Dynamic Distribution of Load and Stress on External Involute Gearings


The influence of additional dynamic loads on the distributions of load, flank pressure and tooth root stress are shown. The additional dynamic loads excited by the variations of mesh stiffness and influenced by tooth deviations and modifications are calculated and used as input for the calculation of the distributions of load and stresses in the plane of action. The programs used for these calculations were developed at the Institute of Machine Elements at the Dresden University of Technology. Very efficient calculations are obtained by using specially developed calculation algorithms. An extensive graphic presentation of the calculation results is included. The same connection of the calculation of load distribution with the calculation of dynamic loads is also possible in principle on the basis of very similar programs (LDP & DYTEM) developed at the Ohio State University. The calculation results are compared with dynamic loads and transmission errors measured on test rigs in the gear lab at the Ohio State University.
