Research,Simulation And Experiment Of Quadruple-arc Gear Form Grinding

The theoretical research indicate that arc gear shows significant advantages in bearing capacity, especially high precision hard tooth surface arc gear has higher bearing capacity. But the grinding of hard tooth surface is difficult. Quadruple-arc gear is a new type of arc gear. Its manufacture put forward higher requirements, because its tooth shape is complex and it has more tooth profile parameters. CNC form grinding is an effective way to improve the hard tooth face gear machining precision, and to reduce the gear tooth surface roughness. It has the advantages of high efficiency and high precision in theory. And CNC form grinding can adapt to any tooth profile curve of the tooth surface processing. Therefore, this article will be based on the principle of form grinding method, to explore and research processing and manufacturing of the hard tooth surface quadruple-arc gear. The research work of hard tooth surface quadruple-arc gear has certain theoretical guidance value and practical reference value for actual manufacturing.This subject is studying form grinding of quadruple-arc gear, the paper main contents and achievements are as follows:(1) Based on the principle of form grinding, building quadruple-arc gear form grinding geometry model and the relevant space coordinate system. Accounting to quadruple-arc gear tooth surface equation and gear tooth surfaces in contact with the grinding wheel surface condition equation, obtaining the grinding wheel cross-sectional shape through coordinate transformation. Using MATLAB software computing and graphics capabilities to calculate and simulate the grinding wheel cross-section shape.(2) According to the movement of form grinding, using SOLIDWORKS software to create virtual prototype of CNC gear form grinding machine. And import it into VERICUT software platform to combine with form grinding wheel that created with the grinding wheel cross-section shape. Write CNC program to drive the virtual prototype for machining simulation of quadruple-arc gear form grinding. Provide theoretical reference for the actual production of quadruple-arc gear.(3) Completed the actual processing of the hard tooth surface quadruple-arc gear, and assembled a quadruple-arc gear reducer. According to the design of the performance test plan to build specific test bed, then implement no-load test,load test and overload test of the quadruple-arc gear reducer. Collecting and analyzing the data of torque, speed, transmission efficiency, noise, the temperature of the oil pool.Verified the bearing capacity of the hard tooth surface quadruple-arc gear and laid the foundation for follow-up work.
