Description

Technical Field

[0001] The present invention belongs to the technical field of ship propulsion, and particularly relates to a motor propulsion shafting structure of a podded propeller applicable to ice area ships. Background Art

[0002] A ship propeller is an important component in the power equipment of ice area ships. The motor propulsion shafting structure is the core component of the power transmission system of the podded propeller, and its design directly affects the power transmission efficiency and equipment stability.

[0003] For example, the publication number is: CN218431703, which discloses a motor propulsion shafting structure and a podded propeller for a podded propeller. The motor propulsion shafting structure includes a motor assembly, a thrust end assembly, and a propeller side end assembly. The motor assembly includes a rotor part and a stator part, and the stator part is configured to drive the rotor part to rotate; the thrust end assembly includes a thrust side shaft, and one end of the thrust side shaft is detachably connected to one end of the rotor part; the propeller side end assembly includes a propeller side shaft, and one end of the propeller side shaft is connected to the end of the rotor part away from the thrust side shaft; the rotor part, the thrust side shaft, and the propeller side shaft are coaxially arranged. The motor propulsion shafting structure of the podded propeller of the present invention adopts a segmented structure, divides the overall shafting into three independent axial connecting parts, namely the rotor part, the thrust side shaft, and the propeller side shaft, which is easy to disassemble, install and repair, avoids vibrations, noises and other situations caused by shafting deformation, and ensures the safety performance of the podded propeller.

[0004] When the motor propulsion shafting structure of the podded propeller is in use, although it adopts a segmented structure and is easy to disassemble, install and repair, it is inconvenient to manually fix the bearing through the bearing end cover, which is time-consuming and laborious. Moreover, after long-term operation, the bearings at one end of the motor rotating shaft and the propeller side shaft have too high temperatures. If heat dissipation is not carried out, it will affect its normal use. The prior art generally dissipates heat through heat dissipation holes, and the heat dissipation effect is poor. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to solve the above problems in the prior art, and provide a motor propulsion shafting structure of a podded propeller applicable to ice area ships, so as to achieve the purpose of quickly fixing the bearing and improving the heat dissipation effect of the bearing.

[0006] The present invention adopts the following technical solutions to achieve:

[0007] Pod propeller motor propulsion shafting structure applicable to ice area ships, including a first motor and a mounting seat. A rotating shaft is fixedly installed at the output end of the first motor. One end of the rotating shaft is installed with a propeller side shaft through a coupling. One end of the propeller side shaft is fixedly installed with a propeller. An installation groove is opened at one end of the mounting seat. A bearing is inserted into the installation groove. The rotating shaft and the propeller side shaft are both installed inside the bearing. Both ends of the mounting seat are installed with movable arc-shaped fixing plates through a driving component. One end of the arc-shaped fixing plate is in close contact with the bearing. A support plate is fixedly installed on one side of the mounting seat. A heat dissipation component for dissipating heat from the bearing is installed at the upper end of the support plate. When in use, the arc-shaped fixing plate is used to fix the bearing, and the driving component is used to move the arc-shaped fixing plate. The coupling is a conventional structure for connecting the rotating shaft and the propeller side shaft.

[0008] To optimize the above technical solution, the specific measures taken also include:

[0009] Further, in order to make the arc-shaped fixing plate move smoothly, sliding grooves are opened at both ends inside the installation groove. The arc-shaped fixing plate is slidably installed in the sliding grooves, and the arc-shaped fixing plate can move in the sliding grooves.

[0010] Further, in order to increase the friction between the arc-shaped fixing plate and the bearing, an anti-slip pad is fixedly installed at one end of the arc-shaped fixing plate. The anti-slip pad is made of rubber material.

[0011] Further, in order to enable the arc-shaped fixing plate to move, the driving component includes a threaded rod. The threaded rod is threadedly connected to both ends of the mounting seat. One end of the threaded rod is rotatably connected to the arc-shaped fixing plate. The threaded rod is used to change the position of the arc-shaped fixing plate.

[0012] Further, in order to facilitate the rotation of the threaded rod, a handwheel is fixedly installed at one end of the threaded rod.

[0013] Further, in order to dissipate heat from the bearing, a ring plate is fixedly installed at one end of the bearing. A plurality of heat dissipation holes are arranged in a circumferential array at one end of the ring plate.

[0014] Further, in order to convey cold air into the bearing, the heat dissipation component includes a cold air blower and an air outlet cover. The air outlet cover is fixedly installed on one side of the mounting seat. One end of the air outlet cover is communicated with the heat dissipation holes.

[0015] Furthermore, in order to convey cold air into the air outlet hood, the air cooler is fixedly installed on the support plate. An air delivery pipe is fixedly installed at the output end of the air cooler. An L-shaped pipe is fixedly installed at one end of the air outlet hood. One end of the L-shaped pipe is communicated with the air delivery pipe. The air cooler is used to convey cold air, and the control end of the air cooler is electrically connected to the control module of the pod thruster.

[0016] Advantages of the present invention:

[0017] When the present invention is in use, by manually rotating the threaded rod, the arc-shaped fixing plate fixes the bearing, which is convenient, fast, time-saving and labor-saving. It is also possible to dissipate heat from the bearing by conveying cold air into the heat dissipation holes, quickly cool down the bearing, improve the heat dissipation effect, and prevent the internal temperature of the bearing from being too high to affect its normal use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to clarify the technical solution and working principle of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0026] Please refer to Figures 1-6 As shown, the podded propeller motor propulsion shafting structure applicable to ice area ships includes a first motor 1 and a mounting seat 2. A rotating shaft 9 is fixedly installed at the output end of the first motor 1. One end of the rotating shaft 9 is installed with a propeller side shaft 10 through a coupling. One end of the propeller side shaft 10 is fixedly installed with a propeller 11. An installation groove 3 is opened at one end of the mounting seat 2. A bearing 4 is inserted into the installation groove 3. Both the rotating shaft 9 and the propeller side shaft 10 are installed inside the bearing 4. Both ends of the mounting seat 2 are installed with movable arc-shaped fixing plates 6 through a driving component 5. One end of the arc-shaped fixing plate 6 is in close contact with the bearing 4. A support plate 7 is fixedly installed on one side of the mounting seat 2. A heat dissipation component 8 for dissipating heat from the bearing 4 is installed at the upper end of the support plate 7. Sliding grooves 12 are opened at both ends inside the installation groove 3. The arc-shaped fixing plate 6 is slidably installed in the sliding grooves 12. An anti-slip pad 13 is fixedly installed at one end of the arc-shaped fixing plate 6. The anti-slip pad 13 is made of rubber. A circular plate 14 is fixedly installed at one end of the bearing 4. Heat dissipation holes 15 are arranged in a circumferential array at one end of the circular plate 14. When in use, first fixedly install the mounting seat 2 at the corresponding position, then respectively fixedly install the rotating shaft 9 and the propeller side shaft 10 inside the bearing 4, then connect the rotating shaft 9 and the propeller side shaft 10 together through a coupling, then install the bearing 4 into the installation groove 3 at one end of the mounting seat 2, and then manually move the arc-shaped fixing plate 6 through the driving component 5 to fix the bearing 4, which is convenient, fast, time-saving and labor-saving. At this time, the arc-shaped fixing plate 6 moves in the sliding grooves 12, so that the arc-shaped fixing plate 6 can move smoothly without deviation. At the same time, the anti-slip pad 13 at one end of the arc-shaped fixing plate 6 can increase the friction between the arc-shaped fixing plate 6 and the bearing 4 to prevent slipping. After fixing the bearing 4, start the first motor 1 to drive the rotating shaft 9 to rotate, and the propeller side shaft 10 rotates accordingly, so that the propeller 11 rotates circumferentially to propel the ship to move. After working for a period of time, start the heat dissipation component 8 to dissipate heat from the bearing 4. By delivering cold air into the heat dissipation holes 15 at one end of the circular plate 14, the inside of the bearing 4 can be quickly cooled, and the heat dissipation effect is good, preventing the internal temperature of the bearing 4 from being too high and affecting its normal use.

[0027] The driving component 5 includes a threaded rod 501. The threaded rod 501 is threadedly connected to both ends of the mounting seat 2. One end of the threaded rod 501 is rotatably connected to the arc-shaped fixing plate 6. A handwheel 502 is fixedly installed at one end of the threaded rod 501. When in use, manually rotate the handwheel 502 to drive the threaded rod 501 to rotate, so that the arc-shaped fixing plate 6 moves to one side in the sliding grooves 12 to fix the bearing 4, which is convenient, fast, time-saving and labor-saving. When the bearing 4 needs to be replaced, rotate the handwheel 502 in the reverse direction, and the threaded rod 501 rotates in the reverse direction accordingly, so that the arc-shaped fixing plate 6 resets to release the fixing effect on the bearing 4, and then the bearing 4 can be taken out.

[0028] The heat dissipation component 8 includes a cooling fan 801 and an air outlet cover 802. The air outlet cover 802 is fixedly installed on one side of the mounting base 2. One end of the air outlet cover 802 is communicated with the heat dissipation hole 15. The cooling fan 801 is fixedly installed on the support plate 7. A duct 803 is fixedly installed at the output end of the cooling fan 801. An L-shaped pipe 804 is fixedly installed at one end of the air outlet cover 802. One end of the L-shaped pipe 804 is communicated with the duct 803. When in use, when it is necessary to dissipate heat from the bearing 4, manually start the cooling fan 801. The cold air generated by the cooling fan 801 is transported to the L-shaped pipe 804 through the duct 803, and then transported to the air outlet cover 802 through the L-shaped pipe 804, and then transported to the inside of the bearing 4 through the heat dissipation hole 15 at one end of the annular plate 14 for cooling, and the hot air inside the bearing 4 is quickly discharged through the heat dissipation hole 15 at the other end, preventing the temperature inside the bearing 4 from being too high and affecting its normal use.
