“…This is because not only the A þ point is in the state of single pair of teeth but also the calculated comprehensive curvature radius is the smallest in the single tooth meshing area. In addition, according to Wei et al 21 and Yang, 22 the tooth root near the pitch line is prone to pitting, and consequently, the maximum contact stress at point A is reasonable, while for the lower boundary point C of the single tooth meshing area, there also is significant contact stress when the two gears are in single tooth contact.…”

The conditions of correct gear engagement of a pair of involute gears and the principle of geometric relationship of involute tooth profile are derived to determine the pitch point of externally meshing non-variable multi-modulus spur gear pairs into the double tooth engagement region. The Hertzian contact stress model is used as the basis to derive the contact stress calculation equations for pitch point and other characteristic contact points, and the variation of the contact stress distribution on the contact line with the module ratio is analyzed. The results demonstrate that when the number of teeth of the gear pairs is determined, the larger the value of the module difference, the easier it is for the pitch point of the gear pairs to be in the double tooth meshing zone. Except for the double tooth meshing out point, the contact stress decreases with the increase of module ratio, and the maximum point of contact stress is at the upper boundary point of the single tooth meshing zone.

This process is developed into an automatic program by using Visual Basic language software, and the solution of building a network-based psychological counseling information platform for colleges and universities is introduced, and the Guan Qian technology involving Xiamen is introduced. It provides a scientific, advanced and efficient modern management platform for Gaoling's psychological counseling and management work, and realizes effective counseling and prevention of college students' psychological crisis. This paper analyzes the current development status of ideological and political education in colleges and universities and the problems that need to be solved urgently, and analyzes the hidden depth behind the application dilemma of the current psychological counseling method from the four aspects of education subject, object, mediator and ring body. Hierarchical reasons.

“…Hence, the critical factor ( σ V s ) and also separately contact stress and sliding velocity have been considered and analysed by many researchers in gear design. Using Hertz equation, the magnitude and location of maximum contact stress have been analysed by Yangang Wei . The dynamic characteristics and static stress distribution during meshing of gears were analysed by F. R. M. Romlay .…”

The effects of sliding velocity in a spur gear for a tooth sum of 100 (altered by ±4%) with constant centre distance have been studied. The product of contact stress and sliding velocity (σ Vs) factor is calculated for varied profile shift. The effect of Hertzian compression, bending and shear deflection on sliding velocity at points along length of the path of contact has been computed. The scanning electron micrographs at pitch point C show that negative alteration in tooth‐sum gears is better compared with standard and positive alterations in tooth sum.
