Description
Technical field
The utility model relates to a kind of pick-up unit of axial clearance of double-row conical bearing, belongs 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 lift inner ring with all the other fingers 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, to be contained in a support that can overturn for the mandrel that measured bearing is installed, measured bearing is arranged on mandrel and pushes down inner ring end face the locking of bearing by gland, load to the inner ring of measured bearing, 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 in the time of 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 in the time 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 purpose of this utility model is to provide a kind of 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 utility model 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.
