How to Deal with Bean Processing Equipment Wheel Gear Abrasion

How to deal with bean processing equipment wheel gear abrasion? Bean processing equipment wheel gear may have different degrees of abrasion. Abrasion can be divided into mild abrasion, medium degree abrasion, serious abrasion, abrasive particle abrasion and corrosion wear.
 

The features of mild abrasion: it is very slow and even. After abrasion, the tooth surface is flat and bright. Contact tooth surface coarseness, the lubrication oil viscosity, tooth surface working speed, mismatching between working load can cause mild abrasion. All of the reasons make the tooth surface have no enough lubrication oil film thickness, which causes the tooth surface micro-bulge peak to be ground or pressed. After wheel gear polishing, we can adopt high-viscosity lubrication oil to form proper lubrication oil film thickness and this cannot affect the wheel gear service life and performance.
 

Medium grade of abrasion can be prevented by improving lubrication conditions and increasing oil film thickness.
 

Serious abrasion makes the wheel gear surface ground and the tooth shape damaged and the wheel gear service life reduced. Serious abrasion is caused by the bad lubrication system and sealing device. We can adopt proper sealing form and lubrication device, improve the working speed, reduce vibration load and change the wheel gear geometrical parameter, material, precision and tooth surface coarseness.
 

We can reduce the abrasive particle abrasion by improving the tooth surface hardness and finish degree, reducing the tooth surface sliding rate, choosing suitable lubrication method and keeping lubrication oil clean.
