x射线源、高电压发生器、电子束枪、旋转靶组件、旋转靶以及旋转真空密封件
摘要：
本发明涉及x射线源、高电压发生器、电子束枪、旋转靶组件、旋转靶以及旋转真空密封件。具体地，一种用于x射线源的旋转靶组件，所述组件包括：x射线发射靶；真空壳体；轴，安装所述靶并且穿过所述体的壁；轴承，可旋转地支撑所述轴；以及轴承壳体，支撑所述轴承，并且被安装在真空壳体的所述壁上，其中，通过扭矩限制器将轴承壳体安装在真空壳体的所述壁上，以使得当轴承壳体与真空壳体之间的扭矩超过预定的扭矩时，轴承壳体相对于真空壳体旋转，其中：所述扭矩限制器被布置为在真空壳体与轴承壳体之间施加摩擦力并且被布置为容许真空壳体和轴承壳体在所述预定的扭矩下相对于彼此进行滑动；轴承壳体和真空壳体中的一个具有法兰，而轴承壳体和真空壳体中的另一个具有夹钳组件；所述夹钳组件被布置为将所述摩擦力施加于所述法兰；并且所述夹钳组件包括被布置为接触法兰的一侧的能量吸收板、以及被布置为抵靠着能量吸收板推动法兰的夹钳。
摘要（英）：

The assembly includes an X ray emission target; a vacuum housing; a shaft mounted on the target and penetrating through the wall of the targe body; a bearing supporting the shaft in a rotary manner; and a bearing housing supporting the bearing and mounted on the wall of the vacuum housing. The bearing housing is mounted on the wall of the vacuum housing through a torque limiter so as to enable the bearing housing to rotate relative to the vacuum housing when a torque between a bearing housing and a vacuum housing exceeds a predetermined torque. The torque limiter is arranged to apply friction between the vacuum housing and the bearing housing and is arranged to allow the vacuum housing and the bearing housing to slide relative to each other in a predetermined torque. One of the bearing housing and the vacuum housing is provided with a flange and the other is provided with a clamp assembly. The clamp assembly is arranged to apply the friction to the flange and is configured to contacting with an energy absorption board on one side of the flange and to lean against the energy absorption board to push clamps of the flange.
