Northwest Pennsylvania’s Oil Region has a long history in manufacturing. Many of the widgets that made oil extraction and processing possible were ...

I rambled on about herringbone gear in my last posting but still have more to share on these once commonplace gears. Today we’ll cover the use of c...

It was brought to my attention that the graphics used in my recent “herringbone” postings actually show double helical gears. I have a great suppor...

What are the manufacturing methods used to make bevel gears used in automotive differentials?

A recap of the AGMA 2010 Fall Technical Meeting.

Zerol bevel gears are the special case of spiral bevel gears with a spiral angle of 0°. They are manufactured in a single-indexing face milling process with large cutter diameters, an extra deep tooth profile and tapered tooth depth.

With the right selection of nonstandard center distance and tool shifting, it may be possible to use standard tools to improve the gear set capacity with a considerable reduction in cost when compared to the use of special tools.
