摘要： PROBLEM TO BE SOLVED: To improve abrasion resistance by suppressing the abrasion of a pin hole and a pin to the utmost. SOLUTION: A scent chain 1 is constituted by connecting many link plates 2 (2a1, 2a2, 2b1, and 2b2) formed of a pair of tooth parts and pin holes by pins 3 inserted into the pin holes, and also arranging guide links 4 in the outermost sides of the link plates 2 (2a1, 2a2, 2b1, and 2b2). In this case, a surface roughness of the pin holes and the pins 3 is made 0.5 μm or less, a shearing surface length of the pin holes is made 90% or more of the axial directional lengths of the pin holes, and also the hardened layers of vanadium carbide are formed on the pins 3 to make a thickness of the hardened layers 20 μm or more. Moreover the plate thickness t1 of the outermost side link plate 2b1 of link rows 6 is made larger than the plate thickness t2 of other link plates 2b2 of the link rows 6, and also the plate thickness t1, of the center link plate 2a1 of guide rows 5 is made larger than the plate thickness t2 of other link plates 2a2 of the guide rows 5.

摘要： PROBLEM TO BE SOLVED: To increase a lubrication effect of a pin which is slidably engaged with a pin hole of a link plate of a chain.
SOLUTION: The pin 13 is relatively rotatably engaged with the pin hole 11a which is formed on the outside link plate 11o of the chain, and four spiral grooves 13b are formed on the outer peripheral surface 13a of the pin 13. Since the pitch P of the adjacent spiral grooves 13b of the pin 13 in the axis A direction is made smaller than or equal to the width Bo of the pin hole 11a of the outside link plate 11o in the axis A direction, a lubrication effect can be increased by placing at least one spiral groove 13b so as to be opposite on an arbitrary busbar on the inner peripheral surface of the pin hole 11a without taking into consideration the phase of the pin 13 at the time of assembling. When the radius of the pin 13 is R, and a relative rotation angle with respect to the outside link plate 11o is θ, the pitch P' of the adjacent spiral groove 13b in the circumferential direction is made smaller than or equal to Rθ. Thus, the lubrication effect can be further increased by making one spiral groove 13b pass all positions within sliding ranges of both the adjacent grooves.

摘要翻译：要解决的问题：增加与链条的链板的销孔可滑动地接合的销的润滑效果。解决方案：销13与形成在链条的外链板11o上的销孔11a相对旋转地接合，并且在销13的外周表面13a上形成四个螺旋槽13b。由于使销13的相邻螺旋槽13b的轴线A方向的间距P小于或等于外侧连杆板11o的轴孔11a的轴线A方向的宽度Bo，能够提高润滑效果通过在销孔11a的内周面上的任意母线上设置至少一个螺旋槽13b，而不考虑组装时的销13的相位。当销13的半径为R并且相对于外侧连杆板11o的相对旋转角度为θ时，相邻的螺旋槽13b的圆周方向的间距P'小于或等于Rθ。因此，通过使一个螺旋槽13b通过两个相邻槽的滑动范围内的所有位置，可以进一步提高润滑效果。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To improve the respondability by mounting a relief valve on a fixing member unmovable to a plunger. SOLUTION: A relief valve 5 is inserted into a valve insertion hole formed from a chain side of an insertion part 3a of a tensioner body 3. By mounting the relief valve 5 on the tensioner body 3 unmovable to a plunger 7, the tensioner can be made compact and light-weighted in comparison with a case when the relief valve 5 is mounted on the plunger 7. That is, the projecting movement and the retreating movement of the plunger 7 can be quickly performed, and the responsiveness of the hydraulic tensioner to the displacement caused by the loosening and vibration of a chain can be improved. A relief spring 5e of the relief valve 5 is not affected by the projecting movement and the retreating movement of the plunger 7, the relief characteristic determined corresponding to the valve opening force determined on the basis of the set load of the spring 5e can be stably maintained.

摘要： PROBLEM TO BE SOLVED: To provide a silent chain by which the elongation due to the wear of the pin hole of the link plate is suppressed.SOLUTION: The foreign matter generated between the pins 9 and the pin holes 11 moves to the end sides of the pin holes 11 as shown by an arrow in Fig.9 and is discharged to the outside of the silent chain 1 from the gaps between both second link plates 5 and the gaps between the first link plate 2 and the second link plate 5 because the end diameter De is larger than the middle diameter Dc of the pin holes 11 and the contour line CL of the cross-section exhibits an arcuate shape. The pin holes 11 almost do not wear even though the pins 9 and the pin holes 11 relatively rotate because the foreign matter is held in the gaps 41 to 43 of the end sides of the pin holes 11 even when the foreign matter is not discharged to the outside of the silent chain 1.
