Problems solved by technology
Since the lubricating oil tank support is arc-shaped and has a certain radian, and the rubber pad has good plastic elasticity, the tightness around the rubber pad and the fuel tank support is difficult to meet the requirements during repair, which seriously affects the repair effect and efficiency of the rubber pad.

The invention relates to the technical field of aero-engines, in particular to a method for repairing a rubber pad on a lubricating oil tank support of an aero-engine. The method for repairing the rubber pad comprises the following steps: firstly, an old rubber pad is removed; then, the surface of the lubricating oil tank support and the surface of a new rubber pad are coated with adhesives, and the new rubber pad is pre-installed on the lubricating oil tank support for preliminary positioning; and finally, the fitting tightness of the new rubber pad and the lubricating oil tank support is improved through a rubber pad repairing tool manufactured through the method, so that the fitting tightness of the new rubber pad and the lubricating oil tank support meets the requirement, and the repairing work of the rubber pad on the lubricating oil tank support is completed. According to the manufactured rubber pad repairing tool, the connecting strength of the new rubber pad and the lubricating oil tank support can be rapidly guaranteed, the repairing effect and efficiency of the rubber pad on the lubricating oil tank support of the aero-engine are effectively improved, repairing can be conducted at the normal temperature, and on-site rapid repairing and using of the aero-engine are facilitated.
Description
technical field [0001] The invention relates to the technical field of aero-engines, in particular to a method for repairing rubber pads on the support of an aero-engine lubricating oil tank. Background technique [0002] The aero-engine oil tank is installed on the oil tank bracket, and is tightly connected with the engine through the oil tank bracket. The rubber pad with positioning piles is connected with the positioning holes of the oil tank bracket through two positioning piles, so as to avoid the oil tank and the oil tank bracket. Direct contact reduces wear between the lubricating oil tank bracket and the lubricating oil tank, and plays the role of slowing vibration. Due to the impact of the harsh external environment and vibration during flight, the rubber pad positioning pile often breaks, causing the rubber pad to slip out, and in severe cases, it can cause the fuel tank to collide with the bracket and leak. [0003] When the rubber pad positioning pile breaks, th...
