摘要： An oil pump comprises a rotation shaft having an eccentric part, a needle roller bearing supporting the eccentric part of the rotation shaft, a tappet abutting on the outer ring of the needle roller bearing and arranged in a radial manner, a plunger arranged on the tappet and reciprocated by the rotation of the rotation shaft, and a balancer arranged on both ends of the eccentric part. The balancer has a large diameter part and a small diameter part and when the large diameter part is arranged so as to face the direction opposite to an eccentric direction, the rolling space of a roller can be projected from an axial direction through the balancer.
摘要翻译：油泵包括具有偏心部的旋转轴，支撑旋转轴的偏心部的滚针轴承，抵靠滚针轴承的外圈并以径向方式配置的挺杆，布置在挺杆上的柱塞并且通过旋转轴的旋转而往复运动，以及设置在偏心部的两端的平衡器。平衡器具有大直径部分和小直径部分，并且当大直径部分布置成面向与偏心方向相反的方向时，辊的滚动空间可以从轴向通过平衡器突出。

摘要： A steel-made rolling-contact shaft with a joint claw improved in both the rolling contact fatigue life at the raceway and the static fracture strength (torsional strength) at the claw includes a joint claw at one end, and has a portion of the outer cylindrical surface functioning as a raceway of a needle roller qualified as a rolling element of a needle bearing. The joint claw is subjected to tempering by induction heating. A nitrogen-enriched layer is formed at the surface layer of the rolling-contact shaft with a joint claw. The grain size number of austenite grains in the nitrogen-enriched layer exceeds number 10. The hydrogen content of the rolling-contact shaft with a joint claw is not more than 0.5 ppm.
摘要翻译：具有改善滚道的滚动接触疲劳寿命和爪的静态断裂强度（扭转强度）两者的具有接合爪的钢制滚动接触轴包括在一端的接合爪，并且具有外部的一部分作为滚针轴承的滚动元件的滚针的滚道的圆柱面。接合爪通过感应加热进行回火。在滚动接触轴的表面层处，用接合爪形成富氮层。氮富集层中的奥氏体晶粒的粒径数超过10个。具有接合爪的滚动接触轴的氢含量不大于0.5ppm。
