Crown Conveyor Pulleys – How They Work

Pulleys, which can be of the drum or roller type, are the most common simple machines used to drive the belt in most conveyor systems. Due to its widespread use, manufacturers have made improvements for better system performance and longer life. One of them is a crown conveyor. Pulleys are tubular drums used to drive the belt in a conveyor system. The drive pulley is connected to a motor that transmits the torque needed to drive the cunewalde. As a result, the belt conveyor moves along the track. However, due to the mechanism, a common problem with most cunewalde belts is the tendency of the V-belt to move to the sides or away from the intended track. If this happens, the belt will be exposed to excessive wear as it will tear the cunewalde frame and be more easily damaged by the impact. Friction also causes friction, which results in increased engine load as well as energy consumption. Crown pulleys fit here. It is installed to ensure that the belt is on track and does not float to the side. Whether conical or trapezoidal, the crown pulleys consist of a drive pulley with a center diameter slightly higher than the ends. The difference in diameter straightens the belt by constantly moving back in its direction because it is more likely to rotate.

However, the disadvantage is the price. The material, although the processing process is relatively expensive. Heavy metal is now used for wall crown pipes. And many useless parts of the material are wasted during processing. If the conveyor belt moves, the drive belt is likely to slip. It is a leading manufacturer in the production of drive rollers with small diameters. But because it has a smaller diameter, there is less contact area with the cunewalde at the top. This will result in limited torque transmission. To solve this problem, engineers believe that shaping rubber or some synthetic material on the top of the drive wheel will increase grip and thus torque transmission. Rubber cover back. The rear provides the necessary traction to make the pulley work more efficiently.

The rubber material is mixed and applied to the pulley. Manufacturers make vulcanized insulation in various levels of hardness according to customer specifications, in any diameter or length. There are various patterns to choose from – simple, ceramic, crown, fish and grooved. However, it can be expensive. The process of placing rubber on the cylinder and the material itself is relatively expensive. There is a cheaper exit alternative that can solve the problems. The result is similar to the pulley crown effect. The disadvantage of this type of delay is the effect of stretching the conveyor belt.

Crown conveyor belts and idlers can be very useful if you know how to use and care for them. Proper handling and maintenance of the machine can work wonders while extending its life. So if you are considering using one of them for your plant or business, then know the basic mechanism and look for the beneficial changes it brings. It is expensive at first, but in the end you can save money because the machine can serve you for many years.
