Cone crusher bevel gear wear seriously? 6 reasons and 5 ways to be productive!

Bevel gear is an important driving part of cone crusher.

Causes of bevel gear wear

1. The grinding coefficient of crushed materials is large

If the grinding coefficient of materials to be broken is large, the impact on bevel gear is large, then the crusher in the long time overload operation, it is easy to cause serious wear or even fracture of cone gear teeth.

2. There are impurities in bevel gear

In the cone broken operation, the gear needs a strict degree of anastomosis, if into the impurities, will cause increased friction bevel gear, causing wear and damage.

3, bevel gear lubrication is not good

Good lubrication condition is one of the effective ways to prevent the crusher from wearing all the parts. If the lubricating oil quality of the gear is not qualified, the lubrication mode is not correct, will damage the lubrication condition of the gear, aggravate the wear.

4, bevel gear fit is not suitable

Poor gear mesh is also an important reason for the damage of broken conical teeth, because when the gear mesh is not good, the tooth side clearance and tooth top clearance are not in the specified range, which will cause the damage of the gear in a short time.

5, into the crusher can not break foreign bodies

If the cone crusher enters the iron block and other unbreakable foreign matter, the failure of the overiron device will easily lead to the damage of machine parts, especially the greater harm to the gear.

6. Improper transmission mode of equipment

The transmission form of cone crusher is rigid connection. The motor is rigidly connected with the gear shaft through the elastic coupling. When the cone crusher runs over iron or overload, it is easy to cause damage to the gears.

Preventive measures to reduce wear and tear

Face the wear and tear of bevel gear, what measures should be taken to prevent it?

1. Overload of equipment is prohibited

If too many materials are put into the broken cavity of the cone, the equipment will be overloaded for a long time, which will not only fail to improve the production capacity, but also cause serious wear and even fracture of the gear, or lead to local fatigue cracks in the tooth root. Therefore, we should pay attention to the combination of labor and leisure equipment, reduce the damage of gear.

2. Strictly control incoming materials

If the material in the crushing cavity contains iron and other impurities, it will cause serious damage to the gear. Therefore, we must strictly control the material in the production to reduce the damage of the gear.

3, eliminate additional wear

Because the gear is easy to produce shock vibration and additional sliding wear during operation, the gear is seriously damaged. Therefore, we can make the center hole of the large bevel gear deviate from the center line of the eccentric shaft sleeve by a distance, so as to ensure that the large bevel gear always rotates around the fixed center line of the equipment, thus eliminating the additional shock vibration and additional sliding wear, so as to reduce the damage of the gear.

4. Ensure the normal engagement of gears

If the cone crusher gear meshes improperly in production, will make the gear damage faster. Therefore, we should ensure the normal engagement of the gears, so that the cone tip of the two gears meet at a point, and the pitch circle coincide.

5, do a good job of gear maintenance

To do a good job in gear maintenance, there are mainly the following two points:

One is to ensure the lubrication of gear, reduce wear in gear operation;

Two is to pay attention to check whether there are sundry inclusions between the gears, if there are sundry to clean up in time, so as not to affect the gear mesh, reduce the damage of cone crusher gear.
