Abstract
The utility model discloses a high temperature resistant anti-vibration MJ plate nut, which structurally comprises a plate nut (1) made of A286 materials; and a molybdenum disulfide layer is arranged on threads of the plate nut (1). The plate nut comprises a cylindrical nut (2) and a carrier plate (3); threads of the cylindrical nut (2) are metric system aerospace threads (4); a check closed opening (5) is arranged at the ends of the threads; the carrier plate (3) is a single-lug carrier plate or a double-lug carrier plate; and a rivet hole (6) is arranged on the carrier plate (3). The high temperature resistant anti-vibration MJ plate nut has higher yield strength and long-time and creep strength, has better processing plasticity and satisfaction welding performance, is capable of preventing bonding with a matching bolt, or even damaging to threads of the matching bolt, and capable of meeting requirements of long-term work under high temperature of 600 DEG C to 650 DEG C and high vibration, and has long service life.
Description
Technical field
The utility model relates to a kind of plate nut, particularly relates to a kind of MJ plate nut of high temperature resistant anti-vibration.
Background technique
Used nut on the aeroengine is because long-term work under 600～650 ℃ high temperature, and has very vibration, so very high to the requirement of nut.Present all nuts because yield strength and lasting, creep strength is relatively poor, causes with supporting bolt sticking deadly through regular meeting, even with the thread damage of supporting bolt, can not well satisfy the requirement of long-term work under 600～650 ℃ of high temperature and judder.
Summary of the invention
The purpose of this utility model is, a kind of MJ plate nut of high temperature resistant anti-vibration is provided.Have higher yield strength and lasting, creep strength, and have working plasticity and satisfied welding performance preferably.And can prevent and supporting bolt bonding, even damage the screw thread of supporting bolt, can satisfy the requirement of long-term work under 600～650 ℃ high temperature and strong vibration, long service life.
The technical solution of the utility model: a kind of MJ plate nut of high temperature resistant anti-vibration, comprise the plate nut made from the A286 material, the screw thread of plate nut is provided with the curing molybdenum layer.
In the MJ plate nut of aforesaid high temperature resistant anti-vibration, described plate nut comprises cylindrical nut and supporting plate, and the screw thread of cylindrical nut is a metric system Aero-Space screw threads, and the end of screw thread is provided with locking closing in; Supporting plate is monaural supporting plate or ears supporting plate, and supporting plate is provided with rivet hole.
In the MJ plate nut of aforesaid high temperature resistant anti-vibration, described ears supporting plate is straight line ears supporting plate or dihedral ears supporting plate.
In the MJ plate nut of aforesaid high temperature resistant anti-vibration, described straight line ears supporting plate is rhombus or double calabash shape.
Compared with prior art, plate nut of the present utility model is made with the A286 material, and the A286 material is the Fe-25Ni-15Cr based high-temperature alloy, adds molybdenum, titanium, aluminium, vanadium and trace B multiple strengthening.Under 600～650 ℃, have high yield strength and lasting, creep strength, and have working plasticity and satisfied welding performance preferably.Be subjected to product structure and material behavior, this product material is an A286 refractory alloy silk material, can upset by hot working and make parison spare, and the employing machine adds the processing method with punching press.In order to satisfy fatigue resistance, satisfy the usage requirement of product, its screw thread is selected the MJ screw thread.By the cylindrical end certain distance is carried out threading path to closing in,, play good locking interconnect function simultaneously to produce self-locking after satisfied and the supporting bolts assemblies.Through a large amount of verification experimental verifications; non-caked in order to better meet in the product assembling simultaneously with supporting bolt; even it is sticking dead with supporting bolt in assembling; avoid supporting bolt is destroyed; taking that self-locking nut is carried out molybdenum disulfide applies; this problem of fine inhibition, and have good lubricated and corrosion-resistant protective action.Material is high temperature resistant in addition, so the successful development of this product has solved the work of aeroengine long term high temperature, the fatigue resistance height stands the upper frequency vibration, plays the locking interconnect function of good self-locking.Simple installation, long service life.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment.The utility model as shown in Figures 1 to 4.A kind of MJ plate nut of high temperature resistant anti-vibration, formation comprises the plate nut made from the A286 material 1, the screw thread of plate nut 1 is provided with the curing molybdenum layer.Described plate nut comprises cylindrical nut 2 and supporting plate 3, and the screw thread of cylindrical nut 2 is that metric system Aero-Space screw thread 4(is the MJ screw thread), the end of screw thread is provided with locking closing in 5; Supporting plate 3 is monaural supporting plate or ears supporting plate, and supporting plate 3 is provided with rivet hole 6.Described ears supporting plate is straight line ears supporting plate or dihedral ears supporting plate.Described straight line ears supporting plate is rhombus or double calabash shape.
Application example of the present utility model as shown in Figure 5, the end that bolt 10 thread sizes are short is screwed into matrix 9 and tightens, fastener 8 bolt 10 of packing into, bolt 10 the other ends of again plate nut 1 being packed into are screwed into place, be that benchmark is joined brill matrix riveted holes with the rivet hole on the utility model 6 then, with plate nut 1 usefulness rivet 7 and matrix 9 riveted joints.It can not freely be rotated, and the function that can outside clamping force or compressive force, provide anti-spline to a certain degree to move back on the screw thread that matches, thereby reach the purpose of self-locking.Because the end of screw thread is provided with locking closing in 5, can play locking effect; Owing on screw thread, be provided with the curing molybdenum layer, can prevent nut and bolt bonding, can not damage bolt, also can play lubricated and corrosion-resistant protective action.Test the aeroengine high temperature load part requirement that can satisfy long-term work under 600～650 ℃ of temperature fully by installation, solved the shatter-proof and fine locking a kind of high temperature plate nut special fastener of connection that play of energy of high temperature.
