Causes and Troubleshooting Tips for Lubrication Component Failures in Crawler Mobile Stone Crushers

Crawler mobile stone crushers are known for their strong crushing capability, high crushing ratio, stable quality, low production cost, and ease of maintenance. They are extensively utilized for primary, secondary, and tertiary crushing operations for medium-hardness materials. Lubrication components help reduce downtime due to overheating, lower maintenance expenses, reduce part replacements, and prolong equipment lifespan. Bel

I. Symptoms and Causes of Lubrication Component Failures

1. Sluggish Operation of Crawler Mobile Stone Crusher
The equipment operates sluggishly with uneven speed and high power consumption, causing vibrations, noise, and occasional overheating of the motor. Increasing motor power at this point will further overheat the machinery, severely damaging transmission components such as bearings, belts, and gears.

Causes:

• Improper installation or design defects in friction components (e.g., sliding bearings with insufficient clearance), increasing friction and causing unstable movement.
• Incorrect material combinations or inappropriate lubricant choices, leading to unstable motion and increased risk of adhesive wear.
• Foreign matter contamination.

2. Vibration and Noise in Crawler Mobile Stone Crushers
During operation, abnormal vibrations and noise degrade performance and may result in environmental non-compliance.

3. Overheating of Equipment
Causes:

• Excessive frictional resistance leading to intense heat generation.
• Lubricant with overly high viscosity, excessive lubrication oil volume, poor fluidity, or ineffective heat dissipation.
• Poor heat dissipation conditions, high ambient temperature, inadequate ventilation preventing timely heat dispersion.

4. Crusher Unable to Operate
Causes include severe contamination by sand and soil causing jamming, overheating, significant deterioration of friction components, or severe adhesive wear.

II. Practical Lubrication Techniques for Crawler Mobile Stone Crushers

(1) Rolling Bearings
Proper lubrication of rolling bearings includes choosing the correct bearing type, correct installation, accurately adjusting axial clearance, ensuring shaft machining accuracy, selecting lubricants with suitable viscosity, and maintaining system and lubricant cleanliness.

(2) Air Compressors
An air compressor integrates various components, and lubrication failures typically arise from poor assembly accuracy, inadequate operational and maintenance skills, contamination or deterioration of lubricant, or insufficient lubricant supply.

(3) Sealing Devices
For sealing devices to operate reliably over long periods, maintaining a lubricating and sealing oil film (around 1μm thick) on the friction contact surfaces is essential. Even minor surface damage or deformation can cause oil leakage. Thus, careful handling and inspection are necessary. Synthetic rubber seals such as O-rings and lip seals must be regularly checked for oil type compatibility, pressure, and temperature conditions to prevent damage and subsequent mechanical failure.

(4) Oil Pumps
Oil pumps are trending towards higher pressure, higher speed, and larger capacities, making lubrication critical. The hydraulic working oil should possess appropriate viscosity, excellent anti-wear properties, and resistance to adhesive wear. Effective contamination control in the working oil is also crucial.

The primary goal of lubrication management for crawler mobile stone crushers is to prevent lubrication-related failures, reduce downtime losses, and improve economic efficiency.
