Engineering Smart

Our theme for 2016 is “Engineering Smart.” Our goal as a publication is to help you engineer better systems, taking advantage of the latest in technology to create mechanical systems that last longer, save energy, cost less and increase performance. The way we do that is by bringing you the best information possible on the design and engineering of gears, gear drives, bearings, motors, couplings and related power transmission components and systems.

Homogeneous Geometry Calculation of Arbitrary Tooth Shapes: Mathematical Approach and Practical Applications

This paper provides a mathematical framework and its implementation for calculating the tooth geometry of arbitrary gear types, based on the basic law of gear kinematics. The rack or gear geometry can be generated in two different ways: by calculating the conjugate geometry and the line of contact of a gear to the given geometric shape of a known geometry (e.g., a cutting hob), or by prescribing the surface of action of two gears in contact and calculating the correspondent flank shapes.

Mix and Match Mechatronics

Mechatronics simplifies traditional engineering concepts across most industrial segments. By combining mechanical, electrical and computer technology into a single, integrated solution, products become systems that are more efficient, reduce operator error and cost less to manufacture.

Two-stage Helical Bevel Gearing

Gearing is an essential component in conveyors. The material handling industry appears divided between those who favor high-end three-stage helical bevel gearboxes and those who rely on less expensive worm gearing. But there’s an often over-looked alternative, the two-stage helical bevel gearbox.

Reducing Food Processing Plant Energy Costs

U.S. manufacturers, such as food processors, face an unprecedented competitive environment and must look for ways to be profitable without negatively affecting the quality of finished products.

Motor Management Best Practices Part 3

This three-part series on motor management best practices focuses on the importance of instituting a motor management plan as a necessity in effectively administering the electric motors in a facility. The goal of a motor management plan is to take advantage of opportunities for energy savings and increased productivity using energy efficient, reliable motors such as NEMA Premium efficiency motors, herein referred to as “premium efficiency” motors.

Gyroscopes in Spaaaace!

Moving around in open space is a cautious endeavor. Without the luxury of gravity, the slightest push can send you twirling in circles or, worse, tumbling off into the unknown. Every motion must be thought out and deliberate, all the more so because our bodies take that luxury into account.
