At side.Wherein, the size of loading force is conducted oneself with dignity according to bearing and is determined, takes 30%~50% that bearing is conducted oneself with dignity.
(3) clearance between third row roller 3 and the 4th row roller 4 is measured
The first step, adjustment process：Continue adjust adjustment threaded rod 15 moved up relative to the position of pilot sleeve 16, move up away from
It is determined according to the boss thickness of measured bearing size and upper holder block 17 from size, it is slightly lower to adjust threaded rod disk end face 15-1 at this time
In the upper surface of upper end inner ring 5, while adjusting threaded rod screw thread end face 15-2 and being disengaged with lower lock block 14.
Second step, clamping：Upper holder block 17 declines in the case where load cylinder drives, and contacts and compress the disk of adjustment threaded rod 15
Lower end inner ring 7 is pressed on lower lock block 14 by end face 15-1 by pilot sleeve 16, cone spacer 6, and upper end inner ring 5 is axial at this time
Freely；After clamping lower end inner ring 7, outside the contact to upper end list raceway of adjusting displacement sensor a19 and displacement sensor b20
The upper surface of circle 8.
Third step, loading effect：After clamping lower end inner ring 7, upper loaded ring 18 load cylinder drive lower axle to decline
To the upper surface of contact upper end list raceway outer ring 8, and to its downward on-load pressure, pass through drive for upper end list raceway outer ring 8
Upper end outer ring spacer 9 and outer ring with double raceway 10 decline, and the big end of compression third row roller 3 is adjacent to keeps off greatly in the upside of lower end inner ring 7
At side；Unload upper end and load cylinder, upper loaded ring 18 retracts, lower loaded ring 13 under the action of lower end loads cylinder axially upwards
It is moved to the lower face of contact lower end list raceway outer ring 12, and to its upward on-load pressure, is pressed for lower end list raceway outer ring 12
The big end of tight 4th row roller 4 is adjacent at the downside large-flange of lower end inner ring 7.Wherein, the size of loading force according to bearing from
It determines again, takes 30%~50% that bearing is conducted oneself with dignity；After measurement, lower end loading force is unloaded, lower loaded ring 13 is retracted.
The utility model advantageous effect is：Position by adjusting screw thread guide rod relative to pilot sleeve is realized to not
With the clamping of inner ring, the load to different lines roller is realized by loading device, by the axial play of former four-row tapered roller bearing
Gap measures the end-play that ingenious equivalent conversion is three groups of double-row conical bearings and measures, measurement method is simple, it is easy to operate, keep away
Without overturning when having exempted from roller self-locking, having measured, it can be realized by automation equipment, greatly improve measurement efficiency and measurement accuracy.
