Problems solved by technology
[0002] At present, in shield machines, wind power and other fields, the widely used high-precision tapered roller bearings cannot be mass-produced, and there is no effective means to detect the cylindricity and energy consumption of large bearings. For large bearing rings with a diameter of more than 2 meters, due to the huge size of the parts , high accuracy requirements for cylindricity measurement and the limitations of the measurement environment, the existing measurement methods of contact sensors and workpiece turntable rotation are difficult to meet the measurement requirements

The invention relates to a bearing cylindricity measuring instrument, in particular to a large bearing ring cylindricity measuring instrument. The instrument comprises a telescopic gauge stand, a basic platform, a numerical control air floatation platform, a placement base, a buffer device and a Z-axis stand column, wherein the placement base and the buffer device are alternately arranged on the basic platform at intervals in the circumferential direction; the numerical control air floatation platform is arranged on the basic platform; the Z-axis stand column is arranged on the numerical control air floatation platform. The telescopic gauge stand is arranged on the Z-axis stand column; and the numerical control air floatation platform is used for driving the telescopic gauge stand to rotate, so that cylindricity measurement of the bearing ring placed on the placement base is realized. Through the implementation form of the non-contact measurement mode in the large bearing cylindricitymeasurement, the influence of contact measurement on the stability of the measurement rod is avoided, so that the measurement accuracy is ensured.

technical field [0001] The invention relates to a bearing cylindricity measuring instrument, in particular to a large bearing ring cylindricity measuring instrument. Background technique [0002] At present, in shield machines, wind power and other fields, the widely used high-precision tapered roller bearings cannot be mass-produced, and there is no effective means to detect the cylindricity and energy consumption of large bearings. For large bearing rings with a diameter of more than 2 meters, due to the huge size of the parts , High accuracy requirements for cylindricity measurement and the limitations of the measurement environment, the existing measurement methods of contact sensors and workpiece turntable rotation are difficult to meet the measurement requirements. Therefore, there is an urgent need for a fast and precise measuring device for the cylindricity of a large bearing ring. Contents of the invention [0003] In view of the above problems, the purpose of th...
