Proposed is a novel coupling mechanism capable of applying a preload to a ball portion and a socket portion which constitute a coupling mechanism of a titling pad bearing, without using a spring element.

There is provided an ultraviolet curable resin composition for a self-lubricating liner, including: a (meth)acrylate compound having an isocyanuric acid ring; at least one of (meth)acrylate having a phosphoric acid ester group and (meth)acrylate having a silane group: a polythiol compound; and a polytetrafluoroethylene resin as a solid lubricant.

A metal matrix self-lubricating composite and a manufacturing method therefor. The metal matrix self-lubricating composite comprises a metal matrix and a mixture layer compounded on a surface of the metal matrix, the mixed layer comprising a copper alloy and a self-lubricating material. The method for manufacturing the metal matrix self-lubricating composite comprises the following steps: a) sintering copper alloy powder on a surface of a metal matrix to form a copper alloy layer on the surface of the metal matrix; b) blade-coating or dip-coating a lubricating material on a surface of the copper alloy layer, and performing vacuumization to obtain a metal plate, and drying the metal plate; c) repeating step b) for multiple times; and d) sintering the metal plate obtained in step c) to obtain the metal matrix self-lubricating composite. In the present invention, a vacuumization mode is used and vacuumization operations are repeated, so that a dense mixture layer on which a self-lubricating material is dispersed on a copper alloy is formed, and the metal matrix self-lubricating composite has good lubricity and abrasion resistance.

A method for lubricating a generator bearing assembly is presented. The generator bearing assembly has a bearing and a bearing seat that supports the bearing. A coating of a lubricating material is applied at an interfacing surface between the bearing and the bearing seat. A curing process is performed to the coating by heating the coating up to a predefined curing temperature.
