Problems solved by technology
[0004] In the real flight state, the mechanical environment of the steering gear is relatively complicated. The steering gear is always in a vibration environment during flight, and the locking torque of the friction disc will decrease significantly in the vibration environment, which cannot reliably meet the overall required locking torque. There is a certain coordination relationship between the shaft and the motor shaft, that is, it can only fall when it is turned to the specified position, otherwise it cannot be locked, so the reliability is lower than that of the friction disc locking mechanism

Embodiment 1
[0028] First install the electromagnetic pin lock 2 on the transition block 7 through the installation screw A9, and then fasten the shift fork 3, the electromagnetic pin shaft pressure plate 8 and the output shaft of the electromagnetic pin lock 2 through the installation screw B10, so that the output shaft of the electromagnetic pin is in line with the dial The fork 3 is linked, the electromagnetic pin lock 2 is energized when the electromagnetic pin lock is in the state of attraction, the output shaft of the electromagnetic pin lock drives the shift fork 3 to move up 3mm in the limit groove 3 of the transition block number 7, and the electromagnetic pin breaks in the loose state. Electricity, under the action of the spring force inside the electromagnetic pin, the output shaft of the electromagnetic pin lock drives the shift fork 3 to move down 3mm in the limit groove 12 of the transition block 7, thereby realizing unlocking and locking; in the locked state, the shift fork 3 ...

Belonging to the technical field of locking mechanisms, the invention specifically relates to a steering engine zero-position locking mechanism. The invention aims to provide the steering engine zero-position locking mechanism that controls the magnitude of an electromagnetic pin lock spring's restoring force to ensure reliable locking of a tightening mechanism under a fault state. The steering engine zero-position locking mechanism comprises a motor (1), an electromagnetic pin lock (2), a shift fork (3), a transition gear (4), a first-level gear (5), a motor gear (6), a transition block (7), an electromagnetic pin pressure plate (8), a connection screw A (9), a connection screw B (10), a limiting stopper (11) and a limiting groove (12). The motor (1) is disposed on one side of the electromagnetic pin lock (2), the electromagnetic pin lock (2) in mounted to the transition block (7) through the connection screw A (9), and the screw B (10) fastens the shift fork (3), the electromagnetic pin pressure plate (8) and the output shaft of the electromagnetic pin lock (2).
Description
technical field [0001] The invention belongs to the technical field of locking mechanisms, and in particular relates to a steering gear zero-position locking mechanism. Background technique [0002] The present invention is suitable for realizing the zero position maintenance of the rudder blade before the full bomb system is powered on, providing a certain locking torque, and rigidly connecting the steering gear output shaft rudder blade and the steering gear output shaft to lock in one position through the zero position locking mechanism. near the specified location. [0003] The commonly used locking mechanism is realized by a friction disc or pin shaft linked to the motor shaft, that is, a friction device or a locking device is added to the motor shaft. Before the full spring system is powered on, the motor shaft is locked by the friction disc or pin shaft. At a certain position, when the full spring system is powered on, the friction disc or pin shaft is separated from...
