Rack and gear lubrication system


In mechanical systems where the gears and racks is used, maintaining proper lubrication is key to ensuring smooth operation, extending component lifespan, and minimising unplanned downtime. The KHK lubrication system has been developed precisely for that purpose: to offer an effective, simple, and long-lasting solution for maintaining these systems.

 

Why is lubrication so important in rack and pinion systems?

Constant friction between the gear and rack teeth causes wear, overheating, and loss of precision if not properly controlled. Poor or irregular lubrication can lead to:

  • Increased tooth wear

  • Abnormal noise and vibrations

  • Premature system failures

  • More frequent and costly maintenance

An automatic lubrication system helps prevent all these issues, significantly reducing long-term operating costs.

 

Technical features of the KHK lubrication system


The system consists of a series of components designed to easily adapt to various industrial applications. These are the main ones:

  1. Flex pump: Accurately doses the grease for continuous system lubrication.
  2. Grease cartridge: Replaceable container with special high-adhesion, heat-resistant grease.
  3. Tube connector: Metal connection between the pump and the grease transport tube.
  4. Tube: Polyamide conduit that carries the grease from the pump to the lubrication point.
  5. Mounting shaft: Mechanical support that positions the lubricating gear in front of the rack.
  6. Lubricating gear: Made of polyurethane, it applies grease evenly over the system's teeth.

This modular design allows for quick installation without the need to redesign the existing mechanical system.
