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 ℃ 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 (recommended to be operated by a professional maintenance engineer from KY). The work content is as follows:
1）Remove the cover of the gearbox, and check the wear and meshing of the working surfaces of the transmission reduction gears. If there are burrs or shallow pits on the meshing surface, it can be smoothed with oilstone; gears with serious wear should be prepared to purchase accessories. for replacement during the next maintenance.
2）Check the wear of each bearing. Clean the bearing first, and check the inner jacket for cracks; observe the noise of idling and the radial clearance. If no problem is found, add some grease and continue to use it.
3）Check whether the lubricating oil in the box is clean. If the oil is mixed with impurities or metal powder, filter the lubricating oil to remove impurities, and then make up the amount of lubricating oil.
4）After cleaning and checking the parts in the box, install the box cover; add enough grease to each bearing part, replace the new oil seal, and fasten the bearing cover.
5）Clean the outside of the gear box to keep the equipment clean.

How to Choose the Right Conical Twin Screw Extruder Gearbox
Assess the load and torque requirements
Know your load: Understand the peak load your specific industrial application will place on the gearbox. Whether you’re running a twin screw extruder or another type of machinery, you’ll need to know how much load your system will handle at its maximum.
Calculate torque and power: Don’t just guess—calculate the torque and horsepower requirements for your screw extruder. This will give you a concrete idea of what you need your gearbox to handle in terms of mechanical energy.
Material considerations: Remember the types of materials you’ll be processing through your system. Different materials may have different resistances, affecting the load and torque demands.
Plan for the future: It’s always a good idea to think about potential future expansions of your operations. Your current load requirements might change, so plan.
Examine the gear ratio and output speed
Crunch the numbers: Knowing how the gear ratio affects the output shaft speed and torque in your extruder gears is crucial. In layman’s terms, the gear ratio is the relationship between the speed at which the input shaft spins and the speed of the output shaft. A higher gear ratio can increase torque but will reduce speed, while a lower ratio does the opposite.
Define your needs: You must pinpoint exactly what output speed and torque your operation demands. This could be influenced by various factors, from the materials you’re processing to the speed at which your twin screw extruder operates.
Weigh gearbox efficiency
Check the efficiency rating: Gearbox efficiency isn’t just a number; it’s an indicator of how well the gearbox converts input energy into output. A higher efficiency percentage means less energy loss, translating to lower energy bills for your operation.
Understand axial forces: Axial forces can have a considerable impact on gearbox efficiency. Knowing how your gearbox manages these forces, often through thrust bearings, can give you an insight into its long-term efficiency. Poor management of axial forces can result in higher energy consumption and reduced lifespan of the gearbox components.
Size and mounting-they matter
Measure your space: Before making any decisions, carefully measure the area where the gearbox will be installed. Make sure to consider any spatial limitations that could restrict your options for size and mounting methods.
Compatibility is key: Consider how the new gearbox will integrate with your existing machinery, especially if you use specialized equipment like a twin screw extruder. You don’t want to discover compatibility issues after you’ve already made the purchase.
Don’t overlook the manufacturer and warranty
Evaluating reputation: To make an informed decision, delve into the manufacturer’s track record, specifically in gear manufacturing. Browse customer reviews for a real-world sense of the product’s performance and durability.
Exploring repair and warranty options: Don’t just gloss over the warranty information; understand what it encompasses. Look into whether the manufacturer offers a range of gearbox repair services, and clarify what their warranty covers—parts, labor, or both.
