Description

Technical Field

[0001] This utility model belongs to the field of gear support technology, and in particular relates to a bearing support structure for a large gear of a necking machine. Background Technology

[0002] When the 6800 necking machine is running at a speed of 2200 CPM or higher, friction will occur between the bearing and the bearing support of the gears at stations 1 to 17 under high-speed operation. After long-term operation, this will cause wear on the inner ring of the bearing support, increasing the clearance and causing the bearing and the main shaft to move internally. It will also cause excessive wear between the bearing and the inner ring of the support, leading to frequent equipment failures.

[0003] In the prior art, such as the bearing bracket disclosed in Chinese Patent (CN203343916U), a cavity for placing the bearing to be assembled is provided on the end face of the support. An elastic element is provided on the side of the cavity. One end of the elastic element is fixed on the support, and the other end abuts against the bearing to be assembled. The bearing is placed in the cavity, and the elastic element abuts against the bearing.

[0004] The existing technology has the following drawbacks: 1. Under prolonged high-speed operation, friction will occur between the bearing and the bearing support. After long-term operation, the inner ring of the bearing support will wear, increasing the clearance and causing the bearing and spindle to move internally, leading to frequent equipment failures. 2. Although the existing technology uses elastic elements between the bearing and the support to provide cushioning, the clamping structure and elastic elements in this device are not suitable for the high-speed rotating bearing operation. 3. The existing technology requires regular lubrication of the bearing support after installation to ensure lubrication between the bearing and the support and reduce wear. In the existing technology, due to the need to protect the internal structure, a shell needs to be installed on the outside of the bearing support. Lubrication requires removing the shell, which is time-consuming and labor-intensive. Furthermore, opening the shell can easily allow dust to fall into the internal structure and cause contamination.

[0005] Therefore, this utility model provides a bearing support structure for a large gear of a necking machine. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] The prior art in this embodiment has the following problems: The inventors have found the following defects in the prior art: First, under long-term high-speed operation, inner ring wear will occur between the bearing and the bearing support, which will increase the gap and cause the bearing and the main shaft to move internally, resulting in frequent equipment failures; Second, although the prior art has set up elastic elements between the bearing and the support to provide cushioning, the clamping structure and elastic elements in the device are not suitable for the operating conditions of high-speed rotating bearings; Third, when replenishing lubrication, the outer shell needs to be removed, which is time-consuming and laborious, and opening the outer shell can easily cause dust to fall into the internal structure and cause contamination.

[0025] Therefore, the inventor provides a bearing support structure for a large gear of a necking machine, including a flange mounting plate 1, a housing 2, a mounting groove 3, and a bearing 4. The flange mounting plate 1 is located below the housing 2, the mounting groove 3 is located inside the housing 2, and the bearing 4 is located on the mounting groove 3 inside the housing 2. A quick-access lubrication interface mechanism 7 is provided on the right side of the housing 2. An O-ring 5 is provided between the bearing 4 and the housing 2 to adapt to high-speed operation and facilitate lubrication. A guide vane 6 and a fixing mechanism are provided on the O-ring 5. The guide vane 6 is located above the O-ring 5, and the fixing mechanism is located between the O-ring 5 and the housing 2.

[0026] Using the above scheme, when installing the bearing 4 and the bracket, first put the O-ring 5 on the outside of the bearing 4, and then install the bearing 4 into the mounting groove 3 on the inside of the housing 2 and fix it. Then, install the bearing 4 on the side of the large gear of the necking machine through the flange mounting plate 1. During use, lubricating oil can be added to the bearing 4 inside the housing 2 through the interface mechanism. After the lubricating oil enters from the interface mechanism 7, it flows along the inner wall of the housing 2, is guided by the O-ring 5, and enters the bearing 4 for lubrication. The guide plate 6 above the O-ring 5 can introduce the lubricating oil into the side of the bearing 4 in the O-ring 5, and then introduce the lubricating oil from the side of the bearing 4 to lubricate the bearing 4. The fixing mechanism can fix the O-ring 5 in the mounting groove 3 on the inside of the housing 2 to prevent the O-ring 5 from moving inside the mounting groove 3 when the bearing 4 rotates. Example 1

[0027] like Figures 1 to 4 As shown

[0028] Furthermore, the interface mechanism 7 also includes a tapered connector and a leather cap (not shown in the figure), and the leather cap and the tapered connector are fastened together by a groove on the side of the tapered connector;

[0029] Furthermore, the interface mechanism 7 also includes a threaded connector and a nut (not shown in the figure), with the nut threadedly connected to the threaded connector;

[0030] Furthermore, a threaded oil guide groove 8 is provided on the inner side of the outer casing 2, and the threaded oil guide groove 8 is located on the lower side of the interface mechanism 7.

[0031] When the bearing 4 is in operation, the interface mechanism 7 is closed to prevent dust from entering the housing 2 and causing contamination. When lubrication is required, remove the cap on the tapered connector or unscrew the nut on the threaded connector, connect the lubricating oil pipe to the connector, and slowly pump the lubricating oil into the housing 2 through the oil pump. When installing the bracket, the flange mounting plate 1 needs to be installed with the interface mechanism 7 facing upward. The lubricating oil enters the interface port and is transmitted to the top of the O-ring 5 through the threaded oil guide groove 8 on the inner side of the housing 2. Then, the lubricating oil is evenly introduced into the bearing 4 from the O-ring 5 along the threaded structure for lubrication.

[0032] In this way, the guide plate 6, together with the interface mechanism 7, lubricates the bearing 4 inside the bracket without opening the outer shell 2. This method is simple, efficient, and saves time and effort. Example 2

[0033] like Figure 3 As shown

[0034] Furthermore, a fixing piece 9 is provided below the O-ring 5;

[0035] Furthermore, a fixing groove matching the fixing piece 9 is provided on the inner side below the mounting groove 3, and the lower end of the fixing groove is tapered;

[0036] In this process, after the fixing piece 9 is installed into the mounting groove 3, the fixing piece 9 below the O-ring 5 is inserted into the fixing groove. The lower end of the fixing groove contracts, squeezing and fixing the front end of the fixing piece 9, thereby fixing the entire O-ring 5 and achieving the effect of fixing the bearing 4. Example 3

[0037] like Figure 4 As shown

[0038] Furthermore, a fixing stripe 10 is provided on the outer side of the O-ring 5;

[0039] Furthermore, the inner side of the mounting groove 3 is provided with a groove that matches the fixing stripe 10;

[0040] In this design, after the O-ring 5 is inserted into the fixing groove, the fixing stripe 10 is inserted into the groove inside the mounting groove 3 to fix the O-ring 5. The fixing stripe 10 and the groove can be set to surround the O-ring 5 or be set vertically outside the O-ring 5 according to the vibration conditions of the equipment. In this way, by setting the O-ring 5 between the bearing 4 and the bracket, elastic buffering is provided between the bearing 4 and the bracket, reducing wear on the inner side of the bearing 4 and the bracket, and reducing equipment failure caused by wear. In addition, this method can effectively fix the O-ring 5 and the bearing 4. The structure is simple and practical, suitable for high-speed operating bearing 4 brackets, and has high reliability.

[0041] In summary, this device incorporates an O-ring 5 with a guide vane 6 and a fixing mechanism to provide elastic buffering between the bearing 4 and the bracket, reducing wear on the inner side of the bearing 4 and the bracket, and minimizing equipment failures caused by wear. Furthermore, this method effectively secures the O-ring 5 to the bearing 4, and its simple and practical structure makes it suitable for high-speed operating bearing 4 brackets with high reliability. The guide vane 6, in conjunction with the interface mechanism 7, lubricates the bearing 4 inside the bracket without opening the outer casing 2, a simple, efficient, and labor-saving method.

[0042] The working principle of this utility model:

[0043] When installing the bearing 4 and the bracket, first put the O-ring 5 on the outside of the bearing 4, and then install the bearing 4 into the mounting groove 3 on the inside of the housing 2 and fix it.

[0044] Using the scheme of Embodiment 2, after the fixing piece 9 is installed into the mounting groove 3, the fixing piece 9 below the O-ring 5 is inserted into the fixing groove, the lower end of the fixing groove contracts, and the front end of the fixing piece 9 is squeezed and fixed, thereby fixing the entire O-ring 5 and achieving the effect of fixing the bearing 4.

[0045] In the scheme of embodiment 3, after the O-ring 5 is installed into the fixing groove, the fixing stripe 10 is inserted into the groove on the inner side of the mounting groove 3 to fix the O-ring 5. The fixing stripe 10 and the groove can be set to surround the O-ring 5 or be set vertically on the outside of the O-ring 5 according to the vibration conditions of the equipment. In this way, by setting the O-ring 5 between the bearing 4 and the bracket, elastic buffering is provided between the bearing 4 and the bracket, reducing wear on the inner side of the bearing 4 and the bracket, and reducing equipment failure caused by wear. In addition, this method can effectively fix the O-ring 5 and the bearing 4. The structure is simple and practical, suitable for high-speed operating bearing 4 brackets, and has high reliability.

[0046] Then, the bearing 4 is installed on the side of the large gear of the necking machine through the flange mounting plate 1. During use, lubricating oil can be added to the bearing 4 inside the housing 2 through the interface mechanism. Remove the cap on the tapered joint or unscrew the nut on the threaded joint and connect the lubricating oil pipe to the joint. The lubricating oil is slowly pumped into the housing 2 through the oil pump. When installing the bracket, the flange mounting plate 1 needs to be installed with the interface mechanism 7 facing upward. The lubricating oil enters the interface port and is transmitted to the top of the O-ring 5 through the threaded oil guide groove 8 on the inner side of the housing 2. Then, the lubricating oil is evenly introduced from the guide plate 6 above the O-ring 5 along the thread structure to the side of the bearing 4 in the O-ring 5. The lubricating oil is then introduced from the side of the bearing 4 to lubricate the bearing 4. In this way, the guide plate 6 and the interface mechanism 7 can lubricate the bearing 4 inside the bracket without opening the housing 2. This method is simple, efficient and saves time and effort.

[0047] This concludes the description of the working principle of the device.

[0048] After adopting the above solution, the 6800 necking machine underwent speed-up and stable operation verification. The specific operating conditions are as follows:

[0049] 1. The speed was increased to 2300 cpm and it ran normally for 6 hours.

[0050] 2. Gradually increase the speed to 2350 cpm and run for 1 hour until normal operation is achieved;

[0051] 3. The speed was finally increased to 2400 cpm and it ran normally for 2 hours.

[0052] The operation of the four main drive motors of the 6800 necking machine was verified by gradually increasing the speed. Monitoring data showed that during the speed increase from 2300 cpm to 2400 cpm, the Hertz (Hz) increase range of the four main drive motors was within 2 Hz, the current fluctuation was relatively small, and no harmonic interference or overload phenomenon was observed. This further verified the dynamic balance and reliability of the transmission system, meeting the requirements of high-speed operation.
