RISEffect of Axial Vibrations on the Dynamics of a Helical Gear Pair
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a linear dynamic model of a helical gear pair has been developed. The model accounts for the shaft and bearing flexibilities, and the dynamic coupling among the transverse, ...
Planetary Gear Train Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A model to simulate the dynamic behavior of a single-stage planetary gear train with helical gears is developed. The three-dimensional dynamic model includes all six rigid body motions of the ...
Dynamic Analysis of a Multi-Mesh Helical Gear Train
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the dynamic behavior of a multi-mesh helical gear train has been studied. The gear train consists of three helical gears, with one of the gears in mesh with the other two. ...
A Transient Mixed Elastohydrodynamic Lubrication Model for Spur Gear Pairs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, a transient, non-Newtonian, mixed elastohydrodynamic lubrication (EHL) model of involute spur gear tooth contacts is proposed. Unlike the contact between two cylindrical rollers, ...
Load-Independent Spin Power Losses of a Spur Gear Pair: Model Formulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A physics-based fluid mechanics model is proposed to predict spin power losses of gear pairs due to oil churning and windage. While the model is intended to simulate oil churning losses in ...
An Ease-Off Based Method for Loaded Tooth Contact Analysis of Hypoid Gears Having Local and Global Surface Deviations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Actual hypoid gear tooth surfaces do deviate from the theoretical ones either globally due to manufacturing errors or locally due to reasons such as tooth surface wear. A practical methodology ...

Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, the results of an experimental parametric study of the combined influence of shaft misalignments and gear lead modifications on the load distribution and tooth bending stresses ...
A General Approach to Locate Instantaneous Contact Lines of Gears Using Surface of Roll Angle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Determining the locations and orientation of potential instantaneous contact lines between two contacting tooth surfaces of gears is one major step in the prediction of unloaded and loaded gear ...
Experiments on Nonlinear Dynamic Behavior of an Oscillator With Clearance and Periodically Time-Varying Parameters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A number of experiments on a physical system with clearance having combined parametric and external forcing excitation are presented. The data demonstrate several nonlinear phenomena that exist ...
Effect of Involute Contact Ratio on Spur Gear Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influence of involute contact ratio on the torsional vibration behavior of a spur gear pair is investigated experimentally by measuring the dynamic transmission error of several gear pairs ...
