Abstract
The utility model discloses a one-way damper, belonging to the field of construction machinery parts, wherein the one-way damper comprises a housing and a rotor; the rotor is coaxially arranged in the housing; damping fluid is filled in a cavity between the rotor and the housing; at least one groove along the axial direction of the rotor is arranged on the outer wall of the rotor; a damping block is arranged in the groove and stretches along the radial direction of the rotor; the outer end of the damping block is an inclined surface; and an elastic body is arranged between the inner end of the damping block and the inner end of the groove. The damping block is not separated as being limited by the groove and the housing at the same time; meanwhile, it is so convenient to assemble the damper that only the elastic body and the damping block are orderly mounted to the groove of the rotor, the damping fluid is coated outside the rotor, and the rotor is integrally arranged in the housing; besides, the damper in such a structure is ensured to maintain good damping effect after being used repeatedly as the damping block has a stable mounting structure state.
Description
Technical field
The utility model belongs to the engineering machinery part field, is specifically related to a kind of one-way damper.
Background technique
Mostly there is the short problem of Acceptable life in the one-way damper of existing technology, is promptly repeatedly using its damping of back to weaken gradually, even the forfeiture damping.Name is called " a kind of through the hydraulic damper that unidirectional damping block realizes that incorgruous rotating speed is different is set ", and the patent No. is the Chinese patent of " 201020192911.6 ", the axle core that it comprises shell and has a wing; The described axle wing be provided with damping hole and along the axle core diameter to chute, also be provided with the controlling device that constitutes by damping block and spring in the chute of the axle wing, described damping block outer end is the inclined-plane; And it is positioned at said damping hole, like this, when axle core sense of rotation and damping block inclined-plane when consistent; In the damping block indentation chute; Weakened the stopping of damp liquid, deattenuation, when axle core sense of rotation and damping block inclined-plane towards on the contrary; Then damping block causes damp liquid and stops, damping increases.Its beneficial effect is to have obtained good unidirectional damping effect, but its shortcoming is the assembling inconvenience of a wing and connected spring, damping block, i.e. unreasonable structure, production and processing difficulty.
Summary of the invention
The purpose of the utility model is: it is simple relatively to propose a kind of structure, but can obtain the one-way damper of good unidirectional damping effect, thereby overcomes the deficiency that existing technology exists.
For realizing the purpose of the utility model, adopt following technological scheme to be achieved: a kind of one-way damper includes shell and rotor; Rotor coaxial is located in the shell; And be filled with damp liquid in the cavity between rotor and the shell, offer at least one groove on the outer wall of described rotor, be provided with in the groove along the flexible damping block of rotor radial along rotor axial; The damping block outer end is the inclined-plane, is provided with elastomer between damping block the inner and groove the inner.
As preferred version: the angle between the flexible direction of the exterior edge face of described damping block and damping block is 30～60 degree.
As preferred version: described rotor upper end is provided with end cap, the bayonet socket clamping of end cap and shell aperture inward flange; The rotor lower end is provided with tupelo, and tupelo is connected with the rotary axis groove of shell inner bottom part.
Compared with prior art; The beneficial effect of the utility model is: owing on the rotor outer wall, offer at least one groove along rotor axial, be provided with in the groove along the flexible damping block of rotor radial, the damping block outer end is the inclined-plane; Be provided with elastomer between damping block the inner and groove the inner; Like this, because damping block receives the restriction of groove and shell simultaneously, can not break away from rotor; Simultaneously, the assembling of damper is very convenient, only needs elastomer and damping block are packed in the groove of rotor successively, outside rotor, coats damp liquid, rotor integral body is inserted in the shell can be accomplished assembling again; In addition, the damper of this kind structure can guarantee still to keep good damping after damper repeatedly uses because the mounting structure of damping block is in stable condition.

Embodiment
According to accompanying drawing the embodiment of the utility model is done a detailed explanation below.
Embodiment
According to illustrated in figures 1 and 2, the described a kind of one-way damper of present embodiment includes shell 1 and rotor 2; Rotor 2 is with being located in the shell 1; And be filled with damp liquid in the cavity between rotor 2 and the shell 1, offer 3 on the outer wall of described rotor 2, be provided with in the groove 23 along the damping block 5 of rotor 2 radial expansions along the axial groove 23 of rotor 2; Damping block 5 outer ends are the inclined-plane, are provided with elastomer 4 between damping block 5 the inners and groove 23 the inners.Angle between the exterior edge face of described damping block 5 and the damping block 5 flexible directions is 45 degree.Described rotor 2 upper ends are provided with end cap 21, bayonet socket 11 clampings of end cap 21 and shell 1 opening inward flange; Rotor 2 lower ends are provided with tupelo 12, and tupelo 12 is connected with the rotary axis groove 22 of shell 1 inner bottom part.
The assembling process of this one-way damper is such, at first seal ring 3 is set to the relevant position on the rotor 2, the elastomer 4 of then in the groove 23 of each rotor 2, packing into; And then the damping block 5 of packing into; Outside rotor 2, coat silicone oil then, at last shell 1 is set on the rotor 2, the end cap 21 of rotor 2 is engaged with the bayonet socket 11 of shell 1; Meanwhile, the tupelo 22 of rotor 2 also just snaps in the rotary axis groove 12.
As shown in Figure 2; When rotor 2 opposite shell 1 rotate counterclockwise; Silicone oil produces along rotor 2 partial pressure radially the inclined-plane, outer end of damping block 5, and damping block 5 shrinks in groove 23, thereby the resistance of 5 pairs of silicone oil of damping block reduces; Rotor 2 overcomes the resistance acting when housing 1 rotates few, and this moment, one-way damper was that low-resistance is rotated.
When rotor 2 clockwise rotates with respect to housing 1; Silicone oil produces pressure to the outer end (side opposite with the inclined-plane) of damping block 5; Damping block 5 can not move owing to the spacing of groove 23, thereby damping block 5 promotes silicone oil along move in the shell 1, owing to have viscous resistance between silicone oil and shell 1 inwall; Rotor 2 overcomes the resistance acting when housing 1 rotates many, and this moment, one-way damper was that high resistant rotates.
