Energy is essential for driving the machines and equipment for various applications. Different industries use different power transmission products and sometimes a combination of all to suit their respective needs. So if someone ask which is the best power transmission technology, it will be little difficult to select one over another as these drives come with their own sets of pros and cons.
The only determining factor, therefore, should be the task that needs to be accomplished using the power transmission technology. And of course, the budget too. About the Author: Jack Warner is a tech enthusiast who likes to stay updated with the latest norms in the technology world.

Knuckle Joint A knuckle joint is used to connect two rods which are under the action of tensile loads.
However, if the joint is guided, the rods may support a compressive load. A knuckle joint Plastic Material Definition Of Plastics : i Plastics: Plastics are basically, the synthetic organic materials of high molecular weight, which can be moulded into any desired shape by the Skip to content Home - Blog - Machine Design.
Table of Contents. Belt drives are called flexible machine elements. Flexible machine elements are used for a large number of industrial applications, some of them are as follows. Used in conveying systems. Used for transmission of power.
Mainly used for running of various industrial appliances using prime movers like electric motors, I. Engine etc. Replacement of rigid type power transmission system. Flexible machine elements has got an inherent advantage that, it can absorb a good amount of shock and vibration.
It can take care of some degree of misalignment between the driven and the driver machines and long distance power transmission, in comparison to other transmission systems, is possible. For all the above reasons flexible machine elements are widely used in industrial application. Types of belt drives:. At the junction side, it rubs and therefore it wears and tears off.
The fast pulley is mounted on a shaft with keyed joint and the loose pulley runs freely on the shaft and it is incapable of transmitting any power. Another term in that is when multiple machines are working from a single power source then in this condition, each machine has provided with this fast and loose cone pulley.
Here in stepped cone pulley, there are more pulleys attached of different diameter one adjacent to another. Stepped cone pulleys are used where they have to change gear or speed of driven shaft change frequently like a machine Lathe , Milling and more.
The diameter of the driving and driven pulley is such that when we wanted to shift to another pulley the same belt will operate. Jockey pulley is like an idle pulley and which is used for increasing the angle of contact in an open belt drive. Hence increasing the angle of contact steer to the increased power transmission capacity of the drive.
This one pulley is mounted nearer to the smaller pulley and we can say also this is placed on the slack side of the belt.
It jockey or idle pulley helps to increase the angle of contact of the belt, so that belt tension is increased and also the drive provides a high-velocity ratio. It is used where low power is required and speed is more. Generally, the shaft distance is between 5 to 10 meters. V belts are used where shaft distance is less than 2 meters and also used for moderate speed and high power.
Circular belts are also used where smaller initial tension is required and absences of vibration and noise are there.
Timing belts are a positive drive. For choosing belt material, the material should follow some properties which are:. The leather belt you might have seen in your daily life.
Yes, it is. This belt is more expensive than other belts made of cloth or recycled materials. And you know, to become a leather belt strong, the one layer of leather is joint to another layer to become stronger and increase the thickness of the belt.
The selection of belt drive depends on several factors. Some of them I am listed out here:.
