Gear Hobbing Machine Description


CNC gear hobbing machine is suitable for batch, small batch and single piece production and processing of cylindrical gears and worm gears, as well as drum gears with certain parameters. Spline hobs can also be used for continuous indexing and hobbing of short spline shafts with 6 teeth and more with a length of less than 300. And the sprocket hob can be used to roll and cut the sprocket. When machining cylindrical gears, reverse milling and forward milling and hobbing can be adopted, and the full tooth width can be machined by axial feed (vertical feed). NC Hobbing Machine hobbing ordinary worm gear is processed by radial feed method. The adjustment and machining method of the CNC hobbing machine when machining the spline shaft and sprocket is the same as that when machining the cylindrical spur gear.

Working principle of CNC gear hobbing machine: when the pump is started, the driving wheel drives the driven gear, and the driven gear rotates in the opposite direction. There is good meshing between the gear and the gear. The teeth of the two gears scrape away some oil at the inlet, so it forms a low-pressure suction liquid. The liquid entering the pump body is divided into two ways, which is pushed forward by the gear in the gap between the gear and the pump housing, The pressure is sent to the oil drain to form high pressure and drain the liquid. The main equipment of blowing gas recovery boiler include: combustion furnace, CNC gear hobbing machine, steam superheater, boiler body, second air preheater, soft water heater, air preheater, induced draft fan and forced draft fan.

Selection of hob for NC gear hobbing machine:

1. The accuracy grade of gear hob shall be selected according to the accuracy grade or process requirements of the processed gear.

2. Selection of gear hob head number. In order to improve the machining accuracy, single head hob should be selected during finishing machining of NC gear hobbing machine. In order to improve the machining efficiency, multi head hob should be selected during rough machining.

3. Selection of helical direction of gear hob. When hobbing spur gears, right-handed hobs are generally used. When the CNC hobbing machine Hobbes helical cylindrical gears, the spiral direction of the hob should be the same as that of the work. Stone rotary hob shall be used for right-hand helical gear, and left-hand hob shall be used for left-hand helical gear.

4. Select according to the process requirements. For example, for CNC gear hobbing machine, twist grinding hob shall be selected for gear grinding after gear hobbing, and shaving hob shall be selected for gear shaving after gear hobbing.
