Introduction of Coal Shearer Accessories Gears
The gear is a raised portions of each gear for meshing,these raised portions are generally arranged in a radial pattern, and the gear teeth on the paired gears are in contact with each other, so that the gears can continue to mesh and operate.
The category of Coal Shearer Accessories Gears
According to the specifications or size classification, gear models are divided into standard and non-standard two; according to different domestic and foreign units of measurement, the gear model is divided into metric and imperial.
The Materials of Coal Shearer Accessories Gears
The commonly used steels for making gears are quenched and tempered steels, hardened steels, carburized and quenched steels, and nitrided steels. The strength of cast steel is slightly lower than that of forged steel, and is often used for gears with larger dimensions. The mechanical properties of gray cast iron are poor and can be used in open gear transmissions with light loads. Ductile iron can partially replace steel-made gears; plastic gears have many uses. In places with light load and low noise requirements, gears paired with them are generally made of steel gears with good thermal conductivity.
