Products Description
Gearbox is a widely used device in mechanical transmission system, which can transfer the power signal from the power source to the load side to achieve the purpose of speed change, steering or torque increase. And gear box castings are an indispensable part of the gear box.
(1) Types of gearbox castings:
Gears: gears are one of the most common castings in gearboxes. Gears used in gearboxes are usually made of alloy cast steel or flanged ductile iron materials. The types of gear castings mainly include helical gears, spur gears, bevel gears, worm gears and planetary gears.
Bearings: Bearings in gearboxes are used to support the shaft and reduce friction and wear. Common bearing castings include rolling bearings, plain bearings and meet bearings. Bearing castings are usually made of materials such as ductile cast iron and copper casting.
Sprocket: sprocket is one of the common castings in gearboxes, its main function is to connect the chain and other components in the mechanical transmission system to realize signal transmission and load rotation. The types of sprocket castings include single sprocket, double sprocket and composite sprocket.
Pump Wheel: Pump wheel is a casting used for transmission of liquid medium in gear box, and its types are many, such as impeller pump, centrifugal pump, etc.. Usually made of ductile cast iron or alloy cast steel materials.
(2) gear box castings application areas
Gearbox castings are widely used in mining, dock handling machinery, petrochemical, construction machinery and metallurgical machinery and other fields. Its application in these fields is very important to provide reliable power support for mechanical transmission system.
(3) Analysis of the advantages and disadvantages of gearbox castings
In terms of material selection for gearbox castings, alloy cast steel has the advantages of high strength, high toughness, wear resistance and corrosion resistance, but the cost is relatively high. Ductile cast iron, on the other hand, has advantages such as low cost, high strength and toughness, but its corrosion resistance is low. In the process of material selection, it is necessary to consider the working environment, working conditions and cost and other factors.
