Description
Technical field:
The utility model relates to the oil pump in each lubricated part that a kind of lubricant oil supplies to single cylinder or double-cylinder horizontal diesel.Belong to the diesel engine oil pump field.
Background technique:
Oil pump is arranged at the diesel engine casing outside usually, and its effect is lubricant oil to be pressed onto by each design oil duct need the fuel feeding position.For guaranteeing diesel engine work reliability, durability and its usage economy, many requirements have been proposed oil pump.
Summary of the invention:
The purpose of this utility model is to invent a kind of directly by the shaft-driven single-double-cylinder horizontal diesel machine-oil pump of diesel engine cam ring.
The purpose of this utility model be achieved in that single-double-cylinder horizontal diesel machine-oil pump by machine oil pump case, oil pump cover, internal rotor, external rotor, machine oil pump shaft, internal rotor bearing pin, import and export oil duct, connecting bolt and bolt hole and attachment face and seam thereof and form, it is characterized in that: this oil pump integral body is made up of two-part up and down, the lower end is machine oil pump case (1), external rotor (6) and internal rotor (5) are equipped with in machine oil pump case inside, and the machine oil pump shaft (4) of driving internal rotor rotation and the internal rotor bearing pin (3) of fixation machine oil pump shaft are arranged on the internal rotor (5); The upper end is oil pump cover (2), and two-part are connected by hexagon socket cap head screw (7) up and down.
Machine oil pump case (1) lower end surface is attachment face (11), seam (12), oil pump filler opening (13), oil outlet (14) are arranged on attachment face, also have oil pump construction bolt hole (81), oil inlet hole (15), oil outlet (16), oil pump axis hole (41), hexagon socket cap head screw hole (71) on the machine oil pump case, the upper-end surface of machine oil pump case is oil pump body cover attachment face (17).
Oil pump cover (2) lower end surface is oil pump body cover attachment face (17), on the lower end surface, also have oil input channel (21), oil road (22), join oil duct (23), on oil pump cover, also have hexagon socket cap head screw hole (71), oil pump axis hole (41) and oil pump construction bolt hole (81).
Working principle: internal rotor (5) and external rotor (6) rotation are arranged in the machine oil pump case (1), wherein internal rotor (5) is connected with Diesel Driven axle (camshaft) by machine oil pump shaft (4), on internal rotor (5) excircle external tooth is arranged, have on the circle in the external rotor (6) than internal rotor (5) and Duo the internal tooth of a tooth, it is inner eccentric also by the external tooth and the engagement of external rotor (6) internal tooth of internal rotor (5) with external rotor that external rotor (6) is placed in internal rotor (5) installation, produces the gap cavity volume of a tooth like this between internal rotor (5) and the external rotor (6).When machine oil pump shaft (4) rotates, external rotor (6) and internal rotor (5) are along with rotation, regular variation takes place in the volume of the chamber volume that is limited between the external tooth of the internal tooth of external rotor (6) and internal rotor (5), thereby lubricating oil is extruded or discharges from oil outlet (14), the lubricating oil of the other end is inhaled in the oil pump by filler opening (13), to guarantee the work of pump., by camshaft actuated the oil pump center line is arranged and the camshaft central lines for guaranteeing oil pump.
The utility model has the advantages that: this single-double-cylinder horizontal diesel oil pump is directly driven by engine cam, has reduced intermediate transmission mechanism, and the oil lubrication oil duct is arranged short, has reduced noise, compact structure, and the reliability height, easy for installation, high lubricating effect.
