Embodiment 1
[0035] figure 1 It is a structural diagram showing the main parts of the steering gear for ships according to the first embodiment of the present invention, (A) is a structural diagram when the hydraulic cylinder is neutral, and (B) is a structural diagram when the hydraulic cylinder is in operation (partial representation of the hydraulic cylinder is omitted).
[0036] exist figure 1 In (A) and (B), the rod-shaped slider shaft arranged on the same axis in the stationary state is bisected in the axial direction by the shaft end faces 1s, 1s at right angles to the axis 1a of the slider shaft. Divided into the first slider axis 1z and the second slider axis 1y. The cylindrical body 12 rotatably supported by the slider pin 4 is in contact with the shaft end surfaces 1s, 1s of the first slider shaft 1z and the second slider shaft 1y.
[0037] The slider pin 4 rotatably supports the above-mentioned cylindrical body 12 , and both ends of the slider pin 4 are fixed to the fork-sh...
Embodiment 2
[0048] figure 2 It is an enlarged view showing the structure of a main part of a steering gear for ships according to a second embodiment of the present invention.
[0049] This second embodiment is the same as the implementation of the first embodiment. The rod-shaped slider shaft arranged on the same axis in the static state is aligned in the axial direction through the shaft end faces 1s, 1s at right angles to the axis 1a of the slider shaft. It is bisected and divided into a first slider axis 1z and a second slider axis 1y.
[0050] In addition, a rolling bearing 14a is provided, and the outer ring 14 is rotatably in contact with the shaft end surfaces 1s, 1s of the divided parts of the first slider shaft 1z and the second slider shaft 1y, so that the rotation of the outer ring 14 passes through the rolling elements (multiple A ball or a roller body) 15 is connected to the inner ring 12a, and the inner ring 12a of the above-mentioned rolling bearing 14a is freely rotatab...
Embodiment 3
[0055] image 3 It is a configuration diagram of main parts of a steering gear for ships showing a third embodiment of the present invention.
[0056] This third embodiment is the same as the above-mentioned first embodiment, and the rod-shaped slider shaft arranged on the same axis in the static state is arranged in the axial direction through the shaft end faces 1s, 1s at right angles to the axis 1a of the slider shaft. It is bisected and divided into a first slider axis 1z and a second slider axis 1y.
[0057] And, in this third embodiment, between the first slider shaft 1z and the second slider shaft 1y that bisect the above-mentioned slider shaft, the first slider shaft 1z and the second slider shaft 1y are formed by welding pairs. The block shaft 1y is fixed to the reinforcing plate 16 connected so that it cannot move relative to each other (it may also be screwed).
[0058] In addition, in this third embodiment, there is provided a stopper 8a fixed on the above-mentio...

Abstract
Provided is a steering machine, capable of reducing the friction resistance of a slide block shaft when a rudder angle of a rudder axle is bigger and improving the whole mechanical efficiency of the steering machine. The steering machine comprises a shaft driven to and fro, a buckling member buckled with the slide block shaft, and a rotation driving mechanism connected with the buckling member for changing the reciprocation of the slide block shaft into the rotation to rotate and drive the rudder axle, characterized in that the slide block shaft is divided into a first slide block shaft (1z) and a second slide block shaft (1y) at an right angle with an axis in the bisection way, so that the buckling member is formed into a cylinder (12) freely rotatablely abutted against a shaft end face (1s) of a dividing part of the first slide block shaft and the second slide block shaft, and a rudder stock (2) is provided, and freely rotatablely supports the cylinder (12) and drives the rudder axle to rotate by the rotation of the cylinder caused by the reciprocation of the first slide block shaft and the second slide block shaft.
Description
technical field [0001] The invention relates to a steering gear for ships, which has: a slider, which is reciprocally driven by a fluid pressure cylinder such as an oil pressure cylinder; a fastening part, which can be fastened with the slider; connected to change the reciprocating motion of the above-mentioned slide block into a rotary motion to rotate and drive the rudder shaft. Background technique [0002] Figure 5 It is a plan view of main parts of a steering gear for ships shown in Patent Document 1 (Japanese Publication No. 3-56479). [0003] exist Figure 5 Among them, a rod-shaped slider shaft 1 is disposed on the same axis, and both ends of the slider shaft 1 are supported by bearings 11, 11 of hydraulic cylinders 6, 6 installed on hulls 5, 5, and are housed in the Inside the hydraulic cylinders 6, 6, the slider shaft 1 is driven to reciprocate on the same axis by the hydraulic pressure of the hydraulic cylinders 6, 6. [0004] A slider pin 4 protrudes from the ...
