Structure and Principle<\/p>\n
This refiner is made up of main body, coupling and feed gear, etc.<\/p>\n
1.Main body<\/strong><\/p>\n The refiner has 2 CZPT sections. By the inclination angle of abrasion pattern, 4 CZPT plates are fixed, 2 left and 2 right. Two left plates are fixed on inner wall of machine shell and inside of rotating disc and 2 right plates are fixed on outside of rotating disc and moving pedestal, forming 2 CZPT sections (see drawing for installation instruction). Stock is conveyed to CZPT section through inlet pipe. After beating and refining, pumped out from the CZPT section and flows into shell, at last discharged from outlet pipe.<\/p>\n There are 2 bearings on the main shaft and fixed by bearing pedestal and connected to motor via coupling by Nylon column pins. The turntable is on the other side of the main shaft. And there are CZPT discs on each end of the turntable, and the turntable rotates between 2 CZPT discs and axially moves under pressure.<\/p>\n Movable pedestal is adjusted by feed gear with axial movement to adjust the space between 2 CZPT sections. A feather key is set between movable pedestal and machine case and pushed by trapezoidal screw.<\/p>\n The cover is a welded structure which is connected with the case by pin roll. Withdraw the whole movable pedestal into the cover and loosen the locking bolts before opening the cover. Keep the surface clean and withdraw the movable pedestal into the cover before closing the cover. Then fix uniformly fasten bolts.<\/p>\n 2.Coupling<\/strong><\/p>\n Coupling is connected by Nylon column pin with the character of easy dismounting and maintenance. It meets the requirement of displacement of feeding and relieving and transmit torque<\/p>\n 3.Feed gear<\/strong><\/p>\n Feed gear covers worm gear reduction system. Under force of worm gear, trapezoidal thread screw rotates and drive the movable pedestal forward or backward. The movable pedestal moves 0.23mm for each circle of motor. When rotating clockwise, it moves forward while anticlockwise backward.<\/p>\n Field Usage<\/p>\n \n \n \n \n \n \n \n \u00a0<\/p>\n \n \n Profil de l'entreprise<\/p>\n \n \n \n \n \n \n \n \n \n \n \n Les arbres cannel\u00e9s sont les paliers les plus courants pour les machines-outils. Ils sont fabriqu\u00e9s dans une grande vari\u00e9t\u00e9 de mat\u00e9riaux, notamment des m\u00e9taux et des non-m\u00e9taux comme le Delrin et le nylon. Leur conception vise souvent \u00e0 r\u00e9duire la d\u00e9formation. Le profil des dents se d\u00e9forme avec le temps, l'arbre \u00e9tant utilis\u00e9 sur une longue p\u00e9riode. Les arbres cannel\u00e9s sont disponibles dans une vaste gamme de mat\u00e9riaux et de longueurs.<\/p>\n Les arbres cannel\u00e9s sont utilis\u00e9s dans de nombreuses applications et industries. Ils constituent un dispositif anti-rotation efficace et un moyen fiable de transmettre le couple. D'autres types d'arbres existent, notamment les arbres clavet\u00e9s, mais les cannelures restent les plus pratiques pour la transmission du couple. Cet article pr\u00e9sente les fonctions des cannelures et explique pourquoi elles repr\u00e9sentent un choix optimal. Vous trouverez ci-dessous quelques exemples d'applications et d'industries o\u00f9 les cannelures sont utilis\u00e9es. Il existe de nombreux types d'arbres cannel\u00e9s. Chaque type pr\u00e9sente une h\u00e9lice de rainures r\u00e9guli\u00e8rement espac\u00e9es sur sa surface ext\u00e9rieure. Ces rainures sont soit parall\u00e8les, soit en d\u00e9veloppante. Leur forme permet leur assemblage avec des engrenages et la conversion de mouvements rotatifs et lin\u00e9aires. Les cannelures sont souvent lamin\u00e9es \u00e0 froid ou taill\u00e9es. Ces derni\u00e8res offrent une r\u00e9sistance sup\u00e9rieure. Ces types d'arbres sont couramment utilis\u00e9s dans des applications exigeant une r\u00e9sistance, une pr\u00e9cision et une r\u00e9gularit\u00e9 \u00e9lev\u00e9es. There are several methods used to fabricate a splined shaft. Key and splined shafts are constructed from 2 separate parts that are shaped in a synchronized manner to transfer torque uniformly. Hot rolling is 1 method, while cold rolling utilizes low temperatures to form metal. Both methods enhance mechanical properties, surface finishes, and precision. The advantage of cold rolling is its cost-effectiveness. L'arbre cannel\u00e9 est un composant m\u00e9canique de forme h\u00e9lico\u00efdale, form\u00e9 par l'espacement r\u00e9gulier des cannelures dans un anneau circulaire. Ces cannelures peuvent \u00eatre \u00e0 c\u00f4t\u00e9s parall\u00e8les ou en d\u00e9veloppante. Elles minimisent la concentration des contraintes dans les articulations fixes et peuvent \u00eatre utilis\u00e9es pour des mouvements rotatifs et lin\u00e9aires. Dans certains cas, les cannelures sont roul\u00e9es plut\u00f4t que taill\u00e9es. Cette derni\u00e8re m\u00e9thode offre une meilleure durabilit\u00e9 et est souvent privil\u00e9gi\u00e9e dans les applications exigeant une r\u00e9sistance \u00e9lev\u00e9e, une grande pr\u00e9cision et un \u00e9tat de surface lisse.

Fonctions<\/h2>\n
Les arbres cannel\u00e9s peuvent \u00eatre de diff\u00e9rents types, selon l'application et le syst\u00e8me m\u00e9canique concern\u00e9. Les diff\u00e9rences entre ces types r\u00e9sident notamment dans la conception des dents, la r\u00e9sistance globale, la transmission de la concentricit\u00e9 de rotation, la capacit\u00e9 de glissement et la tol\u00e9rance au d\u00e9salignement. Vous trouverez ci-dessous quelques exemples de cannelures, ainsi que certains de leurs avantages. Les diff\u00e9rences entre ces types ne sont pas exclusives\u00a0; chaque type pr\u00e9sente des avantages et des inconv\u00e9nients sp\u00e9cifiques.
Un arbre cannel\u00e9 est un arbre cylindrique comportant des dents ou des rainures correspondant \u00e0 une position angulaire pr\u00e9cise. Ceci permet \u00e0 l'arbre de transmettre un couple tout en maintenant une correspondance angulaire entre les rainures. Un arbre cannel\u00e9 est d\u00e9fini comme un \u00e9l\u00e9ment cylindrique pr\u00e9sentant plusieurs rainures usin\u00e9es sur sa circonf\u00e9rence. Ces rainures, r\u00e9guli\u00e8rement espac\u00e9es, forment une s\u00e9rie de clavettes. Ces caract\u00e9ristiques conf\u00e8rent \u00e0 l'arbre une forme arrondie et lui permettent de s'embo\u00eeter parfaitement dans un \u00e9l\u00e9ment cylindrique cannel\u00e9.
While the most common applications of splines are for shortening or extending shafts, they can also be used to secure mechanical assemblies. An “involute spline” spline has a groove that is wider than its counterparts. The result is that a splined shaft will resist separation during operation. They are an ideal choice for applications where deflection is an issue.
A spline shaft’s radial torsion load distribution is equally distributed, unless a bevel gear is used. The radial torsion load is evenly distributed and will not exert significant load concentration. If the spline couplings are not aligned correctly, the spline connection can fail quickly, causing significant fretting fatigue and wear. A couple of papers discuss this issue in more detail.![\"arbre](\"https:\/\/img.hzpt.com\/img\/spline_shaft\/T_splineshaft_2.webp\")
<\/p>\nTypes<\/h2>\n
Une autre diff\u00e9rence entre les arbres cannel\u00e9s internes et externes r\u00e9side dans leur fabrication. Les premiers sont en bois, tandis que les seconds sont en acier ou en alliage m\u00e9tallique. La fabrication des arbres cannel\u00e9s consiste \u00e0 usiner des rainures dans la surface du mat\u00e9riau. Ces deux proc\u00e9d\u00e9s sont co\u00fbteux et requi\u00e8rent un savoir-faire sp\u00e9cialis\u00e9. Le principal avantage des arbres cannel\u00e9s est leur grande polyvalence.
In general, splined shafts are used in machinery where the rotation is transferred to an internal splined member. This member can be a gear or some other rotary device. These types of shafts are often packaged together as a hub assembly. Cleaning and lubricating are essential to the life of these components. If you’re using them on a daily basis, you’ll want to make sure to regularly inspect them.
Crowned splines are usually involute. The teeth of these splines form a spiral pattern. They are used for smaller diameter shafts because they add strength. Involute splines are also used on instrument drives and valve shafts. Serration standards are found in the SAE. Both kinds of splines can also contain a ball bearing for high torque. The difference between the 2 types of splines is the number of teeth on the shaft.
Les cannelures internes pr\u00e9sentent de nombreux avantages par rapport aux cannelures externes. Par exemple, un arbre \u00e0 cannelures internes peut \u00eatre fabriqu\u00e9 \u00e0 l'aide d'une meule plut\u00f4t que d'une machine CNC. Ce proc\u00e9d\u00e9 est \u00e9galement plus pr\u00e9cis et plus \u00e9conomique. De plus, il permet un cycle de fabrication plus court, ce qui est essentiel pour le cannelage des machines \u00e0 grande vitesse. Enfin, il stabilise la phase relative entre la cannelure et le filetage.![\"arbre](\"https:\/\/img.hzpt.com\/img\/spline_shaft\/C_splineshaft_2.webp\")
<\/p>\nM\u00e9thodes de fabrication<\/h2>\n
Cold forming is 1 method, as well as machining and assembling. Cold forming is a unique process that allows the spline to be shaped to the desired shape. The resulting shape provides maximum contact area and torsional strength. Standard splines are available in standard sizes, but custom lengths can also be ordered. CZPT offers various auxiliary equipment, such as mating sleeves and flanged bushings.
Le forgeage \u00e0 froid est une autre m\u00e9thode. Ce proc\u00e9d\u00e9 permet de produire de longs arbres cannel\u00e9s utilis\u00e9s dans les h\u00e9lices automobiles. Apr\u00e8s le fraisage de la partie cannel\u00e9e, celle-ci est usin\u00e9e sur une machine \u00e0 tailler les pignons. L'\u00e9crouissage renforce la r\u00e9sistance \u00e0 la base de la cannelure. Ce proc\u00e9d\u00e9 peut \u00eatre utilis\u00e9 pour les roulements, les engrenages et d'autres composants m\u00e9caniques. Vous trouverez ci-dessous les m\u00e9thodes de fabrication des arbres cannel\u00e9s.
Les cannelures parall\u00e8les sont la m\u00e9thode de fabrication d'arbres cannel\u00e9s la plus simple. Elles sont g\u00e9n\u00e9ralement soud\u00e9es \u00e0 l'arbre, tandis que les cannelures en d\u00e9veloppante sont r\u00e9alis\u00e9es en m\u00e9tal ou en mat\u00e9riaux non m\u00e9talliques. Les cannelures sont disponibles dans une grande vari\u00e9t\u00e9 de longueurs et de mat\u00e9riaux. Le proc\u00e9d\u00e9 est g\u00e9n\u00e9ralement compl\u00e9t\u00e9 par une op\u00e9ration de fraisage. La pi\u00e8ce est mise en rotation pour cr\u00e9er la surface cannel\u00e9e.
Splines are internal or external grooves in a splined shaft. They work in combination with keyways to transfer torque. Male and female splines are used in gears. Female and male splines correspond to 1 another to ensure proper angular correspondence. Involute splines have more surface area and thus are stronger than external splines. Moreover, they help the shaft fit into a grooved cylindrical member without misalignment.
A variety of other methods of manufacturing a splined shaft can be used to produce a splined shaft. Spline shafts can be produced using broaching and shaping, 2 precision machining methods. Broaching uses a metal tool with successively larger teeth to remove metal and create ridges and holes in the surface of a material. However, this process is expensive and requires special expertise.![\"arbre](\"https:\/\/img.hzpt.com\/img\/spline_shaft\/B_splineshaft_2.webp\")
<\/p>\nApplications<\/h2>\n
Splined shafts are commonly made of carbon steel. This alloy steel has a low carbon content, making it easy to work with. Carbon steel is a great choice for splines because it is malleable. Generally, high-quality carbon steel provides a consistent motion. Steel alloys are also available that contain nickel, chromium, copper, and other metals. If you’re unsure of the right material for your application, you can consult a spline chart.
Splines are a versatile mechanical component. They are easy to cut and fit. Splines can be internal or external, with teeth positioned at equal intervals on both sides of the shaft. This allows the shaft to engage with the hub around the entire circumference of the hub. It also increases load capacity by creating a constant multiple-tooth point of contact with the hub. For this reason, they’re used extensively in rotary and linear motion.
Splined shafts are used in a wide variety of industries. CZPT Inc. offers custom and standard splined shafts for a variety of applications. When choosing a splined shaft for a specific application, consider the surrounding mated components, torque requirements, and size requirements. These 3 factors will make it the ideal choice for your rotary equipment. And you’ll be pleased with the end result!
There are many types of splines and their applications are endless. They transfer torque and angular misalignment between parts, and they also enable the axial rotation of assembled components. Therefore, splines are an essential component of machinery and are used in a wide range of applications. This type of shaft can be found in various types of machines, from household appliances to industrial machinery. So, the next time you’re looking for a splined shaft, make sure you look for a splined one.<\/p>\n![\"China](\"https:\/\/img.hzpt.com\/img\/spline_shaft\/spline_shaft_l1.webp\")
