Profile Relief and Noise Excitation in Helical GearsDonald R. Houser, Ph.D
One of the problems posed by them being loaded into tubes more than 15 metres in length is the risk of these grains breaking if they are allowed to simply fall freely without taking any precautions; this is one of the solutions of the prior art for producing a dense loading. ...

ONLINE EXCLUSIVE: Helical or Not Helical? How Helical Gears Impact the Performance of Planetary SystemsGerhard Antony
In consequence, a need arises for a more structured design intended to provide solutions which are feasible and stable for most of the helical gear design problems. As a result, genetic algorithm has been used as the optimization approach and their relative performances by varying the parameters ...
The prediction of gear noise may normally be treated as a classical source-path-receiver problem. Usually, the excitation occurs in the gear mesh and the path includes the transmission of forces and motions through the shafts and bearings to the gear housing, which in turn radiates the noise....
