GEAR SHAPING AND SPLINE SHAPING VIDEO

Quick overview about the production methods of gear cutting. This video illustrates the basic generating method of a gear shaping machine. Several examples of external and internal gears and splines are produced.

WHAT MAKES A GEAR?

In this month’s TechBit we examine a few of the most common ways to produce gear teeth.

Methods of Gear Generation

GEAR AND SPLINE 101

So you have a gear (or a spline) and you don’t know what it is. Three basic things you should ask, what are the Pitch, Pressure Angle, and Circular Tooth Thickness. In all involute system gearing, these features define how the gear is made and are useful to understand when discussing gear and spline projects.

GEAR AND SPLINE 201

Have you ever wondered what the difference is between a “gear” and a “spline”? Or what a “Stub Tooth” is? If so, you might find the attached TechBit useful and informative. Please consider Doppler Gear for your next gear cutting, broaching or splining requirement.

HELIX AND LEAD 301

In previous TechBits we discussed the basic features of “spur” (straight toothed) gears and splines. What if your gear teeth are “helical” (angled) or you have a “worm”? How is that defined? How is it measured? The following TechBit explores the concepts of Lead and Helix and should be useful to anyone working with gears, worms, and even basic threads.

HOBBING VIDEO

If you’ve ever wondered how gear teeth are cut, this one-minute video on hobbing is for you.
