Abstract
The utility model relates to a gearbox oil pan with a dual filtering function. A bracket is of a concave shape and connected with a filter net. The bracket is fixed on a shell through a bracket bolt. The bottom of the bracket is provided with an oil leakage hole. An annular magnet is arranged at the bottom of the bracket in an attracted mode. A press plate is provided with a circular hole. The bracket, the annular magnet and the press plate are connected and fixed to the bottom of the bracket through bolts and nuts. The oil leakage hole, a circular hole of the annular magnet and the circular hole in the press plate are communicated. An oil outlet of the oil pan is sealed through a screw plug and a spacer. The gearbox oil pan with the dual filtering function has the advantages that the filter net and the annular magnet jointly play a role in filtering a circulating oil circuit, so that the cleanness of liquid oil is improved, and the self-cleaning function of the liquid oil of a gearbox is greatly improved; furthermore, as the shell of the oil pan is machined and formed by the adoption of iron castings, strength is high compared with a stamping formed part; in addition, the installation matching surface of the oil pan and the gearbox is easy to install and seal, and the adaptability of the oil pan to domestic working conditions is high.
Description
Technical field
The utility model relates to a kind of filter oil drain pan that is installed on gearbox bottom.
Background technique
At present, oil sump is generally installed on gearbox bottom, be used for sealing gearbox and coordinate casing collect and storage gearbox in the pressure oil that flows back to of the lubricant oil that flows back to of each lubricated place and torque-converters, piston and valve.Oil sump housing is directly connected by attachment face and the gear box at top, and the general drawing of housing, by the preliminary filtering of filter screen, is provided with oil drain plug and oil outlet tube at housing bottom.The filtering weak effect of these oil sumps, can not filter well tiny iron filings, in oily cyclic process, may cause the obstruction of valve, and because housing adopts impact briquetting, for cast housing, intensity is lower, can not bear certain colliding with, have some limitations, low to engineering machinery bad working environments adaptability.
Summary of the invention
The purpose of this utility model is to provide a kind of gear box oil drain pan of simple in structure, double filtration that filtering is effective.
The purpose of this utility model is achieved in that bracket is spill, above bracket, be connected with filter screen, bracket bolt by bracket be fixed on housing above, oil leaking hole is arranged at the bottom of bracket, ring magnet is adsorbed on the bottom of bracket, has circular hole on pressing plate, and bracket, ring magnet and pressing plate are connected and be fixed on the bottom of bracket by bolts and nuts, oil leaking hole communicates with circular hole and three holes of the circular hole on pressing plate of ring magnet, the oil outlet of plug screw and gasket seal oil sump.
Because the utility model has adopted said structure, filter screen and magnet play the filtering function of circulating oil path jointly, have improved the turbidity test of fluid, and gearbox fluid self-purification function obtains very large reinforcement; Oil sump housing adopts ironcasting machine shaping, compares impact briquetting part intensity high, and is easy to install and sealing with the installation fitting surface of casing, and oil sump described above is high to domestic adaptability for working condition.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural drawing.
Fig. 2 is the A-A sectional view of Fig. 1.
1 housing, 2 filter screens, 3 bracket bolts, 4 plug screws, 5 pads, 6 brackets, 7 ring magnets, 8 pressing plates, 9 bolts, 10 packing rings, 11 nuts, 12 oil leaking holes in figure.
Embodiment
Embodiment: bracket 6 is spill, bracket 6 is connected with filter screen 2 above, bracket bolt 3 by bracket 6 be fixed on housing 1 above, oil leaking hole 12 is arranged at the bottom of bracket 6, ring magnet 6 is adsorbed on the bottom of bracket 6, on pressing plate 8, has circular hole, and bracket 6, ring magnet 7 and pressing plate 8 are connected and be fixed on the bottom of bracket 6 by bolt 9 and nut 11, oil leaking hole 12 communicates with the circular hole of ring magnet 7 and circular hole three holes on pressing plate 8, the oil outlet of plug screw 4 and pad 5 sealing oil sumps.
As shown in Figure 1 and Figure 2, the gear box oil drain pan of double filtration comprises housing 1, filter screen 2, bracket 6, ring magnet 7, pressing plate 8, oil leaking hole 12, two ring magnets 7 are adsorbed in respectively oil leaking hole 12 places of bracket 2 convex surface one sides, bracket 6 and corresponding processing bolt hole on pressing plate 8, pressing plate 8 is pushed down ring magnet 7 and is connected and fixed by bracket bolt 3, packing ring 10, nut 11; Filter screen 2 is placed in concave surface one side of bracket 6, and border is by being welded and fixed; Bracket 6, filter screen 2, ring magnet 7, pressing plate 8, bracket bolt 3, packing ring 10, the common filter assemblies that forms of nut 11; Housing 1 adopts Mechanical processing of casting to be shaped, and filter assemblies is mounted on housing 1 by bracket bolt 3, the oil outlet of plug screw 4 and pad 5 sealing oil sumps.
Oil sump is installed on gearbox bottom side, when falling into oil sump, first through filter screen 2, filters first fluid, through the fluid filtering, flow in housing 1, through the impurity filtering, be suspended on filter screen 2, under the suction-operated of ring magnet 7, can not move along with flowing of fluid, 7 pairs of ring magnets have suction-operated through the fine impurities in the fluid filtering first, and fluid is played to secondary filter effect, fluid is after secondary filter, by the oilhole participation systemic circulation of oil sump side.
Claims (1)
