Embodiment Construction

[0013] The present invention will be further explained below in combination with specific embodiments.

[0014] A combined motion control system for a marine hydraulic steering gear, including a transmitter, a receiver, a steering gear circuit, a servo motor, a reduction gear set, an actuator and a feedback resistor; the control signal sent by the transmitter is received by the receiver , separate the control signals of different channels, and then transmit them to the steering gear circuit. According to the signal, the steering gear circuit drives the action of the servo motor. The signal is fed back to the circuit for judgment. When the execution is in place, the circuit sends a signal to stop the rotation of the motor.

[0015] The steering gear circuit is arranged on the circuit board on the steering gear housing. The servo motor includes a coreless motor. The gears of the reduction gear set are plastic gears or metal gears. The control signal is PPM or PCM.

Abstract

The invention discloses a combined motion control system of a marine hydraulic steering gear. The combined motion control system of the marine hydraulic steering gear is characterized in that it includes a transmitter, a receiver, a steering gear circuit, a servo motor, a reduction gear set, an actuator and a feedback resistor; the control signal sent by the transmitter is controlled by The receiver receives and separates the control signals of different channels, and then transmits them to the steering gear circuit. The steering gear circuit drives the action of the servo motor according to the signal. At the same time, the action of the steering gear motor is decelerated by the reduction gear set to drive the actuator and the feedback resistor. , Feedback the angle signal to the circuit for judgment, when the execution is in place, the circuit sends a signal to stop the rotation of the motor. The combined motion control system of the marine hydraulic steering gear of the present invention has simple structure and ingenious design, and is a precision mechanism integrating electromechanical. The marine hydraulic steering gear is convenient, rapid and accurate to control, providing a good guarantee for safe driving.

Description

technical field [0001] The invention relates to a marine hydraulic steering gear, in particular to a combined motion control system of the marine hydraulic steering gear. Background technique [0002] A steering gear is a large deck machinery on a ship. At present, the marine steering gear is mostly electro-hydraulic, that is, the hydraulic equipment is remotely operated by the electric equipment. There are two types: one is the reciprocating plunger steering gear, its principle is to produce linear motion through the conversion of high and low pressure oil, and convert it into rotary motion through the tiller. The other is the rotary vane steering gear. Its principle is that the high and low pressure oil directly acts on the rotor. It is small in size and efficient, but the cost is relatively high. The difference between these two types of steering gear: the upper rudder bearing of the reciprocating plunger steering gear is used to bear the load of the rudder system, and ...
