“…As shown in Fig. 10a, according to the principle of using the numerical method to solve the tooth profile [10] to [12], the u k is divided in accordance with a tooth width of 72.5 mm, 74.5 mm, 76.5 mm, 78.5 mm, 80.5 mm. 5 equidistant curves used to divide the tooth are distributed 1.5 mm from one another along the tooth depth direction.…”

“…There exist some methods for using the numerical method to solve the gear tooth profile, for instance, Xia et al, Li et al and Tong et al calculated the tooth profile of a bevel gear using the numerical method which was based on the spherical coordinates [7] to [9]. In the field of gear measurement, Guenther et al and Zhang et al put forward some new theories and methods of measuring and analyzing gears [10] to [12]. But, at present, there is no practical way of using the numerical method to solve the tooth profile of non-circular curved face gear.…”

Based on the cylindrical coordinates and the space engagement theory, which utilize a cylindrical coordinate system, an arbitrary curve equation was obtained and a method of curve expansion was established. This allows any order of pitch curve of non-circular curved face gear and normal equidistant curve parameter equations to be derived. The tooth profile points of the non-circular curved face gear can be solved using the numerical calculation method where the tooth profile intersects with the pitch curve and normal equidistant curves of non-circular curved face gear. Finally the numerical method used to solve the tooth profile of the non-circular curved face gear was proved to be accurate and correct from the small error between measured data and the data of theoretical calculation.

“…Teeth measurements include active and passive tooth flank topography, addendum and dedendum cone angles, tooth depth and pitch error on active and passive sides. Referencing the obtained geometry to the master must be based on a grid of points on the tooth flank, defined identically to the master, together with reference point M [5].…”

The purpose of this article is to demonstrate the influence of factors related to selected datums or datum systems on deviation values of gear tooth geometry, and, consequently, on the accuracy class of the aircraft bevel gear design. The item subjected to measurements was a bevel gear pinion machined by grinding on a brand new Klingelnberg G27 CNC machine tool. In the measurements, a P40 coordinate machine with a rotary table was used. The first step in the analysis was a multiple check of the accuracy of datum surfaces (the plane and cylindrical surfaces) and establishing the deviation of their dimensions and geometrical conditions (roundness, radial run-out, axial run-out). Next, tooth measurements were taken using the same setup with 13 different datum systems. The results were subjected to analysis, which yielded conclusions concerning the significance of the selection of datum systems for the correct evaluation of bevel gear accuracy. Findings indicated which datum systems are optimal and which prove insufficient to obtain reliable results. This can be used as a practical recommendation for gear tooth designers in establishing control datums for designed bevel gear members.

The crown worm drive is a new type of worm drive, it is consisting of an internal gear and a crown worm generating by the internal gear surface, and it is characterized with small size yet high-loading capacity. To satisfy the high precision requirement of crown worm tooth surface, a grinding method based on virtual center distance manufacturing principle is proposed and a grinding machine is reformed. A mathematical model was derived to calculate the theoretical probe center surface, and a measuring method is proposed to check the accuracy of crown worm tooth surface. A crown worm sample is manufactured and measured, the results show that the accuracy is 0.079mm on the upside tooth surface and 0.082mm on the underside tooth surface. The study is expected to provide the experimental foundation for the future application of the crown worm drive.
