• Step 1 - Determine no. of teeth in engagement at small pulley
CONIDRIVE™ N10 DESIGN DATA
All CONIDRIVE™ N10 belt and pulley
systems should be designed, incorporat-
ing the design data shown below to en-
sure reliability and long-life operation.
CONIDRIVE™ N10 belts are available in Endless Style and as Belt Stock.
• Rotational Belt Drives
The power transmitting capability is de-
pendent on various parameters; namely
torque to be transmitted, the rpm of
the smallest pulley (driver), the number
of teeth on the drive & driven pulleys
and the number of teeth on the
belt. However, in all cases, the al-
lowable belt tension values shown in
Tables 1,2 and 4 must not be exceeded.
It is advisable to remain below these
values if shock loads are anticipated.
• Reciprocating Belt Drives
Reciprocating belt drives employing belt
stock materials can be selected based
on an allowable static load of 8 lbs. per
engaging tooth and belt load from static
and acceleration forces not to exceed
values indicated in Table 4.
