Owing to be provided with interlaced circular groove and annular wall between damping wheel and the shell, form Spielpassung between annular wall and the circular groove, like this, in the process that damping wheel relatively rotates with shell, increased the friction area of damping wheel and damping oil, thereby under the prerequisite that does not increase damper volume or damping oil viscosity, can realize increasing the purpose of damping value.
The center of described damping wheel has and can form circumferentially fixing bearing hole with a running shaft, and this bearing hole can be the waist shaped hole that connects.
Be formed with several cavitys on the described diapire, be provided with an oil storage cotton in each cavity.When damping wheel rotated with respect to shell, the damping oil of enclosure expanded because of frictional heat, but oil storage this moment cotton absorption portion damping oil, to keep the constant of damper internal pressure and damping size; And when damping wheel was static with respect to shell, damping oil returned to normal temperature, and the cotton release portion damping oil of oil storage this moment is to keep the constant of damper internal pressure and damping size.
Described Sealing comprise lay respectively between described base and the lid, between the central part of described damping wheel and the described base and the seal ring between this central part and the described lid.
Described shell comprises base and the lid that is tightly connected mutually by screw, described base is provided with first pouring orifice that is communicated with described closed chamber, described lid is provided with second pouring orifice that is communicated with described closed chamber, and described first pouring orifice and second pouring orifice are sealed by first sealed piece and second sealed piece respectively.The peripheral side of described shell has the limit structure that can cooperate with a locking device, is used for cooperating with a locking device, makes shell upwards static in week.This limit structure can be along even several watts shape groove spaced apart of described peripheral side.
Described shell and damping wheel can be metalwork, and this shell can be roughly cylindrical.

Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.In institute's drawings attached, identical mark will be used to refer to identical component, feature or structure.Embodiment introduce in the process at concrete structure or component only understand of the present utility model with reference to the property illustration as those skilled in the art; those skilled in the art can also design do not exceed the utility model technical scope and essence various and be equal to or the similar techniques structure under the enlightenment of this technological scheme; if it is unfavorable limiting the protection domain that the utility model claim included with this exemplary illustration thus, is equal to or is similar to the protection domain that the technical solution of the utility model still belongs to the utility model claim.And for simple and clear needs, the claimant has omitted the description of known function and structure.
Referring to Fig. 1 to Fig. 4, damper 1 comprises the roughly cylindrical metal shell 4 that is made of lid 31 and base 37, on the circumference side of this shell 4 evenly the compartment of terrain be distributed with several watts shape restraining groove 47, be used for cooperating with a locking device, make the shell 4 can be upwards static in week.Lid 31 is fixedly connected on base 37 by several screws 30, is provided with a bigger O RunddichtringO 34 between base 37 and the lid 31.Have one first pouring orifice 2 on this base 37, each seals screw 32 by one and cooperates a less O RunddichtringO 33 to seal to have one second pouring orifice, 3, the first pouring orifices 2 and second pouring orifice 3 on this lid 31.Be provided with a roughly cylindrical metal damping wheel 35 rotationally in the shell 4 that constitutes by base 37 and lid 31, this damping wheel 35 comprises diapire 354, central part 351, first annular wall 355 and second annular wall 356, be formed with between first circular groove, 357, the second annular wall 356 and the central part 351 between first annular wall 355 and second annular wall 356 and be formed with second circular groove 358; The internal surface of base 37 have with first circular groove 357 form Spielpassung the 3rd annular wall 371 and with second circular groove 358 form Spielpassung the 4th annular wall 372.Between the central part 351 of this damping wheel 35 and base 37 and be respectively equipped with an O RunddichtringO 38 between this central part 351 and the lid 31.Form a closed chamber between shell 4 and the damping wheel 35, above-mentioned first pouring orifice 2 and second pouring orifice 3 are connected with this closed chamber.The central part 351 of damping wheel 35 has the perforation bearing hole 352 of a waist shape, and this bearing hole 352 can form circumferentially fixing with the running shaft of controlling object.Four columniform oil storage cottons 39 are placed in four circular-shaped, concave cavity 353 on the diapire 354 of damping wheel 35, when damping wheel 35 rotates with respect to shell 4, the damping oil of shell 4 inside expands because of frictional heat, but the cotton 39 absorption portion damping oils of oil storage this moment, to keep the constant of damper internal pressure and damping size, and when damping wheel 35 is static with respect to shell 4, damping oil returns to normal temperature, the cotton 39 release portion damping oils of oil storage this moment are to keep the constant of damper internal pressure and damping size.
The working principle of this damper 1 is: damping oil 36 is injected in the above-mentioned closed chamber via first pouring orifice 2 or second pouring orifice 3, and in the oiling process, another pouring orifice is used for exhaust, makes and forms vacuum in the closed chamber.After finishing oiling, utilize two to seal screw 32 with above-mentioned two pouring orifices sealing, guarantee that damping oil 36 can not spill.The restraining groove 47 that distributes on the circumference side that utilizes a locking device and shell 4 cooperates and limit shell 4 rotates, when simultaneously damping wheel 35 running shaft that passed its bearing hole 352 drives, damping wheel 35 has with respect to shell 4 and relatively rotates, be enclosed in the interior damping oil 36 of closed chamber this moment when passing the Clearance Flow of each circular groove and each annular wall, damping wheel 35 is produced a resistance, obstruction damping wheel 35 relatively rotates with respect to shell 4, thereby reduces the rotational speed of damping wheel 35.If produce relative rotation between them, enough big external force must be arranged.
