Beschreibung
Zusammenfassung:	The invention relates to a conical threaded rod-bushing pair belonging to the field of applications of single-threaded rod hydraulic pumps. A conical threaded rod comprises a conical threaded rod external curved surface, a conical threaded rod small end face and a conical threaded rod large end face; a conical bushing comprises a conical bushing internal curved surface, a conical bushing small end face, a conical bushing large end face and a conical bushing external cylindrical surface; the conical threaded rod large end face and the conical bushing large end face form an inlet end of the conical threaded rod-bushing pair; and the conical threaded-rod small end face and the conical bushing small end face form an outlet end of the conical threaded rod-bushing pair. According to the conical threaded rod-bushing pair, processing and manufacturing of the conical threaded rod and the bushing are facilitated, the conical threaded rod makes a parallel-axis planetary motion in the bushing without axial displacement,
