Using electroplating CBN hard gear-honing-tools with standard involute, the vicinity of the workpiece tooth pitch circle will be a “mid concave” error, the root of the tooth will be a “dig root” error generally. For the formation factors of the error are more complex, it is difficult to calculate errors with an exact analytical method. To this end, by using Pro/E and ANSYS software, the contact analysis of electroplating CBN hard honing process was simulated. The honed tooth surface normal deformation analysis was the important means to determine extent of tooth profile error, through the normal deformation analysis based on simulation results, the location and extent of normal deformation was determined. Practice shows that the location and extent of the normal deformation has been a certain relationship with processing gear tooth profile errors. It is provided a theoretical basis to make the gear-honing tooth surface modification as possible.

In general, using electroplating CBN hard gear-honing-tools with standard involute, the vicinity of the workpiece tooth pitch circle will be a “mid concave” error, the root of the tooth will be a “dig root” error. For the form factors of the error are more complicated, it is difficult to calculate errors with an exact analytical method. To this end, by the help of Pro/E and ANSYS/LS-DYNA software, the analysis of electroplating CBN hard honing process was dynamically simulated. Through picking up the datum from analysis results, the von mises stress distribution curve was drafted along engaging points on the tooth surface, this revealed the internal factors of the tooth profile error formation, also determined the location and extent of the tooth profile errors. It is provided a theoretical basis to make the gear-honing-tool tooth surface modification as possible, and the result is consistent with the actual processing.

Abstract With a JIS 0 class Spur Gears of AISI9310 steel, module 4, presure angle 25 degree tooth profile, the numbers of pinion teeth 21 / gear teeth 29 carburized and tooth surface hardness HRc 59, the relationships of the load and the service life (S-N) diagram were investigated by running test on the power-circulated type gear tester. MIL-L-23699 equivalent synthetic oil at 50° C were fed at a ratio of 0.8 l/min and circumferential velocity of 8.8 m/sec. Also the running performance of the gears, variation of tooth profile errors, affairs of damage, etc. were examined. Types of tooth surface fatigue mere scoring, spalling, or micropitting. A durability limit of Hertz-stress was assumed to be around 2GPa at the load cycle of 108.
