Problems solved by technology

[0002] In the known technology, bearing lubrication mainly includes grease lubrication and oil lubrication. Grease lubrication needs to be filled with grease regularly, and oil lubrication needs to be pumped by setting an oil throwing ring or soaking the bearing in an oil pool to force lubrication through an oil wedge. The oil will also splash strongly, which not only wastes lubricating oil but also pollutes the environment
Under these two lubrication methods, the bearing lubrication effect is not ideal

Embodiment

[0013] Figure 1 ~ Figure 3 It is an embodiment disclosed by the present invention. Four identical semicircular grooves 5 are symmetrically processed on the axle sleeve 2 (two adjacent semicircular grooves 5 are separated by 90°), and each semicircular groove 5 is opened at the center of the axle sleeve 2 . The self-lubricating block 3 is sintered by powdery molybdenum disulfide, and its cross-section is made into a triangular structure. The arc surface is the same as the arc surface of the fixed shaft 1. A circular through hole 6 is opened on one side of the self-lubricating block 3. The size of the circular through hole 6 depends on the volume of the self-lubricating block 3. The height of the circular through hole 6 is embedded The density mass 4 and the high-density mass 4 are made of stainless steel, and the high-density mass 4 and the self-lubricating block 3 are interference fits (see image 3 ). The self-lubricating block 3 comprising the high-density mass block 4 i...

Abstract

The invention discloses a self-lubricating bearing. Four semi-circle grooves (5) of a same structure are symmetrically processed in the inner surface of a shaft sleeve (2) of the self-lubricating bearing; a cross section of each of self-lubricating blocks (3) is of a triangular structure; a high-density mass block (4) is embedded in a circular hole (6) formed in one side of each of the self-lubricating blocks (3); the self-lubricating block (3) embedded with the mass block (4) on the right side is placed in the two symmetrical semi-circle grooves (5), and the other self-lubricating block (3) embedded with the mass block (4) on the left side is placed in the other two symmetrical semi-circle grooves (5); in a rotation process of the shaft sleeve (2), centrifugal force is formed on one sideof each of the self-lubricating blocks (3) on which the corresponding mass block (4) is embedded, so that the purpose of bearing lubrication is achieved when the self-lubricating blocks (3) are in contact friction with a fixed shaft (1) under the effect of the centrifugal force. The self-lubricating bearing has the advantages that the self-compensation, uniformity and continuity of lubrication areimproved, and the carrying capacity, the rotation efficiency and the service life of the bearing are also improved.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a self-lubricating bearing. Background technique [0002] In the known technology, bearing lubrication mainly includes grease lubrication and oil lubrication. Grease lubrication needs to be filled with grease regularly, and oil lubrication needs to be pumped by setting an oil throwing ring or soaking the bearing in an oil pool to force lubrication through an oil wedge. The oil will also splash strongly, which not only wastes lubricating oil but also pollutes the environment. Under these two lubrication methods, the bearing lubrication effect is not ideal. In order to solve the shortcomings of the prior art, the invention provides a stable and reliable self-lubricating bearing. The lubrication performance of the bearing plays a decisive role in the bearing capacity and service life; among them, the self-compensation of the lubricant is crucial to the bearing. The present inven...
