(It is ideal to calculate from the actual load applied to the belt.) Overload Factor (Ks)=Ko+Kr+Ki Overload Factor (Ks)=Lo+Kr+Ki i. If the maximum torque is used once or twice per day, calculate the design power by assigning "the load correction factor (Ko) =.0" to the expression for the overload factor and then, by multiplying the maximum torque by the overload factor (Ks) derived from the said expression. ii. If the maximum torque is used very often, calculate the design power by multiplying the maximum torque by the applicable overload factor (Ks). <For ming Belts based on Spindle Motor> Calculate the design power by calculating the transmission power from the basic rotation speed and then, by multiplying it by the applicable overload factor (Ks). <For ming Belts based on Linear Drive> Calculate the design power by using the following expressions.

Be careful to avoid the ingress of foreign particles. When solid foreign particles enter during operation, it can scratch the belt and adversely affect the engagement of the belt and the pulley. In some cases, the pulley may disengage, land on the teeth of the pulley, and be cut. 2. Avoid Adhesion of oil. Oil on the rubber timing belt may wet and expand it, drastically shortening its service life. (a)take special care when using solvent type oil. (b)a small amount of lubricant or grease, however, rarely causes a trouble.. Do not use the belt in a humid atmosphere. 4. Please use a well-ventilated safety cover. 5. The service life of the belt, when used at a high temperature (80 C or more), can be drastically shortened.

Keep the belt stationary and optimize its tautness. The warp load necessary to provide the optimum tautness can be calculated from values representing the belt, its width and the span in equation A below.
