Spur Gears Wholesale Price Failure Form
Time:
2022-06-30
Spur Gears Wholesale Price under load in operation engineering, like a cantilever beam, when its root is subjected to pulsed cyclic stress exceeding the fatigue of Spur Gears Wholesale Price material, cracks will occur at the root and gradually expand, when the remaining part cannot withstand the transmission. Broken teeth will occur under load.
Do you understand the failure form of Spur Gears Wholesale Price? Let’s take a look at it briefly below!
1. Broken gear teeth
Spur Gears Wholesale Price under load in operation engineering, like a cantilever beam, when its root is subjected to pulsed cyclic stress exceeding the fatigue of Spur Gears Wholesale Price material, cracks will occur at the root and gradually expand, when the remaining part cannot withstand the transmission. Broken teeth will occur under load. Spur Gears Wholesale Price can also cause broken teeth due to severe shocks, eccentric loads and uneven material in the job.
2. Fatigue pitting
When the two gear teeth meshing with each other are in contact, the force and reaction force between the tooth surfaces cause contact stress on the two working surfaces. Since the position of the meshing point changes, and Spur Gears Wholesale Price is doing periodic motion, so The contact stress varies according to the pulsation cycle. Under the action of this alternating contact stress on the tooth surface for a long time, small cracks will appear at the tool marks of the tooth surface. As time goes on, the cracks gradually expand laterally on the surface layer. The surface of the tooth produces a small area of spalling and some fatigue craters are formed.
3. Plastic deformation of tooth surface
Under impact load or heavy load, the tooth surface is prone to local plastic deformation, so that the curved surface of the involute tooth profile is deformed.
