Calculation of load capacity of bevel gears â Part 3: Calculation of tooth root strength
détails du produit
The formulae in this document are based on virtual cylindrical gears and restricted to bevel gears whose virtual cylindrical gears have transverse contact ratios of eva This document does not apply to stress levels above those permitted for 103 cycles, as stresses in that range can exceed the elastic limit of the gear tooth.
NOTEÂ Â Â Â Â Â Â Â Â Â Â This document is not applicable to bevel gears which have an inadequate contact pattern under load.
The user is cautioned that when the formulae are used for large average mean spiral angles (Ăm1 + Ăm2)/2 > 45°, for effective pressure angles ae > 30° and/or for large facewidths b > 13 mmn, the calculated results of this document should be confirmed by experience.
