Description
The utility model relates to a kind of full-metallic vibration damper with rigidity high dampings such as three-dimensionals.
It is reported that existing vibration damper is of a great variety, but more advanced vibration damper is the vibration damper that adopts the damping net post and be with round spring on the damping net post.Though this vibration damper has had bigger progress, shortcoming such as it has x, y, three direction rigidity of z are inconsistent, and rigidity is non-adjustable.
The purpose of this utility model is, provides a kind of reasonable in design, and natural frequency is low, x, y, three direction rigidity of z high conformity, and rigidity is adjustable, rigidity high damping full-metallic vibration dampers such as the three-dimensional of long service life.
Technical solution of the present utility model is, will be by base plate, the round spring that is located on the base plate is decided plate, following gauze pad and sheath, be located at damping net post and the round spring that overlaps the damping net post on the round spring positioning plate, the vibration damper that passes through the block formation that chimb cooperates with sheath outside the bottom that is enclosed within damping net post and circle spring top is improved.
Adjustable for the rigidity that makes this vibration damper, have screwed top wire hole and bolt hole at the top of block, be provided with regulator board at the top of damping net post and circle spring.
Realize rigidity such as three-dimensional in order to make this vibration damper, on base plate, be provided with the top cover that is positioned at sheath, be provided with gauze pad down at circle spring positioning plate and top inner room, in the gap that sheath, top cover and block constitute, be provided with two ends be provided with packing ring in be provided with the damping wire circle on gauze pad.
The utility model and background technique are relatively, because in vibration damper, be provided with the structure of adjustable rigidity and rise the upper and lower, left and right damping function in be provided with steel traveler on gauze pad, therefore, not only solve rigidity and can be in harmonious proportion the problem of rigidity such as three-dimensional, and had advantages such as reasonable in design, high damping, long service life.Its natural frequency is less than 9H2, and the three-way rigidity inconsistency is ± 15%, and transmissibility is less than 1.5.
Below in conjunction with accompanying drawing, describe a specific embodiment of the present utility model in detail.
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1, base plate 16 is square plates, has rivet hole at the center and the place, 4 angles of base plate 16, and the middle part is fixed with round spring positioning plate 13 by rivet 14 on base plate 16.Damping net post 4 that is rolled into by stainless (steel) wire and the round spring 5 that overlaps damping net post 4 are installed on circle spring positioning plate 13.Top at base plate 16 has the bottom to be square by tubular-shank rivet 17 rivetings, and top is truncated cone shape and has the sheath 6 of center hole.Be welded with the top that is positioned at sheath 6 on the top of base plate 16 and have the cylindrical shape top cover 12 of center hole.Gauze pad 15 under circle spring positioning plate 13 and 12 in top cover are equipped with by the stainless steel of extrusion modling.Top at damping net post 4 and circle spring 5 is equipped with circular regulator board 3, and is with the top and is evenly equipped with 3 top wire holes and 1 centre bolt hole, and the bottom has the drum female cap cap 1 of outer edges of boards.In top wire hole and bolt hole, be screwed with jackscrew 2 and bolt 18.In sheath 6, top cover 12 and 1 gap that constitutes of blocking a shot the lower end is housed and is placed with a packing ring 11, the upper end is placed with gauze pad 9 on the stainless steel of extrusion modling of two overlap joint packing rings 7.8.In last gauze pad 9, stainless steel wire ring 10 is housed.
During use, rigidity high damping full-metallic vibration damper such as three-dimensional is connected with equipment, and according to using needs to adjust rigidity by jackscrew 2.
