Applications
X helical gear units for double-screw extruders with parallel drive shafts and the same direction of screw rotation are used mainly in the manufacture of granulates and the refining of raw plastics. Other areas of application include:
- Paint and lacquer industry
- Washing agent industry
- Foodstuff industry (e.g. bread, pasta)
- Animal-feed industry (dog, cat other animal food
Maintenance of the gearbox of the dual-screw extruder
1. The gear box of the dual-screw extruder should be well-ventilated, and the working environment temperature should be within the range of 5-35 °C.
2. Always check the oil quantity of the gear lubricating oil in the box to ensure that the transmission parts in the box are well lubricated.
3. Pay attention to check the bearing parts of the box frequently. The oil temperature of the oil tank of the transmission box should not exceed 70 ºC during operation.
4. The newly put into use gearbox needs to replace the lubricating oil after 250 hours of operation. The oil change time depends on the state of the oil. It is recommended to replace it after 4000-8000 hours of operation or once a year.
5. The gearbox of the dual-screw extruder needs to be regularly maintained and inspected once a year
Operating Process
1. The gear on the input shaft is driven by the motor and starts to rotate.
2. The rotating input gear meshes with other gears inside the gearbox, transmitting power.
3. Different-sized gears within the gearbox are combined to form a gear train. Through continuous meshing and rotation, the high-speed, low-torque power from the input shaft gradually converts into low-speed, high-torque output.
4. The output shaft is connected to the last gear and transfers the output torque to the load.
5. Gear reduction gearboxes typically include lubrication and cooling systems to ensure smooth operation and prevent overheating and damage.
6. Our extruder gearbox converts high-speed, low-torque power into low-speed, high-torque output by changing the size ratios and meshing arrangements of different gears, achieving the function of speed reduction.
Types of Gearboxes:
Based on customer requirements, gear reduction gearboxes can be classified according to the size of the output shaft, center distance of the output shaft, output speed, and torque. Alternatively, we can provide several commonly used types of gearboxes for customers to choose from.

Safety Precautions when Working with Mower Gearboxes
Working with mower gearboxes requires careful attention to safety to prevent accidents and injuries. Follow these safety precautions:
- Disconnect Power: Before performing any maintenance or adjustments, turn off the mower’s engine and disconnect the spark plug wire to prevent accidental starts.
- Wait for Cooling: Allow the gearbox to cool down if it has been running, as it can become hot during operation.
- Wear Protective Gear: Use appropriate personal protective equipment (PPE), such as gloves, safety glasses, and closed-toe shoes, to protect yourself from debris and moving parts.
- Stabilize the Mower: Make sure the mower is on a level surface and properly stabilized before attempting any work on the gearbox.
- Read the Manual: Refer to the mower’s manual for specific safety instructions and procedures related to gearbox maintenance.
- Use the Right Tools: Always use the correct tools for the job, and ensure they are in good condition. Incorrect tools can lead to accidents and damage.
- Avoid Loose Clothing: Wear clothing that fits well and doesn’t risk getting caught in moving parts.
- Keep Hands Clear: Keep your hands and fingers away from the gearbox and belts while the engine is running or while performing maintenance.
- Properly Ventilate: If you’re working in an enclosed space, ensure proper ventilation to prevent exposure to exhaust fumes.
- One Task at a Time: Focus on one task at a time. Avoid distractions and multitasking while working on the mower gearbox.
- Maintain a Clean Work Area: Keep the work area clean and organized to avoid tripping hazards and to ensure easy access to tools.
- Replace Guards and Covers: After performing maintenance, ensure all guards and covers are properly reinstalled before operating the mower.
- Dispose of Fluids Properly: If you need to drain fluids from the gearbox, dispose of them according to local regulations.
- Seek Professional Help: If you’re unsure about any maintenance or repairs, or if the task requires specialized knowledge, consult a professional or authorized service center.
Adhering to these safety precautions will help you work safely and effectively with mower gearboxes, reducing the risk of accidents and injuries.
Differenze tra cambio manuale e automatico per tosaerba
I cambi manuali e automatici dei tosaerba differiscono per funzionamento, controllo e praticità:
- Operazione: Nei cambi manuali, l'utente deve innestare e disinnestare le marce manualmente tramite frizione o leva. I cambi automatici, invece, cambiano marcia automaticamente in base alla velocità e al carico.
- Controllare: I cambi manuali offrono un controllo più diretto sulla selezione delle marce, consentendo all'utente di scegliere la marcia più adatta a specifiche esigenze. I cambi automatici, invece, offrono un'esperienza senza intervento umano, con il cambio di marcia gestito direttamente dal cambio stesso.
- Convenienza: I cambi automatici sono più comodi per gli utenti che preferiscono un'esperienza senza complicazioni. Eliminano la necessità di cambiare marcia manualmente, rendendo il funzionamento più semplice e intuitivo.
- Complessità: I cambi automatici sono più complessi nella progettazione rispetto a quelli manuali a causa della presenza di sensori, controlli elettronici e componenti aggiuntivi necessari per il cambio automatico.
- Efficienza: I cambi manuali offrono un maggiore controllo sull'erogazione di potenza e possono risultare più efficienti in determinate situazioni. Tuttavia, i cambi automatici ottimizzano i cambi di marcia per massimizzare il risparmio di carburante e le prestazioni.
- Costo: I cambi automatici sono generalmente più costosi da produrre e riparare a causa della loro complessità. I cambi manuali sono più semplici e spesso più economici.
La scelta tra cambio manuale e automatico per il tosaerba dipende dalle preferenze dell'utente, dal livello di controllo desiderato e dall'uso previsto del tosaerba. Entrambi i tipi presentano vantaggi e svantaggi, e la decisione dovrebbe basarsi sulle esigenze e sulle priorità dell'utente.
Segnali di un cambio del tosaerba difettoso
Un riduttore del tosaerba difettoso può causare prestazioni scadenti e riparazioni potenzialmente costose se non viene riparato tempestivamente. Ecco alcuni segnali comuni che indicano che il riduttore del vostro tosaerba potrebbe avere dei problemi:
- Rumori insoliti: Rumori di sfregamento, scricchiolio o stridio durante il funzionamento possono indicare ingranaggi o cuscinetti usurati o danneggiati nel cambio.
- Interruzione di corrente: Se il vostro tosaerba fatica a tagliare l'erba o ad avanzare in modo efficiente, il problema potrebbe essere dovuto a un guasto al cambio che compromette la trasmissione di potenza.
- Difficoltà nel cambio di marcia: Se il vostro tosaerba ha una trasmissione manuale, la difficoltà nel cambiare marcia o lo slittamento delle marce possono essere un segno di un problema al cambio.
- Perdita di petrolio: Perdite d'olio visibili intorno all'alloggiamento del cambio suggeriscono un potenziale problema alle guarnizioni o alle tenute che necessita di attenzione.
- Vibrazioni eccessive: Vibrazioni o scuotimenti eccessivi durante il funzionamento del tosaerba possono indicare un disallineamento degli ingranaggi o altri problemi interni al cambio.
- Taglio irregolare: Se il vostro tosaerba lascia chiazze d'erba irregolari, potrebbe essere dovuto a un problema con il riduttore che influisce sulla sincronizzazione delle lame.
- Coinvolgimento ritardato: Un ritardo tra l'innesto della trasmissione e il movimento del tosaerba può segnalare un problema al meccanismo di innesto del cambio.
- Odore di bruciato: Un odore di bruciato o di surriscaldamento potrebbe essere dovuto all'attrito causato da componenti del cambio danneggiati o lubrificati in modo inadeguato.
Se notate uno qualsiasi di questi segnali, è fondamentale intervenire tempestivamente. Ignorare i problemi al cambio può causare danni maggiori e riparazioni più costose in futuro. Si consiglia di consultare un professionista per una diagnosi accurata e le riparazioni appropriate.
