Slewing bearing and applications thereof

A slewing bearing for vertical structural support, comprising a first bearing ring, a second bearing ring and at least one row of rolling elements arranged between the first and second bearing rings, said first or second bearing ring being provided with a gear for receiving the drive of an input torque, wherein the gear is provided axially thereunder with a lubricant collecting member for collecting and storing a lubricant, wherein the lubricant collecting member and the gear are integrally formed and fixedly arranged on one of the group of the first bearing ring and the second bearing ring in the form of a gear plate.

A rotary support device for supporting in a vertical structure, comprising:

• a first member that supports substantially in a vertical direction, a second member that is substantially supported by the first member in the vertical direction, and a slewing bearing for the vertical structural support, comprising a first bearing ring, a second bearing ring and at least one row of rolling elements arranged between the first and second bearing rings, the second bearing ring being integrally formed with a gear for receiving the drive of an input torque, wherein the gear is provided axially thereunder with a lubricant collecting member for collecting and storing a lubricant, wherein the first member is fixedly connected to the first bearing ring of the bearing, and the second member is fixedly connected to the second bearing ring of the bearing, the gear having a plurality of gear teeth which are aligned with an upper surface of the second bearing ring, wherein when the gear arranged on the second bearing ring is driven by the input torque, it will drive the second member to rotate relative to the first member.
