Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
All the electrical components in the present application are connected with the power supply adapted to the electrical components through a wire, and an appropriate controller and an appropriate encoder should be selected according to actual conditions to meet control requirements, and specific connection and control sequences should be obtained.
The embodiment is as follows: according to the attached figures 1-3 of the specification, the manual telescopic output shaft type speed reducer comprises a speed reducer input flange motor flange 1, a speed reducer box body 2, a speed reducer internal gear assembly 3 and a hollow output shaft 4, wherein an inner hole of the hollow output shaft 4 is matched with a telescopic output shaft 12, and the telescopic output shaft 12 moves in the hollow output shaft 4 through key positioning.
The outer circle of the telescopic output shaft 12 is matched with the inner hole of the hollow output shaft 4, and the key connection is used for transmitting the output torque of the speed reducer. The nut (screw) 9 is fixed on the shaft end of the telescopic output shaft 12, and the screw (screw rod) 10 and the nut (screw) 9 form a thread pair. The matching length of the screw pair is equal to the moving distance of the telescopic output shaft, the screw (lead screw) 10 rotates to generate axial force to push the nut (screw) 9 and the telescopic output shaft 12 to move along the axis direction of the hollow output shaft 4, and the inner hole of the hand-operated wheel 5 is matched with one end of the shaft of the screw (lead screw) 10. The limit baffle 11 is fixed on the other shaft end of the screw (screw rod) 10, after the hand-operated wheel 5 is rotated, the nut (screw) 9 drives the telescopic output shaft 12 to move in the hollow output shaft 4 together, when the end reaches the foremost end, the end face of the nut (screw) 9 is tightly attached to the end face of the limit baffle 11, so that the telescopic output shaft 12 cannot move forwards continuously, the movable telescopic output shaft 12 can be prevented from separating from the hollow output shaft 4, and the protection effect is achieved. The screw (lead screw) 10 position limits the axial movement of the nut (nut) 9 by the bearing seat 6 with bearing assembly 7 and the locating stop 8.
