Spindles & open gears

The demand for ever higher transferable power and torques with simultaneous reduction in size and weight can often only be implemented with difficulty in practice. This makes it all the more important to implement effective lubrication, contributing to optimisation of a rack and pinion drive.

  • Lubrication points

    Relubrication is especially important for enhancing the service life and availability of gear ring drives. Right at the beginning of the bedding-in phase, care must be taken that the tooth flank surfaces are smooth.

    During running operations, graphite-containing adhesive lubricants are generally employed, which withstand the high loads (mixed friction, loads, corrosion, aggressive impacts).

  • Challenges

    In order to ensure relubrication occurs, a lubrication system with matching accessories for transferring the lubricant to the gear surface can be used. Permanent renewal of the lubricant film with subsequent lubricant transfer to additional gear wheel pairs helps to reduce wear in the long-term and increases gear wheel service life.

    Large gear ring drives are used where heavy loads need to be moved, e.g. in rotary kilns and ball mills. Because of their occasionally considerable dimensions, the gear teeth on gear rings often cannot be effectively protected against environmental impacts.

    Open gear ring and spindle drives are often used in contact with dirt, abrasive cement and coal dust, which accelerates wear and corrosion.

    • Dust, liquids and contamination
