  • Analysis of slewing ring

    1、 Analysis of raw materials of slewing ringSlewing ring is mainly composed of inner ring and outer ring. The materials of conventional inner and outer rings are 50Mn and 42CrMo. 50Mn is carbon structural steel and 42CrMo is alloy structural steel. 50Mn has high strength, elasticity and hardness. 42

  • Slewing drive slew drives

    Slewing drive is a kind of all-round slewing decelerating transmission mechanism integrated with driving power source. It uses slewing ring as driving follower and mechanism attachment. By attaching the driving part, driving source and cover on one of the inner and outer rings of slewing ring, the o

  • What should we pay attention to when the slewing ring is overloaded?

    When the slewing ring is used under overload, it may be stuck and unable to rotate. In this time, the vehicle body can be tilted by reducing the amplitude, adjusting the outrigger or moving the chassis position, so as to help realize the slewing movement of heavy objects and complete the predetermin

  • Reasons why elastic washer can not be used for slewing ring

    The slewing ring cannot prevent wear. Some customers want to reduce costs, they want to install elastic washers on the slewing ring to reduce this kind of wear. In fact, it is a very serious misconception! Although the wear of the slewing ring can not be prevented, people can repair the wear very we
Analysis of Accuracy Class of Slewing Bearings
