Predimensioning calculation
Toothed-belt drive

Before starting up a toothed belt system, an overall preload F ₀ must be applied in order to subsequently ensure power transmission without causing tooth skipping ( § 1 and § 1.3). Then, during operation, the occurrence of driving T _r and resisting T _n torques produces tension differences in the belt's straight strands (figure 1 ), respectively F ₁ in the taut strand and F ₂ in the slack...
