Description

Supporting device for motor impact-resistant vibration test

Technical Field

The invention relates to the field of generator assembly, in particular to a supporting device for a motor impact-resistant vibration test.

Background

Generators using internal combustion engines as a source of power often employ a single support structure (as shown in fig. 12). The generator with the structure is provided with a bearing only at the non-transmission end. The end face of the upper driving end of the stator base of the generator is rigidly connected with the engine body of the internal combustion engine through a connecting box; the rotor of the generator is connected with the crankshaft of the internal combustion engine through an elastic coupling, and at the moment, two supporting points of the rotor are respectively a bearing of the generator at a non-transmission end and a crankshaft bearing at an output end of the internal combustion engine. The generator and the internal combustion engine form a unit, and the unit is usually fixed in 2 modes: 1. is fixed to the ground or other mounting plane only by a plurality of elastic supports on the internal combustion engine; 2. is fixed to the ground or other mounting surface by a plurality of resilient supports on the internal combustion engine and generator. The end face of the stator base at the transmission end of the generator adopting the fixing mode 1 is the only installation fixing position in the working state.

The generator is subjected to impact vibration resistance test, and the purpose is to test the stability, reliability and safety of the whole generator and each part under impact and vibration environments. In testing, the generator is mounted on a test stand that is capable of controlled vibration and shock, and the test stand provides a shock vibration environment similar to or more severe than the actual operating environment. Before and after the test, the generator is required to run rotationally (which may be in motor mode, or towed) to demonstrate its functional integrity. During the test, the generator may also be required to remain in rotational operation.

The single generator with single supporting structure and end face installation cannot complete the shock-resistant vibration test because the end face of the driving end of the stator base cannot be directly connected with the shock vibration test stand, and because the end face of the driving end of the stator base is provided with a bearing at the non-driving end and cannot independently operate, because of the self structural characteristics of the single generator (the single generator can only be dragged or operated in a motor mode after being connected with an internal combustion engine or a similar mechanism in the prior art, such as a TQFR-3000 type main generator).

By way of example, outside the intermediate tube 506, there are a plurality of external ribs 513 of various shapes and sizes between the vertical plate 502 and the inclined plate 503; inside the middle tube 506, a plurality of inner ribs 514 with different shapes and sizes are arranged between the vertical plate 502 and the inclined plate 503. A bottom rib 517 is arranged at the edge of the long side of the bottom plate 501 between the vertical plate 502 and the inclined plate 503, and a lifting hole is arranged on the outer rib 513 right above the bottom rib 517 and can be used for independently lifting the rack support assembly 6.

Based on the above-mentioned structure, can guarantee holistic stability through setting up interior muscle 514 and outer muscle 513, extend little riser 510 and arc board 512 to bottom plate 501 in middle section of thick bamboo 506 bottom simultaneously, it is mainly in order to reserve the assembly space, and the convenience is fixed to the bolt of the bottom on end cover 1 and riser 502, reduces the assembly degree of difficulty.

Illustratively, a cross support is provided in the middle of the left support 504 and the right support 505 on the large opening 508. The cross support consists of an "X" shaped bottom plate 515 and 4 risers 516. The vertical plate 516 is triangular near the left and right supports 505; an end rib plate is arranged near the edge of the short side of the bottom plate 501 near the large opening 508 of the bottom plate 501, and is connected with the left and right supports 505, and the part near the left and right supports 505 is triangular. The purpose of the cross supports and the end rib plates is to improve the transverse rigidity of the left support 504 and the right support 505 and restrain the tendency of the cross supports and the end rib plates to tilt in the transverse direction.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
