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。

摘要： A variable stroke characteristic engine in which a piston (11) and a crankshaft (30) are linked to a control shaft (65) via a variable stroke link mechanism (LV), and the variable stroke link mechanism (LV) is operated by a hydraulic actuator (AC) that drives the control shaft (65) to thus make the stroke travel of the piston (11) variable, in which the hydraulic actuator (AC) is formed from a housing (HU), a cover member covering an aperture of the housing (HU), a vane case provided integrally within the housing (HU), and a vane shaft (66) housed within the vane case, and the vane shaft (66) is formed integrally with the control shaft (65). The number of components of the actuator (AC) can be decreased, and its ease of assembly can be improved.
