Description

Anti-rotation sleeve, rotation stop limit component, fastening connection component and structure, rotation stop structure

Technical field:

The invention relates to a fastening connection technology of a thread pair mechanically coupling two or more objects; in particular, a mechanical static connection of a crankshaft linkage mechanism, a track structure, an aircraft, a ship, a device, an aerospace equipment, Anti-rotation sleeves, anti-rotation limit components, tight parts of mechanical parts on key parts of aircraft equipment, spacecraft, rockets, engines, nuclear reaction equipment, trains, high-speed rail, railroad tracks, steel structures, steel bridges, automobiles, etc. Solid connection components and structures, and anti-rotation structures, these mechanical parts are particularly harsh in use environment such as large vibration, high temperature environment, large load, etc., and the connection reliability of the mechanical connection of the thread pair is particularly high.

Background technique

Threaded sub-mechanical static joints between objects have some bolts broken at key parts, safety problems caused by failure of threaded connections and safety accidents, which are often encountered in the world, and are a common problem faced by technicians in the field. Solve the problem that has not been solved. Small bolts, large accidents, and frequent major accidents due to bolt breakage, such as the collapse of the connecting rod bolts of the engine of the automobile; the accident of 1 death and 4 injuries caused by the break of the bolts of Harbin tower crane on April 18, 2009; Taiwan's media reported that the No. 1 reactor of the No. 2 Plant of the Nuclear Power Plant detected 7 anchor bolt breaks and damages that may cause nuclear safety accidents; the guidance of the No. 5 cockpit support system occurred at 16:45 on June 29, 2012 Fatigue fracture of stud bolts caused a serious safety accident in which 6 people were killed and 10 people were injured in the "Space Trek" entertainment project in OCT East Shenzhen. As a representative manufacturer of high-end vehicles, the BMW engine was broken due to technical problems that could not solve the screw break. The loss of power and flameout at the moment of the break led to the recall of 230,000 vehicles (BMW (China) Automobile Trading Co., Ltd., BMW Brilliance Automotive Co., Ltd. decided to recall 230,000 vehicles since June 18, 2014), and the manufacturer suffered huge economic losses. And the loss of goodwill, more serious is the safety of the owner's life and property. Although in many cases, especially in the state of vibration, it is often necessary to regularly repair and reinforce the already tightened fastening joints to prevent the safety of accidental loosening or even looseness of the thread pair. There are many security incidents caused by the failure of the connection, and the examples are numerous.

The reliability of the threaded connection is ensured by the self-locking of the friction of the thread pair and the friction between the contact faces of the thread pair. In general, the connecting thread has a certain self-locking property and does not automatically loosen under static load conditions. However, due to the working conditions of the connection, there are inevitably impacts, vibrations, and load changes. Under these conditions, the friction between the pairs of threads will disappear or decrease instantaneously; at the same time, in the case of high temperature or temperature changes, the material will creep and stress relaxation, and the friction will be reduced. Under multiple actions, the threaded connection is gradually released.

The main reason for the failure of the threaded connection is that the thread is loose due to the reduction of the pre-tightening force. Therefore, the essence of the threaded connection is to prevent the reverse rotation of the thread pair (that is, the reverse between the threaded hole and the external threaded portion). Such as the reverse between the bolt and the nut.

The existing mechanical mechanical anti-loosening methods mainly include mechanical anti-loose methods such as a split pin, a stop pad and a string wire rope. Many of the aircraft are now also using the anti-loose method of the series wire rope.

In order to prevent loose thread connections, people have been working tirelessly.

U.S. Patent No. U.S. Patent No. 1,755,807, filed on Apr. 6, 1 s, filed on Apr. . The lock nut is provided with a threaded through hole and an internal gear-shaped rotation stop hole communicating therewith, and the minimum hole diameter of the rotation stop hole is larger than the diameter of the threaded through hole. The rotation preventing sleeve is provided with a rotation preventing through hole, and the outer circumference of the rotation preventing sleeve is an outer gear shape, and a rotation preventing strip is arranged on the wall of the rotation preventing through hole, and a rotation preventing groove is matched with the rotation preventing strip on the screw. The outer gear-shaped outer circumference of the anti-rotation sleeve and the gear-shaped hole wall of the lock nut rotation-stop hole cooperate with the constraint lock nut to rotate relative to the rotation sleeve, and the rotation sleeve of the rotation sleeve is inserted into the rotation groove of the screw to restrain the screw relative to the rotation sleeve Rotating, so the screw and the lock nut are mounted non-rotatably. In this patent, since the rotation preventing sleeve is completely accommodated in the rotation preventing hole of the lock nut, the rotation preventing sleeve is difficult to be taken out from the rotation preventing hole of the locking nut; and during the use of the screw and the nut, due to the rotation stop The sleeve, the screw and the nut are rusted, the dust enters between the rotation sleeve and the screw and the nut, and the mutual penetration of the rotation sleeve and the screw and the nut causes a large bite force between the rotation sleeve and the screw nut, thereby causing the rotation. The sleeve cannot be removed from between the screw and the nut. If the sleeve is difficult or impossible to remove from between the screw and the nut, it is difficult or impossible to separate the nut from the screw, thus losing the use of the threaded pair for the most basic purpose of easily separating the screw and the nut. Therefore, this screw and nut structure is of little use value.

Patent No. ZL201510198765.5, application publication number is CN 104819197A, application date is April 24, 2015, and publication date is August 6, 2015. The anti-loose nut connection structure includes connecting parts and Through the screw of the connecting piece, the screw on the screw is fastened to the connecting piece, the outer side of the nut is sleeved with a anti-loose ferrule, and the anti-rotation structure between the anti-rotation ferrule and the connecting piece is provided, and the anti-rotation structure includes a corresponding connector The sinking groove provided by the nut is arranged in the sinking groove after the nut is screwed, and the outer ring of the anti-loose ferrule is provided with a chuck, and the inner side wall of the sinking groove is provided with a card slot for the chuck to be inserted; the height of the anti-loose ferrule is less than Shen The height of the groove, the anti-loose ferrule and the nut and the sink are an interference fit. The anti-loose nut connecting structure of the invention has a anti-rotation ferrule and a anti-rotation structure between the anti-loose ferrule and the connecting member, and the inner ring of the anti-loose ferrule is a regular hexagonal structure matched with the nut, preventing The inner ring of the loose ferrule and the nut cannot rotate relative to each other, and the anti-rotation structure prevents the anti-loose ferrule from rotating relative to the connecting member, thereby preventing the nut from loosening after being fastened. The anti-loose nut connecting structure realizes the prevention of the looseness of the nut, but on the one hand, since the height of the anti-loose ferrule is smaller than the height of the sinking groove, and the anti-loose ferrule is in an interference fit with the nut and the sinking groove, the disassembly prevention When loosening the nut connection structure, the anti-loose and anti-loose ferrule cannot be taken out from the sinking groove, and the anti-loose and anti-loose ferrule cannot be taken out, so that the nut and the screw cannot be separated, so that the use of the threaded pair connection is lost. The most basic use of the separation of the screw and the nut, and thus the structure does not make any sense; on the other hand, the inner side wall of the sinker is provided with a card slot for the chuck to be inserted, and the card slot structure cannot be machined. If it is not molded with the connected parts in advance, it needs to be processed by electric sparks and the like, so the use cost is particularly high; and if the screw is not stopped, the screw will rotate relative to the lock nut, only the nut is stopped. There is no practical significance in turning. The above various reasons will make those skilled in the art believe that the technical solution of the invention has no use value, and greatly hinders the enthusiasm of those skilled in the art to improve the technical solution of the patent.

In the invention patent of the patent number ZL97112246.6, the publication date is 97112246.6, a lock nut is disclosed, which comprises a tool mounting portion and an annular protrusion projecting upwardly coaxially therewith, with a threaded hole penetrating therethrough. This kind of locknut is the HardLock nut, which is the only loose nut in the world. It is the technology that has been developed by the president of Hadlock Industrial Co., Ltd. for nearly 20 years through continuous technical improvement. The results are now more widely used on high-speed rail. When the high-speed rail is in operation, the trains and rails at high speed are constantly in contact, and the vibration generated is very large. The general screws will be shaken and shaken in this vibration. If you don't want to be shocked, you need the screws and nut to get into the buckle, never loose. This requirement seems simple, but it is not easy to satisfy it. The high-speed rail represents China's creation, but it uses Japanese nuts. Therefore, some media have issued a sigh that looks like a gap between Chinese manufacturing and Japanese manufacturing. However, this nut manufacturing process is very complicated, and the manufacturing precision is extremely high. Now, there are product drawings and products. Without the unique technology and know-how of Hardlock, it cannot be manufactured, so it is expensive, at least one. Dozens of dollars; this kind of nut can not be completely loose, but the anti-loose effect in the existing locknut is very good; this nut can not be used after repeated use for dozens of times.

Patent No. ZL201520399393.8 discloses a self-tightening nut and a bolt fastener. The fastener includes a self-tightening nut body, a self-tightening washer and a common bolt; the self-tightening nut body is in contact with the self-tightening washer The surface is a smooth transition spiral surface; the self-tightening nut body is screwed with the common bolt; the bolt fastener includes a self-tightening bolt, a self-tightening washer and a common nut; the ordinary nut is screwed with the self-tightening bolt. The self-tightening nut and the bolt fastener adopt a self-tightening principle, and a self-tightening structure is arranged on the nut or the bolt to make the self-tightening effect after the locking, so that the nut is no longer displaced or loosened. This kind of self-nut, also known as self-tightening nut and never loose nut, and claims that its anti-loose ability exceeds the hardlock nut, has been reported in CCTV. Since this nut is not widely used, its anti-loosening effect cannot be judged.

In the utility model patent with the publication number CN201934467U and the publication date of August 17, 2011, a front-end single-thread spiral rear double-line anchoring screw is disclosed, which mainly comprises a screw, and the screw has a self-tapping thread and a screw tail. The connecting end is provided with a connecting structural member, the connecting structural member is a hexagonal head, the outer hexagon head is provided with a gasket, and the bottom of the gasket is provided with a locking tooth. In the utility model, only a screw structure is disclosed, and all the structures described are part of the screw structure. From the point of view of the figure and the words on the outer hexagonal head, it can be understood without any objection. The gasket is a part of the screw, so there is no through-hole which is provided with the hexagonal head on the gasket. The gasket is installed outside the outer hexagonal head, and the gasket and the screw are two separate members. Since the gasket is a part of the screw, during the screwing process of the screw, the anti-loose teeth on the gasket and the gasket also rotate with the screw, so that although the anti-loose teeth are provided on the gasket, the anti-loose teeth are embedded. The connected object is not only embedded in the axially connected object, but in the process of rotation, the axial and circumferential displacements are embedded in the connected object, so that the anti-loose teeth will be connected to the connected object during the rotation of the screw. The surface forms a circumferential groove that is shallower and deeper in the direction in which the screw is screwed. The circumferential groove on the one hand destroys the appearance of the connected object; on the other hand, the insertion force of the anti-loose tooth and the connected object is greatly reduced, and it can be said that the anti-loose effect of the anti-loose tooth on the screw is very limited; In particular, due to the presence of the embedded teeth, it is difficult for the screws to lock the connected objects. Therefore, the locking teeth of the screw of this structure can not play the role of relaxation, and the screw of this structure has no use value.

In the U.S. Patent No. US Pat. No. 1,755,807, filed on Apr. 6, 1 s., the disclosure of the disclosure of the disclosure of the patent application No. s. In the Chinese invention patent on April 24, the technical solution of the rotation sleeve to limit the rotation of the nut was again proposed. After eighty-six years, it was not solved that the bolt and nut could be loosened or the sleeve can be locked with the sleeve. The bolts and nuts are loosened, and the technical problem of removing the bolts and nuts by removing the rotation sleeve from the rotation hole is convenient, fast and reliable. The existing hardlock nut and self-tightening nut which are considered to have good anti-loose effect are not used to prevent the nut from rotating by using the anti-rotation sleeve to prevent the nut from rotating. As soon as a century has passed, the nut has not been prevented from rotating by using the anti-rotation sleeve. To realize the technical application of the bolt and nut to prevent loosening; it can be seen that although people use the anti-rotation sleeve to prevent the nut from rotating to achieve the bolt and nut, the bolt and nut are difficult or The technical misunderstanding that cannot be disassembled forms a technique of using the anti-rotation sleeve to prevent the rotation of the nut to realize the looseness of the bolt and nut. This prevents the skilled person from improving the use of the anti-rotation sleeve to prevent the nut from rotating to realize the bolt and nut. The enthusiasm of the anti-loose technical solution.

In the above prior art fastening connection structure, it is necessary to place the rotation preventing sleeve in the rotation preventing hole to restrain the lock nut from reversing with respect to the screw. The disadvantage is that if the rotation preventing sleeve is completely accommodated in the rotation preventing hole, if the removal structure for taking out the rotation preventing sleeve from the rotation preventing hole is not obtained, the rotation preventing sleeve is difficult to be taken out from the rotation preventing hole; The rotation hole of the body is matched with the rotation preventing sleeve, or a rotation preventing member which is non-rotatably mounted with the attachment body is required, and the rotation preventing hole which cooperates with the outer circumference of the rotation preventing sleeve is processed on the rotation preventing member, and the cost is high.
