二．机床主要性能和结构特点

1．本机床系三轴数控弧齿锥齿轮铣齿机，即摇台运动（X轴），工件主轴运动（Y轴）、床鞍进给运动（Z轴）。

   三轴均可实现数控轴控制和联动。刀盘的旋转（S轴）速度由变频电机控制实现无级调速。

2．本机床摇台和工件箱部件均采用高精度双导程蜗轮副传动，并采取了多项增强结构刚性和传动刚性的措施，

   保证了本机床加工精度并提高了机床生产率和使用寿命。

3．本机床装有刀倾角为30°的刀具主轴倾斜机构，不但可加工最小传动比为2.5：1的半滚切主动轮，

   而且能实现更好的轮齿接触区修正。

4．本机床调整无需更换挂轮，减少了机床调整时间。

5．本机床采用数控设定的进给运动，简化了用户操作并有利于提高切齿效率。

6．机床的数控系统，主要电气、液压元件、轴承和密封件均采用优质进口件，从而保证了机床的可靠性。

7．本机床配置独立密封的电气控制柜，可选配空调或热交换器。

8．本机床可配置安全防护罩和自动排屑器。

1. Main Usage of Machine

On this machine, many cutting methods can be adopted for roughing and finishing Spiral Bevel, Zero Bevel and Hypoid Gears up to 500mm in diameter and 12 mm in module. The machine is most suitutable for batch production or mass production of driving pinions of gear pairs used in cars, light and medium-sized trucks and construction machineries.

2. Main Features and Structural Characteristics of Machine

1. The machine is designed to operate as a three axes CNC control Spiral Bevel Gear Generator, i.e. cradle oscillation (X axis), work spindle rotation (Y axis) and sliding base movement (Z axis). Each of three axes will be separately or simultaneously controlled. The rotation of cutter spindle (S axis) is controlled by an AC frequency variable motor for its stepless control.

2. A high precision dual-leads worm gear set is used for cradle drive and work spindle drive respectively, and many measures are adopted for improving the structural and driving rigidity of machine, so as to ensure the machining accuracy, productivity and operating lifes.

3. A cutter tilt mechanism with maximum tilt angle 30°is designed for the cutter spindle for cutting the pinions to mesh with non-generated gears (minimum gear ratio 2.5:1) and getting better tooth bearing correction.

4. There are no any change gears on the machine for minimizing the setting time of machine.

5. The feeds of machine are controlled by CNC programme, so as to simplify the operation and increase the cutting efficiency.

6. CNC control system, main electrical and hydraulic components, critical bearings and sealings are fine quality imports, which guarantee the machine reliability.

7. The machine is equipped with an independent sealed electrical cabinet, which is with air conditioner or thermo exchanger.

8. Safety guards and auto-chip conveyor can be provided on the machine.
