The ratchet tensioner is a tightening tool for the tensioner and also a type of chain tensioner, which locks the chain through the ratchet action. It is mainly used to realize stepless speed change and positioning functions in mechanical transmission systems. At the same time, it also plays an important role in cargo transportation, heavy cargo operation, movement, shipping or warehousing.
2. Structure and working principle
Structure: The ratchet tensioner mainly consists of a circular or convex ratchet and an adjustable lever.
Working principle: When the lever moves forward, the ratchet teeth of the ratchet contact the link part of the chain and pull the chain forward. When the lever moves backward, the chain will relax. The function of the ratchet tensioner is to ensure that the chain always maintains the correct tension during normal operation.
3. Product features
High strength and durability: The ratchet tensioner adopts a cast steel structure, which is strong and durable and can withstand high workloads.
Adjustment function: It has a unique quick adjustment function, which can quickly adjust the tightening, extension and free rotation according to different needs to meet the use needs under various road conditions and weather conditions.
Closed ratchet gearbox: The ratchet tensioner is equipped with a closed ratchet gearbox, which ensures the smooth operation and protection of internal parts, prevents external factors from damaging the gearbox, and prolongs the service life of the product.
Convenient operation: The hook can rotate 360°, which is easy to operate and easy to carry.
Space saving: The ratchet tensioner has a compact structure and occupies little space, which is suitable for occasions with limited space.
IV. Application scenarios
Ratchet tensioners are widely used in various equipment and occasions, such as machine tools, printing presses, fans, cranes and other equipment that require the installation of brake devices, and are also used in modern industrial fields such as automated production lines, CNC machine tools, and handling robots. In terms of road freight, ratchet tensioners provide stable protection for cargo transportation, whether it is a flat road or a bumpy mountain road, it can ensure that the goods are delivered to the destination safely and intact.
V. Maintenance and care
The maintenance of the ratchet tensioner is very convenient, and only regular cleaning and lubrication are required. At the same time, care should be taken to avoid excessive tightening or sudden release of the chain during use to avoid damage to the ratchet and chain.
