YKD2250A CNC Spiral Bevel Gear Generator
YKD2250A CNC Spiral Bevel Gear Generator
YKD2250A CNC SPIRAL BEVEL GEAR GENERATOR
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.
