摘要：A shaft puller is provided for extracting a shaft having a threaded end exposed from a surround structure. The puller includes a housing having a threaded bore therethrough with the threads being of an opposite hand from the threads of the shaft. The puller also includes a spindle member having external threads which threadably engage the bore of the housing. The spindle member also has a bore therethrough to permit engagement of the spindle member and housing onto the shaft. With the spindle member engaged into the housing, the spindle is placed over the shaft and a nut, normally received on the shaft, engaged thereon against the end surface of the spindle member. By turning the spindle member in a direction to advance the nut on the shaft, the spindle member turns out of the housing to extract the shaft from its surround structure by acting between a reaction face on the surround structure and the nut on the shaft.
