Abstract
The utility model discloses a damping spring combined vibration damper which is composed of a cylindrical upper housing, a cylindrical lower base and at least one vibration damping component arranged between the upper housing and the lower base, wherein, the center of the upper housing is provided with a connecting hole for externally connecting equipment. The upper end of the lower base is extended upwards with a section of coincident part with a decreased diameter. The upper housing and one outer side of the lower base are respectively provided with an upper rubber soundproof friction pad and a lower rubber soundproof friction pad. The utility model has the advantages of broad load range, low natural frequency, big damping ratio, high vibration isolation efficiency, safe and convenient use and long service life. The utility model can satisfy the requirements of various vibration damping and vibration isolatingengineerings.
Description
The utility model relates to a kind of vibration damper, relates in particular to a kind of damping spring combined vibration-damping device with covering.
Reasonable in the prior oscillating damper have a damping spring vibration damper, and it has the advantage that the load scope is big, natural frequency is low and damping is big.But because the spring of this vibration damper directly is connected with last lower shell body with bolt, noise is big, in case go up the lower shell body dislocation, easily makes vibration pass to housing until the basis by bolt, influences surrounding environment.For solving above-mentioned shortcoming, the applicant once applied for the patent of a combined vibration-damping device in 98 years, implemented so far, obtained effect preferably.But damping spring exposes during owing to use, therefore also has the shortcoming of easy corrosion and damage.
The purpose of this utility model is exactly in order to overcome the shortcoming of above vibration damper, and a kind of safe and reliable, the damping spring combined vibration-damping device that reduces high-frequency noise, increase damping and can increase the service life greatly that provide.
The purpose of this utility model is achieved in that a kind of damping spring combined vibration-damping device, by upper junction plate, bottom plate and be located at upper junction plate and bottom plate between at least one damping assembly constitute, described each damping assembly is one group of damping spring, also comprise two damping rubber pads, these two damping rubber pads are socketed in the two ends of described one group of damping spring respectively.It is characterized in that: described upper junction plate and bottom plate are respectively a columnar upper casing and a columnar lower bottom base, and upper casing can cover and be combined on the lower bottom base; The center of described upper casing is provided with an attachment hole, in order to external equipment; The center of described lower bottom base is provided with an attachment hole, the upper end of lower bottom base extend upward one section with the corresponding to position that overlaps of damping spring compression zone, the diameter at this coincidence position is slightly less than the internal diameter of upper casing; The outside of a described cylindrical shape upper casing and a cylindrical shape lower bottom base respectively is provided with rubber sound insulation friction pad and the friction pad of rubber sound insulation once on one.
Because the utility model has adopted above structure, damping spring is arranged in cylindrical shape upper casing and the cylindrical shape lower bottom base, make that the vibration damper of making has the load wide ranges, natural frequency is low and damping ratio is big, damping efficiency is high, safe and convenient to use, advantage that the life-span prolongs, can satisfy all kinds of vibration damping engineerings and environment requirement.
Concrete structure of the present utility model is further provided by following embodiment and accompanying drawing thereof.
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is one of the utility model user mode structural representations;
Accompanying drawing 3 is schematic representation of a kind of fixed plate of being used with the utility model.
See also accompanying drawing:
Fig. 1 is the utility model structural representation.A kind of damping spring combined vibration-damping of the utility model device, by a cylindrical shape upper casing 1 and a cylindrical shape lower bottom base 2 and be located between described cylindrical shape upper casing 1 and the cylindrical shape lower bottom base 2 at least one damping assembly 3 that is provided with and constitute, present embodiment is provided with 4 groups of vibration dampings and sets up.Described each damping assembly is one group of damping spring.Also comprise upper and lower damping rubber pad, described upper and lower damping rubber pad is set in the upper/lower terminal of this group damping spring respectively.One group of damping spring in described each damping assembly can be made of a damping spring, also can be made of the damping spring of two mutual sockets.The center of described upper casing is provided with an attachment hole 12, in order to external equipment; The center of described lower bottom base 2 is provided with an attachment hole 21.The diameter of upper casing 1 diameter that can lower bottom base and similar also can be slightly larger than the diameter of lower bottom base, make rainwater can not drench into.Extend upward in the upper end of lower bottom base 2 one section with the corresponding to position 22 that overlaps of damping spring compression zone, the diameter at this coincidence position 22 is slightly less than the internal diameter of upper casing, its height is directly proportional with the compressive strain scope of set damping spring in this vibration damper, and consistent.When this vibration damper work, damping spring compressive strain, upper casing can cover on the coincidence position of lower bottom base.The outside of a described cylindrical shape upper casing and a cylindrical shape lower bottom base respectively is provided with rubber sound insulation friction pad 13 and the friction pad 23 of rubber sound insulation once on one.
Accompanying drawing 2 is the utility model embodiment user mode figure, during use, the utility model is installed on the fixed connecting plate 3, fixed connecting plate 3 can be according to different use occasion and is different, Fig. 3 is a kind of fixed connecting plate schematic representation, its center is provided with an attachment hole 31, is connected with lower bottom base of the present utility model; A fixed hole 32 is respectively established on the fixed connecting plate both sides, so that fixed plate is fixed on the basis.
Natural frequency is at 2Hz～4.9Hz under load rating for the utility model, and normal range (NR) internal damping ratio is 0.06～0.07, can be under-40 ℃-110 ℃ environment proper functioning, and can adapt to rugged environment such as Exposure to Sunlight rainforest, gas attack, high temperature humidity.Can form series product, safe and reliable, the life-span is long.
