Induction Heating: A Guide to the Process and Its Benefits

Surface distress in industrial applications is a phenomenon associated with poor lubrication that generates high local friction and stress.

Induction hardening is being increasingly used within the gear industry. However, before looking at the advantages of the method, it is helpful to review the basics of the technology. The phenomenon of induction heating begins by passing an alternating current through a coil in order to generate a magnetic field. The strength of the field […]

An Algorithm for Robust Gear Modifications Design

Algorithms present all possible solutions to help designers decide what is the best gear modification.

The design of gear modifications is one of the key tasks for high performance gears, where high performance may be defined as, a maximized torque capacity, minimized vibration level, highest scuffing resistance or lowest wear risk. Gear modifications, or the gear micro geometry, are assessed in the tooth contact analysis TCA where the true gear […]

Understanding and Preventing Surface Distress

Surface distress in industrial applications is a phenomenon associated with poor lubrication and other mechanical aspects that generate high local friction and stress.

In many industrial applications that have lubricated rolling/sliding contacts such as rolling bearings, power density has steadily increased over time due to the need for greater efficiency, reduction of weight and costs (i.e., downsizing). Alongside this has been an increased severity in working conditions, such as heavier loads in combination with higher temperatures, thinner oil […]

91 percent of survey respondents dunk quench in oil. So, why does LPC continue to be conducted in graphite lined furnaces?

Twelve years ago I commissioned a study to identify trends in the heat treating industry where part of that survey involved three processes: traditional endo carburizing, low pressure carburizing [LPC] and quenching; high pressure gas quenching [HPGQ], oil and salt. Of the 27% who responded to the survey, a very high return rate, 91% of […]

Q&A with Stephen P. Radzevich Ph.D.

Professor of Mechanical Engineering and Manufacturing Engineering

You have written a book titled, Theory of Gearing: Kinematics, Geometry, and Synthesis. What does the book discuss? This book systematically presents and develops a scientific theory of gearing, specifically for those involved in gear design, analysis, and manufacture. I begin with a few simple postulates that form the foundation of the theory of gearing. […]

Terry McDonald: Site Safety

Establish written hazardous energy control programs so employees understand and follow established procedures.

Machine-related injuries or fatalities are at the highest during maintenance, service, repairs or adjustments. One simple way to avoid accidents or deaths is to incorporate lockout or tagout procedures in the shop. According to the Department of Health and Human Services, and the National Institute for Occupational Safety and Health, 185 fatalities related to installation, […]

When considering the gear mesh, backlash is high on the list of misunderstandings

Among the many considerations when considering the gear mesh, backlash is high on the list of misunderstandings. Backlash has a cyclically fluctuating value between minimum and maximum values. If there is zero backlash, then there is no room for the ingress of lubricant and temperature expansion. Backlash is a function of tooth thickness tolerances, run-out, […]
