An introduction to stepper motors and stepper drivers
Bill Schweber of Mouser Electronics provides an introduction to stepper motors and drivers that will help machine builders and OEMs specify the right products to suit their applications.
Prevention of white etching cracks in rolling bearings
The formation of white etching cracks (WEC) in rolling bearings can lead to their premature failure. However, a number of innovative approaches have been developed that significantly reduce the risk of WEC, says Dr Steve Lacey, engineering manager at Schaeffler UK.
Machine guarding requirements for robot cells
This article from Axelent discusses the important issue of guarding for robot cells when the guard is to be positioned within the motion range of the robot.
Safety interlocking in the waste and recycling industry
A metal recycling firm was recently fined £35,000 by the HSE after a worker’s hands were severed while cutting metal strips on an industrial baler. Industrial balers are used to compress recyclable material into stackable, manageable pieces before they are sent for reprocessing. This type of machinery should be extensively guarded and interlocked to ensure operators can only come into contact with the machine when the power has been isolated.
Solenoid valves – one for every occasion
Solenoid valves perform an essential task in the control of fluids and gases and the basic design has been refined over the years to allow them to be utilised in a wider range of applications. Modern fluid control systems present a number of challenges that require the correct design of solenoid to achieve a reliable and efficient control process. Kelly Booth, solenoid valve specialist at Bürkert UK, looks at the different valve types and their suitability to various applications.
Specifying standard, modified or customised worm gear sets
Darren Reynolds, the Gears Product Manager at R.A. Rodriguez (U.K.) Limited, outlines the most important factors to consider when specifying either standard or custom worm gears sets for any type of machinery.
Gaining production efficiencies in food and beverage processing
By selecting, maintaining and monitoring critical components and inside rotating plant and machines such as gearboxes, electric motors, pumps and fans, food and beverage processing companies can improve their plant efficiencies, eliminate production downtime and increase the operating life and reliability of plant equipment, says Dr Steve Lacey, Engineering Manager at Schaeffler UK.
Powering cathodic protection
Often dubbed the inconspicuous killer, rust costs the global economy $2.2 trillion dollars every year. It accounts for anywhere between 3.5 to 4.5 per cent of gross domestic product (GDP) and is responsible for the structural failure of steel frames around the world. From bridges and cars, transcontinental and marine pipelines, to industrial machinery, tools and parts, rust contributes significantly to plant downtime the world over.
