Embodiment Construction
[0010] The present invention will be described in detail below in conjunction with accompanying drawing of description, see figure 1 , which is a structural schematic diagram of a large-stroke highly integrated electric steering gear of the present invention. The large-stroke highly integrated electric steering gear includes a servo motor 1, a rope-drawn sensor 2, a lead screw gear reducer 3, a special-shaped nut 4, a servo controller 5, a screw 6, a screw 7, a screw Three 8, screw four 9, screw five 10, screw six 11, screw seven 12, screw eight 13, screw nine 14.
[0011] Servo motor 1 is an AC servo motor with three M2.5mm threaded holes on its end face, and is fixedly connected to the lead screw gear reducer 3 by screws 3 8, 4 9 and 5 10 with the same specification of M2.5mm ;The rope-drawing sensor 2 is a disc-shaped structure with two through holes on its end face, the size of which is Φ2.8mm. The drawstring sensor 2 realizes the threaded connection with the special-sha...

The invention discloses a large stroke high integration electric steering engine. The large stroke high integration electric steering engine comprises a servo motor, a leading screw gear reducer, a special nut, a stay rope type sensor, a servo controller, a first screw, a second screw, a third screw, a fourth screw, a fifth screw, a sixth screw, a seventh screw, an eighth screw and a ninth screw. The large stroke high integration electric steering engine can realize large stroke motion in a limit space on the condition that motion precision to a certain degree is satisfied. The large stroke high integration electric steering engine employs a precise trapezoid leading screw mechanism, on the condition that position precision of the mechanism is improved, the self locking function of the mechanism is realized, and system reliability is improved; through effective combination of the mechanism, high integration of motion and control systems is realized, control and motion realize integration, the volume is reduced, and weight is further reduced; a gear transmission mechanism with relatively high transmission efficiency is employed, and high torque output of the system is further realized.
Description
technical field [0001] The invention belongs to the field of electric steering gear, and relates to a large-stroke and highly integrated electric steering gear structure. Background technique [0002] In recent years, electric steering gear has been widely used in the fields of robots, air defense missiles, cruise missiles, launch vehicles, radar communications, etc., and the scope of application has gradually expanded to small aircraft such as portable air defense missiles, small unmanned aerial vehicles, and anti-tank missiles. [0003] With the vigorous development of aerospace technology and the development of various advanced precision-guided weapons, people have higher and higher requirements for the overall performance of electric steering gear, prompting the electric steering gear to continuously reduce its volume and mass, continuously increase its carrying capacity, and control performance. The development in the direction of continuous improvement can be summarize...
