Abstract

The invention provides an integrated metal-based macromolecular composite self-lubrication bearing. The integrated metal-based macromolecular composite self-lubrication bearing comprises an externally-circular metal shaft sleeve, a steel plate layer and a plastic layer, wherein an inner diameter ring groove is formed in the inner surface of the externally-circular metal shaft sleeve; the steel plate layer is fixed at the interior of the externally-circular metal shaft sleeve; the outer surface of the metal plate layer is in contact with the inner surface of the externally-circular metal shaft sleeve; a plurality of through holes are formed in the steel plate layer; the plastic layer is fixed on the steel plate layer; the plastic layer comprises an abrasion-proof layer and a fixing layer; the abrasion-proof layer is in contact with the inner surface of the steel plate layer; and the fixing layer is filled into the through holes of the steel plate layer and the inner diameter ring groove of the externally-circular metal shaft sleeve. The integrated metal-based macromolecular composite self-lubrication bearing takes the externally-circular metal shaft sleeve as a base material and is low in cost and easily available in materials; more importantly, the integrated metal-based macromolecular composite self-lubrication bearing is high in abrasion resistance; the experiment results show that the abrasion loss is smaller than 0.1mm after testing for 50 hours under the condition that the lubrication oil is coated at one time at the speed of 0.7m/s under the pressure of 1.2MPa.

Description

technical field [0001] The invention relates to the technical field of bearings, and more specifically relates to an integral metal-based polymer composite self-lubricating bearing and a manufacturing method thereof. Background technique [0002] Injection molding machine is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products with plastic molding molds. It is widely used in national defense, electromechanical, automobile, transportation, building materials, packaging, agriculture, culture, education and health and people's daily all areas of life. [0003] The mold clamping part in the injection molding machine is one of the important parts. Its function is to realize the opening and closing movement through the reciprocating motion of the Green column, so that the mold is closed to generate elastic deformation of the system to achieve the clamping force, and the mold is locked tightly, which plays a key role...
