Embodiment Construction

[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0028] refer to figure 2 , The preferred embodiment of the present invention provides a turbine disc, including a disc 10, an axial hole 11 is provided at the center of the disc 10, and a closed cavity 12 is provided inside the disc 10. In the embodiment of the present invention, by designing a hollow airtight cavity 12 inside the roulette 10, the consumables of the roulette 10 are saved, the structural efficiency of the roulette 10 is greatly improved, and the overall weight of the roulette 10 is reduced. Stress concentration of the wheel 10 is avoided, thereby reducing the weight of the wheel 10 and prolonging the service life of the wheel 10 .

[0029] In this embodiment, in order to ensure the bearing capacity of the wheel 10 and reduce the we...

Abstract

The invention discloses a turbine disk comprising a disk body which is internally provided with a closed cavity. According to the turbine disk, as the hollow closed cavity is formed in the disk body, consumables of the disk are reduced, the structure efficiency of the disk is greatly improved, the whole weight of the disk is reduced, and the stress concentration of the disk is avoided. Therefore, the effects of reducing the weight of the disk and prolonging the service life of the disk are achieved.

Description

technical field [0001] The invention relates to the field of engines, in particular, to a turbine wheel for an engine. Background technique [0002] Discs used in aircraft engines or other gas turbine engines are required to be lightweight and have a long service life. refer to figure 1 , the existing turbine disk includes a disk body 1 and blades 2 arranged on the outer periphery of the disk body 1, wherein the disk body 1 is a solid structure. Because the existing turbine disc adopts the solid structure of the disc body 1, the weight of the turbine is increased, and the stress degree of not all parts of the turbine is very high during operation, and the stress of some internal parts is relatively small, so As a result, the material utilization rate of the existing turbine is low, and the stress of the wheel disc is high or the weight is heavy. Contents of the invention [0003] The purpose of the present invention is to provide a turbine wheel to solve the existing te...
