Description

A kind of oil filter

Technical field

The utility model belongs to technical field of engines, relates to a kind of oil filter.

Background technique

Motor main working parts such as bent axle, camshaft, rocking arm, piston ring and each bearing etc. is made with iron-bearing materials more than 90%.During engine operation, these moving elements inevitably have wearing and tearing, and the metal fragment that wearing and tearing produce, along with oil circulation, causes continual wearing and tearing to motor, has a strong impact on the working life of engine component.

In engine working process, carbon distribution and gelatinous precipitate, water etc. oxidized under metal filings, dust, high temperature are constantly sneaked into lubricant oil.The effect of oil filter is exactly to filter these mechanical admixtures and colloid, protects the cleaning for the treatment of lubricant oil, extends its life time.Oil filter should have that the filtering ability is strong, and circulating resistance is little, the performances such as long service life.In general lubricating system dress is with filter cleaner---fuel filter, strainer and the fine cleaner of several different filtering abilities, respectively parallel connection or be connected in main oil gallery.Wherein strainer one is connected in main oil gallery, is full flow type; Fine cleaner is connected in parallel in main oil gallery, is flow deviding type.Generally only be provided with fuel filter and a full-flow oil filter on modern car engine.In strainer filtering machine oil, particle diameter is the above impurity of 0.05mm, and it is the above fine impurities of 0.001mm that fine cleaner is used for the filtering particle diameter.

Disclosing a kind of Magnetizing devcie for oil filter in patent [03256048.6], is a kind of magnetizing assembly of the oil filter for various motors.This device is half annulated column that matches with housing of oil filter, is embedded with a watt shape magnet on the inwall of half annulated column, is glued with steel plate on the cylinder of magnet evagination, and the skin of steel plate has corrosion resistant plate, by rivet, with half annulated column, is connected.This device does not take the inner original design space of oil filter, so oil filter is difficult for stopping up, and is easy for installation, relies on the shell that self magnetic is inhaled in oil filter to get final product, and do not have External Force Acting not come off.Magnetic is strong, can effectively adsorb micron-sized metallic dust, guarantee the turbidity test degree of machine oil, this device can be made into different size with applicable various engine oil filters, reusable, to reduce expenses, still, watt shape magnet in this oil filter blocks the machine oil intake section, affected passing through of machine oil, and after iron adsorption is more, entrance will be less, and will be unfavorable to the circulation of machine oil.

Summary of the invention

The purpose of this utility model is the problems referred to above that exist for existing technology, and a kind of oil filter is provided, and technical problem to be solved in the utility model is the iron filings of how effectively eliminating in machine oil.

The purpose of this utility model can realize by following technical proposal: a kind of oil filter, comprise skeleton, be wrapped in the filter paper on skeleton, it is characterized in that, the two ends of described skeleton are fixedly installed respectively a upper end cap and lower end cap, offer a machine oil entrance on described upper end cap, also be fixed with an adsorption bar of being made by magnetic material in described skeleton, the cross section of described adsorption bar is rounded; The diameter of described adsorption bar is dwindled to two ends gradually by middle part; Described adsorption bar be positioned at the machine oil entrance under.

Working principle of the present utility model is: when machine oil enters the machine oil entrance from oil sump, wash away adsorption bar, adsorption bar is that magnet is made, and adsorption bar can prevent that iron filings from entering with machine oil in the friction pair of motor with the iron adsorption in machine oil, forms the secondary wearing and tearing; Due to absorption be positioned at the machine oil entrance under, and the two ends of this adsorption bar are less, can not stop up the machine oil entrance, adsorption bar small in ends, broad in the middle forms a smooth curved surface, is conducive to flowing through of machine oil.

In above-mentioned a kind of oil filter, be fixedly installed a support on described skeleton, described support also is connected with described adsorption bar.Adsorption bar is fixed in framework inner cavity by support, and its magnetic field is subject to weakening and the barrier of metal skeleton, can not disturb in-engine electronic unit.

In above-mentioned a kind of oil filter, the middle part of described adsorption bar has a mounting groove, and described support comprises inner ring and outer ring, is connected by spoke between described inner ring and outer ring, and described inner ring is connected in described mounting groove.Between inner ring and outer ring by having larger space, so that the passing through of machine oil.

In above-mentioned a kind of oil filter, described inner ring is that plastic material is made, and described outer ring is that metal material is made, and described outer ring is welded on described skeleton.Before installing end cap and lower end cap, this support welding on skeleton,, owing to having through hole on skeleton, be need not during welding welding rod is stretched into framework inner cavity, directly can complete and be welded and fixed outside skeleton.

In above-mentioned a kind of oil filter, described spoke has three, and is evenly distributed between inner ring and outer ring.The setting of spoke radical needs to consider the constant intensity of adsorption bar and mobile smooth and easy two factors of machine oil that in this programme, spoke is set to three.

Compared with prior art, the utlity model has following advantage:

1, be provided with adsorption bar in this oil filter, when machine oil enters the machine oil entrance from oil sump, wash away adsorption bar, adsorption bar is that magnet is made, adsorption bar can prevent that iron filings from entering with machine oil in the friction pair of motor with the iron adsorption in machine oil, forms the secondary wearing and tearing.

2, due to absorption be positioned at the machine oil entrance under, and the two ends of this adsorption bar are less, can not stop up the machine oil entrance, adsorption bar small in ends, broad in the middle forms a smooth curved surface, is conducive to flowing through of machine oil.
