K-SPRINGS“ K”形碟形彈簧
“ K”形碟形彈簧的一個(gè)重要優(yōu)點(diǎn)是其形狀簡單的環(huán)。 這樣可以確保它們施加在軸承上的負(fù)載均勻地分布在軸承套圈上。
通過以交替方向（單個(gè)系列）布置彈簧，可以在恒定負(fù)載下提供額外的運(yùn)動。
相反，當(dāng)彈簧布置成面向相同方向（平行堆疊）時(shí)，可以在恒定彈簧撓度下施加附加載荷。
K-Springs碟形彈簧的優(yōu)點(diǎn)：
可以適應(yīng)裝配中建立的公差，而無需改變預(yù)緊力。
可以適應(yīng)通過差分?jǐn)U展產(chǎn)生的長度變化。 組件的任何后續(xù)軸向移動都不會顯著改變預(yù)緊力。
除了消除原始軸向游隙之外，這些還有其他優(yōu)點(diǎn)。
Smooth & Noise-free
Ball bearings run smoothly and noise-free when pre-loaded with our Original SCHNORR® “K” disc springs. They are available in slotted and non-slotted versions for bearings up to a diameter of 360 mm. Depending on the purpose for which they are used one or more disc springs may be specified.
Since in particular cases the inner ring rather than the outer ring of the ball bearing should be preloaded, all “K” disc springs are designed such that the outer diameter suitable for one size of bearing will also fit the inner diameter of another size of bearing. For example, a “K” disc spring which is designed for preloading the outer ring of a size 6302 bearing, can also be used to preload the inner ring of a size 6205 or 6305.
The use of “K” disc springs has important advantages.
An important advantage of “K” disc springs is their shape of a simple ring. This ensures that the load which they apply to the bearing is distributed evenly around the bearing ring. Additional movement at constant load can be provided by arranging the springs in alternate direction (single series). Conversely, additional load can be applied at constant spring deflection when springs are arranged to face the same direction (parallel stacking).
As all springs are designed to have a highly regressive characteristic large (ho/t) spring load remains nearly constant for large spring deflection.
Advantages of K-Springs:
- The tolerances built up in the assembly can be accommodated without significant change in preload.
- Length variations through differential expansion can be accommodated. Any subsequent axial movement of the assembly does not alter the preload significantly.
- These are further advantages in addition to the elimination of original axial play.
