Description
Technical field
The present invention relates to a kind of dampers, and in particular to arrive a kind of steel ball damper, belong to vibration and electrically with electromechanical skill
Art field.
Background technique
The equipments such as motor, diesel engine, steam turbine, blower during the work time, inevitably generate vibration, and vibration
Pass to installation foundation, while influencing the working performance of equipment, at present, it is common to use method be to add rubber pad or make
Damping is carried out with hydraulic damper, viscous damper, for hydraulic damper, viscous damper, needs to carry out regular
Maintenance work, and the service life of rubber pad is shorter.
Summary of the invention
In order to solve this problem, the invention proposes a kind of steel ball dampers.
Technical scheme is as follows:
A kind of steel ball damper, comprising: lower cover, cylinder, upper end cover, interior steel ball damper, steel ball；
The interior steel ball damper includes interior steel ball damper lower cover, interior steel ball shock absorber cylinder, interior steel ball shock absorber cylinder
Upper end cover, piston, piston rod；
The lower end of the interior steel ball shock absorber cylinder is reliably connected with the formation of interior steel ball damper lower cover, interior steel ball shock absorber cylinder
The upper end of body is reliably connected with the formation of interior steel ball damper upper end cover；
The piston and piston rod are reliably connected integrally, form piston component；
The piston is mounted in interior steel ball shock absorber cylinder body, and piston rod top is through interior steel ball damper upper end cover and from interior steel
It is stretched out in pearl damper upper end cover；
The piston is interior steel ball shock absorber cylinder inside division under working chamber A and interior steel ball damper on interior steel ball damper
Working chamber B two parts；
Fill full steel ball on the interior steel ball damper under working chamber A and interior steel ball damper in working chamber B；
The lower end of the cylinder is reliably connected with lower cover formation, and upper end and the upper end cover formation of cylinder are reliably connected；
The interior steel ball damper is mounted in cylinder, and piston rod top is stretched out through upper end cover and from upper end cover；
Inner barrel is divided into upper working chamber C and lower working chamber D two parts by the interior steel ball damper；
Circular passage is formed between the outer circle wall and cylinder inboard wall of the interior steel ball damper；
Full steel ball is filled in the upper working chamber C, lower working chamber D and circular passage；
The steel ball damper is installed on pedestal by the mounting hole on lower cover；The steel ball damper passes through on piston rod
End screw thread is connected with equipment.
Above-mentioned steel ball can diameter it is identical or diameter is different.
Beneficial effects of the present invention are as follows:
The present invention includes lower cover, cylinder, upper end cover, interior steel ball damper, steel ball；A kind of steel ball damper passes through on lower cover
Mounting hole be installed on pedestal, be connected by piston rod threaded upper ends with equipment, the upper working chamber of steel ball damper, lower work
Make chamber, be pre-charged with full steel ball in circular passage and in the working chamber up and down of interior steel ball damper, when steel ball damper works,
On the one hand, the steel ball in interior steel ball damper or more working chamber is squeezed by piston up-down and on the other hand passes through interior steel ball
The up and down motion of damper squeezes the steel ball in working chamber up and down, and makes to generate extruding and opposite fricting movement between steel ball,
Furthermore the steel ball above and below steel ball damper in working chamber is mutually flowed by circular passage, and friction is generated between circular passage,
The vibrational energy for absorbing and consuming equipment, plays effective cushioning effect.Since steel ball damper is all-metal structure, do not need
Daily maintenance is carried out, the use cost of damper is reduced, improves the service life of damper.A kind of steel proposed by the present invention
Pearl damper can also be applied to the antidetonation shock attenuation of bridge and building.
