Description
Technical field
The utility model belongs to the detection technique field of rolling bearing, relates generally to a kind of cylinder roller bearing inner ring assembly
The detection device of middle roller deflection.
Background technology
Cylinder roller bearing has the characteristics that radial direction bearing capacity is high and radial rigidity is high and is widely used in machine tool chief axis, rolls
The mechanized equipments such as machine, rolling stock and lifting equipment.Under normal circumstances, retainer is transported according to the cylinder roller bearing of design
Turn the difference of guidance mode, the cylinder roller bearing structure formed also differs；If usual inner ring guiding retainer operating
When, then retainer can form inner ring assembly with inner ring, cylindrical roller, if during outer ring guiding retainer operating, then retainer meeting
Outer ring assembl is formed with outer ring, cylindrical roller.
Usually, the inner ring assembly of cylinder roller bearing is by the inner ring with double ribs, the retainer with outer lock claw
And cylindrical roller is after assembling, then by carrying out bending claws process to the retainer with outer lock claw（I.e. external lock claw is pressed
It is curved）So that three forms inseparable assembly；After inner ring assembly is formed, cylindrical roller is enclosed in by inner ring raceway, gear
In the ring of encirclement that side and retainer pocket hole and outer lock claw are formed so that cylindrical roller is only in inner ring assembly retainer pocket hole
Radially there is the spacious amount of certain movement, and the cylindrical roller both ends of the surface of only fraction are exposed outside, so that testing staff uses
Finger grip roller limited space.It is general require cylindrical roller have in radial direction retainer pocket hole 1.3 ± 0.5mm ~ 2.5 ±
The deflection S of 0.5mm, is that cylindrical roller is moved into contact with bending claws in retainer pocket hole from contact inner ring raceway position one end
Position one end moves radially spacious amount.The size of roller deflection is decided by bending claws process quality, further affects bearing
Quality and performance are assembled, therefore, roller deflection is that the inner ring assembly of cylinder roller bearing is indispensable in assembling
Inspection project.
In inner ring assembly, since roller is in inner ring raceway, rib and retainer pocket hole and outer lock claw formed
In the ring of encirclement, roller can not be fixed when contacting this extreme position of retainer bending claws, and grip roller both ends of the surface
Limited space so that there are certain difficulty for the accurate detection of deflection.
At present, mainly still it is detected in existing detection method using slide calliper rule, under normal circumstances, testing staff first uses
Slide calliper rule measure size of the roller when contacting raceway position, then estimate size during roller contact retainer bending claws position,
Finally it will draw roller deflection by subtracting each other by gained measured value twice.Testing staff is solution roller contact retainer bending claws position
The problem of Shi Wufa is fixed, a usual testing staff is measured with hand grip roller, another testing staff with slide calliper rule；Or
One testing staff of person is aerial vertically by inner ring assembly on the other hand, it is naturally drooped contact retainer using the dead weight of roller curved
Pawl, on the other hand by the movable end of slide calliper rule gently contact roller, estimates the indicating value for reading slide calliper rule.Although detect this method using slide calliper rule to grasp
Make simple and practicable, but personnel's operating error is bigger and uncontrollable, and measurement result is inaccurate, and then influences to cylinder roller bearing
Judgement whether assembling up-to-standard.

The lower end for the support shaft that the bearing support stated coordinates is fixed on platform, form the inner ring assembly, mandrel can be relative to branch
Support the rotating structure of axis；The column parallel with support shaft is further fixed on the platform；Clamping is installed on the column
Dial framework to the measurement table measured to the cylindrical roller deflection of inner ring assembly；The detection device further includes useful
To clamp the clip attachment of cylindrical roller；The clip attachment has clip, and the openend of the clip is equipped with clip skin
Set；The openend of the clip is clamped in the both ends of cylindrical roller described in inner ring assembly.
The utility model proposes a kind of cylinder roller bearing in inner ring assembly roller deflection detection device, in use
Technical solution is stated, is had the advantages that：
1）Detection device described in the utility model can directly and accurately measure cylindrical roller is every in inner ring assembly
Deflection in a retainer pocket hole.
2）Detection device overall structure described in the utility model is simple, easy to implement and easy to operate；By configuring phase
The mandrel answered, the then detection that can solve roller deflection in the cylinder roller bearing inner ring assembly of various models and specification are difficult
Topic.
3）Detection device described in the utility model can reduce the manual inaccuracy of testing staff and
The uncomfortable property of manual grip squeegee operations, and certain testing cost and labour can be reduced.
