The drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application belongs.

Therefore, the features defined as "first" and "second" can explicitly include at least one of the features. In the description of the present invention, "multiple" means at least two, such as two, three, etc.; "several" means at least one, such as one, two, three, etc., unless otherwise clearly and specifically defined.
[0036] In the present invention, unless otherwise clearly defined, the terms "install", "connect", "connect", "fix", "set", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0037] In the present utility model, unless otherwise clearly defined, a first feature being “on”, “above”, “above”, “below”, “below”, “below” or “below” a second feature may mean that the first feature is in direct contact with the second feature, or the first feature and the second feature are in indirect contact through an intermediate medium.

[0038] Research has found that the reducer and the housing of the base are generally sealed, and there is lubricating oil inside the reducer. All gears and bearings in the reducer are immersed in the lubricating oil to reduce friction and wear, help dissipate heat and cooling. The viscosity of the lubricating oil can help disperse and bear the load transmitted to the reducer, reduce impact and vibration, and protect the parts inside the reducer. Due to the good sealing between the reducer and the housing, the bearings in the base are not connected to the lubricating oil in the reducer, and the oil in the reducer cannot be immersed in the bearings in the base. The reason for the shortened life of the bearings in the base is the weakened lubrication effect. The moisture in the external environment entering the housing also has a certain effect on the corrosion of the bearings in the base. Although the bearings located inside the base housing are initially lubricated and protected by grease, the grease cannot be easily added and replaced regularly. The bearings in the base are prone to wear in a high temperature environment when they run for a long time.
[0039] In order to further improve the problems of wear and short service life of the bearings in the machine base, the present disclosure proposes the following technical solutions.
[0040] like Figures 1 to 3 As shown, the base of the driving mechanism provided by the embodiment of the present disclosure includes: a shell 100 and a bearing seat 150; the shell 100 defines an internal space 110, the bearing seat 150 is used to support the bearing 120 in the driving mechanism, and the bearing seat 150 and the bearing 120 are both located in the internal space 110; the shell 100 also has an oil filling hole 112, and an oil filling passage 111 connecting the oil filling hole 112 and the bearing 120; the oil filling hole 112 is used to introduce lubricant for lubricating the bearing 120 into the oil filling passage 111.
[0041] In the disclosed embodiment, the oil filling hole 112 is provided on the housing 100, and the lubricant can be added to the bearing 120 in the bearing seat 150 by using the oil filling hole 112. The lubricant can reduce the wear and corrosion of the bearing 120, extend the service life of the bearing 120, and help dissipate heat. The oil filling hole 112 can also be used to regularly replace the lubricant in the bearing 120 in the internal space 110. When replacing the lubricant, there is no need to disassemble the reducer and / or the drive motor, which is easy to operate, saves manpower and material resources, and improves work efficiency.
[0042] Without limitation, the driving mechanism provided in the embodiment of the present disclosure includes a machine base, a driving motor, a bearing 120, a transmission shaft 130 and a machine base, wherein the transmission shaft 130 connecting the driving motor and the reducer passes through the bearing 120, and the driving force output by the driving motor is transmitted to the reducer by the transmission shaft 130. The bearing 120 is located in the machine base to support the transmission shaft 130. In addition to fixing the bearing 120, the machine base can also fix the driving motor and the reducer, keep the relative position of the driving motor and the reducer unchanged, provide better support and stability for the driving motor and the reducer, and reduce the noise and vibration generated by the driving motor and the reducer.
[0043] In the embodiment shown in the present disclosure, the driving mechanism is used to drive the rotation of the agitator, but the purpose of the driving mechanism is not limited thereto.
[0044] Exemplarily, the drive mechanism can be used in a semi-open air environment.
[0045] The lubricant may be a solid or semi-solid grease, or the lubricant may be a liquid lubricating oil.
[0046] Figure 1 and Figure 3 One oil injection hole 112 is shown as an example. It is understandable that there may be two or more oil injection holes 112, for example, three or four oil injection holes 112.
[0047] Exemplarily, the bearing seat 150 can be connected and fixed to the bearing 120 by means of screw fixing, snap fixing, interference fit, etc.
[0048] Optionally, the bearing seat 150 may be entirely, partially, or partially located in the internal space 110 , or the bearing seat 150 may not be located in the internal space 110 .
[0049] The use of the oil filling hole 112 to replenish lubricant for the bearing 120 includes but is not limited to the following two methods: the first is to directly pass the lubricant into the oil filling hole 112; the second is to install a connecting tube or a connecting nozzle 140 in the oil filling hole 112 and use the connecting tube or the connecting nozzle 140 to pass the lubricant.
[0050] In the embodiment shown in the present disclosure, the lubricant is injected by means of the connection nozzle 140. Figures 1 to 3 As shown, the base further includes: a connecting nozzle 140, which is connected to the housing 100, and the connecting nozzle 140 has a through hole for the lubricant to pass through. The through hole is for the lubricant to pass through.
[0051] The connection nozzle 140 can be better connected with the oil filling equipment to facilitate the oil filling operation.
[0052] Without limitation, the connection nozzle 140 can be made of brass. The connection nozzle 140 has a thread, and the through hole size of the connection nozzle 140 is approximately M8*1.0 (ie, the hole diameter is 8 mm, and the thread pitch is 1.0 mm). The size of the connection nozzle 140 can be selected as needed and is not limited thereto.
[0053] like Figure 2 As shown, optionally, a portion of the connection nozzle 140 is inserted into the oil filling hole 112, and another portion protrudes from the outer wall of the housing 100. The portion of the connection nozzle 140 protruding from the outer wall of the housing 100 can be inserted into the muzzle of the oil filling device, reducing the leakage of lubricant and facilitating the oil filling operation.
[0054] like Figure 1 As shown, optionally, a portion of the internal space 110 above the bearing seat 150 forms an oil injection passage 111.
[0055] It is understandable that in an embodiment not shown in the present disclosure, the oil injection passage 111 may also be formed by a pipe located in the internal space 110. This solution requires the use of a pipe to separately construct the oil injection passage 111. However, the embodiment of the present disclosure uses the space inside the housing 100 to form the oil injection passage 111, and there is no need to separately construct the oil injection passage 111, which is conducive to cost saving.
[0056] Optionally, the bearing 120 of the embodiment of the present disclosure is an open bearing 120 . When lubricant is introduced through the oil filling hole 112 , the lubricant will accumulate in the oil filling channel, and the accumulated lubricant will generate pressure to squeeze the lubricant into the interior of the bearing 120 .
[0057] like Figure 1 and Figure 3 As shown, according to some optional embodiments, the oil filling hole 112 is opened on the part of the housing 100 above the bearing seat 150.
[0058] Without limitation, at least part of the inner space 110 of the housing 100 is substantially cylindrical, and the axis of the bearing 120 coincides with the axis of the inner space 110 of the housing 100. At least a certain space above the transmission shaft 130 (also above the bearing seat 150) is provided as an oil injection channel, and an oil injection hole 112 leading to the oil injection channel can be provided above the housing 100.
[0059] Opening the oil filling hole 112 above the housing 100 not only facilitates the oil filling operation, but also allows the lubricant to flow to the bearing 120 by gravity and fluidity, thereby improving the oil filling efficiency.
[0060] Figure 3 It is exemplarily shown that the bearing seat 150 includes one and the bearing 120 includes one. Figure 1 It is shown by way of example that there are two bearing seats 150, each bearing seat 150 is mounted with a bearing 120, the two bearings 120 are coaxially distributed, and the oil injection hole 112 is located above the two bearing seats 150 and between the two bearing seats 150. In addition, there may be three or more bearing seats 150. The number of bearing seats 150 is not intended to limit the embodiments of the present disclosure.
[0061] Regardless of the number of the oil injection holes 112, all the oil injection holes 112 can provide lubricant to all the bearing seats 150 through the same oil injection hole 112 and the same oil injection passage 111. Figure 1 As shown, the two bearings 120 can be replenished with lubricant at the same time through the upper oil filling hole 112 .
[0062] According to some optional embodiments, the base also includes: a first mounting portion 102 and a second mounting portion 101, the first mounting portion 102 is located at the first end of the shell 100, and the first mounting portion 102 is used to install the drive motor to fix the drive motor; the second mounting portion 101 is located at the second end of the shell 100, and the second mounting portion 101 is used to install the reducer to fix the reducer; wherein the second end is the opposite end of the first end, and the transmission shaft 130 connects the drive motor and the reduction device, and transmits the driving force provided by the drive motor to the reducer.
[0063] The reducer can convert the high-speed rotation output by the drive motor into the lower speed and high torque required by the agitator through an internal reduction device (such as a gear structure). This enables the agitator to handle larger material loads and resistance while providing sufficient stirring capacity. The stirring speed can be precisely controlled by adjusting the transmission ratio of the reducer. In chemical reactions, precise stirring speeds are required to ensure that the reactants are mixed evenly and to control the reaction rate. Because the high-speed rotation of the drive motor is converted into a low-speed rotation, the load on the motor is reduced, the service life of the motor is increased, and the efficiency is improved.
[0064] Exemplarily, the reducer may be a sew RF reducer, wherein sew represents the brand of the reducer and RF represents the model of the reducer. The reducer is not limited thereto.
[0065] The first mounting portion 102 and the second mounting portion 101 may be integral components that are physically inseparable from the shell 100. For example, the first mounting portion 102, the second mounting portion 101 and the shell 100 may be integrally formed by machining or mold opening. Alternatively, the first mounting portion 102 and the second mounting portion 101 may be split components that are physically separable from the shell 100, so that the first mounting portion 102 and the second mounting portion 101 may be fixed to the shell 100 respectively by fasteners such as screws.
[0066] According to some optional embodiments, the base further includes: a sealing member located at the connection between the housing 100 and the driving motor, and the sealing member is used to form a seal at the connection between the housing 100 and the driving motor.
[0067] Without limitation, the sealing member is a sealant.
[0068] The seal can limit moisture or dust in the external environment from entering the interior of the housing 100 through the drive motor side, reduce moisture corrosion to the bearing 120, and further increase the service life of the bearing 120.
[0069] like Figure 1 and Figure 3 As shown, according to some optional embodiments, the first mounting portion 102 includes: a first flange connected to the first end of the housing 100 , and the second mounting portion 101 includes: a second flange connected to the second end of the housing 100 .
[0070] Typically, the drive motor and the reducer also have flanges respectively. The flange on the drive motor is connected to the first flange, and the flange on the reducer is connected to the second flange. The output shaft of the drive motor and the input shaft of the reducer are respectively connected to the two ends of the transmission shaft 130.
[0071] In some usage scenarios, the drive mechanism disclosed in the present invention is used, for example, for stirring semi-open-air chemical equipment, and lubricant is added to the bearing 120 through the oil filling hole 112, so that the service life of the bearing 120 can be extended to one or two years.
[0072] The following table shows the operating temperature of the reducer and the operating current of the drive motor when there is no oil injection hole 112 (i.e. before improvement) and when the oil injection hole 112 is added (i.e. after improvement).
[0073]
[0074] As can be seen from the above table, after adding the oil injection hole 112, the operation of the drive motor and the reducer is still relatively stable, ensuring the full lubrication of the bearing 120 in the machine base, which can effectively reduce wear and dissipate heat in time, and can also effectively prevent moisture from entering, reduce maintenance and repair costs, and improve efficiency.
[0075] Under the premise of no conflict, different embodiments or different technical features of the present disclosure can be arbitrarily combined to form new embodiments.
[0076] It should be understood that the above embodiments are exemplary and are not intended to include all possible implementations included in the claims. Various modifications and changes may be made on the basis of the above embodiments without departing from the scope of the present disclosure. Similarly, the various technical features of the above embodiments may be arbitrarily combined to form other embodiments of the utility model that may not be explicitly described. Therefore, the above embodiments only express several implementations of the utility model and do not limit the scope of protection of the utility model patent.
