GAP COMPENSATION DEVICE FOR AUTOMATIC GAP COMPENSATION BETWEEN TWO COMPONENTS Russian patent published in 2024 - IPC F16B5/02 

FIELD: machine building.

SUBSTANCE: device comprises a bolt with an external thread of a first direction, intended for installation in through holes of the first and second components with the possibility of resting with its head against the first component on the side of its outer surface, compensating bushing has on the cylindrical side wall the first connecting part made in the form of external thread of the second direction interacting with internal thread of the same second direction of the nut intended for rigid connection with the second component. Compensating bushing is made with the second connecting friction part interacting with the external thread of the first direction of the bolt. Cylindrical side wall of the compensating bushing is made integral. Second connecting friction part of the compensating bushing is internal thread of the first direction made on the inner surface of its cylindrical side wall and interacting in the threaded connection with the external thread of the first direction of the bolt with guaranteed tightness. On external thread of the first direction of bolt there is an annular female section of solidified layer of sealant.

EFFECT: simpler design of the device and, as a result, simpler technology of its manufacturing, as well as the possibility of using the same simplified design of the device in similar type-sized devices.
