FIELD: machine building. ^ SUBSTANCE: central axis 73 is installed in centre of fixing and bearing component 71 in rotation damper. Driven to rotation component 61 has internal cylinder wall 63, inside of which there is introduced relatively rotating central axis 73. Packing ring 81 is installed between central axis 73 and internal side surface of internal cylinder wall 63. The ring prevents leakage of viscous fluid medium 101 from zone between driven to rotation component 61 and fixing and bearing component 71. First channel 70 is made in driven to rotation component 61. The channel communicates receiving section 91 with ambient space. Also, there is made orifice 63 communicating the zone at a lower side of packing ring 81 inside receiving section 91 with first channel 70. According to the second version the damper first 61 and second 71 components has a channel communicating receiving section 91 with a closed zone. Additionally, there is a narrow spot in the channel. ^ EFFECT: facilitation of assembly process and reduced non-uniformity of damping moment of twisting. ^ 8 cl, 25 dwg |
