The Difference in Processing of Gear Wheels by Honing, Grinding and Polishing Methods Based on the Identified Values of Surface Microroughness
The goal is to improve the accuracy and smoothness of gears, using the data of contact spots analysis, the size of the allowances for processing parts, the revealed roughness surface value of the tooth profile before processing equal to Ra = 0.01μm and after processing reaching the value Ra = 0.1μm, making it possible to exclude diamond wheel correction errors. Based on experiments during the manufacturing processes of gear wheels, the serial processing of a part have shown good results - there are no burns on the surface of the part. The hypothesis assumes the availability of technological capabilities of combined abrasive-worm wheels for the operation of gear grinding and polishing of gear wheels with a given accuracy of processing the roughness of the gear wheel and the workpiece and, as a result, allows achieving high cleanliness of the working surfaces of the gear transmission. The research methods ensure the technological support of the accuracy and smoothness requirements, quality and productivity in the processing gear wheels by choosing the specified modes, settings and regularity of changing the processing children parameters of accuracy and smoothness. A comparative analysis of the obtained was carried out.
