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 invention relates to a gearbox oil suction filter.

Background

The gearbox oil suction filter plays a role in filtering gearbox oil and is generally horizontally arranged in the gearbox. At present, for a gearbox oil suction filter, performance indexes of the gearbox oil suction filter mainly include filtering performance and resistance of a filter under specified flow, and the existing gearbox oil suction filter has the problem that the thickness of the filter needs to be increased or the mesh number of a filtering material needs to be increased in order to achieve sufficient filtering effect, so that the defect that the resistance value of the filter under the target flow is too large, namely the resistance value exceeds 27.5kPa when the flow is 40L/min, and the gearbox cannot be guaranteed to run well is brought.

Disclosure of Invention

The invention aims to provide a gearbox oil suction filter which can reduce resistance while meeting the requirement of the filtering effect.

In order to solve the technical problem, the invention provides a gearbox oil absorption filter which comprises an upper shell and a lower shell, wherein the upper shell and the lower shell are both round rectangular frame bodies and have the same specification, a plurality of thread counter bores vertically penetrating through the upper shell are arranged on the periphery of the upper shell, a thread hole matched with the thread counter bore is formed in the position, corresponding to each thread counter bore, of the lower shell, latticed reinforcing ribs are arranged in the middle of the frame body of the lower shell, 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, 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 formed in the positions, corresponding to each thread counter bore, and bolts matched with the thread counter bores are used for connecting the upper shell.

For the sake of simplicity, the transmission oil filter according to the present invention is hereinafter referred to simply as the present filter.

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: this filter adopts the casing down to have the strengthening rib, go up the casing and do not have the strengthening rib, and adopts double-deck filter screen, and the experience is when flow 40L/min, and the resistance value is 6.1kPa, and the resistance value is far less than the design demand of gearbox, and this filter has realized reducing the oil absorption filter resistance performance on satisfying the basis of filtering the index, and the filter core adopts the two-stage to filter simultaneously, has characteristics such as filtering quality height, long service life.

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: this filter adopts casing 2 down to have strengthening rib 22, go up casing 1 and do not have strengthening rib 22, and adopt double-deck filter screen, and the experience is proved when flow 40L/min, and the resistance value is 6.1kPa, and the resistance value is far less than the design demand of gearbox, and this filter has realized reducing the oil absorption filter resistance performance on satisfying the basis of filtering the index, and the filter core adopts the two-stage filtration simultaneously, has characteristics such as filtration performance height, long service life.

The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
