Abstract
The utility model relates to an oil pump, especially a novel external rotor driving motor oil pump, comprising a pump body, an external rotor, an internal rotor and a shaft. The utility model is characterized in that the pump body is the inner cavity of a drive gear; the external diameter of the external rotor is provided with a pin which is connected to the drive gear; the internal rotor is disposed on the shaft so that an eccentric throw exists between the internal and the external rotor; the shaft is fixedly connected to a supporting shaft; the other end of the drive gear is provided with the supporting shaft which is provided with an oil inlet/outlet; the oil inlet/outlet is communicated with the pump body, thereby the input and output of oil can be achieved. The utility model has advantages of possessing novel and simple structure; reducing volume; saving the space for an engine.
Description
Technical field
The utility model relates to oil pump, particularly a kind of novel external rotor driving machine oil pump.
Background technique
Prior art is generally, the structure of rotor-type oil pump is that driving gear connects with driving shaft, power is passed to the oil pump internal rotor by driving shaft, drive the external rotor rotation by rotation of inner rotor, because inside and outside rotor has a throw of eccentric when cooperating, therefore in the inner and outer rotors rotation process, just machine oil is sucked from oil sucting cavity, extrude by pumping cavity again, finish the pump oil process of oil pump.This is a kind of traditional product, show on the structure also not really compact, the space that especially can not save motor more.
The model utility content
The purpose of this utility model is at above-mentioned defective, and a kind of more compact structure is provided, and more saves the novel external rotor driving machine oil pump between engine air.
The technical solution of the utility model is novel external rotor driving machine oil pump, comprises the pump housing, external rotor, internal rotor and axle, it is characterized in that the described pump housing is the inner chamber of driving gear one end axle, has pin to connect with driving gear on the external rotor external diameter; Internal rotor is installed in and makes internal rotor and external rotor that a throw of eccentric is arranged on the axle, and this axle is installed on the supporting axle and is fixedly connected; Being equipped with in the driving gear the other end axle on back shaft and this supporting axle has the turnover oilhole, and this turnover oilhole is communicated with the pump housing is interior, realizes the input and the output of machine oil.
There are three pins to connect on the described external rotor external diameter with driving gear.
The utility model has the advantages that because the inner chamber of driving gear one end axle is arranged to oil pump pump housing lumen pore size, directly connect by external rotor with driving gear, make oil pump structurally compacter more, thereby also just saved the installing space of motor than traditional product.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the right side view of Fig. 1.
Embodiment
With reference to Fig. 1, Fig. 2,1-driving gear, 2-external rotor, 3-internal rotor, 4-lining, 5-driving pin, 6-lock ring, 7-pump shaft, 8-nut, 9-back shaft.Innovative point of the present utility model is the structure in the past that has changed oil pump, changing external rotor into by traditional internal rotor driving drives, directly connect by driving gear with external rotor, the driving gear inner chamber is designed to the pump housing lumen pore size of oil pump, by three pins gear is connected with the external rotor external diameter, when rotating, gear drives the external rotor rotation, internal rotor then be by with external rotor have a throw of eccentric the axle be that back shaft supports, driving internal rotor rotates on axle, thereby finish the oil suction of oil pump, press oil work, supporting axle is provided with the turnover oilhole, to realize the suction and the extrusion of machine oil.Make the machine oil pump structure compact more on the whole, the space of also further having saved motor.As shown in Figure 1, the inner chamber of driving gear 1 one end axles is set to the pump housing lumen pore size of oil pump, and external rotor 2 is installed in the lumen pore; Corresponding internal rotor 3 is installed on the pump shaft 7, and make internal rotor 3 and external rotor 2 that throw of eccentric be arranged, and back shaft 9 is installed in driving gear 1 the other end axle axle, back shaft 9 is provided with the turnover oilhole, this turnover oilhole is communicated with pump housing inner chamber, realizes the input and the output of machine oil.Pump shaft 7 is installed in has nut 8 to be fastenedly connected on the back shaft 9; Have driving pin 5 to connect with driving gear 1 on external rotor 2 external diameters, such pin has three.Driving pin 5 also is equipped with lining 4 at pump housing interior section, and driving pin 5 is provided with lock ring 6 on the part of driving gear 1.
Claims (2)
1. novel external rotor driving machine oil pump comprises the pump housing, external rotor, internal rotor and axle, it is characterized in that the described pump housing is the inner chamber of driving gear one end axle, has pin to connect with driving gear on the external rotor external diameter; Internal rotor is installed in and makes internal rotor and external rotor that a throw of eccentric is arranged on the axle, and this axle is installed on the supporting axle and is fixedly connected; Being equipped with in the driving gear the other end axle on back shaft and this supporting axle has the turnover oilhole, and this turnover oilhole is communicated with the pump housing is interior, realizes the input and the output of machine oil.
