Study Of Electromechanical Integrated Sine Oscillating Tooth Drive

With the rapid development of modern science and technology, the requirement ofmotion and dynamic transmission in manufacturing industry has been taken seriously. Thedevelopment tendency of electromechanical integration has become the main direction ofthe industry development. Electromechanical integrated sine oscillating tooth drivemechanism has many outstanding advantages, such as compact volume, light weight, largerange of transmission ratio and excellent performance of lubrication, which can be appliedto broad areas. This thesis designs the electromechanical integrated sine oscillating toothdrive mechanism, completes the dynamics and torque analysis.First, the dynamic model of electromechanical integrated sine oscillating tooth driveis built. The whole system is simplified into three subsystems for free vibration analysis.Natural frequencies and main modes of the system and subsystems are calculated. Modeanalysis is carried out with the system divided into rotation, oscillating tooth and simplemodes. The expression of sensitivity is deduced, and how the parameters influence thesensitivity is analyzed as well.Second, the stress distribution between the oscillating tooth and other parts ofelectromechanical integrated sine oscillating tooth drive mechanism is calculated. Toothforce is solved concretely according to the parameters of design example, and the outputtorque formula of the system is presented based on the forces of live teeth and othercomponents. How parameters influence the system’s output torque is also analyzed. Allthese provide theory basis for the actual design and processing.Finally, the3D model of electromechanical integrated sine oscillating tooth drive isbuilt by parametric design method with the help of Pro/E. The inner and outer raceway ismanufactured by German five-axis linkage CNC machine. Then the model machine ofelectromechanical integrated sine oscillating tooth drive mechanism is manufactured andassembled. The experiments of system torque output and transmission ratio are carried out,which verify the theoretical calculation.
