新型圆弧齿线圆柱齿轮传动应用基础研究

This Project is to study a method of design and manufacture for a new type of arc curve cylindrical gear drive that can be used in some heavy mechanical equipment requiring high speed, heavy-duty, high-accuracy, high reliability and high efficiency. According to the method of processing hypoid-bevel gears, the arc curve cylindrical gear has been created. Cutting tools have been set up in the big dise and its spin axis is different planes orthogonal between the spin axis of the gear that has been cut. When the spin axis rotats continuously the cutter path is one passage circular arc in the cylinder and the cylinder has at once pure rolling.The cylinder is to be cut into an arc curve cylindrical gear. Since the cutter pass is a ruled surface the grinding wheel can be manufactured. When the profilegrinding is used for the new type of gear its surface has high-precision. The new type of gear transmission has characteristics of the heavy load-bearing capacity, the high efficiency and easy processing and manufacturing. This project is to study the theory and key technology of mesh theory, mesh performance, geometrical features, parameter optimization, lubrication mechanism and method of measurement for the new type of gear transmission. The correlation theory system and design procedure will be set up and the structure form will be presented in the project. The tasks ,the prototype device manufacture and its bench test,will be completed and the process program of industrialization production is to be set up for the type of gear transmission. The research result is to lay the applied foundation for the arc curve cylindrical gear drive that can be widely used in machine tools, wind power generations and national defense equipments.
