摘要： Fastener joints induce static pre-stresses into a fastener that clamps the joint in a magnitude equal and direction opposite from bending stresses induced in the fastener by application loading. Such joints include angling the bolts seats of a connecting rod bearing cap inwardly, creating a relief at the bolted interface between the cap and the rod adjacent to the main bore of the connecting rod or skewing the threaded holes in the rod body inwardly as they extend from the bolted joint faces.
摘要翻译：紧固件接头将静态预应力引入到紧固件中，该紧固件以与通过施加载荷在紧固件中引起的弯曲应力相等和方向相反的方向夹紧接头。这种接头包括向内倾斜连杆轴承盖的螺栓座，在盖和与连接杆的主孔相邻的杆之间的螺栓连接处形成凹槽，或者当杆体延伸时向内倾斜杆体中的螺纹孔从螺栓连接面。

摘要： A forging die tool set defines a cavity and includes a core rod in the cavity for shaping a void in a work piece. The core rod extends in a direction in which the work piece is introduced, compressed, and ejected from the cavity. The core rod includes an upper portion and a lower portion. The upper portion has a cross sectional shape that forms a certain shape in the work piece and a radially tapered section that tapers toward the lower portion of the core rod. The lower portion also has a cross sectional shape that forms a certain shape in the work piece, and the cross sectional shape of the upper portion differs from the cross sectional shape of the lower portion, the lower portion being a more wear resistant shape characterized by larger radii and the upper portion being a finishing shape with smaller radii for shaping the final form of the forged work piece.
摘要翻译：锻造模具工具组限定了空腔，并且在空腔中包括用于使工件中的空隙成形的芯棒。芯棒沿着工件被引入，压缩并从空腔喷出的方向延伸。芯棒包括上部和下部。上部具有在工件中形成一定形状的横截面形状和朝向芯棒的下部逐渐变细的径向锥形部分。下部还具有在工件中形成一定形状的横截面形状，上部的横截面形状与下部的截面形状不同，下部具有更耐磨损的形状，其特征在于，较大的半径，上部是具有较小半径的精加工形状，用于成形锻造工件的最终形式。

摘要： The invention provides a method of manufacturing a ferrous monolithic component and the component that results from the method. The method of the invention utilizes selective rapid cooling of the portion of the component that is desired to have increased strength and selective controlled cooling of the portion or portions which are desired to be more machinable. The controlled cooling may include cooling, re-heating and re-cooling. The result is a component with local high strength in the rapidly cooled zones and locally altered metallurgical properties to improve machinability in the more slowly cooled zones.

摘要： A one-way clutch with an outer race and an inner race is disclosed. One of the races includes at least one pawl and an engagement member for holding the at least one pawl in engagement with ratchet teeth on the other race. The contact surface of the at least one pawl or the ratchet teeth is an arcuate shape for improved load distribution. The arcuate contact surface has a radius of curvature that is greater than a radius of curvature at corners adjacent to the arcuate contact surface.
