In order to reduce vibration and noise, the basic structure of the shuttle wheel of the shuttle in the rail pair comprises a steel ring and a wheel body, the wheel body is generally made of elastic high polymer materials, and is in a circular structure, namely the profile of the axial section of the shuttle wheel is a circular arc line, such as the related content disclosed by patent documents such as CN201620521681.0, CN201520594928.7 or CN201020622729.X, and the like, the shuttle wheel is matched with conical surface rails of an upper door ring and a lower door ring to be in theoretical point contact, even if a certain shape track exists in the wheel body, the contact area of the shuttle wheel and the rail is extremely small, so that the stress borne by the wheel body is extremely large, and the included angle between the current conical surface bus of the conical surface rail and the horizontal plane is 20-25 degrees, namely the included angle between the counter force of the rail to the shuttle wheel and the centrifugal force is 65-70 degrees, the actual counter force is amplified to 2.36-2.92 times of the centrifugal force; the outer diameter of the shuttle wheel is smaller, the outer diameter of the shuttle wheel of the existing four-shuttle circular loom is only 50mm, if the actual working time of the circular loom is 20 hours per day, the track diameter of the shuttle wheel is 1000mm, and the running speed of the shuttle is 200r/min, the running mileage of the shuttle wheel per day is 753600m (pi is 3.14), the shuttle wheel runs 480 ten thousand turns per day, and therefore the service life of the shuttle wheel and the bearing thereof can be directly influenced if the outer diameter of the shuttle wheel is too small; thirdly, as the wheel body is in a circular structure, the angle of the rotating shaft center line of the shuttle wheel arranged on the shuttle body of the shuttle is not strictly required, once the wheel body is worn, the wheel body and the track are not in a pure rolling state any more, and the wear of the wheel body is accelerated. The speed of the current circular weaving machine is continuously improved, but the centrifugal force of the circular motion of the shuttle is in direct proportion to the square of the rotating speed, the contradiction that the service life of the shuttle wheel is short is particularly prominent, the service life is only 1-2 days at present, so that a user only needs to frequently replace the shuttle wheel, and the cost and the working efficiency are influenced.

The structure of the upper and lower runways is not disclosed, so the structure of the shuttle wheel matched with the upper and lower runways cannot be known, but the date disclosed by the patent application document is 11/2 in 2005, nearly 14 years till now, however, the shuttle wheel with a circular structure is still widely adopted in the market, and the problem of low service life is not solved. In addition, CN105088494A discloses that more than 2 conical positioning shuttle wheels (17) are respectively installed at the upper and lower sides of the inner side of the shuttle body, and the conical angle of the conical positioning shuttle wheels is in rolling contact with the inclined surface steps on the inner planes of the upper and lower door rings, but the inclined directions of the two inclined surfaces are intersected towards the center direction of the door ring.

As for the shuttle wheel, because the shuttle wheel forms the pure rolling cooperation of line contact when contacting with the conical surface track, contact length has been greater than prior art by 3 at least times, and unit contact stress and deformation reduce by a wide margin, consequently can further improve the life of shuttle wheel more than 3 times, compare prior art, the life of shuttle wheel can double, the number of times that the shuttle wheel was changed has significantly reduced, and is very clear and definite to the improvement of production efficiency.
