Description

Technical Field

[0001] This utility model belongs to the technical field of gearbox parts, and in particular relates to a gearbox anti-slip double flat output shaft structure. Background Technology

[0002] In the field of mechanical transmission, the gearbox output shaft is a key component. Its main function is to transfer the kinetic energy of the transmission mechanism within the gearbox to external actuators, thereby driving the operation of mechanical equipment. Its performance directly affects the working efficiency and stability of the entire mechanical system.

[0003] Existing gearbox output shafts employ a circular design, relying primarily on key connections or interference fits for power transmission when connecting to mounting brackets and gears. However, existing gearbox output shafts suffer from the following drawbacks in practical use:

[0004] First, the existing gearbox output shaft has a relatively smooth circular shaft surface. When transmitting large torques, slippage can easily occur between the mounting bracket and gear and the shaft, resulting in unstable power transmission and reducing the transmission efficiency of the gearbox.

[0005] Secondly, the existing gearbox output shaft cannot lubricate the transmission mechanism inside the gearbox (the transmission mechanism inside the gearbox needs good lubrication during long-term operation to reduce wear and energy consumption).

[0006] In addition, the existing gearbox output shaft does not have the function of detecting the condition of the shaft itself, and cannot monitor the rotational speed of the shaft in real time. At the same time, when the shaft deforms due to long-term use, it is difficult to detect it in time, which may lead to more serious mechanical failures and affect the normal operation of the equipment.

[0007] Therefore, it is essential to invent a dual-flat output shaft structure for preventing slippage in a gearbox. Utility Model Content

[0008] To address the above problems, this utility model proposes a dual-flat output shaft structure for preventing slippage in a gearbox. The technical solution used is as follows:

[0009] A dual-flat output shaft structure for preventing slippage in a gearbox includes a shaft body, a first flat section, a mounting bracket, a second flat section, an oil injection mechanism, an oil delivery chamber, a sealing plug, and a status detection mechanism. The first flat section is located on the outer surface of one end of the shaft body, and the mounting bracket is fixed to the first flat section by an interference fit. The second flat section is located on the outer surface of the other end of the shaft body, and the oil injection mechanism is mounted on the outer surface of the shaft body. The input end of the oil injection mechanism is connected to an external oil storage mechanism, and the output end of the oil injection mechanism communicates with the interior of the oil delivery chamber. The oil delivery chamber is located inside the shaft body, and several output ends of the oil delivery chamber are arranged in a straight line array on the outer surface of the shaft body. Each output end of the oil delivery chamber is sealed with a sealing plug. The status detection mechanism is fixed on the shaft body.

[0010] Furthermore, the first and second flat positions on the shaft are both covered and fixed with reinforcing shells made of tungsten carbide alloy. This arrangement can improve the high temperature resistance and wear resistance of the shaft.

[0011] Furthermore, the oil injection mechanism includes an annular shell, a temporary storage cavity, and an oil delivery pipe. The annular shell is rotatably mounted on the outer side of the shaft using a sealed bearing, and a temporary storage cavity is provided between the annular shell and the shaft, which communicates with the inside of the oil delivery cavity. An oil delivery pipe is fixed to the outer side of the annular shell through a joint, and the oil delivery pipe is connected to an external oil storage mechanism. The annular shell is fixed to the gearbox housing by bolts. This configuration allows lubricating oil to be delivered to the oil delivery cavity without stopping the shaft.

[0012] Furthermore, the status detection mechanism includes a miniature power supply, an electromagnet, wires, and a detection housing. The miniature power supply is fixed to one end of the shaft with bolts, and the electromagnet is fixed to the other end of the shaft with bolts. The electromagnet is electrically connected to the miniature power supply via wires. The wires are fixed inside the shaft and are tensioned. A detection housing is provided outside the electromagnet, with a gap between the detection housing and the electromagnet. A Hall element is fixed to the inner wall of the detection housing with bolts, and the Hall element is electrically connected to the gearbox controller via a data cable. The detection housing is fixed to the gearbox housing with bolts. This configuration allows for the detection of the shaft's rotation speed when it rotates normally, and facilitates timely detection by staff when the shaft deforms due to prolonged use.

[0013] Furthermore, the conductor is made of copper-nickel alloy material, and the nickel content inside the conductor is 40%. With this configuration, the copper-nickel alloy material can meet the power supply requirements of the micro power supply to the electromagnet. However, when the shaft deforms, the copper-nickel alloy with a nickel content of 40% cannot adapt through its own elastic deformation. Instead, it will reach its bearing limit under a certain deformation, thus breaking and disconnecting the power supply to the electromagnet.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention, when in use, can connect to the transmission mechanism inside the gearbox via gears at the second flat position, and fix the mounting bracket to the external actuator via bolts, thereby transmitting the kinetic energy of the gearbox transmission mechanism to the external actuator. The first and second flat positions prevent the mounting bracket and gears from sliding with the shaft, thereby improving the transmission stability of the gearbox output shaft.

[0016] 2. The combination of the oil injection mechanism and the oil delivery chamber of this utility model allows for the removal of the corresponding sealing plug during use. The lubricating oil is then delivered into the oil delivery chamber via the oil injection mechanism. At this point, the lubricating oil can be discharged into the gearbox from the removed sealing plug location, thereby lubricating the transmission mechanism inside the gearbox. Since the annular shell and shaft are rotatably connected, the gearbox does not need to be stopped when lubricating oil is injected into the oil delivery chamber.

[0017] 3. The state detection mechanism of this utility model allows the electromagnet to rotate correspondingly inside the detection housing when the shaft rotates, and the Hall element to generate a corresponding Hall voltage. The gearbox controller can determine the rotational speed of the shaft by detecting the change in Hall voltage, thus facilitating the operator to detect the rotational speed of the gearbox output shaft. In addition, when the shaft deforms due to prolonged use, the shaft will squeeze the wires, causing the micro power supply to fail to supply power to the electromagnet, and thus the Hall element will fail to send a signal to the gearbox controller. The operator can thus determine whether the shaft is damaged. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Please see Figures 1 to 3 As shown, this utility model is a dual-flat output shaft structure for preventing slippage in a gearbox, including a shaft body 1, a first flat position 2, a mounting bracket 3, a second flat position 4, an oil injection mechanism 5, an oil delivery chamber 6, a sealing plug 7, and a status detection mechanism 8. The first flat position 2 is formed on the outer side of one end of the shaft body 1, and the mounting bracket 3 is fixed to the first flat position 2 of the shaft body 1 by an interference fit. The second flat position 4 is formed on the outer side of the other end of the shaft body 1, and the oil injection mechanism 5 is mounted on the outer side of the shaft body 1. The input end of the oil injection mechanism 5 is connected to an external oil storage mechanism, and the output end of the oil injection mechanism 5 communicates with the inside of the oil delivery chamber 6. The oil delivery chamber 6 is located inside the shaft body 1, and several output ends of the oil delivery chamber 6 are arranged in a straight line array on the outer side of the shaft body 1. Each output end of the oil delivery chamber 6 is sealed with a sealing plug 7. The status detection mechanism 8 is fixed on the shaft body 1.

[0027] Specifically, the first flat position 2 and the second flat position 4 on the shaft 1 are both wrapped and fixed with a reinforcing shell. The reinforcing shell is made of tungsten carbide alloy. When in use, the tungsten carbide alloy shell has high temperature resistance and wear resistance, thereby enhancing the protective effect of the shaft 1 and extending the service life of the shaft 1.

[0028] Specifically, the oil injection mechanism 5 includes an annular shell 51, a temporary storage cavity 52, and an oil supply pipe 53. The annular shell 51 is rotatably mounted on the outer side of the shaft 1 using a sealed bearing, and a temporary storage cavity 52 is provided between the annular shell 51 and the shaft 1. The temporary storage cavity 52 communicates with the inside of the oil supply cavity 6. The oil supply pipe 53 is fixed to the outer side of the annular shell 51 through a joint, and the oil supply pipe 53 is connected to an external oil storage mechanism. The annular shell 51 is fixed to the gearbox housing by bolts. During use, the operator can deliver lubricating oil into the temporary storage cavity 52 through the cooperation of the oil supply pipe 6 and the external oil storage mechanism. As the amount of lubricating oil gradually increases, the lubricating oil will gradually enter the inside of the oil supply cavity 6. Furthermore, since the annular shell 51 and the shaft 1 are sealed and rotatably connected, it is not necessary to stop the operation of the gearbox when lubricating oil is introduced into the oil supply cavity 6.

[0029] Specifically, the status detection mechanism 8 includes a miniature power supply 81, an electromagnet 82, a wire 83, and a detection housing 84. The miniature power supply 81 is fixed to one end of the shaft 1 by bolts, and the electromagnet 82 is fixed to the other end of the shaft 1 by bolts. The electromagnet 82 is electrically connected to the miniature power supply 81 via the wire 83. The wire 83 is fixed inside the shaft 1 and is tensioned. The detection housing 84 is provided on the outside of the electromagnet 82, with a gap between the detection housing 84 and the electromagnet 82. A Hall element is fixed to the inner wall of the detection housing 84 by bolts. The Hall element is electrically connected to the gearbox controller via a data cable. The shaft 1 is fixed to the gearbox housing with bolts. When the shaft 1 rotates, the electromagnet 82 rotates accordingly inside the detection housing 84, and the Hall element generates a corresponding Hall voltage. The gearbox controller can determine the rotational speed of the shaft 1 by detecting the change in Hall voltage, so that the operator can detect the rotational speed of the gearbox output shaft. In addition, when the shaft 1 deforms due to long-term use, the shaft 1 will squeeze the wire 83, causing the micro power supply 81 to be unable to supply power to the electromagnet 82. As a result, the Hall element cannot send a signal to the gearbox controller, so the operator can determine whether the shaft 1 is damaged.

[0030] Specifically, the wire 83 is made of copper-nickel alloy material, and the nickel content inside the wire 83 is 40%. With this setting, the wire made of copper-nickel alloy material can meet the power supply requirements of the micro power supply 81 to the electromagnet. However, when the shaft 1 deforms, the copper-nickel alloy with a nickel content of 40% cannot adapt through its own elastic deformation. Instead, it will reach its limit under a certain deformation and break, thereby disconnecting the power supply to the electromagnet 82.

[0031] Please see Figure 1-3 As shown, this utility model is a dual-flat output shaft structure for preventing slippage in a gearbox. Its working principle is as follows: When in use, it is first connected to the transmission mechanism inside the gearbox through gears at the second flat position 4. Then, the mounting bracket 3 is fixed to the external actuator, thereby transmitting the kinetic energy of the gearbox transmission mechanism to the external actuator. The operator can lubricate the transmission mechanism inside the gearbox through the cooperation of the oil injection mechanism 5 and the oil supply chamber 6. In addition, the status detection mechanism 8 can detect the rotation speed and whether deformation occurs in the shaft 1, and transmit the detected data to the gearbox controller.
