As much as one third of all electric motors used in commercial as well as industrial sector utilize belt drives. The reason for using such belt drives is that they offer flexibility in placement of motor in context to load.
Belt Transmission & Efficiency
Sheaves or pulleys with contrasting diameters make it possible for driven equipment’s speed to be decreased or increased as per requirement. If the belt transmission system has been designed in a proper way then it offers better efficiency, lowers noise, requires less maintenance and reduced lubrication.
Nevertheless, some belts generally tend to be more efficient in comparison to others and provide better cost savings in terms of energy used.
V And Cogged Belts
It is worth mentioning here that many of the belt drives many use of v belts which utilize trapezoidal cross section for creating wedging action over pulleys for increasing friction as well as for improving power transfer capability of the belt.
In case of heavier load these are joined for better performance. Theses have almost ninety five percent efficiency when they are installed but the level of efficiency depends on other aspects like size of the pulley, over or under belting, torque being driven and design of the belt.
The efficiency tends to go down with time in case slippage takes place if belt in not re-tensioned on periodic basis.
Functions of Cogged Belts
Cogged belt manufacturers design these belts in such a way that they have perpendicular running slots across length of the belt. The advantage of these slots is that they help in reducing bending resistance belt has.
Another good thing about them is that these can be utilized with pulleys that use similarly rated v belts. Apart from that these last longer, run cooler as well as have efficiency which is about 2% more than that of any normal v belt.
Additionally, by using such belts it is possible to lower inefficiencies present in ventilation fans because of bending resistance as well as belt slippage.
In case of centrifugal pumps and fans, these are developed by cogged belt manufacturers in a way that they provide better vibration damping. Furthermore, they are a better choice in comparison to synchronous belts where abrupt torque changes occur because of shock loads.
If you are looking to purchase this type of belt for your industrial use then Polydrive is the best place to buy them from. They have a very good collection of these belts of very high quality and also are available for most affordable pricing.
