Abstract
The utility model discloses a rotor shaft oil pump free from jumping from slots. The oil pump comprises a pump body, wherein the top of the pump body is provided with a pump cover; a rotor shaft is arranged in the pump body and assembled with an inner rotor; an outer rotor is arranged outside the inner rotor; the pump cover and the pump body are respectively provided with an oil inlet and an oil outlet; the oil inlet and the oil outlet on the pump cover correspond to the oil inlet and the oil outlet on the pump body; the part of the rotor shaft, extending out of the bottom end of the pump body, is provided with a shaft shoulder; and the diameter of the shaft shoulder is greater than the diameter of the rotor shaft in the pump body. The rotor shaft oil pump free from jumping from slots has the advantage that the shaft shoulder of the oil pump is difficult to jump from the slot and slip.
Description
Technical field
The utility model relates to a kind of oil pump, especially a kind of rotor-type oil pump.
Background technique
Single cylinder diesel normally moves, it is lubricated that the running of too busy to get away oil pump (rotor) axle provides machine oil to do, old-fashioned oil pump is because design deficiency, the maintenance and installation inconvenience, often occur rotor shaft shoulder serious wear in diesel engine work, shaft shoulder wearing and tearing narrow down. and the oil pump shaft shoulder takes off groove and skids, the oil pump work of not turning round, cause diesel engine not lubricated, the generation of faults such as damage.
The model utility content
The purpose of this utility model provides a kind of oil pump shaft shoulder and is difficult for taking off the rotor shaft that groove skids and exempts to take off the scouring machine oil pump.
For achieving the above object, the utility model adopts following technological scheme: a kind of rotor shaft exempts to take off the scouring machine oil pump, comprise that the top is provided with the pump housing of pump cover, be provided with rotor shaft in the pump housing, be equipped with internal rotor on the rotor shaft, internal rotor is provided with external rotor outward, is provided with filler opening and oil outlet on the pump cover and the pump housing, the filler opening of the pump cover and the pump housing, the corresponding setting of oil outlet, the part that rotor shaft stretches out outside the pump housing bottom is provided with the shaft shoulder of diameter greater than pump housing inner rotor shaft diameter.
The diameter of axle at described shaft shoulder place is than the big 9mm-10mm of the diameter of rotor shaft in the pump housing.
The diameter of rotor shaft in the pump housing is 14mm, and the diameter of axle at described shaft shoulder place is 23mm.
The end face of rotor shaft and pump cover contacted inner surfaces is provided with spring groove, is provided with spring in the spring groove.
The thickness of the described pump housing is 30mm.
Be provided with the O RunddichtringO between the external rotor and the pump housing.
The beneficial effects of the utility model are: rotor shaft is oppositely installed on the pump housing, and widens the shaft shoulder diameter of rotor shaft, adds large-diameter, and it is easy to wear to have solved the rotor shaft shoulder, takes off groove and skids, machine oil air pump inoperative, the fragile out of order problem of diesel engine.The pump housing is the ultrathin design of 30mm, exempts to tear open flywheel, makes installation more convenient.The utlity model has the rotor of engine oil pump axle shaft shoulder and be difficult for taking off groove and skid, easy for installation, it is more permanent, more economical to use, and oil lubricating is more unobstructed, reduces wear and tear in machines, increases the service life, and guarantees that diesel engine runs well.
