摘要： PURPOSE:To develop a sintered sliding material having excellent wear resistance and excellent fit to a mating member by impregnating Cu or Cu-Sn alloy to a porous sintered body consisting of powder of a high-carbon alloy steel contg. Cr, Mn, etc. CONSTITUTION:The above-mentioned metallic raw materials, pulverized powder of graphite and 0.7% lead stearate as a lubricating agent are so mixed as to obtain the compsn. consisting of, by weight %, 1-4% C, 3-20% Cr, 0.05-3.5% Mn, 0.1-10% 1 or >=2 kinds among Mo, V, Nb, and Ta and further 0.1-10% 1 or >=2 kinds of Co and Ni and the balance Fe. The mixture is press-molded. Such molding is sintered at 1,130-1,180 deg.C to form the porous sintered body and thereafter the sintered body is superposed with 100 mesh Cu powder or Cu-Sn alloy powder contg. 0.1-25% Sn and is heated in this state at 1,130 deg.C to melt the Cu or Cu-Sn alloy powder and to impregnate the same into the pores of the sintered body in a 6-25% range. A sliding member which is uni formly dispersed with hard and fine metallic carbide, is impregnated with the Cu or Cu-Sn alloy and having excellent characteristics, is thus produced.

摘要： PURPOSE:To reduce remarkably the adhesion wear of a wear resistant member made of a wear resistant material contg. hard particles dispersed in the metallic matrix by projecting part of the hard particles from the surface of the matrix. CONSTITUTION:A wear resistant member is made of a wear resistant material contg. hard particles of 1-100mum particle size dispersed in the metallic matrix. At this time, the surface of the member has hard particles projected from the surface of the matrix by 0.2-5mum. The hard particles are projected from the surface of the matrix by lapping the surface of the member with abrasive grains which are harder than the matrix metal and softer than the hard particles or by chemically leaching out the matrix metal.

摘要： PURPOSE:To firmly fix a work engaged with a rotary shaft to a rotary shaft by projecting the end face chamfered of the work rather than the end face of the rotary shaft and closely engaging a resilient member in the recess defined by both the internal peripheral face of the work on the projecting part and the end face of the rotary shaft. CONSTITUTION:A cylindrical work 1 to be cut is engaged at one end face thereof with a rotary shaft 10 and engaged at the other end face 1a with the contact face 3a of the rotary shaft 10. By turning the work 1 with the rotary shaft 10, the external peripheral face of the work 1 or the ridge part defined by both said face and the other end face 1b is chamfered by a cutting tool 4. At this time, said end face 1b of the work 1 projects rather than the end face 10a of the rotary shaft. A resilient member 16 is engaged in the recess part 15 defined by both the internal peripheral face of the work 1 at the projecting part and the end face 10a of the rotary shaft. Said resilient member 16 is closely brought into contact with both the internal peripheral face of the work 1 and the end face 10a of the rotary shaft 10 to generate friction force, by which the work 1 is tightly fixed to the rotary shaft 10. As a result, the idle run of the work against turning of the rotary shaft 10 may be prevented.

摘要： PURPOSE:To increase the surface sticking hardness between a Cu-applied layer and a Fe-applied layer by preliminarily applying powder adhering liquid on the area which faces to the friction face of a bearing, filling the Cu powder and the Fe powder, compressing and shaping them. CONSTITUTION:Powder adhering liquid R which incurs no adverse effect in the sintering is applied on the external face of the end part of a core rod 12 projecting from a lower punch 13. Next, Cu powder is sprayed against the applied adhering liquid R to form an extremely thin Cu coat on the external face of the end part of the core rod 12. Then, the core rod 12 and lower rods 13 are pressed down integrally and each of the spaces defined by the external face of the end part of the core rod 12, the upper face of the lower punch 13 and the internal face of a die 11 is filled with Fe powder. The Cu coat can then be made thin to the desired degree and the surface sticking forces of both the Cu coat and the Fe coat can be increased.

摘要： PURPOSE:To form a tip to be brought into smooth contact with a cam and reduce wearing, by using a sintered metal material for the tip mounted to a contact part between a rocker arm and the cam. CONSTITUTION:A rocker arm 1 mounts a tip 3 to a part where the rocker arm is brought into contact with a cam 2. The tip 3 is prepared by molding and sintering to density ratio of 95% or more. The tip 3 under this condition of simple substance forms a contact surface (called a butt surface) with the cam 2 to be machined to a dimension and surface roughness of the rocker arm 1 when it is completed, providing a plating layer 4 of 5-50mu by electroless nickel plating. This nickel may be considered to be substantially composed of 90-92% nickel and 8-10% phosphor. In this way, a metallic coating layer, sufficiently forming by its initial wearing a familiarized surface with the cam, brings the tip into smooth contact with the cam.

摘要： PURPOSE:To aim at the promotion of lightweightness and improvements in a sliding characteristic and abrasion resistance, by forming a shaft part and an eccentric rotor part both with aluminum or its alloy, while forming an anodic oxide film, made up of anodic treatment, on the rotor eccentric part surface. CONSTITUTION:Oxide film layers A of a film made up of anodic treatment, a film made up of taprum process, etc., are formed on the surface of an eccentric rotor part 5. It is a matter of course that the oxided film layers A may be formed on not only the eccentric rotor part but also on a shaft part 4a. With this constitution, a sliding characteristic and abrasion resistance with a piston is well improvable. In addition, since the shaft part 4a and the eccentric rotor part 5 use aluminum or its alloy as material, both parts 4a and 5 are made to be lightweight, whereby high speed output is securable and, what is more, vibro- absorbability and sound absorbability as a property inherent in aluminum are securable so that vibration and noise both are reducible.
摘要翻译：目的：通过在铝或其合金中形成轴部分和偏心转子部分，同时形成由阳极处理组成的阳极氧化膜，旨在促进轻量化和滑动特性和耐磨性的提高，转子偏心部分表面。构成：在偏心转子部5的表面上形成由阳极处理构成的膜的氧化膜层A，由锥形法等构成的膜。当然，氧化膜层A 不仅可以形成在偏心转子部分上，而且还可以形成在轴部分4a上。利用这种构造，具有活塞的滑动特性和耐磨性是非常好的。此外，由于轴部4a和偏心转子部5使用铝或其合金作为材料，所以使得部件4a和5都重量轻，由此高速输出是可固定的，更重要的是振动吸收性和声音作为铝固有的性质的吸收性是可固化的，使得振动和噪声都可以减少。
