gear tooth

In recent years, many scholars have done a lot of research on gear modification, and there are many modification methods

A-F in the figure is the tooth direction error diagram of 24 teeth of the pit type large gear after

In order to facilitate the comparison with the parameters before the test, the smooth big gear after the test also

In order to make it more convenient and intuitive to compare the measurement data of smooth big gear and pit

The smooth big gear has 24 teeth in total, which are measured by full teeth. The changes of morphological parameters

The relevant parameters used are shown in the table. In order to solve the tooth surface of instant noodle gear,

The original 20 node finite element method is adopted, which takes the eight vertices and the midpoint of twelve edges

As one of the important components of gear stiffness, it is very important to calculate the matrix stiffness reasonably and

According to the semi empirical formula model, the contact stiffness is related to the contact load. According to the description

Gear pair 2 is selected to study and analyze the effect of gear geometric parameters on tooth stiffness. The curve

The gear pair parameters are selected for tooth stiffness simulation analysis. The selected gear pair parameters cover two different tooth

The tooth surface pitting model can be established through the gear modification parameter module in Fig. 1. By defining the

The parameters of gear pair are selected as the calculation object, and the contact stiffness of gear pair under Yang

According to the Hertz contact analysis theory, the geometric model of the contact end face of two cylinders as shown

In order to further study the dividing line of the number of teeth in the two cases, according to the

Under the same parameters, the author calculates the tooth thickness deviation of different tooth line radii in the same section,

When m = 4, z = 31, RT = 100 mm, 200 mm, 300 mm, 400 mm, respectively, measure the

In the process of gear meshing, the time-varying meshing stiffness is mainly related to the meshing force and deformation of

The relationship between the tooth root bending strain and the gear meshing stiffness is deduced. Therefore, the meshing stiffness of

The dynamic strain of tooth root measured by fiber Bragg grating sensor and piezoelectric strain sensor is analyzed. The dynamic

Since the early computer was not widely used, the method based on mechanics of materials to calculate the time-varying meshing

The dynamic simulation is carried out by using Benedict amp; Kelly model and time-varying friction coefficients obtained in Figure 2.8

In order to reflect the influence rule of parameters on the maximum circumferential stress, dimensionless radius of chamfered root of
