Cone Crusher Maintenance Recommendations

The bevel gear is an important transmission component of the cone crusher, and its operation directly affects the overall reliability of the crusher. Recently, a user commented that the bevel gear of the cone crusher had serious wear and tear, and asked what to do. This article mainly analyzes the causes and preventive measures of the bevel gear wear of the cone crusher.

Causes Of Bevel Gear Wear

1. The Hard-To-Grind Coefficient Of The Broken Material Is Large

If the hard-to-wear coefficient of the material to be crushed is large and the impact on the bevel gear is large, the cone crusher can easily cause severe wear or even breakage of the cone teeth under long-time overload operation.

2. There Are Impurities In The Bevel Gear

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

3, The Lubrication Condition Of The Bevel Gear Is Not Good

Good lubrication conditions are one of the effective methods to prevent the wear of all components of the cone crusher. If the quality of the lubricating oil of the gear is unqualified and the lubrication method is not correct, the lubrication condition of the gear will be damaged and the wear will be aggravated.

4, The Matching Degree Of The Bevel Gear Is Not Suitable

Poor gear meshing is also an important cause of the cone tooth damage of the cone crusher. If the gear meshing is not good, the tooth side clearance and the tooth tip clearance are not within the specified range, which may cause the gear to be damaged in a short time.

5, Into The Cone Crusher Into The Unbreakable Foreign Body

If the cone crusher enters an unbreakable foreign object such as an iron block, the failure of the iron-carrying device can easily cause damage to the machine components, especially the gear.

6, The Equipment Transmission Method Is Improper

The transmission mode of the cone crusher is rigid connection. The motor is rigidly connected with the gear shaft through the elastic coupling. When the cone crusher is over-iron or overloaded, it is easy to cause damage to the large and small gears.

Preventive Measures To Reduce Wear

In the face of the wear of the cone crusher cone cone, what measures should be taken to prevent it?

1. It Is Forbidden To Overload The Equipment

If too much material is put into the crushing chamber of the cone crusher, the equipment will be overloaded for a long time, which will not only increase the production volume, but also cause serious wear or even breakage of the gears or local fatigue cracks in the roots. Wait. Therefore, we must pay attention to the combination of equipment work and rest, reducing gear damage.

2. Strictly Control The Feeding

If the material put into the crushing chamber contains impurities such as iron lump, the gear will be seriously damaged. Therefore, we must strictly control the feeding in the production to reduce the damage of the gear.

3, Eliminate Additional Wear

As the gear is in operation, impact vibration and additional sliding wear are easily generated, resulting in serious damage to the gear. Therefore, we can make the center hole of the large bevel gear offset from the center line of the eccentric bushing by a distance to ensure that the large bevel gear always rotates around the fixed center line of the equipment, thereby eliminating the additional impact vibration and additional sliding wear to reduce the gear.

4, To Ensure The Normal Meshing Of The Gear

If the cone crusher gear is improperly engaged in production, the gear will be damaged faster. Therefore, we should ensure the normal meshing of the gears so that the cones of the two gears intersect at one point and the pitch circle coincides.

5, Do A Good Job Of Gear Maintenance

Do a good job in the maintenance of gears. There are two main points: First, ensure the lubrication of the gears and reduce the wear during gear operation. Second, pay attention to check whether there are any debris in the gears. If there are any debris, clean them in time to avoid Affect the meshing of the gears and reduce the damage of the cone crusher gears.
