摘要： A crankshaft bearing for internal-combustion engines is provided in an internal-combustion engine housing made of a light metal alloy and comprises a bearing bore for a crankshaft journal of a crankshaft. The crankshaft bearing is provided with a device that reduces the increase in bearing play that occurs during the operation of the internal-combustion engine. This device includes a compensating element which is provided between the bearing bore and the crankshaft journal and has a relatively high coefficient of expansion.

摘要： The crankshaft bearing of a multicylinder internal combustion engine has an upper and a lower bearing part, as well as upper and lower bearing brackets with bearing bores connected therewith, in which brackets the main bearing pins of a crankshaft are mounted. The main bearing pins of the crankshaft are supplied with lubricant through oil grooves in the bearing bores. In order to guide the oil escaping from the bearing locations, which oil is flung-off by the rotating crankshaft cheeks, oil grooves are provided on the lateral surfaces of the bearing brackets. The groves are open on their radial interiors and drain downward in the installed position. This prevents severe foaming of the oil, since the oil flung-off the crankshaft can be captured directly and guided. The residence time of the oil in the crank chamber is reduced so that the oil flows more rapidly back into the oil pan and churning losses are reduced.
摘要翻译： 多缸内燃机的曲轴轴承具有上和下轴承部分以及与轴承孔连接的上部和下部轴承支架，其中安装有曲轴的主轴承销。 曲轴的主轴承销通过轴承孔中的油槽供给润滑剂。 为了引导从轴承位置排出的油，哪个油被旋转的曲轴颊部排出，在轴承座的侧表面上设置有油槽。 树丛在其径向内部开放，并在安装位置向下排水。 这防止了油的严重起泡，因为可以直接捕获曲轴上的油并被引导。 油在曲轴室中的停留时间减少，使得油更快地流回到油盘中，并且减少了搅拌损失。

摘要： The crankshaft bearing for an internal combustion engine consists of two bearing sections bolted together, in which an insert made of a ferrometallic material is embedded in a casting made of a light metal alloy. The inserts consist of shaped molded parts with openings and thickenings as well as a semicircular carrier that receives the respective part of the bearing bore. The inserts are traversed by the bearing bolts, which on one side abut the outer bolt surfaces on the casting of one bearing section and are bolted into the casting of the other bearing section.
