Hereinafter, being illustrated with a kind of specific embodiment, it should be pointed out that described in following implementation it
Structure, technique, selection are only to illustrate the feasibility of embodiment, the intention of scope of protection of the utility model that there is no restriction.
A kind of working principle of the rudder hydraulic drive mechanism based on ball-type motion pair：Steering hydraulic cylinder 1 passes through connection
Pin 3 drives steering arm 2 to rotate around steering straight-bar 4, and steering arm 2 and steering straight-bar 4 are rigidly connected, and steering straight-bar 4 surrounds
Own axes also rotate, and steering straight-bar 4 and steering crank 5 are rigidly connected, and steering crank 5 follows steering straight-bar 4 to revolve
Turning, steering crank 5 and rudder 6 are slidably connected, in the ball cup of the bulb direction of insertion rudder 6 of steering crank 5, steering crank 5
Rotation drives rudder 6 also to deflect, since the rotation center of rudder 6 is fixed setting, so rudder 6 cannot occur
Around the rotation of 4 shaft centre line of steering straight-bar, can only rotate in the horizontal plane around 6 rotation center of rudder, rudder 6 exists
When horizontal deflecting facet ball cup can generate rotation and with the equidirectional linear motion of steering straight-bar 4, this linear motion can transmit
To steering crank 5, steering straight-bar 4 and steering arm 2.The deflection angle of rudder 6 is bigger, and the rotation angle of steering crank 5 is also got over
Greatly, the displacement of linear motion is also bigger.It can be seen that from implementation process, by being slidably connected at bulb 51, bulb 51 and bulb
Contact surface at seat 61 constantly changes, and realizes rudder 6 being converted to behaviour in the rotary motion of the single-degree-of-freedom of horizontal plane
The two degree-of-freedom motion that rudder crank 5, the rotary motion of steering straight-bar 4 and steering arm 2 and linear motion combine.
A kind of rudder hydraulic drive mechanism based on ball-type motion pair provided in this embodiment, the one of steering hydraulic cylinder 1
End offers mounting hole 1, and the section of steering arm 2 is concave setting, and the lateral wall of 2 upper end of steering arm is provided with two peaces
