Background

Two coaxial gears separated by a certain distance are integrated into a whole, namely a duplicate gear which is mostly used as a sliding gear of a gearbox. The gear shaping process of the dual gear is generally big end gear hobbing and small end gear shaping.

As the main cutting motion of gear shaping processing is that a gear shaping cutter is driven by a main shaft of the gear shaping machine to do up-and-down reciprocating motion vertical to the end surface of a pinion, burrs and iron cuts are generated on a cutter slot of the gear, namely the lower end surface of the processed pinion, of the gear subjected to gear shaping processing by the gear shaping cutter. Because the clearance groove is narrow, burrs generated by the reciprocating motion of the cutter during gear machining are accumulated in the clearance groove and are difficult to discharge, and the burrs collide with the reciprocating pinion cutter to cause cutter hitting or aggravate cutter abrasion, so that the burr removal is also a key link of gear machining. Generally, after the gear shaping process is finished, the turning process is carried out, and burrs adhered to the end surfaces of the gears between the empty slots of the double-tooth are turned and removed by a lathe.
