The invention of the belt transmission was one of the cornerstones of the industrial revolution. Since then, it is difficult to imagine the functioning of machines or production lines without their use. Although they are durable, they are also subject to wear. How can you tell when a pulley needs to be replaced?
How is the belt transmission constructed?
The belt gear folds up with active and passive pulleys and an elastic beltthat transmits the drive. The gears are characterized by a very wide range of applications and incredible reliability. They are present almost everywhere: in car engines, agricultural machinery, conveyor belts or equipment used in industry. But what if one of the wheels is damaged as a result of use?
Pulley wear
Pulley wear is mainly due to its abrasion. In the case of improper matching of system elements, improper setting of the pulley groove angle or misalignment of angular and parallel alignment, the pulleys may show slight scratches, abrasions or deformations, which over time lead to the formation of gouges. Most qualifying mechanical damage toothed pulley for as soon as possible replacement can be seen with the naked eye. How can you tell if the wheel is not working as it should?
Signs of wear on the pulley
One of the first signs of a pulley wear will be a belt malfunction - excessive noise or unusual noises made by the device. Another disturbing symptom may be excessive increase in wheel temperature. Here, the most common causes are the bearings and lack of proper lubrication or contamination. Another symptom of pulley wear is twisting the belts - here the cause may be the lack of straightness in the alignment of the wheels or the wrong groove profile.
Although belt transmissions are virtually maintenance-free devices, it is worth spending some time on their proper configuration and taking care of regular maintenance.
