Impact of Tooth Shape Parameters on Strength Safety Coefficient of Herringbone Planetary Train

Abstract:

The influence of tooth profile parameters on the strength safety coefficient can provides the basis for the design of high strength herringbone planetary train system. Through calculation of the three strength safety coefficients (contact strength, bending strength, bonding strength), curves of the relationships between the tooth shape parameters (addendum coefficient, tip clearance coefficient, spiral angle) and the strength safety coefficients have been obtained and the impact of tooth shape parameters on the three strength safety coefficients have been analyzed. The research results show that the bigger addendum coefficient can be selected for the design of high strength herringbone planetary train system. In order to satisfy bending strength, no-undercut and lubrication condition the smaller tip clearance coefficient should be taken. The strength safety coefficients are bigger with the increase of spiral angle, so a bigger spiral angle may be appropriately chosen.
