Sleeve mounting and removal tool.

摘要

A tool for use in combination with an annular roll (10) fixed on the end of a shaft (12) by means of a sleeve (14) axially inserted in wedged engagement therebetween. The tool includes a hydraulically actuated piston-cylinder assembly having an axially extending mounting stem (28) which is adapted to be received in detachably interlocked engagement within an axial blind bore (38) in the end of the shaft (12). The cylinder (18) is rotatable on the stem (28) to adjust the tool between sleeve removal and sleeve inserting positions. When in the sleeve removal position, the piston (26) bears against the shaft end (10) and the cylinder (18) engages and removes the sleeve (14). When in the sleeve insertion position, the cylinder (18) is checked against a stop (32) on the mounting stem (28) and the piston (26) urges the sleeve (14) into wedged engagement between the roll (10) and the shaft (12).
