The specific tooth force Ftspez is the maximum force N a belt tooth with a width of 1 cm can transmit. This value depends on the rotational speed of the drive pulley. The calculation takes into account each identical carrying values for each meshing tooth. With more than 12 meshing teeth ze is limited to 12.
Ft = Ftspez * ze * b
Ft = Tangential force
Ftspez = Specific tooth force in N/cm
b = Belt width in cm
ze = Number of meshing teeth
zemax = 12
