  • Computer Simulation of Gearing about Load, Stress and Wear in Meshing Process
    Mechanical Science and Technology, 2020
    Co-Authors: Pan Er
    Abstract:

    Considering the basic ideas of boundary element method(BEM),we devide the boundary curve into many units and nodes, analyse the nodes meshing and wear process of these nodes, utilize parametric cubic spline curve to simulate the worn Flank of Tooth, so as to analyse gear meshing and wear. We also developed a software, made computer simulation of load,stress and wear in gear meshing,the result is in agreement with actual situation on the whole.

  • Computer Simulation of Wear in Meshing Process of Involute Cylindrical Gear
    Journal of Shanghai Jiaotong University, 2020
    Co-Authors: Pan Er
    Abstract:

    Considering the basic ideas of boundary element method( BEM) ,an involute cylindrical spur gear can be simplified to the terminalface so thatthe three- dimensional meshing is turned into plane mesh- ing.This paper deviated boundary curve into many units and nodes,analyzed these nodes meshing and wear,utilized parametric cubic spline curve to analogy wearing Flank of Tooth,so as to analyze gear meshing and wear.A setof software was programmed.Itachieves the dynamic simulation of load,stress and wear in the process of mesh.The resultagrees well with the general wear regularity.

  • Virtual prototype technology based fatigue life analysis of gears
    2010 International Conference on Mechanic Automation and Control Engineering, 2010
    Co-Authors: Zhang Jian-cheng, Lei Bao-zhen, Zhang Qing-xia
    Abstract:

    A virtual prototype of a certain caterpillar drive system is established based on virtual prototype technology in the article, the dynamic load spectrums in operation on different work sections of drive system gears are obtained through a simulation riding test. Applying finite element technology on three-dimensional contact stress dynamic analysis, the course of contact stress in Flank of Tooth area and bending stress in root of Tooth area changes following time has been got for drive system. Load spectrum of full-life periodicity for drive system gears is obtained using fatigue reliability theory, fatigue reliability analysis of gears is then employed. Thus fatigue life of drive system gears under various work conditions and different degree of confidence is obtained conveniently too, which can provide a theoretical basic for optimum structure design, maintenance and life prediction of gear system.

  • The Theoretical Analysis and Experimental Study on the Distribution Characteristics of Motion Parameters in the Process of Honing Gear
    Key Engineering Materials, 2014
    Co-Authors: Cheng Zhang, Guo Xing Liang, Ming Lv, Shi Ying Wang
    Abstract:

    Gear honing processing is a kind of processing method which belongs to the point-contact generating gear finishing. Its movement form is equivalent to a pair of gears transmission which the surface of the gear-honing-tool is adhered a layer of grinding grain. When it works in rolling processing, the contact-point between the workpiece and gear-honing-tool is moving. Then the moving point becomes a line in the space, and with the gear-honing-tool being in axial play, a standard Flank of Tooth is finished. Using the gear meshing principle, kinematics model of relative sliding velocity in the contact-point between the workpiece and tools is established, based on which the contact-line equation. and acceleration equation. at the contact-point are derived. The contact-line is solved in a given parameters of the workpiece and tool in MATLAB. The theoretical derivation and experimental results show that the speed in diverse along the direction of the Tooth depth is the main reason for the roughness value and surface texture of workpiece. The acceleration of contact-line at the Tooth Flank is different, and it is leading reason that the processed workpiece gears appear profile distortion. Finally, the testing system is established for researching honing gear process. It is showed in the results that the acceleration difference can lead to the CBN abrasive falling away from gear honing tool, and even the "anti-cutting" phenomenon.
