 1) Extremely shorten the main motion transmission chain
 From main motor D 1 To the tool spindle C, which is the main motion transmission chain, Figure 5 A pair of reduction gears, tool spindle reduction driven gear 10 and tool spindle reduction driving gear 11 are used, and the speed ratio is 18 / 85. Main motor D 1 Choose 4-pole, synchronous speed 1500 rpm, adopt frequency conversion speed adjustment, adjust from 1000 rpm to 2000 rpm, the diameter of hardened gear hob is 300 mm, and the guaranteed cutting speed is 200 m / min to 400 m / Minute.
 2) Adopt horizontal structure
 The workpiece spindle A adopts the horizontal type, the column is eliminated, and the tool post is fed in the horizontal direction, which reduces the center of gravity of the machine tool and improves the static rigidity of the machine tool.
 3) Use flat worm wheel 8 and flat enveloping worm 9 as machine tool indexing mechanism

 In this embodiment, electric shaft transmission is used to replace high-speed transmission elements. The specific implementation scheme is: Image 6 Main motor in D 1 And work spindle drive motor D 2 Synchronous motors with the same synchronous speed are used. The two motors are like a shaft, with gears 12, 13, 14, 15, 16, 17, 18, 19 and the long spline shaft 30 eliminated in the middle.
 Since the main motor D 1 Drive motor D with workpiece spindle 2 Like a shaft, the index change wheel i x , Differential change gear i y And feed changer i s The application calculation formula is the same as the first embodiment of the hardened gear hobbing machine.
 This embodiment uses two AC synchronous motors instead of mechanical transmission. From the theoretical analysis: when the external power supply voltage and processing load fluctuate, it will affect the synchronization characteristics of the motor, thereby affecting the processing accuracy o...
