When manufacturing the variable gear ratio rack, it is necessary to determine the allowable range of tooth surface error. In this study, I propose a method to determine the allowable range of machining error. At first, determine the allowable range of gear ratio error. Next, based on the allowable gear ratio error, the tolerance for machining error is determined by comparing the calculated tooth surface of the rack with the modeled error and the theoretical tooth surface. The test gear is manufactured, and tooth surface measurement and output performance measurement are performed. It was confirmed that the proposed method for machining error is useful.
