The inclusion of slots on either the inner or outer diameter creates a lever that works on the un-slotted portion of the slotted disc spring. This effect reduces the spring load and increases the deflection, giving the spring a softer characteristic with larger deflection, in proportion to the outside diameter smaller spring loads.
With this type of spring, it is most important that the permissible stresses in the annular portion are not exceeded. If necessary, the outside diameter must be increased to compensate.
CAD files for stock and standard slotted disc springs are available in our online store.
Slotted Disc Springs Overview
This spring is configured with slotted elements which reduce the spring load and increase deflection. Other benefits of slotted disc springs include:
- Generates very small loads.
- Accommodates large deflections
- Achieves quiet-run bearing assembly
- Accommodates the build up of tolerances within assembly
- Eliminates thermal movements
Custom Slotted Disc Springs
All our disc springs are subject to exacting manufacturing and quality control standards. All discs are preset so that they will not significantly relax under load over time. MW also offers pre-stressed disc springs specifically sized for use with bolts.
