Question

write down six major cause of gear jam​

Answer 1

Answer:

. Moderate wear: This type of where leaves contacts patterns that show the metal has been affected in the addendum and the dedendum area. Issues with inadequate lubrication commonly cause it, but it may also be due to contamination in the lubrication as well.

2. Excessive wear: This is wear that has continued to be a problem until a significant amount of material has been affected on the surfaces. You may see pitting on the surface with excessive wear, typically caused by not seeing the first wear early enough, and it continues to progress.

. Abrasive wear: In gears that are showing signs of abrasive wear, it may appear as radial scratch marks, grooves or some other identifier that would show contact is a problem. One of the most common reasons why abrasive wear takes place is due to foreign bodies in the lubrication. This issue could include metallic debris from the bearings or gear system, rust, sand or weld spatter. It is common in new systems before the filter can clean the system.

4. Corrosive Wear: Chemical action deteriorates the surface of the gear, such as through acid, additives or moisture in the lubrication oil. As the oil breaks down, the chemicals that exist in the lubricant attack the surfaces. It tends to result in uniform, fine pitting on the two surfaces.

5. Frosting: This issue usually shows up in the dedendum area of the driving gear. The wear pattern gives a frosted appearance, which are many micro pits on the surface. Frosting is a common issue when the heat breaks down the lubrication film.

6. Spalling: Although it is similar to severe pitting, the pits tend to be shallow and larger in diameter. Additionally, the area that is showing spalling does not tend to be uniform. It is a common problem when high contact stress exists.
