Company Profile: Michigan Hone & Drill

As part of this expanded issue we’d like to offer an article that’s equal parts case study and company profile, describing why a finishing shop is devoted to the Sunnen equipment with which it made its start.

According to Ken Pape—who is president of the Parts Finishing Group, of which Michigan Hone & Drill is a member—whenever a part rotates on a shaft or a piston slides inside a bore the shape, size, and surface finish of that bore determine the quality of the interface between the moving parts. This principle is […]

Relative Curvature of Worm & Wheel with Straight Line Generatrix

You’re sure to benefit from reading this fascinating study presented by a gearbox specialist with Tata Steel on calculating—and better understanding—worm/wheel contact.

The contact on single enveloping worm gear drives is the line contact. The changing form of the worm across the face of the gear makes it impossible to derive a simple mathematical expression for the contact curvature. In addition, the combination of the lead angle of the worm and position of the pitch plane of […]

An Advanced Approach to Optimal Gear Design

Take two proven design approaches—Direct Gear Design and the Method of Dynamic Blocking Contours’ combine their best attributes, and the result is Advanced Gear Design. Read on to learn more.

The theory and practice of gear design is rich with examples of successful and sometimes outstanding combinations of various mathematical, manufacturing, and methodological approaches to the choice of the best parameters, defining the gear itself, its generating tools, and processes of generation and meshing of tooth flanks [1, 2, 3, and others]. Knowledge of involute […]

The Foundations of Function-Testing Gear Assemblies

There are many different ways of testing gears and the assemblies in which they are incorporated.

Functional gear testing could be defined as a series of tests that simulate the intended function of the product in an effort to determine whether an assembly operates within a specified performance range; quite simply, a method to test how well the assembly will function once it is applied to its intended purpose. In the […]

Battling Gear Infant Mortality

Sometimes a seasoned gear manufacturing machine is the most dependable, but close monitoring is required to keep it running at the peak of its productivity.

There is a common misconception in the industry that new equipment is more reliable than machinery in operation. In reality, the machines that have been in operation for a year or more and are a part of a condition monitoring program are actually more reliable than startup equipment. Statistics and industry studies confirm that the […]

Q&A with Jason Ray

Sales Manager, Clifford-Jacobs Forging Co.

You’ve been with the company for five years now, how did you come to join it?” I was originally trained as an engineer, and I was working with a company in an unrelated field that required a great deal of traveling—and this was right when I’d gotten married, too, so being on the road so […]

Terry McDonald: Site Safety

Equipment maintenance keeps your machines running smoothly, but have the personnel assigned to the task received the proper training to handle it safely? Put safety first and avoid unnecessary injuries.

Do you put safety first in your workplace? Are you a safety conscious person… and I mean really safety conscious? I don’t know anyone who’s not in favor of safety, but I know very few people who actually put safety first. We don’t really consider safety before production, for instance, nor do we really consider […]

Part 2: Don’t compromise a quality gearbox by scrimping on seals and filters

You don’t want to compromise a quality gearbox by scrimping on seals and filters. Here’s the conclusion of a two-part series, this one devoted to filtration.

Oil cleanliness is essential for gear unit reliability. To achieve this cleanliness in force-feed lubrication systems filters should be the last piece of equipment prior to the lubricant entering the housing. All filters should have a minimum efficiency of 90 percent at the specified micron rating. The life of bearings and gears increase with improved […]
