Abstract

The utility model provides an oil cleaner is inhaled to gearbox, which comprises an upper housing, lower casing, an upper housing, lower casing is round rectangle's framework and specification the same, it is vertical to the screw thread counter bore that runs through an upper housing to go up casing circumference to be equipped with a plurality of edges, the casing corresponds every screw thread counter bore department down and all is equipped with screw thread counter bore assorted screw hole, the framework middle part of casing is equipped with latticed strengthening rib down, an upper casing, press from both sides the upper filter screen that is equipped with upper and lower superpose between the casing down, lower floor's filter screen, an upper filter screen, lower floor's filter screen is stainless steel wire cloth, and lower floor's filter screen aperture is 90 meshes, upper filter screen aperture is 180 meshes, upper filter screen, correspond every screw thread counter bore department on lower floor's filter screen position and all be equipped with screw thread counter bore assorted through-hole. On the basis of meeting the filtering index, the filter realizes the reduction of the resistance performance of the oil suction filter, and meanwhile, the filter element adopts two-stage filtering, and has the characteristics of high filtering performance, long service life and the like.

Description

Oil filter is inhaled to gearbox

Technical Field

The utility model relates to an oil cleaner is inhaled to gearbox.

Background

At present, for the oil suction filter of the gearbox, the performance indexes of the oil suction filter of the gearbox mainly include the filtering performance and the resistance of the filter under the specified flow rate, and the existing oil suction filter of the gearbox has the problem that the thickness of the filter needs to be increased or the mesh number of filtering materials needs to be increased in order to achieve the sufficient filtering effect, so that the defect that the resistance value of the filter under the target flow rate is overlarge, namely the resistance value exceeds 27.5kPa when the flow rate is 40L/min, and the good operation of the gearbox cannot be ensured.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that an oil cleaner is inhaled to gearbox is provided, it has reduced the resistance when the filter effect satisfies the demands.

In order to solve the technical problem, the utility model provides a gearbox oil absorption filter, which comprises an upper shell and a lower shell, wherein the upper shell and the lower shell are all frame bodies with round-angle rectangles and have the same specification, the upper shell is circumferentially provided with a plurality of thread counter bores vertically penetrating through the upper shell, the lower shell is provided with thread holes matched with the thread counter bores corresponding to each thread counter bore, the middle part of the frame body of the lower shell is provided with latticed reinforcing ribs, an upper layer filter screen and a lower layer filter screen which are overlapped up and down are clamped between the upper shell and the lower shell, the upper layer filter screen and the lower layer filter screen are both stainless steel wire cloth, and the aperture of the lower layer filter screen is 90 meshes, the aperture of the upper layer filter screen is 180 meshes, through holes matched with the thread counter bores are arranged at the positions of the upper layer filter screen and the lower layer filter screen corresponding to each thread counter bore, and the upper shell and the lower shell are connected through bolts matched with the thread counter bores.

For the sake of simple explanation, the following is the present filter for the transmission oil suction filter of the present invention.

The use method of the filter comprises the following steps: in the filter settling tank of arranging the gearbox in when this filter uses, gearbox oil is through lower casing earlier through this filter's order, then through lower floor's filter screen, upper filter screen, last through last casing.

The filter has the advantages that the lower shell is provided with the reinforcing ribs, the upper shell is not provided with the reinforcing ribs, the double-layer filter screen is adopted, the resistance value is 6.1kPa when the flow is 40L/min, and the resistance value is far lower than the design requirement of the gearbox, the filter realizes the reduction of the resistance performance of the oil suction filter on the basis of meeting the filtering index, and meanwhile, the filter element adopts two-stage filtering, so that the filter has the characteristics of high filtering performance, long service life and the like.

Detailed Description

Referring to fig. 1, a gearbox oil absorption filter comprises an upper shell 1 and a lower shell 2, wherein the upper shell 1 and the lower shell 2 are round rectangular frames and have the same specification, a plurality of thread counter bores 11 vertically penetrating through the upper shell 1 are arranged in the circumferential direction of the upper shell 1, thread holes 21 matched with the thread counter bores 11 are arranged at positions, corresponding to the thread counter bores 11, of the lower shell 2, latticed reinforcing ribs 22 are arranged in the middle of the frame of the lower shell 2, an upper-layer filter screen 3 and a lower-layer filter screen 4 which are vertically overlapped are clamped between the upper shell 1 and the lower shell 2, the upper-layer filter screen 3 and the lower-layer filter screen 4 are both made of stainless steel wire cloth, the aperture of the lower-layer filter screen 4 is 90 meshes, the aperture of the upper-layer filter screen 3 is 180 meshes, through holes 5 matched with the thread counter bores 11 are arranged at positions, corresponding to the thread counter bores 11, of the upper-layer filter screen 3 and the lower-layer, The lower case 2 is attached.

The use method of the filter comprises the following steps: in the filter settling tank of arranging the gearbox in when this filter uses, gearbox oil is through lower casing 2 earlier through the order of this filter, then through lower floor's filter screen 4, upper filter screen 3, at last through last casing 1.

The filter has the advantages that the lower shell 2 is provided with the reinforcing ribs 22, the upper shell 1 is not provided with the reinforcing ribs 22, and the double-layer filter screen is adopted, so that the resistance value is 6.1kPa when the flow is 40L/min, and the resistance value is far lower than the design requirement of a gearbox, the filter realizes the reduction of the resistance performance of the oil suction filter on the basis of meeting the filter index, and meanwhile, the filter element adopts two-stage filtration, and has the characteristics of high filtration performance, long service life and the like.

The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
