Are cogged V belts better?
Cogged belts can be used with the same pulleys as equivalently rated V- belts. They run cooler, last longer, and have an efficiency that is about 2% higher than that of standard V-belts.
How do you read a Gates V-belt number?
First digit in Gates number corresponds to first two digits of industry standard number. Belt length is to the nearest tenth of an inch. Example: 2450 = 4L450 Belt has 1/2” top width and 45.0” O.C. First two digits indicate belt top width.
How do you read V-belt sizes?
How to Read a V-Belt Size
- Read the outside surface of the belt for the prefix 4L or 3L.
- Read the three-digit number after the prefix to identify the belt’s length. For example, if the belt reads 4L460, you know the belt is 12.5mm wide, with a 46-inch outside circumference.
How do I choose the right V belt?
Use a cloth measuring tape (not a steel one) and wrap it around the outside of the belt. You also use a thin string to take this measurement and place it on a steel tape to get the correct length. Next, for “A” Belts (1/2” width) subtract two-inches from the outside measurement to select the correct V-belt.
Are V belts better than flat belts?
A significant advantage of flat belts is efficiency of nearly 99%, about 2.5-3% better than V-belts. Good efficiency is due to lower bending losses from a thin cross-section, low creep because of friction covers and high modulus of elasticity traction layers, and no wedging action into pulleys.
How do I choose the right V-belt?
What is the main use of a kiss idler?
The use of a kiss idler can help provide control of belt vibration and whip on drives subject to shock and pulsating loads.
Why do V-belts have teeth?
Friction drive belts rely on the friction between the belt and pulley to transmit power. They require tension to maintain the right amount of friction. Positive drive or synchronous belts rely on the engagement of teeth on the belt with grooves on the pulley.
