| titleOfInvention | Drive mechanism and drug delivery device having drive mechanism |
| abstract | The present invention relates to a drive mechanism suitable for injection devices, in particular pen-type drug delivery devices, and to such drug delivery devices. The mechanism connects the driven member (120) that can be driven by a spring, the driven member (40) that can be rotated, and the driven member (40) and the driving member (120) in a connected state in the rotational direction. The clutches (41, 121) and the clutches (41, 121), which enable the relative rotation in the clockwise and counterclockwise directions of the driven member (40) and the driving member (120) in the decoupling state, are brought into the connected state. A spring that allows relative axial movement of the driven member (40) and the driven member (40) that urges and decouples the clutch (41, 121) against the bias of the spring (130) (130). The clutch includes a first ring of crown teeth (121) of the drive member (120) and a second ring of corresponding crown teeth (41) of the driven member (40), each crown tooth (41, 121) have different ramp tooth angles in the clockwise and counterclockwise directions, and the teeth (41, 121) can ride on each other with different resistances in the clockwise and counterclockwise directions in the decoupled state of the clutch. It is like that. The material of the driving member (120) may be polybutylene terephthalate (PBT) or polyoxymethylene (POM), and the material of the rotatable driven member (40) is PBT, POM, or polycarbonate (PC). It may be. Further, the coefficient of friction (μ) between the teeth (41, 121) may be 0.07 to 0.13, and the teeth (41, 121) have a surface roughness (Ra) of 0.5 to 1.2. You may have. |
