Definitions
- the ratio of said determined average height of said asperities and of the sum of said thickness of said flat piece and of said determined average height of said asperities is between one half and one tenth, while said determined average height of said asperities is preferably comprised between 30 pm and 500 pm.
- the spacers are suitable for being implemented on any type of bearing surface.
- the height of these asperities can be predetermined depending on the type of mechanical component to be assembled.
- friction spacers are used, the roughnesses of which have a length close to 300 ⁇ m.
- friction spacers are used with roughness whose length is close to 50 ⁇ m.
- the friction spacer then obtained after the micromachining comprises a flat part 20 and the asperities 16 which project from the surface 18 of the flat part 20.
- the height h of the asperities 16 of 75 ⁇ m is to be related to the thickness e of the raw flat annular part 10, but also to the distance which extends from the face 14 opposite to the machined face 12, up to the top of the asperities 16 and which is 300 pm.
- This ratio is on the example presented here of a quarter, in other words, of 0.25.
