Belts are the mechanical elements mainly used for the power transmission without any phase shift. They’re loops of the flexible materials that are used to connect many rotating shafts, often parallel. The correas de transmisión are used as transmission element, which will efficiently transmit movement or power.
Because of several advances in the belt technology, now they can meet the high-power demands whereas being very safe, durable and efficient. In this post, we will take the detailed view at different kinds of the modern belt drives & types.
Design & Selection Consideration for Belts
While designing and choosing V-belt for system, there’re various factors that you need to check out ensuring the selected component demonstrates right performance characteristics. Some important considerations to remember include:
Environmental & operating conditions in which V-belt is subjected influence what kind will be perfect for you.
Some factors that you need to consider include intermittent, operating speeds, and continuous operation, layout (serpentine and quarter turn), misalignment tolerance, belt efficiency, transmitted power, and exposure for harsh conditions (temperatures, ozone, abrasives, and oils).
That depends on factors that are very important, industry professionals will select from a wide variety of the light-duty and heavy-duty, V-belts.
The total tension needed in belt drive mainly depends on type of the belt, design horsepower, as well as drive rpm. As running tensions will not be measured, it’s important to tension the drive statically.
Force or deflection method is often used. When the calculated force gets applied to center of the belt span to get deflection, recommended static tension will be established. Most of the design catalogs offer force & deflection formulas
With very little tension in V-belt drive, there is high chance slippage will occur and also lead to the spin burns, overheating of belt, cover wear, and overheating of the bearings. Not high tension in the synchronous belt causes the premature tooth wear and ratcheting that can destroy this belt and can break the shaft.
While installing the new belt, its installation tension must be set much higher. Normally 1.4 to 1.5 times its normal static tension, it’s essential because drive tension will drop fast during seating-in procedure. The extra initial tension doesn’t affect bearings as it decays fast.
How to Properly Take Care Of Drive Belts?
- Keep your belts away from the engine oil, moisture or water and debris.
- Ensure components are in very good shape and avoid stress on belts
- Perform routine checks
- Replace them regularly or when needed
