Opis:
When gears change their distance along the off-line of action (OLOA) direction, this affects the distance between the working surfaces of the meshing teeth along the line of action (LOA). This effect is usually neglected in studies. To include this effect precise equations are derived for spur gears. The analysis is carried out for the general case of spur gears with shifted profiles frequently used in the industry. The influence of OLOA gear displacement on LOA direction is also a function of gears parameters. An analysis is conducted, and the impact of parameters such as module, pressure angle, gear ratio, and the number of teeth is determined. As an example, a simulation of a 12 DOF analytical model is presented. The movement of gears along OLOA is caused by a frictional force that can be high during tooth degradation e.g. scuffing. Results show that when the movement of gears along the OLOA direction is significant, its influence on the distance between the mating teeth should not be neglected.

Opis:
Torsional vibrations occur during drive systems operation. They may be especially hazardous if the freQuency of input functions is close to resonance frequency or if system resonance frequency is equal to subharmonic of input function frequency. What 's more, there is always a possibility of more than one resonance zone since the system is usually non-linear and multi-body. In design process of power transmission systems very important is correctly selection of the couplings parameters (especially flexibility). Couplings stiffness and damping have principle influence on shaft torsional vibrations. In case of power transmission with tooth gear the vibrations which are connected with dynamic forces in meshing. The paper presents influence of flexible couplings stiffness characteristics on dynamic forces in meshing. The investigations based on the measured couplings stiffness as well as damping and computer simulation ofpower transmission system with tooth gear operates at varying load. On the basis of conducted tests and analysis it may be stated that toothed wheels rotational speed increase does not always result in meshing dynamic forces increase. dynamic model ofdrive system with toothed gear is therefore a useful toolfor analysing couplings impact on meshing dynamic forces. This is illustrated by examples presented in current paper.

Opis:
This study relates to the research on improving analytical models of gears. A new analytical model of gear shaft with 5 DOF was proposed. Equations of vibration were derived without small-angle approximation and were presented in a form that could be implemented in Simulink. In order to determine the effect of the additional DOF, four popular models having 2 DOF, 4 DOF, 6 DOF and 8 DOF were investigated, too. The proposed model has 12 DOF in total. This number of DOF could be increased; this, however, would result in a greater difference between the considered models, thus making it more difficult to evaluate the impact of the additional DOF of shafts. As a benchmark, the dynamic meshing force in the considered analytical models was calculated. Simulations were carried out with and without friction. Additionally, for the 12 DOF model, the effects of the position of the centre of gear and the centre of mass were investigated.
