    • PURPOSE:To simplyfy and quicken the work by employing a roller assembling zig comprising a retainer, inner ring and a push ring. CONSTITUTION:A roller assembling zig is comprising a retainer 7, an inner ring 8 and a push ring 9. A washer 10' is fitted over the retainer 7 while a roller 3 and a needle 6 are mounted then a washer 10 is applied. Thereafter an inner ring 8 is pressure inserted into the opening at the flange side 11 of the retainer 7 of an unitized roller and secured. Here the foot section 16 of the push ring 9 is contacted with the washer 10'. When applying the other opening of the retainer 7 against a spider shaft 4 then holding the inner ring 8 to push the push ring 9 toward the spider shaft 4, the washer 10, needle 6, roller and washer 10' are sequentially transferred to the spider shaft 4.
    • 目的:通过使用包括保持器,内圈和推环的滚子组装Zig来简单地加快工作。 构成:滚子组装引弧包括保持器7,内圈8和推环9.在安装辊3和针6的同时,将垫圈10'装配在保持器7上,然后施加垫圈10。 此后,内环8被压入插入到组合辊的保持器7的凸缘侧11处的开口中并被固定。 这里,推环9的脚部16与垫圈10'接触。 当将保持器7的另一个开口施加在一个蜘蛛轴4上,然后保持内圈8将推环9推向星形轮轴4时,垫圈10,针6,滚子和垫圈10'依次传送到蜘蛛 轴4。

    • PROBLEM TO BE SOLVED: To provide a tripod type constant velocity joint that obtains a desired shape with high accuracy even if the outer peripheral surfaces of a plurality of rollers are simultaneously processed, and provide a manufacturing method thereof.SOLUTION: A roller 30 includes an outer peripheral rolling surface 32 molded by simultaneous processing in a state of contacting the end surfaces of a plurality of rollers 30 with each other; and a projection 35 projecting in an axial direction from the axial end of the outer peripheral rolling surface 32. The projection 35 has a projection end surface 35a contacting the end surfaces 33, 35 of adjacent rollers 30 during grinding of the outer peripheral rolling surface 32, and forms an axial gap B between the ends of the outer peripheral rolling surfaces 32 of adjacent rollers 30 in a state of being contacted with the projection end surface 35a. Further, the projection 35 has a gap D from and to a tool 100 during processing of the outer peripheral rolling surface 32.
    • 要解决的问题:为了提供即使多个辊的外周面被同时加工也可以高精度地获得所需形状的三球销型等速万向节,并且提供其制造方法。辊子30包括: 在与多个辊30的端面接触的状态下通过同时处理而成型的外周滚动面32; 以及从外周滚动面32的轴向端部沿轴向突出的突起35.突起35在外周滚动面32的研磨期间具有与相邻的辊30的端面33,35接触的突出端面35a 并且在与突出端面35a接触的状态下在相邻的辊30的外周滚动面32的端部之间形成轴向间隙B. 此外,突出部35在外周滚动面32的加工中具有与工具100的间隙D。

    • PROBLEM TO BE SOLVED: To provide a small configuration of an outer member of a tripod constant velocity joint to which a resin boot can be easily assembled.
      SOLUTION: Three track grooves 22a to 22c separated from each other by 120° are formed on the inner wall surface of a bottomed cylindrical part 12 of the outer member 14. Each of the track grooves 22a-22c comprises a bottom wall 24 formed in the direction extending along the outer peripheral surface of the bottomed cylindrical part 12 and two side walls 26, 26 raised in substantially vertical direction from the bottomed wall 24 and opposed to each other. Hardened layers 28 having a thickness of 0.8-3 mm are formed near the side walls 26, 26 by induction hardening. Since induction hardening is not applied to the bottom wall 24, no hardened layer 28 is formed near the bottom wall 24.
