[0021] Figure 1 It is a structural schematic diagram of the oil circulation structure of the transmission case in the embodiment of the utility model.

[0022] like Figure 1 As shown, the oil circulation structure of the speed-up box provided by the utility model includes a circulation pipeline 10, a rectifying and pressure-regulating assembly 20, and a speed-up box 30. The speed-up box 30 is arranged on the circulation pipeline 10, and oil is arranged in the circulation pipeline 10. The oil circulates in the circulation pipeline 10. The rectifying and pressure-regulating assembly 20 is arranged on the circulation pipeline 10. The rectifying and pressure-regulating assembly 20 can adjust the pressure and flow of the oil, so that the oil can flow within the rated range of pressure and flow, ensure the normal operation of the speed-up box 30, improve the reliability of the speed-up box 30, extend the service life of the speed-up box 30, and help ensure the continuous and reliable operation of the speed-up box 30, and save energy and reduce emissions. A circulation pump 11 is arranged on the circulation pipeline 10, and the circulation pump 11 can pump oil, so that the oil can circulate in the circulation pipeline 10, and ensure the normal operation of the speed-up box 30.

[0023] The rectifier and pressure regulating assembly 20 includes a frequency converter 21, a pressure transmitter 22 and a flow transmitter 23. The frequency converter 21 is connected to the circulation pump 11. The frequency converter 21 can adjust the speed of the motor in the circulation pump 11, thereby adjusting the pressure and flow of the oil pumped by the circulation pump 11. The pressure transmitter 22 is arranged on the circulation pipeline 10, located on one side of the outlet of the circulation pump 11. The pressure transmitter 22 is a sensor that converts a pressure signal into an electric signal, and can monitor the pressure of the oil at the outlet of the circulation pump 11. The flow transmitter 23 is arranged on the circulation pipeline 10, and is located away from the pressure transmitter 22. On one side of the pump 11, the flow transmitter 23 is a sensor that converts flow into an electric signal. It can monitor the flow of oil at the outlet of the circulating pump 11, thereby monitoring the pressure and flow at the outlet of the circulating pump 11, so as to facilitate adjusting the speed of the motor in the circulating pump 11 according to the pressure and flow at the outlet of the circulating pump 11, thereby forming a closed-loop control, so that the oil can flow under constant pressure and flow, ensuring the normal operation of the speed box 30, improving the reliability of the speed box 30, and extending the service life of the speed box 30, which is conducive to ensuring the continuous and reliable operation of the speed box 30 and saving energy and reducing emissions.

[0024] The rectifier and voltage regulating assembly 20 also includes a host computer 24, which is a computer. The host computer 24 is connected to the frequency converter 21, the pressure transmitter 22 and the flow transmitter 23. The pressure transmitter 22 converts the pressure signal at the outlet of the circulation pump 11 into an electric signal and transmits it to the host computer 24. The flow transmitter 23 converts the flow signal at the outlet of the circulation pump 11 into an electric signal and transmits it to the host computer 24. The host computer 24 adjusts the speed of the motor in the circulation pump 11 through the frequency converter 21 according to the pressure signal and the flow signal, thereby adjusting the pressure and flow of the oil pumped by the circulation pump 11. The host computer 24 uses variable frequency PID regulation to enable the oil at the outlet of the circulation pump 11 to flow under constant pressure and flow, thereby ensuring the normal operation of the speed booster 30 and improving the reliability of the speed booster 30.

[0025] The gearbox oil circulation structure provided by the utility model also includes a first ball valve 40 and a second ball valve 50.

The first ball valve 40 and the second ball valve 50 can control the opening or closing of the circulation pipeline 10, thereby improving the reliability of the structure.

[0026] The transmission box oil circulation structure provided by the utility model also includes a filter 60, which is arranged on the circulation pipeline 10. The filter 60 is located between the first ball valve 40 and the circulation pump 11. The filter 60 can filter the oil circulating into the circulation pump 11, thereby preventing impurities in the oil from entering the circulation pump 11 and affecting the operation of the circulation pump 11. At the same time, the oil is kept clean to ensure the normal operation of the transmission box 30.

[0027] The transmission box oil circulation structure provided by the utility model also includes a one-way valve 70, which is arranged on the circulation pipeline 10. The one-way valve 70 is located between the second ball valve 50 and the transmission box 30. The one-way valve 70 can limit the flow direction of the oil in the circulation pipeline 10 to prevent the oil from being sucked back, etc., thereby improving the structural reliability of the transmission box oil circulation structure provided by the utility model, further ensuring the normal operation of the transmission box, further improving the reliability of the transmission box, and further extending the service life of the transmission box.

[0028] The gearbox oil circulation structure provided by the utility model also includes a buffer tank 80, which is arranged on the circulation pipeline 10, and the buffer tank 80 is located between the first ball valve 40 and the gearbox 30. The buffer tank 80 can buffer the oil flowing out of the gearbox 30, and buffer the oil in the buffer tank 80. When the first ball valve 40 is opened, the circulation pump 11 pumps the oil from the buffer tank 80 to the gearbox 30 to complete the circulation of the oil, and the buffer tank 80 can smooth the flow process of the oil in the circulation pipeline 10, which is convenient for the rectifier and pressure regulating component 20 to control the oil, and avoid the problem that the oil directly circulates in the circulation pipeline 10 and causes the pressure and flow to be difficult to control.

[0029] The gearbox oil circulation structure provided by the utility model also includes a heat exchanger 90, which is arranged on the circulation pipeline 10. The heat exchanger 90 is located between the buffer tank 80 and the gearbox 30. The heat exchanger 90 can cool the oil by exchanging heat with the air, so as to prevent the oil flowing out of the gearbox 30 from expanding due to heat, and to prevent the expansion of the oil from affecting the pressure and flow of the oil itself, thereby facilitating the rectifier and pressure regulating component 20 to control the oil, ensuring that the oil can flow within the rated range of pressure and flow, ensuring the normal operation of the gearbox 30, improving the reliability of the gearbox 30, and extending the service life of the gearbox.

[0030] When the oil circulation structure of the gearbox provided by the utility model completes the oil circulation supply process, the first ball valve 40 and the second ball valve 50 are opened, the circulation pump 11 is started, and the oil passes through the pressure transmitter 22 and the flow transmitter 23 in turn. The pressure transmitter 22 and the flow transmitter 23 collect the pressure and flow of the oil and transmit them to the host computer 24. The host computer 24 adjusts the speed of the motor in the circulation pump 11 through the frequency converter 21 according to the pressure and flow at this time, thereby adjusting the pressure and flow of the oil pumped by the circulation pump 11, so that the circulation pump 11 can continuously pump the oil with the pressure and flow within the rated range, thereby improving the reliability of the structure. The oil enters the gearbox 30 through the second ball valve 50 and the one-way valve 70, ensuring the normal operation of the gearbox 30. The oil leaves the gearbox 30 and enters the cache tank 80 after heat exchange and cooling in the heat exchanger 90. The circulation pump 11 pumps the oil from the cache tank 80 to the gearbox 30 again, thereby completing the oil circulation process.
