by Tony Kliber, Lead Design Engineer, Nexen Group Reviewing the basics about the most popular linear positioning devices will help users properly specify them in their applications. Linear drive systems have been used for thousands of years, as far back as the ancient Egyptians who used tree trunks to move heavy blocks of stones, providing […]
Rack + pinion driven
A selection guide for linear systems
Gone are the days when machine designers and builders had to choose between constructing their own linear system from scratch or settling for a limited range of pre-assembled systems that, in most cases, were an imperfect fit for their application. Manufacturers today offer systems based on a range of drive mechanisms—ball screws, belts, rack and pinions, linear motors, […]
Three factors critical to servo motor sizing for linear motion systems
Selecting the right servo motor for a linear motion system is a complex task, beginning with initial assumptions and component selections, which must be checked through a series of calculations and, in most cases, repeated over several iterations until a suitable combination of motor and mechanics is found. Most motor manufacturers offer online sizing tools that make […]
Linear Stage Features New Drive Mechanism
Bell-Everman’s new ServoSpline™ positioning stage offers a unique drive mechanism that provides backlash-free motion and simplified control. ServoSpline is an extension of a classic rack-and-pinion design that provides simple motion commands and positions the stage in the x- and y-axis by independently driving the two splines. It provides engineers with a reliable stage that is […]
How to make your linear motion technology easy to maintain
Adding linear motion to articulated robots adds flexibility and extends the work envelope of your system. The 7th axis tracks that enable this linear motion all provide the same functionality but differ in one significant design feature: the antifriction bearing system used to support and guide the tracks. Watch this video to learn how to select the […]
