Calculated as the arc length on the average circle of the tooth height
The analysis of the accuracy of the cycloidal pinwheel reducer reflects the main technical indicators of the performance of the cycloidal pinwheel reducer including motion accuracy, transmission stability, load uniformity and meshing backlash. In order to control these indicators, some single-item and comprehensive precision projects were proposed for testing and evaluation when designing and manufacturing cycloidal gears. Used to control the meshing backlash of the cycloidal pinwheel reducer. The selection of the tooth thickness limit deviation can be applied to the 14 standard deviation codes specified by the involute gear standard. The value corresponding to the standard deviation code is divided by the height average circle radius of the cycloid gear to the angle of the corner modification angle. Definition of the tolerances in the II tolerance group, mathematical model and test method: One tooth tangential comprehensive tolerance f: When the measured cycloidal gear meshes with the ideal needle wheel, it is actually within one pitch angle of the measured gear. The maximum amplitude value of the difference between the corner and the nominal corner is calculated as the arc length on the average circle of the tooth height. The definition of one tooth radial comprehensive tolerance f: the maximum variation of the center distance of the double-biting in the pitch angle of the measured gear when the measured cycloid gear is double-sided with the ideal pin wheel. The pitch limit deviation ±f is defined as the difference between the actual pitch and the nominal pitch on the average tooth height circle. The tolerance of the tooth profile f is defined as the normal distance between the two equidistance curves of the actual tooth profile in the toothed working part of the end section (the equidistance curve is obtained on the basis of the theoretical tooth profile according to the principle of equidistance modification) The two curves, the equidistant curve can accommodate the actual tooth shape to the greatest extent). When the pin teeth are in contact with the tooth profile of the cycloid gear to be measured and move in a planetary motion, the center of the pin tooth will depict an equidistant curve of the cycloidal profile. The curve can be acquired by the computer through the sensor, and then the program is used to generate two theoretical equidistant cycloids to achieve maximum tolerance of the curve, and the tooth profile error can be calculated.
