Description
Technical Field
The utility model belongs to the technical field of fasteners, and relates to a nut gasket, in particular to a novel nut anti-loose combined gasket.
Background
Bolts and nuts are commonly used fasteners for fastening two parts with through holes, and the bolts and nuts are usually provided with a gasket, which is usually a part arranged between the connected member and the nut, and is a generally flat metal ring for protecting the surface of the connected member from being scratched by the nut and dispersing the pressure of the nut against the connected member.
In some fastening occasions with large vibration, the locking function of the connection of the bolt and the nut needs to be enhanced to prevent the nut from loosening, usually, a check gasket is used, and the check effect of the existing check gasket is not obvious for the connection position with continuous vibration or large vibration; sometimes, the connection is strengthened by adopting a double-nut mode, but the loosening can also be generated due to long-time vibration, for example, a bolt fixing nut of a TBM cutter is large in vibration of a cutter head, a spare nut used for preventing the locking nut is firstly loosened, and then the locking nut is also loosened.
In order to solve the problems, the novel anti-loose combined gasket for the nut is designed, so that the locking nut and the spare nut can be effectively prevented from rotating relatively, and then the anti-loose purpose is achieved.
SUMMERY OF THE UTILITY MODEL
