Tooth root bending stress and surface contact are two major determinants of the load carrying capacity gear drives. Generally, a high ratio has potential to enhance strength. In this paper, basic procedures methods for constructing high-contact-ratio (HCR) internal spur pair with arc path presented. The effects design modification parameters such as deflection angle, addendum coefficient on dri...

A procedure to build up a dynamical model of the gearbox with spur involute mesh is being described. The main attention is paid to the design technology of the cylindrical bodies elastic contact models. To track geometry of contact implicit equations of algebraic/transcendental or differential-algebraic type are being used. At the same time dynamical models of the bodies involved, gearwheels an...

Abstract Traditional gear measurement results are used to classify a tolerance grade in accordance with ISO 1328-1:2013 but as more stringent requirements placed on performance it is important also characterise related features properly the flank surface. However, uncertainty of machines not improving at same rate requirements, and uncommon have less than 10 μm tolerances be measured 1–3 capabi...

Generating-line method, which is based on the generating process of spherical involute curve, is a new processing theory of cutting ideal spherical involute gears. Based on the principle of the new method, this paper expands the traditional geometrical relationship into the cutting geometry of generating-line method, and proposes the base-cone parameters with their formulas to provide necessary...

Oil pump in diesel engine has significant effect on energy consumption and environment pollution. In this paper, the modeling and simulation of a gear oil pump used in a diesel engine and its fluid flow analysis by a solver has been explained. Also the optimization and redesign of it has been discussed and then the outcomes have been compared with the experimental and previous results. The t...
