Self-lubricating bearing

Abstract

The invention discloses a self-lubricating bearing. The main content is: the left inner ring is fixedly installed together with the right inner ring through bolts, and the outer ring is installed horizontally in the groove between the right inner ring and the left inner ring. Radial filler, axial filler is installed between the right end surface of the boss of the left inner ring and the bottom surface of the groove at the left end of the outer ring, and axial filler is installed between the left end surface of the boss of the right inner ring and the bottom surface of the groove at the right end of the outer ring. The filler, the right inner ring and the left inner ring are fixedly installed on the support through the dust-proof ring, and the dust-proof ring is stuck in the groove on the support, and the joint surface between the right inner ring and the left inner ring and the support A rubber gasket is installed, and the outer ring is fixedly installed on the right inner ring and the left inner ring through the end face collar, and an "O" type sealing ring is installed at the horizontal contact between the outer ring and the left inner ring, and the outer ring and the right inner ring An "O" type seal ring is installed at the contact point in the horizontal direction, the left end face clamp ring is stuck in the groove of the left inner ring, and the right end face clamp ring is stuck in the groove of the right inner ring.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a self-lubricating bearing. Background technique [0002] In large machinery, especially construction machinery, the application of extra large bearings is becoming more and more extensive. Extra large bearings are generally in the form of rolling bearings and require good sealing and lubrication. The extra-large bearings used today, because they are immersed in seawater and withstand seawater pressure, the bearing support is fixed on a cylindrical shell with a diameter of 7.6m. With the radial deformation, the slewing bearing in the form of traditional rolling bearing, the high contact stress between the rolling element and the track will cause rapid wear and corrosion under the action of seawater, and the bearing life will be greatly shortened. Contents of the invention [0003] According to the above disadvantages, the present invention provides a self-lubricating bearing...
