摘要： A double row thrust needle roller bearing, which can suppress differential slippage of the needle rollers under severe working conditions to improve its durability without increasing processing cost for majority variety/minority lot production, has a plurality of needle rollers (2) arranged in at least two rows in a radial direction and an annular cage (3) formed with a plurality of pockets (4) to hold the needle rollers (2). Each pocket (4) is formed in a rectangular configuration with a length of its radial side longer than that of each needle roller (2). A length of the pockets circumferential side is larger than the diameter of each needle roller (2). Each needle roller (2) is held within each pocket (4) of the cage (3) by nailed portions (5). The nailed portions (5) are formed near radially extending side walls (4a) of the pockets (4) at either sides of each needle roller (2) along its longitudinal direction. The nailed portions (5) are formed by plastically deforming the cage (3) at a substantially middle portion of the longitudinal length of the needle roller (2). Thus, each nailed portion (5) overhangs into the pocket (4) over the needle roller (2).
摘要翻译：一种双列推力滚针轴承，其能够抑制在恶劣工作条件下的滚针的不均匀滑动，以提高其耐久性而不增加大多数品种/少数批量生产的加工成本，具有多个至少布置在其中的滚针（2）在径向方向上有两排，以及形成有多个保持滚针（2）的凹穴（4）的环形保持架（3）。每个口袋（4）形成为其径向侧的长度比每个针辊（2）的长度长的矩形构造。凹口周向侧的长度大于每个滚针（2）的直径。每个滚针（2）通过钉部（5）保持在保持架（3）的每个凹部（4）内。钉子部分（5）沿其纵向方向形成在每个滚针（2）的两侧的凹穴（4）的径向延伸的侧壁（4a）附近。钉部（5）通过使滚针（2）的纵向长度的大致中间的部分使保持架（3）发生塑性变形而形成。因此，每个钉部分（5）在针辊（2）上方伸出到袋（4）中。
