Effective protection equipment and basis.The absorptivity of buffer can reach more than 85%.After external load disappears,
Can determine the adjustable elastic cell parameters according to designing requirement, buffer be automatically reset or multiple
The position.But the runback digit buffer is mainly used in the buffering occasion, and the buffer that does not reset is mainly used in system
Moving occasion.
3. the utility model reasonable in design is easy for installation, and is optional with flange, multiple installation such as hinged
Form.No deterioration phenomenon, long service life, the maintenance nursing is simple and easy.
Description of drawings
Accompanying drawing 1 for the utility model structure collectivity cross-sectional schematic (with the flange installation form, can automatically reset slow
Towards device is example)
Among the figure: the 1-outer sleeve, the 2-piston rod, 3-is end cap fixedly, and 4-is end bracket enclosed and guiding fixedly, 5-adjustable elastic unit, the 6-end cap external sealed that floats, 7-float end bracket enclosed and guiding, the 8-end cap that floats, the 9-piston ring, 10-elastic colloid, this type of installation form flange of 11-cylinder body can be in the buffer ends, also can be at the buffer middle part.(illustrating with double dot dash line among the figure) but the runback digit buffer is mainly used in the buffering occasion.
Embodiment
Illustrated by accompanying drawing 1, the utility model is mainly by outer sleeve (1), piston rod (2), piston ring (9), fixedly end cap (3), adjustable elastic unit (5), the end cap (8) that floats, elastic colloid (10), cylinder body (11) and sealing guiding device are formed.Piston rod (2) and piston ring (9) are linked together in the seal container that is formed by float end cap (8) and cylinder body (11), piston rod (2), the end cap external sealed (6) that floats, the end bracket enclosed of floating and guiding (7) of packing into, this seal container inside has been full of the resisting medium-elastic colloid (10) with viscoelastic double grading, and when assembling, can accurately control the precompression of elastic colloid (10), in order to overcome system friction and the initial impedance power that designing requirement is provided.When buffer is subjected to external impacts, outer sleeve (1) maintains static, cylinder body (11) relative system produces relative movement, make motion in piston rod (2), piston ring (9) elastic colloid (10) in above-mentioned seal container, produce viscous damping force, simultaneously because piston rod (2) enters in this seal container, pressure elasticity damping body (10), the smaller volume of elastic colloid (10), press in the seal container to increase, destroyed the position balance that floating end covers (8) and adjustable elastic unit (5) under the buffer original state.The end cap (8) that floats moves to fixing end cap (3) direction under the promotion of elastic colloid (10), compression adjustable elastic unit (5), the seal container volume is increased, the seal container internal drop is low, adjustable elastic unit (5) are compressed the generation resistance simultaneously, and the end cap (8) that floats is obtained new position balance with adjustable elastic unit (5).In this course, end cap (8) increasess slowly with interior pressure of seal container that cylinder body (11), piston rod (2), the end cap external sealed (6) that floats, the end bracket enclosed of floating and guiding (7) form by floating, that is to say that buffer increases with displacement in the course of the work, the buffer elastic impedance try hard to keep hold basicly stable, elastic colloid (10) also keeps basicly stable with the viscous resistance that piston ring (9) relative movement produces, and resistance-displacement diagram is constant substantially.The utility model is given full play to the tough characteristic of elastic colloid (10) in buffering course, relies on elastic colloid (10) and the friction that piston ring (9) relative movement produces that most of impact energy is converted into heat energy dissipation.When adjustable elastic unit (5) are compressed into qualifying bit postpone, float end cap (8) relatively cylinder body (11) no longer move, the seal container volume that floats end cap (8) and cylinder body (11), piston rod (2) and seal formation such as guiding device no longer increases.Buffer is in remainder stroke, piston rod (2) continues to enter in this seal container, pressure elasticity damping body (10), make to press in the seal container and increase, produce relative movement at elastic colloid (10) and piston ring (9), when making impact energy be converted into heat energy dissipation, because elastic colloid (10) is compressed, the elastic potential energy that makes the part impact energy be converted into elastic colloid (10) stores.After external force disappeared, the elastic potential energy that piston rod (2), piston ring (9) rely on elastic colloid (10) to store resetted.When the qualifying bit postpone of reverse stroke to adjustable elastic unit (5), adjustable elastic unit (5) rely on self elastic reset, and the cylinder cap (8) that promotes to float resets.Buffer still is a power consumption process in Recovery Process.Piston rod (5) and fixedly between end cap (3), piston rod (5) and the unsteady end cap (8) design sealing and guiding device are arranged, and design external sealed between the cylinder body (11), guarantee piston rod (5) steadily effectively operation the time elastic damping medium do not leak.
Accompanying drawing 2 is the utility model structure collectivity cross-sectional schematic (with the flange installation form, not having the requirement that resets is example)
Among the figure: the 1-outer sleeve, the 2-piston rod, 3-is end cap fixedly, and 4-is end bracket enclosed and guiding fixedly, 5-air chamber, the 6-end cap external sealed that floats, 7-float end bracket enclosed and guiding, the 8-end cap that floats, 9-piston ring, 10-elastic colloid, 11-cylinder body
This kind structure is the another kind of form of expression of the present utility model, and the buffer that does not reset is mainly used in the braking occasion.Installation form can be selected other forms, to adapt to installation requirement.
The groundwork principle of this kind structure is identical with the structure shown in the accompanying drawing 1, and difference has been in the structure of accompanying drawing 2 with the air displacement in the air chamber (5) the adjustable elastic unit (5) in accompanying drawing 1 structure.Air chamber (5) is by fixing end cap (3), piston rod (2), float end cap (8) and a fixing seal container forming of end bracket enclosed and guiding (4), the end cap external sealed (6) that floats, unsteady end bracket enclosed and guiding (7), and air is full of this vessel space.The utility model utilizes air and the unsteady end cap (8) in the air chamber (5) to form the interior regulator control system of pressing, the interior pressure of the seal container that adjusting is formed by float end cap (8) and cylinder body (11), piston rod (2), the end cap external sealed (6) that floats, the end bracket enclosed of floating and guiding (7), make buffer realize buffer under balanced external force effect, the characteristic that resistance-displacement diagram is constant substantially.Pressure is lower in backhaul because in the air chamber (5), and buffer can not reset fully, needs reset by external force.
The utility model selects the elastic material of pressurized air, different Young's modulus to serve as according to the buffer usage requirement in the design of adjustable elastic unit.On the performance that realizes buffer,, only, can make the buffer of same structure satisfy multiple demand by regulating this design element of adjustable elastic unit all according to above-mentioned principle of uniformity.
