Embodiment 1

[0030] like figure 2 As shown, a rack and pinion type marine anti-vibration support device includes a spring 2, a lower support frame 3, an upper support frame 4, a guide rail assembly 5, a pin shaft 6, a rack 7, and a gear 8.

[0031] Several springs 2 are fixedly arranged between the lower supporting frame 3 and the upper supporting frame 4 . In this embodiment, the lower support frame 3 and the upper support frame 4 are two square steel plates with the same specifications, and the springs 2 are arranged on the four corners of the square lower support frame 3 and the upper support frame 4 .

[0032] The bottom surface of the upper support frame 4 is provided with a pair of left and right symmetrical lifting lugs, and one end of the tooth bar 7 is installed on the lifting lug of the upper support frame 4 by pin 6 rotation, and the tooth bar 7 can move up and down with the upper support frame 4.

[0033] like image 3 As shown, the lower support frame 3 is provided with a s...

Embodiment 2

[0044] like Figure 5 As shown, in this embodiment, the number of gears 8 is 4, and the dimensions and specifications of the 4 gears are all identical, and they are symmetrically distributed. One end of the two gears on both sides meshes with the tooth surface of the corresponding rack to form a rack and pinion pair, and the other side meshes with the adjacent gear. The two gears in the middle position mesh with adjacent gears on both sides.

[0045] Compared with the gear size in Embodiment 1, the diameter of the gear in this embodiment is smaller than that in Embodiment 1.

Embodiment 3

[0047] As shown in 6, in this embodiment, the number of gears 8 is four, and the sizes and specifications of the four gears are not exactly the same, and they are arranged symmetrically. The two gears on both sides have the same diameter, one end of which meshes with the tooth surface of the corresponding rack to form a rack and pinion pair, and the other side meshes with the adjacent gear. The two gears in the middle are the same diameter and mesh with adjacent gears on both sides.

[0048] What's more, the size of the two gears in the middle is smaller than the size of the two gears on the sides.

Abstract

The present invention provides a rack-and-pinion marine anti-vibration supporting device, which includes a spring, a lower support frame, an upper support frame, and guide rail assemblies arranged in pairs, racks and gears. The vibration generated by the operation of marine mechanical equipment is transmitted to the upper support frame, and the vibration is reduced by the spring and transmitted to the hull; the low-frequency sway of the hull in the waves causes the mechanical equipment to shake together, and the shaking motion is transmitted to the symmetrically arranged racks on both sides through the upper support frame, causing The reverse reciprocating motion of the racks on both sides, the racks on both sides respectively drive the gears to rotate in the same direction, and the gear pairs meshing together can only rotate in the opposite direction, thus increasing the overall torsional stiffness of the chassis and reducing the shaking of mechanical equipment sports. The present invention adopts modular design, manufacture and installation, has simple structure, low cost and good anti-vibration effect.

Description

technical field [0001] The invention relates to a supporting device for marine mechanical equipment, in particular to a rack-and-pinion type marine anti-rolling and vibration-reducing supporting device, which belongs to the technical field of ship vibration-damping equipment. Background technique [0002] Marine machinery equipment can be divided into power machinery equipment and non-power machinery equipment. For power machinery equipment, such as the main engine, it is necessary to actively isolate its vibration to reduce the impact of the vibration generated by its work on the surrounding environment. For non-power machinery equipment, such as marine The operating table needs to be passively isolated from vibration to reduce the influence of the surrounding environment on it, so as to ensure the reliability of its work. [0003] In addition, during the sailing process of the ship, due to the action of wind and waves, the hull will also sway, and the moment generated by t...
