Abstract
The utility model mainly relates to a mechanical displacement pump which is composed of a main shaft, a casing, a driving gear arranged on the main shaft, a driven gear arranged on a driven shaft, a rotor which is positioned on the main shaft in the casing and coaxially provided with the driving gear, and a rotor which is positioned on the driven shaft and is coaxially provided with the driven gear, wherein, teeth and gullets of the two rotors are engaged. The utility model has the characteristics of simple structure, high efficiency, etc., which can be widely used for oil pumps, thick liquid pumps, vacuum pumps, water pumps, motors, blowers, etc.
Description
The utility model belongs to mechanical positive displacement pump, relates generally to the mesh gear pump, structural types such as Roots pump.
At present, the Roots pump of prior art and Roots blower etc., manufacture difficulty is bigger, and precision is difficult for guaranteeing that rotor rotates a circle and has only monolateral increase volume that relative efficiency is low.Though it is simpler that existing gear pump is made, flow is less, and efficient is too low.
The purpose of this utility model is to provide a kind of high working efficiency, highly versatile, and the novel liquid, the gas relative rolling type that are fit to the mesolow seriation of batch process suit pump.
The utility model by main shaft, housing, be installed in the driving gear on the main shaft, be installed in the driven gear on the driven shaft, rotor is installed on the main shaft in the housing, another rotor is installed on the driven shaft in the housing, the tooth and the teeth groove of two rotors are meshing with each other.
In addition, the tooth of each rotor is at least 2.
The utlity model has simple in structure, easy to manufacture, efficient is high, applied range, can be widely used in factory, mine, aviation, automobile and other industries as oil pump, thick liquid pump, vacuum pump, water pump, motor, blower etc.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model sectional view.
Fig. 3 is the rotor structure schematic representation.
Fig. 4, Fig. 5 also are structural representations of the present utility model.
Among the figure: 1 main shaft, 2 driving gears, 3 driven gears, 4 rotors, 5 driven shafts, 6 rotors, 7 housings
Behind main shaft 1 input power, driving gear 2 and coaxial rotor 6 rotates synchronously, and driving gear 2 drives driven gears 3 and rotates with the coaxial rotor 4 of driven gear 3, and the relative rotation of two rotors is divided into malleation chamber and negative cavity to the two ends of housing 7.Because two working rotor teeth along the circular arc move toward one another between root circle and the top circle, dwindle the malleation cavity volume, liquid, gas are extruded.On the contrary, the negative cavity volume increases, and liquid, gas are inhaled into, and the continuous rotation of rotor constantly the moving of tooth of promptly working makes liquid, gas constantly be inhaled into extrusion, the process of finishing the work.
Claims (2)
1, a kind of relative rolling type suits pump, comprise main shaft (1), housing (7), be installed in driving gear (2) on the main shaft (1), be installed in the driven gear (3) on the driven shaft (5), it is characterized in that rotor (6) is installed on the interior main shaft (1) of housing (7), and be installed on the interior driven shaft (5) of housing (7) with driving gear (2) coaxial rotor (4), coaxial with driven gear (3), the tooth and the teeth groove of rotor (4) and rotor (6) are meshing with each other.
2, relative rolling type according to claim 1 suits pump, it is characterized in that the tooth of rotor (4) and rotor (6) is at least 2.
