Description
Technical field:
The utility model lower case of engine body oil pump base housing structure relates to the field of the lower case of engine body oil pump base housing structure that the engine oil pump assembly is installed.
Background technique:
Because the component Sliding velocity of motion is very big mutually in motor, the load that the component surface of phase mutual friction bears is just bigger, in order to guarantee that each component of engine interior obtain lubricated reliably and strong cooling, then will the fitting machine oil pump in the lower case of engine body, machine oil is applied forced draught, and it is lubricated to make the component that turn round in the motor obtain fuel feeding.
When motor turns round under various operating modes, bent axle rotates in spindle hole, drive the rotation of oil pump assembly simultaneously, the oil pump assembly is drawn into the machine oil in the casing in the lower box oil pump base housing from the oil pump import, after making low-pressure oil be transformed into high-pressure oil, pump into again in the oil pump output main oil gallery, thereby guarantee to have good lubricating between each kinematic pair of motor, reduce the friction and wear between each kinematic pair, make motor be in normal operating condition.
In order to guarantee that above motor inner engine oil lubricates and the normal operation of refrigerating function, then should design the simple compact lower case of engine body oil pump base housing structure of desired structure.
Summary of the invention:
The purpose of this utility model provides a kind of lower case of engine body oil pump base housing structure, the designed oil pump assembly of this lower case of engine body oil pump base housing by installing on its oil pump base main casing in the lower case of engine body can be pumped into the machine oil in the lower box between each kinematic pair of motor by the oil pump filler opening and be lubricated.
Lower case of engine body oil pump base housing structure, it is made up of oil pump base main casing, low-pressure tank, high pressure oil groove, oil pump assembly mounting hole, filter screen draw-in groove, oil pump filler opening, oil pump output main oil gallery and lower box, oil pump base main casing evagination is in the lower box bottommost, and constitute one with lower box, on oil pump base main casing sidewall, have oil pump filler opening and oil pump output main oil gallery, the oil pump assembly mounting hole and the filter screen draw-in groove that outwards link to each other and extend are arranged on oil pump base main casing sidewall; Have low-pressure tank, high pressure oil groove and oil pump assembly spindle hole at oil pump base main casing inner bottom part; On the lower box sidewall, have the oil discharge screw hole.
The structure design principle of the utility model lower case of engine body oil pump base housing is as follows:
1, on oil pump base main casing, has oil pump assembly mounting hole, for fastening oil pump assembly is installed.
2, the bottom in oil pump base main casing has low-pressure tank and high pressure oil groove, for storing low-pressure oil and high-pressure oil, uses for low-pressure oil and high-pressure oil conversion circulation.
3, have oil pump assembly spindle hole in oil pump base main casing centre bottom, for fitting machine oil pump assembly main shaft.
4, on oil pump base main casing, have oil pump filler opening and oil pump output main oil gallery, enter with high pressure oil for low pressure oil and export.
5, on the oil pump base main casing outside the oil pump filler opening of oil pump base main casing, have the filter screen draw-in groove, for the fitting machine oil screen, machine oil is carried out first filter cleaning, and the lubricating oil of box house enters the oil pump filler opening after filtering in the filter screen earlier again.
Oil pump base main casing is a cylindrical housings, be positioned at the lower box bottommost, and be in the next door in the engine spindle hole that engine crankshaft is installed, oil pump base main casing and lower box be Cheng Mo once, be in lower box, to be used for the parts of fitting machine oil pump assembly,, use by pump oil with the oil pump assembly for engine lubrication.
The oil pump filler opening is opened on the circular cylindrical shell body sidewall of oil pump base main casing, is positioned at the bottommost of lower box, is connected with oil pump base main casing inside, enters in the oil pump base main casing for machine oil, and the oil pump filler opening is a circular hole; On the sidewall of lower box, have the oil discharge screw hole, open oil discharge screw, then can in the oil discharge screw hole, discharge the lower box inner engine oil, in order to make the shared frock clamping of oil discharge screw hole and oil pump filler opening location man-hour adding, realize the aperture of the different sizes of processing, during design, the medial axis in oil discharge screw hole of circle hole shape and the medial axis of oil pump filler opening are on same the central axis.
In sum, timing gear on the bent axle of installing in the engine spindle hole drive the work of oil pump assembly, oil pump pumps into the lubricating oil of lower box inside in the oil pump base main casing from the oil pump filler opening, after making the interior low-pressure oil of lower box transform into high-pressure oil through oil pump, be pumped into oil pump output main oil gallery again, enter into the motor whole lubricating system then, for lubricating between each kinematic pair of motor.
The utility model lower case of engine body oil pump base housing and lower box are designed to one, and its advantage is to save the space, simplifies the blank processing technology, makes engine structure compacter, simple.
When such motor is installed on the lawn mower, when working,, just can guarantee that motor constantly supplies with machine oil because the oil pump filler opening is positioned at the lower box lowest part at bad landform places such as rough lawn or Gao Po, and fuel feeding is even, makes to start the function proper functioning.Because the oil discharge screw hole of oil pump filler opening and lower box is positioned on same the central axis, the location processing of available anchor clamps cuts down finished cost.
