Abstract

A slewing bearing comprises an inner ring, an outer ring and multiple rolling bodies located between the inner ring and the outer ring; one of the inner ring and the outer ring is a rotary ring, and the other is a non-rotary ring; a supporting part is installed on the non-rotary ring and at one end in the axial direction of the slewing bearing and is back on to the surfaces of the multiple rolling bodies, the inner ring and the outer ring in the axial direction to define a containing chamber; at least two brake mechanisms are arranged in the containing chamber; at least one of the brake mechanisms is used for locking and unlocking when the rotary ring rotates clockwise, and at least the other brake mechanism is used for locking and unlocking when the rotary ring rotates anticlockwise. The brake mechanisms are integrated in the slewing bearing through the supporting part. The brake mechanisms do not limit the application occasions of the slewing bearing, and the installation process is simple and convenient.

Description

technical field [0001] The invention relates to a bearing, in particular to a slewing bearing. Background technique [0002] The slewing bearings of the prior art cannot be mounted to an external slewing structure in the axial direction if the installation space on one of the mounting sides is limited. In order to solve the above problems, the applicant once proposed a solution to solve the above problems, which is: [0003] refer to figure 1 , the slewing bearing includes a coaxial inner ring 1, an outer ring 2 surrounding the inner ring 1, an outer ring 3 surrounding the inner ring 1 and connected to the inner ring 1, the outer ring 3 is axially opposite to the outer ring 2, and the inner ring 1 There are two sets of rolling elements 4 separated from each other between the outer ring 2 and the outer ring 2 . [0004] On the end surface of the outer ring 3 opposite to the outer ring 2 , a plurality of first threaded holes 31 are arranged at intervals along the circumfere...
