Measuring device for axial play of double row conical bearing with inner and outer ring spacer

A measuring device for an axial play of a double row conical bearing with an inner ring spacer and an outer ring spacer belongs to the technical field of mechanical part measurement. The utility model is composed of a dial indicator, fastening screws, a rod seat of the dial indicator, a drop height measuring rod, a seat of the drop height measuring rod, nuts, a drop height cushion, a drop height spacing ring, a spring cushion, bolts and horizontal proof table block. Firstly, the axial distance t1 between the non-base end face of an inner ring and the base end of an outer ring of a set of a single row conical bearing is measured, secondly, the axial distance t2 of both end faces of an inner ring spacer and an outer ring spacer of a set of a single row conical bearing with the inner ring spacer and the outer ring spacer is measured, and the algebraic sum delta 2 is the axial play of the double row conical bearing. The utility model which is suitable for the axial play measuring field of medium and miniature double row conical bearings with the inner ring spacer and the outer ring spacer has the advantages of simple structure, low manufacture cost, precise measure and high efficiency.
