Abstract
The utility model discloses an oil pump structure of a diesel engine. The oil pump structure provided by the utility model comprises an oil pump, a timing gear chamber and a crank chamber, wherein the oil pump comprises an oil pump shell and two gears which are arranged in the oil pump shell and meshed; one side of the oil pump shell is provided with an opening, the crank chamber is provided with a groove, and the oil pump shell is positioned in the groove arranged in the crank chamber; and the timing gear chamber covers the opening of the oil pump shell and the groove of the crank chamber, and the oil pump shell is mutually fixed with the timing gear chamber. According to the utility model, a front end cover of an integral oil pump is omitted, the timing gear chamber is utilized as the front end cover of the oil pump, and the oil pump is positioned in the groove on the crank chamber; the oil pump is firm in installation, when the oil pump is installed, the timing gear chamber and the oil pump shell are installed into a whole, then the timing gear chamber and the crank chamber are installed together, the structure is simplified, the installation is convenient, and the reliability is strengthened; and the reliability of the oil pump is improved, thereby avoiding the phenomenon that an engine can not be lubricated because the oil pump drops, so that the part is worn and even damaged.
Description
Technical field
The utility model relates to a kind of engine oil pump of internal combustion engine, relates in particular to a kind of diesel engine lubricating oil pump structure.
Background technique
Machine oil lubricate in the diesel engine oil pan, the function of lubrication system is anti-attrition, flushing, cooling and antirust.And oil pump has the function that is delivered to the machine oil in the oil sump whole lubricating system.Therefore the reliability of oil pump is related to the life-span of whole motor.In the existing technology, the oil pump of diesel engine adopts independent integrated type, is installed in the crankcase front end, complex structure, Heavy Weight, manufacture cost height.
Summary of the invention
The technical problem that the utility model will solve is: a kind of firm diesel engine lubricating oil pump structure of installing is provided.
In order to solve the problems of the technologies described above; The utility model comprises oil pump, housing for timing gear and crankcase, and described oil pump comprises oil pump housing and two gears that are meshed that are installed in the oil pump housing, and a side of oil pump housing is uncovered; Crankcase is provided with a groove; The oil pump housing is in the groove in the crankcase, and timing-gear chamber cover is on the groove of the uncovered and crankcase of oil pump housing, and oil pump housing and housing for timing gear fix.
For easy for installation; One end of the gear shaft of a gear in described two gears is arranged on the oil pump housing, the other end is arranged on the housing for timing gear; The gear shaft of another gear is the oil pump live axle; One end of oil pump live axle is arranged on the oil pump housing, the other end stretches out outside the housing for timing gear, and the oil pump live axle stretches out on the end outside the housing for timing gear and is connected with Oil pump drive gear.
In order to improve intensity, described crankcase is the integrated type foundry goods.
The beneficial effect of the utility model: the utility model has been cancelled the front cover of integral-type oil pump, but the front cover of housing for timing gear as oil pump, oil pump is in the groove on the crankcase; It is firm that oil pump is installed, and, when mounted; After housing for timing gear and oil pump housing were mounted to one, housing for timing gear was installed to crankcase again, makes to simplify the structure; Easy for installation, reliability is strengthened.Improved the reliability of oil pump, prevented to cause the phenomenon of component wear even damage because oil pump comes off and causes motor to lubricate.
