Abstract
The utility model discloses based on the damping device for improving damping effect, including pedestal, the upper end of the pedestal is vertically installed with lead, the outer wall of the lead is arranged with spring, and the spring one end is connected with pedestal, and the other end is connected with top plate, the top plate is set on lead, it is connected between the top plate and pedestal at least provided with 2 piston rods, the piston rod with hydraulic cylinder, the end of the pedestal and lead is both provided with retainer ring.The utility model by setting spring and piston rod simultaneously, when top plate is under pressure, the common flexible realization damping of spring and piston rod can avoid the problem that causing damping effect poor when spring deforms upon, the utility model has good damping effect.
Description
Technical field
The utility model is related to cushion technique fields, and in particular to based on the damping device for improving damping effect.
Background technology
The power set on stationary plant and naval vessel are mainly by internal combustion engine, shafting, propulsion device (such as ship propeller) structure
Into.Since the uneven excitation of internal combustion engine at work can cause shafting to generate twisting vibration and (be similar to the work of reciprocal stubborn fried dough twist
With), after torsional oscillation reaches a certain level, high vibration can occur for shafting, and shafting is caused to be broken so that device runs out of steam.For
The harm that torsional oscillation is brought to shafting is avoided, must just give shafting installation damper.
Damper mainly includes dynamic damper, damping shock absorber and composite damper, and damper is in actual use process
In frequently encounter damage or fracture, it is necessary to which on-call maintenance, loses reduction damping effect on one side.
Existing damper damping effect is poor.
Utility model content
The utility model be designed to provide based on improve damping effect damping device, solve existing damper
The problem of damping effect is poor.
The utility model is achieved through the following technical solutions：
Based on the damping device for improving damping effect, including pedestal, the upper end of the pedestal is vertically installed with lead, institute
The outer wall for stating lead is arranged with spring, and the spring one end is connected with pedestal, and the other end is connected with top plate, and the top plate is arranged
On lead, at least provided with 2 piston rods between the top plate and pedestal, the piston rod is connected with hydraulic cylinder, described
The end of pedestal and lead is both provided with retainer ring.
Piston rod described in the utility model, hydraulic cylinder are the prior art, and stretching for piston rod is realized under the control of hydraulic cylinder
Contracting, the retainer ring are used to be connected with joint outer part.
Existing damper usually relies only on spring and carries out damping, and after spring uses a period of time, deforming upon causes to subtract
It is poor to shake effect.
The operation principle of the utility model：It when top plate is under pressure, moves down, by pressure transmission to spring and piston
Bar passes through the common flexible realization damping of spring and piston rod.
The utility model by setting spring and piston rod simultaneously, when top plate is under pressure, spring and piston rod
Common flexible realization damping, can avoid the problem that causing damping effect poor when spring deforms upon, the utility model has very
Good damping effect.
Further, the outer sheath of piston rod is equipped with rubber sleeve.
The rubber sleeve plays an important role of noise reduction, can lower the noise generated when piston rod stretches.
Further, several compression springs are provided on spring, the spring is arranged between the spacing of spring.
The setting of the compression spring can avoid spring from being overly compressed, and compress spring also with certain bullet
Property can improve the damping effect of spring.
Further, the upper end on lead in top plate is provided with limiting plate.
The setting of the limiting plate can avoid spring from being excessively stretched.
Further, the trapezium structure of top plate.
Wherein, the one side being connected with spring and piston rod is the larger trapezoidal bottom surface of area, can improve top plate and spring
The stability connected with piston rod.
Further, it is provided with rubber washer in retainer ring.
Improve the stability that retainer ring is connected with joint outer part.
The utility model compared with prior art, has the following advantages and advantages：
The utility model by setting spring and piston rod simultaneously, when top plate is under pressure, spring and piston rod
Common flexible realization damping, can avoid the problem that causing damping effect poor when spring deforms upon, the utility model has very
Good damping effect.
