Spring applied brake for outdoor applications(22/08/2012)

The new INTORQ BFK471 brake from Lenze Techdrives delivers up to 1,500Nm in a package that is compact, economic and protected to IP66. This is a spring applied design that is normally engaged, and is released by applying a dc voltage.
Mayr extends torque range of its ROBA-contitorque units(20/07/2012)

Mayr’s range of ROBA-contitorque permanent magnet hysteresis clutch/brake units has been expanded with the introduction of the new size 5 unit.
JBJ helps with coupling element sizing and gearbox cooling(18/07/2012)

JBJ Techniques has added two helpful sections to its website covering the sizing of power transmission couplings and selection of gearbox cooling units.
Zero backlash jaw couplings for machine vision systems(06/07/2012)

Ruland offers zero backlash jaw couplings for the demanding requirements of start and stop machine vision systems. The dampening characteristics of Ruland’s jaw couplings reduce settling time and shock loads, making them ideal for these environments. The jaw couplings are a three piece design comprised of two aluminum hubs and an elastomer element called the 'spider'.
Tsubaki introduces new BS/DIN Lambda lube free chain(03/07/2012)

Tsubaki Lambda sintered oil impregnated bushes have been upgraded to the optimum composition of sintered metals. The lubricant specifications and oil impregnation methods have been reviewed and further improved. In addition, heat treatment and overall bush geometry have been improved to secure optimal performance.
High performance gear production machines - without the price premium(21/05/2012)

Hemel Hempstead-based precision component manufacturer, Microprecision is now exclusively distributing a high precision and cost-effective range of CNC gear-production machine tools from South Korean company S&T Dynamics. The range - which includes hobbers, shapers, shavers, deburrers and associated accessories - offers quality levels normally associated with top-of-the-range machines, but without the price premium.
SEW Eurodrive solves tank agitator gearbox problem(15/05/2012)

When a major snack food manufacturer ran into problems with the drive system on one of its large starch reclamation tanks, it turned to SEW Eurodrive to design a fit-and-forget replacement. The food manufacturer had experienced an unacceptable increase in the mean-time to failure rate on the tank’s gearbox, with four failures in a 12 month period.
Shaft coupling provides double role for pond aeration device(03/05/2012)

A challenge Abssac faced recently was to develop a flexible shaft coupling that could be used in the drive assembly of an 'aerator' used to oxygenate water in fish spawning ponds and small lakes. Aeration is especially required in times of hot weather where the oxygen concentration within the water can fall and have a detrimental effect on spawning.
Compact worm gear drives for fixed and portable applications(03/05/2012)

CP Automation is currently distributing Chiaravalli’s failsafe spring-applied motor gearboxes, which are suitable for heavy duty applications such as printing and paper converting, as well as applications like portable lifting equipment when coupled to a battery-operated dc motor.
Powerful and versatile industrial gear units from SEW Eurodrive(16/04/2012)

SEW Eurodrive’s heavy-duty X series range of helical and bevel helical units offers a choice of 23 finely graduated sizes, with torque ratings from 6.8 to 475kNm. This enables a close match of gearbox to application, rather than having to specify one that’s too big because a requirement falls in the middle of two size options.
Supacat and RNLI show new lifeboat launcher(29/03/2012)

The Supacat Launch & Recovery System (L&RS) for the latest class of RNLI lifeboat – the Shannon – has officially been displayed for the first time by the Supacat and RNLI’s joint project teams responsible for its development. The production standard L&RS was demonstrated and inspected by representatives from its 30 key component suppliers as part of a supply chain briefing held at Supacat’s Devon facility.
New textbook information resource for synchronous belt technology(21/03/2012)

Handbook Timing Belts: Principles, Calculations, Applications - a publication originally written and published in German by Raimund Perneder in 2009 - has recently been translated into English with additional content contribution from its co-author, Ian Osborne, the chairman of Transmission Developments. Based on over 60 years of combined professional experience, this hardcover publication runs to 269 pages with 237 illustrations.
Disc couplings for systems demanding high accuracy(06/03/2012)

Ruland offers both single and double (pictured) disc style couplings for systems demanding high accuracy. These couplings have low inertia and are torsionally stiff, making them suitable for precise zero-backlash systems with speeds up to 10,000rpm. Ruland single and double disc couplings are available in both clamp style and set screw style with bore sizes ranging from 3mm to 30mm.
David Brown Gear Systems wins cash to accelerate offshore wind innovation(28/02/2012)

David Brown Gear Systems has been confirmed as the first successful bidder to a government scheme to support manufacturers developing next generation offshore wind technology. The company,based in Huddersfield, has been awarded a £1.2m grant to help develop a gearbox for a 7MW offshore wind turbine. It is the first company to be awarded funding under DECC and the Technology Strategy Board’s Offshore Wind Component Technologies Innovation scheme which is worth around £5m.
Chain offers high performance in wet and corrosive duties(20/01/2012)

There are now four versions of Tsubaki’s BS/DIN European Standard Chain for use in corrosive environments. Each version is designed to outlast standard chains across the widest range of operating environments, including low temperature, sanitary, outdoor, wet and humid atmospheres. With lower operating noise and lube free options there is a chain type in this range that will suit most applications.
