How Do You Measure PK Belt Length

Due to the closed nature of the transmission PK belt, direct length measurement includes the use of specialized measuring tools and inherent calculation formulas. In fact, when calculating the length of the transmission PK belt, several parameter values need to be measured, such as the diameter of the large and small pulleys, and the distance between the center of the large and small pulleys.

How do you measure PK belt length                                

Belt length calculation formula

lb = ((df + dm) 1.5708 ) + (2 lfm)

lb=belt length, df=diameter of the large pulley, dm=diameter of the small pulley, lfm=distance between the center of the large pulley and the center of the small pulley

Measurement method of toothed belt

The calculation of the length of automobile belts also requires conversion. The tooth shape includes O-type, A-type, B-type, and C-type, and the tooth shape includes the inner and outer circumference. La represents the outer circumference, Le represents the effective length, and Li represents the inner circumference.

Length conversion

The REMF-X on the black belt is followed by inches, and the width and length on the belt are measured in millimeters.

Type O and type A: Li+50=La inches * 25.4 ≈ La

Type B: Li+60=La (inches+1) * 25.4 ≈ La

Type C: Li+80=La inches * 25.4+30 ≈ La

For example, 17 * is a B-type belt, 17 * 1200 (1135Li) REMF-8460

1200 is the outer circumference, 1135 is the inner circumference, conversion method: (46.0+1) * 25.4 ≈ 1200mm

The above is the measurement method for transmission belts, including How do you measure PK belt length and the measurement method for toothed belts.
