The wear of planetary reducer gear is the friction loss of materials on the gear contact surface. The wear modes of planetary reducer gear mainly include the following forms:

1. Slight wear: slight wear is a very slow wear phenomenon caused by the mutual contact between metals during operation.

2. Moderate wear: moderate wear is generally caused by a small amount of lubricating oil (grease), and the thickness of the oil film is too thin for the load. It may also be caused by contaminated impurities in the lubrication system. Many gear drive designs operate in this situation.

3. Excessive wear: excessive wear is moderate wear in development, when a certain amount of material from the tooth surface, and then to the excessive wear stage. There are obvious dents near the pitch line.

4. Abrasive wear: in abrasive wear, the contact surface will have complete circular radial scratches or grooves. Impurities entering the external lubrication system will cause wear.

5. Corrosion wear: corrosion wear is the wear of tooth surface caused by chemical composition, which can be caused by the active material components in lubricating oil.

6. Gluing: the result that the oil film between the tooth surfaces disappears due to the local overheating of the meshing gear and the direct metal contact and wear of the two tooth surfaces.

7. Dull: the dull surface of teeth is generally caused by the heat generated by meshing caused by poor lubrication. Heating due to poor lubrication. Due to the heat generated by meshing and most of the heat generated by rotating gears, the film thickness becomes thinner.

8. Moderate gluing: moderate gluing indicates a typical gear wear pattern, usually at the top or root of the teeth or both. Lubrication failure is usually caused by overheating of engagement.

9 destructive gluing destructive gluing is a kind of gear failure with obvious buckle and tear groove marks along the sliding direction. It is generally caused by overheating due to insufficient lubrication, high working temperature, high tooth contact stress or speed.

10. Local gluing: local gluing occurs in the local area of the contact tooth surface, which is generally the result of the main concentration of local load caused by improper design methods.

11. Interference between tooth top and tooth root: it is a kind of gluing. The teeth near the tooth root fall off obviously, and destructive radial scratches often appear.
