Overton Gear and Tool Corporation

Bolstered by capital investments and its entry into the production of large-diameter, high-precision bevel gearing, this company has enjoyed explosive growth in recent years.

It’s an interesting proposition to consider: one company purchases another, thereby increasing its capabilities and product offerings in one fell swoop. The challenge, however, involves incorporating the purchased company’s capital assets into the existing structure — as Overton Gear found when it acquired Illinois Gear in May of 2005. “In addition to moving in the […]

Holding the Line

Whatever your product line, there is a work holding device to fit your particular application. Here’s a guided tour by a recognized authority.

As chief designer for Speedgrip Chuck, Inc., I have a fascinating job. I’ve been involved in the design and building of work holding devices for more than 25 years. There have been lots of changes during that time, and ever-increasing requirements: parts that used to be ground are now turned, formerly turned and machined parts […]

Calculating the Inverse of an Involute

In many variations on a central theme, the involute tooth form is used in a vast array of product designs. Read on for a discussion of two useful functions.

The involute tooth form is the only tooth form that provides true conjugate action normal to the tangency of the tooth curves passing through the pitch point. The ramifications of this property give the involute gear family the ability to transmit constant angular acceleration without slippage. In a special case of the straight sided rack: […]

Terry McDonald: Site Safety

It’s a given that sharp tools can be dangerous, but dull tooling can cause injuries as well. Keeping edges sharp–and operators protected–is central to workplace safety.

I have to admit it, I’m a Food Channel junkie. The reason I bring this up is that the other day, while I was watching TV, I saw an episode concerning knife sharpening which had a graphic stating that dull knives are the leading cause of accidents in the kitchen. This reminded me of my […]

Tooth Tips: William Crosher

The following is the second of a two-part column on the importance of factoring backlash into your gear mesh designs.

In the present day a precision reducer's backlash is typically three to six arc minutes, and on an eight inch pitch diameter that is a deflection of 0.0035 to 0.0070. What applications such as indexing may require is an inclusive assessment of the total deflections. Backlash in precision drives should include the no-load portion of […]

Q&A with Jeff Myers

General Manager, Schwartz Precision Gear Co.

I’ve read that the company was founded in 1959, is that correct? Yes, by a man named Frank Schwartz. As the story’s been told to me, he owned a company called Schwartz Boring, which landed a contract from NASA to provide guidance systems for the Redstone Missile Program. Well, he was buying the precision ground […]
