Distinguished with some basic theory and approaches of traditional tooth surface design, the spiral bevel gear with new tooth surface, namely spherical involute tooth surface, is investigated. Firstly, it improved its formational principle based on the spherical involute theory. As a key part, the parametric equation of the generating line was made a detailed derivation. To this end, fast and a...

Cylindrical gears have a wide range of applications in the manufacturing industry because of their advantages. And it is of great significance to study the design techniques and optimization methods of cylindrical gears. In this paper, parametric primary design of single-stage helical gear drive is discussed. And parametric design of the cylindrical gear is carried out by using optimized design...

This paper proposes a modified harmonic cam, which is used to design drive. Conventional drives using sinusoidal cam type pertain an elastic body concept and are thus difficult evaluate. Unlike the conventional proposed involves combination of four arcs. Such cams can be designed based on rigid concept, thus, tooth profile analyzed established gear theory. The novel by exploiting four-arc combi...

With the continuous development of national economy, big gear was widely applied in metallurgy and mine domains. So, big gear plays an important role in above domains. In practical production, big gear abrasion and breach take place often. It affects normal production and causes unnecessary economic loss. A kind of intelligent test method was put forward on worn big gear mainly aimed at the big...

This paper presents the investigation into the tooth profile features, meshing characteristics and the principle of forming circular arc tooth race cylindrical gears (CATT gears). Based on the meshing theory of the curvilinear gear, tooth surface equations and meshing line equations of the gears and rack shave been established. The graphical analysis of these equations shows meshing performance...

Effective repair of worn big gear has large influence on ensuring safety production and enhancing economic benefits. A kind of intelligent repair welding method was put forward mainly aimed at the big gear restriction conditions of high production cost, long production cycle and high-intensity artificial repair welding work. Big gear repair welding mechanism was designed in this paper. The work...
