116～0.176mm.General bearing fixed form all cannot meet the accuracy value adjustment of this bearing.Using
This structure, its Adjustment precision is up to 0.0208mm.After installing and using, bearing rotates freely.By verification experimental verification, high-speed rotation is not
Heating, heavily loaded non-loosening.This structural reliability meets requirement.
Utility model content
For the deficiencies in the prior art, the utility model proposes one kind is mainly by two nuts, locating snap ring, two tightening pins
The bearing axial clearance adjustment locking device combining, nut one can determine that nut pretension amount by screwing angle, to adjust
Bearing axially free gap, its axial end identical graduation circle is dispersed with four screwed holes, screwed hole center folder each other
Angle is different, uniform 18 through holes on locating snap ring, and this through hole and nut one, nut two head screwed hole have identical indexing
Circle, tightening pin one passes through locating snap ring to screw in nut one makes it lock, and nut two compresses locating snap ring, and tightening pin two screws in nut two
And penetrate locating snap ring and so that it is compressed.
Compared with the prior art, this structure has the advantage that
1st, fixing reliable to bearing, even if load change is big, be also not in loosening.
2nd, the precision of structure can change according to the bearing requirements selected, and range is wide.
3rd, split-type structure, does not need in assembling process to tap, easy to operate.
The 4th, the situation that tightening pin screwed hole cannot be aligned is considered from design principle, it is to avoid the nothing leading to because of foozle
Method is installed.
Brief description
Fig. 1 is the schematic perspective view of the utility model bearing gap regulator embodiment.
Fig. 2 is the version of nut in the utility model bearing gap regulator embodiment.
Fig. 3 is the version of stop washer in the utility model bearing gap regulator embodiment.
In figure, 1, nut 1, tightening pin 1, stop washer 4, tightening pin 25, nut two
Specific embodiment
Before the mounting, need first bearing axle head screw thread to be checked, remove screw thread process burr.Bearing be not installed
In the case of, pre- (examination) loading nut 1, it is ensured that screw thread bottom can smoothly be screwed, then screws out nut and formally installs.
As Fig. 1, bearing is installed on bearing position through axle head, raps bearing with wooden mallet it is ensured that bearing lower surface and crown of roll
Table top is sturdy.Nut 1 is screwed in from axle head, compresses bearing.Use hand rolling bearing, when rotating, bearing and spiral shell are described
Female patch closes consolidation.Load stop washer 3, the free gap then being needed according to standard adjustment, reversely screw out nut one during adjustment
1.(between through hole, angle is 20 °, and nut 1 has 4 screwed holes for such as Fig. 3, stop washer 3 totally 18 through holes, presss from both sides between screw thread
Angle is 25 °, 30 °, 35 ° respectively, as soon as long as so nut 1 rotates 5 °, having the through hole pair on a screwed hole and stop washer 3
Together, nut 1 and the screw thread that screws of axle are m72x1.5, so often rotating 5 °, nut 1 stroke is 0.0208mm.) adjust
Afterwards, screw in tightening pin 1, and sink to plane 2～3mm on stop washer 3.Reinstall nut 25 compression stop washer 3, rotation
Enter tightening pin 24, i.e. installation.
