Gear has been used in machine elements as part of power transmission in many kinds of machines. The performance of a gear has a influence on the performance and accuracy of the machine. Therefore, research on gear has been actively carried out so far. In order to improve the performance of the gear, I carried out optimization design of the gear geometry.
In this paper, I used Romax Designer to optimize the gears in cross Drilling / milling unit. Romax Designer is a dedicated gearbox design and analysis program. The geometry of the gear is repetitively modified by micro geometry method, and at the same time the transmission error is checked to make an optimized gear shape. It was confirmed that the stress distribution of all the spur gears was concentrated at one end of the gear tooth surface, while the stress distribution was shifted from the one end to the center of the tooth surface after the optimum design. The transfer error and maximum stress were also reduced after the gear tooth surface was modified. All of these processes reduce trial and error before producing real gears.
