This report derives the equation for relative elastohydrodynamic lubrication (EHL) film thickness. Mineral (MIN), polyalphaolefin (PAO), and polyalkylene glycol (PAG) lubricants with viscosity grades of ISO 320, 150, and 32 are analyzed.

More energy efficiency, higher performance and better controllability are the main reasons why more electric drive systems are being operated with frequency converters. However, these devices can cause high-frequency, asymmetrical interference currents, which, as a current passage through the output and fan-side bearings, can cause damage and premature failure.

Current-compensated CoolBlue toroidal cores made of Magnetec’s nanocrystalline material Nanoperm have proven to be effective protection against such conducted interference and its consequences. In addition, the Nanoperm Line Absorbers NaLA can also be used to significantly suppress symmetrical interference currents.

From manufacturing to maritime, the quest for sustainable solutions has given rise to the development of environmentally friendly lubricants. Among these, Environmentally Considerate Lubricants (ECL) and Environmentally Acceptable Lubricants (EALs) have gained prominence for their positive impact on both equipment performance and the planet. Let’s delve into the differences and advantages of these lubricant classifications.

Portescap introduces the new R22T gearhead, the latest addition to its existing 22 mm gearbox portfolio. As a mid-torque gearhead, the R22T fills the gap between our light-torque R22 and high-torque R22HT gearheads. It is also fully compatible with Portescap’s brush DC and brushless DC slotless motors.

Rolling bearing calculations are usually based on the assumption of ideal nominal geometries. However, actual components and assemblies are always subject to statically distributed geometric deviations resulting from the manufacturing and assembly processes. This leads to changes in the internal geometric conditions which have an effect on bearing characteristics such as the service life. The FVA-Workbench makes it possible for users to consider these geometric deviations in bearing calculations for more reliable results.

Motion + Power Technology (MPT) show brings together the gear and power transmission industries for a unique balance of education, new technologies and networking opportunities. The show takes place October 17-19,2023 in Detroit. 

The Power Transmission Distributors Association (PTDA) welcomes three new distributors to its membership including Gordon Russell, MROSupply.com and Grainger.

The loaded tooth contact analysis (LTCA) is crucial in understanding the deformation of gears and its impact on various factors such as noise generation, contact patterns, contact shocks, and torque variations. With the contact analysis feature in KISSsoft, users can calculate tooth contact under specific torque and speed levels, thereby assessing the performance of gears and gearboxes.

JW Winco has expanded its product range with two compact and robust angular gearboxes that translate rotational movements by 90 degrees and transmit high torques with or without a gear ratio. They are suitable for applications such as handling systems, packaging machines, and conveyor technology.

Voith Turbo North America has broken ground on a $5 million expansion of its workshop in York, Pa. The expansion will increase the Group Division’s American manufacturing capabilities.
