1 Homogeneous Geometry Calculation of Arbitrary Tooth Shapes: Mathematical Approach and Practical Applications (February 2016)

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.

2 Clutches: Declassified (March 2016)

In the world of PT components, the clutch gets absolutely no recognition whatsoever. There are entire magazines dedicated to gears, bearings and motors, but clutches get very little press outside of the automotive industry.

3 Load Ratings & Bearing Life (March 2016)

Power Transmission Engineering is collaborating with the Bearing Specialists Association (BSA) on a special section within the magazine.

12 Proper Handling of Bearings (September 2016)

Rolling-element bearings are high-precision components that need to be stored and handled carefully to perform as designed. Proper storage and handling of a bearing before, during and after installation is important because once debris enters a bearing, it reduces the life.

21 Engineering Showcase 2017 (March 2017)

One of our goals at Power Transmission Engineering is to help you understand, identify and select the best technology for your mechanical power transmission or motion control applications. With every project, you have to decide which components to use, and which suppliers, based on functionality, quality and price. We aim to help you make those decisions informed by providing the latest information on current technology, especially when it comes to mechanical components.

26 Not All Thin-Section Bearings Are Created Equal (February 2011)

American Bearing Manufacturers Association (ABMA) Standard 9 and ISO 281 give equations for calculating the basic dynamic radial load rating for ball bearings. These equations are based on a number of assumptions, many of which are not valid for thin-section bearings. (Thin-section bearings are described in ABMA standard 26.2.) Nevertheless, many thin-section bearing catalogs report load ratings based on these equations. Kaydon has developed a new method for calculating the dynamic radial load rating for thin-section ball bearings. The new method uses the contact stress and the number of stress-cycles-per-revolution to calculate the capacity. The new numbers are based on five years of actual test results. These equations can also be used to calculate the dynamic radial load rating for four-point contact ball bearings, which are not covered in ABMA standard 9 or ISO 281.

27 Airport Baggage Handling: Queue Conveyor Design from a Gearmotor Perspective (February 2011)

The primary driver of an airport baggage handling queue conveyor must be able to operate under increasingly demanding operating conditions, including frequent starting and stopping. The selection of the primary driver of the queue conveyor is dependent on multiple criteria, including dimensional requirements and durability characteristics.

29 Frictionless, Magnetic Gears and Couplings Gain Traction (February 2010)

The Magnetic Gearing and Turbine Corp. (MGT), founded by Australian inventor Andrew French in 2000, manufactures injection molded gears and couplings based entirely on magnetic technology. The repulsive magnetic forces are used to transmit power without losing any energy, and drive shafts rotate completely independently of each other.

37 Evolution of Worm Gear Standards and their Consequences on Load Capacity Calculation Approach (September 2014)

Beginning with a brief summary and update of the latest advances in the calculation methods for worm gears, the author then presents the detailed approach to worm gear geometry found in the revised ISO TR 10828. With that information, and by presenting examples, these new methods are explained, as are their possibilities for addressing the geometrical particularities of worm gears and their impact upon the behavior and load capacity of a gearset under working conditions based on ISO TR 14521 — Methods B and C. The author also highlights the new possibilities offered on that basis for the further evolution of load capacity calculation of a worm gearset based on load and contact pressure distribution.

39 The Efficient Drive System (December 2013)

It's a fact that drive systems wouldn't function properly or efficiently without couplings. They quietly go about their business of transferring motion from one drive element to the next. In the PT market today, couplings have the unique challenge of satisfying a variety of customer needs including tighter tolerances, higher speeds and a more versatile selection process.
