Embodiment

[0066] see Figure 1-Figure 2 As shown, the self-lubricating bearing of this embodiment includes an outer bushing 1 and an inner lining layer 2 installed in the outer bushing, and the inner lining layer 2 includes a metal substrate 21 and a fiber resin composite layer on the metal substrate 21 22. The fiber resin composite layer 22 is made of fiber fabric impregnated with epoxy resin-based composite material and cured by hot pressing. The epoxy resin-based composite material is composed of 60% epoxy resin binder and 40% friction self-lubricating material . The epoxy resin adhesive consists of 83% epoxy resin, 7% curing agent and 10% epoxy diluent. The friction self-lubricating material is composed of 30% graphite, 20% molybdenum disulfide (MoS 2 ) and 50% polytetrafluoroethylene (PTFE) powder composition.

Abstract

The invention discloses a self-lubricating bearing based on fiber fabric modification and a manufacturing method thereof. The self-lubricating bearing comprises an outer lining and an inner lining layer installed in the outer lining, and the inner lining layer comprises a metal substrate and a fiber resin composite layer located on the metal substrate. The preparation method comprises the following steps that the fiber fabric treated by a silane coupling agent and an epoxy resin-based composite material are dipped at first to obtain a fiber fabric composite material, and the two steps of prepressing thermocuring and thermocuring are executed on the fiber fabric composite material and the metal substrate to obtain a planar dry friction self-lubricating composite material; and the planar dryfriction self-lubricating composite material is rolled into the shaft sleeve lining layer to be mounted in the outer lining, and accordingly the self-lubricating bearing can be obtained. The dry friction self-lubricating bearing is good in bearing capacity, the friction coefficient is effectively reduced, and the self-lubricating performance is remarkably improved.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to a sliding bearing and a manufacturing method, in particular to a self-lubricating bearing based on fiber fabric modification and a manufacturing method thereof. Background technique [0002] Due to the limitations of certain working conditions, sometimes sliding bearings have to work under harsh working conditions (such as high temperature, high pressure, dusty environment), and the commonly used fluid lubricated sliding bearings cannot adapt well due to the limited friction characteristics of materials. requirements of this special condition. Self-lubricating bearings can better maintain better lubrication performance under oil-free conditions by solving the limitations of relying on grease lubrication. Therefore, research on self-lubricating material bearings is the current mainstream research trend. Self-lubricating bearings with good mechanical strength and good tribological propertie...
