Description

Technical Field

[0001] The invention belongs to the technical field of improving vibration reduction performance, and in particular relates to a shock absorber with a rotating flywheel. Background Art

[0002] The steps involved from ship design to construction are often extremely cumbersome and the technologies involved are quite complex. In the current context of increasingly higher requirements for ship comfort, vibration and noise reduction of ship vibration and noise source equipment has also become a link that needs attention.

[0003] Rubber isolators can transform and dissipate vibration energy, and have excellent medium and high frequency vibration isolation effects, but their low frequency vibration isolation effects are poor. When ships are sailing at sea, due to bad weather conditions, there are a lot of low-frequency vibrations. The existence of low-frequency vibrations will not only affect the hull structure and instruments, endangering the normal navigation of the ship, but also seriously affect the health of the crew and the comfort of the ship. Therefore, reducing the low-frequency vibration of the ship's power equipment is particularly important to ensure the safe operation of the ship. In recent years, with the increasing demand for people's living environment, the requirements for vibration control have become more and more stringent. Summary of the invention

[0004] The present invention aims to solve the problems mentioned in the background technology and provides a shock absorber with a rotating flywheel.

[0005] In order to achieve the purpose of the present invention, the present invention discloses a shock absorber with a rotating flywheel, including a rotating mechanism, a shell, a metal rubber, a base, and a through-stud; the shell is mounted on the base, and the metal rubber is arranged between the two; two sets of rotating mechanisms are eccentrically arranged in a vertical mirror image in the base, and are meshed and installed with gears on the through-stud that penetrates the shell and the center of the base.

[0006] Furthermore, the base is concave, with a cavity in the middle, and through holes for rotating shafts of two sets of rotating mechanisms are installed on the cavity wall.

[0007] Furthermore, a bowl-shaped metal sheet is arranged inside the metal rubber.

[0008] Furthermore, a gear is arranged in the middle of the stud, and a damping material is arranged on the bottom seat.

[0009] Furthermore, the rotating mechanism is composed of a gear-driven rotating mechanism and a flywheel, wherein the flywheel is provided with a large bearing, and the gear-driven rotating mechanism is provided with a small bearing.

[0010] Compared with the prior art, the significant progress of the present invention is that: 1) the present invention utilizes the cooperation of gears to convert the up and down reciprocating motion of the shock absorber into the rotational motion of the flywheel, thereby achieving the effect of energy consumption and effectively improving low-frequency vibration; 2) the mirror arrangement of the rotating mechanism can realize that during the reciprocating motion, the flywheels on both sides can only rotate in the same direction clockwise or counterclockwise, without causing sudden change of direction impact force to damage the mechanism.

[0011] In order to more clearly illustrate the functional characteristics and structural parameters of the present invention, further description is given below in conjunction with the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The reference numerals in the figure are: rotating mechanism 1, housing 2, metal rubber 4, base 5, through stud 6, gear-driven rotating mechanism 1-1, flywheel 1-2, small bearing 1-3, and large bearing 1-4. DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] The shock absorber with a rotating flywheel designed by the present invention utilizes the reciprocating motion of the vibration isolator during the vibration reduction process, designs a rack shape on the through bolt, and converts the energy of the vertical reciprocating motion into rotational kinetic energy by meshing with the gear of the rotating mechanism, thereby achieving a greater dissipation effect on low-frequency energy.

[0018] like Figure 1 , Figure 2 As shown, in order to achieve the above-mentioned purpose, the technical solution adopted by the present invention to achieve the purpose is:

[0019] A shock absorber with a rotating flywheel comprises a rotating mechanism 1, a housing 2, a metal rubber 4, a base 5, and a through stud 6; the housing 1 is mounted on the base 5, and the metal rubber 4 is arranged between the two; two groups of rotating mechanisms 1 are arranged in an eccentric vertical mirror image in the base 5, and are meshed and installed with the gears on the through stud 6 that penetrates the center of the housing 2 and the base 5. The base 5 is concave, with a cavity in the middle, and through holes for the rotating shafts of the two groups of rotating mechanisms 1 are installed on the cavity wall. A bowl-shaped metal sheet is installed inside the metal rubber 4. A gear is arranged in the middle of the through stud 6, and a damping material is arranged on the bottom seat. The rotating mechanism 1 is composed of a gear-driven rotating mechanism 1-1 and a flywheel 1-2, wherein a large bearing 1-4 is installed on the flywheel, and a small bearing 1-3 is installed on the gear-driven rotating mechanism 1-1.

[0020] The working principle of the impedance composite silencer structure of the present invention is as follows: when the vibration isolator is working, it makes up and down reciprocating motion. At this time, the gear penetrating the screw rod will push the gear of the rotating mechanism to push the rotating mechanism to make a rotation motion. At this time, the gear pushes the rotating mechanism to be acted upon by centrifugal force, and the push rod will push the flywheel to make a rotation motion. When moving downward, one side gear pushes the push rod of the rotating mechanism to make a counterclockwise motion, and at this time, the flywheel on this side is pushed to rotate, while the flywheel on the other side moves clockwise, and at this time the push rod cannot push the flywheel to move. When moving upward, the opposite is true, so that the flywheels on both sides can simultaneously make rotation motion in only one direction of their own.

[0021] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
