Web1 mei 2015 · Helical gears, by contrast, generate significant axial forces in the gear mesh. They also exhibit more sliding at the point of tooth contact, adding friction forces into the mix. Helix angles in gearboxes usually fall in a range of 15 to 30 degrees. As the angle increases, both the axial forces and sliding contact increase. 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.
