A low speed diesel engine main bearing oil inlet structure, the bearing seat is arranged on the base and the bearing cover arranged on the bearing seat by a hydraulic bolt and nut, the main bearing installed in the bearing seat, also includes an oil inlet pipe, one end of the main shaft of the oil inlet pipe and the bearing seat through the bolt hole., and the other end is communicated with the top of the bearing cover, and extends to the main bearing. The lubricating oil can flow from the bearing seat through the bolt hole to the oil passage at the top of the bearing cap and then into the main shaft tile to achieve the purpose of lubrication. The utility model utilizes the existing through bolt holes into the oil, in addition to eliminating the main bearing cover at the top of the pipeline outside the pipe layout, shorten the pipeline and other structural arrangements for the diesel engine to save space saving pipe. The new oil inlet structure can also save the connection of bolts and nuts at most of the tubing flange connections, thus reducing the risk of falling to the crankcase due to nuts and gaskets during the installation of the oil pipe.

一种低速柴油机主轴瓦进油结构
本技术涉及一种柴油机结构的进油方式,具体涉及一种低速柴油机主轴瓦润滑油进油方式,属于柴油机
技术介绍
低速柴油机一般包括有曲轴、主轴瓦、机座、轴承座和轴承盖,轴承座安装于机座中,轴承盖通过液压螺栓和螺母安装在轴承座上,主轴瓦安装在轴承座中。主轴瓦为薄壁轴瓦,由钢背和合金组成,合金面与曲轴接触。现有主轴瓦的滑油进油方式一般是从主滑油管引出一条主轴承润滑支管油路,然后将支管连接到轴承盖顶部油孔进油。现有的进油方式,需要布置管路,在柴油机中会占用一定的空间。油管连接处是法兰通过螺栓螺母连接。在油管安装过程或曲轴运转过程中,螺母垫片等可能松动掉落到曲轴箱,产生事故隐患。
技术实现思路
本技术的目的在于克服现有技术的不足,提供了一种低速柴油机主轴瓦进油结构,该进油方式大大缩短了机体内部布置管路,利用现有的贯穿螺栓孔和轴承盖顶部外接油管实现进油。本技术技术解决方案如下:一种低速柴油机主轴瓦进油结构,轴承座安装于机座中,轴承盖通过液压螺栓和螺母安装在轴承座上,主轴瓦安装在轴承座中,是由钢背和合金组成的薄壁轴瓦,其中合金面与曲轴接触。曲轴运转需要一定的润滑油保证润滑,其特点在于:还包括进油管道,该进油管道的一端与所述的主轴承座上的贯穿螺栓孔相连,另一端与轴承盖顶部相连通,并延伸至主轴瓦。润滑油可以从轴承座贯穿螺栓孔流到轴承盖顶部油道然后到主轴瓦中,进而达到润滑的目的。与现有的进油方式结构相比,本技术取得了如下技术效果:1)与现有的从轴承盖顶部油管进油方式相比,现在利用贯穿螺栓孔进油,省去了除主轴承盖顶部油管以外的油管布置,缩短了管路,为柴油 ...
