Self lubricating bearings for vertical suspended semi submersible vertical turbine pumps

A self-lubricating bearing is used for a vertical suspended semi submersible vertical turbine pump, which includes an outer rubber sleeve and a self-lubricating inner liner. The outer rubber sleeve forms the outer wall of the bearing, and the lubricating inner liner is coaxially embedded in the outer rubber sleeve to form the self-lubricating inner wall of the bearing. The bearings provided in this scheme are composed of outer rubber sleeves and lubricating inner bushings with different structures and materials inside and outside. The lubricating inner bushings achieve good avoidance and shock absorption of the bearings, while also being able to adapt to water lubrication. They have high strength, are easy to inject, are wear-resistant, and have a low friction coefficient; When cooperating with the transmission shaft, it can allow a certain amount of dry friction for a certain period of time without rapid heating and deformation, effectively solving the problems existing in the existing technology.

Technical requirements: 1. Self lubricating bearings for vertical suspended semi submersible vertical turbine pumps, characterized in that the self-lubricating shaft includes an outer rubber sleeve and a self-lubricating lubricating inner liner, the outer rubber sleeve constitutes the outer wall of the bearing, the lubricating inner liner is coaxially embedded in the outer rubber sleeve to constitute the self-lubricating inner wall of the bearing, and the lubricating inner liner is composed of arc-shaped side walls of the same thickness and arc-shaped side walls connected in sequence. The outer convex top of the arc-shaped side wall is in contact with the inner wall of the outer rubber sleeve to form a hollow structure between the inner wall of the lubricating inner liner and the inner wall of the outer rubber sleeve, so that the lubricating inner liner has good deformation space; By sequentially connecting the arc-shaped side walls and coordinating them with each other, a good restoring elasticity is formed, making the self-lubricating bearing have excellent avoidance and shock absorption properties. The inner wall formed by the lubricating liner always adheres to the surface of the inserted transmission shaft, providing good support for the transmission shaft.
