Description
1 TARIFF MECHANICAL SERVICE CYCLE RECORDED CONNECTION SYSTEM TECHNICAL FIELD The invention relates to bolts, nuts, studs, screws and similar threaded fasteners, and these fasteners. 5 mechanical records for tracking the usage and service history of components and It is related to instrumentation systems. The invention specifically applies to devices that can be disassembled and reused during maintenance, repair, or inspection operations. Verified disassembly and re-tightening service cycles of fasteners, external power a real 10 that records mechanically without needing a source or electronic memory. What distinguishes unwinding operations from other load and motion changes is that the same unwinding operation prevents it from being saved multiple times and has a predefined reuse limit. with service cycle memory connector systems that indicate to the user when the connection has been reached It is related. STATE OF THE ART 15 Today, bolts, nuts, studs, screws, and similar threaded fasteners are used in machinery, Automotive, aviation, rail, energy, pressure vessels, pipe fittings, lifting equipment, Parts in numerous technical fields, particularly mold systems and heavy industry. They are commonly used for connecting items to each other in a detachable manner. This type In connections, the fastener must be mounted with the appropriate tightening force, as well as the usage. 20 maintaining the reliability of the connection throughout the process and during maintenance operations. It is also important to be able to monitor the condition of the personnel. Especially periodic maintenance, In systems requiring part replacement, inspection, or repair, the same bolt, nut, or similar component should be used. The fastener can be disassembled and reassembled multiple times. Each disassembly and reassembly... During the re-tightening process, the fastener is subjected to axial load, friction, and 25° on the tooth surfaces. Mechanical effects occurring on contact surfaces through contact, squeezing, and loosening movements. It remains below this level. Therefore, in certain applications, it is important to consider how many times the connecting element can be removed or not removed. Tracking information about reuse, evaluating the connection's maintenance history. and determining whether the predetermined reuse limit has been reached It is important in terms of... 30 The service history of fasteners used in the field is directly related to the fastener itself. Determining this through the outside of a bolt or nut is often not possible. From its appearance, it appears that the component in question has never been disassembled before, or has been disassembled once and reassembled. 2 reliable confirmation that it has been installed or used in numerous maintenance cycles It is quite difficult. Service history maintenance records, user-maintained schedules or Tracking via external recording systems involves the connector itself and the service. the loss of the link between the past, the lack of records, or the transfer of the connecting element to another It may be insufficient in situations such as transferring data to a single point. 5 In the known state of the art, for specific parts of the problems listed above Washers indicate the tightening force or preload of the fastener, the connection indicators that determine its loosening, undergoing permanent shape change after squeezing. Mechanical markers and electronic measurement or recording systems have been developed. together, by determining the instantaneous tightness or looseness of the connection, connection 10 disassembly and re-tightening service cycles performed by the component in the past Recording them are different technical problems. The connection is currently insufficient. Knowing that it has a preload indicates how many services the connector in question has previously undergone. It alone does not prove that it has gone through the cycle. Another technical difficulty in mechanically recording the service cycle is the 15 on the link. Every change in load or movement that occurs constitutes an actual disassembly process. It is the failure to come. The connection settling, small gaps occurring on the connection surfaces. changes, thermal expansion and contraction, vibration, elastic relaxation or operation Load changes resulting from these conditions cause a decrease in the axial load of the connection. This is possible. Similarly, limited angular movements occurring in the connecting element 20 This does not always prove that the connection has actually been disconnected. Therefore, it is not merely a record dependent on axial load change or solely on the angular movement of the fastening element The mechanism allows the service cycle to be recorded even though no actual service operation has taken place. This can be the reason. Also, when loosening a fastener, the bolt or nut may need to be turned more than once. 25 Since it can be rotated, if the unwinding action is directly transferred to a mechanical counter There is a risk that the same disassembly operation may be recorded as multiple service cycles. This Therefore, it is essential to reliably track the usage history of the fastener. From this perspective, it's not just about perceiving movement or load changes, but about providing a real service. The separation of this cycle from other mechanical movements and the fact that a single disassembly operation is performed only once 30 Recording it is also important. A literature review conducted in the current state of the art also revealed that the fastener is suitable. Various mechanical washer systems for determining whether the clamping load has been reached. It is located. As a result of the research, patent number US5667346A was identified. In the document, it is stated that the appropriate preload is obtained in a connection formed with a bolt and nut. 35 3 A preload indicator washer for determination is described. The washer in question... The protrusions formed on it allow the compressive force applied during tightening of the connection to be absorbed. Due to its effect, it deforms towards the corresponding indentations, and the resulting geometric It is determined that the connection has reached the predicted compression level through the change. This The solution involves mechanically determining the tightening condition of the connection, however, 5 The service cycle consists of successive removal and retightening operations of the fastener. It does not present a mechanical memory structure that records such data. This patent, numbered US20060283260A1, is also encountered in the known state of the art. the document includes a reusable one that can show the preload applied to the fastener. The preload indicator washer is described. The system consists of a ring-shaped flexible inner element with 10 An external element and washer elements are used around this; applied The system can be reused after the force is removed and in the subsequent tightening operation. The aim is to re-represent the connection load. The solution discussed here. It provides a preload indicator that can be used in multiple squeezing operations, The total number of disassembly and reassembly operations performed on the fastener is 15. It does not create a service history that is recorded mechanically. Consequently, in the known technique, the preload or clamping condition of the fastening element to determine, detect, and identify any loosening in the fastener. It appears that there are various systems for displaying statuses to the user. However, it takes 20 days for a particular fastener to reach the required tightening condition. The actual unwinding processes that occur after verification, other loads and movements separating it from its changes, preventing the same solution operation from being counted multiple times, and Verified service cycles require an external power source or electronic memory. In terms of the technique being mechanically recorded on the fastener without being detected, It needs to be improved. 25 THE PURPOSE OF THE INVENTION The primary purpose of the invention is to produce bolts, nuts, studs and similar threaded fasteners. actual disassembly and re-tightening service performed during maintenance and repair processes their cycles, without the need for an external power source or electronic memory, reliable recording on a mechanical structure associated with the fastening element 30 The goal is to create a system of fasteners that provides this functionality. The purpose of the invention is to account for every decrease in load or every angular shift occurring in the connecting element. By preventing the movement from being considered as a service cycle, a true unwinding process can be avoided. The aim is to provide a structure that can distinguish mechanical movements from conventional ones. In this regard, the system... 4 It must verify that the connection has already reached a sufficient compression state, and only then... the fulfillment of the necessary mechanical conditions for the disconnection of the connection after the situation The aim is to create a service cycle record in this case. The other objective of the invention is to determine the first threshold force (F1) reached during the tightening of the connection. to prepare the system for service cycle recording; during the said setup process 5 to avoid recording any service cycles and during subsequent connection resolution Solving by reducing the axial load to a lower second threshold force (F2) level. the simultaneous occurrence of a predetermined minimum relative angular movement in that direction The goal is to identify a verified resolution event by searching. Thus, only the load... 10 erroneous service records that may result from reduction or angular movement alone The aim is to reduce it. Another objective of the invention is to determine the angular movement towards the solution and the axial load release condition. The goal is to provide a mechanical verification structure that operates independently of the order of occurrence. According to the mechanical system, the result is obtained when one of the conditions occurs before the other. Maintaining the verification status and service cycle record is only possible if the necessary conditions are met together. 15 It is intended to be implemented upon completion. Another objective of the invention is to extend the service cycle as a result of a single verified decoding process. to ensure that its memory advances by only one level and that the connector solves the same problem rotating it more than once during the process, changing its load, or the mechanism If it moves again, the same disassembly process will be performed as multiple service cycles (20). The goal is to mechanically prevent the recording. This blockage can only be removed when the connection is sufficiently restored. By bringing it to the compression state and then releasing it, a new compression-decompression cycle is performed for each new record. The aim is to complete the service cycle. Another purpose of the invention is to allow the user to record and verify service cycles. it can be tracked directly via the connection element and a predetermined maximum of 25 The visual indication that the connector needs to be replaced when the number of reuses is reached. and / or to ensure that the user is notified by a mechanical signal. Thus, the connection By reducing the reliance of the employee's service history on external maintenance records, reuse is possible. The aim is to enable direct monitoring of the status at the connection point. Another objective of the invention is to connect the main 30 of the service cycle recording mechanism. By separating it as much as possible from the axial load carrying path, the precision counter, latch, protecting the sliding and indexing components from high clamping loads and the system a freestanding module, a nut-integrated structure, or a bolt-integrated structure The aim is to ensure that it can be adapted to different connection applications.

DETAILED DESCRIPTION OF THE INVENTION The invention is a bolt that can be removed and reused during maintenance, repair or inspection operations. 5 Verified service cycles performed by nuts and similar fasteners It is related to a linkage system (1) for mechanical recording. The linkage system (1), In its basic application, it works in relation to a bolt (2) and / or nut (3) and connection It includes a logging module (4) which mechanically records the service history of the element. The registration module (4) measures the axial load 10 that occurs during tightening and loosening of the connection. the relative angular movement of the connecting element in the direction of loosening with its change will perceive it independently and provide a service if the aforementioned conditions occur together. It is configured to create a cycle record. Thus, any events occurring in the connection system... The incoming service is based solely on a change in load or only a limited angular movement. This prevents it from being recorded as a cycle. 15 The registration module (4) is prevented or restricted from rotating relative to the connection surface (24). a movable ring (6) that can rotate together with a fixed ring (5) and a bolt (2) or nut (3) It includes. The fixed ring (5) is mechanically connected to the connecting surface (24) with at least one By means of the fixing protrusion (25) the reference position relative to the connection surface (24) It protects. The movable ring (6) is secured by means of a bolt (2) or nut (3) 20 via the rotating carrier (26). It is related to rotation. Thanks to this structure, the connecting element the relative lag that occurs between the fixed ring (5) and the movable ring (6) during its resolution Angular motion can be determined mechanically. The registration module (4) also records the axial load that occurs during the tightening of the connection. It includes a load sensing element (7) that converts the change in load into mechanical motion. Load 25 The sensing element (7) is shaped depending on the axial load that increases with tightening of the connection. changing or displacing and setting the mechanical movement in question on the bolt (8) It transmits. The load sensing element (7) is an elastic spring element, disc depending on the application. a spring, ring-shaped elastic element, or similar mechanical device exhibiting controlled deformation It can be implemented in the form of elements. 30 During tightening of the connection, the axial load reaches a predetermined first threshold force (F1). When it reaches or exceeds the said value, the load sensing element (7) is generated As a result of the movement, the cocking bolt (8) is brought to the cocked position. The cocking bolt (8) is then... It is held in position by the locking latch (9). Reaching the first threshold force (F1) 8 This makes the registration module (4) ready for the determination of a new service cycle, The number of service cycles is not increased at this stage. The setting slide (8) moving to the set position also marks the end of the previous service cycle. Preparing the blocking element (16) that may have become active for a new service cycle This is provided by the blocking reset cam (29) associated with the movement of the setting bolt (8). It brings the blocking element (16) to the position that allows registration. Thus, the system For a new service cycle to be recorded, the connection must be restored to the first threshold force (F1). It needs to be squeezed that much. During the subsequent turning of the connection in the direction of unwinding, the movable ring (6), bolt (2) or when moving with the nut (3) the fixed ring (5) is 10 relative to the connection surface (24). It maintains its reference position. It occurs between the fixed ring (5) and the movable ring (6). The resulting relative rotational motion is transferred to the unwinding cam (11). The unwinding cam (11) compresses to confirm the relative movement towards the resolution direction rather than the movement in the other direction It is being structured. When the relative angular movement in the unwinding direction reaches the predetermined minimum angular value, 15 The unwinding cam (11) activates the verification pin (12). The verification pin (12) As a result of the movement, the angular memory slider (27) is brought to the verified position. Angular memory slider (27), mechanical regarding the occurrence of the necessary angular movement in the direction of decoding. the status remains the same until the other necessary condition for recording the service cycle is met. It protects. 20 This allows the necessary angular movement and axial load release during the disconnection process. If it occurs before the condition is met, the angular verification in question is not lost, and It is mechanically stored via the angular memory slider (27). As the connection continues to be untangled, the axial load on the connection increases. It is decreasing. The axial load is determined as lower than the first threshold force (F1) in the second 25 When the load sensing element reaches or falls below the threshold force (F2) (7) the position change it caused releases the load tracker (28) to the position This brings about a mechanical situation where the connection is relieved of sufficient load. It is confirmed. The release latch (10), the angular memory slider (27) and the load follower (28) together 30 It is related to the mechanical verification structure it creates. The setting of the release latch (10) In order to release the slide (8), both the necessary relative angular movement in the unwinding direction is required. The fact that the angular memory slider (27) has been verified and the axial load has been second thresholded 9 the load tracker (28) confirms that it has fallen to or below force (F2). It is required that only one of these two conditions is met for the service cycle to be interrupted. That is not sufficient for recording. Regardless of which condition occurs first. As such, when both conditions are present together, set up the release latch (10). It releases the slider (8). Thus, the registration module (4) is released with axial load relief. a study that mechanically verifies the relative angular motion in the resolution direction It has the following structure. The cocking bolt (8) returns after being released by the release latch (10). It moves in the initial direction under the influence of the return spring (23). The bolt (8) During the said backward movement, the advancement claw (13) is mechanically connected to the index wheel (14) 10 By interacting, it advances the index wheel (14) by only one step. The index wheel (14) a step progression, mechanically recording a verified service cycle It provides. The index wheel (14) returns to its previous record position by moving in the opposite direction. This is blocked by the lock (15). Thus, the recorded service cycle information is blocked by the external 15 mechanically without the need for a power source or electronic memory It is protected. After one step advancement of the index wheel (14), the blocking element (16) is in the active position. It is passing. The active position blocking element (16) continues the same unwinding process. This prevents the advancement claw (13) from advancing the index wheel (14) a second time. Thus 20 Turning the bolt (2) or nut (3) more than one turn in the same unscrewing operation, If the load changes or additional movement occurs in the mechanism, the single unit in question... The disassembly process is not recorded as multiple service cycles. Blocking element (16), retightening of the connection and return to the first threshold force (F1). If reached, the location that allows recording by the blockage reset cam (29) is 25 This is done so that a connection can be established first in order to record each new service cycle. reaching a sufficient compression state, followed by a verified release process. This is necessary. This structure ensures that only one record is created in each service cycle. The index wheel (14) allows the user to track the number of registered service cycles. It is mechanically related to the indicator disc (18). The position of the indicator disc (18) is 30 The recorded service cycles are visible from the outside through the display window (17). It can be presented to the user through lines, symbols, or similar forms of representation. Replacement when the predetermined maximum number of service cycles for the fastener is reached. The indicator (19) becomes visible or mechanically perceptible. Thus The user directly notices that the connector has reached its defined reuse limit. It can be determined via the connection point. The system directly detects the connection element. Instead of measuring metal fatigue, it records verified service cycles and previously 5 This indicates that the defined service cycle limit has been reached. In the application of the independent registration module (4), the registered service history is transferred to another bolt. Matching groove (20) on bolt (2) to prevent transfer, in the registration module (4) is at least one matching channel mechanically associated with the said matching channel (20). The matching tab (21) can be found. The matching tab (21) is bolt (2) 10 of the registration module (4). while ensuring it is held in place, it allows the necessary relative movement for determining the service cycle. It can be arranged in such a way as to give. Separation of the registration module (4) from the bolt (2). In the event that the matching nail (21) is deformed, broken or shows a visible mark by ensuring that the service history is created without leaving a trace on another connection element. The transfer can be prevented. 15 The main axial clamping load generated during connection ensures the precision of the registration mechanism. as independently as possible from its components via the load carrying ring (30) It is transferred. The locking bolt (8), latches, index wheel (14), advancement tab (13), locking mechanism element (16) and related movable components are in the mechanism housing (31), main clamping It can be positioned to be protected from the direct impact of the load. Load sensing 20 element (7) can carry the entire axial load of the connection or a predetermined amount of load. It can be configured to detect this section. The allowable stroke of the load sensing element (7) and associated moving parts It can be limited by means of a limiter (22). Thus, overtightening or high load Under these conditions, the deviation of the mechanism from its intended range of motion can be reduced. Record 25 The mechanism housing (31) of the module (4) can be protected from dirt, moisture or foreign matter from the outside environment. with a protective cover (32) to reduce the amount of substances reaching the mechanism It can be switched off. In one application of the invention, the registration module (4) is connected to the surface with a bolt (2) or nut (3). (24) It can be created as an independent module located between them. Another 30 In practice, the registration module (4) is integrated into the body of the nut (3). It can be adjusted. In this application, the fixed ring (5) is angular relative to the connection surface (24). Relative motion during the solution of the movable structure associated with the nut (3) while creating a reference. It creates. 11 In another application, the registration module (4) is integrated into the head of the bolt (2). It can be created. In this application, the fixed ring (5) is referenced to the connection surface (24). to create and the relative angular motion recording module (4) formed by the rotation of the bolt (2) It is processed mechanically by [the system / organization]. This allows for the verification of service cycles and... The same mechanical working principle applies to recording; independent module, integrated into the nut 5 It can be implemented in module or bolt-integrated module forms. The first threshold force (F1), the second threshold force (F2), and the minimum relative angular force required in the resolution direction. movement; dimensions of the fastener, application area, target tightening load and anticipated service These thresholds can be determined depending on the conditions. These thresholds are determined by the load sensing element (7) mechanical properties, geometry of the unwinding cam (11), positions of the ratchet and bolts and stroke 10 It can be adjusted via mechanical parameters such as the position of the limiter (22). Thanks to this structure, the connection system (1) can reduce only a load or only an angular shift. Instead of considering the movement as a service cycle, sufficient tightening condition beforehand the occurrence, followed by the load and angular motion conditions relating to the actual unwinding process. verification together and only one mechanical record for each verified decoding operation 15 It enables its creation. The scope of protection in this application is defined in the claims section and is explicitly stated above. The examples given cannot be limited to those that a technically skilled person demonstrates in the invention. the innovation introduced can be created by using similar structures and / or this It is clear that the structure can be applied to other areas with similar purposes using the relevant technique. 20 Therefore, such structures foster innovation and, in particular, surpassing the known state of technology.
