Description
Technical field
It is specifically a kind of to be filled for biserial thin-wall angular contact ball bearing the present invention relates to precise machine machining field
The device matched somebody with somebody.
Background technology
Biserial thin-wall angular contact ball bearing is a kind of military vehicle conveying shell bearing.Can bear it is larger using radial load as
Main footpath, axial two-way joint load and moment load, limit speed is higher, is mainly used for limiting axis or shell footpath, axial position
It moves.
The traditional assembling trap method of biserial thin-wall angular contact ball bearing is by the heated expansion of well-graded bearing outer ring
Afterwards rapidly with well-graded inner ring, keep that device assembly is mating fills out ball trap.The defects of conventional method, is to fill out spent by ball process
Time it is longer so that the outer ring after heating cools down rapidly, it is impossible to efficiently use bulk carry out trap, thereby result in raceway and steel
Ball surface is destroyed, and directly influences biserial thin-wall angular contact ball bearing finished product vibration values and feel quality so that strictly by technique
The bearing of standard processing, merely because the defects of assembly technique, causes the decline of product quality to a certain extent.
The optimal heat seal shape of biserial thin-wall angular contact ball bearing depends primarily upon three factors：1）Fore shaft size；2）Radially swim
Gap size；3）Bulk size and Quality degree of effective utilization after the heating of outer ring.Respectively it is more than twice of fore shaft size in radial internal clearance and bulk
When, it is heat seal optimum state, trap process is completed in the case where inner ring sub-assembly is advanced into certainly or is gently pressed into outer ring at this time,
Raceway and steel ball surface will not be caused to damage, it is ensured that the vibration values and feel of product reach standard requirement.But obtain this most
Good state, effective method can only be by quick heat seal.
Biserial thin-wall angular contact ball bearing includes two outer rings and an inner ring and steel ball and retainer, first during steel loading ball
First steel ball with grease is clung, is booked, then outer ring is heated, steel ball is packed into inner ring and outer ring.But meeting in assembling process
There is phenomena such as indivedual steel balls come off, interference volume does not reach requirement, cause to assemble unqualified, efficiency of assembling is low.
The content of the invention
For overcome the deficiencies in the prior art, goal of the invention of the invention is to provide a kind of biserial thin-wall angular contact ball bearing
Assemble device, to improve the assembly precision of biserial thin-wall angular contact ball bearing, qualification rate and efficiency, and then improve equipment precision and
Service life.
To achieve the above object, the present invention includes being used to implement the assembling device one of biserial thin-wall angular contact ball bearing assembling
And assembling device two；
Circumferentially there are several holes on the step pedestal one of the assembling device one, spring one, bearing are housed in hole
Inner ring is positioned on the step one of step pedestal one by step one；The bottom surface of upper positioning seat one is supported on spring one, upper fixed
The position inner circle of seat one is bonded with the outer circle of inner ring, and upper positioning seat one carries straight step and type conical bench, type conical bench and straight step
Faying face it is consistent with the centre-height of the raceway one of the steel loading ball one of inner ring；Steel ball one is booked to the raceway one and taper of inner ring
Between step, the straight step of the outer ring one after heating along upper positioning seat one is buckled into and is pressed downward, be packed into outer ring one, make outer ring one
Bottom surface is consistent with the centre-height of the raceway one of inner ring, by outer ring one and steel ball one, inner ring trap；
Circumferentially several holes on the step pedestal two of the assembling device two are equipped with spring two, transition disc in hole
Bottom surface be supported on spring two, transition side surface carries four pin holes, will be after above-mentioned outer ring one and steel ball one, inner ring trap
Partial switching is fixed between the step two of step pedestal two and transition disc, and inner ring is placed at the step two of step pedestal two, outside
Circle one is placed at the step three in transition disc；It is connected between transition disc and upper positioning seat two with pin, upper positioning seat two carries platform
Rank four, the bottom surface of step four are consistent with the centre-height of the raceway two of the steel loading ball two of inner ring；Steel ball two is booked to the rolling of inner ring
Between road two and upper positioning seat two, the outer ring after heating two is made to be buckled into along the step four in transition disc and is pressed downward, outer ring two and steel
Ball two, inner ring trap, pin is transferred to, separately upper positioning seat two, completes a whole set of bearing assembling.
The upper positioning seat two is made of separable two parts, including positioning seat two on positioning seat two, second on first.
Compared with prior art, the present invention after assembling device using biserial thin-wall angular contact ball bearing, convenient, fast can fill
With bearing, operating time and production efficiency are effectively improved；It can ensure that the vibration values of product and feel reach standard requirement, improve production
Quality and qualification rate, reduction is done over again and waste product.
