Wind generating set gear box elastic support device convenient to disassemble and adjust

Abstract

The invention discloses a wind generating set gear box elastic support device convenient to disassemble and adjust. The device comprises a shock absorption support seat, an upper shock absorber and a lower shock absorber. The device is characterized in that the shock absorption support seat comprises an upper beam, two uprights and a lower seat plate, wherein the upper beam is detachably connected with the upper parts of the two uprights, and the lower seat plate is detachably connected with the lower parts of the two uprights; a mounting hole passes through the center of the upper beam; the device also comprises an upper shock absorber mounting component, a lower shock absorber mounting component and a locking / disassembling adjusting component, wherein the upper shock absorber mounting component is arranged at the inner lower part of the mounting hole of the upper beam; the lower shock absorber mounting component is arranged on the lower seat plate; the locking / disassembling adjusting component is arranged at the inner upper part of the mounting hole and contacts the top part of the upper shock absorber mounting component; and when the top part of the locking / disassembling adjusting component is level with the top surface of the upper beam, the bottom part of the upper shock absorber mounting component protrudes out of the bottom surface of the upper beam. The device has the advantages of large bearing capacity, good shock absorption performance, simple structure and safety and reliability, and is convenient for maintenance and replacement of elements.

Description

technical field [0001] The invention belongs to the field of vibration-reduction, noise-reduction and shock-resistance products, and in particular relates to an elastic support device for a gearbox of a wind power generating set that is easy to disassemble and adjust. Background technique [0002] With the gradual expansion of China's wind energy market, the installed capacity of large-scale wind turbines in various wind regions has grown rapidly, which has made a certain contribution to alleviating the power supply pressure of the national power grid and curbing the deterioration of the environment. However, when large-scale wind turbines are working, the vibration and noise exceed the standard due to the reduction of parts processing accuracy and assembly quality, which will not only affect the output of the unit and the service life of the parts, but also the noise generated by the unit will also affect the normal life of the surrounding residents. . In the process of lo...

Problems solved by technology

Not only that, because most of the domestic wind turbines are imported from foreign technology, the digestion and absorption of technical data is not perfect, and there is a lack of special talents for vibration and noise control, so the selection of vibration damping components for wind power equipment is generally imported directly.

[0003] At present, the main products for vibration reduction of foreign gearboxes include two-half shell elastic support, frame elastic support, multi-layer elastic support, damping elastic support and conical elastic support, etc., but these products generally require a very large preload force It can be installed only with the help of special equipment. It is very difficult to install and disassemble, especially in a small cabin. It is difficult to maintain and replace
