Causes And Tips for Cone Crusher Bevel Gear Wear

The cone crusher is a kind of commonly used mining crushing equipment, bevel gear is an important transmission component of the cone crusher, and its operation condition directly affects the overall reliability of the crusher. In actual production, bevel gear wear problems occur from time to time, seriously affecting the normal operation of the equipment and production efficiency. Today we will analyze the reasons for cone bevel gear wear and effective preventive measures.

Cause For Cone Crusher Bevel Gear Wear

1. The material to be crushed has a large coefficient of abrasion
   If the material to be crushed has a large coefficient of abrasion, and the impact on the bevel gear is large, the crusher will easily cause serious wear and tear or even fracture of the bevel gear teeth under prolonged overload operation.
2. Impurities in the bevel gear
   In the cone crusher operation, the gears need to be close together. If impurities enter the bevel gear, friction will increase, resulting in wear and damage.
3. Bevel gear material
   The material of the gear directly affects its wear resistance. Gears made of higher hardness and toughness generally have better wear resistance, reducing wear.
4. Poor lubrication conditions of bevel gears
   The advantages and disadvantages of lubrication conditions directly affect the friction coefficient between gears. Good lubrication condition is one of the effective ways to prevent the wear of all parts of the crusher. If the lubricant quality of the gear is not qualified, the lubrication method is not correct, etc., it will destroy the lubrication condition of the gears and aggravate the wear.
5. It is not suitable for the bevel gears to mesh.
   Poor gear mesh is also an important cause of cone breakers’ cone tooth damage. When the gear mesh is bad, it leads to tooth side clearance and tooth top clearance not being in the prescribed range, which damages the gear quickly.
6. The crusher into the non-crushable foreign objects
   If the cone crusher into the iron and other non-crushable foreign objects, the failure of the iron device can easily lead to damage to machine parts, especially on the gear is more harmful.
7. Loose equipment
   Loose equipment will lead to increased friction between the large and small bevel gears, accelerating wear.
8. Improper equipment transmission
   The cone crusher’s transmission form is a rigid connection. The motor is rigidly connected to the gear shaft through a flexible coupling. When the cone crusher is in over-iron or overload operation, damage to the large and small gears is easy.
9. Cone crusher use environment
   The production environment of mining, metallurgy, and other industries is often harsh, and the air contains a lot of dust and harmful gases. These substances will adhere to the surface of the gears, aggravating the wear and tear of the gears.

Tips to Reduce Wear of Cone Crusher Bevel Gear

1. Selection of suitable gear materials
   According to the use of the gear environment and requirements, choose a better wear-resistant performance of the material made of gear, such as high hardness steel, stainless steel, and so on.
2. Prohibit the equipment from overloading
   If too much material is put into the crushing cavity of the cone crusher and the equipment is in overloaded operation for a long time, it will not only fail to improve the production capacity, but on the contrary, it will also cause serious wear and tear or even fracture of the gears or lead to localized fatigue cracks on the tooth roots, etc. Therefore, we have to pay attention to make the equipment work and rest. Therefore, we should pay attention to the combination of labor and leisure equipment to reduce gear damage.
3. Strictly control the feeding material
   If the material put into the crushing cavity contains iron and other impurities, it will cause serious damage to the gears, so we must strictly control the feed in production to minimize the damage to the gears.
4. Eliminate additional wear
   As the gear is in the operation process, it is easy to produce impact vibration and additional sliding wear, resulting in serious damage to the gear. So we can make the large bevel gear center hole and eccentric bushing center line deviation of a distance, to ensure that the large bevel gear is always rotating around the fixed center line of the equipment, thus eliminating the additional shock vibration and additional sliding wear, to reduce gear damage.
5. Ensure good lubrication conditions
   Regularly check the lubrication system to ensure the quality and quantity of lubricant and maintain good lubrication conditions. At the same time, pay attention to the regular replacement of lubricating oil to avoid impurities in the lubricating oil on the gear wear.
6. Ensure the normal meshing of gears
   If the gears of the cone crusher do not mesh properly in production, it will make the gears damaged faster. Therefore, we should ensure the normal meshing of gears, so that the cone tops of the two gears intersect at one point, and the pitch circle overlap.
7. Do a good job of gear maintenance
   Do a good job of gear maintenance, mainly the following two points: One is to ensure that the lubrication of the gear, reduces the wear and tear of the gear operation; The second is to pay attention to checking whether there is debris between the gears, if there is debris should be cleaned up promptly, so as not to affect the meshing of the gears, and to reduce the damage to the cone crusher gears.
8. Regularly check the equipment
   Regularly check and tighten the key bolts, connectors, and parts on the equipment to ensure the tightness and stability of the equipment. Timely find and deal with the loosening phenomenon of the equipment to avoid increasing friction.
9. Improve the use of the environment
   Minimize dust and harmful gas emissions from the production site to improve the working environment. For dust and harmful gases that can not be avoided, take appropriate protective measures, such as installing dust removal equipment, ventilation equipment, etc.

Through the above introduction of common causes, preventive measures and techniques of cone gear wear in cone breakers, home for cone crusher gear wear causes and avoidance measures also have a lot of understanding. Cone crusher is a very good product, which brings a lot of help for our work. In the work of the cone crusher, it is necessary to prevent excessive iron and ensure good lubrication of the equipment. In addition, when replacing the large and small bevel gears, pay attention to the screening of manufacturers, choose gears with high processing precision, and pay attention to the selection of suitable meshing gap when installing, to avoid the possibility of tooth hitting and root cutting from the source, and to ensure the efficient operation of the equipment to improve the production efficiency.
