More than one third of the gear transmission noise of the melt gear pump is caused by burrs and bumps, which is also a difficult problem to eradicate. Some manufacturers of melt gear pump engage a pair of gears on the noise checking machine before assembling the gear box to remove burrs and bumps, which is a very passive method. The manufacturers of Bart melt gear pump consider that it is reasonable to adopt the following measures: 1. After cutting the teeth, all the gears are transported by the station.
2. For gear shaft parts, the hobbing part is immediately covered with plastic pipes and then transferred to the next process, with plastic delivery.
3. Cyanide parts are treated by liquid sandblasting after heat treatment.
4. Cyanide gear honing process.
