Effective Method of Reducing Transmission Noise of Melt Gear Pump

 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 pumps engage a pair of gears on the noise checking machine before assembling the gearbox to remove burrs and bumps, which is a very passive method. Butt melt gear pump manufacturers believe that the following measures are more reasonable:

1. After cutting the teeth, the workstation is used for transshipment.

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.
