Descrizione del prodotto
Main products
Coupling refers to a device that connects 2 shafts or shafts and rotating parts, rotates together during the transmission of motion and power, and does not disengage under normal conditions. Sometimes it is also used as a safety device to prevent the connected parts from bearing excessive load, which plays the role of overload protection.
Couplings can be divided into rigid couplings and flexible couplings.
Rigid couplings do not have buffering property and the ability to compensate the relative displacement of 2 axes. It is required that the 2 axes be strictly aligned. However, such couplings are simple in structure, low in manufacturing cost, convenient in assembly and disassembly, and maintenance, which can ensure that the 2 axes are relatively neutral, have large transmission torque, and are widely used. Commonly used are flange coupling, sleeve coupling and jacket coupling.
Flexible coupling can also be divided into flexible coupling without elastic element and flexible coupling with elastic element. The former type only has the ability to compensate the relative displacement of 2 axes, but cannot cushion and reduce vibration. Common types include slider coupling, gear coupling, universal coupling and chain coupling; The latter type contains elastic elements. In addition to the ability to compensate the relative displacement of 2 axes, it also has the functions of buffering and vibration reduction. However, due to the strength of elastic elements, the transmitted torque is generally inferior to that of flexible couplings without elastic elements. Common types include elastic sleeve pin couplings, elastic pin couplings, quincunx couplings, tire type couplings, serpentine spring couplings, spring couplings, etc
Coupling performance
1) Mobility. The movability of the coupling refers to the ability to compensate the relative displacement of 2 rotating components. Factors such as manufacturing and installation errors between connected components, temperature changes during operation and deformation under load all put CZPT requirements for mobility. The movable performance compensates or alleviates the additional load between shafts, bearings, couplings and other components caused by the relative displacement between rotating components.
(2) Buffering. For the occasions where the load is often started or the working load changes, the coupling shall be equipped with elastic elements that play the role of cushioning and vibration reduction to protect the prime mover and the working machine from little or no damage.
(3) Safe, reliable, with sufficient strength and service life.
(4) Simple structure, easy to assemble, disassemble and maintain.
How to select the appropriate coupling type
The following items should be considered when selecting the coupling type.
1. The size and nature of the required transmission torque, the requirements for buffering and damping functions, and whether resonance may occur.
2. The relative displacement of the axes of the 2 shafts is caused by manufacturing and assembly errors, shaft load and thermal expansion deformation, and relative movement between components.
3. Permissible overall dimensions and installation methods, and necessary operating space for assembly, adjustment and maintenance. For large couplings, they should be able to be disassembled without axial movement of the shaft.
In addition, the working environment, service life, lubrication, sealing, economy and other conditions should also be considered, and a suitable coupling type should be selected by referring to the characteristics of various couplings.

Requisiti di manutenzione per i giunti a ingranaggi
Come qualsiasi componente meccanico, anche i giunti a ingranaggi richiedono una manutenzione regolare per garantire prestazioni ottimali, affidabilità e durata nel tempo. Una corretta manutenzione può contribuire a prevenire guasti imprevisti e fermi macchina, con conseguente risparmio sui costi e aumento della produttività. Ecco i principali requisiti di manutenzione per i giunti a ingranaggi:
- Lubrificazione: Una lubrificazione regolare e adeguata è essenziale per i giunti a ingranaggi. I denti degli ingranaggi e le superfici di accoppiamento del giunto devono essere adeguatamente lubrificati per ridurre al minimo l'attrito e l'usura. L'intervallo di lubrificazione e il tipo di lubrificante utilizzato dipendono dall'applicazione, dal carico e dalle condizioni operative. È fondamentale seguire le raccomandazioni del produttore per quanto riguarda gli intervalli di lubrificazione e il lubrificante appropriato da utilizzare.
- Ispezioni: È opportuno eseguire ispezioni di routine per verificare la presenza di segni di usura, disallineamento o danni. Le ispezioni visive possono aiutare a individuare eventuali anomalie, come vaiolatura, graffi o corrosione sui denti degli ingranaggi. Inoltre, le ispezioni possono identificare eventuali problemi di disallineamento che potrebbero richiedere un intervento per prevenire ulteriori danni.
- Monitoraggio della coppia: Il monitoraggio della coppia trasmessa attraverso il giunto può aiutare a identificare eventuali aumenti anomali che potrebbero indicare un problema nel sistema. Cambiamenti improvvisi nei livelli di coppia potrebbero segnalare un disallineamento o altri problemi che richiedono attenzione.
- Verifiche di allineamento: Il controllo e la correzione periodica dell'allineamento degli alberi sono fondamentali per il corretto funzionamento dei giunti a ingranaggi. Un disallineamento può causare un'usura maggiore e un guasto prematuro del giunto. Un allineamento corretto riduce le sollecitazioni sul giunto e sulle apparecchiature collegate.
- Monitoraggio della temperatura: Il monitoraggio della temperatura di esercizio del giunto può fornire informazioni su potenziali problemi. Temperature anormalmente elevate potrebbero indicare una lubrificazione insufficiente o altri problemi che necessitano di essere approfonditi.
- Rimozione e pulizia del giunto: Rimuovere periodicamente il giunto per pulirlo e ispezionarne i componenti interni può essere vantaggioso, soprattutto in ambienti difficili o sporchi. Ciò consente un'ispezione più accurata e contribuisce a mantenere le prestazioni del giunto.
- Sostituzione dei componenti usurati: Se uno qualsiasi dei componenti del giunto a ingranaggi, come guarnizioni o paraoli, risulta usurato o danneggiato, deve essere sostituito tempestivamente per preservare l'integrità del giunto e prevenire perdite.
- Conservazione corretta: Se il giunto viene temporaneamente rimosso dal servizio o immagazzinato, deve essere conservato in un ambiente pulito e asciutto per prevenire la corrosione e i danni ai componenti.
È fondamentale seguire le linee guida e le raccomandazioni di manutenzione del produttore per lo specifico modello di giunto a ingranaggi utilizzato. Una manutenzione regolare e il rispetto delle procedure corrette possono contribuire a prolungare la durata dei giunti a ingranaggi e a garantire un funzionamento affidabile ed efficiente del sistema meccanico.
