Due to different gear conditions, different materials and different environmental conditions, the causes of gear damage and failure are often complicated, but they can be analyzed and searched from the following aspects.
1. Design errors of geared motors
2. Errors in material and hot working.
3. Errors in machining.
4. A mistake in assembly.
5. Mistakes in use and maintenance.
