The specific processing method of helical gear

The specific processing method of helical gear

Answer:

1. With the appropriate gear, according to the modulus calculation! 2. Install the normal displacement angle of 20 ° 22 'hob. This step need to pay attention to, if there is no such forming helical gear hob, you can also release
To roll the helical gear on the hobbing machine, first of all, you have to be clear that the cylindrical angle of the cylindrical angle is 20 ° 22 '. It is simpler to do this on a hobbing machine than to do it on a universal milling machine.
Hobbing machine head of the universal head set screws, the nose rotation 20 ° 22 'to complete the work.Note that the angle adjustment is completed, you must lock the head before you can start rolling work! 3. The gear blank
Installed on the mandrel of the turbine and calibrated its turbine concentricity with a dial indicator. 4. Tighten the blank fixing bolts and start rolling. 5. After the first lap is rolled up, stop the machine and carefully check the roll out
