A Method for Static Balance Correction of Aviation Tire

Abstract

The invention relates to the technical field of aviation tire manufacturing, in particular to a method for calibrating the static balance of the aviation tire. When the static balance of the tire needs to be corrected, the weight of the tread rubber at the "key" part is reduced by grinding the tread rubber at the "key" part at an interval of 180° from the "light point" of the aviation tire, and the "key" part is reduced. The static balance difference between the "light point" and the "key" part, and by controlling the amount of tread rubber to be polished off, the static balance difference between the "light point" and the "key point" meets the specified requirements to achieve the correct static purpose of balance. The method provided by the present invention does not need to add additional attachments, does not need to use adhesives and other pasting operations, does not damage the inner liner of the tire, does not affect the retreading of the tire, and is simple, safe and easy to operate.

Description

technical field [0001] The invention relates to the technical field of aviation tire manufacturing, in particular to a method for calibrating the static balance of the aviation tire. Background technique [0002] In the manufacturing process of aviation tires, due to the large number of components and complex processes, affected by many factors such as component tolerances, equipment tolerances, and operator operations, the static balance difference of the finished aviation tires manufactured may exceed the specified range. Vibration of the landing gear may be induced during takeoff. Therefore, after the manufacture of aviation tires, it is necessary to carry out static balance performance testing, and perform static balance correction for tires exceeding the standard static balance difference, so as to make their static balance meet the requirements. [0003] The traditional correction method is to add a balance patch made of high-density material to the inner side of the ...

Problems solved by technology

The traditional method has several disadvantages: (1) It is necessary to process the special rubber material and adhesive for the large-density balance patch, make the balance patch, paste the balance patch, heat and press vulcanize the pasted balance patch

Time-consuming, labor-intensive and material-intensive, increasing process, consumption and cost; (2) It is necessary to polish the inner part of the tire, which may damage the air-tightness of the tire, posing a safety hazard; (3) the balance patch (not shown in the figure) during use Drawn) is easy to fall off, causing safety accidents; (5) when retreading tires, it is difficult to remove the balance patch, or the tire inner liner is damaged when the balance patch is removed, which affects the retreading quality of the tire
