Abstract
The utility model relates to a pump cover of an oil pump of an internal combustion engine, which forms a circular sheet shape. An oil inlet and an oil outlet are respectively arranged on the peripheral surface of the utility model, are respectively communicated with an oil inlet groove and an oil outlet groove which are arranged on a lateral surface of the utility model, and disassembly screw holes are arranged on the other lateral surface which is opposite to the oil inlet groove and the oil outlet groove. The utility model further provides an oil pump which is provided with a pump cover with the characteristics and is used for a lubrication system of an internal combustion engine. When the oil pump is required to be repaired, the pump cover can be conveniently disassembled to replace a pressure regulating gasket or a rotor. The utility model extends the service life of the oil pump and reduces manufacture cost and use cost.
Description
Technical field
The utility model relates to the oil pump of using in the lubricating system of IC engine, the pump cover on the particularly this oil pump.
Background technique
At present, the oil pump of using in the lubricating system of IC engine, contain the pump housing, internal rotor, external rotor, axle and pump cover, the pump housing is the overall structure that dish type is inner concavity, pump cover is fixed on the pump housing, be provided with the pressure regulation packing ring between the surface of contact of the pump cover and the pump housing, pump cover integral body is the disk shape, be respectively equipped with filler opening and oil outlet on its side face, filler opening and oil outlet respectively with a side on oil-feed tank and go out oil groove and interlink, with oil-feed tank with go out the relative another side of oil groove and be provided with mounting hole, the pump cover middle part matches with the axle activity, on the axle internal rotor is housed, internal rotor places in the external rotor, and external rotor places pump housing inner chamber.During use, the internal combustion engine drive axle rotates, axle drives internal rotor and external rotor rotates, volume between internal rotor and the external rotor flank profil is constantly changed, formation sucks lubricant oil from the inlet port of pump cover, after supercharging,, realize lubricating to the internal-combustion engine moving element from the oil outlet pressure oil output of pump cover.Deficiency: performance can not reach requirement and need reprocess after testing after oil pump assembling is finished, perhaps in use since the wearing and tearing of rotor cause performance can not reach requirement and need keep in repair, in the time of must changing the pressure regulation packing ring and regulate the rotor sideshake and require to reach design performance, pump cover can't be dismantled, can't keep in repair and scrap to the oil pump that allows to by the maintenance restorability, increase the manufacture cost and the user cost of oil pump.
Summary of the invention
The purpose of this utility model is to provide the pump cover of a kind of lubricating system of IC engine of convenient disassembly with oil pump.
Solution of the present utility model: integral body is the disk shape, be respectively equipped with filler opening and oil outlet on its side face, filler opening and oil outlet respectively with a side on oil-feed tank and go out oil groove and interlink, with oil-feed tank with go out the relative another side of oil groove and be provided with the dismounting screw.
The utility model further provides a kind of lubricating system of IC engine oil pump, contain the pump housing, internal rotor, external rotor, axle and pump cover, the pump housing is the overall structure that dish type is inner concavity, pump cover is fixed on the pump housing, be provided with the pressure regulation packing ring between the surface of contact of the pump cover and the pump housing, pump cover integral body is the disk shape, be respectively equipped with filler opening and oil outlet on its side face, filler opening and oil outlet respectively with pump cover one side on oil-feed tank and go out oil groove and interlink, with oil-feed tank with go out the relative another side of oil groove and be provided with the dismounting screw, the pump cover middle part matches with an axle activity, on the axle internal rotor is housed on the pump cover, internal rotor places in the external rotor, and external rotor places pump housing inner chamber.
After using the utility model, when oil pump need be reprocessed or keep in repair, the dismounting pump cover to change pressure regulation packing ring or rotor, had prolonged the working life of oil pump easily, has reduced manufacturing cost and use cost.
