Description
Technical field
The present invention relates to a kind of pick-up unit of axial clearance of double-row conical bearing, belong to double-row conical bearing detection technique field.
Background technology
Double-row conical bearing application scenario requires higher to its load-bearing capacity and serviceable life, and axial clearance of double-row conical bearing is to bearing rotation precision, the impact such as load-bearing capacity and serviceable life is comparatively large, therefore, controls axial clearance of double-row conical bearing very important.
Two kinds are had at present to the method for double-row conical bearing measurement end-play, one adopts hand dipping, first operating personnel pin the cycle surface of bearing with thumb, and then lift inner ring determine with feeling with all the other fingers, namely operating personnel are to fixing load and the mobile inner ring of directly adding in the outer ring of measured bearing, then the displacement of inner ring is felt, but because testing staff's gimmick is different, feel different caused by, therefore manual detection error is too large, not only inefficiency, and the end-play detected is inaccurate.Another kind of mode adopts special detecting instrument, that the mandrel for installing measured bearing is contained in a support that can overturn, measured bearing to be arranged on mandrel and to push down the inner ring end face of bearing by gland and lock, namely the inner ring to measured bearing loads, rotate the outer ring of measured bearing, by the measured value of the rack-mount end face in centimeter check measured bearing outer ring, after again support being overturn 180 °, detect the measured value of another end face of measured bearing outer ring again, the average measurement value at two ends is the end-play of double-row conical bearing.But when the cycle surface of centimeter check measured bearing, its outer ring there will be dancing in rotation process, can draw multiple measured value, so accurately cannot draw measured value, not only affects detection efficiency, and affects the accuracy of its end-play.Secondly above-mentioned two kinds of modes are when detecting, all need to load the inner ring of measured bearing, detect the outer ring that it rotates again, the measured bearing after loading there will be the locking phenomenon of roller, and the play value amount that equally also can cause the double-row conical bearing measured is inaccurate.
Summary of the invention
The object of this invention is to provide a kind of structure simple, easy to operate, can detection efficiency be improved, the pick-up unit of the axial clearance of double-row conical bearing of detection accuracy can be improved again.
The present invention is the technical scheme achieved the above object: a kind of pick-up unit of axial clearance of double-row conical bearing, comprise and be arranged on gauge stand rotatable L shape bearing and meter, it is characterized in that: described L shape bearing comprises base plate and riser, base plate is provided with the U-lag passed through for mandrel, holder is arranged on base plate, it is corresponding with the notch of U-lag on base plate that holder is provided with the opening passed through for measured bearing, the back-up ring stretched in holder is provided with, the outer ring of measured bearing is arranged in holder, one end of the outer ring of measured bearing connects with base plate, the other end connects with the back-up ring on holder and axial limiting, mandrel in step is arranged on base plate by measured bearing, described mandrel comprise match with the inner ring of measured bearing intermediate shaft, be positioned at intermediate shaft side and diameter is greater than the shaft shoulder of intermediate shaft and is positioned at intermediate shaft opposite side and diameter is less than the thread spindle of intermediate shaft, clamp ring is screwed on the thread spindle of mandrel, and the shaft shoulder on mandrel connects with inner ring one end of measured bearing and axial limiting, dial framework is arranged on the riser of L shape bearing, and meter is arranged on dial framework, and the test side of meter connects with the end face of mandrel, and central axis and the load-bearing of mandrel rotation center axis of described test side are closed.
Measured bearing conveniently can be arranged on mandrel or from mandrel by mandrel and clamp ring and remove by the present invention, by the intermediate shaft on mandrel, radial location is carried out to the inner ring of measured bearing, the measured bearing be arranged on mandrel is passed the U-lag on L shape bearing and the opening on holder, when measured bearing being placed on L shape bearing, by the base plate on the back-up ring on holder and L shape bearing, axial limiting is carried out to the two ends of measured bearing outer ring, and limit outer ring action, conveniently undertaken spacing by measured bearing, operation is very easy.The measuring position of meter of the present invention is at end face of mandrel, when measured bearing is arranged on after between holder and base plate, measured bearing is fixed on L shape bearing, between holder and mandrel, because axial location is carried out by the shaft shoulder on mandrel in one end of the inner ring of measured bearing, the other end is free state, for no-load is measured, test side central axis and the load-bearing of mandrel rotation center axis of meter are closed, when rotating outer ring, only can obtain a measured value of measured bearing inner ring, solve the phenomenon of the multiple measured values occurred because outer ring swings in measuring process, improve measuring accuracy.The present invention is when rotation lock collar drives measured bearing inner ring to rotate by mandrel, due to inner ring one end of measured bearing connect with the shaft shoulder of mandrel, the other end is free shape, the displacement of the inner ring of measured bearing when measuring end face of mandrel respectively on top and bottom by meter, and obtain measured bearing average end-play value accurately.
The test side of meter of the present invention does not contact with the outer ring of measured bearing or inner ring, only with the end contact of mandrel, also without the need to loading the inner ring of measured bearing or outer ring, that no-load is measured, the locking phenomenon that the roller that not only avoid measured bearing occurs, temperature of inner ring during rotation while spacing to outer ring, the duty of measured bearing can be simulated, by the displacement of inner ring during measurement no-load, play value accurately can be obtained, therefore measuring accuracy is high.The present invention is convenient to be arranged on measured bearing on mandrel, and is also conveniently arranged on L shape bearing and holder by the assembly installed, and have good operability, labour intensity is little, measures efficiency high.The present invention is provided with locating part on the back-up ring of holder, axial limiting can be carried out to the other end of measured bearing outer ring by locating part, therefore the convenient distance regulating axial limiting, can be applicable to the detection of the double-row conical bearing of different model, adjust easy to use.
