【Abstract】 In order to help the students to understand the movement of planetary gear mechanism in different working conditions,and to verify the formula of transmission ratio of planetary gear mechanism,we have researched and designed a set of demonstration teaching aids of planetary gear mechanism,including the mechanical structure and data acquisition system. The planetary gear mechanism was driven by motor for 12 V. It was also accessed to the real- time motion parameters of the mechanism through the sensor and the Lab VIEW data acquisition program of itself. This way,the actual transmission ratio is figured out compared with the theoretical data and then to be compared with the theoretical data. The experiment clearly illustrates that The teaching aids are reasonable in design,portable and intuitive in demonstration of the planetary gear mechanism movement.更多还原
