Abstract

The invention relates to an actuator of a large-load anti-jamming electric steering gear, which belongs to the technical field of electric steering gears and solves the problem that the actuator of the existing electric steering gear is easily worn and stuck under the action of a large load. The executive mechanism of the large-load anti-seize electric steering gear includes: electric motor, ball screw pair, bushing, output shaft and main frame; the motor drives the ball screw of the ball screw pair to rotate, so that the ball screw nut Translational movement along the lead screw; the lead screw nut sleeve is provided with a transmission pin, and the transmission pin is provided with a bush; the bush can slide in the shift fork. The invention bears the load on the plane of the bushing, increases the area of ​​the load, and can effectively prevent the phenomenon of wear and sticking of the actuator; the invention only adds a bushing, does not require high installation space, and conforms to the development of integrated design trend.

Description

technical field [0001] The invention relates to the technical field of electric steering gear, in particular to an actuator for a large-load anti-jamming electric steering gear. Background technique [0002] As the servo system of missiles, underwater vehicles, drones and other aircraft, the steering gear controls the trajectory of the aircraft and is a high-precision position servo system. [0003] For the steering gear installed in the stern compartment of the aircraft, the installation space is a tapered area, and a central hole needs to be reserved for the power unit of the aircraft. Combined with the power requirements, the installation space is very compact. [0004] Common steering gears generally include hydraulic steering gear, pneumatic steering gear and electric steering gear. Hydraulic steering gear is suitable for aircraft with relatively large power levels, which are large in size, heavy in weight and prone to oil leakage; pneumatic steering gear requires high ...
