Customized 20Cr2Ni4 Forging Alloy Steel 12 Module Spur Gear For Mining Machinery
Material: 20Cr2Ni4 Steel
Foring Steel with UT Inspection.
Gear teeth profile grinding.
Designed for heavy duty mining machinery.
Spur gear is the most common type of gear.
It is easier to manufacture and the cost is lower compared with the spiral bevel gears.
Spur gears are typically used for lower speed applications, although they can be used at nearly any speed.
Spur gears only produce radial forces (no axial forces), but the method of tooth meshing causes steep stress
on the gear teeth and excessive noise production.
