  • The Research of the Slewing Bearing Force

    The slewing bearing of the full-revolving super large lifting equipment bears all loads above the rotating platform. Due to the effect of bending moment, the load conditions of the slewing bearing structure is complex and large, which leads to the non-uniform of stress and uneven deformation and final seriously affects the work performance of lifting equipment.

  • Limit Speed And Friction Coefficient Of Bearing -

    2020-4-28 · Limit Speed And Friction Coefficient Of Bearing Apr 28, 2020. The speed of the bearing is mainly limited by the temperature rise caused by friction and heat in the bearing. When the speed exceeds a certain limit, the bearing cannot continue to rotate due to burns.

  • (PDF) Screw behavior in large diameter slewing

    A slewing bearing with only 30% left of its calculated service life can be well worth remanufacturing. SKF's standardized remanufacturing processes can extend significantly the service life of critical equipment. All of these combine to improve rotating equipment performance and reduce total cost of ownership.

  • Calculation of the friction torque of the Slewing

    2019-2-18 · The maximum lifting torque of a large-tonnage slewing crane can reach more than 100,000 tons. In this case, the horizontal and vertical forces of the slewing bearing are relatively large, and the load can reach more than 3000t. For the upper roller, there is great difficulty in the design of the single roller.

  • Slewing Rings (Turntable Bearings) Technical

    The friction in a spherical plain bearing or rod end depends primarily on the sliding contact surface combination, the load and the sliding velocity. Because there are so many influencing factors that are not mutually independent, it is not possible to quote exact values for the coefficient of friction.
