How To Select the Drive Belt of Right Length?
According to research, determining belt length may be “confusing,” especially when individuals don’t always use the same language.
THE FOLLOWING ARE SOME OF THE ADVANTAGES OF ADOPTING THE V-BELT OVER OTHER OPTIONS:
Outside Belt Length: It is typically measured with tape under no stress. Its authenticity is questioned since some belts have an arched top while others have a flat top. The readings for the two straps would be different because of this. It’s merely a rough estimate.
Inside Belt Length: It is determined using flat pulleys (rather than v-pulleys) and a tape measure. The internal length, like the outer length, varies depending on the manufacturer.
Belt Pitch (Datum) Length: A belt’s pitch length is the length at the pitch diameter of the sheaves utilized. The pitch length of traditional industrial belts is defined. The pitch length is calculated by adding the pitch circumference of one sheave (pulley) to twice the center distance between two sheaves (pulleys) of equal diameter at a set tension.
- The length at the belt pitch line is usually the length of the belt pitch. This line, which changes depending on cross-section and construction, is often placed along the neutral axis near the cord line. The belt and sheave pitch is a theoretical concept that corresponds to a more exact, trustworthy, and useable effective diameter and effective length.
- Previously known as the pitch system for classical belts and sheaves, this datum system sets exact sheave (pulley) and belt dimensions. What used to be known as pitch diameter or pitch length is now known as datum diameter or datum length. The new catalog IDs enable all belt and sheave makers and users to utilize the same terminology.
Belt Effective Length: At a certain tension, the effective length of a belt is the length around the effective outer diameter of a sheave. The effective outer diameter of a sheave is measured when the groove top width meets RMA, ASAE, or SAE specifications. Add the effective outer circumference of one sheave (pulley) to twice the center distance between the two standard measuring sheaves (pulleys) at the normal measuring tension to get the effective length.
Nominal Belt Length: The little length refers to the size and cross-section of a particular belt. An A38, for example, has a notional length of 38 inches; a 4L440, a nominal length of 44.0 inches; and a 3V300, a nominal length of 30.0 inches. The tiny size exists simply in name and is utilized for designating reasons.
