Although the circlip can be used in most working conditions, with the update of technology, the special application of circlip has entered our vision, such as self-locking circlip. All circlips of the rotating shaft will be restrained by centrifugal force. If these centrifugal forces are large enough to expand the circlip so that it is no longer close to the groove, the function of the circlip will be reduced and it is likely to cause failure.
However, with the progress of science and technology and the renewal of equipment, more and more applications need to use higher rotation capacity, so the centrifugal force of the circlip will be greater and greater. If your application requirements exceed the recommended rotation capacity indicated by the standard circlip, you can choose according to the specific application requirements. Because the rotation capacity is a function of many parameters (i.e. thickness, radial wall size, degree of fit, interference fit, diameter between retaining ring and groove, etc.), The rotation ability can be improved by increasing the size of the radial wall and / or the fit between the retaining ring and the groove.
If your application requirements exceed the recommended rotation capacity of the standard retaining ring, you can select the self-locking retaining ring according to the application requirements. The self-locking retaining ring is used for ultra-high speed working conditions, and its self-locking structure can overcome the centrifugal force at high speed. The self-locking snap ring is a custom snap ring. The self-locking function is realized by protrusion and groove, which can be interlocked to prevent the expansion of snap ring. The protrusion fits perfectly with the groove on the fitting ring, so when the snap ring is installed in the groove, the protrusion will clamp in the groove. This function enables the retaining ring to operate normally at a speed far exceeding the rotation capacity of the standard circlip. Therefore, this self-locking function enables the retaining ring to run at high speed, bear vibration, accelerate operation, and absorb a certain degree of impact load at the same time.
Installation method of self-locking retaining ring
The installation process of the self-locking circlip is roughly the same as that of the standard circlip, but it is one step more than the standard circlip, that is, the protrusion of the self-locking circlip needs to be knocked into the groove with a small hammer or wooden mallet to achieve accurate positioning. The two protrusions of the self-locking snap ring must be completely fixed in the corresponding grooves of the mating ring.
