1 Thermal Growth Issues and Solutions for Shaft Couplings (August 2018)

Many refineries and chemical plants are built with large pieces of rotating equipment in an outdoor setting exposed to the elements. The author has been researching thermal growth issues for decades across North America.

2 Thermal Analysis and Optimization of Gearboxes by Simulation (December 2018)

With the increasing mechanical power capacity of gearboxes, the thermal power limit tends to become the limiting factor. To achieve a balanced system, the gear unit needs extra cooling. Using a fan that is mounted to a fast rotating shaft is a common solution. For this solution an optimal design is investigated.

3 The Fundamentals of Specifying and Selecting Gear Drives (December 2012)

Gear drives deliver power to industrial equipment such as bulk material conveyors, mixers, pumps and paper mills. The reliability that translates into greater uptime and profitability begins by specifying and selecting the proper drives for these critical applications.

4 The Importance of Thermal Protection for Torque Motors (August 2015)

When talking about high-end machining or manufacturing applications that include direct-drive technology, one of the key advantages of utilizing this particular transmission method is its endurance. Because of the very nature of direct-drive motors they are able to operate at peak performance levels indefinitely — without any kind of wear or aging — as long as the motor isn’t pushed past its capacity. Unfortunately, because this isn’t a perfect world, unexpected things can happen which can cause the motor to overheat. Whether the heat source is due to a parameter being input incorrectly, or an unexpected external force causing more resistance than expected — it is important to have certain forms of thermal protection in place. Since torque motors are built in such a way that they cannot be repaired and yet maintain their efficiency, it is vital to prevent any overheating — thus precluding the need to purchase a new one.
