摘要： A valve-operating system for an internal combustion engine includes cam followers which have cam abutment portions abutting against valve-operating cams provided on a camshaft and which are swingably carried in an engine body and operatively connected to engine valves biased in a closing direction by a valve spring. The cam followers are biased in a direction of abutment of the cam abutment portions against the valve-operating cams by a resilient biasing means different from the valve spring. A resilient biasing means includes a pull rod connected at one end thereof to the cam follower, and a compression coil spring interposed between the other end of the pull rod and the engine body to pull the pull rod to bias the cam follower in a direction of abutment of the cam abutment portion against the valve-operating cam. Thus, the resilient biasing means is constructed to be compact, leading to an increase in degree of freedom of the design of the structure of the valve-operating system.
摘要翻译：用于内燃机的阀操作系统包括凸轮从动件，其具有与设置在凸轮轴上的阀操作凸轮邻接的凸轮抵接部，该凸轮抵接部可摆动地承载在发动机主体中并且可操作地连接到以关闭方向偏置的发动机气门阀门弹簧。凸轮从动件通过与阀弹簧不同的弹性偏置装置沿凸轮抵接部分抵靠阀操作凸轮的方向偏置。弹性偏置装置包括在其一端连接到凸轮从动件的拉杆和插入在拉杆的另一端和发动机主体之间的压缩螺旋弹簧，以拉动拉杆，以将凸轮从动件沿着凸轮抵接部分与阀操作凸轮的邻接。因此，弹性偏压装置被构造成紧凑的，导致阀操作系统的结构设计的自由度增加。

摘要： A needle roller bearing comprises an outer ring having a plurality of outer ring members split by split lines extending in an axial direction of the bearing, a plurality of needle rollers arranged on an orbit surface of said outer ring so that they can roll thereon, and a cage holding the needle rollers at intervals. The outer ring member has a projection serving as a positioning engaging part which engages with a housing for positioning, and an engaging click protruding from an axial end of the outer ring member inward along a diameter to prevent the cage from moving in an axial direction, in positions shifted from its circumferential center.

摘要： In a balance shaft for engine balancing systems for canceling an unbalance force of an engine, a journal portion of the balance shaft is provided with a recess on a side remote from the gravitational center of the counter weight, and a rib extends axially across this recess along a radial plane between full circular axial end portions of the journal portion to compensate for the reduction in the bending rigidity of the balance shaft due to the provision of the recess. The recess reduces the weight or mass of the balance shaft, and this recess does not diminish the performance of the bearing because the bearing load is essentially due to the unbalanced mass of the counter weight portion, and the recessed part of the bearing portion receives a significantly smaller part of the bearing load than the opposite side of the bearing portion. The recessing also contributes to increasing the eccentricity of the gravitational center of the associated part.
摘要翻译：在用于消除发动机的不平衡力的发动机平衡系统的平衡轴中，平衡轴的轴颈部分在远离配重的重力的一侧设置有凹部，并且肋沿着该凹部轴向延伸沿着轴颈部分的全圆形轴向端部之间的径向平面，以补偿由于设置凹部而导致的平衡轴的弯曲刚度的降低。该凹部减小了平衡轴的重量或质量，并且该凹部不会降低轴承的性能，因为轴承负载基本上是由于配重部分的不平衡质量，并且轴承部分的凹部接收轴承负载的一部分显着小于轴承部分的相对侧。凹陷也有助于增加相关部件的引力中心的偏心率。
