Product Description

Cogged Classical ZX45 Belt, ZX045 : LI = 45 inches, (1143mm) : mass = 0.064kgs. Minimum pulley diam = 40 dp (mm)

Raw Edge Belts are of three types:
1. REC Belts (Raw Edge Moulded Cogged Belts)
2. REP Belts (Raw Edge Plain Belts)
3. REL Belts (Raw Edge Laminated Belts)

Special top layer with fabric:
The rigid layer on the top restricts top layer cracking and gives uniform tension on cord ends. Top fabric gives better support & protection from environment.

Tough Tensile Member For Greater Strength:
Specially treated stabilised polyester cord provides high tensile strength with minimum stretch which in turn gives V-belt superior resistance to fatigue & shock loads.

Moulded Cogs:
Moulded cogs allow the Raw edge cogged belts to operate even over smaller diameter pulley at high speeds. The cogs also help in reducing the bending stress apart from providing the higher surface area for proper heat dissipation.

Polychloroprene Cushion Rubber Compound:
Ensures the best possible bond between the base compound, the tension cord & rubber impregnated fabric top surface that provides long service without cord separation.

Fibre Filled Polychloroprene Base Compound:
Gives increased power transmission capability, superior transverse stiffness & high wear resistance.
• Speed ratios up to 1:12 are possible: This eliminates the needfor multi stage drives.
• Temperature range: -18ºC to +100ºC
• Maximum recommended belt speed is 30 m/s*
• Antistatic, Oil and Heat resistant
• ATEX certified FRAS belts are also available

It is recommended to use these belts in borderline cases if difficulties are anticipated in using wrap construction belts.

The advantages of Raw Edge Moulded Cogged Belts over Wrap Belts are of great importance in following cases-
1. Drives with very small pulley diameters
2. High ambient temperatures
3. High belt speeds
4. High level of power transmission

The sections covered under this category are -
ZX, AX, BX, CX, XPZ, XPA, XPB, XPC, 3VX, 5VX & 8VX which offer the best techno economical solution for above conditions. PIX also manufactures entire range of Raw Edge Banded Belts to suit various applications.


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.
