Angular drives
BRECOFLEX® and CONTI® SYNCHROFLEX polyurethane timing belts for angular drives can be used as angular drives. Take into consideration that the timing belt can only be crossed (twisted). Eliminate the wandering-off effect.
Angular drive with 3 axes
IT/b ≥ 20
b = belt width
IT = span length
Angular drive with 2 axes
IT/b ≥ 20
b = belt width
IT = span length
Fzul - permitted tensile force
FU - Residual circumferencial force for the drive
FS - Tensile force due to crossing
With crossed timing belt applications the outer tension members suffer a higher elongation as the inner ones. Due to the larger elongation in the edge zone the permitted proportional circumferencial force for the belt in the tension members is reduced.
No power reductions or constructive special means are necessary at a ratio of IT/b ≥ 20.
At a required ratio of IT/b < 20 please contact our technical department for advise.
