Description melt pump gears
Melt pump gear common with straight teeth, helical, herringbone gear, helical gear, involute tooth profile of the main types of lines and arcs.
Gear pumps are usually small and more involute spur gears, gear pumps often used high-temperature shifted gears, transmission of high viscosity, high-pressure melt the polymer melt pump to use more involute helical gears.
Gear formed integrally with the shaft, its rigidity and reliability of the shaft above the gear pump gears made separately. Low-pressure gear pump gear often use a square structure, namely the gear tooth width equal to the tip diameter.
High viscosity and high pressures using a pump gear teeth of a width less than the diameter of the addendum circle, which is to reduce the radial pressure receiving area of ??the gear, the gear to reduce the bearing load.
Stainless steel melt pump is a new type of transmission fluid machinery, has a simple structure, safe and reliable, easy maintenance, the liquid continuous uniform, stable pressure.
