K-SPRINGS“ K”形碟形弹簧
“ K”形碟形弹簧的一个重要优点是其形状简单的环。 这样可以确保它们施加在轴承上的负载均匀地分布在轴承套圈上。
通过以交替方向（单个系列）布置弹簧，可以在恒定负载下提供额外的运动。
相反，当弹簧布置成面向相同方向（平行堆叠）时，可以在恒定弹簧挠度下施加附加载荷。
K-Springs碟形弹簧的优点：
可以适应装配中建立的公差，而无需改变预紧力。
可以适应通过差分扩展产生的长度变化。 组件的任何后续轴向移动都不会显着改变预紧力。
除了消除原始轴向游隙之外，这些还有其他优点。
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.
