Contact simulation and sensitivity research of quasi-transverse-double-circular gears

The contact simulation, sensitivity research, and enhanced stress analysis of quasi-transverse-double-circular gears is presented; the shape of the contact region as well as the stress distribution is investigated. The approaches proposed for modification of conventional circular gears are based on transverse-circular and normal-circular. We call it after quasi-transverse-double-circular gear. It both is different with the transverse-circular arc gear and is different with the normal-circular arc gear. Quasi-transverse-double-circular-profile means deviation of profile from a transverse-circular and normal-circular one. Using the method developed, the sensitivity of the change of centre distance in comparison with normal-circular gear is reduced. Finite element analysis of the contact and bending stresses is performed by application of general purpose computer program. Design parameter β0 of quasi-transverse-double-circular gears is designated for sensitivity studies, and result of contact and bending stresses is obtained with β0 ’s change. The theory and method are proved valid through designs.
