Abstract
The utility model relates to a vibration attenuation bolt, which comprises a bolt body, wherein a U-shaped slot is formed in the bolt body; a vibration attenuation material is filled in the U-shaped slot; a plug is arranged at the tail end of the U-shaped slot; the vibration attenuation material is a polyurethane flexible material; and the plug is a rubber plug. According to the vibration attenuation bolt, the U-shaped slot is formed in the bolt body, and the vibration attenuation material is filled in the U-shaped slot, so that the vibration attenuation bolt has high elasticity and high absorption capacity to vibration force; and therefore, threaded abrasion caused by mechanical vibration is reduced, a looseness phenomenon is avoided, and the working performance and the working stability of machinery are improved.
Description
Technical field
The utility model relates to a kind of bolt, and particularly a kind of vibration damping bolt belongs to the mechanical parts technical field.
Background technique
Bolt is used to be fastenedly connected two mechanical parts that have through hole by head and screw rod (having externally threaded cylindrical body) one type of fastening piece dimerous, belongs to standard piece.As screwing out bolt, can make these two parts separately again, be to belong to removably connect so bolt connects.But because some machinery can produce violent vibration in the process of day-to-day operation, cause screw thread to be worn, cause the loosening of bolt, the service behaviour and the working stability of influence machinery.
The model utility content
The utility model purpose is to provide a kind of can increase the service behaviour of machinery and the vibration damping bolt of working stability for the deficiency that overcomes existing technology.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of vibration damping bolt, comprise bolt body, and have U type groove in the said bolt body; Be filled with damping material in the said U type groove; The end of said U type groove is provided with stopper.
Preferably, said damping material is the soft material of polyurethane.
Preferably, said stopper is a rubber stopper.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The vibration damping bolt of the utility model; Owing to have U type groove in the bolt body, be filled with damping material in the U type groove, elasticity is strong; Absorptivity to vibration force is strong; Reduce the thread abrasion that causes because of mechanical vibration, prevented the generation of loosening phenomenon, increased mechanical service behaviour and working stability.
Description of drawings
Below in conjunction with accompanying drawing the utility model technological scheme is described further:
Accompanying drawing 1 is the stereogram of the vibration damping bolt of the utility model;
Accompanying drawing 2 is the vibration damping bolt arrangement schematic representation of the utility model;
Wherein: 1, bolt body; 2, U type groove; 3, damping material; 4, stopper.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The described a kind of vibration damping bolt of the utility model shown in accompanying drawing 1-2 comprises bolt body 1, has U type groove 2 in the said bolt body 1; Be filled with damping material 3 in the said U type groove 2; The end of said U type groove 2 is provided with stopper 4; Said damping material 3 is the soft material of polyurethane; Said stopper 4 is a rubber stopper.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The vibration damping bolt of the utility model; Owing to have U type groove in the bolt body, be filled with damping material in the U type groove, elasticity is strong; Absorptivity to vibration force is strong; Reduce the thread abrasion that causes because of mechanical vibration, prevented the generation of loosening phenomenon, increased mechanical service behaviour and working stability.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
