Services

The refurbishment and overhaul of multi-brand planetary gearboxes are essential processes used across key industries such as sugarcane bioenergy, mining, steelmaking, and cement production. Mult Engrenagens stands out in this field by delivering high-quality services, including the refurbishment and repowering of rotary assemblies, along with innovative solutions to optimize lubrication and cooling systems.

Refurbishment and Repowering of the Rotary Assembly

During the refurbishment of planetary gearboxes, Mult Engrenagens conducts a detailed analysis and comprehensive repowering of the rotary assembly, focusing on critical components such as:

• Sun Shaft: Responsible for transmitting motion and torque, the sun shaft often suffers wear and cracks, which are repaired as part of the refurbishment process.
• Planet Gears: Fundamental for speed reduction, these gears may experience wear or failure, requiring repair or replacement to restore gearbox performance.
• Ring Gear: Playing a vital role in torque distribution and gearbox operation, maintaining the integrity of the ring gear is critical for proper system functionality.
• Planet Carrier: Provides structural support for the planetary gears, ensuring the smooth operation of the assembly.

High-Flow Breather Installation

Another key aspect of planetary gearbox refurbishment is the installation of a high-flow breather system designed to:

• Eliminate Internal Pressure: The high-flow breather helps remove internal pressure generated by oil heating during operation, preventing air bubble formation and oil degradation.
• Prevent Oil Contamination: By regulating internal pressure, the breather protects the oil from contamination by water or external particles, maintaining system efficiency and reducing component wear.

Lubrication Modification

Mult Engrenagens also introduces significant improvements in the lubrication of input bearings, implementing a critical modification:

• Switch from Grease to Oil: Replacing grease with an oil-based lubrication system for input bearings offers several benefits:
• Extended Bearing Life: Oil provides superior lubrication and cooling, reducing friction and wear, and significantly extending bearing life.
• Reduced Monitoring and Replacement Needs: Oil lubrication eliminates the frequent monitoring and replenishment required by grease systems, resulting in fewer interventions and reduced equipment downtime.
