Reli-a-Flex Shaft Couplings offers long life, low kinematic error
Reliance Mechatronics launched a flexible shaft coupling that offers high torsional stiffness, low bearing load, long service life and low kinematic error. The Reli-a-Flex coupling achieves high torsional stiffness by placing the beams radially around the coupling. Unlike other coupling with spiral pattern beams, the radial beams support the drive loads in compression. The center […]
PWM Speed Controls Drive Permanent Magnet DC Gearmotors and Motors up to 1/3 HP
12 and 24 Volt PWM Speed Controls from Bodine Electric Company provide simple and reliable speed control for low-voltage 12 or 24V permanent magnet DC (PMDC) gearmotors and motors (up to 1/3 HP / 250 Watts). The controls utilize pulse width modulation (PWM) technology to insure quiet operation, low operating temperature and optimal brush life. […]
How to size clutches and brakes to a design’s motor: An engineer’s guide
Updated May 2019. || Brakes and clutches are a mainstay in motion designs that need to stop, hold or index loads. Especially over the last five years, a technology trend toward application-specific designs has quickened as several industries are pushing the performance envelope of stock components. First step: Pick between clutches and brakes Brakes are used […]
Design engineering guide to selecting compression springs
Updated July 2018 by Lisa Eitel || Several parameters dictate the most suitable helical compression-spring selection for a given application. The OD of a spring expands under compression. Consider this if the spring goes into a tube or a bore during assembly. Also remember that the OD of a spring is subject to manufacturing tolerances, just […]
How to size and select ballcrews: An engineer’s guide
When specifying a ball screw, understanding the application criteria that the component needs to satisfy is essential. There are several factors to consider and each one plays a role in the decision-making process. One approach is to think of the acronym LOSTPED to help evaluate the application. LOSTPED stands for: Load – including the mass being […]
How to size and select gearboxes: A Motion Engineer’s Guide
Updated May 2016. || Application-tailored and custom gearboxes are increasingly common, mainly because they’re easier than ever to manufacture to specification. That’s not to say that the design work isn’t challenging. However, modern manufacturing lets some suppliers make gearboxes and components to meet specific application requirements. New supplier approaches to giving engineering support as well […]
How to select a lead screw: A design engineer’s guide
Lead screws use the helix angle of the thread to convert rotary motion to linear motion. The performance of a lead screw depends on the coefficient of friction between the nut and the screw, which in turn depends on the material used for the nut and screw. Here’s an overview of the most important factors […]
How to Select Retaining Rings: An Engineer’s Guide
When selecting retaining rings for an application, there are a number of factors that determine the right decision. The first question to ask is what kind of assembly does the application require; is it a housing assembly or shaft assembly? Next, determine the main critical dimensions. These include the housing or shaft diameter, groove diameter, […]
