Embodiment Construction

[0010] The structural principle of the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments. The oil pump system integrated with the engine body, the specific structural scheme is: the body cavity 2 of the oil pump is arranged on the engine body 1, and the driving shaft 4 and the driven shaft 4 and the driven shaft 4 are respectively arranged on the bushings of the body boss 3 in the cavity. Shaft 5, driving shaft and driven shaft are inlaid with driving gear 6 and driven gear 7 respectively. The right inner wall of the concave cavity of the body is provided with an oil inlet 8, which communicates with the oil passage 9 at the bottom of the body, and the left side of the concave cavity of the oil pump body is provided with an oil outlet 10 connected to the main oil passage (such as figure 1 ). The oil pump casing 11 is provided with a casing cavity 12 having the same shape as the body cavity, and the cas...

Abstract

The invention discloses a fuel pump system integrated with an engine body. The structure is that an engine body recessed cavity of a fuel pump is arranged on the engine body, and a casing recessed cavity identical with the engine body recessed cavity in shape is arranged on a fuel pump casing. A driving shaft and a driven shaft are respectively arranged on boss shaft sleeves in the recessed cavities, and a driving gear and a driven gear are respectively embedded in the driving shaft and the driven shaft. The driving shaft with the driving gear penetrates through the boss shaft sleeve of the fuel pump casing to be connected with a fuel pump gear outside the fuel pump casing. The fuel pump casing and the engine body recessed cavities are fastened and sealed through bolts and rubber rings to form a complete fuel pump working cavity. A large portion of the fuel pump working pump occupies space in the engine body to enable structure outside the fuel pump to be very small. When identical pressure and flow in a main oil channel are achieved, overall dimension of the engine is remarkably reduced. Therefore, the matching difficulty of the engine and a whole vehicle can be reduced, and large maintenance space is retained for the whole vehicle. The structure can be widely applied to any engine due to the fact that the system is simple and compact in structure.

Description

technical field [0001] The invention belongs to engine components, in particular to an oil pump system device integrated with a machine body. Background technique [0002] The main task of the lubrication system of the engine is to send the engine oil to the surface of each moving part, so that the friction pair is in a lubricated state, and take away the heat generated by friction while reducing wear. Diesel engines use oil pumps as the power source for oil pressure and flow in the lubrication system. The oil pump assembly of a general engine is to connect the pump body and the filter as a whole and install it directly in the engine oil pan. This setting structure requires that the oil pan of the engine must have sufficient capacity and volume to load the oil pump, and the size of the oil pan is required to be large, so the volume of the engine is also large. The larger volume of the oil pan is very unfavorable to the matching of the whole vehicle, especially the design a...
