Description

Technical Field

[0001] This utility model relates to the field of hydraulic motor technology, and in particular to a variable cycloidal hydraulic motor that is easy to adjust. Background Technology

[0002] A cycloidal hydraulic motor is a low-speed, high-torque hydraulic motor driven by pressurized oil and based on the principle of cycloidal meshing. Its core components are the internal cycloidal wheel (rotor) and the outer ring fixed pin teeth (stator) that mesh with it. When high-pressure oil enters the motor chamber, it acts on the tooth profile surface of the cycloidal wheel. Due to the special meshing relationship between the tooth profile curve of the cycloidal wheel and the fixed pin teeth, under hydraulic push, the cycloidal wheel does not rotate directly around its own center like an ordinary gear, but generates a compound planetary motion that both rotates on its own axis and revolves relative to the center of the pin tooth ring. Existing cycloidal hydraulic motors typically use fins added to the motor for heat dissipation, but the heat dissipation efficiency is low and the heat dissipation rate cannot be controlled. Too fast or too slow heat dissipation will affect the motor's operation and may also damage the motor, failing to meet the needs of operators. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an easily adjustable variable cycloidal hydraulic motor.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An easily adjustable variable cycloidal hydraulic motor includes a motor body, a control box fixedly mounted on the motor body, multiple cooling pipes fixedly mounted on the control box, all of which are fixedly installed inside the motor body, a liquid inlet on the control box, a rotary motor fixedly mounted inside the control box, a threaded rod one fixedly mounted on the output shaft of the rotary motor, a moving block threadedly connected to the threaded rod one, a threaded rod two rotatably mounted inside the control box matching the multiple cooling pipes, a baffle threadedly connected to the threaded rod two, a spur gear fixedly mounted on the threaded rod two, a rack fixedly mounted on the moving block, the spur gear meshing with the rack, and a second cooling assembly mounted on the motor body.

[0005] Preferably, the second cooling assembly includes multiple fins fixedly mounted on the motor body, a support frame fixedly mounted on the lower end of the motor body, a rotating motor fixedly mounted on the support frame, two air vents on the support frame, a rotating shaft rotatably mounted inside the air vents, multiple fan blades fixedly mounted on the rotating shaft, and the rotating shaft connected to the output shaft of the rotating motor via a belt drive assembly.

[0006] Preferably, a temperature sensor is fixedly installed inside the motor body.

[0007] Preferably, a slide bar is fixedly installed inside the control box, and the moving block is slidably connected to the slide bar.

[0008] Preferably, the rotating motor is made of a high-temperature resistant material.

[0009] Preferably, a plurality of limit rods are fixedly installed inside the control box, and the baffle is slidably connected to the limit rods.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. By installing cooling pipes and inputting cold water, the heat dissipation efficiency can be further improved even with finned heat dissipation. At the same time, by opening and closing the number of cooling pipes, the flow rate of cooling water can be controlled, thereby achieving the effect of regulating the cooling rate, making the cooling rate moderate, and saving energy and reducing consumption.

[0011] 2. At the same time, fan blades are provided at the lower end of the fins. The air force generated by the fan blades can accelerate the heat conduction efficiency of the fins and further improve the heat dissipation efficiency, thus meeting the needs of the staff.

Detailed Implementation

[0017] Reference Figures 1-4 An easily adjustable variable cycloidal hydraulic motor, comprising: Motor body 1, which is existing technology, is a cycloidal hydraulic motor, a low-speed, high-torque hydraulic motor driven by pressurized oil and operating based on the cycloidal meshing principle. Its core components are the internal cycloidal wheel and the outer ring of fixed pin teeth that mesh with it. When high-pressure oil enters the motor chamber, it acts on the tooth profile of the cycloidal wheel. Due to the special meshing relationship between the tooth profile curve of the cycloidal wheel and the fixed pin teeth, under hydraulic pressure, the cycloidal wheel does not rotate directly around its own center like ordinary gears, but instead produces a composite planetary motion that both rotates on its own axis and revolves relative to the center of the pin tooth ring. A control box 2 is fixedly installed on the motor body 1. Multiple cooling pipes 3 are fixedly installed on the control box 2. All cooling pipes 3 are fixedly installed inside the motor body 1. The control box 2 has a liquid inlet 4. A rotary motor 5 is fixedly installed inside the control box 2. A threaded rod 6 is fixedly installed on the output shaft of the rotary motor 5. A moving block 7 is threadedly connected to the threaded rod 6. A threaded rod 8 that matches the multiple cooling pipes 3 is rotatably installed inside the control box 2. A baffle 9 is threadedly connected to the threaded rod 8. A spur gear 10 is fixedly installed on the threaded rod 8. A rack 11 is fixedly installed on the moving block 7. The spur gear 10 meshes with the rack 11. A second cooling component is installed on the motor body 1. By setting a control box 2 on the motor body 1, coolant is delivered to the control box 2 through the liquid inlet 4. The coolant flows in the motor body 1 through the cooling pipe 3 and is discharged from the other end. The tail end of the cooling pipe 3 is connected to a collection pipe. By starting the rotary motor 5, the threaded rod 6 is rotated, which can drive the moving block 7 to move. At this time, the rack 11 on the moving block 7 will move. When the rack 11 contacts the spur gear 10, it drives the spur gear 10 to rotate, which can drive the threaded rod 8 to rotate, so that the baffle 9 can move up and down. This can complete the switching of the cooling pipe 3, thereby realizing the flow control. The second cooling assembly includes multiple fins 12 fixedly mounted on the motor body 1. A support frame 13 is fixedly mounted on the lower end of the motor body 1. A rotating motor 14 is fixedly mounted on the support frame 13. Two air vents are opened on the support frame 13. A rotating shaft 15 is rotatably mounted inside the air vents. Multiple fan blades 16 are fixedly mounted on the rotating shaft 15. The rotating shaft 15 is connected to the output shaft of the rotating motor 14 through a belt drive assembly 17. By starting the rotating motor 14, the belt drive assembly 17 is driven to rotate, which in turn drives the rotating shaft 15 to rotate, thereby driving the fan blades 16 to rotate, thus generating wind power, which can blow air onto the fins 12 and accelerate the heat conduction efficiency. A temperature sensor is fixedly installed inside the motor body 1. The temperature sensor can detect the internal temperature, thereby effectively adjusting the cooling pipe 3. A slide rod 18 is fixedly installed inside the control box 2. The moving block 7 is slidably connected to the slide rod 18. The slide rod 18 serves a limiting function, allowing the moving block 7 to move stably without shaking. The rotating motor 14 is made of high-temperature resistant material, which can effectively prevent high temperatures from affecting the rotating motor 14 and improve its service life. Multiple limit rods are fixedly installed inside the control box 2. The baffle 9 is slidably connected to the limit rods. The limit rods serve a stabilizing function, preventing the baffle 9 from shifting and failing to cover the cooling pipe 3.

[0018] The working principle of this invention is as follows: A control box 2 is installed on the motor body 1. Coolant is delivered to the control box 2 through the liquid inlet 4. The coolant flows through the cooling pipe 3 in the motor body 1 and is discharged from the other end. The tail end of the cooling pipe 3 is connected to a collection pipe. By starting the rotary motor 5, the threaded rod 6 is rotated, which in turn moves the moving block 7. At this time, the rack 11 on the moving block 7 is moved. When the rack 11 contacts the spur gear 10, it drives the spur gear 10 to rotate, which in turn drives the threaded rod 8 to rotate, causing the baffle 9 to move up and down. This completes the switching operation of the cooling pipe 3, thereby achieving flow control. By starting the rotary motor 14, the belt drive assembly 17 is rotated, which in turn drives the rotating shaft 15 to rotate, which in turn drives the fan blade 16 to rotate, thereby generating wind power to blow air onto the fins 12 and accelerate the heat conduction efficiency.
