Embodiment Construction

[0010] exist figure 1 Middle is the front view of the steering gear of the present invention. A closed cavity formed by the upper shell (1), the middle shell (2) and the lower shell (3) forms a complete shell. The control circuit (5) separated from the control circuit board (4) in this shell is respectively connected to the angle sensor (6) and the motor (12), and the rotation of the main shaft of the motor (12) drives the motor drive gear (7) on it. , the motor driving gear (7) drives the worm connecting gear (11) meshing with it, the worm connecting gear (11) is coaxial with the worm gear (9), and the worm gear (9) and the output gear (8) The shaft of the output gear (8) is connected with the angle sensor (6), and when the output gear (8) rotates to a certain angle, the angle sensor (6) senses the position information and feeds back to the control circuit Control the stall of motor (12) in plate (4), control the travel position that is connected to output shaft gear (8) an...

Abstract

The invention relates to a large-torque self-locking steering engine. The large-torque self-locking steering engine comprises an essential worm gear and output shaft gear speed reduction set in main transmission and is characterized in that an angle sensor and a motor are connected with control lines divided from a control circuit board in a closed shell, a main shaft of the motor rotates to drivea motor drive gear, the motor drive gear drives a worm connecting gear engaged with the motor drive gear, the worm connecting gear and a worm gear are coaxial, the worm gear and an output shaft gearare engaged with each other and driven to rotate together, a shaft of the output shaft gear is connected with the angle sensor at the bottom, after the output shaft gear rotates at a certain angle, the angle sensor inducts position information and feeds the position information back to the control circuit board, so that the motor is controlled to stop rotating, so that the stroke position of a steering disc connected to the upper face of the output shaft gear is controlled, at the moment, if the external force is larger than the torsion of the motor, rotation or an out-of-control condition canbe generated, and a self-locking function is achieved by the output shaft gear and the worm connecting gear engaged with the output shaft gear.

Description

technical field [0001] The invention relates to a steering gear combined with a circular gear and a worm gear, especially when the worm gear drives the circular gear to increase the torque, and the load at the torque end is too large, the circular gear prevents rotation through the worm gear self-locking and has a lower weight Light steering gear. Background technique [0002] At present, there are two main types of known steering gear: one is electro-hydraulic steering gear, that is, the motor drives the hydraulic equipment to control the stroke of the rudder. This kind of steering gear has a large torque, stable control and can prevent rotation. Most can only be used on board or ground equipment. The other is a light-duty steering gear consisting of a coreless motor, an ordinary circular gear reduction group, a circuit board, an angle sensor, and a casing. Although this kind of steering gear is very light in weight, its disadvantage is that the torque is small, and it can...
