YKHS2210型弧齿锥齿轮铣齿机主轴设计+润滑密封 摘要：弧齿锥齿轮具有重迭系数大，承载能力高，传动平稳，噪音低，对安装误差敏感性低等优点，被广泛用于飞机、车辆、机床、和各种机械产品中。所以弧齿锥齿轮铣齿机的设计和制造在机械行业中占据了很重要的地位。由于其齿面的复杂性，其设计和制造也有相当大的难度。但随着数控技术的发展，传统的机械式铣齿机将逐渐被数控铣齿机所取代，这将为弧齿锥齿轮铣齿机的制造停工更广阔的发展空间。新课程课堂中如何培养学生学习数学的兴趣

The design of YKHS2210 milling machine spindle components
Abstract ：Spiral bevel gear with the overlap coefficient, high bearing capacity, stable transmission, low noise, the mounting error sensitivity etc., are widely used in aircraft, vehicles, machine tools, and a variety of mechanical products. So the spiral bevel gear milling machine design and manufacturing in mechanical industry occupies a very important position. Because of its tooth surface complexity, its design and manufacture is also difficult. But with the development of numerical control technology, the traditional mechanical milling machine CNC milling machine will gradually be replaced, it will for the spiral bevel gear milling machine manufacturing shutdown vaster development space.
The main contents of the thesis are as follows: YKHS2210 CNC milling machine spindle components of the design and demonstration program, main transmission options, YKHS2210 CNC milling machine spindle structure design, in the structural design of the spindle  compon -ent determine the location, CNC milling machine spindle stiffness, spindle lubrication method comparison and selection and milling machine spindle speed control method.
