Embodiment Construction

[0036] In the three vacancies between the six stiffener plates 10 inside the generator end cover, a plurality of cavities separated by baffle plates (most of which are rectangular, and there are other shapes at the edges) are designed to connect the horizontal plate 14 and the vertical plate 15 spot welded between the side plate 11 and the rib plate 10 of the end cover. The spacing and height of each plate are equal, and the direction is also designed to be vertical. Such as figure 1 , 2 shown.

[0037] Select industrial nylon Oxford cloth 16 with excellent mechanical properties such as tensile, flexural, scratch-resistant, and tear-resistant, and then use high-strength tensile and wear-resistant thread (PE braided thread or Dynema thread) to sew it into a cylindrical cloth bag. The bag diameter and the spacing of the riser 15 remain the same.

[0038] Spherical steel ball 17 particles are packed in the cloth bag, and the filling amount accounts for about 85% of the heigh...

Abstract

The invention relates to a particle damping vibration attenuation end cover and a main generator adopting the same, and solves the technical problems that the main generator in a diesel generator setfor an internal combustion locomotive is easily subjected to vibration conduction by the diesel engine, and then the service life and the normal operation of the diesel engine are influenced. The particle damping vibration attenuation end cover is characterized in that a plurality of reinforcing rib plates which surround a central bearing hole of the end cover and are distributed along the radialdirection of the bearing hole are fixed on the inner side of the end cover, the reinforcing rib plates divide the inner side of the end cover into a plurality of spaces, and the spaces are separated from each other to serve as air inlets and vacancies; each vacancy is divided into a plurality of rectangular small cavities by vertically-staggered transverse plates and vertical plates, the spacing of the horizontal direction of the rectangular cavities are the same, and a particle damping bag is filled in each rectangular cavity, wherein the particle damping bag is a cylindrical cloth bag with the diameter being the same as the horizontal direction spacing of the rectangular cavities, and the interior of the particle damping bag is filled with spherical steel balls with the filling amount accounting for 80% of the height of the cloth bag; and a cover plate matched with the vacancy shape is movably arranged on one side, facing the interior of the end cover, of each vacancy.

Description

technical field [0001] The invention relates to the damping technology of a diesel generator set for a diesel locomotive, in particular to a particle damping damping end cover and a main generator using the end cover. Background technique [0002] In recent years, with the continuous development of the railway industry, diesel locomotives are developing towards high-power integration. As the core component of diesel locomotive, diesel generator set will increase its vibration with the increase of power and speed. In an integrated diesel generator set, the main generator is used as an electrical energy output device, and its ability to withstand vibration is much smaller than that of a diesel engine. Therefore, reducing the vibration of the main generator has become a difficult problem faced by diesel locomotives at present. [0003] At present, diesel generator sets for diesel locomotives are mostly integrated structures, the main generator is supported by a single bearing...
