Abstract
The invention discloses a bearing axial play measuring method, and belongs to the technical field of bearing play measuring. The measuring method is achieved based on a bearing axial play measuring device. The measuring method comprises the steps that an end is clamped on an outer ring of a bearing, and the measuring head of a dial indicator abuts against the outer side of a wheel hub hole; a sleeve is forcefully pushed rightwards, force is transmitted until a force applying unit applies rated push force rightwards, and the end drives the outer ring of the bearing to move rightwards; the measuring value of the bearing axial play can be obtained by reading the number of a pointer of the dial indicator. Due to the fact that the force applied by the force applying unit is controllable, the force applied to outer rings of bearings of the same batch can be consistent by controlling the force applied by the force applying unit, and the measured bearing axial play value is more accurate.
