Causes of Worn Bevel Gear of Conical Crusher

In the cone crusher, a large gear and a small gear constitute an important structure that changes the transmission direction to transmit the cone crushing torque. The operating condition of the bevel gear directly affects the overall operation of the crusher. However, in the long-term overload operation, the bevel gear may crack and wear. Once it breaks, it will directly affect the overall reliability of the crusher. Here we mainly analyze the causes of bevel gear wear.

1. The crushed material has a difficult to grind coefficient. If the material to be crushed has a large abrasion coefficient and a large impact on the bevel gear, the crusher can easily cause severe wear and fracture of the bevel gear teeth under long-term overload operation.

2. There are impurities in the bevel gear. In the cone breaking operation, the gears need to be closely matched. If impurities are entered, the friction of the bevel gear will increase, causing wear and damage.

3. The lubrication of the bevel gear is not good. Good lubrication conditions are one of the effective methods to prevent the wear and tear of all parts of the crusher. If the quality of the gear oil is not qualified, the lubrication method is not correct, etc., it will destroy the lubrication of the gear and increase the wear.

4. The anastomosis degree of the cone broken bevel gear is not suitable. Poor gear meshing is also an important reason for the damage of conical broken cone teeth, because when the gear mesh is not good, the tooth side clearance and the tooth top clearance are not within the specified range, which will cause the gear to be damaged in a short time.

5. Unbreakable foreign matter enters the crusher. If the cone crusher enters unbreakable foreign bodies such as iron blocks, the failure of the iron-passing device can easily cause damage to the machine parts, especially the damage to the gear.
