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
