Description

one

The invention relates to marine engineering.

Known shock-absorbing support of the ship's mechanism, mainly the gearbox turbo-gear unit, located between the body of the mechanism and the supporting foundation and containing rubber-metal ring shock absorbers with outer and inner rings.

A feature of the described invention is that the annular dampers are mounted on rigid rods parallel to the axis of the mechanism, with some rings, such as external, rigid ribs connected to the mechanism case, and others, such as internal, to the flange mounted on the supporting foundation.

This allows for compact footing and reduces installation work.

In order to simplify the installation work and take into account the magnitude of the deformation of the shock absorbers under the action of the weight of the mechanism, in the flange mounted on the supporting foundation, threaded holes are made for squeezing mounting bolts.

FIG. I depicts a turbo-gear unit mounted on the proposed damping supports; in fig. 2 is a view along arrow AI in FIG. one; in fig. 3 is a section along BB in FIG. one; in fig. 4 shows a section along the line Bb of FIG. one;

in fig. 5 shows the node I in FIG. one; in fig. 6 is a diagram of a gearbox lifting on squeezing bolts during its alignment and installation.

The gearbox / ship turbo-gear assembly is mounted on annular rubber-metal shock absorbers 2, the holder 3 of which is connected to the upper flange 4 of the support. Dampers 2, clips 3, upper 4 and lateral 5 flanges, ribs 6 constitute the internal frame of the damping support. Ring rubber-metal shock absorbers are located parallel to the axis of the gearbox. The shock absorbers are two coaxial metal rings, which are vulcanized or pressed in firmly with rubber. The shock absorbers are pressed into the sleeves 3j which are rigidly connected to the upper and side flanges 4 and 5 by means of the ribs 6. To prevent the axial displacement of the annular shock absorbers, the locking rings 7 are used.

The upper flange 4 serves to fasten the damping support to the gearbox in a horizontal plane, and the side flange 5-

for fastening it in a vertical plane. The sleeves 8, the ribs 9 and the bottom flange 10 form an outer frame. The bottom flange 10 serves to attach the damping support to the ship foundation. In the bottom flange

there are tapped holes for squeezing

mounting bolts // that serve to lift the gearbox when it is centered (see fig. 2). The outer frame is closed by means of the clamping bolt 12, tightened with nuts 13 and passed through the inner rings of the shock absorbers 2, the yoke 8 and the rings 14. The nuts 13 serve to protect the clamping bolt 12 from axial displacement. The saving bolt 12 is almost hollow to save weight. .

In order to allow adjustment of the gaps between the annular shock absorbers and the outer frame holders 8, fitting rings 14 are mounted on the bolt. The inner and outer frames of the shock absorbing support do not have a metal contact and are only connected by rubber rubber annular rubber-metallic shock absorbers. Leveling pads 15 and 16 are used to adjust the position and centering of the gearbox.

All parts of the shock-absorbing support, with the exception of annular rubber-metal shock absorbers, are steel, but they can also be from other metals, for example, light alloys. Ship turbo-gear units develop forces acting on shock absorbers, measured in tons. To perceive such forces, an appropriate number of shock absorbers is required. A large number of shock absorbers is located two (see Fig. 6) and more rows parallel to the axis of the gearbox.

The support shock absorbers (see FIG. 5), where several short ring shock absorbers are pressed into one holder 3, are made prefabricated.

Two shock-absorbing supports, symmetrical about the axis of the gearbox, with upper and side flanges are firmly attached to the gearbox mounted on the ship's foundation. Inaccuracies in the processing of the attachment planes of the gearbox and the supports are compensated for by leveling pads / 5 (see Fig. 2). The gearbox mounted on the shock-absorbing supports is centered on the mounting squeezing bolts 11. After

The alignments determine the thickness of the lower leveling pads 16 by the gaps between the flange 10 of the shock-absorbing support and the plane of the ship's foundation. Since the mounting squeezing bolts are not in the reducer's paw, but in the lower flange of the shock-absorbing support, when lifting the gearbox on the mounting squeezing bolts, the annular rubber-metal dampers are under static load from the weight of the gearbox. Therefore, the amount of deflection of the damping supports of the plummet of the gearbox is automatically taken into account when determining the thickness of the leveling pads. To install the lower leveling pads 16, the gearbox is raised on the mounting squeezing bolts to the required height. After installing the gaskets, the gearbox is lowered onto the leveling pads. Then, the damping supports by the bottom flanges 10 are finally secured to the ship foundation.
