Abstract
Description
Technical Field
[0001] The utility model relates to a rudder system structure, in particular to a novel rudder system structure. Background Art
[0002] The rudder system is a key component for controlling a ship's direction, typically consisting of a rudder, a tiller, a steering gear, and related control systems. In the steering mechanism, which consists of a hydraulic cylinder and a tiller, the sliding portion of the slider requires lubrication to reduce friction and wear, thereby improving system reliability and lifespan.
[0003] Existing automatic lubrication systems typically rely on multiple sensors and complex control systems to monitor the equipment's operating status and trigger lubrication. These sensors and control systems increase system complexity, potentially leading to higher costs and increased maintenance requirements. Furthermore, complex electronic control systems are susceptible to environmental factors such as electromagnetic interference and temperature fluctuations, which can cause system failures, delay lubricant replenishment when needed, and lead to equipment wear. Utility Model Content
[0004] In order to overcome the above-mentioned shortcomings, the technical problem of the present invention is to provide a new rudder system structure.
[0005] Technical solution: A new rudder system structure, including a rudder blade, a rudder arm, a rudder stock, a rudder bearing seat, a steering wheel, a slider, a telescopic rod, a hydraulic cylinder, a support seat and a lubrication assembly. The lower end of the rudder stock is connected to the rudder blade, and the lower end of the rudder stock is rotatably connected to the rudder arm installed at the stern. The upper end of the rudder stock is rotatably connected to the rudder bearing seat fixed to the hull. Support seats fixed to the hull are distributed on both sides of the rudder bearing seat. Hydraulic cylinders are installed on both sides between the tops of the support seats. The hydraulic cylinders are series cylinders, and two cylinders are connected together through a common telescopic rod. The upper end of the rudder stock is connected to the steering wheel, and the front and rear sides of the steering wheel are slidably connected to sliders.

DETAILED DESCRIPTION
[0019] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the present invention are shown. However, the present invention can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art.
[0020] Example: A new rudder system structure, such as Figures 1-6 As shown, it includes a rudder blade 1, a rudder hanging arm 2, a rudder stock 3, a rudder bearing seat 4, a steering wheel 5, a slider 6, a telescopic rod 7, a hydraulic cylinder 71, a support seat 72 and a lubrication assembly. The lower end of the rudder stock 3 is connected to the rudder blade 1, and the lower end of the rudder stock 3 is rotatably connected to the rudder hanging arm 2 installed at the stern. The upper end of the rudder stock 3 is rotatably connected to the rudder bearing seat 4 fixed to the hull. Support seats 72 fixed to the hull are distributed on the left and right sides of the rudder bearing seat 4. Hydraulic cylinders 71 are installed on the front and rear sides between the tops of the support seats 72. The hydraulic cylinders 71 are tandem cylinders, which are connected together by a common telescopic rod 7. The upper end of the rudder stock 3 is connected to the steering wheel 5. The front and rear sides of the steering wheel 5 are slidably connected to the slider 6. The slider 6 is rotatably connected to the telescopic rod 7 on the same side. Oil holes 13 are opened in the sliders 6. The oil holes 13 are a double cross structure. The oil holes 13 of the cross structure pass through the connection between the upper and lower ends of the slider 6 and the rudder stock 3. A lubrication assembly is provided on the top of the rudder stock 3.
[0021] like Figure 1-Figure 5 As shown, the lubrication assembly includes an oil storage tank 8, a one-way oil outlet valve 9, a piston cylinder 10, a connecting pipe 11, a one-way valve 12, a dust cover 14 and a transparent plate 15. The top of the rudder bar 3 is connected to the oil storage tank 8, and the front and rear sides of the oil storage tank 8 are connected to the one-way oil outlet valve 9. The one-way oil outlet valve 9 is connected to the piston cylinder 10. The piston cylinder 10 is slidably connected with a connecting pipe 11, and the upper end of the connecting pipe 11 is installed with a one-way valve 12. The lower end of the connecting pipe 11 is connected to the slider 6 on the same side and communicates with the oil hole 13 to facilitate the lubricating oil to flow into the connection between the slider 6 and the steering wheel 5. A dust cover 14 for dust prevention and oxidation prevention is clamped at the discharge port on the top of the oil storage tank 8. A transparent plate 15 for checking the oil amount is connected to the left side of the oil storage tank 8.
[0022] like Figure 2 As shown, a scale 16 and a pointer 17 are also included. The pointer 17 is welded to the front side of the front telescopic rod 7, and the scale 16 is welded between the top front sides of the rudder support seat 4. The pointer 17 points to the scale 16, and the pointer 17 moves with the telescopic rod, so that the steering angle of the rudder blade 1 can be easily known through the scale 16.
[0023] The rudder system structure is a key part of the ship for controlling the direction. The rudder bearing seat 4 and the support seat 72 are installed at the stern, the rudder arm 2 is installed below the stern, and the rudder blade 1 is adjacent to the back of the propeller. The deflection of the rudder blade 1 in the water can generate lateral force, thereby changing the heading of the ship.
[0024] First, open the dust cover 14 and fill the oil tank 8 with lubricating oil. When the boat is in use, the driver sends a steering command through the steering wheel 5 in the cab. This command is transmitted to the steering gear control system through mechanical or electrical signals. After receiving the command, the steering gear control system will start the hydraulic cylinder 71. After the hydraulic oil enters the cylinder, it pushes the telescopic rod 7 to move to the left or right. The movement directions of the front and rear telescopic rods 7 are opposite. When the telescopic rod 7 moves, it pushes the slider 6 to move synchronously, thereby driving the rudder bar 3 to rotate. The angle change of the rudder bar 3 causes the slider 6 to slide along the steering wheel 5, and the components on the rudder bar 3 also rotate accordingly, thereby driving the rudder blade 1 to deflect a certain angle in the water. Due to the force of the water flow on the deflected rudder blade 1, the hull will change direction accordingly. When the front telescopic rod 7 moves, it drives the pointer 17 to move synchronously. The pointer 17 points to the scale 16. By checking the value on the scale 16 pointed by the pointer 17, the steering angle of the rudder blade 1 can be known.
[0025] When the slider 6 rotates with the rudder stock 3, the connecting pipe 11 will be driven to move. As the angle changes, the connecting pipe 11 slides outward in the piston cylinder 10, and then the lubricating oil in the oil storage tank 8 is pumped by the internal pressure. The lubricating oil is pumped into the piston cylinder 10 through the one-way oil outlet valve 9. When the slider 6 is turned in the other direction by the thrust of the telescopic rod 7, the connecting pipe 11 slides toward the inside of the piston cylinder 10, squeezing the lubricating oil in the piston cylinder 10. Under the action of the one-way oil outlet valve 9, the lubricating oil will not flow back into the oil storage tank 8, but enter the connecting pipe 11 through the one-way valve 12, and then flow along the oil hole 13 to the connection between the slider 6 and the rudder stock 3, thereby achieving the purpose of automatic lubrication.
[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
