“…When calculating the meshing stiffness, the analytical method is widely used due to its efficiency and accuracy when comparing with FEM (finite element method). Zhang [7] studied the meshing stiffness when accounting for loading and stressing distribution on helical gears; the results matched well with the Finite Element Analysis (FEA)method. Howard [8] used the FEA to calculate the could not be affected by a different dynamic model.…”

The gear is one of the important parts of a rotary gearbox. Once catastrophic gear failure occurs, it will cause a great threat to production and life safety. The crack is an important failure factor causing changes in time-varying stiffness and vibration response. It is difficult to effectively identify the vibration response and meshing stiffness changes when there is a fine crack in the gear. Therefore, it is of great importance to improve the accuracy of meshing stiffness calculation and dynamic simulations under micro-cracks. Investigations of meshing stiffness and the vibration response of a gearbox is almost all about fixed gear shape parameters. However, the actual production process of gear system needs to change gear shape parameters. In this paper, the meshing stiffness and vibration response of the dynamic simulation signals of gear teeth with different crack depths at different tooth shape parameters (the pressure angle, the modulus, and the tooth number) were calculated, respectively. The influence of cracks on the vibration response was investigated by the fault detection indicators, the Root Mean Square (RMS), the kurtosis, and the crest factor. The result shows that when the pressure angle and modulus change, the vibration response changes erratically. However, when the tooth numbers change, the vibration response changes regularly. The results could be a guide for choosing gears in different shape parameters when system stability is the aim.

Gears are the back bone & one of the most critical components in mechanical power transmission systems.Among the contributors in gear set failure bending and surface strength are identified as one of the contributors which plays major role in it. Thus, to reduce the failure of gear & for optimization of gear design analysis of stresses resulted into major are of interest. In this paper the major focus is on studying stresses and pressure distribution using analytical and finite element analysis for the characteristics of an involute helical gear system. To estimate & identify the various stresses and other important parameters of helical gears, a threedimensional solid model of set of gears is generated using the Computer Aided Design Software Pro/Engineer, which is currently being known as a strong tool for solid modeling. The analytical investigations are carried out by varying the load on gear. This paper also considers the study of contact stresses induced between two gears. To determine the contact stresses between two mating gears, the analysis is carried out on the two gears. A pair of standard helical gears is used and analysis is performed on by FEA Software Altair HYPERWORK OptiStruct solver using the following two conditions for the same power output (i) gear pair made of nylon; and (ii) other pair made of stainless steel. The results obtained from Altair HYPERWORK OptiStuct, are compared to investigate the possibilities of using Nylon as an alternative material for gears against traditional as steel in power and/or motion transmission sector.
