Abstract
The invention discloses a method for wrapping and retreading a civil aircraft tire by using belted layers, which comprises the following steps of: (1) preparing cord fabric strips; (2) wrapping a first cord fabric layer on a burnished tire body, wrapping the first cord fabric layer by using a wrapping machine in a 0-5 DEG angle with the center line of a tire crown, wherein the gap between the cord fabric strips is not greater than 1 mm, and the final strip and the starting end of the cord fabric strip are on the same horizontal line of the tire surface to form a complete cycle; (3) wrapping a second cord fabric layer by using the wrapping method in the step (2), wherein the second cord fabric layer should cover the gaps in the first cord fabric layer and intersects with the wrapping angle of the first cord fabric layer; and (4) wrapping a mixing rubber strip, and consecutively wrapping a narrow mixing rubber strip on the circumference of the tire for multiple circles. The method reduces the joints at the starting ends and the final ends of the belted layers, so that the rigidity tire body has no section difference and good uniformity. Moreover, the belted layers with the structure have good loop effect, so that the tire has excellent ultrahigh speed durability.
Description
Technical field
The present invention relates to the renovation of civil aviation tire, specifically is to adopt belt to twine the method for renovation civil aviation tire.
Background technology
Civil aviation Aircraft Market develop rapidly both at home and abroad in recent years improves year by year to the demand of civil aviation tire, and the civil aviation tyre rebuilding also rises day by day.As everyone knows, aircraft tyre requires very high to speed ability, and particularly speed is higher than the aircraft tyre of 360km/h, more requires tire to have bigger restraining force to suppress the huge centrifugal force that high speed rotating is brought in the rotation process of high speed, top load.
The ripe method of civil aviation tyre retreading technique mainly adopts the laminating method at present, and the main feature of this method is that technology is simple, easy to operate, but there is following shortcoming in the renovation of laminating method:
1. form minute bubbles easily;
2. delamination appears in binding face easily, thus cause tire in use since the binding face delamination cause get rid of tyre surface;
3. the speed ability of retreads is fit to the tire of speed below 360km/h, is higher than the tire of 360km/h, the easier tyre surface delamination that causes at speed.
4. belt cord termination is many, and few at the attached glue in position, termination, and bond properties is poor, is having under the load condition, when rotating at a high speed, is easy to cause delamination in the cord termination.
Summary of the invention
The objective of the invention is for overcoming the deficiencies in the prior art, and a kind of method that adopts belt to twine renovation civil aviation tire is provided, this retreads can satisfy the serviceability that the civil aviation tire speed is fast, load is high, the carcass sedimentation rate is big.
The technical scheme that realizes the object of the invention is:
Adopt and become 0-5 with the crown center line
oThe winding of strips layer.Concrete grammar comprises the steps:
1, preparation curtain fabric strips: cord is cut into wide 20-30mm, the curtain fabric strips that length is provided with according to tire specification;
2, on the carcass after the polishing, twine the ground floor casing ply, become 0-5 with the crown center line with wrapping machine
oThe angle twine the ground floor casing ply, the slit between the curtain fabric strips is not more than 1mm, curtain fabric strips is terminal to be positioned at the same horizontal line of tyre surface with initiating terminal, forms complete circulation;
3, the winding method with step 2 twines second layer casing ply, and second layer curtain fabric strips should cover the slit between the ground floor curtain fabric strips, and intersects with the arrangement of ground floor winding cord angle;
4, twine mixing adhesive tape, adopt narrow mixing adhesive tape multi-turn to be wrapped in continuously on the circumference of tire, overlap each other between the adhesive tape, form no cord reinforcement tyre surface.
Advantage of the present invention is: the present invention has reduced the joint at belt two ends at the whole story, makes carcass rigidity not have segmentation difference, has fabulous uniformity; And this structure belt has hoop effect preferably, thereby the ultrahigh speed endurance quality of tire is fabulous.
Description of drawings
Fig. 1 renovates the structural representation of civil aviation tire for the present invention;
Fig. 2 is the cutaway view of Fig. 1.
Among the figure: 1. second layer reinforcement casing ply 2. ground floor reinforcement casing plies 3. casingplies 4. reinforcement tyre surfaces 5. intermediate films.
The specific embodiment
The present invention is further illustrated below in conjunction with embodiment, but be not limitation of the invention.
Embodiment:
B737-700/800 type aircraft main tire H44.5 * 16.5-21 28PR renovate method comprises the steps:
1, preparation curtain fabric strips: cord is cut into wide 20-30mm, the curtain fabric strips that length is provided with according to tire specification;
2, on the carcass after the polishing, twine ground floor reinforcement casing ply 2, become 0-5 with the crown center line with wrapping machine
oThe angle twine ground floor reinforcement casing ply 2, the slit between the curtain fabric strips is not more than 1mm, curtain fabric strips end bar and initiating terminal are positioned at the same horizontal line of tyre surface, form complete circulation;
3, the winding method with step 2 twines second layer reinforcement casing ply 1, and second layer reinforcement curtain fabric strips should cover the slit between the ground floor curtain fabric strips, and intersects with the arrangement of ground floor winding cord angle;
4, twine mixing adhesive tape: adopt narrow mixing adhesive tape multi-turn to be wrapped in continuously on the circumference of tire, overlap each other between the adhesive tape, form no cord reinforcement tyre surface 4.
B737-700/800 type aircraft main tire H44.5 * 16.5-21 28PR adopts the tire of this patent winding method renovation as follows with the test contrast situation of the tire that adopts common laminating method renovation:
Evidence: adopt the tire of this patent winding method renovation to compare with the tire that adopts common laminating method renovation, durable, the ultrahigh speed excellent in durability.
