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.
- Procure ajuda profissional: 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.

Differences between Manual and Automatic Mower Gearboxes
Manual and automatic mower gearboxes differ in their operation, control, and convenience:
- Operation: Manual gearboxes require the user to engage and disengage gears manually using a clutch or lever. Automatic gearboxes, on the other hand, change gears automatically based on speed and load conditions.
- Control: Manual gearboxes provide more direct control over gear selection, allowing the user to choose the appropriate gear for specific tasks. Automatic gearboxes, however, offer a hands-free experience with gear changes managed by the gearbox itself.
- Convenience: Automatic gearboxes are more convenient for users who prefer a hassle-free experience. They eliminate the need to manually shift gears, making operation simpler and more user-friendly.
- Complexity: Automatic gearboxes are more complex in design compared to manual ones due to the presence of sensors, electronic controls, and additional components required for automatic shifting.
- Eficiência: Manual gearboxes can provide better control over power delivery and may be more efficient in certain situations. However, automatic gearboxes optimize gear changes for fuel efficiency and performance.
- Cost: Automatic gearboxes are generally more expensive to manufacture and repair due to their complexity. Manual gearboxes are simpler and often more affordable.
The choice between manual and automatic mower gearboxes depends on user preference, the level of control desired, and the intended use of the mower. Both types have their advantages and disadvantages, and the decision should be based on the user’s needs and priorities.

Sinais de uma caixa de engrenagens defeituosa no cortador de grama
Uma caixa de engrenagens defeituosa em um cortador de grama pode levar a um desempenho ruim e a reparos potencialmente caros se não for consertada rapidamente. Aqui estão alguns sinais comuns que indicam que a caixa de engrenagens do seu cortador de grama pode estar apresentando problemas:

- Dificuldade em trocar de marcha: Se o seu cortador de grama tiver transmissão manual, dificuldade em trocar de marcha ou marchas que saem do lugar podem ser um sinal de problema na caixa de câmbio.
- Vazamento de óleo: Vazamentos visíveis de óleo ao redor da carcaça da caixa de câmbio sugerem um possível problema de vedação ou junta que precisa de atenção.
- Vibração excessiva: Vibrações ou trepidações excessivas durante o funcionamento do cortador de grama podem indicar engrenagens desalinhadas ou outros problemas internos na caixa de engrenagens.
- Corte irregular: Se o seu cortador de relva estiver a deixar falhas na relva, pode dever-se a um problema na caixa de velocidades que afeta a sincronização das lâminas.
- Engajamento atrasado: Um atraso entre o engate da transmissão e o movimento do cortador de grama pode indicar um problema com o mecanismo de engate da caixa de câmbio.
- Cheiro de queimado: Um odor de queimado ou superaquecimento pode ser resultado do atrito causado por componentes da caixa de engrenagens danificados ou com lubrificação inadequada.
Se você notar algum desses sinais, é crucial resolver o problema imediatamente. Ignorar problemas na caixa de câmbio pode levar a danos maiores e reparos mais caros no futuro. Recomenda-se consultar um profissional para um diagnóstico preciso e os reparos adequados.
