The utility model solves the technical problems that the rotary speed of the existing casting filter is low, and final assembly cleanliness is not easy to control. A rotor shaft of the centrifugal engine oil filter of the utility model is screwed on a base, a rotor block mechanism which is in sleeve joint on the rotor shaft can freely rotate, a housing is sheathed on the outside of the rotor block, the top of the housing is fixed on the rotor shaft through a screw cap and the bottom of the housing is hermetically connected with the base. The rotor block mechanism is composed of an upper bearing, a lower bearing, a soleplate, an inner baffler, a diversion pipe and a rotor cover, wherein the diversion pipe is arranged on a central axial position of the rotor cover; the upper and the lower bearings are fixed on an upper and a lower ends of the diversion pipe; a position near the upper part of the soleplate is provided with the inner baffler which is inclined towards the soleplate; the top of the rotor cover is provided with a circular arc-shaped groove which extends along the rotary direction of the rotor block. The connection mode of the rotor cover, the soleplate and the inner baffler is a spin-on type filtering sealing, wherein the rotor cover, the soleplate and the inner baffler are all thin steel plate stampings and the upper and the lower bearings are both metallurgical extrusions of tin and copper powder. The utility model is mainly used for a vehicle engine, and the engine oil of the engine is cleaned in order to better protect the engine.
Description
Technical field: the utility model relates to a kind of motor oil filter, particularly a kind of spin-on oil filter.
Background technique: spin-on oil filter commonly used at present generally is that cutting forms after adopting die casting, and operation is comparatively complicated, and assembling difficulty is big, and because filter core assembly is cast member, and heavier, rotating speed is lower, turbidity test are wayward.
Summary of the invention: the purpose of this utility model provides and a kind ofly assembles easily, weight is light, the higher spin-on oil filter of rotating speed.The technical solution of the utility model is: a kind of spin-on oil filter, constitute by base, shell, rotor shaft, rotor body mechanism, rotor shaft is twisted and is connected on the base, rotor body mechanism is socketed on the rotor shaft, and can freely rotate, shell is enclosed within outer its top of rotor body and fixes by nut and rotor shaft, and outer casing bottom and base are tightly connected.Rotor body mechanism is made up of upper and lower bearing, base plate, interior guide plate, honeycomb duct, rotor housing, honeycomb duct is arranged on the center axial position of rotor housing, it is fixed with upper and lower bearing in two ends up and down, above close base plate, be provided with the interior guide plate that tilts to base plate, be provided with the circular groove that extends along the rotor body sense of rotation at the top of rotor housing, the Placement of rotor housing, base plate, interior guide plate is that the spinning filter is sealed, wherein rotor housing, base plate, interior guide plate are the sheet metal stamping part, and metal (upper is tin copper powder metallurgy extrusion.The beneficial effects of the utility model are: because the main member of rotor body mechanism is that sheet metal is stamped to form, do not need cutting, its weight is lighter, simple and compact for structure, metal (upper is tin copper powder metallurgy extrusion, makes that the turbidity test of whole general assembly are more easy to control, because the weight saving of rotor body, make motor when the driving rotor begins to rotate, guarantee the steady of rotating speed comparatively easily and easily, rotor unexpected stuck phenomenon in rotary course can not occur.When the rotor body rotating speed raises and is in the high speed rotating state, resistance of air square that it bore and machine oil resisting moment that impurity forms all sharply rise, in order to reduce the influence of these resisting moment, be provided with several circular grooves that extend along the rotor body sense of rotation at the top of rotor housing.The utility model is compared with existing casting and through the spin-on filter that cutting forms; under equal engine operation environment, can reach higher rotational speed; and rotating speed is steady, thereby the filter efficiency that has improved filter cleaner has been protected motor better.And the replacing of filter cleaner is simple and efficient when engine maintaining, and the general-utility car maintenance man all can operate.
Description of drawings:
Accompanying drawing is the utility model structural representation
Among the figure: 1-base, 2-rotor body mechanism, 2-1-lower bearing, guide plate in the 2-2-base plate, 2-3-, 2-4-honeycomb duct, 2-5-rotor housing, 2-6-upper bearing (metal), 3-rotor shaft, 4-shell.
Embodiment: with reference to accompanying drawing, a kind of spin-on oil filter, constitute by base 1, shell 4, rotor shaft 3, rotor body mechanism 2, rotor shaft 3 is twisted and is connected on the base 1, rotor body mechanism 2 is socketed on the rotor shaft 3, and can freely rotate, shell 4 is enclosed within outer its top of rotor body and fixes by nut and rotor shaft, and shell 4 bottoms and base 1 are tightly connected.Rotor body mechanism 2 is by last, lower bearing (2-6,2-1), base plate 2-2, interior guide plate 2-3, honeycomb duct 2-4, rotor housing 2-5 forms, honeycomb duct 2-4 is arranged on the center axial position of rotor housing 2-5, it is fixed with at two ends up and down, lower bearing (2-6,2-1), the assembling that is pressed into of metal (upper is finished by hydraulic machine, and guarantee its coaxality, above close base plate, be provided with the interior guide plate 2-3 that tilts to base plate, be provided with the circular groove that extends along the rotor body sense of rotation at the top of rotor housing, circular groove quantity is the 4-8 root, rotor housing, base plate, the Placement of interior guide plate is that the spinning filter is sealed, rotor housing wherein, base plate, interior guide plate is the sheet metal stamping part, and metal (upper is tin copper powder metallurgy extrusion.All belong to no cutting, make that whole assembly turbidity test are more easy to control.Must clean the requirement of satisfying turbidity test before all part assemblings.Working principle of the present utility model is: the trend of its oil circuit is with reference to the arrow in the accompanying drawing, the machine oil of motor flows into base 1 from oil inlet hole, and the oilhole on rotor shaft 3 sprays, enter rotor body mechanism 2 inner chambers along honeycomb duct 2-4 inwall, participate in the high speed rotating of rotor body mechanism 2, under the inertial centrifugal force effect that high speed rotating produced, contained granule foreign is deposited in rotor body mechanism 2 inwalls in the machine oil, and will spray rapidly along two nozzles of rotor body mechanism through the machine oil after the filtering, be injected in the reaction force continuation promotion rotor body mechanism of spraying by means of oil stream on the base and make high speed rotating, thereby reach the purpose of high efficiency impurity screening.When motor drives to certain fare register, the suitable quantity of impurity Ji Dian after the in-house filtration of rotor body, make the weight of rotor body mechanism increase, and oil flows the gravity that the upwards Driving force of spraying can not overcome integral body, and the filtration of filter cleaner will slowly be lost, and needing the filter core of replacing filter cleaner is rotor body mechanism, at this moment, the maintaining worker of motor only needs the shell nut of filter cleaner is backed out, and changes inner rotor body mechanism and body seal circle and gets final product, and easy maintenance is quick.
