Seamless inner surface treatment self-lubricating sliding bearing

Abstract

The invention discloses a self-lubricating sliding bearing with seamless inner surface treatment, belonging to the technical field of bearings, comprising a support seat; balls are sleeved inside the fixed frame; the outer wall of the ball and the inner wall of the outer ring body are attached to each other; There is an oil storage chamber; the side wall of the support seat is provided with a protective tube; the inside of the protective tube is penetrated with cotton thread; the inside of the protective tube is respectively provided with a first limit sleeve and a second limit sleeve; the outer wall of the second limit sleeve There is an adjustment knob in the screw connection; the cotton thread runs through the inside of the first limit sleeve and the second limit sleeve; the top of the cotton thread extends into the inside of the fixing plate; the outer wall of the fixing plate is provided with a sponge pad; the side wall of the support seat and the storage A filling cap is provided at the opposite position of the oil chamber. The self-lubricating sliding bearing of the present invention can stably and evenly apply lubricating oil to each ball to realize self-lubricating of the bearing.

Description

technical field [0001] The invention relates to a sliding bearing, in particular to a self-lubricating sliding bearing with seamless inner surface treatment, belonging to the technical field of bearings. Background technique [0002] Sliding bearings are bearings that work under sliding friction; sliding bearings work smoothly, reliably, and without noise; under liquid lubrication conditions, the sliding surface is separated by lubricating oil without direct contact, and can also greatly reduce friction loss and surface wear, oil film It also has a certain vibration-absorbing ability; but the starting friction resistance is relatively large. However, the current sliding bearings cannot achieve self-lubrication well, and manual operation is required when adding lubricating oil, and most of the lubricating oil can only be added to a certain fixed area, and cannot lubricate each ball. Contents of the invention [0003] The main purpose of the present invention is to provide ...
