The principle of making the gear meshing process diagram
In order to achieve the final ideal state of the gear design, it is necessary to strictly control the size and shape indicators, and among these indicators, the curves are directly related to the machining positioning accuracy. The selection of measurement parameters during the deviation topology detection shall satisfy:
1 The tooth profile error shall be measured in the middle of the tooth width, and the left and right side tooth faces of the gears distributed along the circumference of not less than four teeth shall be measured. The measured tooth height shall be greater than or equal to the working height specified by the pattern.
2 Reasonable determination of the definition of the length of the tooth width, the measurement range of the aluminum alloy ladder generally takes the 1880 tooth width part at both ends, and the deviation is not included.
The basic principle of the meshing process diagram is: when a pair of gears are rotating, if there is an error in the involute trajectory, when the rotation speed is kept constant, irregular rotation will occur, and the deviation will be numerically reflected. size. The maximum and minimum contact paths of the gear pairs can be obtained by using the meshing process map.
The meshing vehicle lubricating oil error in the meshing process diagram is caused by the ring gear radial runout, tooth profile error, pitch error and pressure angle error. The integrated gear rotation quality is reflected, but the single item error is separated from the curve. More difficult. Based on the difficulty of analyzing the characteristics of one-way error, two methods are used to solve the problem: one is to determine the noise of the gear pair from the type and amplitude, and the other is to analyze its characteristic points.
For example, there is a sudden jump point on the curve, and the sudden jump point can be divided into two cases: when there is a sudden jump point in the positive direction, it indicates that there is a bulge caused by dirt, burrs or bumps on the tooth surface; The convex jump point of the direction is because the tooth surface has a dent. In normal work, the meshing process diagram inspection is often used, supplemented by the one-way error measurement map analysis required before this, to comprehensively evaluate the gear transmission accuracy, and the results are satisfactory.
