Abstract

The invention discloses a multi-layer laminated elastic-plastic alloy automatic fluid lubricating bearing and a manufacturing method thereof. The bearing comprises a bearing body, an elastic damping layer and a bearing bush layer, wherein the elastic damping layer and the bearing bush layer are sequentially arranged on the inner surface of the bearing body. The manufacturing method of the bearing comprises the following steps: (1) processing an axial limiting ring groove and a radial limiting dovetail groove in the inner surface of the bearing body; (2) sanding the inner surface of the bearing block and removing greasy dirt; (3) coating the inner surface of the bearing body with a prime coat adhesive, drying, and coating a topcoat adhesive, drying at a room temperature, and rebaking to form an adhesive layer; (4) coating the adhesive layer with the elastic damping layer, when the adhesive is nearly completely solidified, i.e., the damping layer is in a wire-drawing state, coating the bearing bush layer, and solidifying; and (5) annealing. A German NDI engineering elastomer material is introduced between a bearing bush and the bearing body as the elastic damping layer, so that the fluid lubricating bearing has damping cushioning property and axis adaptability; and the problems of dry start-up and eccentric abrasion of upper and middle guide bearings of a water pump are effectively solved.

Description

technical field [0001] The invention relates to a multi-layer laminated elastic-plastic alloy self-fluid lubricating bearing and a manufacturing method thereof. Background technique [0002] A low-noise split water-lubricated rubber bearing similar to the existing centrifugal casting process is formed by directly vulcanizing rubber on a metal half shaft sleeve. The existing centrifugal casting process casts a layer of 2-15mm elastic-plastic alloy material on the inner wall of the metal bearing seat (backing). This layer of material is formed over the bearing backing and bonded by an adhesive. The inner wall of the metal backing can have a ring groove or a keyway to prevent relative movement. Many rubber bearings use this structure. [0003] The mating surface of the segmented shaft connection jumps greatly, forming a groove cutting the inner surface of the bearing, or a certain axis is bent after the segmented shaft is connected, causing the shaft (sleeve) and bearing of ...
