Abstract
The invention discloses a vibration attenuation bolt which comprises a bolt body, wherein a U-shaped groove is formed inside the bolt body, the U-shaped groove is filled with vibration attenuation materials, a plug is arranged on the bottom end of U-shaped groove, the vibration attenuation materials are polyurethane soft materials, and the plug is a rubber plug. Because the U-shaped groove is formed inside the bolt body and the U-shaped groove is filled with the vibration attenuation materials, the vibration attenuation bolt is strong in elasticity and absorbing capacity of vibratory force, reduces screw thread abrasion caused by mechanical vibration, prevents looseness, and improves mechanical working performance and working stability.
Description
Technical field
The present invention relates to a kind of bolt, particularly a kind of damping bolt, belong to the mechanical parts technical field.
Background technique
Bolt is used for being fastenedly connected two with the mechanical parts of through hole by head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, belongs to standard piece.As bolt is screwed out, can make again these two parts separately, be to belong to removably connect therefore 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, service behaviour and the working stability of impact machinery.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: having proposed a kind of energy increases the service behaviour of machinery and the damping bolt of working stability.
Technical solution of the present invention is achieved in that a kind of damping bolt, comprises bolt body, has U-shaped groove in described bolt body; Be filled with damping material in described U-shaped groove; The end of described U-shaped groove is provided with stopper.
Preferably, described damping material is the soft material of polyurethane.
Preferably, described stopper is rubber stopper.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Damping bolt of the present invention owing to having U-shaped groove in bolt body, is filled with damping material in U-shaped groove, elasticity is strong, and is strong to the absorptivity of vibration force, reduced the thread abrasion that causes because of mechanical vibration, prevent the generation of loosening phenomenon, increased mechanical service behaviour and working stability.
Description of drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the stereogram of damping bolt of the present invention;
Accompanying drawing 2 is damping bolt structural representation of the present invention;
Wherein: 1, bolt body; 2, U-shaped groove; 3, damping material; 4, stopper.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Be depicted as a kind of damping bolt of the present invention as accompanying drawing 1,2, comprise bolt body 1, have U-shaped groove 2 in described bolt body 1; Be filled with damping material 3 in described U-shaped groove 2; The end of described U-shaped groove 2 is provided with stopper 4; Described damping material 3 is the soft material of polyurethane; Described stopper 4 is rubber stopper.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Damping bolt of the present invention owing to having U-shaped groove in bolt body, is filled with damping material in U-shaped groove, elasticity is strong, and is strong to the absorptivity of vibration force, reduced the thread abrasion that causes because of mechanical vibration, prevent the generation of loosening phenomenon, increased mechanical service behaviour and working stability.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow person skilled in the art scholar can understand content of the present invention and be implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
