Helical Planetary Gearboxes: Understanding The Tradeoffs

September 11, 2019 By

The choice between helical and spur gears in planetary gearboxes may seem straightforward. Go with helical gears if you want the gearbox to run as smoothly and quietly as possible. Choose spur gears when you need to maximize the gearbox’s torque density or working life under high loads.

These rules of thumb capture most of what you need to know when specifying traditional fixed axis gearboxes. Just size the gearbox properly, and the choice between helical and spur gears will often be obvious for a given set of application requirements. With planetary gearboxes, however, the choice between helical and spur requires some additional thought.

In our latest white paper, we’ll help you understand the differences between helical and spur planetary gearboxes so you can decide which is right for your application.

Improve the Productivity of your Factory Automation Systems with Lightweight Gears and Actuators

May 20, 2015 By

After sliding from its peak more than 25 years ago, U.S. manufacturing appears to be on the way back. Factory automation is a critical element enabling U.S. manufacturing companies to effectively compete in the global marketplace. To maintain this competitive trend, modern robotic and automation systems require higher precision and faster speeds than ever before.

Application Note: Load Testing a Brushless DC Gearmotor and Control System

December 29, 2014 By

When designing a new piece of equipment that uses motors or gearmotors, design engineers must calculate how much motor torque will be needed to drive their application load. If the gearmotor or motor is undersized and too small, the product will be underpowered and likely not meet all application requirements. If the gearmotor or motor delivers more power and torque than required, then it adds unnecessary cost, requires more space and can negatively affect the total weight of the equipment.

Learn how to determine the actual load on a brushless DC motor or gearmotor by measuring the amount of current it draws. Step-by-step procedures explain how to compare motor torque calculations vs. real-world performance.

Backlash vs. Stiffness: What is the difference and why you should care. A white paper from Haydon Kerk

March 25, 2010 By

In any partnership, communication is critical to success. When engineers or designers can accurately communicate their goals, their suppliers can provide the best guidance and advice. Like most industries, motion control has its jargon and buzzwords. Some are used interchangeably leading to ambiguity and possible confusion. Backlash and stiffness are both important but have different impact, and those differences deserve attention.

Backlash is a characteristic of a mechanical drive system; clearances among the elements create slop when stationary and dead play during reversals. Stiffness is a property of a mechanism or component. Stiffness is simply the resistance to deformation or deflection when loaded.
