![]() Allows some slippage - can act as a safety fuse.Raw Edge belts can be a very cost-effective upgrade to a system resulting in a significant efficiency increase due to their reduced slippage versus a V-belt and the fact that they can be installed on the existing pulleys without any need to make component changes to the drive. Raw Edge belts are used where higher horsepower capability is necessary while still requiring some slippage in peak torque conditions. Raw Edge construction belts do not slip as easily as wrapped belts due to the exposed rubber on their sidewalls. Raw Edge construction does not have fabric on the sides of the belt that engage the sheave, and have cogs, also referred to as notches, on the bottom section of the belt for additional flexibility to wrap around small sheaves. Wrapped construction should be used where maximum slippage capability is desirable. ![]() Wrapped belts have an envelope of fabric that entirely covers the external surface of the belt. There are generally two construction types available, wrapped and raw edge. They can also be used in sets of multiple belts arranged side-by-side for use on very high horsepower drives. V-Belts are available in a wide variety of cross section sizes and construction types allowing them to be an option in drives ranging from low to high horsepower. If the drive does not maintain synchronous operation the piston can contact and damage the valves. For example, the valve train of an internal combustion engine. Synchronous belt does not allow slippage as there are drives where synchronicity is a necessity and any slippage can cause damage. This eliminates one of the causes of wear and noise. Synchronous belts wrap around the sprocket by means of flexion and not by rotation of articulated parts as do chains. All synchronous belts operate on the positive engagement principle, the same principle as chains, molded belt teeth meshing with sprocket teeth. It combines the advantages of mechanical and flexible components without the disadvantages. It is a highly efficient system of power transmission. Synchronous or timing belt is a positive engagement device. For example, in a mower deck where the belt must slip rather than break the belt or bend a shaft when the blade contacts a rock or a stump. V-belts allow slippage which can be desirable and intended in drive design. It relies on tension to create friction on the sidewall of the sheave to transmit power. V-belt is a friction device and works on the principle of the wedge. Synchronous Belt (also commonly referred to as timing belt).They come in many different sizes and constructions but can be broken down into these two groups. There are two major types of power transmission drive belts. (Click to Expand) Major Types of Power Transmission Belt Economical - can be significantly less expensive than a drive designed with metal components.Ĭompactness - Belt drives can often be designed using less space than other drive components.Less weight - drives designed with belts can weigh significantly less.Clean - no lubricants, grease or oil to contaminate environment or product.Quiet - Less noise generated than metal components.In a peak torque or drive blockage situation, the belt (often the least expensive component of the drive) will break, sacrificing itself rather than breakage of much more expensive components (shafts, etc.) in the system.īelts have some major advantages over metal drive components. Belts also offer the added feature of acting as a "safety fuse" in the drive system. While the range of applications with belts in the distant past were limited by their horsepower capacity, continuous development has resulted in products that today can compete with metal components such as gears and chains in very high torque and horsepower applications. Selecting the best type of drive for a particular application is key to providing optimal performance. From large rock crushers to tiny sewing machines, the variety of applications is wide. The prevalent types of power transmission drive components used in industrial applications today include chain, gears and belts.
