quiet running of the variable speed electric motor

The variable speed electric motor meshing of gears is tight to reduce noise and increase strength. A close meshing also slows down the heating of the helical gear reducer, and lengthens gear life.
In transmission, the multi-tooth meshing achieves a smooth, reliable, and quiet running of the helical gearbox.
The variable speed reducer housing is made with aluminum die casting. The adoption of new machining technology improves the precision of workpieces.
The gears are made of high quality alloy steel, with the surface hardened by carburizing and quenching treatments. The teeth are made by fine grinding process. So as a whole, the helical geared motor is excellent in performance.
