“…Jiang Weixu [17] and Wang Shaojiang [9] realized the CATT gear's simulation processing by using a rack cutter in UG NX8.0, but the surface of the CATT gear is rough, and the model could not be used for analysis and processing. Many researchers investigated the contact strength, bending strength, gear transmission errors, computerized design and simulation of meshing by applying the finite element analysis [18][19][20][21].…”

To reconstruct the tooth surface of a circular arc tooth trace cylindrical gear (CATT gear), one needs to create an accurate 3D model and investigate geometric features of the tooth profile. According to the processing principle of the rotating knife dish milling, and using the space meshing theory and differential geometry, the tooth surface equation and the tooth profile of CATT gears have been deduced. Then, the tooth surface reconstruction of CATT gears was done and a 3D model was created. Next, based on theoretical deduction, it was proven that the profile of the middle section was involute, and the other section was hyperbolic. Finally, the influences of the design parameters on the tooth profile were investigated. The general tendency is that the gear tooth thickness becomes thinner as the gear width increases and the tooth line radius decreases, and the tooth profiles of the concave and the convex tooth surface may intersect. The influences of the module need to be discussed separately. The tooth thickness deviation increases as the module increases. But the relative tooth thickness deviation is opposite. Therefore, it is suggested that R T  (3-4)b and the module should be large to improve the bearing capacity. The results of the investigation provide a reference for the design, profile modification, lubrication, and measuring of CATT gears.

To reconstruct the tooth surface of a circular-arc-tooth-trace cylindrical gear (CATT cylindrical gear), a 3D model has been developed and the contact characteristics have been investigated. Based on the development principle and meshing theory, the tooth surface equation, tooth surface curvature equation and tooth surface contact ellipse equation of the CATT cylindrical gear were deduced, and it was proved that the contact was a point contact. Then, the tooth surface was reconstructed and a 3D model was developed. Next, by performing the finite element analysis and meshing impression experiment, it was proved again that the contact is the point contact, and the contact area became an ellipse under loading. Finally, the influences of the design parameters on the contact ellipse were investigated. The general tendency is that the elliptical contact area increases from the tooth root to the gear top; the elliptical contact area decreases when the modulus and the gear tooth number near the tooth root increase and it increases when the modulus and the gear tooth number near the tooth top increase; the elliptical contact area increases when the tooth line radius increases. The elliptical contact area decreases in a cliff-like manner near the tooth top. The research results provide a reference for the design, profile modification and lubrication of the CATT cylindrical gear.
