In the market, there are various kinds of mechanical parts. All of them, small or big, are very important for the whole machine. Among the numerous components, belts are rather simple and common, meanwhile, they are also indispensable.

A belt is a loop of flexible material used to link two or more rotating shafts mechanically. Usually, belts are looped over pulleys. They cooperate with pulleys very well to achieve certain function. They may be used as a source of motion, to track relative movement, or to transmit power efficiently. When the designed belts and pulleys are working together, then the power transmission can be achieved. Compared to other parts, belts are the cheapest utility for power transmission between shafts that may not be axially aligned.

Belts have a wide usage. For example, drive belts are commonly used for power transmission. It is a seamless belt that is used to transmit torque and power from one wheel or shaft to another in a machine or any mechanical system. As mentioned above, the belts work together with pulleys to have the power transmission.

In vehicles, there is a drive belt system which powers the water pump, the air conditioning, power steering, brakes and alternator among other components. Because power is quite important for vehicles to run regularly, obviously, this important component also plays a very important role in transmitting the power. As a result, it is very necessary for machine owners to take care of the drive belt and check it on each time they change the oil. This intends to ensure that it is working regularly without any problem, which will also guarantee the proper work of the whole system.

Then, how to check a drive belt? Firstly, the tension and general condition of the belt should be checked. This step is very useful to ensure whether the vehicle is in proper condition. When inspecting the drive belt, you should pay attention to many aspects. For instance, cracks, the presence of frays, and missing ribs, etc. Any of these problems should be dealt with.

Secondly, you should ensure that you inspect the entire length of the belt surface. Except the above mentioned elements, sometimes, vehicles may produce a squealing sound which may be a sign of losing or wearing out of it. This is because a loose belt may slip and subsequently produce a squealing sound, causing the alternator to vibrate rapidly, thereby wearing it out more easily. If the sign of wearing out is quite obvious, it is better to replace the drive belt to ensure the safety.

Addition to the above aspects, it is also very important to inspect the drive belts before problems appear. If there is any problem with the drive belt, you should find out the reasons. And you should replace the drive belt if necessary. The proper status of the drive belt may ensure that the vehicle can run under a good situation.

According to the above analysis, we can safely draw the conclusion that the Drive Belt is a rather important component for power transmission. And the appropriate inspection of it becomes necessary. You should make sure that it is under the proper situation.
