Applications des accouplements cannelés

A spline coupling is a highly effective means of connecting 2 or more components. These types of couplings are very efficient, as they combine linear motion with rotation, and their efficiency makes them a desirable choice in numerous applications. Read on to learn more about the main characteristics and applications of spline couplings. You will also be able to determine the predicted operation and wear. You can easily design your own couplings by following the steps outlined below.

Conception optimale

L'accouplement cannelé joue un rôle important dans la transmission du couple. Il se compose d'un moyeu et d'un arbre dont les cannelures sont en contact et sans mouvement relatif. Du fait de leur liaison, leur vitesse angulaire est identique. Les cannelures peuvent être conçues avec n'importe quel profil minimisant le frottement. Le contact entre les cannelures entraîne une répartition inégale de la charge, qui se concentre sur une petite surface, pouvant déformer le moyeu.
La conception optimale des accouplements cannelés tient compte de plusieurs facteurs, notamment le poids, les caractéristiques des matériaux et les exigences de performance. Dans l'industrie aéronautique, le poids est un facteur de conception important. Les tableaux SAE et ANSI ne prennent pas en compte le poids lors du calcul des exigences de performance des accouplements cannelés. L'encombrement est un autre facteur critique. Les accouplements cannelés peuvent devoir être installés dans des espaces restreints ou être soumis à d'autres contraintes de configuration.
Optimal design of spline couplers may be characterized by an odd number of teeth. However, this is not always the case. If the external spline’s outer diameter exceeds a certain threshold, the optimal spline coupling model may not be an optimal choice for this application. To optimize a spline coupling for a specific application, the user may need to consider the sizing method that is most appropriate for their application.
Une fois la conception générée, l'étape suivante consiste à tester l'accouplement cannelé obtenu. Le système doit vérifier l'absence de contraintes de conception et valider sa faisabilité à l'aide des techniques de fabrication modernes. Le modèle d'accouplement cannelé résultant est ensuite exporté vers un outil d'optimisation pour une analyse plus approfondie. Cette méthode permet au concepteur de modifier facilement la conception d'un accouplement cannelé et d'en réduire le poids.
The spline coupling model 20 includes the major structural features of a spline coupling. A product model software program 10 stores default values for each of the spline coupling’s specifications. The resulting spline model is then calculated in accordance with the algorithm used in the present invention. The software allows the designer to enter the spline coupling’s radii, thickness, and orientation.

Caractéristiques

An important aspect of aero-engine splines is the load distribution among the teeth. The researchers have performed experimental tests and have analyzed the effect of lubrication conditions on the coupling behavior. Then, they devised a theoretical model using a Ruiz parameter to simulate the actual working conditions of spline couplings. This model explains the wear damage caused by the spline couplings by considering the influence of friction, misalignment, and other conditions that are relevant to the splines’ performance.
Pour concevoir un accouplement cannelé, l'utilisateur saisit d'abord les critères de dimensionnement des éléments porteurs, notamment la cannelure externe 40 du modèle d'accouplement cannelé 30. Il spécifie ensuite les exigences de performance relatives à la marge de couple, telles que la limite d'élasticité, le flambage plastique et le flambage par fluage. Le logiciel calcule alors automatiquement les dimensions et la configuration des éléments porteurs et de l'arbre. Ces spécifications sont ensuite intégrées au logiciel de modélisation 10 en tant que valeurs de spécification.
Les différentes configurations d'accouplements splines sont saisies sur l'écran 80 de l'interface graphique. Le logiciel 10 génère ensuite un modèle d'accouplement spline en enregistrant les valeurs par défaut de ces configurations. L'utilisateur peut alors manipuler ce modèle en modifiant ses différentes spécifications. Le résultat final est une conception assistée par ordinateur permettant aux concepteurs d'optimiser les accouplements splines en fonction de leurs performances et des spécifications de conception.
Le logiciel de modélisation des couplages splines évalue en continu la validité des modèles de couplage spline pour une application donnée. Par exemple, lorsqu'un utilisateur saisit une valeur de données correspondant à un signal de paramètre, le logiciel compare cette valeur à la valeur correspondante dans la base de connaissances. Si les valeurs sont hors spécifications, un message d'avertissement s'affiche. Une fois la comparaison terminée, le logiciel génère un rapport contenant les résultats.
Various spline coupling design factors include weight, material properties, and performance requirements. Weight is 1 of the most important design factors, particularly in the aeronautics field. ANSI and S.A.E. tables do not consider these factors when calculating the load characteristics of spline couplings. Other design requirements may also restrict the configuration of a spline coupling.

Applications

Spline couplings are a type of mechanical joint that connects 2 rotating shafts. Its 2 parts engage teeth that transfer load. Although splines are commonly over-dimensioned, they are still prone to fatigue and static behavior. These properties also make them prone to wear and tear. Therefore, proper design and selection are vital to minimize wear and tear on splines. There are many applications of spline couplings.
La conception d'un accouplement cannelé repose sur le diamètre de l'arbre à assembler. Ceci permet un espacement optimal des clavettes. Une méthode innovante de taillage par fraise-mère permet la réalisation de bases coniques sans interférence, et le pied des clavettes est concentrique à l'axe. Ces caractéristiques garantissent des cadences de production élevées. Les accouplements cannelés trouvent de nombreuses applications dans divers secteurs industriels. Pour en savoir plus, poursuivez votre lecture.
La méthodologie par éléments finis permet de prédire le taux d'usure des accouplements cannelés en intégrant l'évolution du coefficient de frottement. Cette méthode, qui permet de prédire l'usure par frottement à partir d'une géométrie simple de surface plane, a été calibrée à l'aide de données expérimentales. Le taux d'usure prédit est cohérent avec les données expérimentales. L'évolution du frottement dans les accouplements cannelés dépend de la géométrie des cannelures. Il est également crucial de prendre en compte les conditions de lubrification des cannelures.
Using a spline coupling reduces backlash and ensures proper alignment of mated components. The shaft’s splined tooth form transfers rotation from the splined shaft to the internal splined member, which may be a gear or other rotary device. A spline coupling’s root strength and torque requirements determine the type of spline coupling that should be used.
The spline root is usually flat and has a crown on 1 side. The crowned spline has a symmetrical crown at the centerline of the face-width of the spline. As the spline length decreases toward the ends, the teeth are becoming thinner. The tooth diameter is measured in pitch. This means that the male spline has a flat root and a crowned spline.

Prévisibilité

Spindle couplings are used in rotating machinery to connect 2 shafts. They are composed of 2 parts with teeth that engage each other and transfer load. Spline couplings are commonly over-dimensioned and are prone to static and fatigue behavior. Wear phenomena are also a common problem with splines. To address these issues, it is essential to understand the behavior and predictability of these couplings.
Dynamic behavior of spline-rotor couplings is often unclear, particularly if the system is not integrated with the rotor. For example, when a misalignment is not present, the main response frequency is 1 X-rotating speed. As the misalignment increases, the system starts to vibrate in complex ways. Furthermore, as the shaft orbits depart from the origin, the magnitudes of all the frequencies increase. Thus, research results are useful in determining proper design and troubleshooting of rotor systems.
The model of misaligned spline couplings can be obtained by analyzing the stress-compression relationships between 2 spline pairs. The meshing force model of splines is a function of the system mass, transmitting torque, and dynamic vibration displacement. This model holds when the dynamic vibration displacement is small. Besides, the CZPT stepping integration method is stable and has high efficiency.
La distribution du glissement dépend de l'état de lubrification, du coefficient de frottement et du nombre de cycles de charge. Les profondeurs d'usure prédites correspondent bien aux valeurs mesurées. Ces prédictions sont basées sur la distribution du glissement. La méthodologie prédit une usure accrue en conditions de lubrification légère, mais pas en cas de lubrification renforcée. L'état de lubrification et le coefficient de frottement sont les facteurs clés qui déterminent le comportement à l'usure des cannelures.
