What are the causes of Vertical roller mill gear damage?

1. Because the transmission form of Vertical roller mill is rigid connection, the asynchronous motor is known rigidly through the elastic coupling and the gear shaft. It is easy to cause the damage of the big and small gears when the equipment has been iron or overloaded. In addition, bad gear engagement is also one of the important reasons for the damage of Vertical roller mill gear. This is because, in the case of poor gear engagement, the clearance between the tooth side and the top of the tooth is not within the prescribed range, resulting in the gear damage in a short time.

 

2. When Vertical roller mill crushes the material, there are some unbreakable materials in the crushing chamber, such as iron impurities, which will cause greater wear and tear to the parts during the crushing process, especially to the gear. At the same time, if Vertical roller mill is in overload operation for a long time, the crushed material will have a greater impact on the equipment, and can not take appropriate protective measures, it will cause serious wear and tear gear.

 

3, reasonable lubrication and maintenance work is an important factor to prevent the damage of dolomite gear. Because, in the long running process of Vertical roller mill, if the lubricant is insufficient, or if the lubricant changes qualitatively, it will affect the lubrication of the gear, thus aggravating the gear damage. In the crushing production line, it is inevitable that impurities will cause certain pollution to the gears, which will affect the operation of the equipment and the meshing between the gears, and then lead to the damage of the gears.
