Dynamic loads on the teeth of spur gears
WebMar 4, 2024 · The most important contributing factor of dynamic behavior is the stiffness of the teeth, which changes constantly throughout the operation. The calculation of gear stiffness is important for determining the load dis- tribution between the gear teeth when two sets of teeth are in contact. WebJan 26, 2024 · In this study, static and dynamic analyses of a spur gear pair with linear tip relief and longitudinal crowning were performed. Dynamic experiments were conducted to compare and verify the dynamic analysis results. On the basis of the theory of gearing, the mathematical model of a modified spur gear pair was established. In addition, a finite …

WebOct 1, 2024 · Tip relief modifications are a common design feature used in industrial practice to reduce dynamic tooth loading, noise, vibrations and wear in high-performance gears. This paper presents a novel implementation of a specific multibody model to include the effect of tip relief micro-modification on spur gears. WebA back-to-back gear rig (12 000 ft/min maximum pitch-line velocity) was used to demonstrate various causes of high-speed gear vibrations with either straight spur or helical teeth, the transducers being four strain gauges mounted on the gear shaft.
