TECHNICAL INFORMATION
Tooth shear strength, tension member tensile strength and flexibility determine belt dimensions. See p.102.
1) Tooth Shear Strength
The belt width (in cm) required to transmit known peripheral force F
maximum allowable tooth shear strength is calculated using any of the following formulae and the values from the table:
b = belt width (in cm)
F
M
P
To calculate the number of teeth in mesh, z
