Abstract
The invention discloses a fiber wound reinforced self-lubricating composite bearing and a manufacturing method thereof. The bearing comprises an inner winding layer and an outer winding layer, the inner winding layer is formed by the way that polytetrafluoroethylenefiber and other high wearable fiber are mixed and dipped by resin glue solution and then winding is carried out, wherein other wearable fiber is one or two of aramid fiber, polyester fiber, ultrahigh molecular weightpolyethylene fiber and carbon fiber; and the outer winding layer is wound on the inner winding layer by virtue of alkali-free long glass fiber dipped in resin glue solution, thus being as the backing of the bearing. The fiber wound reinforced self-lubricating composite bearing of the invention has the characteristics of high bearing capacity, good wear resistance and low cost, can be used for preparing self-lubricating radial sliding bearing and is widely applied to lubrication free work places in rotating, swinging, reciprocating and sliding motion modes.
Description
technical field [0001] The invention relates to a self-lubricating composite sliding bearing and a manufacturing method thereof, in particular to a winding fiber reinforced self-lubricating composite sliding bearing and a manufacturing method thereof. technical background [0002] In recent years, with the massive consumption of non-ferrous metals and the increase in the cost of non-ferrous metals, the technology of replacing metal materials with organic polymer materials as structural and functional components has achieved rapid development. Fiber-reinforced epoxy resin composites are a type of high-strength reinforced materials. Because such materials have the characteristics of high hardness and high strength of thermosetting resins, the reinforced materials have excellent mechanical properties. Fiber-reinforced resin-based self-lubricating composite bearings have been one of the key directions in the research and development of new bearings because of their advantages su...
