On the outside of the screw nut seat 6, a screw tail end bearing seat 8 is installed on one side of the screw nut seat 6, and the other end of the screw 5 is rotatably connected to the outer wall of the screw tail end bearing seat 8; a rotary joint 10 is connected through the outer wall of one side of the screw tail end bearing seat 8, and an oil inlet pipe 9 is connected through the outer wall of one end of the rotary joint 10, and a third high-pressure oil pipe 11 is connected through the outer wall of one side of the rotary joint 10, and the other end of the third high-pressure oil pipe 11 is connected through the outer wall of the screw tail end bearing seat 8, through the rotary joint 10 The cooling oil is injected into the screw 5, and after circulating from the tail end of the screw 5 to the main end, it is injected into the bearing seat 8 at the tail end of the screw through the third high-pressure oil pipe 11 through the rotary joint 10, so as to cool down the temperature of the bearing seat 8 at the tail end of the screw; a second high-pressure oil pipe 4 is connected through the outer wall of one side of the bearing seat 8 at the tail end of the screw, and the other end of the second high-pressure oil pipe 4 is connected through the outer wall of the motor seat 1, and a first high-pressure oil pipe 3 is connected through the outer wall of one side of the motor seat 1. After circulating, it is injected into the bearing seat 8 at the tail end of the screw through the third high-pressure oil pipe 11 through the rotary joint 10, so as to cool down the temperature of the bearing seat 8 at the tail end of the screw; a second high-pressure oil pipe 4 is connected through the outer wall of the bearing seat 8 at the tail end of the screw, and the other end of the second high-pressure oil pipe 4 is connected through the outer wall of the motor seat 1, and the first high-pressure oil pipe 3 is connected through the outer wall of one side of the motor seat 1. The oil pressure pipe 4 is injected into the motor base 1, and when circulating in the motor base 1, it is recirculated from the first high-pressure oil pipe 3 to the inside of the oil cooler, and then the cooling oil is cooled by the oil cooler; the bottom ends of the motor base 1, the screw nut seat 6 and the screw tail end bearing seat 8 are provided with bolt connection holes, and the motor base 1, the screw nut seat 6 and the screw tail end bearing seat 8 are placed in the specified position, so that the motor base 1, the screw nut seat 6 and the screw tail end bearing seat 8 are conveniently fixed to the specified machine by screws.
