Rolling test of bevel gear pairs is an important operation during the cutting of bevel gears for checking the tooth contact pattern, running noise and engaging backlash and it is also the important basis for readjusting the parameters for the gear cutting machines.
According to the requests of the endusers in the automobile and the earth-moving machinery industries, Model YK9550 CNC Hypoid Tester has been successfully developed along with the develvpment of CNC techniques.
This machine is designed to test gear pairs of right-angle straight bevel gears, spiral bevel gears and hypoid gears of work diameters up to 500mm.
The main features of the machine are:
1. The driving headstock is driven by a servo motor and a high- precision ball lead screw. Automatic feeding can be realized, the pre-set backlash can be kept repeatedly and the tooth can be set automatically.
2. The driving spindle adopts frequency variable speed regulation, ranging from 700~2000 rpm stepless speed regulation, and the rotation direction of the spindle can be changed automatically.
3. The structure of the driving headstock uses a buffering device and has a sliding hydraulic chucking function, so the structure rigidity is high.
4. The driven headstock adopts a suspensible frame structure, increasing the structural rigidity and ensuring the stability of the engaging position of the gears to be checked.
5. The driven spindle adopts the loading made of electrohydraulic proportion control. Automatic pre-set loading with a display function can be realized.
6. The machine is equipped with SIEMENS 802D CNC control system.
7. The machine is equipped with a sealed electrical cabinet,in which a thermo exchanger or an air
conditioner may be adopted(option).
8．The hydranlic pump station is located at the side of machine.
This machine is specially suitable for mass production of bevel gears and the structure performance increases tremendously the stability and the reliability of the testing results.
