Description
Technical field
The present invention relates to a kind of methods of adjustment of tapered roller bearing end-play.
Background technique
Tapered roller bearing, which is mainly used in, belongs to divergence type bearing, and the inside and outside circle of bearing all has tapered raceway.It is single-row
Tapered roller bearing can bear radial load and single direction axial load.Tapered roller bearing is mainly used for bearing with radial direction
Radial direction and axial connected load based on load.Compared with angular contact ball bearing, tapered roller bearing large carrying capacity, the limit turns
Speed is low.Tapered roller bearing is able to bear the axial load in a direction, can limit the axial position in one direction of axis or shell
It moves.
Tapered roller bearing be mainly used for there are the reduction gearbox of axial load input high speed shaft both ends.It was run in equipment
Cheng Zhong, as axis temperature rises, is also easy to produce bearing inner race and takes roller expansion, to make if the clearance of high speed shaft upper bearing (metal) is too small
The problem of at bearing " killing ", equipment downtime；If the clearance of high speed shaft upper bearing (metal) is excessive, the raw vibratory impulse of fecund, and shadow
Ring the normal service life of bearing.The adjustment of clearance is completed before equipment factory in multiple row tapered roller bearing, install in equipment,
It is not required to be adjusted again in maintenance process.Single-row tapered roller bearing has two kinds of " face-to-face " ("<>") and " back-to-back " ("><")
Form.Wherein " back-to-back " installation form is difficult to adjust due to bearing clearance, and design is seldom using probability.General single-row circular cone rolling
Sub- bearing mostly uses the installation form of " face-to-face " in practice.During the installation process according to the property of divergence type bearing, it needs
Adjust the end-play of bearing.
There is the application of many single-row tapered roller bearings in the equipment of Ferrous Metallurgy production technology chain.As largest domestic
Ferrous Metallurgy service enterprise, everyday devices maintenance in frequently encounter tapered roller bearing dismounting, adjustment the case where.Very much
In speed reducer overhaul of the equipments project, bearing clearance adjustment is critical process.The construction speed of the process is the key that project process,
The construction quality of the process is even more the key of project construction quality.
Summary of the invention

First installation bolt is threadedly coupled with cabinet；In the step S7, the second installation is equipped on bearing gland in the second mounting hole
Bolt, the second installation bolt are threadedly coupled with cabinet.
Further, the bearing outer ring spacer includes adjustment spacer ring and bearing outside；The adjustment spacer ring is in circular ring shape；
The bearing outside includes prolonging along the first isolation part of tapered roller bearing radially extended and along the axial direction of tapered roller bearing
The second isolation part stretched；First isolation part and adjustment spacer ring be respectively positioned on tapered roller bearing outer ring and bearing gland it
Between；And the first isolation part of known bearing outside with a thickness of D；In the step S6, need first according to the thickness of bearing outer ring spacer
Degree X calculates the thickness X of adjustment spacer ring1；And adjust the thickness X of spacer ring1Calculation formula are as follows: X1=X-D；Further according to calculating
Adjustment spacer ring thickness X1, production adjustment spacer ring.
Further, in the step S4, end face and the circle of bearing measuring gland are measured at measured hole using micrometer
The end distance between the surface A of the outer ring of taper roller bearing.
Further, the method for adjustment of the tapered roller bearing end-play is further included step S8, is surveyed using dial gauge
Measure the clearance of tapered roller bearing.
Further, it in the step S2, needs that first tapered roller bearing is set on the intracorporal transmission shaft of case.
Further, in the step S3, apply a torque, if transmission shaft does not rotate, taper roller to transmission shaft
Roller is pressed on inner ring by the outer ring of bearing.
Further, lock shaft is made of jackscrew in the step S3.
Further, the thickness of the bearing measuring gland is equal with the thickness of bearing gland.
Further, the locking hole has multiple, and whole locking holes are uniformly distributed circumferentially；The measured hole have it is multiple,
Whole measured holes are uniformly distributed circumferentially.
