Lubricating oil circuit system of rocker arm type side cam gasoline engine

Abstract

The invention discloses a lubricating oil circuit system of a rocker arm type side cam gasoline engine, which comprises a crankcase body, a crankshaft, a cylinder head, a camshaft and a cylinder head cover. The shaft is installed in the camshaft groove of the crankcase body. A center hole is arranged in the installation end along the axis. A half shaft hole is arranged radially on the installation end close to the end face. The oil return hole, the position of the cylinder head corresponding to the camshaft groove is provided with the intake push rod hole and the exhaust push rod hole, the cylinder head chamber is formed between the cylinder head and the cylinder head cover, the intake push rod hole and the exhaust push rod hole communicated with the cylinder head chamber. The center hole, half shaft hole, camshaft groove, intake and exhaust push rod holes, and cylinder head chamber form an oiling system, and the cylinder head chamber, intake push rod hole, camshaft groove, half shaft hole and oil return path form an oil return system, thus forming a complete lubricating oil circuit system to lubricate the moving parts of the engine and ensure the normal operation of the engine.

Description

technical field [0001] The invention belongs to the technical field of engine lubrication, and in particular relates to a lubricating oil passage system for a rocker arm type side cam gasoline engine. Background technique [0002] An engine is a machine that converts other forms of energy into mechanical energy. In order to ensure the normal operation of the engine, a lubricating structure is usually provided in the engine so that each moving part in the engine can be effectively lubricated. However, for the gasoline engine with the rocker arm type side camshaft, the lubricating oil circuit of the existing crankcase and crankshaft is adopted. This method increases the difficulty of casting the crankcase body, and the residual sand in the oil hole is not easy to remove, which may easily lead to blockage of the lubricating oil or impurities in the lubricating oil, affecting the lubricating effect. Contents of the invention [0003] The invention intends to provide a lubric...
