Portable bearing clearance measuring device

Abstract

The invention provides a portable bearing clearance measuring device, comprising: a bearing fixing mechanism, for supporting and fixing a bearing to be measured, wherein the bearing fixing mechanism comprises a bracket, a fixing plate, a movable pressing plate, a lock nut, a mandrel, and the bracket comprises two pillars arranged in parallel, a quadrangular connecting plate fixedly connected withthe pillars, and a base placed at bottom of the pillars; a bearing shifting mechanism, for providing power to move the bearing, wherein the bearing shifting mechanism comprises a pry bar and a pry barbracket, wherein middle of the pry bar is provided with a pin, and the pin is clamped on the pry bar bracket, as the fulcrum of the pry bar, and one end of the pry bar can be pressed to drive the other end to rotate, thereby driving the outer ring of the bearing to move; and a clearance measuring mechanism, wherein the clearance measuring mechanism includes a magnetic table and a dial indicator.The device occupies small space, is convenient to carry, is suitable for use in production field, adapts to measuring bearing clearance with different sizes, has accurate measurement data, reduces influence of human factors, and improves bearing process quality and work efficiency.

Description

technical field [0001] The invention belongs to the technical field of bearing clearance measurement, and in particular relates to a portable bearing clearance measurement device. Background technique [0002] Bearing clearance refers to the amount of movement when the inner ring or the outer ring of the bearing is fixed when it is not installed on the shaft or the bearing box, and then the unfixed side is moved radially or axially. According to the direction of movement, it can be divided into radial clearance and axial clearance. The size of the clearance during operation (called working clearance) has an impact on the bearing's rolling fatigue life, temperature rise, noise, vibration and other performance. [0003] The clearance measurement before the bearing installation on the production site is generally measured by a micrometer after rolling the lead wire, or by a dial indicator. The above methods are greatly affected by the operation level and proficiency of the per...
