DualVee Motion Technology linear guidance technology is now more flexible and more cost-effective.
DualVee Motion Technology - DMT - has been successfully employed in industrial linear guidance applications for over 30 years.
As an integral part of the HepcoMotion product programme, it has proved a popular choice for anti-friction guidance mechanisms, typically in pick and place units and packaging machinery that do not require the ultra-high precision offered by the HepcoMotion GV3 System.
New options will benefit light-duty applications in clean rooms through to rugged transport systems working in hostile environments.
This linear guidance technology is now more flexible and more cost-effective.
As before, the system is built-up from three basic components - tracks, guide wheels and bushings - all of which can be individually supplied to give the user maximum design flexibility and overall cost-effectiveness.
Several new wheel options have been introduced that save time and therefore cost.
New integral bushed wheels, for example, eliminate the need for inserting a separate bush into the wheel before assembly - this development reduces assembly time and component cost.
For low-load, cost-sensitive applications the choice now includes new polymer over-moulded wheels.
These are complemented by the option of crown polymer over-moulded rollers that can run on flat tracks.
The range has also released new lower-cost drilled track and Pristinox processed stainless steel hardened track for applications calling for enhanced corrosion resistance.
MinVee is a low-cost miniature linear guidance system using polymer or steel wheels and the smallest double-edged track.
Wheel capacities across the entire range have been increased by up to 40% in many cases.
This has been achieved through improvements to the wheel's internal bearing design and higher manufacturing tolerances.
All this is available at no extra cost to the customer.
An extended range of wheel cover and lubricator assemblies for integral bushed wheels is also available to extend system life.
DMT is based on a double-row angular contact bearing arrangement.
In common with HepcoMotion standard vee technology, DualVee uses opposing concentric and eccentric bushings that provide a simple but effective means of adjustment for free play and clearance between the track and guide wheels.
The rolling contact between wheel and track provides a constant self-cleaning action.
Butt joining of the track is easily accomplished with DualVee enabling virtually any stroke length to be achieved.
The single-edged tracks can be supplied in standard or custom lengths up to 6m if required, pre-drilled to suit individual design requirements.
In comparison with round or square rail recirculating ball guides, DualVee is 50% quieter and is also significantly cheaper to install, as no ground surfaces are required.
