FIELD: machine building. ^ SUBSTANCE: device for securing assembly part (23) and bearing part (24) remote one from another consists of assembly nut (1) with internal thread (9) with first direction of thread, of compensating bushing (5) with external thread (8) matching internal thread (9) of assembly nut (1) and of fastening screw (26). Also rod (25) of the screw has external thread (27) with the second direction of thread opposite to the first direction of thread. Compensating bushing (5) has internal sleeve (13). Reinforcing zones (17) and adaptive zones (18) are alternately arranged in upper section (15) of the sleeve. Additionally, reinforcing zones (17) possess higher resistance to expansion directed radially outside, than adaptive zones (18). ^ EFFECT: comparatively low torque at tightening and wide choice of materials for fastening screw and compensating bushing at sufficiently large allowances between diametres of sections of channel of compensating nut and screw rod. ^ 7 cl, 4 dwg |
