Zusammenfassung:	The utility model discloses a plunger motor main shaft which comprises a main shaft body. A transmission part is arranged at one end of the main shaft body, a key groove is formed in the transmission part, a flat key is arranged in the key groove, a connecting disc is arranged at the other end of the main shaft body, a central ball socket matched with a central plunger is formed in the center of the connecting disc, the bottom of the central ball socket is communicated with an oiling channel arranged perpendicularly, ball sockets matched with plungers are formed in the periphery of the central ball socket, an oil containing cavity is formed in the bottom of each ball socket, and fixing holes for fixing a pressing plate are further formed in the connecting disc. The plunger motor main shaft has the advantages that the plunger motor main shaft is simple in structure, convenient to mount and reliable and flexible in transmission; the oil containing cavities are arranged in the bottoms of the ball sockets, smoothness of motion of ball heads of the plunges in the ball sockets can be guaranteed, and the operation speed of a plunger motor can be increased.
