Role of guk lock nut
RN square guk lock nut
is mainly used in connection scenarios that require stable clamping and anti-rotation. Its square structure facilitates the wrench to apply force in a narrow space, ensuring reliable tightening in space-restricted areas such as internal cavities of equipment and compact mechanical structures; at the same time, the larger side contact area can enhance the friction with the connected parts, effectively preventing the nut from rotating with the bolts in low-frequency vibration environments, such as furniture assembling, light machinery fixing, etc., to ensure the long-term stability of the connection part and avoid the displacement of the parts or functional failures caused by loosening. Functional failure is avoided. In addition, the symmetry of the square structure eliminates the need to deliberately align the angles during installation, which speeds up assembly, and is especially suitable for standardized installation processes in mass production.
The F-type guk lock nut
is suitable for connection fixings subject to shocks and vibrations. Through the special design of asymmetric tooth shape, when tightened with the bolt tooth belly to form a close wedge contact, resulting in sustained friction, even in high-frequency impact scenarios such as automobile chassis suspension system, machine tool transmission components, etc., can prevent the threaded sub-loosening, to maintain the connection of the state of fastening, to protect the mating bolts from excessive wear to ensure the stable operation of the transmission system. Moreover, its teeth and belly contact mode can disperse the thread force, reduce local stress concentration, extend the overall service life of bolts and nuts, and reduce the cost of frequent replacement.
R type radial guk lock nut
is mainly used for fixing parts with frequent axial displacement. With the help of radial open groove structure, tighten the end of the screw, the groove shrinkage so that the inner diameter of the nut is reduced, and the bolt to form an interference fit, resulting in a stable radial clamping force. In the hydraulic piston rod, ball screw shaft end and other scenarios where there is axial runout, this radial force is not affected by axial displacement and can always maintain the rigidity of the connection, preventing parts from loosening or shifting during the movement process and ensuring the precise operation of the equipment. In addition, its radial locking method of the bolt straightness requirements are low, even if the bolt has a slight bend, can still realize the effective locking, enhance the degree of tolerance for installation errors.
Fourth, the K-type axial guk lock nut
is mostly used in connection parts with large temperature fluctuations or axial loads. Its end face of the elastic retaining ring or embossed structure in the tightening of the axial elastic force, continuous action on the surface of the connected parts. In the engine compartment, high-temperature pipelines and other environments with obvious temperature changes, it can compensate for the loss of preload force due to thermal expansion and contraction, and maintain the close fit of the threaded sub; at the same time, in the unidirectional axial load scenarios, such as crane booms and press equipment sliders, it can stably withstand the axial force, prevent the nut from loosening, and safeguard the safety of the connection of heavy-duty components. Moreover, its elastic structure does not require excessive torque control during installation, which reduces the requirements for assembly tools and facilitates quick on-site operation.
