Abstract
The utility model belongs to the technical field of aviation machines, and particularly relates to a barrel-shaped nut assembly. The barrel-shaped nut assembly comprises a barrel-shaped nut (1) and a support (2). The barrel-shaped nut (1) is divided into three sections, the upper section (101) is of a cylindrical structure, the middle section (102) is of a square body structure, and the lower section (103) is of a barrel-shaped structure. The section of the support (2) is of a circular arc shape. The barrel-shaped nut assembly has the advantages of being stable in mechanical property, high in installation reliability and the like, repeated labor caused by external factors can be greatly reduced, the installation reliability is improved, and the fatigue and vibration performance of the nut is improved through metal self-locking of the nut.
Description
Technical field
The utility model belongs to aviation machine technical field, particularly relates to a kind of barrel nut assembly.
Background technique
The installation connecting element of the motor of type aircraft require the mechanical property of connection standard part require high, install reliable and stable.Owing to being subject to the restriction that motor installing space is little, installation and removal are subject to various conditions, require the necessary stable mechanical performance of link of motor and install reliably, reduce the dismounting number of times of motor as far as possible.Novel barrel-shaped nut assembly is on the basis of former barrel nut assembly, carry out improving design, increase nut error protection design and nut self-locking property, prevented barrel nut assembly when mounted, because the extraneous factor such as artificial causes the nut setup error in barrel nut assembly; And by increasing nut self-locking property, improve the Fatigue Vibration performance of nut assembly.
Summary of the invention
Goal of the invention: a kind of barrel nut assembly is provided, can improves nut self-locking property, improve the Fatigue Vibration performance of nut assembly.
Technological scheme
A kind of barrel nut assembly, comprises a barrel nut 1, support 2 and locating stud 3, and described barrel nut 1 is divided into three sections, and epimere 101 is round column structure, and stage casing 102 is tetragonal body structure, and hypomere 103 is barrel shaped structure.Described support 2 cross sections are circular arc, and support upper end 201 is provided with for laying and the restraining groove 202 of fixing barrel nut 1, and support lower end 203 is provided with the barrel-shaped perforate 204 coordinating with the hypomere 103 of barrel nut 1.
The stage casing 102 both sides diagonal positions of described barrel nut 1 have two fixed holes 104, and restraining groove 202 relevant positions of described support 2 have two through holes 205, and described barrel nut 1 is fixed on support 2 by locating stud 3.
Described barrel nut 1 is by making epimere 101 distortion have auto-lock function.
Beneficial effect
A kind of barrel nut assembly of the utility model has stable mechanical performance, installation reliability high, can reduce in a large number due to the duplication of labour that caused by extraneous factor and improve the reliability of installing, having improved nut Fatigue Vibration performance by nut metal self-locking.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is barrel nut structural representation;
Fig. 3 is supporting structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, refers to Fig. 1 to Fig. 3.
As shown in Figure 1, a kind of barrel nut assembly, comprises a barrel nut 1, support 2 and locating stud 3.Described barrel nut 1 is divided into three sections, and epimere 101 is round column structure; Stage casing 102 is tetragonal body structure; , hypomere 103 is barrel shaped structure.Described support 2 cross sections are circular arc, and support 2 circular sections contact with structure, can effectively reduce because nut extrusion structure itself makes structure generation distortion; Support upper end 201 is provided with for laying and the restraining groove 202 of fixing barrel nut 1, and this restraining groove 202 contacts with the tetragonal body lower surface in barrel nut 1 stage casing 102; Support lower end 203 is provided with the barrel-shaped perforate 204 coordinating with the hypomere 103 of barrel nut 1.
The stage casing 102 both sides diagonal positions of described barrel nut 1 have two fixed holes 104, and restraining groove 202 relevant positions of described support 2 have two through holes 205, and described barrel nut 1 is fixed on support 2 by locating stud 3.While preventing workman's assembled in situ by the fixing object of locating stud 3, due to careless and inadvertent and barrel nut is anti-loaded.
Described barrel nut 1 epimere 101 makes epimere 101 parts 2 detain pitch generation mechanically deformation by the mode of 3 closing ins and forms auto-lock function, and this auto-lock function is conducive to increase this barrel nut assembly vibration performance.
A kind of barrel nut assembly of the utility model has stable mechanical performance, installation reliability high, can reduce in a large number due to the duplication of labour that caused by extraneous factor and improve the reliability of installing, having improved nut Fatigue Vibration performance by nut metal self-locking.
