The Tubular\u00a0screw conveyors<\/strong>\u00a0have a wide range of applications in powder and granular material handling. Depending on the material being transported, different types of conveyors and feeders can be selected, for example: concrete products (cement, fly ash, filler dust, dust), bituminous products (hot and cold process dust), building ready-mix materials (Dried lime, sand, cement, fillers), glass technology (limestone, soda ash, sand, etc.), foundry (sand, bentonite), etc.<\/p>\n \u00a0<\/p>\n \u00a0<\/p>\n Structure size:<\/strong><\/strong> \u00a0<\/p>\n Tubular\u00a0screw conveyor has the following advantages:<\/strong><\/strong> \n \n <\/p>\n \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\u00a0<\/p>\n \n <\/p>\n \n \n \n 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. L'accouplement cannel\u00e9 joue un r\u00f4le 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 \u00eatre con\u00e7ues avec n'importe quel profil minimisant le frottement. Le contact entre les cannelures entra\u00eene une r\u00e9partition in\u00e9gale de la charge, qui se concentre sur une petite surface, pouvant d\u00e9former le moyeu. Un aspect important des cannelures de moteurs a\u00e9ronautiques r\u00e9side dans la r\u00e9partition de la charge entre les dents. Les chercheurs ont men\u00e9 des essais exp\u00e9rimentaux et analys\u00e9 l'influence des conditions de lubrification sur le comportement de l'accouplement. Ils ont ensuite \u00e9labor\u00e9 un mod\u00e8le th\u00e9orique, bas\u00e9 sur le param\u00e8tre de Ruiz, afin de simuler les conditions de fonctionnement r\u00e9elles des accouplements cannel\u00e9s. Ce mod\u00e8le explique l'usure caus\u00e9e par ces accouplements en prenant en compte l'influence du frottement, du d\u00e9faut d'alignement et d'autres facteurs affectant les performances des cannelures. 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. 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.

<\/p>\nConception optimale<\/h2>\n
La conception optimale des accouplements cannel\u00e9s tient compte de plusieurs facteurs, notamment le poids, les caract\u00e9ristiques des mat\u00e9riaux et les exigences de performance. Dans l'industrie a\u00e9ronautique, 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 cannel\u00e9s. L'encombrement est un autre facteur critique. Les accouplements cannel\u00e9s peuvent devoir \u00eatre install\u00e9s dans des espaces restreints ou \u00eatre soumis \u00e0 d'autres contraintes de configuration.
La conception optimale des accouplements cannel\u00e9s peut se caract\u00e9riser par un nombre impair de dents. Cependant, ce n'est pas toujours le cas. Si le diam\u00e8tre ext\u00e9rieur de la cannelure d\u00e9passe un certain seuil, le mod\u00e8le d'accouplement cannel\u00e9 optimal peut ne pas convenir \u00e0 l'application. Pour optimiser un accouplement cannel\u00e9 pour une application sp\u00e9cifique, l'utilisateur devra peut-\u00eatre choisir la m\u00e9thode de dimensionnement la plus appropri\u00e9e.
Une fois la conception g\u00e9n\u00e9r\u00e9e, l'\u00e9tape suivante consiste \u00e0 tester l'accouplement cannel\u00e9 obtenu. Le syst\u00e8me doit v\u00e9rifier l'absence de contraintes de conception et valider sa faisabilit\u00e9 \u00e0 l'aide des techniques de fabrication modernes. Le mod\u00e8le d'accouplement cannel\u00e9 r\u00e9sultant est ensuite export\u00e9 vers un outil d'optimisation pour une analyse plus approfondie. Cette m\u00e9thode permet au concepteur de modifier facilement la conception d'un accouplement cannel\u00e9 et d'en r\u00e9duire le poids.
Le mod\u00e8le d'accouplement cannel\u00e9 20 comprend les principales caract\u00e9ristiques structurelles d'un accouplement cannel\u00e9. Un logiciel de mod\u00e9lisation de produit 10 stocke les valeurs par d\u00e9faut de chaque sp\u00e9cification de l'accouplement. Le mod\u00e8le de cannelure r\u00e9sultant est ensuite calcul\u00e9 conform\u00e9ment \u00e0 l'algorithme utilis\u00e9 dans la pr\u00e9sente invention. Le logiciel permet au concepteur de saisir les rayons, l'\u00e9paisseur et l'orientation de l'accouplement.![\"arbre](\"https:\/\/img.hzpt.com\/img\/spline_shaft\/C_splineshaft_3.webp\")
<\/p>\nCaract\u00e9ristiques<\/h2>\n
Pour concevoir un accouplement cannel\u00e9, l'utilisateur saisit d'abord les crit\u00e8res de dimensionnement des \u00e9l\u00e9ments porteurs, notamment la cannelure externe 40 du mod\u00e8le d'accouplement cannel\u00e9 30. Il sp\u00e9cifie ensuite les exigences de performance relatives \u00e0 la marge de couple, telles que la limite d'\u00e9lasticit\u00e9, le flambage plastique et le flambage par fluage. Le logiciel calcule alors automatiquement les dimensions et la configuration des \u00e9l\u00e9ments porteurs et de l'arbre. Ces sp\u00e9cifications sont ensuite int\u00e9gr\u00e9es au logiciel de mod\u00e9lisation 10 en tant que valeurs de sp\u00e9cification.
Les diff\u00e9rentes configurations d'accouplements splines sont saisies sur l'\u00e9cran 80 de l'interface graphique. Le logiciel 10 g\u00e9n\u00e8re ensuite un mod\u00e8le d'accouplement spline en enregistrant les valeurs par d\u00e9faut de ces configurations. L'utilisateur peut alors manipuler ce mod\u00e8le en modifiant ses diff\u00e9rentes sp\u00e9cifications. Le r\u00e9sultat final est une conception assist\u00e9e par ordinateur permettant aux concepteurs d'optimiser les accouplements splines en fonction de leurs performances et des sp\u00e9cifications de conception.
Le logiciel de mod\u00e9lisation des couplages splines \u00e9value en continu la validit\u00e9 des mod\u00e8les de couplage spline pour une application donn\u00e9e. Par exemple, lorsqu'un utilisateur saisit une valeur de donn\u00e9es correspondant \u00e0 un signal de param\u00e8tre, le logiciel compare cette valeur \u00e0 la valeur correspondante dans la base de connaissances. Si les valeurs sont hors sp\u00e9cifications, un message d'avertissement s'affiche. Une fois la comparaison termin\u00e9e, le logiciel g\u00e9n\u00e8re un rapport contenant les r\u00e9sultats.
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.<\/p>\nApplications<\/h2>\n
La conception d'un accouplement cannel\u00e9 repose sur le diam\u00e8tre de l'arbre \u00e0 assembler. Ceci permet un espacement optimal des clavettes. Une m\u00e9thode innovante de taillage par fraise-m\u00e8re permet la r\u00e9alisation de bases coniques sans interf\u00e9rence, et le pied des clavettes est concentrique \u00e0 l'axe. Ces caract\u00e9ristiques garantissent des cadences de production \u00e9lev\u00e9es. Les accouplements cannel\u00e9s trouvent de nombreuses applications dans divers secteurs industriels. Pour en savoir plus, poursuivez votre lecture.
La m\u00e9thodologie par \u00e9l\u00e9ments finis permet de pr\u00e9dire le taux d'usure des accouplements cannel\u00e9s en int\u00e9grant l'\u00e9volution du coefficient de frottement. Cette m\u00e9thode, qui permet de pr\u00e9dire l'usure par frottement \u00e0 partir d'une g\u00e9om\u00e9trie simple de surface plane, a \u00e9t\u00e9 calibr\u00e9e \u00e0 l'aide de donn\u00e9es exp\u00e9rimentales. Le taux d'usure pr\u00e9dit est coh\u00e9rent avec les donn\u00e9es exp\u00e9rimentales. L'\u00e9volution du frottement dans les accouplements cannel\u00e9s d\u00e9pend de la g\u00e9om\u00e9trie des cannelures. Il est \u00e9galement crucial de prendre en compte les conditions de lubrification des cannelures.
L'utilisation d'un accouplement cannel\u00e9 r\u00e9duit le jeu et assure un alignement pr\u00e9cis des composants assembl\u00e9s. La cannelure de l'arbre transmet la rotation de l'arbre cannel\u00e9 \u00e0 l'\u00e9l\u00e9ment cannel\u00e9 interne, qui peut \u00eatre un engrenage ou un autre dispositif rotatif. La r\u00e9sistance \u00e0 la racine et le couple requis pour l'accouplement cannel\u00e9 d\u00e9terminent le type d'accouplement \u00e0 utiliser.
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.![\"arbre](\"https:\/\/img.hzpt.com\/img\/spline_shaft\/B_splineshaft_3.webp\")
<\/p>\nPr\u00e9visibilit\u00e9<\/h2>\n
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 d\u00e9pend de l'\u00e9tat de lubrification, du coefficient de frottement et du nombre de cycles de charge. Les profondeurs d'usure pr\u00e9dites correspondent bien aux valeurs mesur\u00e9es. Ces pr\u00e9dictions sont bas\u00e9es sur la distribution du glissement. La m\u00e9thodologie pr\u00e9dit une usure accrue en conditions de lubrification l\u00e9g\u00e8re, mais pas en cas de lubrification renforc\u00e9e. L'\u00e9tat de lubrification et le coefficient de frottement sont les facteurs cl\u00e9s qui d\u00e9terminent le comportement \u00e0 l'usure des cannelures.<\/p>\n![\"China](\"https:\/\/img.hzpt.com\/img\/spline_shaft\/spline_shaft_l1.webp\")
