[0001] The invention relates to the field of gear boxes, and in particular to a breathing valve device and a gear box that take temperature, noise and vibration monitoring into consideration. Background Art

[0002] In mechanical transmission, the gearbox is an indispensable and important component, which can change the speed and torque of the prime mover according to actual needs. During the working process of the gearbox, as the working time increases, various faults will inevitably occur in the gearbox, causing the transmission chain to not work properly.

[0003] Therefore, some gearboxes are equipped with vibration sensors to detect the vibration frequency of the gearbox. Through analysis, it can be concluded whether the gearbox is faulty. For gearboxes that are already in operation, if vibration sensors are to be installed, additional holes need to be drilled in the box body, which reduces the strength of the box body and increases the difficulty of installation, especially in some compact working conditions where vibration sensors cannot be installed.

[0032] like Figure 1 As shown, this embodiment provides a breathing valve device that takes into account both temperature noise and vibration monitoring, which can be used for vibration detection of a gearbox. The breathing valve device that takes into account both temperature noise and vibration monitoring includes a pressure relief component 1 and a monitoring component 2. The pressure relief component 1 includes a breathing valve seat 11, a one-way valve core 12 and an elastic member 13. The breathing valve seat 11 is configured to be connected to the housing of the gearbox. The breathing valve seat 11 includes an intake channel 111 and an exhaust channel 112. The intake channel 111 is configured to communicate with the inner cavity of the gearbox. The one-way valve core 12 is arranged in the breathing valve seat 11. The elastic member 13 is in a compressed state. The one-way valve core 12 can block the intake channel 111 under the elastic force of the elastic member 13 to isolate the intake channel 111 and the exhaust channel 112. The monitoring component 2 includes a circuit board 21 and a vibration sensor. The circuit board 21 is mounted on the breathing valve seat 11. The vibration sensor is arranged on the circuit board 21 for detecting the vibration parameters of the gearbox.

[0033] The breathing valve seat 11 is connected to the gearbox, and the air inlet channel 111 of the breathing valve seat 11 is connected to the inner cavity of the gearbox. When the gas pressure in the gearbox is too high, the air pressure pushes the one-way valve core 12 to overcome the elastic force of the elastic member 13, and the one-way valve core 12 is converted from the state of blocking the air inlet channel 111 to the state of opening the air inlet channel 111, so that the air inlet channel 111 is connected to the exhaust channel 112, and the excess gas in the gearbox is discharged through the exhaust channel 112, thereby reducing the air pressure in the gearbox and ensuring the safe operation of the gearbox. By installing the circuit board 21 on the breathing valve seat 11, the vibration sensor is integrated on the circuit board 21 to realize the vibration parameter detection of the gearbox. The entire breathing valve device that takes into account temperature noise and vibration monitoring has a compact structure, occupies a small space, is easy to install, and does not require additional drilling on the gearbox body, thereby avoiding reducing the structural strength of the gearbox body and reducing the modification cost of the gearbox.

[0034] Optionally, the breathing valve device taking into account both temperature noise and vibration monitoring also includes a housing 3, which is covered on the breathing valve seat 11, and the monitoring component 2 is located in the housing 3. By covering the breathing valve seat 11 with the housing 3, the monitoring component 2 is protected to prevent dust and other debris from damaging the monitoring component 2, providing a stable operating environment for the monitoring component 2, reducing the failure rate of the monitoring component 2, and improving the service life of the entire breathing valve device taking into account both temperature noise and vibration monitoring. The housing 3 can be threaded or clamped with the breathing valve seat 11 to facilitate disassembly and assembly.

[0035] Optionally, the monitoring component 2 further includes a power supply 22, which is spaced apart from the circuit board 21, and is used to supply power to the circuit board 21. Since the power supply 22 emits heat when supplying power, the power supply 22 is spaced apart from the circuit board 21, thereby reducing the adverse effect of the heat of the power supply 22 on the circuit board 21 and improving the heat dissipation effect of the power supply 22.

[0036] Optionally, an elastic gasket 23 is sandwiched between the power supply 22 and the housing 3. By providing the elastic gasket 23, the adverse effect of the gearbox vibration on the power supply of the power supply 22 is reduced, and the service life of the power supply 22 is increased. The elastic gasket 23 can be made of nylon spring gasket, which has good wear resistance and heat resistance.

[0037] Optionally, a spacer 24 is provided between the power supply 22 and the circuit board 21. By providing the spacer 24, the installation stability of the power supply 22 is ensured, and at the same time, the spacer 24 can avoid various electrical components on the surface of the circuit board 21 to ensure the heat dissipation efficiency of the circuit board 21.

[0038] Optionally, the circuit board 21 is threadedly connected to the breathing valve seat 11 through a fastener 25. The fastener 25 can be a screw, and the circuit board 21 and the breathing valve seat 11 can be detachably mounted by drilling a threaded hole on the breathing valve seat 11, passing the screw through the circuit board 21 and screwing it into the threaded hole of the breathing valve seat 11.

[0039] Optionally, one end of the elastic member 13 abuts against the circuit board 21, and the other end abuts against the one-way valve core 12. The elastic member 13 can be a spring, which is easy to obtain and has low cost. Corresponding guide columns can be provided on the circuit board 21 and the one-way valve core 12 to facilitate the installation of the spring.

[0040] To facilitate the detection of the temperature in the gearbox, the monitoring component 2 may optionally further include a temperature sensor, which is disposed on the circuit board 21 and is used to detect the temperature parameters of the gearbox. The circuit board 21 may use a wireless communication protocol (such as wifi, Bluetooth, ZigBee, etc.) to transmit the vibration parameters and temperature parameters of the gearbox to the host computer.

[0041] To facilitate the detection of the noise of the gearbox, the monitoring component 2 may also include a noise sensor, which is arranged on the circuit board 21 and is used to detect the noise parameters of the gearbox. The noise sensor is a sensor with a built-in capacitive electret microphone that is sensitive to sound. The electret surface is opposite to the back electrode, and there is a very small air gap in the middle, forming a flat plate capacitor with the air gap and the electret as insulating media, and the back electrode and the metal layer on the electret as two electrodes. The sound wave causes the electret film in the microphone to vibrate, resulting in a change in capacitance, and generates a small voltage that changes accordingly, thereby realizing the conversion of optical signals into electrical signals.

[0042] To facilitate the connection between the breathing valve seat 11 and the gear box, optionally, an external thread 113 is provided on the outer peripheral wall of the breathing valve seat 11, and the external thread 113 is located outside the air intake channel 111. The breathing valve seat 11 is threadedly connected to the gear box through the external thread 113.

[0043] The breathing valve device that takes into account both temperature noise and vibration monitoring provided in this embodiment is connected to the gear box through the breathing valve seat 11, and the air intake channel 111 of the breathing valve seat 11 is connected to the inner cavity of the gear box. When the gas pressure in the gear box is too large, the air pressure pushes the one-way valve core 12 to overcome the elastic force of the elastic member 13, and the one-way valve core 12 is converted from a blocked air intake channel 111 state to an open air intake channel 111 state, so that the air intake channel 111 is connected to the exhaust channel 112, and the excess gas in the gear box is discharged through the exhaust channel 112, thereby reducing the air pressure in the gear box and ensuring the safe operation of the gear box. By installing a circuit board 21 on the breathing valve seat 11 and integrating a vibration sensor on the circuit board 21, the vibration parameter detection of the gear box is realized. The structure is compact, occupies little space, and is easy to install. No additional holes need to be drilled on the gear box body, thereby avoiding reducing the structural strength of the gear box body and reducing the modification cost of the gear box.

[0044] This embodiment also provides a gearbox, including the above-mentioned breathing valve device that takes into account temperature, noise and vibration monitoring. It does not require additional holes to be opened on the box body, thereby avoiding reducing the structural strength of the box body. Under the premise of ensuring the structural strength of the box body, the installation of the sensor is achieved. It has a compact structure, occupies a small space, is easy to install, and reduces the modification cost of the gearbox.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
