A manufacturing method of a water lubricated bearing taking hard rubber as a liner belongs to the field of a manufacturing method of a bearing. The problem that the existing manufacturing method of the
rubber bearing is inapplicable for the water lubricated bearing taking the high-
hardness rubber as the liner is solved. The method comprises the following steps of: mixing and milling the hard rubber by a double-
roller mill, winding the mixed and milled hard rubber on a
central spindle, arranging the mixed and milled hard rubber on a mold base, covering an upper cover of the mold on the mixed and milled hard rubber, arranging the mold on a vulcanizing
machine, vulcanizing for 20-30min under the condition of 120 DEG C to 180 DEG C, opening the mold, de-molding, obtaining the water lubricated bearing lining blank product, performing
machine finishing to the water lubricated bearing lining blank product, then arranging the product in a bearing sleeve, and obtaining the water lubricated bearing taking the hard rubber as the liner. Aiming at the defect that the hard rubber is hard to flow, a novel sleeve mold and the vulcanizing technique are used for preparing the water lubricated bearing; and the preparation method is simple, and high in efficiency, and is beneficial for
mass production.
