Assembly containing two micromechanical parts

Abstract

To facilitate the manufacturing of assemblies containing micromechanical components. [Solution] The present invention relates to an assembly (10) comprising a first part (11) and a second part (20) which are micromechanical parts that engage with each other, wherein the first part (11) comprises a plate (12) from which a connecting member (13) formed by a projection extends, the projection having at least one radial step portion (130) that forms a rotating surface and at least one axial step portion (131) formed by a radially extending shoulder portion (132) that causes an allowable deviation in the plate (12), the connecting member (13) in the first part (11) pivots and engages with a complementary connecting member (21) in the second part (20) so that the second part (20) is pressed against the axial step portion (131) and the radial step portion (130).

Claims

1. An assembly (10) comprising a first part (11) and a second part (20), which are micromechanical parts that engage with each other, The first component (11) includes a plate (12), and a connecting member (13) formed by a projection extends from this plate (12), The protruding body has at least one radially stepped portion (130) that forms a rotating surface and at least one axially stepped portion (131) formed by a radially extending shoulder portion (132) that causes an allowable deviation in the plate (12). The connecting member (13) of the first part (11) pivots and engages with the complementary connecting member (21) of the second part (20), thereby pressing the second part (20) against the axial stepped portion (131) and the radial stepped portion (130). The connecting member (13) has at least one axial groove (133) that reduces the contact surface between the first part (11) and the second part (20), The groove (133) is formed between a distal end that opens at the free end of the connecting member (13) and a proximal end that reaches the axial step portion (131) or one of the axial step portions (131). Assembly (10).

2. The connecting member (13) has at least three radially stepped portions separated from each other by equally spaced grooves (133), so that the radially stepped portions extend over substantially the same angular sections. The assembly (10) according to claim 1.

3. The radial stepped portion (130) or one of the radial stepped portions is elastically deformable in the radial direction. The radial stepped portion (130) deforms when the connecting member (13) engages with the complementary connecting member (21) in the second part. The assembly (10) according to claim 1.

4. The deformable radial stepped portion (130) is formed by an elastic blade (134) extending along the curve. The assembly (10) according to claim 1.

5. The elastic blade (134) is configured to extend radially to the outside of the rotating surface. The assembly (10) according to claim 4.
