Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of multi-functional aluminum electrolysis units, specifically a support bushing for a tool rotary reducer. Background Technology
[0002] The aluminum electrolysis multi-functional unit mainly consists of a main trolley, a tool trolley, and an aluminum tapping trolley. The tool trolley is the core of the aluminum electrolysis multi-functional unit. The tool mechanism that performs various operations on the aluminum electrolysis cell is installed on the crossbeam frame of the tool trolley through a tool rotation device. The tool rotation device is the core component that enables the various tools on the tool trolley to achieve rotational functions and allow for all-round operation.
[0003] However, in the operation of some existing rotary reducers, the output shaft is subjected not only to torque force but also to the squeezing force of the rotating gear disc of the mechanism. Furthermore, there is no support point between the rotary reducer and the gear at the shaft extension end. Long-term exposure to the squeezing force of the rotating gear disc of the mechanism can lead to the breakage of the reducer shaft, which in turn affects the normal use of the device and increases material consumption costs. Utility Model Content
[0004] The purpose of this utility model is to provide a support bushing for a tool rotary reducer to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a support bushing for a tool rotary reducer, comprising a base and a mounting shell fixedly connected to its surface, and further comprising:
[0006] A servo motor is mounted on one side of the base. The output shaft of the servo motor is fixedly connected to a first gear, and a second gear meshes with one side of the first gear.
[0007] An oil tank is installed on the inner wall of the base. The output shaft of the servo motor is provided with a protection mechanism to protect the output shaft. The surface of the oil tank is provided with a conveying mechanism to lubricate and clean the protection mechanism and the output shaft of the servo motor.
[0008] Preferably, the protection mechanism includes a bearing disposed on the output shaft of the servo motor, a support sleeve is fixedly connected to the surface of the bearing, and a connecting shell is rotatably connected to the output shaft of the servo motor.
[0009] Preferably, the conveying mechanism includes an oil pump disposed on the surface of the oil tank, the surface of the oil pump being connected to an oil outlet pipe, and the surface of the oil tank being connected to a return pipe.
[0010] Preferably, one end of the oil inlet pipe of the oil pump is connected to a filter housing, and the filter housing is used in conjunction with the oil pump.
[0011] Preferably, a valve is connected to one side of the oil tank.
[0012] Preferably, both the support sleeve and the bearing are located within the inner cavity of the connecting shell.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This invention, through the design of a protective mechanism, transfers the force originally acting between the first and second gears on the output shaft surface of the servo motor to itself. In this way, the output shaft of the servo motor only needs to bear the torque force, without having to bear the additional force generated by the contact between the teeth, thereby reducing wear on the output shaft, extending its service life, and ensuring the servo motor can operate smoothly and efficiently. Under the action of the conveying mechanism and oil tank, both the protective mechanism and the output shaft of the servo motor can be lubricated, significantly reducing wear between them. Furthermore, under the pressure of the lubricating oil, metal shavings, dust, and other impurities generated inside the protective mechanism can be cleaned, further reducing the frictional resistance of the protective mechanism and reducing wear. This solves the problems of easy breakage and wear of the output shaft in existing devices. Attached Figure Description

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0021] Please see Figure 1-4As shown, a support bushing for a tool rotary reducer includes a base 1. A mounting shell 2 is fixedly connected to the surface of the base 1. A servo motor 3 is mounted on one side of the base 1. The output shaft of the servo motor 3 is rotatably connected to the inner wall of the mounting shell 2. A first gear 4 is fixedly connected to the output shaft of the servo motor 3. A second gear 5 meshes with one side of the first gear 4. The diameter of the second gear 5 is larger than that of the first gear 4. The inner wall of the second gear 5 is rotatably connected to the inner wall of the mounting shell 2. Several connecting rods are fixedly connected to the surface of the second gear 5 for easy connection to other mechanical parts. Under this action, turning on the servo motor 3 can cause the first gear 4 to drive the second gear 5 meshing on its side to rotate. Since the diameter of the second gear 5 is larger than that of the first gear 4, the high-speed rotation of the servo motor 3 can be converted into a low-speed, high-torque output to meet the working requirements of tool rotation and achieve the effect of speed reduction and torque increase. An oil tank 6 is provided on the inner wall of the base 1 for storing lubricating oil. A conveying mechanism 7 is provided on the surface of the oil tank 6. A protection mechanism 8 is provided on the surface of the output shaft of the servo motor 3. The conveying mechanism 7 and the protection mechanism 8 work together. Under the action of the protective mechanism 8, the force point between the first gear 4 and the second gear 5 on the output shaft surface of the servo motor 3 can be transferred to itself, so that the output shaft of the servo motor 3 is only subjected to torque force and not to other additional forces generated by the contact between the teeth. This achieves stable and efficient operation of the servo motor 3, improves the equipment operating rate, reduces material consumption costs, and extends the service life of the servo motor 3. Under the action of the conveying mechanism 7, the lubricating oil in the inner cavity of the oil tank 6 can be extracted and conveyed to the inner cavity of the protective mechanism 8 to lubricate the protective mechanism 8 and clean the impurities in its inner cavity. Subsequently, the lubricating oil and the cleaned impurities will flow back to the inner cavity of the oil tank 6, be filtered and recycled, thereby effectively reducing the frictional resistance of the protective mechanism 8, further reducing the occurrence of wear, extending the service life of the protective mechanism 8, and keeping the protective mechanism 8 in good working condition to maintain its performance stability. A valve 10 is connected to one side of the oil tank 6. Under this action, when it is necessary to change the lubricating oil or clean the impurities in the inner cavity of the oil tank 6, the valve 10 can be opened to discharge them for subsequent use.
[0022] The protection mechanism 8 includes a bearing 83 mounted on the output shaft of the servo motor 3. A support sleeve 82 is fixedly connected to the surface of the bearing 83. There are two bearings 83 and two support sleeves 82. The output shaft of the servo motor 3 is rotatably connected to a connecting shell 81. The support sleeve 82 and the bearing 83 are both located in the inner cavity of the connecting shell 81. With the cooperation of the support sleeve 82 and the bearing 83, the force point between the first gear 4 and the second gear 5 on the surface of the output shaft of the servo motor 3 can be transferred to itself. This allows the output shaft of the servo motor 3 to be subjected only to torque force and not to other additional forces generated by the contact between the teeth. This greatly reduces the wear of the output shaft, extends the service life of the output shaft, and realizes the smooth and efficient operation of the servo motor 3.
[0023] The conveying mechanism 7 includes an oil pump 71 mounted on the surface of the oil tank 6. The oil pump 71's inlet pipe extends into the inner cavity of the oil tank 6. An oil outlet pipe 72 is connected to the surface of the oil pump 71, with one end of the outlet pipe 72 connected to one side of the connecting housing 81. A return oil pipe 73 is connected to the surface of the oil tank 6, with one end of the return oil pipe 73 connected to the other side of the connecting housing 81. Under this action, turning on the oil pump 71 can deliver the lubricating oil from the inner cavity of the oil tank 6 to the inner cavity of the connecting housing 81 through the oil outlet pipe 72, thereby lubricating the bearing 83 and the output shaft of the servo motor 3. Furthermore, under the pressure of the lubricating oil, the oil inside the connecting housing 81 can be conveyed... Metal shavings, dust, and other impurities generated in the oil tank flow through the return oil pipe 73 to the inner cavity of the oil tank 6, thereby effectively reducing the frictional resistance between the bearing 83 and the output shaft of the servo motor 3, further reducing wear, and reducing the accumulation of impurities in the inner cavity of the connecting housing 81, maintaining its internal cleanliness. One end of the oil inlet pipe of the oil pump 71 is connected to the filter housing 9, which works in conjunction with the oil pump 71. The filter housing 9 can effectively filter the impurities brought back to the inner cavity of the oil tank 6 by the return oil pipe 73, so that the lubricating oil re-entering the outlet oil pipe 72 can maintain a high purity and maintain good lubrication performance.
[0024] Working principle: When the servo motor 3 is turned on, it drives the first gear 4 and the second gear 5 meshing on one side to rotate. During gear transmission, an additional force is generated between the first gear 4 and the second gear 5 due to tooth-to-tooth contact. The support sleeve 82 can transfer the force point between the first gear 4 and the second gear 5 on the output shaft surface of the servo motor 3 to itself, so that the output shaft of the servo motor 3 only bears the torque force and is not subjected to other additional forces generated by tooth-to-tooth contact. This reduces the wear of the output shaft, extends the service life of the output shaft, and achieves stable and efficient operation of the servo motor 3. When the oil pump 71 is turned on, the lubricating oil in the inner cavity of the oil tank 6 can be pumped out through the oil outlet. Pipe 72 delivers lubricant to the inner cavity of the connecting shell 81, thereby lubricating the output shaft of the bearing 83 and the servo motor 3. This effectively reduces the frictional resistance between the bearing 83 and the output shaft of the servo motor 3, reducing wear. Under the pressure of the lubricating oil, metal shavings, dust, and other impurities generated inside the connecting shell 81 can flow with the lubricating oil through the return oil pipe 73 to the inner cavity of the oil tank 6, thus realizing the return of impurities and lubricating oil. Furthermore, the impurities brought back to the inner cavity of the oil tank 6 by the return oil pipe 73 are filtered by the filter shell 9, ensuring that the lubricating oil re-entering the outlet oil pipe 72 maintains a high purity, thereby maintaining good lubrication performance and realizing the recycling of lubricating oil.
[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
