What are the similarities and differences between the standard gear and the gear?
The process and method of processing are exactly the same. The gear has changed, and the outer circle has changed. The distance between the tool axis and the gear center must have changed. But it doesn't seem to matter to the process. When processing, or first with the hob gently touch the outer circle, and then into three points, two standard teeth deep, roll over the hob centerline, and then measured public law line, and then enough teeth depth. So, but from the processing method, exactly the same.
Keep away from the gear at a distance (or shift), or a short distance from the gear (negative displacement). Everything else is the same.
Just a little different. When machining the variable gears, the axis of the gear cutter is more than that of the standard gear
