Description
technical field [0001] The application relates to the technical field of vehicle accessories detection, and in particular, to a detection tool for the clearance of a tapered bearing of a brake drum assembly. Background technique [0002] Usually, when the brake drum assembly is assembled, a certain amount of axial clearance needs to be reserved during the installation of the tapered bearing. like figure 1 As shown, the existing brake drum assembly is mainly composed of a brake drum 1, a shaft head 2, a conical bearing 3 and other components, wherein the axial clearance of the conical bearing 3 is: when there is no load, when the inner ring is fixed The amount of movement of the outer ring relative to the fixed inner ring in the axial direction from one extreme position to the other extreme position. At present, most of the industry, according to experience, use a certain torque to tighten the bearing lock nut 4, and then loosen it by a certain angle to control, because the...
