一种带内外隔圈双列圆锥轴承轴向游隙的测量装置和方法

The present invention belongs to the field of mechanical part measuring technology. The measuring device consists of dial test indicator, locking screw, dial test indicator seat, fall measuring rod, fall measuring rod seat, screw nut, fall pad, fall limiting ring, spring washer, screw and horizontal meter calibrating block. The measurement process includes first measuring axial distance t1 between the inner ring non-reference end and the outer ring reference end of single row conical bearing, then measuring the axial distance t2 between the two ends of inner and outer spacer rings of the single row conical bearing with inner and outer spacer rings, and calculating the algebraic sum t1+t2 as the axial backlash of the double row conical bearing. The present invention is simple in structure, low in cost, accurate in measurement, and high in efficiency.
