Abstract
The utility model relates to a plate spring supporting type spin-on filter. The plate spring supporting type spin-on filter comprises a shell and a filter element assembly installed in the shell and used for filtering machine oil, and a supporting plate spring for preventing the filter element assembly from waggling in the shell is arranged between the lower end face of the filter element assembly and the bottom of the shell. Compared with the prior art, the rolling-up angle of the tail ends of supporting legs can be adjusted according to needs, and therefore bearing reaction of the supporting plate spring can be adjusted, the supporting plate spring can flexibly adapt to filters in different sizes, mold cost is saved, and management cost of stored materials is reduced; not only is the axial position of the filter element assembly fixed through the bearing reaction of the supporting plate spring, but also the filter element assembly is connected with a corner in the shell of the filter through the supporting legs in a matched mode, the radial position of the filter element assembly in the shell is fixed, the fixing effect is obviously superior to a spring type supporting plate, and the stability and the reliability of the filter are improved.
Description
Technical field
The utility model relates to filter cleaner technical field, especially relates to a kind of supported by plate spring formula rotary filter.
Background technique
Oil filter is the filtration of burden lubrication system medium.In engine working process, carbon distribution and gelatinous precipitate, water etc. oxidized under metal filings, dust, high temperature are constantly sneaked into lubricant oil.Oil filter is arranged in engine lubrication system, its upstream is oil pump, downstream is in motor, to need each component of lubricating, its effect is mechanical admixture and the colloid filtering out in machine oil, keep the clean of lubricant oil, the use that extends these component, it is strong that oil filter should have filtering ability, the performances such as circulating resistance is little, long service life.
As shown in Figure 1, at present, supporting structure between the lower end surface of the filter core assembly 2 of conventional rotary mounting engine oil filter and housing 1 bottom adopts the supported spring 3 of form of springs, spring is as a kind of working standard part, can facilitate as requested and regulate compress variation, but for the filter cleaner of different size, the size of supported spring 3 need to redesign checking, this has just caused component different state in the filter cleaner of different model, is unfavorable for standardized designs, production mistake proofing and stock control etc.And, in assembly, playing fixed support and do the used time, supported spring 3 only has axial action, and radial direction does not have fixation, easily causes filter core radially to rock and skewness in filter case.In addition, prior art does not have special processing for supported spring 3 and filter case 1 contact position, bottom, easily skids, and causes fixed position inequality.
Model utility content
The purpose of this utility model is exactly to provide a kind of supported by plate spring formula rotary filter in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions: a kind of supported by plate spring formula rotary filter, comprise housing and be arranged on the filter core assembly of the filtration machine oil in housing, it is characterized in that, between the lower end surface of described filter core assembly and housing bottom, be provided with the support leaf spring that restriction filter core assembly rocks in housing.
Described support leaf spring comprises the support mainboard for supporting filter core assembly, this support main plate center is provided with opening, supports on mainboard and is connected with leg, and this leg is fixed in housing, described leg arranges with supporting mainboard bending, makes to support upwards projection of leaf spring.
Described leg end scrolls up, and leg is fixed by the corner laminating of rolling in position and housing, plays the radial location effect to filter core assembly.The angle of rolling by adjusting leg end, can change the support reaction (pretightening force) that supports leaf spring, makes to support leaf spring and can be applicable to flexibly the filter cleaner of different size.
Described support mainboard both sides are connected with respectively two legs, between two legs, leave gap.
Compared with prior art, the utlity model has following advantage:
1, the standardization of products: can adjust as required the angle that leg end is rolled, and then adjust and support the support reaction of leaf spring, make to support leaf spring and can be applicable to flexibly the filter cleaner of different size, save die cost, reduce storage material administration cost;
2, reliability is high: the axial position of not only fixing filter core assembly by supporting the support reaction of leaf spring, also be connected by the corner in leg and filter case, fix the radial position of filter core assembly in housing, fixed effect is obviously better than form of springs dunnage, has improved stability and the reliability of filter cleaner.
Accompanying drawing explanation
Fig. 1 is the part-structure schematic diagram of prior art medi-spring supporting type rotary filter;
Fig. 2 is part-structure schematic diagram of the present utility model;
Fig. 3 is the structural representation that the utility model supports leaf spring.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 2, a kind of supported by plate spring formula rotary filter, comprise housing 1 and be arranged on the filter core assembly 2 of the filtration machine oil in housing 1, the lower end surface of described filter core assembly 2 is provided with lower end cap 21, is provided with the support leaf spring 3 that restriction filter core assembly 2 rocks in housing 1 between the lower end surface of described lower end cap 21 and housing 1 bottom.
As shown in Figure 3, described support leaf spring 3 comprises the support mainboard 31 for supporting filter core assembly 2, these support mainboard 31 centers are provided with opening 32, the both sides of supporting mainboard 31 are connected with respectively two legs 33, between two legs 33, leave gap, leg 33 arranges with supporting mainboard 31 bendings, makes to support leaf spring 3 to upper process.Described leg 33 ends scroll up, and leg 33 is fixed by the corner laminating of rolling in position and housing 1, plays the radial location effect to filter core assembly 2.The angle of rolling by adjusting leg 33 ends, can change the support reaction that supports leaf spring 3, makes to support leaf spring 3 and can be applicable to flexibly the filter cleaner of different size.
