Background
The gear is widely applied in the mechanical field, is the simplest and the most basic transmission unit and transmission mode, and is widely applied in classification, and can be directly divided into a gear set and an external gear from an application end. The gear set is transmission generated by meshing only two or more gears or tooth profiles, and the gears are constituent units of equipment; the external gear is arranged on the outer side of an output shaft of equipment or a matched part to form a driving unit, and the external gear can be collectively called as an application end gear; the key size and tolerance of the external gear can be basically determined by machining corresponding gear grades and the like, but the tolerance and the installation tolerance of the gear installed on the output shaft of the equipment can cause the tolerance of the reference circle run-out of the gear to be out of tolerance due to the tolerance and the installation tolerance of the output shaft of the equipment, and for an application end, the run-out directly influences the stress and the precision of the gear in the application process. After the existing equipment is provided with a gear, two methods are adopted for measurement: firstly, a measuring bar and a dial indicator are used for manually placing and measuring the measuring bar; secondly, roughly measuring the flange;
the manual measuring method adopting the measuring bar has the following defects: the diameters of the measuring rods used by the gears with different moduli, namely the gears with different sizes, are different, so that the measuring rods need to be replaced every time and are directly contacted with the gears, and after the gear measuring device is used for a long time, the measuring rods are easily worn, so that the measured value is inaccurate; the measuring rod is used for measuring, the runout of each tooth and adjacent teeth needs to be measured, the gear of N teeth needs to be placed and measured for N-1 times every time, and the efficiency is extremely low; the measured value is different due to the deviation of the position of the measuring rod in the upward direction of the gear shaft, particularly, the position of the measuring rod arranged between the gear teeth is inclined on the bevel gear, the measuring rod is arranged, the arrangement is not stable or the position has deviation, and therefore, the measured value is inaccurate.
Rough measurement flange method has the following defects: the inner side of the excircle measuring head is easy to wear, so that the measurement is inaccurate; the measuring point is the gear excircle runout, and the measured value is inaccurate for the non-gear meshing working face of circle in addition.
