Description
Technical field
The present invention relates to a kind of mechanical transmission mechanism, and in particular to a kind of centrifugal friction damper of delicate structure.
Background technology
In traditional transmission mechanism, for damper frequently with vortex flow damping principle, the theory structure has its shortcoming as follows:Knot
Structure is complicated, generally requires multi-stage gear speedup to reach predetermined damping;Bulking value is big, and it is tight not to be suitable for overall space
Gather and occasion that weight demands are harsh;Difficulty of processing is big, and cost is high.
The content of the invention
The purpose of the present invention is:Overall space is compact, lightweight requirements are tight, and take into account processing and material cost should
With occasion, in order to overcome the weak point of existing damper, the present invention uses a kind of centrifugal friction damper of delicate structure.
The technical scheme is that:A kind of centrifugal spin friction damper, including it is rotary body 1, guide finger 2, wear-resisting
Ring 3, centrifugation body 4, shell body 5, wherein rotary body 1 is closest to the center of circle of shell body 5, if the circumference of rotary body 1 is to being evenly distributed with
One end of several guide fingers 2 of dry pin-and-hole, pin-and-hole and equivalent amount is fastenedly connected;Centrifuge and set on the inner arc surface of body 4
There is sliding eye, centrifugation body 4 is installed by the other end of sliding eye and guide finger 2 to be coordinated, and freely relative can be slided between the two;
By the connection of guide finger 2, rotary body 1 drives the centrifugation coaxial rotating of body 4;Wear ring 3 be installed on centrifugation body 4 and shell body 5 it
Between, and be connected with the inner wall tightening of shell body 5.
Wherein, it is consistent with the outer arc radius of rotary body 1 to centrifuge the inner arc radius of body 4, centrifuges the outer arc radius of body 4
It is consistent with the inner arc radius of wear ring 3.Under inactive state, centrifuge between body 4 and wear ring 3 and gap be present.Wear ring 3 uses
Nonmetallic wear-resistant material.
It is an advantage of the invention that:A kind of centrifugal spin friction damper of the present invention, using centrifugal principle, by rotary friction
By-product life damping force is wiped, principle is exquisite, volume weight is light and handy;Secondly, wear ring is set in rubbing surface, effectively increases damper
Working life and stability, again, this centrifugal spin friction damper structure is simple, manufacture easy to process, favorably
In producing in batches and promote the use of.
Brief description of the drawings
Fig. 1 is a kind of structural representation of centrifugal spin friction damper of the present invention.
Fig. 2 is the centrifugation body structural representation in the present invention.
Wherein, 1- rotary bodies, 2- guide fingers, 3- wear rings, 4- centrifugations body, 5- shell bodies.
Embodiment
The present invention is described in further details below.Referring to Fig. 1 and Fig. 2,
The present invention includes rotary body 1, guide finger 2, wear ring 3, centrifugation body 4, shell body 5, and wherein rotary body 1 is outside
The center of circle of housing 5, the circumference of rotary body 1 to being evenly distributed with several pin-and-holes, several guide fingers 2 of pin-and-hole and equivalent amount
One end is fastenedly connected;Centrifuge and be provided with sliding eye on the inner arc surface of body 4, centrifugation body 4 is another by sliding eye and guide finger 2
End installation coordinates, and freely relative can slide between the two;By the connection of guide finger 2, rotary body 1 drives centrifugation body 4 coaxial
Rotation;Wear ring 3 is installed between centrifugation body 4 and shell body 5, and is connected with the inner wall tightening of shell body 5.Rotated in rotary body 1
Under caused centrifugal action, the exterior arc surface of centrifugation body 4 is bonded with wear ring 3 and Relative friction occurs, and produces damping and makees
With.
Wear ring 3 uses nonmetallic wear-resistant material, can strengthen the working life of damper and ensure the steady of damping capacity
It is qualitative.
Using the frcition damper volume structure of centrifugal principle it is exquisite, it is in light weight, easy to process and assembling, disclosure satisfy that winged
Machine, guided missile are to small product size, weight and the high standards of mass production.
