Device and method for measuring diameters of internal and external raceways of wind power bearing

Abstract

The invention discloses a device and method for measuring diameters of internal and external raceways of a wind power bearing. The device comprises a ruler and a meter, wherein the left side and the right side of the ruler are respectively provided with a measuring bar, i.e. a left measuring bar and a right measuring bar respectively; the left measuring bar and the right measuring bar can be moved and fixed on the ruler; the left measuring bar and the right measuring bar can also be arranged on the ruler in the reverse direction for measuring; the left measuring bar and the right measuring are vertical to the ruler; the left measuring bar is provided with a fixed measuring head through a left fixed mount; the right measuring bar is provided with a moving measuring head through a right fixed mount; the meter is fastened and connected with the right measuring bar through a fixed bar; and a contact of the meter and the right end surface of the moving measuring head are in elastic contact. The method comprises the steps of adjusting the measuring device, actually measuring and judging whether the diameters of the raceways are qualified or not. The device can be used for measuring the diameters of the internal and the external raceways of the bearing, thereby improving the efficiency and the convenience of the measuring work.

Description

technical field [0001] The invention relates to a measuring device, in particular to a measuring device and a measuring method for the diameter of the inner and outer raceways of a wind power bearing. Background technique [0002] With the vigorous development of wind power generation, the demand for wind power bearings, an important component in wind power generation, continues to rise. At the same time, the requirements for manufacturing technology and measurement technology of wind power bearings are getting higher and higher. [0003] In the measurement of the diameter of the inner and outer raceways of wind power bearings, the ruler on the original measuring device used a hollow round iron tube, which caused large deformation due to its large expansion coefficient, resulting in low measurement accuracy; in addition, the original Some measuring devices use a spherical probe, which causes the probe to be too heavy, and the ruler is not close to the end face of the measure...

Problems solved by technology

[0003] In the measurement of the diameter of the inner and outer raceways of wind power bearings, the ruler on the original measuring device used a hollow round iron tube, which caused large deformation due to its large expansion coefficient, resulting in low measurement accuracy; in addition, the original Some measuring devices use a spherical probe, which causes the probe to be too heavy, and the ruler is not close to the end face of the measured piece during measurement, which requires a large measuring force during measurement, which makes the probe very easy. The wear also affects the improvement of measurement accuracy and accuracy; also due to the singleness of the original measuring device, when measuring the inner and outer raceway diameters of wind power bearings, it is not very convenient to use different measuring devices, resulting in efficiency Low; therefore, in order to overcome the above-mentioned shortcomings and shortcomings, it is the goal pursued by the technicians in this industry to develop and design new measuring devices and measuring methods, reduce the wear of the measuring head, and improve the measurement accuracy and efficiency.

In addition, the original measurement method firstly affected the repeatability of the calibration reference of the standard gauge block due to the excessive measuring force of the movable probe; secondly, the existing probe uses the entire steel ball, and its own weight has affected the measurement accuracy; and the measurement repeatability Poor, which directly affects product quality; the inconvenience of final measurement makes it take too much time to measure a bearing, and the measurement efficiency is low
