The invention provides a linear driving mechanism. The linear driving mechanism comprises a machine shell, a front cover, a rear cover, a stator and a rotor. The machine shell comprises a first machine shell body and a second machine shell body. The linear driving mechanism further comprises a rolling lead screw, a first bearing and a second bearing. The rolling screw rod comprises a sleeve which is arranged in the first machine shell and penetrates through the front cover, a screw rod nut which is fixed in one end, close to the rear cover, of the sleeve, and a central screw rod which is arranged in the screw rod nut and extends in the axial direction of the screw rod nut; the peripheral side of the sleeve is in sliding connection with the inner side of the first machine shell, and the center lead screw is sleeved with the lead screw nut which is in rotating connection with the center lead screw. The joint of the end, close to the rear cover, of the center lead screw and the rotor is of an integrally-formed s
