Answer
Nested wave springs consist of multiple turns coiled in parallel to increase the load capacity without increasing the footprint. The primary assembly challenge is maintaining the 'alignment' of the waves. If the turns shift or become misaligned during installation, the waves will not nest perfectly, causing a 'stacked' condition that leads to an unpredictable, non-linear spring rate and potential localized yielding. In a clutch pack, this misalignment can cause uneven pressure on the friction plates, leading to premature wear or clutch chatter. Assembly must often utilize a precision pilot tool or a keyed internal diameter to ensure the nested layers remain synchronized during the compression into the housing.
