Rack and pinion drives: A new look at an old technology

December 15, 2021 By Miles Budimir Leave a Comment

rack and pinion

Comparing rack and pinion drives with other linear drives such as belts and ball screws shows that sometimes simplicity can be the ultimate sophistication. YYC North America These days engineers have quite a few options for actuation in a linear motion system. From various screw drives to linear motors to hydraulic systems, each comes with […]

How to account for rack and pinion inertia during system design

October 21, 2021 By Danielle Collins Leave a Comment

Rack and pinion systems

Rack and pinion drives are often used in applications that require stroke lengths beyond the practical limits of ball screws and thrust forces that exceed the capabilities of belt drives. And in some applications, rack and pinion systems can also provide lower total inertia than a suitable ball screw or belt drive alternative, which can […]

What are some linear motion options for moving multiple loads independently?

July 7, 2021 By Danielle Collins Leave a Comment

move multiple loads independently

From a mechanical standpoint, one of the more challenging applications in linear motion has traditionally been to move two or more loads independently, as is required in some handling, transport, and inspection applications. While using multiple linear systems, or preassembled actuators, is a simple solution mechanically, this option typically requires a significant amount of space […]

What’s the difference between module and diametral pitch for rack and pinion drives?

May 14, 2021 By Danielle Collins Leave a Comment

Gear sizes are typically specified by one of two designations: module or diametral pitch. While both specifications define the size of the gear teeth, module and diametral pitch are calculated differently, with module (sometimes referred to as metric pitch) being the metric sizing standard and diametrical pitch being the Imperial (inch) sizing method. Standard modules for […]

Mapping tool optimizes gear rack assembly to maximize positioning accuracy

January 22, 2021 By Miles Budimir Leave a Comment

gear rack

The positioning accuracy of a rack & pinion drive is dependent on the cumulative pitch error inherent in each gear rack used. For long travel lengths, this cumulative pitch error can add up quickly and dramatically affect the positioning accuracy of the axis. ATLANTA now offers “digital” gear racks and a smartphone app that when […]

The top 10 linear motion articles of 2020

December 28, 2020 By Danielle Collins Leave a Comment

linear motion articles

Suffice it to say, pretty much everything about 2020 has been out of the ordinary, and our recap of the top linear motion articles for this year is no exception. For the first time in recent history, only one (1!) of the top 10 articles is about ball or lead screw technologies — a topic that usually […]

How to size a rack-and-pinion system for a precision motion axis

November 20, 2019 By Lisa Eitel Leave a Comment

In a previous motion-sizing article, we reviewed how to properly specify a ballscrew-driven motion axis. Here we review how engineering teams can use a similar approach for sizing rack-and-pinion-based servomotor-driven axes on the same five-axis gantry. We’ll use manufacturer software to work through the application. By Sixto Moralez • Regional motion engineer | Yaskawa America […]

Güdel 7th axis on bakery machine Workhorse Automation design for baking showing loaf pans

In the U.S., about 50 million people a day eat at fast-food restaurants — and about 60,000 of those establishments sell hamburgers. That requires epic volumes of fresh buns every day … and only commercial bakeries with automated operations can output sufficient production volumes. Workhorse Automation Inc. (based in Oxford, Pa.) supplies machines to this […]

How to size a rack and pinion drive

January 2, 2019 By Danielle Collins 2 Comments

rack and pinion drive

In linear motion applications, ball screws are widely recognized for their ability to provide high thrust forces, while linear motors are gaining market share in high-speed applications, and belt drives continue to maintain their reputation as the best solution for long travel lengths. But rack and pinion drives are the often-overlooked workhorses behind gantry and […]
