Abstract

往复式发动机立柱的端壁（４），接受十字头轴颈在法线方向上作用的力，并支承在一个由侧壁（６）和外壁（３）形成的箱形的部件上。侧壁（６）沿垂直方向向上向端壁（４）的自由端伸展，因此，箱形部件在法向力作用最大的区域，即靠近活塞运动的上死点附近增宽，但发动机长度并不因此而增大。箱形部件的宽度增大可以减少端壁、尤其是端壁（４）的端部因负荷造成的变形。

Description

支承十字头导杆滑轨的立柱
本发明有关往复式发动机中支承十字头导杆滑轨的立柱，立柱有外壁在底板和盖板之间倾斜伸展，在整个高度上伸展的侧壁将垂直端壁与外壁相连，端壁在它们的相对的面上的一部份高度上，有导杆滑轨，把作用在十字头轴颈法线方向上的力，传递到立柱上去。
在传统上，为了接受作用在法线上，并且沿垂直于往复式发动机（特别是些油机）十字头导杆滑轨方向被传递到立柱或支撑件上的力，不仅需要在导杆滑轨的高度上配置水平的横向加强肋，或在端壁和侧壁端部之间，成锐角地设置垂直伸展的加强壁（见瑞士专利CH-PS625，603号）。可以发现上文叙述的结构很昂贵。
并且，往复式发动机要求结构非常紧凑，要求气缸之间有非常短的距离。该距离取决于必要的主轴承长度，下连杆轴承长度，和两个曲柄臂尺寸的总和。因此，假如要求不“浪费”发动机的长度，侧壁在下部，靠近曲轴附近，必须非常靠近。
因此本发明的目的，是简化设置支承导杆滑轨的装置的轮廓结构，而不造成端壁过大的变形，也不增加发动机的长度。因此，根据本发明，成对地支承一个端壁的侧壁，向着端壁的端部倾斜伸展。
当然垂直作用在导杆滑轨上的，从而也作用在端壁上的力，在活塞运动的上死点处最大，按本发明提出的侧壁结构，在这区域中形成一个由端壁，外壁和两面侧壁组成的相对宽的箱体。在活塞的上死点位置附近，侧壁在端壁自由端附近支承端壁，使变形保持在一个相对小的限度内。
下文将参照一个实施方案和附图，对本发明作更为详尽的叙述。附图内容如下：
图1为柴油发动机中一个单立柱，沿图2中之Ⅰ-Ⅰ线的截面示意图;
图2为发动机相邻两立柱沿图1的Ⅱ-Ⅱ线的俯剖视图，两立柱间有十字头;
图3为图2沿Ⅲ-Ⅲ线的剖视图。
一个有已知结构的立柱，例如由钢板焊接构成，该立柱有底板2和两边倾斜外壁3及垂直端壁4联接构成，形成两个垂直方向上呈梯形的架体。架体之间由一个共同的盖板5连接。侧壁6在外壁3和侧壁4之间使其成为一个完整的梯形架体。联接杆或双头螺栓7或类似零件（图2）放在侧壁6之间，用预应力固定发动机气缸盖（图中未予示出）。
用轴瓦14将曲轴16安装在基板1内，轴瓦14有上半部和下半部，轴瓦上安放一个轴承盖15。
从图3中可以看出，气缸所必须有的发动机的长度m主要包括两侧主轴承14的长度的一半h/2，连杆20的下轴承18的长度S和两个曲柄臂17的厚度d。前面已经提过，每一个气缸所必须有的发动机的长度要求非常小。
在两端壁4之间的中间部份处，有一个中间壁8代替侧壁6，中间壁8的下端部设有一个横向支承板9。从图2中可见，两个立柱的端壁4的相对的两个面上，形成十字头轴颈11的滑动件10的导杆滑轨，十字头轴颈11用已知的方式和活塞杆12连接，并安装在轴承壳13内。
根据本发明，两侧壁6在底部互相离开一段仅可供系杆或双头螺栓或类似零件7能从里面通过的距离。侧壁6倾斜放置，向上互相远离，以便在一个与上死点相毗连的区域里（这个区域在图1和3里大约为十字头所在的位置）在端壁4的自由端附近支承端壁4。因此壁3，4和6在上述区域中形成一个相对宽的刚性“箱体”，而不使发动机的长度m增大。
间隔壁19设置在侧壁6之间的空间内，加强“箱体”，以便在高负荷的区域中提高面积相当大的侧壁的刚度。
