Abstract
The utility model provides the radial axle bearing used on a kind of screw rod drilling tool motor and screw pump.A kind of currently known three screw pump, it is made up of a male rotor, two female rotors for being arranged symmetrically in male rotor both sides and housing.The angle at male rotor center and the line at two female rotor centers is designed to be less than 90 degree by screw drilling tool motor or screw pump of the present utility model, then in the case where shell inner hole largest contours are equal sized, can increase by more than 50% area of passage.Female rotor and male rotor both ends are equipped with journal bearing, avoid male rotor and female rotor because bearing to wear caused by radial load.One end of radial axle bearing is designed with ear, and the hole that male rotor is passed through in the external diameter and motor shell of ear matches, and can prevent radial axle bearing from rotating.
Description
Technical field
It the utility model is related to screw drilling tool motor and screw pump, especially all-metal screw driller motor and screw pump
Structure type.
Background technology
Currently known a kind of three screw pump, by a male rotor, two female rotors for being arranged symmetrically in male rotor both sides
Formed with housing, due to male rotor force in radial complete equipilibrium, so without journal bearing.Its shortcoming is：Applied to narrow and small
Well in, then the problem of screw pump area of passage is less than normal be present.
As shown in Fig. 2 by male rotor（5）Center and two female rotors（6）The angle of the line at center is designed to 75 degree of left sides
The right side, when currently known motor shell（1）External diameter and the motor shell of the present invention（4）It is when external diameter is equal, then of the present utility model
Motor area of passage is than currently known screw pump or motor area of passage increase by more than 50% as shown in Figure 1.But male rotor will
Radial load is born, and the medium of underground often contains solid phase particles, so female rotor and male rotor both ends are equipped with journal bearing,
Male rotor and female rotor are avoided because bearing to wear caused by radial load.
The content of the invention
The technical problems to be solved in the utility model is：When rotor rotates, radially vicarious seat follows rotation.
The technical scheme that the utility model is taken is：One end of radial axle bearing is designed with positioning ear.
The beneficial effects of the utility model are：When rotor rotates, radial axle bearing will not follow rotation.
Brief description of the drawings
Fig. 1 is currently known three screw pump cross-sectional view.
Fig. 2 is the utility model all-metal screw driller motor or screw pump cross-sectional view.
Fig. 3 is the front view of the utility model radial axle bearing.
Fig. 4 is the left view of the utility model radial axle bearing.
Embodiment
Due to the female rotor in currently known screw pump or motor as shown in Figure 1（3）It is arranged symmetrically in male rotor（2）
Both sides, therefore male rotor（2）It is not subject to radial load.But the male rotor in screw pump of the present utility model or motor（5）Bear to compare
Larger radial load, and the medium of underground often contains solid phase particles, so female rotor and male rotor both ends are equipped with journal bearing
With radial axle bearing（7）, male rotor and female rotor are avoided because bearing to wear caused by radial load.
As shown in figure 3, in order to avoid in motor shell（4）On be provided with pin-and-hole, improve motor shell（4）Reliability, will
Radial axle bearing（7）One end be designed with ear（8）, ear（8）External diameter and motor shell（4）Middle male rotor（5）Passed through
Hole（11）Match, radial axle bearing can be prevented（7）Rotate.
Claims (1)
1. the male rotor of the radial axle bearing used on a kind of new screw motor or screw pump, screw motor or screw pump
Center and the angle of the line at two female rotor centers are less than 90 degree, and rotor is subjected to radial load, and journal bearing is housed on rotor,
It is characterized in that：The ear of radial axle bearing stretch into the parallel interior bores of housing serve it is circumferentially positioned.
