[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In the present invention, with the cooperation of the dynamic adaptive contact adjustment component, when the transmission rotor shaft wears and deviates, the microprocessor controller that detects the feedback data controls the bidirectional rotor motor and the electromagnetic blocker for pre-driving through electromagnetic signals, so as to facilitate the adjustment of the contact member. Then, the electromagnetic blocker controls through electromagnetic signals to release the synchronous transmission gear, and uses the connecting sleeve to form a connection with the synchronous transmission gear through the meshing connection of the tooth thread and the inner tooth ring of the tooth. When the transmission rotor shaft rotates, the connecting sleeve rotates synchronously, thereby driving the synchronous transmission gear to rotate, and through the meshing connection of the synchronous transmission gear and the synchronous drive gear, the synchronous drive gear rotates synchronously. Furthermore, the synchronous rotating shaft rotates and adjusts at the center side of the synchronous drive gear. Thus, under the action of the synchronous rotating shaft, the small transmission gear adjusts inside the installation plate frame and meshes with the adjustment gear at one end. Then, through the meshing connection of the symmetric adjustment gears at both ends, the connecting force-bearing arm frame and the contact member are driven to form an angle adjustment, so that the contact member contacts the circumferential surface of the transmission rotor shaft. After that, the bidirectional rotor motor starts, and according to the feedback of the vibration sensor and the current sensor, the angle fine-motion contact frame and the shape memory alloy contact member are driven to form contact adjustment on the side of the transmission rotor shaft. At the same time, the bidirectional rotor motor slides through the magnetic connection block and the magnetic chute rail, so that the positions of the angle fine-motion contact frame and the shape memory alloy contact member can better adjust the contact pressure and position with the transmission rotor shaft, and then automatically adjust the contact state according to the working conditions, improving the operation adaptability and reliability of the transmission rotor shaft. Moreover, the setting of the shape memory alloy contact member enables the above-mentioned structure in contact with the transmission rotor shaft to automatically adjust according to environmental changes such as temperature and pressure.

[0023] 2. In the present invention, with the cooperation of the rotor shaft protection component, the photoelectric sensor in the detection sensor seat is connected to monitor the operating state of the transmission rotor shaft in real time. The monitoring data is transmitted to the microprocessing controller through wireless communication, enabling the microprocessing controller to analyze the current working conditions based on the monitoring data, determine whether it is necessary to adjust the contact state and magnetic field intensity. Then, when adjustment is required, the microprocessing controller controls the start of the bidirectional control brushless motor through an electromagnetic signal. By using the bidirectional control brushless motor to drive the transmission of the synchronous output shaft rod and the driving small rotating gear, the power is transmitted to the insulating rotating gear, causing the insulating rotating gear to drive the working arc plate to rotate on the outer circumferential side of the sleeve. Synchronously, when the working arc plate rotates, under the cooperation of the magnetic field controller and multiple groups of electromagnets, the magnetic field intensity and parameters are dynamically adjusted to control the rotation of the magnetic particles. And the magnetic particles injected through the inlet and outlet core ends rotate on the surface of the transmission rotor shaft under the action of the magnetic field, forming a uniform lubricating layer to reduce friction and wear, realizing the adjustment of the contact state of the transmission rotor shaft. And after the operation is completed, the injected magnetic particles can be discharged and replaced through the inlet and outlet core ends, reducing the friction and wear between the transmission rotor shaft and the contact components in the above overall operation, and extending the service life of the transmission rotor shaft.

The ball bearing member 101 and the connecting sleeve 102 are sleeved and installed on the outer circumference of the transmission rotor shaft 6. Tooth threads 1094 are provided on the outer surface of the side end of the connecting sleeve 102. Tooth inner rings 103 are provided on the surface of the inner slot at the center end of the synchronous rotating gear 104. The connecting sleeve 102 is connected to the synchronous rotating gear 104 through the meshing connection of the tooth threads 1094 and the tooth inner rings 103. The synchronous driving gear 105 and the synchronous rotating gear 104 are meshed and connected, and a synchronous rotating shaft 106 is connected to the center end of the synchronous driving gear 105.

[0041] A small rotating gear 107 is connected to the side end of the synchronous rotating shaft 106. An installation plate frame 108 is firmly connected to the side end of the small rotating gear 107. The installation plate frame 108 is installed inside the detection and adjustment noise reduction housing 4. Adjusting gears 109 are symmetrically installed at the left and right ends of the installation plate frame 108. An electromagnetic blocker 1093 is installed on the side of the synchronous rotating gear 104.

[0042] A connecting force-bearing arm frame 1090 is installed on the outer circumference of the adjusting gear 109. A contact member 1091 is rotatably connected to the bottom end of the connecting force-bearing arm frame 1090. A magnetic sliding groove track 1095 is provided on the side surface of the contact member 1091. A magnetic connecting block 1096 is slidably connected inside the magnetic sliding groove track 1095. A two-way rotor motor 1097 is connected to the side end of the magnetic connecting block 1096. A bearing rotor structure 1092 is provided on the side end of the electromagnetic blocker 1093.

[0043] Angle fine-motion contact frames 1098 are symmetrically hinged to the left and right ends of the two-way rotor motor 1097. The two-way rotor motor 1097 and the electromagnetic blocker 1093 are connected to vibration sensors and current sensors installed on the surface of the contact member 1091 through electromagnetic signals. Both the vibration sensors and the current sensors are signal-connected to the micro-processing controller in the motor 1. A shape memory alloy contact member 1099 is installed on the side of the angle fine-motion contact frame 1098.

[0044] In a specific solution, when the motor 1 starts and the output shaft begins to rotate, and power is transmitted through the transmission rotor shaft 6, vibration sensors and current sensors installed on the surface of the contact member 1091 inside the detection and adjustment noise reduction housing 4 monitor the operating state of the transmission rotor shaft 6 in real time. The monitoring data is transmitted to the microprocessing controller through wireless communication. The microprocessing controller analyzes and judges the current working condition based on the monitoring feedback data of the transmission rotor shaft 6, determines the requirements, and actively adjusts the contact state. Then, when the transmission rotor shaft 6 is worn and offset, the microprocessing controller that detects the feedback data controls the two-way rotor motor 1097 and the electromagnetic blocker 1093 through electromagnetic signals for pre-driving, so as to realize the adjustment of the contact member 1091. After that, the electromagnetic blocker 1093 is controlled through electromagnetic signals to release the synchronous rotating gear 104, and the connecting sleeve 102 is connected to the synchronous rotating gear 104 through the meshing connection of the tooth thread 1094 and the inner tooth ring 103. When the transmission rotor shaft 6 rotates, the connecting sleeve 102 rotates synchronously, thereby driving the synchronous rotating gear 104 to rotate. Through the meshing connection of the synchronous rotating gear 104 and the synchronous driving gear 105, the synchronous driving gear 105 rotates synchronously, and then the synchronous rotating shaft 106 rotates and adjusts at the center edge side of the synchronous driving gear 105. Under the action of the synchronous rotating shaft 106, the small rotating gear 107 adjusts inside the mounting plate frame 108 and meshes with the adjusting gear 109 at one end. Then, through the meshing connection of the symmetrically arranged adjusting gears 109 at both ends, the connecting force-bearing arm frame 1090 and the contact member 1091 are driven to form an angular adjustment, so that the contact member 1091 contacts the circumferential surface of the transmission rotor shaft 6. After that, the two-way rotor motor 1097 starts, and according to the feedback of the vibration sensor and the current sensor, it drives the angular micro-motion contact frame 1098 and the shape memory alloy contact member 1099 to form contact adjustment on the side of the transmission rotor shaft 6. At the same time, the two-way rotor motor 1097 is slidably connected through the magnetic connection block 1096 and the magnetic chute rail 1095, so that the positions of the angular micro-motion contact frame 1098 and the shape memory alloy contact member 1099 can better adjust the contact pressure and position with the transmission rotor shaft 6, and then automatically adjust the contact state according to the working condition, improving the operation adaptability and reliability of the transmission rotor shaft 6. The setting of the shape memory alloy contact member 1099 enables the structure in contact with the transmission rotor shaft 6 to automatically adjust according to environmental changes such as temperature and pressure.

[0045] In the present invention, according to Figure 3 、 Figure 4 、 Figure 8 and Figure 9 shown, the rotor shaft protection assembly 11 includes:

[0046] Insulating rotating gear 110, bidirectional control brushless motor 111, synchronous output shaft 112 and driving small rotating gear 113. The bidirectional control brushless motor 111 is fixedly connected to the inner wall surface of the installation connection housing 5 through a hoop. The bidirectional control brushless motor 111 is connected through the synchronous output shaft 112 and the driving small rotating gear 113 connected to the left and right ends. The driving small rotating gear 113 and the insulating rotating gear 110 are meshed and connected.

[0047] Both the insulating rotating gear 110 and the driving small rotating gear 113 are provided in two groups. Four connecting detection sensor seats 118 are fixedly connected around the side surface of the two groups of insulating rotating gears 110. Operating arc plates 115 are fixedly connected to the side ends of the four connecting detection sensor seats 118. A magnetic field controller 1190 is installed on the surface of the operating arc plate 115. A plurality of electromagnets 119 are installed on the periphery of the magnetic field controller 1190.

[0048] A sleeve 116 is installed inside the operating arc plate 115. The two ends of the sleeve 116 are connected to the inlet and outlet ends of the installation connection housing 5. An inlet and outlet core end 117 is installed on the bottom surface of the sleeve 116.

[0049] In a specific solution, when the above-mentioned motor 1 operates to drive the transmission rotor shaft 6 to rotate synchronously, the photoelectric sensor in the connection detection sensor seat 118 monitors the operating state of the transmission rotor shaft 6 in real time. The monitoring data is transmitted to the microprocessing controller through wireless communication, so that the microprocessing controller analyzes the current working conditions according to the monitoring data, judges whether it is necessary to adjust the contact state and magnetic field intensity. Then, when adjustment is required, the microprocessing controller controls the bidirectional control brushless motor 111 to start through an electromagnetic signal. Using the transmission of the bidirectional control brushless motor 111 through the synchronous output shaft 112 and the driving small rotating gear 113, the power is transmitted to the insulating rotating gear 110, so that the insulating rotating gear 110 drives the operating arc plate 115 to rotate on the outer circumference of the sleeve 116. Synchronously, when the operating arc plate 115 rotates, under the cooperation of the magnetic field controller 1190 and the plurality of electromagnets 119, the magnetic field intensity and parameters are dynamically adjusted to control the rotation of the magnetic particles. The magnetic particles injected through the inlet and outlet core end 117 rotate on the surface of the transmission rotor shaft 6 under the action of the magnetic field, forming a uniform lubricating layer, reducing friction and wear, and realizing the adjustment of the contact state of the transmission rotor shaft 6. And after the operation is over, the injected magnetic particles can be discharged and replaced through the inlet and outlet core end 117, so that the above overall operation reduces the friction and wear between the transmission rotor shaft 6 and the contact components, and extends the service life of the transmission rotor shaft 6.

[0050] In the present invention, according to Figure 1 - Figure 3 As shown, a motor, the motor 1 includes:

[0051] A heat dissipation and dust exhaust fan 8, a dust-proof net 7, a wire box 2 and a rotor structure 9. The heat dissipation and dust exhaust fan 8 is installed inside the side end of the motor 1. The dust-proof net 7 is installed on the left end frame of the motor 1. The wire box 2 is installed on the top of the motor 1.

[0052] The rotor structure 9 is installed inside the motor 1 and is connected to the transmission rotor shaft 6. The bottom end of the motor 1 is firmly connected with a buffer and noise reduction support seat 3.

[0053] In a specific solution, when the motor 1 starts, the heat dissipation and dust exhaust fan 8 starts. By rotating at high speed, it discharges the heat inside the motor 1, and at the same time discharges dust and impurities, keeping the inside of the motor 1 clean. And the dust-proof net 7 blocks the entry of external dust and impurities into the motor 1, protects the internal components, and extends the service life of the motor 1. The wire box 2 centrally manages the wires and cables of the motor 1, ensuring the safety and neatness of the lines, and facilitating maintenance and inspection. Among them, the rotor structure 9 converts the electrical energy of the motor 1 into mechanical energy through the connection with the transmission rotor shaft 6 to achieve power transmission. And the buffer and noise reduction support seat 3 reduces the vibration and noise during the operation of the motor 1 through buffer and shock absorption materials, improving the stability and reliability of the motor 1.

[0054] The wiring diagrams of the electromagnetic blocker 1093, the two-way rotor motor 1097, the two-way control brushless motor 111, the connection detection sensor seat 118, the magnetic field controller 1190, the vibration sensor, the current sensor and the photoelectric sensor in the present invention belong to the common knowledge in the art. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the electromagnetic blocker 1093, the two-way rotor motor 1097, the two-way control brushless motor 111, the connection detection sensor seat 118, the magnetic field controller 1190, the vibration sensor, the current sensor and the photoelectric sensor will not be explained in detail.

[0055] Working principle of the present invention: First, when the motor 1 starts, the rotor structure 9 converts the electrical energy of the motor 1 into mechanical energy through the connection with the transmission rotor shaft 6 to achieve the transmission of power, causing the output shaft to start rotating. When transmitting power through the transmission rotor shaft 6, vibration sensors and current sensors installed on the surface of the contact member 1091 inside the detection and adjustment noise reduction housing 4 monitor the operating state of the transmission rotor shaft 6 in real time. The monitoring data is transmitted to the microprocessing controller through wireless communication. The microprocessing controller analyzes and judges the current working condition based on the monitoring feedback data of the transmission rotor shaft 6, decides the requirements, and actively adjusts the contact state. Then, when the transmission rotor shaft 6 is worn and offset, the microprocessing controller that detects the feedback data controls the bidirectional rotor motor 1097 and the electromagnetic blocker 1093 through electromagnetic signals for pre-driving to facilitate the adjustment of the contact member 1091. After that, the electromagnetic blocker 1093 is controlled through electromagnetic signals to release the synchronous rotating gear 104, and the connecting sleeve 102 is connected to the synchronous rotating gear 104 through the meshing connection of the tooth thread 1094 and the inner tooth ring 103, so that when the transmission rotor shaft 6 rotates, the connecting sleeve 102 rotates synchronously, thereby driving the synchronous rotating gear 104 to rotate, and through the meshing connection of the synchronous rotating gear 104 and the synchronous driving gear 105, the synchronous driving gear 105 rotates synchronously, and then the synchronous rotating shaft 106 rotates and adjusts at the center edge side of the synchronous driving gear 105. Thus, under the action of the synchronous rotating shaft 106, the small rotating gear 107 adjusts inside the mounting plate frame 108 and meshes with the adjusting gear 109 at one end. Then, through the meshing connection of the symmetric adjusting gears 109 at both ends, the connecting force-bearing arm frame 1090 and the contact member 1091 are driven to form an angular adjustment, so that the contact member 1091 contacts the circumferential surface of the transmission rotor shaft 6. After that, the bidirectional rotor motor 1097 starts, and according to the feedback of the vibration sensor and the current sensor, it drives the angular micro-movement contact frame 1098 and the shape memory alloy contact member 1099 to form contact adjustment on the side of the transmission rotor shaft 6. At the same time, the bidirectional rotor motor 1097 slides through the magnetic connection block 1096 and the magnetic sliding track 1095, so that the positions of the angular micro-movement contact frame 1098 and the shape memory alloy contact member 1099 can better adjust the contact pressure and position with the transmission rotor shaft 6, and then automatically adjust the contact state according to the working condition, improving the operation adaptability and reliability of the transmission rotor shaft 6. The setting of the shape memory alloy contact member 1099 enables the above structures in contact with the transmission rotor shaft 6 to automatically adjust according to environmental changes such as temperature and pressure. At the same time, the photoelectric sensor in the connection detection sensor seat 118 monitors the operating state of the transmission rotor shaft 6 in real time, and the monitoring data is transmitted to the microprocessing controller through wireless communication, so that the microprocessing controller analyzes the current working condition based on the monitoring data and judges whether it is necessary to adjust the contact state and magnetic field strength. Then, when adjustment is required,The microprocessor controller controls the start of the bidirectional control brushless motor 111 through an electromagnetic signal. By using the bidirectional control brushless motor 111 to drive the small rotating gear 113 through the synchronous output shaft 112, the power is transmitted to the insulating rotating gear 110, so that the insulating rotating gear 110 drives the working arc plate 115 to rotate on the outer circumferential side of the sleeve 116. Synchronously, when the working arc plate 115 rotates, under the cooperation of the magnetic field controller 1190 and multiple groups of electromagnets 119, the magnetic field strength and parameters are dynamically adjusted to control the rotation of the magnetic particles. And the magnetic particles injected through the inlet and outlet core end 117 rotate on the surface of the transmission rotor shaft 6 under the action of the magnetic field, forming a uniform lubricating layer to reduce friction and wear, realizing the adjustment of the contact state of the transmission rotor shaft 6. And after the operation is completed, the injected magnetic particles can be discharged and replaced through the inlet and outlet core end 117, so that the overall operation reduces the friction and wear between the transmission rotor shaft 6 and the contact components, prolongs the service life of the transmission rotor shaft 6, and the heat dissipation and dust exhaust fan 8 starts to discharge the heat inside the motor 1 through high-speed rotation, and at the same time discharges dust and impurities to keep the inside of the motor 1 clean. And the dust-proof net 7 blocks the entry of external dust and impurities into the motor 1 to protect the internal components and prolong the service life of the motor 1.,
