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.
Getting the most from heavy duty brakes
Heavy duty braking system designs are as diverse as the different industries in which they are employed. From marine and mining to metal working and paper processing, systems are required to perform static, dynamic and emergency braking with precise controlled force. Quality is of the utmost importance in these products as the cost of a short service life can often be very high for the end-user. However, as with all things mechanical, it is possible to improve the reliability and life span of all braking designs with good specification, correct installation and correct maintenance procedures. Steve Powell, Product Manager at Twiflex offers some advice on installation and maintenance to optimise the performance and service life of these very important systems.
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.
Wireless standard harmonisation creates a new problem
As more and more wireless devices come to the market, concerns have emerged within the standards body responsible for managing the radio spectrum allocation and wireless device conformance that more guidance is needed to help ensure spectrum sharing. Tony Ingham of Sensor Technology Ltd reviews the situation.
Changes in the network security landscape
Until a few years ago network security focused on enterprise systems and relied on firewalls to prevent viruses from arriving electronically. Now there is increasing realisation that the production control systems need to be protected too, and that viruses can be uploaded by many means. Industries as diverse as manufacturing, processing, refining, power generation, and food and drink processing are all considering ways to improve the security of their plant and control systems. John Browett of CLPA (CC-Link Partners Association) considers the current position and looks at how to mitigate potential threats.
Predictive maintenance of rail traction motors: depot-based CM
A series of studies have shown that depot-based condition monitoring of railway traction motors using underfloor wheel lathes can be implemented at a fraction of the cost of Remote Condition Monitoring, says Dr Steve Lacey, Engineering Manager at Schaeffler UK.
PI technologies enable innovation for Industry 4.0
In the Industry 4.0, Internet of Things and Big Data environment, industrial communication is of central importance. The close networking of automation components, machines, systems, and IT systems needed for this, including across locations or even between different companies, is only possible with standardised and integrated communication. In recent years, Profibus & Profinet International (PI) has brought about numerous developments that meet these requirements.
