In one embodiment, the difference 5mm of the internal diameter of the ring body and outer diameter is between 10mm.
In one embodiment, between the both ends of the inner arc of the stress surface linear distance setting 3mm to 3.5mm it Between.
In one embodiment, between the both ends of the outer arc of the stress surface linear distance setting 4mm to 5mm it Between.
In one embodiment, the linear distance between the both ends of the inner arc of the folding surface is arranged in 0.7mm to 1.2mm Between.
In one embodiment, between the both ends of the outer arc of the folding surface linear distance setting 1mm to 1.5mm it Between.
In one embodiment, the thickness between the top of the wave crest and the bottom of the trough is arranged in 2mm to 3mm Between.
In one embodiment, the axial direction of the transition face and the ring body is arranged in set angle, angle It is set as between 95 ° to 105 °.
In one embodiment, the ring body uses elastic material integrated injection molding.
A kind of clothing care machine is also provided in the utility model embodiment, the clothing care machine uses above-mentioned any one Wave washer, the wave washer is assemblied between the belt and bearing of the clothing care machine.
By the utility model, solve in the prior art wave washer because opening design lead to asking for discontinuity Topic, can guarantee that wave washer when being squeezed, increases contact area, thus guarantee machine operation when it is more steady, make an uproar Sound is smaller, abrasion lightens, and extends the service life of such as bearing component, and can guarantee convenience when installation, greatly simplifies Packaging technology.
[Detailed description of the invention]
