Abstract
The invention discloses an external-rotor rotational connector. The invention comprises an inner ring formed by a hollow flange and an outer ring sheathing the inner ring and rotating. The inner wall of outer ring is arranged with grooves axially at different positions and circumference. The grooves are communicated with the axial channels on the cylinder of outer ring. The flange ring at one end of inner ring is arranged with holes on the outer wall. The axial channels at the axle of inner ring of flange are communicated to the grooves. The invention can fix the inner ring and rotate the outer ring.
Description
Technical field
The present invention relates to a kind of mechanical splice, more particularly, relate to a kind of swivel joint that comprises that water, oil and cable, water pipe connect.
Background technique
Traditional jointing generally needs fixedly outer ring, relies on the inner ring rotation to realize certain mechanical function.Problem is, needs in some mechanical structure that inner ring is fixed, the outer ring rotation, this be because this moment inner ring need pass elastic cable paper or water pipe, must be fixing.
Summary of the invention
The present invention is directed to the fixedly joint form of inner ring of above-mentioned needs, a kind of external rotor type rotary joint is provided, be intended to solve because inner ring need be worn elastic cable paper or water pipe the joint problem that fixing inner ring requires the outer ring rotation simultaneously.
In order to address the above problem, the present invention has constructed a kind of external rotor type rotary joint, comprises the inner ring 4 that is made of hollow flange and is enclosed within outer ring 5 in relative rotation, inner ring outside.The inwall of outer ring 5 is at axial diverse location, along the circumferential direction offer groove 1b, 2b, 3b.Cell body 1b, 2b, 3b are communicated with path 1c, 2c, the 3c that offers vertically respectively on the cylindrical shell of outer ring 5.On outer wall, offer hole 1,2,3 on the flange plate of inner ring one end, and be communicated in cell body 1b, 2b, 3b respectively by the path of axially offering along the flange inner ring.
In addition, in order to guarantee sealability, the interval of the inwall of outer ring 5 between groove 1b, 2b, 3b is provided with sealing 6.
By technique scheme, external rotor type rotary joint of the present invention can realize effectively that inner ring is fixed, the joint form of outer ring rotation.
Description of drawings
Fig. 1 is the surface structure schematic representation of external rotor type rotary joint of the present invention;
Fig. 2 is the sectional view of external rotor type rotary joint among Fig. 1, wherein shows with revolved sectional view in the outer ring.
Embodiment
As shown in Figure 1, with reference to figure 2 explanations, external rotor type rotary joint of the present invention, its inner ring 4 is fixing hollow flange.Outer ring 5 is a rotor, and bearing externally is set usually, and under the fixing prerequisite in axle center, outer ring, rotate the outer ring.
As shown in the figure, on the flange plate of inner ring one end, on outer wall, offer hole 1,2,3, and, distinguish intercommunicating pore 1,2,3 along path 1a, 2a, 3a that the flange inner ring is axially offered.Path is blocked in end (1a, 2a, 3a place among the figure) at path, and this position perforate is in order to realize the purpose of path processing.In addition, as shown in Figure 2, the inwall of outer ring 5 is at axial diverse location, along the circumferential direction offer groove 1b, 2b, 3b, and cell body 1b, 2b, 3b are communicated with path 1c, 2c, the 3c that offers vertically respectively on the cylindrical shell of outer ring 5.At this moment, as shown in the figure, except that 1a, 2a, 3a aperture were plugged, hole 1,2,3 was communicated with respectively with groove 1b, 2b, 3b and path 1c, 2c, 3c.Need explanation, path 1c, 2c, 3c are provided with along the diverse location on the circumference of outer ring among Fig. 2, and the mode that this figure cuts open with rotation shows, so that structure of the present invention clearly is described.In addition, in order to guarantee sealability, the interval of the inwall of outer ring 5 between groove 1b, 2b, 3b is provided with seal ring 6.
Certainly, the quantity of above-mentioned hole and path is set as required, can be one, two, four even more, and the variation of quantity is the mode that is equal to mutually with main points that the present invention protects.In addition, the hollow flange of inner ring can pass cable and other pipeline such as water pipe etc.
Swivel joint of the present invention is connected by inner ring and outer ring, relies on the seal ring of joint to realize the fixing of joint.The outer ring can connect centering by bearing, and can bear certain load pressure.
The above; only be the preferable embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technological scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
Claims (2)
1, a kind of external rotor type rotary joint is characterized in that, comprises the inner ring (4) that is made of hollow flange and is enclosed within inner ring outside outer ring (5) in relative rotation;
The inwall of described outer ring (5) is at axial diverse location, along the circumferential direction offer groove (1b, 2b, 3b); Described cell body (1b, 2b, 3b) is communicated with the path of offering vertically (1c, 2c, 3c) respectively on the cylindrical shell of described outer ring (5);
On outer wall, offer hole (1,2,3) on the flange plate of described inner ring one end, and be communicated in described cell body (1b, 2b, 3b) by the path of axially offering along the flange inner ring.
According to the described external rotor type rotary joint of claim, it is characterized in that 2, the interval of the inwall of described outer ring (5) between described groove (1b, 2b, 3b) is provided with seal ring (6).
