  • 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.

China Professional Co Rotating Twin Screw Extruder Gearbox for Extrusion Machine cvt gearbox

Product Description

Polytek co-rotating twin-screw extruders are designed for maximum reliability, ease-of-use and flexibility. We offer turn-key solution for all types of material compounding applications.

we are proud to introduce our PTH series extruder which equiped with high torque and high speed gear box, desinged with specific torque of

12Nm/cm3 to achieve high screw filling rate, which results in a decrease of melt temperature, thus improving compound quality.

what is twin screw extruder 

Co-rotating twin-screw extruder : Due to the co-rotating twin-screw has the opposite speed at the meshing point, 1 screw pulls the material into the meshing gap, and the other screw pushes the material out of the gap, resulting in material from 1 screw turns to the other screw and advances in a “∞” shape. Since the gap of the meshing zone is small, the speed of the meshing screw and the groove are opposite in direction, so that the cutting speed is high, and the self-cleaning effect is good, that is, any accumulated material adhering to the screw can be scraped off, thereby The residence time of the material is very short, so the twin screw extruder is mainly used for compounding and pelletizing .

Polytek also have 2 stage extruder for PVC compound and high filler masterbatch extrusion.

Limitations of Maximum Torque Handling in Plastic Gearboxes

While plastic gearboxes offer numerous advantages, they do have limitations when it comes to handling maximum torque:

  • Material Strength: Plastic materials generally have lower tensile strength and fatigue resistance compared to metals. This can limit the amount of torque that plastic gearboxes can transmit before experiencing deformation or failure.
  • Size and Design: The size and design of plastic gear teeth play a significant role in torque handling. Smaller gear teeth with less surface area may struggle to withstand high torque loads without premature wear or damage.
  • Temperature Sensitivity: High temperatures can negatively impact the mechanical properties of plastics, potentially leading to a reduction in their torque-carrying capacity. Extreme temperature fluctuations may exacerbate this limitation.
  • Operating Conditions: The operating environment, such as exposure to harsh chemicals, abrasive particles, or excessive moisture, can affect the integrity of plastic gear materials and reduce their ability to handle high torque loads.
  • Application Type: Plastic gearboxes are better suited for applications with moderate torque requirements. High-torque applications, such as heavy industrial machinery, may exceed the capabilities of plastic gearboxes.

It’s important to consider the specific torque demands of an application and select an appropriate gearbox material accordingly. While plastic gearboxes are lightweight, cost-effective, and suitable for many applications, they may not be the ideal choice for extremely high-torque scenarios.

plastic gearbox

Suitability of Plastic Gearboxes for Industrial and Consumer Applications

Plastic gearboxes offer versatility and are well-suited for both industrial and consumer applications due to their unique properties:

  • Industrial Applications: Plastic gearboxes find applications in various industrial sectors, such as automotive, packaging, food processing, and automation. They are suitable for light to moderate load applications where corrosion resistance, noise reduction, and customization options are important.
  • Consumer Applications: Plastic gearboxes are also widely used in consumer products, including household appliances (e.g., blenders, mixers, washing machines), power tools, garden equipment, and toys. Their lightweight construction, lower noise output, and cost-effectiveness make them popular choices in these applications.

While plastic gearboxes may not be suitable for heavy-duty industrial applications with high torque and load requirements, advances in plastic materials and manufacturing processes have expanded their capabilities, allowing them to handle more demanding tasks than before. Ultimately, the choice between using plastic or metal gearboxes depends on the specific needs and performance criteria of the application.

The Areas of a Gearbox

There are several elements of a Gearbox, and this write-up will support you recognize its features and parts. Understand about its upkeep and proper treatment, and you will be on your way to repairing your automobile. The complexity of a Gearbox also can make it effortless to make problems. Find out about its functions and elements so that you may be able to make the best choices attainable. Read on to find out more. Then, get your auto completely ready for wintertime!

Factors

Gearboxes are entirely built-in mechanical elements that consist of a sequence of gears. They also include shafts, bearings, and a flange to mount a motor. The terms gearhead and gearbox are not typically used interchangeably in the motion market, but they are often synonymous. Gearheads are open gearing assemblies that are mounted in a device frame. Some more recent styles, this sort of as battery-driven cellular units, demand tighter integration.
The energy losses in a gearbox can be divided into no-load and load-dependent losses. The no-load losses originate in the equipment pair and the bearings and are proportional to the ratio of shaft pace and torque. The latter is a function of the coefficient of friction and speed. The no-load losses are the most serious, because they represent the biggest proportion of the total reduction. This is due to the fact they enhance with speed.
Temperature measurement is another critical preventive routine maintenance practice. The warmth created by the gearbox can injury components. Substantial-temperature oil degrades speedily at substantial temperatures, which is why the sump oil temperature must be monitored periodically. The greatest temperature for R&O mineral oils is 93degC. However, if the sump oil temperature is more than 200degF, it can lead to seal harm, equipment and bearing dress in, and premature failure of the gearbox.
No matter of its size, the gearbox is a essential component of a car’s drivetrain. Regardless of whether the auto is a sports activities automobile, a luxurious automobile, or a farm tractor, the gearbox is an crucial ingredient of the automobile. There are two principal sorts of gearbox: standard and precision. Each and every has its own rewards and disadvantages. The most important thought when picking a gearbox is the torque output.
The primary shaft and the clutch shaft are the two major components of a gearbox. The major shaft operates at engine pace and the countershaft may possibly be at a reduced pace. In addition to the primary shaft, the clutch shaft has a bearing. The gear ratio determines the sum of torque that can be transferred in between the countershaft and the main shaft. The generate shaft also has an additional title: the propeller shaft.
The gears, shafts, and hub/shaft relationship are made in accordance to stamina layout specifications. Based on the software, each element must be capable to face up to the typical stresses that the system will experience. Quite often, the least speed assortment is 10 to 20 m/s. However, this range can vary amongst diverse transmissions. Typically, the gears and shafts in a gearbox must have an stamina restrict that is significantly less than that limit.
The bearings in a gearbox are regarded as put on parts. Whilst they should be replaced when they put on down, they can be retained in services considerably more time than their intended L10 existence. Utilizing predictive servicing, makers can decide when to change the bearing just before it damages the gears and other elements. For a gearbox to perform correctly, it have to have all the components listed above. And the clutch, which permits the transmission of torque, is regarded as the most important part.

Capabilities

A gearbox is a completely built-in mechanical component that is composed of mating gears. It is enclosed in a housing that residences the shafts, bearings, and flange for motor mounting. The objective of a gearbox is to improve torque and change the velocity of an motor by connecting the two rotating shafts together. A gearbox is normally created up of numerous gears that are joined collectively utilizing couplings, belts, chains, or hollow shaft connections. When energy and torque are held consistent, pace and torque are inversely proportional. The velocity of a gearbox is decided by the ratio of the gears that are engaged to transmit electricity.
The equipment ratios in a gearbox are the amount of steps a motor can just take to transform torque into horsepower. The amount of torque required at the wheels is dependent on the operating circumstances. A automobile wants a lot more torque than its peak torque when it is moving from a standstill. Consequently, the initial gear ratio is employed to enhance torque and move the automobile forward. To move up a gradient, a lot more torque is needed. To keep momentum, the intermediate gear ratio is employed.
As metal-to-metal speak to is a common lead to of gearbox failure, it is essential to keep an eye on the issue of these elements carefully. The primary emphasis of the proactive collection of tests is abnormal put on and contamination, whilst the preventative exams emphasis on oil problem and additive depletion. The AN and ferrous density checks are exceptions to this rule, but they are used a lot more for detecting abnormal additive depletion. In addition, lubrication is essential to the effectiveness of gearboxes.

Routine maintenance

Daily upkeep is a vital factor of the life cycle of a gearbox. For the duration of maintenance, you should inspect all gearbox link components. Any unfastened or broken link component must be tightened right away. Oil can be examined employing an infrared thermometer and particle counters, spectrometric examination, or ferrography. You ought to examine for extreme dress in and tear, cracks, and oil leaks. If any of these components fail, you should replace them as shortly as possible.
Proper evaluation of failure designs is a required portion of any preventative routine maintenance system. This examination will support determine the root trigger of gearbox failures, as nicely as program for long term preventative servicing. By correctly arranging preventative upkeep, you can keep away from the expense and inconvenience of fixing or changing a gearbox prematurely. You can even outsource gearbox upkeep to a company whose specialists are experienced in this discipline. The benefits of the examination will support you produce a far more efficient preventative upkeep program.
It is essential to check out the problem of the gearbox oil periodically. The oil need to be changed according to its temperature and the hours of procedure. The temperature is a considerable determinant of the frequency of oil modifications. Larger temperatures demand more frequent alterations, and the amount of protection from dampness and drinking water minimizes by 75%. At elevated temperatures, the oil’s molecular construction breaks down much more rapidly, inhibiting the formation of a protective film.
The good news is, the gear sector has produced innovative technologies and services that can aid plant operators decrease their downtime and make sure ideal overall performance from their industrial gears. Right here are ten methods to guarantee that your gearbox proceeds to provide its purpose. When you are making ready for upkeep, often hold in head the adhering to suggestions:
Standard vibration evaluation is a vital part of gearbox upkeep. Enhanced vibration indicators impending issues. Visually examine the interior gears for signs of spiraling and pitting. You can use engineers’ blue to check out the contact pattern of gear enamel. If there is a misalignment, bearings or housings are worn and need substitution. Also make certain the breathers remain clean. In dirty purposes, this is much more tough to do.
Appropriate lubrication is another key element in the existence of gearboxes. Proper lubrication prevents failure. The oil should be cost-free of overseas resources and have the suitable quantity of movement. Appropriate lubricant assortment depends on the type of gear, reduction ratio, and input energy. In addition to oil degree, the lubricant have to be regulated for the dimensions and form of gears. If not, the lubricant ought to be transformed.
Deficiency of proper lubrication decreases the power of other gears. Incorrect maintenance decreases the daily life of the transmission. Whether or not the transmission is overloaded or undersized, abnormal vibration can harm the gear. If it is not correctly lubricated, it can be damaged past repair. Then, the need for substitution gears might come up. However, it is not a time to waste a great deal of money and time on repairs.
