Moving in the Right Direction

June 1, 2017

Over the past several months, members of our staff have traveled quite a bit, and we've had a lot of opportunities to gauge their confidence. And while nobody is overwhelmingly enthusiastic - nobody has told us this is their best year ever - almost everyone seems at least content with the stability that slow and steady growth provides.

Guide to V-Belt Selection and Replacement

June 1, 2017

V-belts look like relatively benign and simple pieces of equipment. They're basically a glorified rubber band, right? Need a replacement? Just measure the top width and circumference, find another belt with the same dimensions, and slap it on the drive. There's only one problem: that approach is about as wrong as you can get.

How to Select a DC Motor: Coreless and Iron Core Brushed DC Motors

June 1, 2017

DC motors possess linear relationships that allow for very predictable operation. For instance, if enough voltage is applied across the terminals of a DC motor, the output shaft will spin at a rate proportional to that applied voltage. You can take the ratio of the applied voltage over the rated voltage and multiply that number by the no load speed and get the running speed.

Determination of Load Distributions on Double Helical-Geared Planetary Gearboxes

June 1, 2017

Standardized calculation methods such as ISO 6336 and DIN 3990 already exist to determine the load distributions on gears inside a planetary gearbox, but by their very universal nature, these methods offer varying results depending on the gearbox design. Double helical gears, in particular, can benefit from more specific, complex algorithms to reach a maximum level of efficiency. Double helical gears interact with the rest of the gearbox differently than helical or spur gears, and thus benefit from different analytical models outside the standardized methods. The present research project describes the algorithm to determine the load distribution of planetary gearboxes with double helical gears.
