Typical structure of reciprocating swing hydraulic motor

① Bidirectional single to compound swing motor (Fig. d) the reciprocating mother piston 2 of bidirectional single to compound swing motor only moves in a straight line. Structurally, the left and right shafts are symmetrical, and the left and right shafts are connected through the synchronizing rod 3 to realize synchronization. This kind of hydraulic motor is mainly used to drive two loads on the same axis to rotate synchronously.

② Slender single to compound swing motor (Figure E) this is a single to compound swing motor used for turning the slide of rock drill on the jumbo boom. The reciprocating rod on the piston 5 is matched with the reciprocating screw pair on the main shaft 1, the main shaft is connected with the slide way, and the shell 3 is fixed on the drill arm through the flange shaft 6. When the pressure oil enters the left chamber of the housing from port a, the piston moves to the right along the straight spline pair 8. Because the drill arm does not move, when the piston moves in a straight line, the main shaft is forced to rotate together with the slideway through the double screw pair 7. On the contrary, when the pressure oil enters from port B, the slide will reverse. The advantage of the motor is that it can drive the slender working mechanism to rotate.
