MECHANICAL PULLER Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: part 10 is dismounted by bringing grips 2 in contact with it and rotating power screw 3. In the course of power screw rotation its axial position relative to shaft 11 is maintained by bushing 7 and axial bearing 5. Part 10 moves along shaft 11, shifts bushing 7 relative to axial bearing 5, further on it moves upon axial bearing 5 thus providing for stable axial position of power screw 3 until part 10 is completely pulled off. EFFECT: more convenient operation and enlarged functional capabilities. 2 cl, 3 dwg
