    • A process for installing a stator slide under a stator wedge in a radially oriented slot of a stator core assembly includes: a) loading windings in the radial slot, the radial slot having axially extending dovetail grooves in opposing sidewalls thereof; b) loading at least one stator wedge and stator slide in the dovetail grooves of the slot, and tightening the at least one stator wedge with the stator slide; c) loading at least one additional stator wedge in the dovetail grooves; d) locating at least one additional stator wedge slide relatively loosely under the additional stator wedge; and e) using the at least one stator wedge as a force reaction point, applying a force to the additional stator slide to drive the additional stator slide under the additional stator wedge. The tool for driving the stator slide under the stator wedge has a frame including a pair of elongated rail members; a force application cart located between the rail members, the force application cart having a force block thereon; a drive connected to the frame, substantially intermediate opposite ends of the frame; a lead screw threadably engaged at one end with the force application cart and connected at an opposite end to the drive such that the drive rotates the lead screw when actuated. Rotation of the lead screw causes axial movement of the force application cart and the force block against the slide in a tightening direction. A pin locates the tool relative to the stator slide, and establishes a reaction point for forces applied by the drive block to the stator slide.
    • 用于在定子芯组件的径向定向的槽中的定子楔下方安装定子滑块的过程包括:a)在径向槽中加载绕组,所述径向槽在其相对的侧壁中具有轴向延伸的燕尾槽​​; b)将至少一个定子楔和定子滑块装载在槽的燕尾槽中,并用定子滑块收紧至少一个定子楔; c)在燕尾槽中加载至少一个额外的定子楔; d)在附加的定子楔下面相对松动地定位至少一个附加的定子楔形滑块; 以及e)使用所述至少一个定子楔形件作为力反作用点,向所述附加定子滑块施加力以驱动所述附加定子楔块下的附加定子滑块。 用于在定子楔下方驱动定子滑块的工具具有包括一对细长轨道构件的框架; 位于轨道构件之间的施力推车,其上具有力块的施力推车; 连接到框架的驱动器,基本上在框架的相对端部的中间; 导螺杆在一端与施力推车一起螺纹连接,并在与驱动器相对的端部连接,使得驱动器在致动时旋转导螺杆。 导螺杆的旋转导致施力推车和力块沿紧固方向抵靠滑块的轴向移动。 销钉相对于定子滑块定位工具,并为驱动块施加到定子滑块的力建立起反应点。
