Abstract
The utility model provides a rotor engine oil pump adopting a crank shaft for direct transmission, which is matched with YC4W75-30 type diesel engines. The rotor engine oil pump consists of a pump body, a pump cover, an inner rotor and an outer rotor, wherein the outer rotor is arranged in a rotor hole of the pump body, the inner rotor is arranged in a die cavity of the outer rotor, and the pump cover is covered on the rotor hole of the pump body and is arranged on the pump body through screws. After the pump cover is arranged on the pump body, the outer rotor arranged in the rotor hole of the pump body and the inner rotor arranged in the die cavity of the outer rotor have flexible rotation. A shaft hole of the inner rotor is designed into a flat square hole, a groove is respectively arranged on two straight edges of the flat square hole, and the flat square hole is matched with a crank shaft of the YC4W75-30 type diesel engine in a flat square mode. Small oil spray holes are arranged on an oil passage of a case of the pump body, and oil is sprayed on other parts through the small oil spray holes for lubrication.
Description
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 YC4W75-30 type diesel engine.
Background technique
For the supporting YC4W75-30 type diesel engine of car, need structure advanced person's new oil pump supporting, so that further improve the usability of motor.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 for the supporting direct drive rotor engine oil pump of employing bent axle of YC4W75-30 type diesel engine.
The technical solution of the utility model is: a kind of rotor engine oil pump, it is made up of the pump housing, pump cover, internal rotor and external rotor.External rotor is installed in the rotor hole of the pump housing, and internal rotor is installed in the die cavity of external rotor, and pump cover covers on the rotor hole of the pump housing, and is installed on the pump housing by screw.After pump cover is installed on the pump housing, is installed in the external rotor in the pump housing rotor hole and is installed in the interior internal rotor rotation of external rotor die cavity and want flexibly.The axis hole of internal rotor is designed to flat square hole, is respectively equipped with a groove on two straight flanges of flat square hole, and the bent axle of flat square hole and YC4W75-30 h type engine h flat side cooperate.
The oil duct of the rotor engine oil pump pump housing housing that the utility model provides is provided with little nozzle opening, by little nozzle opening other component is carried out oil jet lubrication.
The direct drive rotor engine oil pump of the flat side of employing engine crankshaft that the utility model provides is installed in YC4W75-30 h type engine h body front end, flat square hole on flat side of the bent axle of YC4W75-30 h type engine h and the rotor engine oil pump external rotor cooperates, and directly drives rotor engine oil pump work by the bent axle of YC4W75-30 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 YC4W75-30 h type engine h lubrication system, can guarantee into the YC4W75-30 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 rotor engine oil pump 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.
