During the assembling process, with the apparatus, the processing manufacturing cost and assembling adjusting cost of the equipment can be substantially reduced and quantitative detection and on-line adjustment of the pre-tightening force of the angular contact bearing can be realized, thereby substantially improving consistency and reliability of the equipment assembling and prolonging the service life of the bearing. The detection apparatus with low cost can be operated simply and conveniently and is easy to realize.
Description
Technical field
The present invention is applied to plant equipment manufacturing, relating to a kind of on-line checkingi specifically, being adjusted to pick-up unit and detection method thereof to using angular contact bearing pretightning force.
Background technology
Bearing is the requisite corollary apparatus of plant equipment, and the nearly all gyration pair of plant equipment all will adopt bearing.Angular contact bearing is widely used in high-speed overload rotary pair, general paired use (back-to-back or face-to-face).Suitable pretightning force ensures that bearing runs well, the key of maintenance bearing ordinary life.Too low and the too high damage inefficacy that bearing all can be caused too early to the pretightning force of bearing applying, thus reduce the Acceptable life of bearing.Mostly is in the prior art by strictly controlling the dimensional tolerence of mechanism, ensures the decrement that preloading spring is suitable, thus realizes the object loading suitable pretightning force.Ensure the machining precision that part is strict, it is consistent and identical with the power required that pressure curve between tight spring individuality is given in guarantee, certainly will increase manufacturing cost; After Assembly of the parts, accumulated error differs simultaneously, causes assembling the value that the actual pretightning force of rear bearing cannot obtain requirement, and after assembling, actual pretension force value has no way of learning, causes bearing frequent breakage, and impact is normally produced.
Summary of the invention
Object of the present invention provides a kind of angular contact bearing pretightning force pick-up unit and detection method thereof for weak point existing in above-mentioned prior art just.
The object of the invention is to be achieved through the following technical solutions:
Angular contact bearing pretightning force pick-up unit of the present invention comprises force-measuring gauge support, the force-measuring gauge on force-measuring gauge support is arranged on by line slide rail, with the mode spinning of threaded engagement force-measuring gauge back-end support for drive force-measuring gauge linearly slide rail make the push rod of axial displacement campaign, and be arranged on the clamping sleeve of force-measuring gauge front end; The external diameter of described clamping sleeve is less than the internal diameter of corresponding bearing seat.
The detection method of angular contact bearing pretightning force of the present invention adopts following step to realize:
A, first by the left and right end of axle respectively by the Y-axis bearing on the end angular contact bearing installation frame of left and right, and in the cavity that right back-up ring group, enclosing springs are jointly formed with the blind end of right bearing seat outside right-hand member angular contact bearing, in the screw afterwards adjustment bolt spinning processed at the blind end of right bearing seat;
B, adjustment bolt is made to be in relaxed state;
C, spring, left back-up ring group are encapsulated in the outside of left end bearing, and pick-up unit is installed on left shaft holder outer face;
D, promote to compress interplanting axial displacement campaign, until contact with left back-up ring group by force-measuring gauge by the force-measuring gauge of rotating push rod drive installation on line slide rail;
E, adjustment force-measuring gauge are state at zero point;
F, adjustment rotating push rod and right-hand member adjustment bolt angular contact bearings apply pretightning force;
H, reading force-measuring gauge numerical value, until reach the pretightning force of angular contact bearing requirement;
I, clamping screw, remove pick-up unit;
J, left back-up ring group to be fixed.
Beneficial effect of the present invention is as follows:
Device of the present invention is by adjusting axial dimension, special gage is coordinated to locate, precision measuringtoll is utilized to read the force value of preloading spring acquisition, the pressure limit specified by making pretightning force reach bearing to the decrement adjustment of spring, described spring is separately positioned between two back-up rings of left and right back-up ring group.Device provided by the invention is adopted in assembling process, greatly can reduce the processing and manufacturing cost of equipment, equipment adjustment cost, realize the quantification detection of angular contact bearing pretightning force, on-line tuning, thus greatly improve consistance, the reliability of equipment assembling, improve the serviceable life of bearing.This installation cost is lower, and easy and simple to handle being easy to realizes.
