    Flat Transmission Rubber Beltings
 
 

The Transmission Belts are manufactured from the best raw-materials duly tested in our Modern Laboratory. These belts are fabricated with multiple plies of specially woven fabrics with sufficient tensile strength both in wrap & weft directions.

 

The cotton ducks (fabrics) are completely impregnated with specially formulated rubber compounds to get the best ply adhesion & excellent flex life in actual; service. The edges of belts are sealed with special binding solution to prevent ingress of moisture and fraying of the edges.

 

Samples from finished belts are tested for quality control before being shipped.

 

The belts are made in a wide range viz. type of fabrics, number of plies and widths to meet customers needs and service requirements.

PULLEY DIAMETERS: -

 

Load transmission capacity of belt is directly proportional to its speed. Large diameter pulleys with increased surface speed and consequently high load capacity (of the belts), gives a greater safety to the outer plies of the belts from the effect of excessive stress and also help to regulate the load throughout the cross section of the belt.

 

Width Of Pulley

Belt Width in MM Pulley Width in MM
Up to 125 MM Belt Width + 13 MM
125 MM to 250 MM Belt Width + 25 MM


INSTALLATION / INSPECTION & CARE OF TRANSMISSION BELTS: -

  1. For getting correct initial tension the length of the belt is cut shorter than the actual steel tape measurement around the pulleys on the following basis:

a) Belts upto 3 plies -  1.5% or 15 MM / Mtr.
b) Belts with 4. 5 & 6 plies -  1.0% or 10 MM / Mtr.
c) Belts upto 7 plies -  0.5% or 5 MM / Mtr.
  1. Both ends of the belts should be square cut at the right angles to the edges and should not have ragged cotton ends.

  2. Let the belt run for few minutes and read just the tension, if necessary.
