Why helical gears are better than spur gears?

Helical gears are more durable than spur gears because the load gets distributed across more teeth. Hence, for a given load, the force will be spread out better than with a spur gear, resulting in less wear on individual teeth. Spur gears can be really loud.

What is a CAD diagram?

What is a CAD drawing? A CAD drawing is a detailed 2D or 3D illustration displaying the components of an engineering or architectural project. Computer-aided design utilizes software to create drawings to be used throughout the entire process of a design project, from conceptual design to construction or assembly.

What do you mean by helical gear?

Helical gears are one type of cylindrical gears where the teeth are curved into a helix shape. Compared to spur gears (straight teeth), properly designed helical gears can have a larger total contact ratio which can improve vibration and noise. Badly designed helical gears can be noisier than well designed spur gears.
