The demand for ever higher transferable power and torques with simultaneous reduction in size and weight is often difficult to achieve in practice. This makes it all the more important to apply effective lubrication, which helps to optimise spindles and open gears.

  • 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 operation, lubricants with EP additives and MoS2 are generally used which can withstand high stress loads (mixed friction, load, corrosion and aggressive influences).

  • Challenges

    perma lubrication systems with suitable accessories for applying the lubricant to the gear surface guarantee effective relubrication. Permanent renewal of the lubricant film with subsequent lubricant distribution 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 often come into contact with dirt or dust, such as cement or coal dust, which accelerates wear and corrosion.
