The utility model discloses processing is simple, simple to operate, operation are reliable, and the locking back is locking effectual during the use, and the shockproof effect is good, has good corrosion resisting property simultaneously.
Description
Technical field
This utility model relates to a kind of nut, particularly relates to a kind of stop nut.
Background technology
Nut is to be threaded together the part for playing the role of fastening with bolt or screw rod; it is widely used in the multiple industries such as railway, bridge, electric power, automobile, petrochemical industry, boats and ships, Aero-Space, engineering mechanical device; during the long-time use of parts; nut is often occurred to loosen out of gear mesh phenomenon from bolt; cause connector to disintegrate to come off, cause great accident.Existing nut anti-looseness generally places pad between nut and bolt, utilizes the elastic force of pad to withstand nut.But pad shock resistance under high vibration environment is poor, it is more difficult to meet locking requirement, and screw-down torque is relatively big, brings inconvenience to the maintenance of various equipment.
Existing frequently-used anti-loose method has: 1, machinery is locking.The method is directly to limit secondary the relatively rotating of locking nut, dismounting inconvenience with locking nut retainer.As used pin of opening one's mouth, series winding steel wire and stop washer etc..Owing to locking nut retainer does not has pretightning force, locking nut pine when falling back on stop position locking retainer just can work, thus, this mode of locking nut is put into practice the most locking but is avoided withered and fallen.2, riveting is rushed locking, uses and rushes point, welding, the way such as bonding, make locking nut pair lose kinematic pair characteristic and be connected and become non-disconnectable linking after tightening.The defect of this mode is that tightening latch can only use once, and dismounting is the most difficult, it is necessary to damaging bolt pair can dismantle.3, rubbing locking, this locking mode of one being most widely used, this mode produces a kind of not with the normal pressure of external force change between locking nut pair, can stop locking nut pair frictional force in relative rotation producing one.This normal pressure can be through axially or simultaneously two completing to compressing locking nut pair.As used elastic washer, double nut, self-locking nut and inserts locking nut etc..4, construct locking, be application lock jack panel copy body structure, use right-and-left threaded locking mode.
At present, it is complicated generally to there is structure in the stop nut that above-mentioned conventional anti-loose method is made, and anti-loosing effect is poor, changes the problems such as trouble, anti seismic efficiency difference.
Utility model content
Utility model purpose: this utility model solves the problems referred to above, it is provided that a kind of stop nut with memorial alloy ring.
Technical scheme: a kind of stop nut with memorial alloy ring, including nut body and memorial alloy ring；Being provided with screwed hole in described nut body, described nut body is divided into the portion of screwing up and boss portion in the axial direction of described screwed hole, and described boss portion is positioned at the open side of described screwed hole；Offering retraction slot radially in described boss portion, described retraction slot is uniformly distributed in described boss portion；Being provided with restriction protrusion on the external diameter of described boss portion, described restriction protrusion is positioned at described screwed hole opening part；Described memorial alloy ring is that memory alloy material is made, and when reaching phase transition temperature, described memorial alloy ring shrinks deformation；Described memorial alloy ring set is located at outside described boss portion, in described restriction protrusion and described screw up between portion.
As a kind of preferred version of the present utility model, described retraction slot is 2-12 bar.
As a kind of preferred version of the present utility model, the material of described nut body is the one in carbon steel, rustless steel, titanium, titanium alloy.
As a kind of preferred version of the present utility model, described boss portion is ring taper.
As a kind of preferred version of the present utility model, described in the portion of screwing up be the one in triangle cylinder, square cylinder, hexagonal is quincunx cylinder, regular hexagon cylinder, octagon cylinder.
Beneficial effect: this utility model is compared with prior art, have an advantage in that: this utility model processing is simple, easy for installation, reliable, during use locking after locking effective, shockproof effect is good, material therefor has good decay resistance simultaneously, can be used on the fastening position that the environment such as boats and ships, chemical industry is harsh.Memorial alloy ring has good damping and amortization, can resist various frequency and the vibration of amplitude and not loosen, and can be widely applied to the field that engineering machinery, automobile, railway, bridge equifrequency are vibrated.And titanium or titanium alloy density proportion is low, intensity is high, nut anti-looseness is effective, can apply in fields such as Aero-Space.
