Planetary gearheads are high-precision, motion-control devices that generate substantial torque for their size, have high torsional stiffness, and low backlash — making them suitable for wide-ranging tasks. Choosing the right gearhead and accurately sizing it is critical to long and reliable life. As a starting point, designers can approximate required gearhead size from: Tr = [...]
10 tips for using couplings in your application Choosing the correct coupling for the task at hand is no easy task. It means asking the right questions before specifying a particular style. Choices abound, and more than one coupling type may be suitable for any given application. Here we share with you expert tips and [...]
Our sales engineers Peter Moody (South East) and David Wood (Internal Sales) jetted off to Germany to refresh their product knowledge at Graessner. It was an intense two-day workshop where they met up with Jens Kehrer, Product manager at Graessner and also met with their product and marketing team. Both of them have come back [...]
Drive Lines Technologies, the specialist provider of power transmission solutions, now offers a complete linear drive solution incorporating rack and pinion mechanisms that complement the MS-Graessner ranges of precision servo gearboxes, including KS-TwinGear, DynaGear, DynaGear DG and DynaGear PL systems. These comprehensive solutions include low-backlash precision gearboxes, shrink-fit direct shaft mounted pinion gears and precision [...]
In a corner of northwest England’s Sellafield – one of the most complex and dense nuclear sites in the world – a team of engineers is proving just that. After years of collaboration, designs and painstaking rehearsals, a Bechtel-Cavendish Nuclear joint venture, under the aegis of Sellafield Ltd, has achieved a major milestone. The Pile [...]
A new size, the P-65, has been added to the Graessner PowerGear P range of bevel gearboxes available from Bedford-based Drive Lines. Being 65mm cubed in size it is expected to prove very popular in a wide range of applications, such as for use with screw jacks to create vertical lifting and lowering mechanisms. With [...]
It is probably a natural reaction to assume that backlash is a bad thing which needs to be designed out of every engineered system. The reality isn’t so simple, as Ian Carr, Managing Director of Drive Line Technologies, explains: there are times when backlash is unacceptable; other times when it does not really have any [...]
Meeting the needs of demanding servo applications in areas such as packaging, materials handling, machine tools and robotics, as well as general automation, Drive Lines Technologies includes a precision worm gearbox in their Servoplan range. Promising maintenance-free, long life operation with a highly compact design, the SWG gearhead can be specified with precision of better than [...]
From flood prevention to resource protection, water represents one of today’s biggest ecological challenges. Tilting flumes are increasingly providing engineers with a key tool in the research of hydraulics and sedimentology. The latest products from Armfield offer the greatest levels of versatility, thanks to an automated jacking system supplied by Drives Lines Technologies Ltd. People [...]
