Sheave Alignment: Aim Small, Miss Small
A customer recently called saying his Belt Hog Sheave Alignment Tool was out of calibration. He stated that when he placed the Belt Hog lasers in the sheave grooves, they showed a slight amount of misalignment. However, when he rotated the lasers 180 degrees to check, there was a variance of 3mm (0.118”). While this…
Read MoreBelt Drive Basics
All over the world belts provide power transmission in transportation, industrial and commercial machines. Belt drives for power transmission are classified as frictional drives. The belt transmits power by contacting the sides of the drive and driven sheaves. Belts are available in several styles: Flat belts, v-belts, Synchronous (timing) belts and Multi-ribbed belts. While belts…

Read MoreV-Belt Alignment of a Variable Pitch Sheave to a Fixed Pitch Sheave
Variable pitch sheaves are used frequently in air handlers. They allow the design engineer to increase or decrease the speed of the driven machine. In doing so, they allow for: Changes in amp draw of the motor, to maximize efficiency, Increase or decrease static pressure and air flow. Normally, the design engineer will specify the…
Read MoreA New Twist on Belt Alignment?
In our quest to realign America, we’re always on the lookout for intriguing applications. Sometimes they pop up in odd places. My buddy Steve Matthews with PdM Solutions spotted this situation while in the field (literally!). This has to be a maintenance headache–there were plenty of belts laying around. How would you tackle this? We…
