FIELD: transport. ^ SUBSTANCE: gear mechanism comprises rod with outer thread, coupling fitted on said rod and coupling revolution drive appliances. Coupling has chamfer made on thread start and constant-diametre section with axial length corresponding to, at least, one thread. Chamfer features conical surface with rotation symmetry about coupling central axis. Said conical surface and central axis make angle varying from 2 to 35, preferably, from 5 to 15. ^ EFFECT: reduced vibration in mechanism. ^ 10 cl, 4 dwg |
