摘要： PURPOSE:To suppress abrasion of a counterpart sliding surface by preventing surface roughness while preventing both fatigue damages of a surface starting point and an inner part starting point by applying remaining stress in a wide range under the surface of a sliding surface. CONSTITUTION:Shot peening treatment is carried out on at least either one of sliding surface 10a, 13a in a cam 10 and a roller 13, and then, barrel finishing is carried out. The value of surface roughness of the sliding surface 10a, 13a which is generated by barrel finishing after shot peeling treatment may be set to 1mumRz and less. Not only sufficient remaining stress is applied on a deep part under surface in the sliding surfaces 10a, 13a, but also it is applied on a most surface part. Since surface roughness at the time of shot is eliminated by barrel finishing so as to form the smooth sliding surfaces 10a, 13a (for example, 1mumRz and less), it is possible to suppress generation of abrasive loss of the counterpart sliding surface.

摘要： PURPOSE:To provide a sintered alloy for an intake valve seat excellent in corrosion resistance to lead compounds and excellent in durability even if lead- contg. fuel is used. CONSTITUTION:By weight, 5 to 25% Pb is infiltrated into a sintered allay obtd. by dispersing hard grains contg. 5 to 25% Cr, 2 to 5% Si and 20 to 40% Mo, and the balance Ni into the structure of a matrix contg. 0.2 to 2.0% C and 1.0 to 7.O% Ni and/or Co, and the balance Fe with impurity elements. By Ni and/or Co in the matrix structure, its corrosion resistance to lead compound improves, and because the hard grains are constituted of an Ni base alloy, the hard grains are rigidly connected to the matrix structure by the diffusion of Ni, and its durability to lead-contg. fuel is made excellent. Moreover, by the combination with a stellite series built-up allay, excellent wear resistance and attackability on the mate can be obtd.

摘要： PURPOSE: To surely fix a cylindrical shaft and a projected member to make them in one body, by loosely fitting the projected member to the hollow cylindrical shaft with a soldering material, and then, by expanding the cylindrical shaft with hydraulic pressure, and, at the same time, rotating the cylindrical shaft and the projected member relatively.
CONSTITUTION: A projected member 2, such as cam piece, etc., whose inner surface is coated with a soldering material 4, is loosely fitted to the outer circumference of a hollow cylindrical shaft 1, such as cam shaft, etc., and the projected member 2 is clamped with a metallic mold 3. Then pressure is applied to the inside of the cylindrical shaft 1 and the shaft 1 is expanded by supplying high pressure water from a high pressure water source 6 connected to the cylindrical shaft 1, and the projected member 2 is pressure-contacted to the shaft 1 through the soldering material 4. When the cylindrical shaft is rotated at a high speed under this condition, the soldering material 4 gradually melts due to the frictional heat. When the rotation is stopped under the condition where the shaft is expanded, the molten soldering material 4 is naturally cooled, thus the projected member 2 and the cylindrical shaft 1 are firmly fixed to each other.

摘要翻译：目的：将圆柱形轴和突出构件固定在一体，通过用焊接材料将突出构件松动地装配到中空圆柱轴上，然后通过用液压膨胀圆柱轴，并在同时，相对地旋转圆柱形轴和凸出构件。构成：内表面涂有焊料4的突出构件2，例如凸轮片等松动地安装在诸如凸轮轴等的中空圆柱形轴1的外圆周上，并且突出构件2用金属模具3夹紧。然后，通过从连接到圆柱形轴1的高压水源6供应高压水，将压力施加到圆柱形轴1的内部，并且轴1膨胀，并且突出构件2通过焊接材料4与轴1压力接触。当在该条件下圆柱轴高速旋转时，焊接材料4由于摩擦热而逐渐熔化。当轴在膨胀的状态下旋转停止时，熔融焊接材料4自然冷却，因此突出构件2和圆柱形轴1彼此牢固地固定。

摘要： PROBLEM TO BE SOLVED: To maintain a smooth motion of valve driving system which retains a shim, swingable in accordance with the cam profile of three dimensional cam, by reduction of friction coefficient enabled by forming the radius of curvature of sliding surface of shim bigger than that of guide groove fixed to the valve lifter. SOLUTION: At low speed rotation of internal combustion engine, cam shaft shifts leftwards and cam profile for slow speed rotation at the right side of three dimensional cam 1a contacts with flat surface of shim 2 consequentially, and cam nose 1c pushes shim 2 which swings in a small angle in accordance with the rotation of cam 1a synchronously, and valve 5 opens and stubs through valve lifter 4 in small working angle and lifting distance of the valve accordingly. In this case, oil is supplied adequately to the space between the sliding surface of shim 2a and guide groove 3a by forming the radius of curvature of sliding surface 2a, facing parallel to the direction of cam shaft, bigger than that of guide groove 3a facing to the same direction. Thus, frictional force arisen from the swing of shim 2 is reduced and smooth motion is maintained.

摘要： PURPOSE:To improve resistance to fatigue peeling and resistance to wear of the cam and the roller of a value system device. CONSTITUTION:A cam 10 is fixed on a cam shaft 12, and a roller 13 on a roller lifter 11 comes into contact with the cam 10 to transmit its rotary motion to the cam. The motion of the roller lifter 11 is transmit to open and close an intake valve 5 or an exhaust valve 7 of an internal combustion engine. When the roughness of the cam 10-surface 10a in contact with the roller is below 8muRz, little fatigue separation is generated on the roller 13-surface 13a in contact with the cam. Further, when the roughness of the roller 13-surface 13a in contact with the cam is below 1muRz, wear of the cam 10-surface 10a in contact with the roller is reduced.
