Sliding bearing member

Abstract

A sliding bearing member comprising: A. polyacetal resin base B. organic fibers C. hydrocarbon lubricating oil D. metallic soap E. solid inorganic lubricant.

I claim: 
     
       1. A sliding member made of a material consisting of 0.1-15 percent by weight of an organic fiber material having a length less than about 3mm. and a diameter of about 15-50 microns and having oil affinity, 1-15 percent by weight of a hydrocarbon lubricating oil, and the balance of polyacetal resin. 
     
     
       2. A sliding member made of a material consisting of 0.1-15 percent by weight of an organic fiber material having a length less than about 3mm. and a diameter of about 15-50 microns and having oil affinity, 1-15 percent by weight of a hydrocarbon lubricating oil, 0.1-10 percent by weight of a metallic soap, and the balance of polyacetal resin. 
     
     
       3. A sliding member made of a material consisting of 0.1-15 percent by weight of an organic fiber material having a length less than about 3mm. and a diameter of about 15-50 microns and having oil affinity, 1-15 percent by weight of a hydrocarbon lubricating oil, 0.1-10 percent by weight of a metallic soap, 0.1-10 percent by weight of a solid inorganic lubricant, and the balance of polyacetal resin. 
     
     
       4. A method of manufacturing a sliding member which comprises mixing and stirring in a container from 0.1-15 percent by weight of an organic fiber having a length less than about 3mm. and a diameter of about 15-50 microns and having oil affinity, from 1-15 percent by weight of a hydrocarbon lubricating oil, and polyacetal resin as the balance, heating to a temperature above the melting point of the resin to melt the composition, solidifying the composition, crushing the solidified composition, molding the crushed composition into a sliding member. 
     
     
       5. A method as set forth in claim 4, wherein the composition additionally contains from 0.1-10 percent by weight of a metallic soap in the mixing and stirring step. 
     
     
       6. A method of claim 5, wherein the composition additionally contains from 0.1-10 percent by weight of a solid inorganic lubricant in the mixing and stirring step. .Iadd. 7. A sliding member made of a material consisting of 0.1-15% by weight of an organic fiber material having a length less than about 3mm. and a diameter of about 15 - 50μ and having oil affinity, 1 - 15% by weight of a hydrocarbon lubricating oil, 0.1 - 10% by weight of a solid inorganic lubricant, and the balance of polyacetal resin. .Iaddend..Iadd. 8. A method of making a sliding member which comprises mixing and stirring in a container from 0.1-15% by weight of an organic fiber material having a length less than about 3mm. and a diameter of about 15 - 50μ and having oil affinity, 1-15% by weight of a hydrocarbon lubricating oil, 0.1-10% by weight of a solid inorganic lubricant, and balance polyacetal resin,   heating to a temperature above the melting point of said resin to melt the composition,   solidifying the composition,   crushing the solidified composition, and   molding the crushed composition into a sliding member.
