Automatic switching type composite bearing for flood discharge gate of hydropower station
The invention discloses an automatic switching type composite bearing for a flood discharge gate of a hydropower station, which comprises a basic assembly, and the basic assembly comprises a fixed wheel bracket and a support frame which are respectively and fixedly arranged on a working surface, and a main shaft arranged on the fixed wheel bracket; the working assembly is provided with a basic wheel connected to the main shaft and a rotating wheel arranged on the basic wheel; and the sealing assembly is mounted between the main shaft and the working assembly and is used for waterproof sealing. According to the automatic switching type composite bearing for the flood discharge gate of the hydropower station, a traditional single rotating bearing is changed into the composite bearing, when the main bearing is clamped and cannot work normally, urgent treatment is not needed, the standby bearing can be automatically started to work, the working reliability of the flood discharge gate of the hydropower station is greatly improved, and the service life is prolonged. And a pure mechanical shear pin is used as an automatic switching device, so that the device can adapt to a complex working environment, rusting and aging do not need to be considered, the manufacturing process is simple, and the strength calculation principle is simple.
本发明公开了一种用于水电站泄洪闸门的自动切换式复合轴承，包括基础组件，其包括分别固定设置在工作面上的定轮支架和支撑架，以及设置在所述定轮支架上的主轴；工作组件，具有连接在所述主轴上的基础轮和设置在所述基础轮上的转轮；以及，密封组件，安装于所述主轴和工作组件之间用于防水密封。该用于水电站泄洪闸门的自动切换式复合轴承，由传统的单一转动轴承变为复合式轴承，当主用轴承发卡不能正常工作后，不用急需处理，可自动启动备用轴承工作，大大提升了电站泄洪闸门工作可靠性，并用纯机械式剪断销作为自动切换装置，可适应复杂的工作环境，无需考虑生锈和老化，且制作工艺简单，强度计算原理简单。
