Description
Technical field
The utility model relates to vibration damper field, particularly a kind of vibration damper that intersects.
Background technique
Vibration damper, since generation, with the structure of its uniqueness and effect, has been widely used in the systems such as Aeronautics and Astronautics, naval vessel, machinery.Generally be divided into spring damper, rubber absorbers, damping shock absorber etc.
The consequence that great majority vibration produces is all harmful, and in order to reduce the detrimental consequences vibrating and bring, just need a kind of carrier to isolate or reduce the harm that vibration produces, this carrier is just called vibration damper.Concussion when vibration damper rebounds after being mainly used to suppress spring shock-absorbing and the impact from road surface.Through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is just used to suppress this spring to jump.Vibration damper is too soft will vertical bounce, and vibration damper will bring too large resistance too firmly, hinders spring normally to work.
In prior art, vibration damper is mostly the combination of rubber product or metal and rubber product, although damping effect is good, they also expose a lot of shortcoming while playing damping.As vibration damper itself exists self-vibration, and damping is too little, poor for the isolating technique ability near resonant frequency; Rubber absorbers are subject to the restriction of material own, easily aging, and free frequency is relatively high, and compressibility is less, unstable properties, and working life is shorter.The deficiency of damping shock absorber is that oil sealing requires height, complex process, not easy-maintaining, when cylinder barrel changes by extraneous greater impact, then can not work.General vibration damper positioning precision is poor, complex structure.
Model utility content
The purpose of this utility model is to provide a kind of intersection vibration damper that can solve the deficiencies in the prior art, have employed more reasonable and ingenious structure.
The technical solution adopted in the utility model is:
Intersection vibration damper, comprise supporting portion and guide mechanism, it is characterized in that: the guide cylinder of described guide mechanism, guide cylinder lower end seals, upper end has been threaded connection gland, the upper end oral area of guide cylinder is provided with guide sleeve, guide sleeve is fixed on the upper end of guide cylinder by gland, the middle part of guide sleeve and gland is provided with bores a hole and is slidably fitted with piston rod, the lower end of piston rod is installed with the piston being slidably mounted on guide cylinder inwall by nut and spring pad, upper cover of piston rod between piston and guide sleeve has spring, this both ends of the spring is fixedly connected on piston and guide sleeve respectively, the upper end of piston rod is installed with lower bracket, upper cover of piston rod between the lower end of lower bracket and gland upper end has spring, this both ends of the spring is fixedly connected on lower bracket and gland respectively,
Supporting portion comprises upper and lower bracket, and the both sides of upper and lower bracket are provided with hypotenuse and are provided with one group of pressing plate and screw also, respectively, and for fixing two dunnages arranged in a crossed manner, the two ends of two dunnages are individually fixed on the hypotenuse of upper and lower bracket both sides.
Described intersection vibration damper, is characterized in that: described piston is provided with some perforation and through there being piston to follow closely, the two ends of piston nail are equipped with buffer gasket.
Described intersection vibration damper, is characterized in that: be provided with circular groove between described gland and guide sleeve and be provided with felt seal ring and to be tightly connected piston rod.
Compared with prior art, the beneficial effects of the utility model are:
The utility model in use effectively can solve the little problem of self-vibration, damping that common vibration damper self exists, and solve rubber absorbers easily aging, free frequency is relatively high, compressibility is less, unstable properties, the problem that working life is shorter, etc.; The utility model is easily manufactured, easy care maintenance, and while obtaining satisfactory damping effect, can obtain the positioning precision of high precision, this is that general vibration damper is unexistent.
