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, load-bearing capacity and serviceable life etc., impact was larger, therefore, controlled axial clearance of double-row conical bearing very important.
At present the method for double-row conical bearing measurement end-play is had to two kinds, one is to adopt hand dipping, first operating personnel pin the cycle surface of bearing with thumb, and then with all the other fingers, lift inner ring and determine with sensation, be that operating personnel directly add load and mobile inner ring to the outer ring of measured bearing is fixing, then feel the displacement of inner ring, but because of testing staff's gimmick difference, feel different due to, therefore manual detection error is too large, not only inefficiency, and the end-play detecting is inaccurate.Another kind of mode adopts special detecting instrument, for the mandrel that measured bearing is installed, to be contained in a support that can overturn, measured bearing is arranged on mandrel and by gland, pushes down inner ring end face the locking of bearing, to the inner ring of measured bearing, load, the outer ring of rotation measured bearing, by the measured value of the rack-mount end face in centimeter check measured bearing outer ring, again by after 180 ° of support upsets, detect again the measured value of another end face of measured bearing outer ring, the end-play that the average measurement value at two ends is 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 values, so cannot accurately 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 the inner ring of measured bearing to load, detect the outer ring of its rotation, the measured bearing after loading there will be the locking phenomenon of roller again, and it is inaccurate equally also can causing the play value amount of the double-row conical bearing of measuring.
Summary of the invention
The object of this invention is to provide one simple in structure, easy to operate, can improve detection efficiency, can improve again the pick-up unit of the axial clearance of double-row conical bearing of detection accuracy.
The present invention is that the technical scheme achieving the above object is: a kind of pick-up unit of axial clearance of double-row conical bearing, comprise and be arranged on the rotatable L shaped bearing of gauge stand and meter, it is characterized in that: described L shaped bearing comprises base plate and riser, base plate is provided with the U-lag passing 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 passing through for measured bearing, the back-up ring of stretching in holder is provided with, the outer ring of measured bearing is arranged in holder, one end and the base plate of the outer ring of measured bearing join, back-up ring on the other end and holder joins and axial limiting, the mandrel that is step is arranged on base plate by measured bearing, described mandrel comprises the intermediate shaft that matches with the inner ring of measured bearing, be positioned at intermediate shaft one 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 inner ring one end of the shaft shoulder on mandrel and measured bearing joins and axial limiting, dial framework is arranged on the riser of L shaped bearing, and meter is arranged on dial framework, and the test side of meter and the end face of mandrel join, and the central axis of described test side and the load-bearing of mandrel rotation center axis are closed.
The present invention can be conveniently arranged on measured bearing on mandrel or from mandrel and remove by mandrel and clamp ring, by the intermediate shaft on mandrel, the inner ring of measured bearing is carried out to radial location, to be arranged on measured bearing on mandrel through the U-lag on L shaped bearing and the opening on holder, when measured bearing is placed on L shaped bearing, by the base plate on the back-up ring on holder and L shaped bearing, axial limiting is carried out in the two ends of measured bearing outer ring, and the action of restriction outer ring, convenience is carried out measured bearing spacing, and operation is very easy.The measuring position of meter of the present invention is at end face of mandrel, after measured bearing is arranged between holder and base plate, measured bearing is fixed on to L shaped 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, the test side central axis of meter and the load-bearing of mandrel rotation center axis are closed, when rotating outer ring, only can obtain a measured value of measured bearing inner ring, solved the phenomenon that swings the multiple measured values that occur in measuring process due to outer ring, improved 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 and the shaft shoulder of mandrel joins, the other end is free shape, the displacement of the inner ring of measured bearing when measuring respectively end face of mandrel in 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 outer ring or the inner ring of measured bearing, only with the end contact of mandrel, also without the inner ring to measured bearing or outer ring, load, that no-load is measured, the locking phenomenon of not only having avoided the roller of measured bearing to occur, temperature of inner ring during rotation in spacing to outer ring, can simulate the duty of measured bearing, during by measurement no-load, the displacement of inner ring, can obtain play value accurately, therefore measuring accuracy is high.The present invention is convenient to be arranged on measured bearing on mandrel, and also facilitates the assembly installing is arranged on L shaped bearing and holder, has good operability, and labour intensity is little, measures efficiency high.The present invention is provided with locating part on the back-up ring of holder, by locating part, can carry out axial limiting to the other end of measured bearing outer ring, therefore the convenient distance that regulates axial limiting, can be applicable to the detection of the double-row conical bearing of different model, adjusts easy to use.
