Arcuate Tooth Trace Cylindrical Gear is a new type of gear,and has the merits of higher bending strength,lower noise, better lubrication effect, more adaptable about parallelism error of axis, no axial thrustforce, etc.

The paper put forward the geometrical parameters of involute arc cylindrical gear,the flank expression and the conjugate flank expression were derived with differential geometry and the line of mesh and the line of contact were calculated.

The authors proposed a high-efficiency CNC generating method for cylindrical gear with arcuate tooth traces,by means of a standard hob and studied the hobbing mechanism.

A study of the circular arc gear reliability based on improved FOSM method

Through processing super circular arc gear on numerical control machine tool,has explored the technology of numerical control processing about super spare parts,guaranteed the processing precision of spare parts,improved production efficiency and solved the processing problem of super spare parts.

Based on the fuzzy mathematics and the theory of the reliability design, the mathematics model of the fuzzy reliability design of the circular arc gears is established.
