FIELD: machine building.SUBSTANCE: support (7) of bearing includes front part (1) and rear part (2), which include many front holes (10) and rear holes (20), through which safety screws (3) pass. For all screws there provided is gap (4) between each front hole (10) and safety screw (3) passing through it, which allows avoiding any contact between front hole (10) and safety screw (3) due to the above gap. Front part (1) and rear part (2) of bearing support contact each other at least through two parallel surfaces of sides of different diameters, which form external and internal alignment means, form double alignment means, and interacting with each other to provide axial alignment of one of the above parts relative to the other part.EFFECT: providing better control of disconnecting function owing to eliminating shear forces on safety screw, and possibility of eliminating oval deformation of bearing support.6 cl, 10 dwg |
