This Customized Gearbox Saved Both Time and Money

Many machine designers look to use standard components with the idea of saving time and money. But quite often a customized solution can do a better job of achieving both. We had a customer using a larger than necessary helical bevel speed reducer because of the requirement of a large output bore. They needed to drive a cooling drum in a plastic extrusion application. In addition to the driving torque, they had to feed a water line through the drum shaft journal to circulate water for the cooling process. To accommodate the water line a larger [...]

Quick Connection Improves Efficiency

Short-run printing and automated machining require quick tool changes to achieve customized production in an efficient manner. Two different applications use the same design concept to solve this problem. In the first application, a manufacturer of printing presses was looking for a quick-connect system to speed up cylinder changes. With short-run printing becoming the norm, print cylinder changeover was eating up a lot of production time. In the past, a transfer gear was installed on the cylinder shaft journal. However, because of a gear error, some motion variations were created. The new quick-connect system design [...]

Reciprocating Motion Without Servos

Shaft-phasing gearboxes can be used for more than just registration and timing applications. In this example, the customer discovered a unique application for shaft-phasing gearboxes, using their dual input gear drive design to achieve reciprocating motion, beyond traditional registration and timing applications. Shaft-phasing gearboxes go by a variety of names - including speed correction drives and timing differentials. The differential moniker came from the original bevel gear designs, with side spider gears, that could be rotated with or against the direction of the main drive gears. This had the effect of speeding up or slowing [...]
