Product Description

MUSCLE Belt Wrapped Classical, A48MUS, A048MUS : = 48 inches, (1219mm)

MUSCLE - the ultimate V-belt

PIX’s overwhelming desire to be at the “cutting edge” in this field has culminated in the launch of the MUSCLE range of belts. Put simply, MUSCLE, is the ultimate V-belt – super-high power rating, maintenance-free, and eco-friendly. Years of consultation with their customers, and taking into account the new requirements of the changing world we find ourselves in, has resulted in PIX providing the "perfect solution"……….

- These belts are produced to comply with the latest REACH directives, RoHS regulations, and exclude all restricted chemicals as listed by the EPA in the US.
- The new belt compound does not emit any toxic substances, either during manufacture, or when running in use.
- The revolutionary design of the compound performs well in adverse conditions, such as high temperatures, UV or Ozone exposure, and chemically aggressive environments.
- MUSCLE shows remarkable performance characteristics in terms of elongation and slippage – minimising energy loss.

Main Features and Benefits:

- Extremely high power rating – up to 35% more than a regular belt
- High tensile strength – resistant to elongation and breakage
- Maintenance-Free - No re-tensioning required
- High Efficiency – up to 98%
- Highly Flexible - The standard construction allows the belt to "reverse bend" in drives with back idlers
- Extended temperature range: from -25°C up to 120°C
- Anti-static – complies with ISO 1813
- Space-saving potential, when designing drives – less belts required
- Longer service life, less down-time, reduced ownership costs

Defining V-Belt Lengths

Specifying the length of a belt can be confusing. Although it is normally recommend using effective length; outside, inside, pitch and nominal length are frequently used; and switching between these terms can be confusing!

1. Outside Belt Length (La): The outside length of a belt is usually measured with a tape under no tension. Its validity is questionable since some belts have an arched top whereas others are flat. The use of this measure therefore, would give different readings for two otherwise identical belts. It can be used only as an approximation.

2. Inside Belt Length (Li): The inside length is measured with flat pulleys or a tape measure. As with the outside length, the inside length varies with the manufacturer. This length, ideally, should not be used.

3. Belt Pitch Length (Lp): The pitch length of a belt is the length at the pitch diameter of the sheaves being used.

Classical industrial belts are specified in terms of pitch length. The pitch length is obtained by adding the pitch circumference of one sheave to twice the centre distance between two equal diameter sheaves at a specified tension. [More recently changed to datum length.]

The belt pitch length is normally the length at the belt pitch line. This line is generally located at the neutral axis near the cord line and varies with cross section and construction. The pitch of the belt and sheave is actually a theoretical point that relates to the more accurate, reliable, and useable effective diameter and effective length.

4. Belt Effective Length (Le): The effective length of a belt is the length about the effective outside diameter of a sheave at a specified tension. The effective outside diameter of a sheave is measured where the groove top width is a dimension as specified by RMA, ASAE or SAE standards. The effective length is obtained by adding the effective outside circumference of one sheave to twice the center distance between the two standard measuring sheaves at the standard measuring tension.

5. Nominal Belt Length (Ln). The nominal length is used to refer to the length and cross section of a specific belt, and can reflect the Outside Belt Length (La), the Inside Belt Length (Li) or the Belt Pitch Length (Lp) and can refer to units being in inches OR millimeters !
For example, an A38 has a nominal length of 38 inches, referring to its Li; but an SPA1280 has a nominal length of 1280mm, referring to its Lp. The nominal length is best considered as being for designation purposes.

With all the terms used, it is easy to see how identifying the proper belt-length can become confused!.

Sheave: A sheave is a wheel or roller with a groove along its edge for holding a belt, rope, or cable. The words sheave and pulley are sometimes used interchangeably. Multiple Rollers/Sheaves can be mounted on shafts and connected by belts to efficiently transfer rotational power from a power-source to a final-drivedestination or multiple final-drive destinations.

Vari-speed or Variable Speed arrangements: A sheave can also refer to a pulley which has an adjustable operating diameter for use with a mechanical belt (sometimes called a vari-speed belt). This is accomplished by constructing the pulley out of several pieces. The two main "halves" of the pulley (the angled faces) can be moved closer together or farther apart - this allows the v-belt (a wider-than-normal variable speed belt) to move higher or lower in the groove, thus altering the operational diameter, and the gearing & speed achieved. The usual construction is some sort of locking collar or set screws to secure the components, one half with a threaded central shaft and one half with a threaded center. By rotating the components one can "screw" the parts closer together or further apart, thus changing the distance between the two halves and allowing the belt to ride higher or lower in the grove. The adjustments are constrained to a specific range of size and are not limitless.
