The invention discloses a self-overflow lubrication type powder metallurgy copper sleeve, belonging to the field of metallurgical copper sleeves. A self-overflow lubrication type powder metallurgy copper sleeve is provided. The heat generated by the rotation of the bearing is transferred to the positioning ring block through the rotation of the placement ball The expansion of the expansion block causes the deformation of the elastic film on the one hand, and the deformation of the elastic film squeezes the oil storage block, which is convenient to release the lubricating oil inside the oil storage block through the oil guide pipe on the copper sleeve. The inner surface of the body can effectively lubricate through the form of self-overflow. The end of the through mandrel is fixedly connected with an overflow hole. The setting of the overflow hole facilitates the transfer of a part of the graphite particles to the friction surface of the shaft and the bearing. The heat dissipation panels are arranged at equal intervals, so that the residual heat remaining on the thermal conductive fibers can be easily treated, so that the metallurgical copper sleeve can be effectively protected.
Description
technical field [0001] The invention relates to the field of metallurgical copper sleeves, more particularly, to a self-overflow lubrication type powder metallurgy copper sleeve. Background technique [0002] There are many kinds of copper sleeves, including machine copper rollers, copper bearings, etc. Oil lubricated bearings are used in various large and heavy machinery and are an important component of machinery. The product has the function of traditional tin bronze bearing. It is made of electrolytic copper as raw material with various trace metal elements, sintered at high temperature, and processed by air pressure centrifugal casting. High hardness, excellent wear resistance, not easy to cause seizure, good casting performance and cutting performance, and good corrosion resistance in the atmosphere and fresh water. [0003] Powder metallurgy of bracket copper sleeve is to mix powdered iron or copper and other basic materials with graphite, and then press and sinter ...
