Information

The OEM Sprockets company is a wheel with cog-type sprocket teeth that meshes with a block of precise pitch on a link or cable. It is widely used in mechanical transmission in chemical, textile machinery, escalator, wood processing, agricultural machinery, food processing, instrumentation, petroleum and other industries. So what are the reasons for its wear? Let’s follow the editor to understand it briefly!
1. The greater the adhesive wear load and the higher the surface temperature, the more serious the adhesion phenomenon. For metal materials with a certain hardness, wear tests are performed under different pressures to obtain a graph of the relationship between wear rate and pressure. When the pressure reaches more than 1/3 of the hardness of the material, severe wear will occur. According to the stress distribution diagram, it can be seen that the contact point of greater stress is the greater pressure, and its value is 884.4 MPa. Because the quenching hardness of the chain socket is HRC48-52, the corresponding hardness value is 4800MPa. Therefore, the pressure is far less than 1/3 of the material's hardness, so adhesive wear is not the main form of OEM Sprockets company wear.
2. Contact fatigue wear. OEM Sprockets company and the chain friction pair are alternating contact stresses, which are prone to fatigue pitting on the friction surface. The index for judging the contact fatigue strength of metals is the upper limit of contact fatigue, that is, the larger stress that does not cause pitting corrosion under a certain number of stress cycles. The upper limit of contact fatigue of 40Cr is σ0H=HRC17 +200 after surface quenching treatment, and σ0H=1016MPa is calculated. According to the stress distribution diagram, the larger stress value of the chain socket of the OEM Sprockets company is 884.4 MPa. Its value is very close to the upper limit of contact fatigue allowed by the OEM Sprockets company surface, and it is easier to cause pitting failure at higher stress. However, due to the poor lubrication conditions between the OEM Sprockets company and the chain, pitting corrosion was too late to form and has caused wear. At this time, the main form of damage is wear rather than pitting. Contact fatigue wear is the main form of wear of the OEM Sprockets company, and it basically determines the service life of the OEM Sprockets company.
The above is an introduction about the reasons for its wear. I hope you can learn more about it through the introduction of the above editor.
