Problems solved by technology

In this case, in addition to increasing manufacturing costs, there are problems in inventory management such as inventory adjustment due to deviations in the delivery status of various types of components
Also, since the filter elements have to be sorted and stored in part numbers of different sizes, there is a problem that the space efficiency of the storage room is reduced, and the storage space of the storage room for various element sizes must be changed, thereby causing a reduction in storage efficiency, The problem of high storage costs

Embodiment 1

[0016] Embodiment 1 (with reference to Figure 1-3 )

[0017] exist figure 1 and 2 Among them, the oil filter of Example 1 was constructed as follows. The housing 14 is formed, and the metal cylindrical container 11 is provided with an oil inflow port 12 on the side wall and an oil outflow port 13 in the bottom wall. A filter element 15 made of cellulose fibers, glass fibers or the like is accommodated in the housing 14 as a filter element. The filter element 15 is arranged such that its outer peripheral surface is on the oil inflow side and its inner peripheral surface is on the oil outflow side. The oil filtered and purified by the filter element 15 is discharged through the oil outlet 13 provided at the bottom of the casing 14 and returned to the oil sump. Such as figure 1 As shown, the element 15 is configured to cover the oil outlet 13 .

[0018] In addition, although the shape of this element 15 is cylindrical and cylindrical in illustration, it is not limited to ...

Embodiment 2

[0036] Embodiment 2 (with reference to Figure 5 ,Figure 6)

[0037] In Example 2, the same parts as those in Example 1 are denoted by the same symbols, and repeated description thereof will be omitted.

[0038] In Embodiment 1, the effective height dimension H of the filter element 15 can be adjusted to an integer multiple of the height dimension h of the element block 19 . In the case where it is necessary to further expand the range of size adjustment according to the flow rate of oil, Embodiment 2 is suitable.

[0039] In Example 2, such as Figure 5 As shown, the filter element 15 is formed by combining two types of element blocks 19A and 19B having different height dimensions ( h1 , h2 ) in an appropriate number (one each in the drawing). Among them, element block 19A is a small block, and 19B is a large block longer than 19A.

[0040] In this case, as shown in FIGS. 6A-6E , filter elements of various sizes can be configured using only two types of element blocks 19A...

Abstract

The prevent invention provides an oil filter comprising a filter element housed in a casing, the filter element being formed of two or more cylindrical element pieces piled on top of another in the height direction and attachably and detachably connected through connecting members. Accordingly, the efficiency in each of manufacture, stock control and storage of the filter element can be improved, and the cost can be also reduced.

Description

technical field [0001] The invention relates to an oil filter arranged on a hydraulic circuit of a construction machine and an assembly method thereof. Background technique [0002] An oil filter is provided on a return circuit for returning the driving hydraulic oil of a hydraulic actuator such as a hydraulic excavator to the oil tank, thereby removing dust from the hydraulic oil and purifying the hydraulic oil. The flow rate of oil in the hydraulic circuit changes according to the size of the excavator, and filter elements of various sizes having different filtering areas are required according to the flow rate. [0003] Therefore, the manufacturer must manufacture various types of components, and both the manufacturer and the user must stock the various types of components for exchange. In this case, in addition to increasing the manufacturing cost, there is also a problem in inventory management such as inventory adjustment due to deviations in the delivery status of va...
