Gear pair of the design apparatus, gear pair design program, a design method of the gear pair, and the gear pairs

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for designing a gear pair easily setting design information for machining with good yields and efficiency a good gear pair that can withstand practical use.;SOLUTION: In the apparatus for designing a gear pair, a computing unit 6 sets a plurality of patterns of groups G of tooth surface correction amounts, each of which is a combination of values of tooth surface correction amounts; when performing tooth surface machining using items resulting from basic items plus the tooth surface correction amounts, the computing unit simulates for each group G of tooth surface correction amounts a plurality of patterns of gear pairs manufacturable within the range of machining errors set for each finishing method, and computes tooth surface error distribution information for each tooth surface of each gear pair. For each finishing method, and for all the gear pairs simulated within the set range of machining errors for each group G of tooth surface correction amounts, the computing unit computes each transmission error amount E in a plurality of meshing conditions based on the corresponding piece of tooth surface error distribution information, and extracts the best group G of tooth surface correction amounts. The final finishing method is selected from the finishing methods from which the best group G of tooth surface correction amounts is extracted.;COPYRIGHT: (C)2010,JPO&INPIT
