The working principle of a gear CNC gear hobbing machine: When the pump is started, the driving wheel drives the driven gear, which rotates in the opposite direction. There is good meshing between the gear and the gear. The teeth of the two gears scrape away some of the oil at the inlet, forming a low-pressure suction liquid that enters the pump body and is divided into two paths. The liquid is pushed forward by the gear in the gap between the gear and the pump casing, and is pressed to the oil outlet to form a high-pressure discharge. The main equipment of the blowing air recovery boiler includes: combustion furnace, CNC gear hobbing machine, steam superheater, boiler body, second air preheater, soft water heater, first air preheater, induced draft fan, and forced draft fan.

Selection of CNC gear hobbing machine hobs

The selection of gear hob accuracy level should be based on the accuracy level or process requirements of the processed gear.

2. Selection of the number of gear hob heads. When precision machining with CNC gear hobbing machines, in order to improve machining accuracy, single head hobs should be selected. When rough machining, in order to improve machining efficiency, multi head hobs should be selected.

3. Selection of spiral direction for gear hobs. When hobbing straight cylindrical gears, right-handed hobs are generally used. When CNC hobbing machines are used to cut helical cylindrical gears, the spiral direction of the hob should be the same as the working direction. That is to say, right-hand helical gears should use stone cutters, while left-hand helical gears should use left-hand cutters.

4. Select according to process requirements. For example, for CNC gear hobbing machines that require gear grinding after gear hobbing, a torsional grinding roller must be selected. For those that require gear shaving after gear hobbing, a retained shaving roller (also known as a pre shaving roller) should be selected.
