When creating a transport system using timing belts, it is necessary to create the corresponding pulleys with a high level of precision which in many cases cannot be guaranteed using standard off-the-shelf pulleys.
In order to achieve a high standard of quality and ensure that the machining is aligned with the teeth, our production process involves the initial phases being carried out using CNC machining centres and lathes, before then performing the toothing as the last operation, taking advantage of the existing machining for placement.
When the number of pulleys is fairly large, we can create a mould to make aluminium castings in order to ensure excellent technical results combined with the best price-quality ratio.
As we already have various rough castings available in diameters up to 800 mm, we recommend sending us drawings of the pulley to be created so that we can check if we already have a suitable rough casting geometry in stock.
timing belts for belts are made with certified generators both with normal and zero backlash, and are available in the following pitches: AT – T – XL – L – H -XH – HTD – RPP – ATP.
The most common system to hold the timing belt on the pulley is to use flanges which are pressed on, or alternatively threaded holes can be created on the pulley before screwing on the flanges.
The first solution is the cheapest but offers less of a guarantee of long-term holding, while the second solution is the most reliable, and also allows thicker flanges to be used.
When using flanges, residue of the transported product can be deposited in the area between the belt and the flange; the most cost-effective solution to solve this problem is to use a belt with a trapezoidal profile, which when combined with the use of pulleys with a central throat, allows the system to be self-guided.
If the pitch diameters are small, the pulley can be made in two parts, placing a spoked disc in the middle which can keep the belt guided with a central channel.
Usually off-the-shelf plates are used to lock the ends of the open timing belt, but when the design requires a non-standard geometry we can create toothed plates to drawing specifications in any material and format.
When the application requires only a part to be toothed, it is possible to supply sectors made to drawing specifications in any material, which are subsequently toothed for belt or gear.
As well as timing belts for belts, we are also able to supply gears, as we have generators for metric module toothing (from 0.5 to 6 mm) we can create gear wheels, whole or in sectors, with straight or inclined teeth.
We can create toothed components in most commercially available materials, whether plastics such as POM, PA6, PEEK, TEFLON and NYLON, or metals such as C45 steel, 39NiCrMo4, BRASS, BRONZE, ALUMINIUM, STEEL, STAINLESS STEEL etc.; we use only certified materials in order to guarantee the origin of the parts made to drawing specifications which we supply.
As well as being able to count on many types of different metals, we can also combine specific treatments such as:
ANODISATION, BLUING, GALVANISATION, NICKEL PLATING, HARD ANODIC OXIDISATION, GOLD HARD ANODISATION (GHA) etc.
