Description
Technical field
The present invention relates to Screen device technical field, particularly to a kind of double damping couple vibroshocks.
Background technology
At present, the vibration isolator that vibrosieve is used is mainly metal helical spring, it is impossible to provide damping.During so vibrosieve starts or docking process passes through resonance region, vibrosieve amplitude is relatively big, affects life-span and the stability on basis of vibrosieve parts.Some other method must be taked to suppress amplitude for this manufacturer, make vibrosieve cost high；The vibration isolator that vibrosieve is used also has employing rubber cylinder as vibration isolator, but the damping that during vibrosieve resonance, it can be provided by is limited, and when vibrosieve normally works, it provides bigger damping consumed energy, so rubber cylinder vibration isolator is few.
Summary of the invention
For the deficiencies in the prior art, the present invention provides a kind of double damping couple vibroshock.
The present invention be the technical scheme is that this vibroshock includes circular cone composite spring shock absorber, rubber bar ring vibroshock, top cover and base plate for achieving the above object, wherein circular cone composite spring shock absorber is pyramid type core structure, circular cone composite spring shock absorber upper end is provided with top cover, lower end is provided with base plate, and rubber bar ring vibroshock is placed in circular cone composite spring shock absorber inside and is fixed under top cover.
Described circular cone composite spring shock absorber includes metal conical helical spring and rubber conical helical spring；Metal conical helical spring is combined into one through sulfuration with rubber conical helical spring.
Described rubber bar ring vibroshock includes cylindrical rubber damping rod, annular rubber damping ring, circular ring metal overhead gage, circular ring metal lower baffle plate and metallic cylinder；Wherein cylindrical rubber damping rod is cased with annular rubber damping ring, the outside of annular rubber damping ring connects the inwall of metallic cylinder, circular ring metal overhead gage is fixed on the top of metallic cylinder, circular ring metal lower baffle plate is arranged on the lower section of annular rubber damping ring, and being fixed on the inwall of metallic cylinder, metallic cylinder is fixed on base plate.
The invention have the advantage that the metal helical spring in prior art, or cylindrical rubber spring, the circular cone complex spring changing into being compounded to form through sulfuration with rubber conical helical spring by metal conical helical spring couples, with rubber bar ring vibroshock, the new type vibration isolator constituted---double damping couple vibroshocks.When vibrosieve normally works, vibration isolator does not provide damping, starts or docking process passes through but to be provided that bigger damping during resonance region, be only more satisfactory vibration isolator.Double damping couple vibroshocks, can only provide less damping when vibrosieve normally works, and start or docking process passes through but to be provided that bigger damping during resonance region, be more satisfactory vibration isolator.
Accompanying drawing explanation
Fig. 1 is the half sectional view of the double damping couple vibroshock of the present invention；
1 cylindrical rubber vibration damper bar, 2 first screws, 3 top covers, 4 second screws, 5 rubber conical helical springs, 6 metal conical helical springs, 7 circular ring metal overhead gages, 8 the 3rd screws, 9 annular rubber damping rings, 10 the 4th screws, 11 circular ring metal lower baffle plates, 12 the 5th screws, 13 metallic cylinder, 14 base plates in figure.
Detailed description of the invention
The detailed construction of the present invention is illustrated in connection with specific embodiments.
As it is shown in figure 1, this vibroshock includes circular cone composite spring shock absorber, rubber bar ring vibroshock, pushes up 3 lid and bottom plates 14, circular cone composite spring shock absorber is pyramid type hollow core structure, and rubber bar ring vibroshock is placed in inside circular cone composite spring shock absorber；Circular cone composite spring shock absorber includes metal conical helical spring 6 and rubber conical helical spring 5；Metal conical helical spring 6 is combined into one through sulfuration with rubber conical helical spring 5, rubber conical helical spring 5 is fixed on top cover 3 and base plate 14 by the second screw 4, and rubber bar ring vibroshock includes cylindrical rubber damping rod 1, annular rubber damping ring 9, circular ring metal overhead gage 7, circular ring metal lower baffle plate 11 and metallic cylinder 13；Wherein cylindrical rubber damping rod 1 is fixed on top cover 3 times by the first screw 2, cylindrical rubber damping rod 1 is cased with annular rubber damping ring 9, the outside of annular rubber damping ring 9 connects the inwall of metallic cylinder 13 by the 4th screw 10, circular ring metal overhead gage 7 is fixed on the top of metallic cylinder 13 by the 3rd screw 8, circular ring metal lower baffle plate 11 is arranged on the lower section of annular rubber damping ring 9, and being fixed on the inwall of metallic cylinder 13 by the 5th screw 12, metallic cylinder 13 is fixed on base plate 14.
The work process of the present invention: annular rubber damping ring 9 mid portion can only do limited vertical motion up and down between fixing circular ring metal overhead gage 7 and circular ring metal lower baffle plate 11.Cylindrical rubber vibration damper bar 1 is in close contact with annular rubber damping ring 9.When vibrosieve normally work the amplitude of up-down vibration less time, cylindrical rubber vibration damper bar 1 is up-down vibration together with the mid portion of annular rubber damping ring 9, and rubber bar ring vibroshock is the most inoperative；Due to have employed pressure and time metal conical helical spring 6 circle between centre-height be zero this special method for designing, when the amplitude that vibrosieve starting or docking process pass through resonance region up-down vibration is bigger, the rubber of rubber conical helical spring 5 produces shearing and extruding combined deformation simultaneously, bigger cutting can be produced and squeeze damping, cylindrical rubber vibration damper bar 1 will produce relative slip with the mid portion of annular rubber damping ring 9, and at this moment rubber bar ring vibroshock can produce bigger non-linear friction damping.Owing to cutting the coupling squeezing damping and frictional damping, the amplitude of vibrosieve can be played obvious inhibitory action.
