High Quality Chain Expansion for Roller Conveyor

A chain tensioner is a device used to adjust and maintain the tension of a chain. It usually consists of a tensioning wheel and a tensioning screw. The chain will relax during operation due to the increase of use time or the influence of external factors, and it is necessary to use the chain tensioner to adjust the tension of the chain to ensure the normal operation and service life of the chain.

product advantage


Chain tensioners have the following product advantages:

1. Adjust chain tension: Chain tensioning sleeves can help adjust the tension of the chain to ensure that the chain maintains proper tension during operation. This helps to increase the transmission efficiency and service life of the chain.

2. Reduce chain slack: The chain will cause transmission instability due to wear and relaxation after a period of use, and even jump the chain. The chain tensioning sleeve can adjust the tension of the chain in time, reduce the slack of the chain, and maintain the stable operation of the chain.

3. Improve transmission efficiency: By maintaining proper chain tension, the chain tensioning sleeve can reduce the sliding and friction between the chain and the gear, improve the transmission efficiency and reduce energy consumption.

4 Enhanced safety: Loose chains are prone to chain skipping or causing danger, and the use of chain tensioners can reduce this risk and improve the safety and reliability of equipment.


technical parameters


The technical parameters of chain tensioners may vary depending on the specific model and manufacturer. Here are some common technical parameters of chain tensioners:

1. Tension: The tension force of the chain tensioner refers to the force exerted by the tensioner on the chain. It is usually expressed in units of newtons (N) or kilonewtons (kN).

2. Maximum tensioning stroke: The maximum tensioning stroke of the chain tensioner refers to the maximum range of the rotation of the tensioning screw, which is used to adjust the tension of the chain. It is usually expressed in millimeters (mm).

3. Material: The main material of the chain tensioner is usually metal, such as steel or cast iron. These materials have sufficient strength and durability to withstand the tension of the chain and the requirements of the working environment.

4. Size: The size of the chain tensioner depends on the type and size of the chain. Common dimensional parameters include the diameter of the tensioner, the length and diameter of the tensioning screw, etc.

5. Operating temperature range: The operating temperature range of the chain tensioner depends on the temperature resistance of the selected material. In general, chain tensioners are able to operate properly at ambient temperatures, but in special applications they may need to consider their ability to withstand high or low temperatures.

6. Protection level: The chain tensioner may have the characteristics of dustproof, waterproof or corrosion protection to adapt to different working environments and requirements.

Please note that the specific technical parameters should be selected according to the actual needs and the model of the chain tensioner. When selecting and using chain tensioners, it is recommended to refer to the product specifications and technical data provided by the manufacturer to obtain accurate technical parameters and performance information.


product usage


Chain tensioners are mainly used to adjust and maintain the tension of the chain, ensuring that the chain maintains proper tension during operation. It is widely used in various mechanical equipment and industrial fields, and the specific product uses include but are not limited to the following aspects:

1. Conveyor: The chain tensioner can be used to adjust and maintain the chain tension of the conveyor to ensure the normal transportation and transfer of materials.

2. Crane: The chain tensioner can be used to adjust and maintain the chain tension of the crane to ensure the safe operation of the crane and the stability of the load.

3. Metallurgical equipment: Chain tensioners can be used for chain transmission systems in metallurgical equipment, such as continuous casting machines, rolling mills, etc., to ensure the normal operation and transmission efficiency of the chain.

4. Mining equipment: Chain tensioners can be used in chain transmission systems in mining equipment, such as shearers, conveyors, etc., to ensure the stable operation and durability of the chain.

5. Food processing equipment: Chain tensioners can be used for chain drive systems in food processing equipment, such as baking ovens, ovens, etc., to ensure the hygiene and safety of the chain.

6. Machinery manufacturing: chain tensioners can be used in the chain transmission system of various mechanical equipment, such as textile machinery, printing machinery, etc., to ensure the normal operation and transmission efficiency of the chain.

The selection of the appropriate chain tensioner model and material needs to be selected according to the specific application needs and operating environment to ensure optimal performance and results.


Product Operation Guide


The product operating instructions for chain tensioners are as follows:

1. Determine the chain slack: First of all, you need to check the tension of the chain to determine whether adjustments and tensioning are required. The tightness of the chain can be felt by pulling it manually.

2. Positioning tensioner: According to the position of the chain and the part that needs to be adjusted, determine the appropriate position to install the chain tensioner. The tensioner is usually mounted above the chain for easy adjustment and maintenance.

3. Install the tensioner: Install the chain tensioner in the appropriate position to ensure that it is in close contact with the chain. Use bolts or other fixtures to hold the tensioner in place.

4. Adjust the tension screw: Using the appropriate tools, rotate the tension screw to adjust the tension of the chain. Rotating the screw clockwise increases the tension of the chain, and rotating the screw counterclockwise reduces the tension of the chain.

5. Check the tension: After adjusting the chain tension, check the tension of the chain again. The tension of the chain can be felt by pulling it manually, ensuring that the chain is within the proper tension range.

6. Fixed tensioner: After completing the adjustment, ensure the position of the chain tensioner and the tightness of the fixture. If necessary, it can be tightened using tools such as a wrench or wrench.

Please note that the exact procedure may vary depending on the chain tensioner model and manufacturer. Before operating the chain tensioner, it is recommended to refer to the product manual or consult the manufacturer for accurate operating instructions.


FAQ and answer


Problem 1: The chain tensioner cannot adjust the tension of the chain.

Solution: First check whether the chain tensioner is installed correctly to ensure close contact with the chain. Then confirm that the tensioning screw rotates clockwise to increase tension or counterclockwise to reduce tension. If the problem persists, it may be necessary to inspect the tensioner's parts for damage or need to be replaced.

Problem 2: The chain is still loose after the chain tensioner adjustment.

Solution: Check the chain for wear or damage, if the chain has been excessively worn, it may be necessary to replace it with a new one. Also, check that the fixture of the tensioner is tightened to ensure that its position is stable

Problem 3: The chain tensioner makes an abnormal noise.

Solution: The noise may be caused by friction or loosening between the tensioner components. First check whether the fixture of the tensioner is tightened, and then check whether the parts of the tensioner are worn or need lubrication. If necessary, appropriate lubricants can be added.
