Description

Pumping bearing structure

Technical field

The utility model is relevant with pumping bearing structure, espespecially a kind of bearing of pressure pumping.

Background technique

The structure of known pressure pumping as shown in Figure 8, it is the top flat 73 that deflection is arranged on a driveshaft 72 by the rotating shaft 71 relative to a motor, reciprocal axial displacement is produced, to form pressurization to the current flowing through pumping when the driving being subject to rotating shaft 71 is rotated.For making driveshaft 72 or top flat 73 be formed relative to rotating shaft 71 in arranging on the bias, then rotating shaft 71 first need be socketed a conversion adapter 74, and this conversion adapter 74 is connected to a bearing 75 again, and this bearing 75 is connected to each driveshaft 72 again.Wherein the axis hole 741 of conversion adapter 74 is the inclined hole departing from its axle center, presents deflection shape after being socketed on rotating shaft 71 for it, and then makes the bearing 75, driveshaft 72 and the top flat 73 also related formation deflection that are connected to conversion adapter 74.

Above-mentioned conversion adapter 74 is generally plasthetics, and under rotating shaft 71 high speed rotating, conversion adapter 74 is easily worn and reduces the adaptation between itself and rotating shaft 71, and then is difficult to the rotation of accurate transfer rotating shaft 71 and affects the usefulness of pressure pumping.What is more, installing conversion adapter 74 will cause the increase of the number of components, wearing and tearing therefore between component and leak chance also by related aggravation, so that increase maintenance cost, the necessity had much room for improvement in fact.

Model utility content

Main purpose of the present utility model is to provide a kind of pumping bearing structure, and its internal axle sleeve in bearing is wholely set one and tiltedly bores a hole, and makes in its rotating shaft being installed in a motor and namely directly forms deflection setting, have effect of simplified structure.

For reaching aforementioned object, the utility model by the following technical solutions:

A kind of pumping bearing structure, it includes:

One internal axle sleeve, it has one first end face and one first bottom surface, and this first end face and this first bottom surface are parallel to each other, and has one axially in the definition of the center of this internal axle sleeve;

One first tiltedly bores a hole, and it is integrally provided on this internal axle sleeve and is through to this first bottom surface from this first end face; This first tiltedly perforation bearing of trend relative tilt in this internal axle sleeve axis and define an angle of inclination;

One external axle sleeve, it is located at the periphery of this internal axle sleeve and can rotates relative to this internal axle sleeve, and is provided with several roll piece between this external axle sleeve and this internal axle sleeve.

Wherein, this first oblique perforation includes a curved portions and a par.

Further, in another embodiment, this first par of tiltedly boring a hole is arranged with a groove extended along this first bearing of trend of tiltedly boring a hole.

Moreover the first bottom surface of this internal axle sleeve is provided with a pad, this pad has one second end face and one second bottom surface, and this second end face with to should the angle relative tilt at angle of inclination in this second bottom surface.

The utility model has the advantage of:

The component that the utility model can simplify conversion adapter is arranged, and after the number of components reduces, improves the wearing and tearing between component and situation of leaking simultaneously.

Embodiment

Refer to Fig. 1,2, be depicted as the first embodiment of pumping bearing structure provided by the utility model, it includes internal axle sleeve 1 and an external axle sleeve 2, and wherein external axle sleeve 2 is located at the periphery of internal axle sleeve 1, and can rotate relative to internal axle sleeve 1.Be provided with several roll piece 3 between external axle sleeve 2 and internal axle sleeve 1, in order to reduce the frictional force between external axle sleeve 2 and internal axle sleeve 1, be beneficial to relatively rotating between the two.

Internal axle sleeve 1 has one first end face 11 and one first bottom surface 12, and in the present embodiment, the first end face 11 and the first bottom surface 12 are parallel to each other, and the definition of the center of internal axle sleeve 1 has an axial C1, and wherein axial C1 is simultaneously perpendicular to end face 11 and bottom surface 12.

Hold, one first tiltedly perforation 13 is integrally formed with in internal axle sleeve 1, first tiltedly perforation 13 be through to the first bottom surface 12 from the first end face 11, and define and have a central shaft C2 in order to represent the bearing of trend of tiltedly perforation 13, central shaft C2 relative tilt is in the axial C1 of internal axle sleeve 1; In other words, first tiltedly define between the bearing of trend of perforation 13 and axial C1 there is a tilt angle theta.

In addition, in the present embodiment, the shape of the first oblique perforation 13 includes curved portions 131 and a par 132, when establishing for the rotating shaft group corresponding with a shape, par 132 produces the effect of a stopper rotating shaft, and can drive internal axle sleeve 1 synchronous axial system in axis of rotation.

When bearing structure of the present utility model is assembled on pressure pumping, as shown in Figure 3, the rotating shaft 41 of motor is mounted in the first oblique perforation 13 of internal axle sleeve 1, because first tiltedly bores a hole 13 in deflection shape, solid bearing directly can be made to present deflection shape relative to rotating shaft 41, and then make the driveshaft 42 that is mounted on the utility model bearing and top flat 43 also present deflection shape relative to rotating shaft 41.Accordingly, when rotating shaft 41 is rotated, internal axle sleeve 1 rotates with producing beat, makes driveshaft 42 and top flat 43 form reciprocal displacement, to pressurize to the current flowing through pumping.Compared to known structure, the component that the utility model can simplify conversion adapter is arranged, and after the number of components reduces, improves the wearing and tearing between component and situation of leaking simultaneously.
