What is the main advantage of a helical gear over a spur gear?
The primary advantage of a helical gear over a spur gear lies in its ability to provide smoother, quieter operation and higher load capacity due to its angled teeth and gradual tooth engagement.
What is the primary advantage of a helical gear over a spur gear in power transmission applications?
The primary advantage of a helical gear over a spur gear in power transmission is its significantly smoother and quieter operation due to the gradual, continuous engagement of its angled teeth, leading to reduced vibration and increased load capacity.
What is the primary purpose of an idler gear in a gear train?
An idler gear’s primary purpose in a gear train is to reverse the direction of rotation of the driven gear or to bridge a distance between shafts without altering the overall speed ratio.
