Description
Technical field
This utility model relates to a kind of mechanical type unidirectional damping structure, belongs to mechanical driving device, is mainly used in machinery biography
The plugging of disorder of internal organs.
Background technology
In mechanical transmission mechanism, when needs plugging or counterweight, cut or polish jade with an emery wheel real frequently with hydro-cushion cylinder or counterweight
Existing, it is the biggest that compensating cylinder or counterweight stone roller size occupy greatly space.
Summary of the invention
For more preferably realizing mechanically operated unidirectional damping effect, this utility model provides a kind of mechanical type one-way damper knot
Structure, the drive mechanism of this Mechanical course is reliable and stable.
The technical solution of the utility model is: a kind of mechanical type one-way damper for machine driving plugging is tied
Structure, including gear shaft, fixed support, bearing, hole back-up ring, revolution voussoir, roller, shaft block ring, nut, butterfly spring, outer
Friction plate, inner attrition piece, revolving sleeve, driving key, lining, described gear shaft is bearing in fixed support by bearing, turns round wedge
Block is connected with gear shaft by key connecting, and revolution voussoir excircle is disposed with the unidirectional wedge-shaped slot of decile, described revolving sleeve one end
Endoporus with revolution voussoir cylindrical matched in clearance, revolving sleeve with revolution voussoir wedge-shaped slot in be equipped with roller, described rolling
Big end is less than the gap of groove in wedge-shaped slot for column diameter, and the other end endoporus of described revolving sleeve is bearing in gear shaft by lining
On, the cylindrical of described revolving sleeve is equipped with inner attrition piece by spline drived, with the outside friction disc of inner attrition piece cross assembly
Being stuck on fixed support, the outside of interior outside friction disc is equipped with butterfly spring, and described butterfly spring compresses under nut effect
Interior outside friction disc, described shaft block ring limits gear shaft and the axial displacement of axle group part.
During application, fixed support is connected on machine driving casing, and the gear on gear shaft is connected with mechanical drive train, when
When gear shaft one direction rotates, in the revolution voussoir on gear shaft drives wedge-shaped slot, roller rotates, and the big of wedge-shaped slot be close to by roller
End and with revolution voussoir synchronous axial system, now the interior outside friction disc on revolving sleeve and revolving sleeve does not turns under butterfly spring effect
Dynamic, when machine driving adverse movement, the wedge-shaped slot on revolution voussoir cylindrical and roller adverse movement, roller is in inertia force effect
Under snap in wedge-shaped slot small end formed frictional force, revolution voussoir by roller drive revolving sleeve synchronous axial system, pass through adjusting nut
Controlling the internal outside friction disc of butterfly spring and produce the size of frictional force, the moment of resistance that interior outside friction disc sliding friction produces is to gear
The adverse movement of axle produces damping action.
Accompanying drawing 1 is this utility model one mechanical type one-way damper structural representation, and accompanying drawing 2 is this utility model structure
At revolution voussoir, roller, the sectional drawing of revolving sleeve position.
Detailed description of the invention
Seeing accompanying drawing, this utility model provides a kind of mechanical type one-way damper, including gear shaft 1, fixed support 2, axle
Hold 3, hole back-up ring 4, revolution voussoir 5, roller 6, shaft block ring 7, nut 8, butterfly spring 9, outside friction disc 10, inner attrition piece
11, revolving sleeve 12, driving key 13, lining 14.
The gear shaft 1 of described a kind of mechanical type one-way damper can rotate under the supporting of bearing 3, logical on gear shaft 1
Cross key 13 connection and have revolution voussoir 5, gear shaft 1 is supported with revolving sleeve 12 by lining 14.
Being connected by spline on described revolving sleeve 12 has inner attrition piece 11, outside friction disc 10 to be stuck on fixed support 2, institute
State and on revolving sleeve 12, be also configured with butterfly spring 9, nut 8, compress butterfly spring 9 by adjusting nut 8 and control inner attrition piece 11
Normal pressure size with outside friction disc 10.
During described gear shaft 1 one-directional rotation, revolution voussoir 5 drives roller 6 to be close to the big end of wedge-shaped slot, revolving sleeve 12 and in rub
Pad 11, outside friction disc 10, butterfly spring 9 do not rotate, and during gear shaft 1 adverse movement, revolution voussoir 5 drives roller 6 to snap in
Wedge-shaped slot small end, drives revolving sleeve 12 to move by frictional force, and revolving sleeve 12 is at inner attrition piece 11, outside friction disc 10, butterfly bullet
The moment of resistance is formed under the pressure of spring.Mechanically operated adverse movement just can be slowed or stopped.
