FEATURES

Lubrication Engineers, Inc.

What was originally founded by three salesmen looking to provide a superior lubricant to the manufacturing industry has grown into a successful, wide-reaching business with customers and influence all over the world.

In 1951, three men took a risk. They left the company they worked for behind and ventured out on their own to provide the clients and industry they served with a superior lubrication product. Now, more than 60 years later, their legacy lives on at Lubrication Engineers, Inc. In the early years, the company’s products […]

The Efficiency of a Simple Spur Gearbox — Thermally Coupled Lubrication Model

This paper discusses how efficient a simple dip-lubricated gearbox is in a thermally coupled lubrication model, which includes elastohydrodynamic (EHL) friction losses in gear teeth contacts as well as bearing, seal, and churning losses.

Introduction The efficiency of drivetrain components is quickly becoming a significant research area pushed by the intensifying quest for improved fuel economy in automotive vehicles. Emission-controlling regulations are becoming stricter, owing mainly to environmental issues, such as air contamination, but also due to the depletion of oil deposits and the resulting high fuel prices.  Pursuing […]

Machine Involute Splines and Serrations with Rotary Broach Tools

Rotary broaching is not just for machining hexagon holes in screws. Here, you’ll learn more about the new product innovations and advanced techniques that continue to shape the broaching industry today.

Of the many ways to machine a form suitable for a gear, rotary broaching is not often the first considered. Precision grinding, broaching, EDM, and hobbing all have advantages in various features. Yet, innovation in rotary broaching tools is still alive and should be considered for various forms including small involute splines and serrations. Rotary […]

The Factor of Safety as a Statistical Design Variable

This month, we’ll explore the factor of safety as a statistical design variable in a Strength vs. Demand model and how to use a reliability-based service factor to best benefit you and your business.

Classic Factors of safety – sometimes called service factors According to NEMA, a Motor Service Factor (SF) is the percentage of overload the motor can handle for short periods when operating normally within the correct voltage tolerances. It is well known in AC motors that a startup power spike is around 300% of rated load. […]

(LPC) furnaces employ strategically positioned jets, and atmosphere furnaces must use the proper fan

When it comes to carburizing or protecting parts subjected to an atmosphere, fan- and gas-injection methods become the critical factor. Vacuum furnaces have air removed by vacuum pumps, but by carburizing at low-pressure carburizing (LPC) pressures, fans are ineffective because too few gas molecules to circulate. Therefore, LPC with acetylene must be introduced in a […]

Trend Talks: Anna Claire Conrad

Here, you’ll find suggestions and tips to help you regulate daily operations at your company that can have a wide-reaching, beneficial ripple effect.

This is my first “real world” job after graduating from college, and in the six months I’ve been here, I’ve learned a lot more about the gear manufacturing industry than I ever thought I’d need to know. And while knowing the difference between hobbing and milling is important, as the associate editor, my job requires […]
