Abstract
The spline pair needs to transmit large alternating torque and other directional loads, which causes the fretting wear of the spline pair to be serious, which leads to the failure of the spline pair connection and reduces the reliability of the entire transmission system. Therefore, it is of great significance to carry out research on fretting wear of spline pairs and improve the ability of splines to resist fretting wear. In this paper, based on the finite element method, a model considering the tooth fretting wear property of the agricultural tractor spline couplings model was developed to analyze changes of contact stress and relative slip distributions, in which the axis deviation was considered. The results show that axis deviation significantly increases the value of contact stress and relative slip in the spline couplings. With the increasing deviation, the value of contact stress and relative slip slightly raise accordingly. The friction coefficient shall not be too small when the system is lubricated. As a result, maintenance of the agricultural tractor transmission system can be required.
Highlights
The involute spline pair consists of internal and external splines
The dimensionless value of the representative stress is expressed by the ratio of the stress calculated by the finite element method and the average contact stress p ; the dimensionless value of the relative slip is expressed by the ratio of the slip calculated by the finite element method and the radial contact width a
In order to verify the accuracy of the finite element analysis results, in this paper, the effect of the axial displacement is analyzed by making a tribological test
Summary
Compared with other key couplings, spline pairs have the characteristics of automatic centering, good tooth surface contact, long life, and large bearing capacity. They are widely used in agricultural products, especially in high-power tractor drive systems. A lot of researches related to the spline analysis were carried out and many new models considering tribological property were proposed as well, it should be noted, there were very few related studies on the axial eccentricity of the internal and external splines
