The Design, Manufacture, and Analysis of the Continuous Oil-Air Lubrication System of Plunger Type for High Speed Spindle

碩士機電工程學系[[abstract]] The study is to devise an oil-air lubrication system, which can be employed to bearing lubrication, especially high-speed bearing. The consumption of the lubrication oil in the oil-air lubrication system is little. The stability of the lubrication oil will influence the temperature rise and the friction torque of the high-speed spindle. Therefore, the study is to design an oil-air lubrication system to provide a stable output control of lubrication oil. The system can offer minimum amount of lubrication oil to the spindle continuously. The system is divided into two parts: the drive mechanism and the oil circuit system. The first part is framed by a mechanic cam and then performed the constant stable output by dual columns. In order to make the output as stable as it can be, the movement of the dual column should work in uniform motion. Therefore, the flat cam is obtained with the help of the mechanical dynamics software ADAMS. After be constructed and tested, it can serve as devised. In the design of oil circuit system, the main structure is equipped with different check valves, which are made of Acrylic. The system has been tested to see its volume effect in different structures. The result shows that the check valve of double layers rubber pipe has better volume effect. Thus, based on the design, tested with regular oil output, minimum oil output, the particle size of the oil-air output and the variety of density. It is obviously that the system can reach the expected goal after the tests. Then, the lubrication system is constructed with 8 outlets
