Belt drive systems are important when it comes to power transmission and material handling.
Certain factors should be considered when setting up the belt drive system to ensure that they work efficiently.
If you neglect any of the factors that I will be sharing with you in this article then your belt system drive will not work effectively.
Without further ado, let me share with you what you need to know about this topic.
Factors affecting the efficiency of belt drive system;
1. Shaft alignment.
When we are talking about a belt drive system, the shaft is a very important part of this system.
There is no way the belt drive system will work if there is no shaft on the system.
The main thing that will make the belt drive work efficiently is how the shafts are aligned.
If there is any misalignment of the shaft the belt drive system will not run effectively.
This means the material being handled or the power transmitted by that belt drive will have an issue.
If it’s material being handled; the handling of that material will be poor and if it’s power transmission it won’t be that effective.
For instance, if you expected to transmit 90% power from the motor to the job you are working on, you will find that you are only transmitting about 50%.
So, if you want to ensure that the belt drive system is working efficiently you have to make sure that the shaft is properly in line, as this will help to gain uniform tension across the belt.
2. Pulley’s distance from each other.
The distance between the pulleys also plays a big part in the efficiency of the belt drive.
You have to know that when the belts are connected to the pulleys there is a certain angle that should be maintained (angle of contact or lap).
This angle affects the amount of power transmitted or the material handled by that belt drive system.
The pulleys should be in a way that they are not too close together or too far apart from each other.
If the belts are too far apart the angle of the lap will be affected thus resulting in the ineffectiveness of the belt drive system.
The pulleys should not be too close together so that the arc of contact on the small pulley will be as large as possible.
This will ensure that the power transmitted by the belt drive system is efficient.
On the other hand, if its materials are being handled by the belt drive system it will be handled effectively.
So, if you mess up with the distance between the two pulleys you will end up making the belt drive system ineffective.
Also, if the pulleys are too far apart this will bring issues as the belt will way heavily on the shafts which will eventually increase friction.
As you know friction is not good in machines, as it will cause wear out of some parts e.g the bearings.
The other problem that you will be causing is the wear of the belts also.
So, this is an important factor you should check when setting your belt drive system.
3. The type of belt you use on the system.
The type of belt you use on your system will have a huge impact on its efficiency of it.
Two main types of belts are used on a belt drive system, we have the flat belt – which is the common belt used in most belt drive systems. The other one is the V-Belts. These are the grooved belts.
So, if you will choose to use any of these belts then know that they will have a certain effect on the efficiency of your system.
If you want moderate power transmission then you should choose to use the flat since it’s very effective for that, as long as the pulleys are not more than 10 metres apart you are good to go.
On the other hand, if you want to transmit a great amount of power transmitted then you should choose to use the v-belts.
Use the v-belts when your pulleys are near each other.
This depends on your needs, if you need great power transmission and your belt system drive to match the criteria I have talked about then you should go for the right belt.
I hope you have known how these belts affect the efficiency of your belt system drive.
4. The power output of the motor connected to the belt drive system.
For the belt system drive to work the way you expect it to then you will need to connect it with a motor.
The kind of motor you use also will have a great influence on the efficiency of your belt drive system.
You can’t use a faulty motor on your belt drive system and expect it to work effectively.
For instance, if you want a belt drive system that will provide you with a high starting torque then you should think of using a slip ring induction motor, but if you go for a squirrel cage induction motor you will not get the starting torque you want for your belt drive system.
So, the motor you choose to connect to your belt drive system has a great impact on the efficiency of the machine.
