Description
The gears of our JZQ cylindrical gear reducer are carburized, hardened and ground, have high loading capacity and low noise. It is mainly used for belt conveyors and various transportation machines, and is also used for driving other general-purpose machines. It has the advantages of high loading capacity, long service life, small volume, high efficiency, light weight, etc., and is installed vertically in the drive for the input and output shafts.
Gears and shafts as important parts in a JZQ gearbox, we adopt carbon steel material. Carbon steel has features of high strength and good plastic toughness. Its strength is 25%-50% higher than ordinary steel, its elongation is 15%-23%, and its impact toughness is higher than 60J/CM2 at room temperature. High-quality accessories ensure the gearbox with the advantages of good performance, smooth and burr-free. Our thickened housing adopts advanced grinding process, ensuring the surface smooth and houisng more durable, also the sealing performance is great, it is sturdy and corrosion-resistant.
