What is the Secret of Pulleys and Belts?

As a CHERY Tension Pulley Wholesale, share with you.

Pulleys and belts are the main components of transmission equipment. Whether they are "good fit" has a serious impact on the operation of the equipment. Therefore, when we use the belt, we should consider matching it with the pulley of the engine. If it is used incorrectly, the service life of the belt will be seriously affected, and the machine will not operate normally.

The secret of pulleys and belts

For example, some engines use a flat fan belt, and the flat belt is installed well with the pulley, which can make the belt life longer. The V-belt corresponds to the V-belt, and the corresponding pulley model should be selected. If an error occurs, it should be corrected in time. Phenomenon: There are abnormal noises when the engine is running, such as rustling, squeaking, buzzing, etc., when the engine is stopped, you can move the belt intermediate pulley by hand to check whether there is a gap. If you find a large gap, replace the belt Intermediate round.

On the impact of the pulley on the belt: the belt is the link that transmits power. When the power is used to drive the belt to rotate, the swing of the intermediate pulley will cause accelerated wear of the belt. If the belt intermediate pulley is blocked, the belt will be polished, and sometimes the pulley will fall off. The belt is not grooved, so that the power of the entire transmission equipment is interrupted.

Speaking of common problems with pulleys, let's take a look at the inspection method of the belt.

The belt inspection mainly includes two aspects: belt tension and belt wear.

1. Check the belt tension: Check the belt tension with your thumb and forcefully press the belt between the two pulleys. The pressing force is about 10kg. If the belt pressing is about 10mm, the belt tension is considered appropriate. If the reduction is too large, the belt tension is considered insufficient. If there is almost no reduction in the belt, it is considered that the belt tension is excessive. When the tension is insufficient, the belt slips easily. When the tension is too large, it is easy to damage the bearings of various auxiliary machines. For this reason, the relevant adjusting nuts or bolts should be loosened to adjust the belt tension to the best condition.

2. Belt wear check: The belt will wear out when used, and the old belt will wear out seriously, causing the contact area between the belt and the pulley to decrease sharply. At this time, as long as the belt is pressed hard, the belt will sink deeply into the groove of the pulley. The belt rubber also has an aging problem. If the belt rubber is seriously aging, it must be replaced with a new belt in time.
