Drive belt pulleys - Import export

Davall Gears manufacture all forms of gearing, both metric and imperial [inch], and are a specialist for spiroid [Spiradrive] face worm and wheel drives.

Hot Vulcanized Drive Pulley: The pulley that drives the belt. Prevents abrasion. Coated with rubber to enable the pulley to grip the body of the pipe tightly. With detachable shaft and is connected to the pulley pipe by a clamp system.

Idler pulley with pin made of stainless steel. The embossing ensures a smooth and steady drive of the conveyor belt.

The high-performance sewing machine from STATEC BINDER stands for precise and reliable bag sealing of woven PP, paper or PE bags. Two different variants can be used for sewing the bags. On the one hand there is the straight-line bag infeed, in which the bag is fed to the sewing head by means of a belt drive and then sewn at the upper end. The second variant is the bag edge folding, in which the bag is folded at the upper end when it is pulled in and then sewn. In order to change from one system to the other, it is only necessary to replace a simple device. The bag to be sewn is fed to the sewing machine via one of the two variants mentioned above. Depending on the sewing speed and performance, the stitch length is between 7 and 12 mm. A cutter at the end cuts the thread. The sewing head is driven by a motor with frequency converter. A big advantage over the drive via belt pulleys is a more precise adjustment of the speed.

Knocker rolls are used on the cleat belt in order to knock off adhering material. The Knocker roll is fitted in the inner belt near the drive pulley. Area of use cleat belts and badly damaged belts Knocker rolls are used when it is not possible to use conveyor cleaning brushes. They can also be used as combination together with a conveyor cleaning brush.

ERF-CAT double suction centrifugal cell fans are produced in different sizes between 1.000m³/h and 20.000 m³/h flow rates. Cell panels are 20 mm thick and 70 kg/m³ density rock wool insulated. They provide maximum efficiency with low energy and vibration-free operation.

In a belt conveyor system, pulleys play a crucial role by altering the direction of the belt in a vertical plane. They create a continuous loop for uninterrupted operation. The pulley, also referred to as a drum, and its accompanying shaft combine to create a unified structure. Their operational features are interdependent. The evolution of conveyor pulley construction has advanced from fabricated wood to cast iron and, currently, steel fabrication. Pulleys are produced in various sizes, with the standard steel pulley being the most widely employed in conveyor systems.

It is similar to chain mechanisms in terms of its working principle, as it carries out motion transmission in a closed manner. In terms of materials, it is similar to belt-pulley mechanisms The conversion rate is fixed. The movement can be precisely synchronized as desired. Does not require lubrication. It gets very little hot during operation, It works noiselessly. It allows the use of very small diameter gears.

For the special requirements of your belt conveyor system, we manufacture for you drive pulleys, carrying idlers, throbbing drums, lift pulleys with or without internally located cone. With diameters up to max. 1,000 mm and lengths up to max. 4,500 mm, these are suitable for all types of belt conveyor system. All pulleys are turned cylindrically or spherically. The axle connections can be delivered in alternative designs with internal bearings, welded, with wedged connections or with clamping set shaft connections. Special designs such as stainless steel and/or friction linings (ceramic, rubber) and accessories (pedestal bearings) can be delivered upon request.
