For the purpose of positive driven interlaced wire belts, metals are produced on a plastic traction wheel. These wheels consist of grooves in which the wire of the interlaced mesh belts fall. The belts are, depending on the application, provided of a bore, key way and tapped hole.
The drive wheels for the interlaced wire belts are produced by ourselves. This enables us to realize nearly all technical versions of the sprocketss. The most important parameters in there are, teeth (longitunal pitch circle), width, types of material, bore, whether or not a key way or whether or not a tapped hole (with set screw). There are certain recommendations to be made for these parameters:
- – Amount of teeth (longitunal pitch circle); recommended 8 up to 70 (take a look at features)
- – Width; in conformity with customer specifications, at least 20 mm
- – Materials: POM, PA6G, 1.4305, 1.4404, 1.0503
- – Bore: in conformity with customer specifications. Round bore is preferred
- – Key way: always (idle rollers could possible do without)
- – Tapped hole; to prevent the axle of getting damaged, it is preferred to secure on the key way and not on the axle.
The GR drive wheels, including the positively propelled principle of interlaced wire belts are characterised by: Drive on the basis of sprockets; no chance on belt slip
- – The advice is to take wheels with an as small as possible longitunal pitch circle (but at least 8 teeth)
- – The advice is to make the sprockets as large as the opening would allow
- – The advice is to take sprockets at every second opening
- – A large turned around angle of the belt, with respect to the sprockets (>180°), is being preferred
When a Type 1600: GR-SK or GR-ZK belt is used, these sprockets are used as well. The applications for this belt are thus similar.
- – Conveyor belt in installations for baking, frying, grilling, etc.
- – Conveyor belts in installations either used for sprinkling or to drape
- – Take-over sets
