Problems solved by technology

[0002] In the traditional technology, a bearing support installation structure is provided on the structure supporting the camshaft formed between the body of the engine and the crankcase. In order to deliver lubricating oil to the camshaft support journal and bearing part, usually by setting an internal oil passage or Pipes and other forms are connected to the shaft groove and the oil injection port of the oil pump, and the high-pressure lubricating oil is delivered from the oil pump to the shaft groove to form a lubrication structure between the shaft and the bearing. The oil circuit is complicated, and some oil mist lubrication is also used, but It is easy to cause the problem of insufficient lubricating oil in the bearing part

Abstract

The invention relates to installation of a diesel engine camshaft and a lubrication structure. The lubrication structure comprises an engine body, a crankcase cover, a camshaft, a cylinder block, a camshaft wheel gear, a cylinder head cover and a cylinder head, wherein the crankshaft is directly supported in a crankshaft supported hole corresponding to the engine body and the crank case cover by support shaft necks at two ends; the lubrication oil filler of the cylinder head cover is communicated with the lubrication oil inlet passage of the cylinder head; the lubrication oil inlet passage of the cylinder head is communicated with the lubrication oil inlet passage of the engine body by a push rod casing; and the support shaft necks at two ends of the crankshaft are lubricated by the lubrication oil in the crankcase introduced from the oil duct and the oil groove arranged in the supported hole. The invention not only meets the installation and lubrication requirements of the crankshaft, but also simplifies the installation of parts, reduces the cost, and has simple structure and reasonable configuration.
