Abstract
The utility model is related to a kind of seal structure of gear shaft inner hole, including gear shaft and seal plug, the material of described seal plug is copper alloy, it is rounded, the position of periphery is provided with axial extension, extension coordinates with gear shaft inner hole, after seal plug is arranged on gear shaft inner hole, gear shaft inner hole is obturaged using the mode of circumferential rolling.The utility model can realize effectively obturaging for endoporus, and the characteristics of with non-aging, long lifespan.
Description
Technical field
The utility model is related to a kind of seal structure, especially a kind of seal structure of gear shaft inner hole, can with sealing
The characteristics of by, long service life.
Background technology
In traditional aircraft product design, from from the point of view of loss of weight, gear shaft generally processes endoporus, but for some
Gear shaft is isolated with free surrounding space, it is necessary to endoporus is obturaged.The structure of current use of generally obturaging is using blanking cover+sealing ring+gear
Coil structures, it is relative complex, while sealing ring belongs to nonmetallic materials, work in high temperature environments for a long time, easy aging, the life-span
Short, reliability is not high.
The content of the invention
The purpose of this utility model is to provide a kind of bore seal structure, it is possible to achieve the effective of endoporus obturages, and
And the characteristics of with non-aging, long lifespan.
Concrete technical scheme of the present utility model is, a kind of seal structure of gear shaft inner hole includes gear shaft and close
Closure, the material of described seal plug is copper alloy, rounded, and the position of periphery is provided with axial extension, is extended
Part coordinates with gear shaft inner hole, after seal plug is arranged on gear shaft inner hole, using the mode of circumferential rolling by gear shaft inner hole
Obturage.
The utility model has used copper alloy seal plug, can enter work in hot environment for a long time, it is ensured that use
Life-span；After seal plug is arranged on endoporus, rolled, mating part is produced the deformation of radial direction, both can guarantee that seal plug
Installation site fix, while further enhancing effect of obturaging.Therefore, the utility model can realize effective envelope of endoporus
Sternly, the characteristics of and with non-aging, long lifespan.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
The copper blanking cover schematic diagram that Fig. 2 is related to for the utility model.
Specific embodiment
As illustrated, a kind of seal structure of gear shaft inner hole includes gear shaft 1 and seal plug 2, described seal plug 2
Material is copper alloy, rounded, and the position of periphery is provided with axial extension, and extension is matched somebody with somebody with the endoporus of gear shaft 1
Close, seal plug 2 is arranged in gear shaft behind 1 hole, the endoporus of gear shaft 1 is obturaged using the mode of circumferential rolling.
