Combination gauge for abnormal bearing inner ring pore detection and detection method thereof

Abstract

The invention discloses a combination gauge for abnormal bearing inner ring pore detection. The combination gauge comprises a plug gauge and a ring gauge which is used in cooperation with the plug gauge. One end of the plug gauge is a detection end for detecting whether the size of a bearing inner ring pore conforms to the tolerance requirement or not and the other end of the plug gauge is a positioning end used in cooperation with the ring gauge. The position where the ring gauge corresponds to the bearing inner ring pore is provided with a positioning hole which is matched with the positioning end of the plug gauge in an adapted mode. The positioning end of the plug gauge and the positioning hole of the ring gauge are mutually matched and used for detecting whether the position of the bearing inner ring pore conforms to the tolerance requirement. The invention further provides a method for detecting the bearing inner ring pore with the combination gauge. The combination gauge for abnormal bearing inner ring pore detection is simple in structure, capable of effectively detecting whether the size and the position of the bearing inner ring pore conform to the requirements or not and convenient to operate as detection steps are simple. A detection structure can be conveniently and directly obtained through observation.

Description

technical field [0001] The invention relates to the technical field of detection of small holes on the inner ring of special-shaped bearings, in particular to a combined gauge for checking the small holes of the inner ring of special-shaped bearings, and an inspection method for checking the small holes of the inner ring of the bearing by using the combined gauge. Background technique [0002] Bearings are important basic components of various mechanical equipment, including outer rings, inner rings and balls. Among them, the accuracy of the bore size, roundness and taper of the inner ring of the bearing directly affects the accuracy and performance of the bearing. [0003] The inner ring of special-shaped bearings has a variety of structures, and there are many kinds of small holes on the inner ring of the bearing. When the size or position of the small holes deviates, the special-shaped bearing cannot be installed and used normally. Since the inner ring of the special...

Problems solved by technology

This detection method requires high air pressure stability, otherwise it will cause large errors, and it also requires high cleanliness of the inner ring of the bearing. When there are oil, dust and other pollutants in the small hole of the inner ring of the bearing, it will change The feedback value of air pressure, which affects the measurement accuracy
