Description

Technical Field

[0001] This utility model relates to the field of steering gear lubrication technology, specifically a high-efficiency and energy-saving steering gear transmission device for ships. Background Technology

[0002] The ship's steering gear is the core actuator of the ship's maneuvering system. Its function is to control the deflection of the rudder blades according to the driving commands, thereby changing the ship's course or maintaining a stable track. As a key device for ship navigation safety, the steering gear system is usually composed of a power unit, transmission mechanism, control unit and safety protection devices. In order to improve the transmission efficiency of the steering gear, some steering gears are equipped with heat dissipation mechanisms.

[0003] For example, the patent with authorization announcement number CN212063771U discloses a servo motor device that uses a motor to drive a fan to rotate, thereby causing air to flow inside the housing, achieving direct heat dissipation for the motor and transmission device, improving the heat dissipation effect of the servo motor, and increasing the service life of the servo motor. However, it has some shortcomings.

[0004] Firstly, the circulating air cooling method filters the air, but it cannot completely filter out moisture and dust. The residual moisture and dust will affect the service life of the gear set inside the servo motor. Moisture will accelerate its corrosion, and dust will accelerate its wear.

[0005] Secondly, the main sources of temperature inside the servo motor include heat generated by electrical operation and heat generated by mechanical friction. Air cooling can only reduce the temperature and cannot solve the root cause problem, such as the continuous heat dissipation between gear sets due to insufficient lubrication and increased friction. Utility Model Content

[0006] To address the aforementioned issues, this application provides a high-efficiency and energy-saving steering gear transmission device for ships, which solves the problems of the side effects of air cooling on gear sets and the inability to fundamentally resolve the issue of temperature rise.

[0009] The reservoir is used to store lubricating oil. Multiple stirring rods for stirring the lubricating oil are installed inside. A Hall effect sensor for detecting the rotation speed of the stirring rod is fixedly installed at the end of the top stirring rod. After the lubricating oil is heated to a suitable viscosity, the rotation speed of the stirring rod is increased to the set value.

[0010] The lubrication pump is fixedly installed on the top of the liquid storage tank and delivers lubricating oil through pipelines to the gears of the transmission gear set.

[0011] Preferably, a support chamber is fixedly installed on the top of the liquid storage tank, and an inlet and an outlet are opened through the outside of the support chamber. The heat dissipation pipe is connected to the inlet through a pipe. A spiral tube is fixedly installed inside the liquid storage tank. One end of the spiral tube is connected to the outlet through a pipe, and the other end of the spiral tube is connected to the liquid cooling unit body through a pipe.

[0012] Preferably, a drive shaft is rotatably mounted inside the levering chamber, and multiple blades are fixedly mounted on the outside of the drive shaft.

[0013] Preferably, an active friction plate is fixedly installed at the bottom of the drive shaft, a driven friction plate is fitted to the bottom of the active friction plate, an installation rod is fixedly installed at the bottom of the driven friction plate, the bottom of the installation rod is rotatably installed at the bottom of the inner side of the liquid storage tank, and the stirring rod is fixedly installed on the outer side of the installation rod.

[0014] Preferably, the temperature detection unit body is electrically connected to the liquid cooling unit body.

[0015] Preferably, the Hall effect sensor is electrically connected to the lubrication pump.

[0016] The beneficial effects of this utility model are as follows:

[0017] The present invention discloses a high-efficiency and energy-saving steering gear transmission device for ships, which adopts a liquid cooling method, preventing moisture and dust from entering the steering gear body and avoiding the phenomenon that the transmission gear set is affected by moisture and dust, thus shortening its service life.

[0018] Before adding the lubricating oil, it is heated and stirred to ensure that its lubrication effect is close to the optimal state. The lubrication pump delivers the lubricating oil between the gears, reducing the friction coefficient between the gears, thereby reducing heat generation, solving the high temperature problem at the root, and protecting the gears in time, extending the service life of the gears.

Detailed Implementation

[0027] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0028] First embodiment:

[0029] like Figures 1-5 As shown, this utility model embodiment provides a high-efficiency and energy-saving steering gear transmission device for ships, including a steering gear body 1, a transmission gear set 2 for transmission is provided on the inner side of the steering gear body 1, and a plurality of temperature detection unit bodies 3 for detecting the temperature inside the steering gear body 1 are installed on the inner side of the steering gear body 1.

[0030] The liquid cooling unit body 4 is installed on the outside of the servo body 1. The servo body 1 has heat dissipation pipes arranged on the inside. The coolant absorbs the heat inside the servo body 1 through the heat dissipation pipes. The temperature detection unit body 3 is electrically connected to the liquid cooling unit body 4.

[0031] In this embodiment, the temperature detection unit 3 detects the internal temperature of the servo motor body 1 in real time. When the temperature exceeds the set value, the temperature detection unit 3 sends an electrical signal to the data processor, and the data processor sends an electrical signal to the liquid cooling unit 4. The liquid cooling unit 4 is activated, and the coolant circulates in the servo motor body 1 to absorb heat and cool down. Liquid cooling is used to prevent moisture and dust from entering the servo motor body 1, thus avoiding the phenomenon that the transmission gear set 2 is affected by moisture and dust and has a shortened service life.

[0032] Second embodiment:

[0033] The difference from the above embodiments is that it also includes:

[0034] The storage tank 5 is used to store lubricating oil. Multiple stirring rods 15 for stirring the lubricating oil are installed inside. A Hall effect sensor 16 for detecting the rotation speed of the stirring rod 15 is fixedly installed at the end of the top stirring rod 15. After the lubricating oil is heated to a suitable viscosity, the rotation speed of the stirring rod 15 is increased to the set value.

[0035] Specifically, a booster compartment 7 is fixedly installed on the top of the liquid storage tank 5. An inlet 8 and an outlet 9 are provided through the outside of the booster compartment 7. The heat dissipation pipe is connected to the inlet 8 through a pipe. A spiral tube 17 is fixedly installed inside the liquid storage tank 5 for the flow of high-temperature coolant, thereby heating the lubricating oil. One end of the spiral tube 17 is connected to the outlet 9 through a pipe, and the other end of the spiral tube 17 is connected to the liquid cooling unit body 4 through a pipe.

[0036] In this embodiment, under cold conditions, the lubricating oil in the storage tank 5 is relatively viscous. The heated coolant enters from the inlet 8 and flows out from the outlet 9. Then, the high-temperature coolant flows through the spiral tube 17 to heat the lubricating oil, and then flows back to the inside of the liquid cooling unit body 4 for cooling and recycling.

[0037] Third embodiment:

[0038] The difference from the above embodiments is that it also includes:

[0039] The lubrication pump 6 is fixedly installed on the top of the liquid storage tank 5 and delivers lubricating oil through a pipeline to the gears of the transmission gear set 2. The Hall effect sensor 16 is electrically connected to the lubrication pump 6.

[0040] Specifically, a drive shaft 10 is rotatably mounted inside the lever hopper 7, and multiple blades 11 are fixedly mounted on the outside of the drive shaft 10 for absorbing the kinetic energy of the coolant.

[0041] In this embodiment, coolant enters from inlet 8 and flows out from outlet 9, driving drive shaft 10, blades 11, and active friction plate 12 to rotate.

[0042] Specifically, an active friction plate 12 is fixedly installed at the bottom of the drive shaft 10, a driven friction plate 13 is fitted to the bottom of the active friction plate 12, an installation rod 14 is fixedly installed at the bottom of the driven friction plate 13, the bottom of the installation rod 14 is rotatably installed at the bottom of the inner side of the liquid storage tank 5, and the stirring rod 15 is fixedly installed on the outer side of the installation rod 14.

[0043] In this embodiment, the temperature of the lubricating oil gradually increases and its viscosity decreases. The driven friction plate 13, mounting rod 14, stirring rod 15, and Hall effect sensor 16 rotate. When the Hall effect sensor 16 detects that the rotation speed of the stirring rod 15 reaches the set value, the lubrication effect of the lubricating oil is close to the optimal state. If the internal temperature of the servo motor body 1 decreases significantly under the action of the coolant, it indicates that there is no continuous large amount of heat generation and the lubricating oil between the transmission gear set 2 is sufficient. The liquid cooling unit body 4 stops working after a period of time. If the high temperature continues and the decrease is not significant, it indicates that the lubricating oil between the transmission gear set 2 needs to be replenished. The lubrication pump 6 starts to deliver lubricating oil between the gears, reduce the friction coefficient between the gears, and thus reduce heat generation, solving the high temperature problem from the root and protecting the gears in time, extending the service life of the gears.

[0044] Specific working methods:

[0045] The temperature detection unit 3 monitors the internal temperature of the servo motor body 1 in real time. When the temperature exceeds the set value, the temperature detection unit 3 sends an electrical signal to the data processor, which in turn sends an electrical signal to the liquid cooling unit 4. The liquid cooling unit 4 starts, and the coolant circulates within the servo motor body 1, absorbing heat and cooling down. The heated coolant enters through the inlet 8 and flows out through the outlet 9, driving the drive shaft 10, blades 11, and active friction plate 12 to rotate. Under cold conditions, the lubricating oil in the reservoir 5 is relatively viscous, and the rotational resistance of the stirring rod 15 is greater than the maximum friction force of the active friction plate 12 and the driven friction plate 13. The driven friction plate 13 does not rotate, and the high-temperature coolant flows through the spiral tube 17 to heat the lubricating oil. Then it flows back to the inside of the liquid cooling unit 4 for cooling and recycling. Liquid cooling prevents moisture and dust from entering the servo motor body 1, thus avoiding the phenomenon that the transmission gear set 2 is affected by moisture and dust, which shortens its service life.

[0046] As the temperature of the lubricating oil gradually increases and its viscosity decreases, the driven friction plate 13, mounting rod 14, stirring rod 15, and Hall effect sensor 16 rotate. When the Hall effect sensor 16 detects that the rotation speed of the stirring rod 15 has reached the set value, the temperature of the lubricating oil is suitable. At the same time, stirring makes its composition uniform, and the lubrication effect is close to the optimal state. If the internal temperature of the servo motor body 1 decreases significantly under the action of the coolant, it indicates that there is no continuous large amount of heat generation and the lubricating oil between the transmission gear set 2 is sufficient. The liquid cooling unit body 4 stops working after a period of time. If the high temperature continues and the decrease is not significant, it indicates that the lubricating oil between the transmission gear set 2 needs to be replenished. The lubrication pump 6 starts to deliver lubricating oil between the gears, reduce the friction coefficient between the gears, and thus reduce heat generation, solving the high temperature problem at the root and protecting the gears in time, extending the service life of the gears.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
