　　The bevel gear is an important driving part of the cone crusher, and its operation directly affects the over reliability of the crusher. The bevel gear of the cone crusher is seriously worn. Below we analyze the reasons for the wear of the bevel gear.

　　1. The grinding coefficient of the crushed material is large. If the grinding coefficient of the material to be crushed is large and the impact on the bevel gear is large, the crusher will easily cause serious wear or breakage of the bevel gear teeth under long-term overload operation.

　　2. Impurities in bevel gears

　　In cone crusher work, the gears need tight consistency. If impurities get in, the friction of the bevel gear will increase, causing wear and damage.

　　3. Poor lubrication of bevel gears

　　Good lubrication conditions are one of the * ways to prevent the wear of various parts of the crusher. If the quality of the lubricating oil of the gear is unqualified and the lubrication method is incorrect, the lubrication conditions of the gear will be damaged and the wear will be aggravated.

　　4. Inappropriate fit of bevel gears

　　Poor gear meshing is also an important reason for the damage of cone crusher bevel gears. If the gear mesh is poor, the clearance between the tooth side and the tooth tip will not be within the specified range, which will cause the gear to be damaged in a short time.

　　5. Improper device transmission method

　　The transmission form of the cone crusher is rigid connection. The motor is connected with the gear shaft through an elastic coupling. When the cone crusher has an iron or works with overload, it is easy to cause damage to the large and sm gears.

　　6. Unbreakable foreign objects enter the crusher

　　If the cone crusher gets into iron lumps and other unbroken foreign objects, it is easy to cause damage to the machine parts when the iron passing device fails, especi y the gears.
