Analytical Crack Propagation Scenario for Gear Teeth and Time-Varying Gear Mesh Stiffness
In this paper an analytical crack propagation scenario is proposed which assumes that a crack propagates in the tooth root in both the crack depth direction and the tooth width direction, and which is more reasonable and realistic for non-uniform load distribution cases than the other presented scenarios. An analytical approach is used for quantifying the loss of time-varying gear mesh stiffnes...

متن کاملGenetic Algorithm for Optimizing Noiseless, Non-Lubricated Helical Gear Pair
This research is motivated by optimal designing of bevel gear pair for transmitting more power between shafts in the machine tool without noise and without lubricating oil. In this research, the parameters such as power, efficiency, weight and centre distance have been optimized since the parameters are the central part of the gear problem. The sub problem of reducing the noise, running without...
متن کاملA Differential Planetary Gear Model with Backlash and Teeth Damage
Planetary gear trains can be more compact and efficient as power transmissions than fixed axis gear trains but are also more complicated and less understood in terms of vibration health monitoring. A practical differential planetary gear train, which combines two inputs and one output, is studied using multi-body dynamics software. Backlash between the sun gear and planet gears are precisely sp...
متن کاملNonlinear Contact Analysis of Gear Teeth for Malfunction Diagnostics
Gearboxes sustain a variety of faults such as broken-shafts, eroded, broken, or missing teeth, and even broken-cases. Casing mounted accelerometers can detect fault patterns but the signals are complicated and difficult to interpret. This study considers the tooth loading of ideal gears and gears with defects. A large industrial gearbox used in a 12m electric mining shovel is modeled. The nonli...
