摘要： An electric actuator comprises a housing and an output shaft reciprocatingly received by the housing. There is a screw assembly disposed within the housing and coupled to the output shaft. The screw assembly includes a plurality of annular rollers and a central screw received by the annular rollers. The annular rollers are rotatable about the central screw. There is a motor which includes a stator and a rotor. The rotor has an inner bore which engages the annular rollers. Rotation of the rotor causes the central screw to translate axially relative to the rotor and the output shaft to reciprocate relative to the housing.

摘要： A steering system (1) installed in a ship includes: a hydraulic actuator (2) that turns a rudder plate (11) via a rudder stock (12) that penetrates a ship bottom; and a pump (41) that delivers hydraulic oil. A first actuating chamber (22) and a second actuating chamber (23) of the hydraulic actuator are connected to a switching valve (3) by a pair of supply/discharge lines (44, 45). The switching valve (3) is connected to the pump (41) by a pump line (42). The switching valve (3) includes a spool (31). The spool (31) is shifted by a shifting mechanism (5). The shifting mechanism (5) is configured such that a shifting speed of the spool (31) is electrically changeable.

摘要： Support arms (40, 41) are disposed on a tilting shaft (32) on a bracket (30) of an outboard motor. An electric actuator (50) is mounted between the support arms (40, 41). The electric actuator (50) includes a cover member (51), first and second electric motors (52, 53) disposed individually on the opposite ends of the cover member (51), a feed screw (54) configured to be rotated by the electric motors (52, 53), a nut member (70) configured to move along an axis (X1) as the feed screw (54) rotates, a drive arm (71) configured to move integrally with the nut member (70) and transversely relative to the boat body (11), and protective boots (80, 81). The drive arm (71) is connected to a steering arm (35) through an engaging member (73). If the drive arm (71) moves in the direction of the axis (X1) along the cover member (51), the steering angle of the steering arm (35) changes depending on the degree of movement of the drive arm (71).

摘要： A steering apparatus comprises a rotatable steering shaft and a sensor which senses angular movement of the steering shaft. An electromagnetic actuator actuates a stop mechanism to releasable engage the steering shaft. There is a microcontroller which causes the electromagnetic actuator to actuate the stop mechanism to fully engage the steering shaft and prevent rotation of the steering shaft in a first rotational direction, which corresponds to movement towards the hardstop position, while allowing rotational play between the steering shaft and the stop mechanism in a second direction, which corresponds to rotational movement away from the hardstop position, when the sensor senses that the steering shaft has reached a hardstop position. A driver applies a reserve polarity pulse to the electromagnetic actuator when the stop mechanism is fully engaged and the steering shaft is rotated, as permitted by the rotational play, in the second rotational direction.

摘要： To allow plural AC servo motors of an electric turning control unit to share load equally.
A turning control unit 2 for controlling a freely turnable marine propulsion machine includes: a turning control board 7 which calculates a digital motor-speed reading from a deviation between a signal from a sensor 6 for detecting a turning position of the marine propulsion machine and a handle signal; and a plurality of AC servo amplifiers A1, A2 which drive AC servo motors M1, M2 by receiving the motor-speed reading from the turning control board and outputting a motor speed command value. Each amplifier is adapted to reduce the motor speed command value according to a load amount when the motor performs power running, to increase the motor speed command value according to the load amount when the motor performs regenerative running, and to make no correction when the load amount of the motor is equal to or less than a fixed value. The respective loads on the plural AC servo motors can be dispersed to a uniform value.
