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.

worm reducer

Is a worm gear reducer gearbox right for your application?

If you’re interested in gear reduction and wondering if a worm gear reducer gearbox is right for your application, you’ve come to the right place. This gear reducer gearbox is efficient and compact. In addition, it has small clearances and is easy to install. Let’s take a closer look.

This is a reducer gearbox

Worm reducer gearbox is a type of reduction gear used in machinery. This gear reduces the output speed by changing the ratio of input to output. Gears come in a wide range of sizes and can be made from a variety of materials, including aluminum, cast iron, and stainless steel. Its efficiency depends on the ratio and size of the gears. It is usually used in low speed applications. But it can also be used as an auxiliary braking device for high-speed moving machinery.
When choosing a reduction gear, it’s important to look for models with multiple teeth. Ideally, it will have more teeth than the corresponding sprocket. This will reduce the noise produced by the gears. The maximum number of teeth of the worm gear should be greater than 40.
Worm gears produce less noise and vibration than conventional gears. Also, they are cheaper and smaller than other types of reduction gears. However, worm gears have some limitations that make them less efficient than other types. For example, they do not perform as efficiently as parallel or orthogonal axes, which are much better at transmitting power.
The main disadvantage of worm gears is the difficulty of lubrication. Worm gear reducer gearboxes require more lubrication due to the helical motion of the gears. This means it is less efficient and more prone to wear than a standard gearbox. Helical motion has problems transmitting power and causes sliding friction, also known as sliding wear.
A worm reducer gearbox is a reduction gearbox used to decelerate a high-speed motor to a low-speed output. Worm gear reducer gearboxes produce lower output speeds while maintaining high torque. Its gears are made of bronze or stainless steel and have a right-angle output. The gears are very small compared to other reducer gearboxes, so they can be used in tight spaces and applications where space is limited.

Worm gear reducer gearboxes are an excellent choice for applications requiring high torque and low speeds. These reducer gearboxes are compact, durable and have a long service life. These gearboxes are also compatible with solid and hollow output shafts. This feature eliminates the need for chains or belts, reducing the number of moving parts. Plus, they’re easy to maintain, which means they’re an excellent choice for a variety of applications.
Worm gear reducer gearboxes are also compact, versatile and easy to install. The worm gear itself is made from a single piece of alloy steel. It has a high helix angle and is case hardened and ground for durability. Its six AF hex sockets are designed for easy installation and a wide range of ratios. Worm gear reducer gearboxes are also suitable for manual operation. They are easy to install, compact in design and compatible with a wide range of motors and drives.
Worm reducer gearboxes are often used in industrial settings where a small amount of torque is required to move large objects. They are also useful when space is at a premium. They are compact and easy to install in tight spaces. Worm gears reduce the risk of tripping and are often made of durable materials, making them a popular choice.
Compared with planetary gearboxes, worm gear reducer gearboxes have many advantages. They are quiet, produce less noise, and are more comfortable to use. They are also more energy efficient than their planetary counterparts. Furthermore, they can be combined with other gearboxes and trains to increase their output efficiency.

It is high efficiency

When a worm reducer gearbox is used in a gear-motor, it is critical to note that it is extremely high in efficiency. This type of reducer gearbox is typically much hotter than a hypoid reducer gearbox, which reduces the service life of the gear. The increased thermal stress on the sliding gears results in premature seal wear and leakage. Furthermore, excessive heat causes lubrication to break down and can cause contamination. Helical gear reducer gearboxes are significantly cooler and have a low-maintenance design. Consequently, they can reduce factory downtime and energy costs.
A servo-worm reducer gearbox is an excellent choice for applications requiring high performance, repeatability, and precision positioning. These gear reducer gearboxes have been specifically designed for use with servo motor technology, which provides tight integration of the gear motor. Other advantages of a servo-worm reducer gearbox include reduced angular backlash and longer life.
Hypoid gearmotors offer increased efficiency and allow smaller motors to be used. A 1 HP worm reducer gearbox can produce the same amount of output as a 1/2 HP hypoid reducer gearbox. A Agknx study compared the two types of reducer gearboxes, comparing power, torque, and efficiency. As a result, a 1/2 HP hypoid gearmotor is much cheaper to operate than a 1 HP worm reducer gearbox.
The efficiency of a worm gear reducer gearbox depends on many factors, including the mesh of the gears and losses in the bearings and oil seal lips. The speed and load of the reducer gearbox also have an impact on its efficiency. As a result, worm gear reducer gearboxes should be used with the right type of lubricant.
In a worm gear reducer gearbox, a non-intersecting shaft rotates against a gear, while the output worm gear rotates in a perpendicular direction. This arrangement produces high efficiency while reducing the noise and vibration of the gear motor. This gear reducer gearbox is also quiet and has a low friction coefficient.

It has a low clearance

Worm reducer gearboxes are typically designed with a low clearance, meaning that the worm is not allowed to touch the wheels in the gear arrangement. The lubricant used depends on the size of the gearing, and it is usually ISO 680 or ISO 460. Higher viscosities require special equipment.
Worm gears are popular in machines that need to stop quickly, such as lifts and elevators. The gears and worm are made of a soft material, minimizing backlash and failure rates. They are also popular in heavy-duty machines, such as rock crushers. But while this is an important aspect of their design, there are other factors to consider when choosing a worm gear.
Worm gears have multiple teeth, which allows for greater surface area contact and a better distribution of load. This feature allows for high transmission ratios without sacrificing power. Worm gears can be paired with other gearboxes to increase the overall efficiency of the system.
Worm gears are often used in heavy machinery, including trucks barreling down a deserted highway. They can also be found in packaging machinery, conveyors, and other small machinery. Their unique shape makes them ideal for tight spaces. But they also tend to wear and tear much faster than conventional gears.

It has a high torque to weight ratio

The worm gear reducer gearbox is a versatile gear train that provides a high torque-to-weight ratio. These reducer gearboxes are typically used in applications that require high torque and high gear ratios, such as machine tools. They also have a very compact design, enabling very high gear ratios at low speeds.
Worm gear reducer gearboxes are very quiet, mainly because the input and output shafts are perpendicular to each other. Their low noise level is an advantage compared to planetary gearboxes. Compared with planetary reducer gearboxes, worm gear reducer gearboxes are also relatively cheap.
The worm gear consists of two parts: the helical butt-jointed worm gear and the worm. The screw-butted worm gear is connected to the shaft by a helical thread. The worm gear is a variation of the six-simple machine. The worm is located in the worm wheel, which forces the worm to rotate. It also changes the plane of motion. Worm gears are usually made of steel or brass.
Worm gear reducer gearboxes are one of the most popular types of reducer gearboxes. It provides high torque and high speed ratio in a compact package. These reducer gearboxes are used in many power transmission systems, including elevators, safety gates, conveyor belts, and medical testing equipment.
Worm reducer gearboxes come in a variety of shapes and sizes, including parallel shaft reducer gearboxes and planetary worm reducer gearboxes. They have a high torque-to-weight ratio and are easy to maintain. They are also lightweight and relatively easy to install. This makes them an excellent choice for many applications.
Worms can be assembled using stepped shafts, set screws or dowel pins. However, the worm is subject to a lot of thrust and must be held firmly. This could lead to a rebound. Also, the bearings may come loose and the worm may move. To avoid backlash, make sure the worm gear shaft passes through the midpoint of the worm face width.
