Abstract
The utility model relates to a component on a metal cross-flow fan, in particular to a steel shaft component, which is formed by a steel shaft (1), an aluminum sleeve (2) and a circular connecting plate (3) with a mounting hole, wherein the aluminum sleeve (2) is sleeved on the bottom end of the steel shaft (1), the aluminum sleeve (2) is arranged on the mounting hole of the circular connecting plate (3), and the steel shaft (1), the aluminum sleeve (2) and the connecting plate (3) are fixed at the mounting hole in riveting way. The steel shaft component has the advantages of simple structure, convenient production, free temperature change affects, excellent stability and the like.
Description
Technical field
The utility model relates to the component on a kind of metal axial-flow fan, relates in particular to the steel shaft assembly on the metal axial-flow fan.
Background technique
At present, the steel shaft assembly is the important spare part on the metal axial-flow fan, and it is fixed in the impeller mid-game of axial-flow fan.Existing steel shaft assembly is connected mould by the steel axle with the plastics Reinforced Nylon and constitutes, annular knurl is arranged at steel axle bottom, this part with stretch into the plastics Reinforced Nylon and be connected in the mould and and fix with it, the card base that about plastics Reinforced Nylon connection mould is provided with stagger in two-layer position, it is corresponding with the positioning hole shape in the impeller mid-game that the plastics Reinforced Nylon connects mould, the rotary plastic Reinforced Nylon connects mould, and the positioning hole that the card base that staggers in two-layer up and down position blocks in the impeller mid-game is realized the fixing of steel shaft assembly and impeller mid-game.The defective that existing steel shaft assembly exists is: the distortion of plastics Reinforced Nylon temperature influence is big, size is difficult to control, embrittlement and aging easily, and the perpendicularity of steel axle and impeller mid-game can not guarantee, the steel shaft assembly be assembled in the impeller mid-game because size and mutually the variation of perpendicularity that the two cooperation can take place is improper, poor stability causes the impeller big situation of beating to influence its quality of processing and efficient, and the plastics card base also is easy to fracture simultaneously.
Summary of the invention
The purpose of this utility model is in order to solve the technological deficiency that existing steel shaft assembly exists, disclose a kind of simple in structure, be not acted upon by temperature changes, the steel shaft assembly of good stability.
In order to realize above-mentioned purpose, the utility model has adopted following technological scheme:
A kind of steel shaft assembly is made of steel axle, aluminium cover and the ring connecting sheet that has a mounting hole, and the aluminium cover is set on the bottom of steel axle, and aluminium is set on the mounting hole place of ring connecting sheet, and steel axle, aluminium cover and connecting sheet are fixed at mounting hole place riveted.
As preferably, described connecting sheet be provided with the impeller mid-game on the locating slot that is complementary of positioning hole, be convenient to the fixing of steel shaft assembly and impeller mid-game, this mode is simple in structure, makes and easy for installation.
As preferably, the position of described steel axle is located at the circle centre position of connecting sheet, has guaranteed the stability of steel shaft assembly.
As preferably, the bottom of described steel axle is connected part with the aluminium cover and is provided with the reticulate pattern annular knurl, has increased the frictional force that steel axle and aluminium overlap the joint, makes mutual connection tightr.
Owing to adopted a kind of steel shaft assembly of above-mentioned technological scheme, fixedly constitute by steel axle, aluminium cover and connecting sheet riveted, this steel shaft assembly is simple in structure, be convenient to production and processing, while steel shaft assembly is beated little after being assembled in the impeller mid-game each other, and the perpendicularity of steel axle and impeller mid-game is good, all adopt metal to connect, be not acted upon by temperature changes, good stability has improved the quality of processing and the efficient of product.In sum, this steel shaft assembly have simple in structure, easily manufactured, be not acted upon by temperature changes the advantage of good stability.
Description of drawings
Fig. 1: the utility model embodiment's structural representation.
Fig. 2: the A-A generalized section among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing 1, Fig. 2 embodiment of the present utility model is made a detailed explanation.A kind of steel shaft assembly as shown in Figure 1 and Figure 2 is made of steel axle 1, aluminium cover 2 and the ring connecting sheet 3 that has a mounting hole.Aluminium cover 2 is set on the bottom of steel axle 1, and the bottom of steel axle 1 is provided with reticulate pattern annular knurl 11 with aluminium cover 2 parts that are connected, and has increased steel axle 1 and the frictional force that aluminium overlaps 2 joints, makes mutual connection tightr.Aluminium cover 2 is arranged on the mounting hole place of ring connecting sheet 3, and steel axle 1, aluminium cover 2 and connecting sheet 3 are fixed at mounting hole place riveted, and the position of steel axle 1 is located at the circle centre position of connecting sheet 3, has guaranteed the stability and the concentricity of steel shaft assembly.Connecting sheet 3 be provided with 3 with the impeller mid-game on 4,3 locating slots 4 of locating slot of being complementary of positioning hole be used for positioning hole riveted fixing with the impeller mid-game.
What aluminium cover 2 adopted is pure aluminium material, and material is softer, and the material of connecting sheet 3 is steel, the preferred ST12 of the trade mark, and aluminium cover 2 is fixed steel axle 1 and connecting sheet 3 riveteds through extruding.
The foregoing description only is a this patent mode of execution preferably, and the structure that all employing the technical program are described, feature and the variation on its spiritual principle, modification all belong to the protection domain of this patent.
