Two Types of Belt Pulley Systems That You Might Need in Your Transmission System
Belt pulleys are a vital part of any mechanical transmission system. There are many types, but two of the main ones are timing-belt and vee-belt pulleys. Here is a quick guide to each type of belt pulley.
Timing-belt pulley
In a timing belt system, the pulley wheel has teeth or pockets around its circumference. The belt then either contains holes or ridges that fit around the teeth, or lugs that fit into the pockets. This gives a tight fit of the belt around the pulley wheel, provided it is the right size.
The main advantage of this system is that there will be no slippage of the belt around the pulley, which can happen with a smooth belt and pulley wheel. This slippage can lead to variations in speed. A timer-belt system can also be given more force as it will not be lost due to slippage.
Timer-belt systems are quieter than other belt systems and produce less vibration. They also will not require lubrication. The pulley wheels can also be made from a range of metals such as steel and aluminium which will be extremely durable and will be resistant to heat. You can therefore find a system that is perfect for the environment in which it will have to operate.
Vee-belt pulley
Vee-belt pulleys work in a slightly different way. In this system, the pulley wheel has a v-shaped groove around it. The belt fits tightly into this groove. Again, this avoids the slippage that might be experienced with a smooth wheel. In fact, a vee-belt pulley is the most efficient type of belt drive system possible.
This type of belt pulley is another very reliable system that does not require lubrication and operates quietly with minimal vibration. It does not wear very quickly and any wear that does occur is usually very easy to spot. It can also not only cope well with heavier loads but actually becomes more efficient with them as the traction becomes better.
On the downside, however, this type of pulley wheel usually has to be much larger than other types, whereas the distance between the pulley wheels is much more limited.
In conclusion, the exact type of belt pulley you need will depend upon the particular system you are using it for. If you are in any doubt the best thing to do is to ask your supplier who will be able to answer any questions.
