Abstract

The utility model relates to a rotor lubricant pump, in particular to a rotor lubricant pump which is directly transmitted by the flat square of an engine crankshaft and is matched with a CA400 engine. The rotor lubricant pump consists of a pump body, a pump cover, an internal rotor and an external rotor; the external rotor is arranged in a rotor hole of the pump body; and the external rotor is in movable fit with the rotor hole of the pump body. The internal rotor is arranged in a cavity of the external rotor; and the cavities of the internal rotor and the external rotor are in movable fit with each other. The pump cover is arranged on the pump body of the internal rotor part and the external rotor part by a screw; and after the pump cover is installed, the rotor is ensured to rotate flexibly. The shaft hole of the internal rotor is a flat square hole; two beelines of the flat square hole are provided with a semi-round groove respectively; and the flat square hole is matched with the crankshaft flat square of the CA400 engine.

Description

Adopt the direct drive rotor engine oil pump of the flat side of engine crankshaft
Technical field
The utility model relates to a kind of rotor engine oil pump, and particularly a kind of is the supporting rotor engine oil pump of CA400 h type engine h.
Background technique
The CA400 h type engine h is the product that a kind of main frame unit newly researches and develops design, and it needs oil pump supporting with it, and require oil pump be motor under various operating conditions, provide that oil pressure is stable, flow abundant, the lubricating oil of reliable working performance.Existing oil pump mostly is to carry out transmission by modes such as gear, chain, cingulums, because the component of transmission system are more, increased this partly consumption of component material, and manufacturing man-hour and cost of production, the risk that this part part has an accident because of damage also increased simultaneously.In addition, these component have increased the weight of engine dry weight, have increased the loss of motor self power, and the engine energy-saving consumption reduction is brought serious unfavorable factor.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and provide a kind of CA400 of aiming at h type engine h the supporting direct drive rotor engine oil pump of the flat side of employing engine crankshaft.
The technical solution of the utility model is: the direct drive rotor engine oil pump of the flat side of a kind of employing engine crankshaft, it is made up of the pump housing, pump cover, internal rotor, external rotor.External rotor is located in the rotor hole of the pump housing, and the rotor hole of the external rotor and the pump housing adopts movingly.Internal rotor is located in the die cavity of external rotor, and the die cavity of internal rotor and external rotor adopts movingly.Pump cover is installed in by screw on the pump housing at inner and outer rotors position, and pump cover will guarantee that rotor rotation is flexible after installing.The axis hole of internal rotor is a flat square hole, is respectively equipped with a semicircular groove on two straight flanges of flat square hole, and the bent axle of flat square hole and CA400 h type engine h flat side cooperate.
The direct drive rotor engine oil pump of the flat side of employing engine crankshaft that the utility model provides is installed in CA400 h type engine h body front end, flat square hole 3-1 on flat side of the bent axle of CA400 h type engine h and the rotor engine oil pump external rotor 3 cooperates, and directly drives rotor engine oil pump work by the bent axle of CA400 h type engine h.
The utility model compared with prior art has following characteristics:
1, the direct drive rotor engine oil pump of the flat side of employing engine crankshaft that provides of the utility model is custom-designed according to the supporting requirement of CA400 h type engine h lubrication system, can guarantee into the CA400 h type engine h under various operating conditions, provide that oil pressure is stable, flow abundant, the lubricating oil of reliable working performance.
2, the direct drive rotor engine oil pump of the flat side of employing engine crankshaft that provides of the utility model has been saved the corresponding part of transmission system owing to adopt the direct kind of drive of bent axle.Therefore, it is simple in structure, novel in design, easy for installation, has improved stability, reliability, Security and the working life of oil pump work.Simultaneously, save steel, alleviated the in-fighting of own wt and engine power, and reduced the cost of production of manufacturing aspect.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
