Generally, rack and pinion drives were developed from a planetary gear unit with a gearwheel fitted to the output shaft and the matching gear rack. But the overhung load on the gear unit from the rack and pinion combination is then so high that it actually determines the dimensioning. Gear unit torque availability is normally only in the 40 – 60 % range. Stober and gear rack manufacturer, Atlanta have jointly developed a new...

First engineering school for 20 years gets green light for University of Lincoln (09/07/2010)
Work has begun on the first new engineering school to be created in the UK for more than 20 years. Planners at City of Lincoln Council gave the green light to proposals by the University of Lincoln to build an Engineering Hub at its Brayford Pool campus. The new school will have a temporary presence in Think Tank, the city council’s nearby business innovation centre, while the £7m facility is being built. The first students will enrol on undergraduate and postgraduate...
All-thermoplastic ball screw assemblies from Abssac (07/07/2010)
Abssac is able to offer a complete ball screw and nut assembly manufactured entirely from thermoplastic materials, including polymide (PA) or polyacetal (POM) as a base material. DuPont Vespel is also available for applications requiring maximum strength and durability as well as low friction. The thermoplastic ball screw does not require lubrication and is thus suitable for clean room, anti-magnetic, surgical, aquatic and corrosive environment applications....
Fully sealed drive-side mounted brake for any vertical or gravity loaded axis (07/07/2010)
A safety brake for any vertical or gravity loaded axis, the ROBA topstop, is a new fully sealed, drive side mounted brake from Mayr Power Transmissions. The EN ISO13849 1 compliant, compact and lightweight unit can be easily retrofitted to existing servo systems to prevent uncontrolled vertical movements in a power off or emergency stop situation. ROBA-topstop is available as a single or double circuit brake with either a shaft...

Accumulation chains from Iwis come in several versions (28/06/2010)
Accumulation chains have an enlarged conveying roller every other segment, which transports the conveyed materials and allows the chain to pass underneath queued material without damaging it. Used in feeding applications, automation engineering and to provide gentle transportation of, for example, workpiece carriers, accumulation chains are exceptionally versatile. New Iwis branded accumulation chains include versions with...

Linear ball guide brake imposes no load on the bearing block (28/06/2010)
Sometimes the introduction of a simple device can make a significant difference to the application scope of a product. The LBG brake option from HepcoMotion, which provides a compact and easy method of locking a bearing block in position on its LBG linear ball guide, is a good example. Stainless steel bodied to resist corrosion, the brake is intended for manual locking of a stationary block and can be supplied with a range of brake plates to suit most of the LBG...
Non-contact clutches: a very clean affair (28/06/2010)
Misumi Europa’s rollers and conveyor components product group now includes magnetic clutches that provide non-contact, low-wear, magnetic power transmission for transport devices installed in contaminant-sensitive environments such as clean rooms. Conveyors in clean rooms require transport devices that create as little dust as possible. The TM series magnetic clutches transmit rotary motion via magnetic interaction, so there is no physical contact between clutch...
