چکیده

Purpose. Development of a mathematical model heavy loaded gear transmission with self-aligning drive gear; evaluation the dynamic load on in alignment process. Methodology. The calculation schematic and equations relative motion are formed using methods rigid body dynamics. Analytical expressions for self-alignment time, collision velocity during factor obtained by integrating an ordinary differential equation. Methods linear theory oscillations used to determine factor. Findings. article investigates state-of-art design models gear. An equation moving part has been It is shown that proposed hypotheses, movement can be reduced rotation about instantaneous axis. influence geometric parameters ball mill loads open investigated. speed dependences tooth mesh misalignment angle inertial have obtained. dependencies were calculate time 5.5 6.5 (central discharge mill). real range angles parameters, several orders magnitude less than teeth re-engagement. In presence variable component angle, will constantly make strikes; depending current value significant. when assessing efficacy gears, it necessary take into account possible increase loads. calculated nominal mills. Originality. A dynamics duty machine drives developed. quantitative assessment internal mills carried out. Practical value. method determining containing

Machine Theory Dynamic tooth loads of planetary gear sets having tooth profile wear

A computational model of a planetary gear set is employed to study the influence of surface wear on the dynamic behavior of a typical planetary gear set. The overall computational scheme combines a wear model that defines geometric description of contacting gear tooth surfaces having wear and a deformable-body dynamic model of a planetary gear set. The wear model employs a quasi-static gear con...
