Epicyclic gearing - Wikipedia

Web1 May 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. Web26 Jan 2015 · In general, planetary (epicyclic) gearboxes can carry higher power density (Hp/lb) than a two spur gear train of similar weight. But the answer to your question - which is better - really depends on the application. One major difference is that epicyclic input and output shafts are on the same axis (co-linear). baidu aria2

A common use of differentials is in motor vehicles, to allow the wheels at each end of a drive axleto rotate at different speeds while cornering. Other uses include clocks and analog computers. aqualyx jak podawać youtube
