[0028] As shown in Figures 1-4 The utility model discloses a novel vibrating screen motor seat, including base 1 and cover plate 2, for installing vibration motor on cover plate 2. Cover plate 2 is rotatably connected with one end of base 1 through main shaft 3, and the other end is connected through spring assembly. Spring assembly includes adjusting rod 4.1, adjusting rod 4.1 passes through cover plate 2 and base 1, adjusting plate 4.2 is arranged on the upper end of adjusting rod 4.1, first spring 4.3 and second spring 4.4 are sleeved on adjusting rod 4.1, wherein first spring 4.3 is arranged between cover plate 2 and base 1, and second spring 4.4 is arranged between cover plate 2 and adjusting plate 4.2. Based on the adjustment of adjusting plate 4.2 along the axial direction of adjusting rod 4.1, the installation angle of cover plate 2 relative to base 1 can be adjusted, and the tension of first spring 4.3 and second spring 4.4 can be changed to realize the adjustment of vibration amplitude and frequency. The technical scheme introduces spring assembly and adjustable adjusting plate 4.2, effectively solves the problems of fatigue fracture of main shaft 3 and limited vibration adjustment of traditional vibrating screen motor seat under long-term high-frequency vibration. The first spring 4.3 and the second spring 4.4 in the spring assembly can change the tension by adjusting the adjusting plate 4.2, so as to adjust the installation angle of the cover plate 2 relative to the base 1, and realize the adjustment of the vibration amplitude and the frequency. Specifically, when the adjusting plate 4.2 moves along the axial direction of the adjusting rod 4.1, the tension of the second spring 4.4 is directly adjusted. Since the first spring 4.3 and the second spring 4.4 are respectively arranged on the two sides of the cover plate 2, the elastic force on the upper and lower sides of the cover plate 2 is further affected, so that the installation angle of the cover plate 2 is adjusted around the main shaft 3. This design not only disperses the stress of the main shaft 3 and reduces the local stress peak, but also provides flexible vibration parameter adaptation capability and enhances the stability and service life of the equipment. Compared with the prior art, the technical scheme of the application has higher reliability and wider applicability.
[0029] In specific embodiments, the adjusting rod 4.1 is constructed as a screw rod, and the adjusting plate 4.2 is threadedly engaged on the screw rod, so that rotating the adjusting plate 4.2 can cause it to move axially along the adjusting rod 4.1.
[0030] The screw is threadedly engaged on the screw rod, thereby achieving precise axial movement. In addition, the screw rod can be made of high-strength alloy steel or stainless steel to improve its wear resistance and fatigue resistance. The material of the adjusting plate 4.2 can be selected from aluminum alloy or engineering plastic to reduce the overall weight and improve the convenience of operation. Thus, the technical solution achieves the precise movement of the adjusting plate 4.2 along the adjusting rod 4.1 by the threaded engagement design of the screw and the adjusting plate 4.2, thereby enabling the adjustment of the installation angle of the cover plate 2 relative to the base 1 and changing the tension of the first spring 4.3 and the second spring 4.4, and further achieving the adjustment of the vibration amplitude and frequency. Compared with the prior art, the design not only improves the precision and stability of the adjustment, but also simplifies the operation steps and reduces the risk of equipment damage caused by improper adjustment. Specifically, by rotating the adjusting plate 4.2, the tension of the spring can be quickly and accurately adjusted, avoiding the cumbersome process of disassembly and reinstallation in the traditional fixed layout. In addition, the threaded engagement design of the screw and the adjusting plate 4.2 also provides a self-locking function to prevent adjustment failure due to loosening during vibration, further improving the reliability and service life of the equipment.
[0031] As shown in Figure 3 The upper end of the base 1 is provided with a support seat 5, and the main shaft 3 is fixed on the support seat 5. The cover plate 2 is rotatably arranged on the main shaft 3 through a bearing set. The number of support seats 5 can be adjusted according to actual needs to ensure that the two ends of the main shaft 3 can be firmly fixed, thereby enhancing the stability of the main shaft 3. The use of the bearing set enables the cover plate 2 to rotate flexibly, reduces friction and wear, and improves the durability and operating efficiency of the overall structure. Specifically, the bearing set can include deep groove ball bearings or other types of bearings to ensure that the cover plate 2 can rotate smoothly on the main shaft 3. Thus, the technical solution effectively solves the problems of unstable fixation of the main shaft 3 and inflexible rotation of the cover plate 2 by providing the support seat 5 and the bearing set. The support seat 5 provides a stable support structure to ensure that the two ends of the main shaft 3 can be firmly fixed, thereby enhancing the stability of the main shaft 3. The use of the bearing set enables the cover plate 2 to rotate flexibly, reduces friction and wear, and improves the durability and operating efficiency of the overall structure. Compared with the prior art, the technical solution not only improves the stability and durability of the vibrating screen motor base, but also significantly improves the overall performance and reliability of the equipment.
[0032] In a specific scheme, the number of support seats 5 is at least two, and the two ends of the main shaft 3 are fixed on the two support seats 5 respectively. By increasing the number of support seats 5, the two ends of the main shaft 3 are fixed on the two support seats 5 respectively, thereby improving the fixing stability of the main shaft 3 and solving the technical problem of unstable fixing of the main shaft 3 caused by insufficient number of support seats 5. As a preferred embodiment, the support seat 5 can be made of high-strength steel to ensure its durability in a high-frequency vibration environment. Further, the connection mode of the support seat 5 and the main shaft 3 can adopt bolt fixing or tight fitting, etc., to enhance the firmness of the connection. In addition, the design of the support seat 5 can include reinforcing ribs to improve the overall structural strength, thereby better resisting vibration load. Therefore, by increasing the number of support seats 5, the two ends of the main shaft 3 are fixed on the two support seats 5 respectively, which can effectively disperse the stress borne by the main shaft 3 and reduce local stress concentration, thereby significantly improving the fixing stability of the main shaft 3. Compared with the prior art, the technical scheme not only solves the problem of unstable fixing of the main shaft 3 caused by insufficient number of support seats 5, but also further improves the reliability and durability of the overall structure by optimizing the structure and connection mode of the support seat 5.
[0033] Further, the lower end surface of the cover plate 2 is provided with a bearing mounting plate 7; a bearing 8 is arranged in the bearing cavity 7.1 of the bearing mounting plate 7;
[0034] When the cover plate 2 is installed on the base 1, the main shaft 3 is arranged in the bearing inner ring of the bearing 8. Specifically, the design of the bearing mounting plate 7 can adopt various forms. For example, the bearing mounting plate 7 can be fixed on the lower end surface of the cover plate 2 by welding or bolt connection. The shape and size of the bearing cavity 7.1 can be customized according to the type and size of the bearing 8 to ensure that the bearing 8 can be stably installed in the cavity. The bearing 8 can adopt a deep groove ball bearing, the inner ring of which is tightly matched with the main shaft 3, and the outer ring is tightly matched with the bearing cavity 7.1. For this purpose, the technical scheme of the present application can stably install the bearing 8 on the cover plate 2 by arranging the bearing mounting plate 7, ensure the connection stability between the main shaft 3 and the cover plate 2, reduce the vibration transmission, and improve the stability of the overall structure. By arranging the main shaft 3 in the inner ring of the bearing 8, the connection strength between the main shaft 3 and the cover plate 2 is further enhanced, effectively solving the problem of insufficient connection stability between the cover plate 2 and the main shaft 3. Compared with the prior art, the technical scheme of the present application not only improves the connection stability, but also reduces the direct impact of vibration on the main shaft 3 through the installation mode of the bearing 8, prolongs the service life of the equipment.
[0035] In specific solutions, the two ends of the main shaft 3 extend out of the support base 5; the number of bearing mounting plates 7 is at least two, and they are located outside the support base 5; the extended sections at the two ends of the main shaft 3 are arranged in the bearing inner rings of the bearings 8. The design that the two ends of the main shaft 3 extend out of the support base 5 can improve the installation stability of the main shaft 3 by increasing the support length of the main shaft 3. The bearing mounting plates 7 are located outside the support base 5, which can further enhance the support effect on the main shaft 3 and reduce vibration transmission. The extended sections at the two ends of the main shaft 3 are arranged in the bearing inner rings of the bearings 8, which ensures the close fit between the main shaft 3 and the bearings 8 and reduces vibration and noise during operation. Therefore, the technical solution effectively solves the problem of installation stability of the main shaft 3 outside the support base 5 by extending the two ends of the main shaft 3 out of the support base 5 and adding bearing mounting plates 7 outside. At the same time, the close fit between the main shaft 3 and the bearings 8 reduces vibration transmission and improves the running stability of the equipment. Compared with the prior art, the solution significantly improves the overall stability and service life of the equipment by optimizing the structure layout and adding support points.
[0036] Further, the bearings 8 are deep groove ball bearings. Deep groove ball bearings are a common type of rolling bearing, which are characterized by having balls arranged between the inner and outer rings and evenly distributed by a retainer. Deep groove ball bearings have high load-carrying capacity and good rotational accuracy, and are suitable for bearing radial and axial loads. In the vibrating screen motor base, the use of deep groove ball bearings can effectively reduce the friction between the main shaft 3 and the bearings 8, improve the rotational efficiency, and enhance the durability and stability of the bearings 8. Specifically, the contact area between the balls of the deep groove ball bearing and the inner and outer rings is large, which can evenly distribute the load and reduce local stress concentration, thereby prolonging the service life of the bearings 8. Therefore, the application of deep groove ball bearings solves the technical problem of bearing type selection in the vibrating screen motor base. By using deep groove ball bearings, the friction between the main shaft 3 and the bearings 8 is reduced, the rotational efficiency is improved, and the durability and stability of the bearings 8 are also enhanced. Compared with the prior art, the use of deep groove ball bearings not only improves the operating efficiency of the vibrating screen motor base, but also reduces equipment failures caused by bearing 8 wear, thereby prolonging the service life of the equipment. Therefore, the application of deep groove ball bearings has significant technical advantages in the vibrating screen motor base.
[0037] As shown in Figure 3 the inner side wall of the bearing mounting plate 7 is provided with a through hole 7.2 for the end of the main shaft 3 to extend into the bearing cavity 7.1; the outer side wall of the bearing mounting plate 7 is provided with a mounting opening 7.3 for dismounting the bearings 8; the outer side wall of the bearing mounting plate 7 is also provided with a plurality of mounting holes 7.4 for mounting the bearings 8.
[0038] A cover plate 7.4 is provided to cover the installation port 7.3. Specifically, the design of the through hole 7.2 allows the spindle 3 to smoothly extend into the bearing chamber 7.1, simplifying the installation process of the spindle 3. The design of the installation port 7.3 facilitates the disassembly and assembly of the bearing 8, improving the maintenance efficiency. The design of the cover plate 7.4 is used to cover the installation port 7.3, preventing dust and impurities from entering the bearing chamber 7.1, ensuring the normal operation of the bearing 8. Among them, the diameter of the through hole 7.2 can be adjusted according to the size of the spindle 3 to ensure that the spindle 3 can smoothly pass through. The size and shape of the installation port 7.3 can be designed according to the size of the bearing 8 and the requirements of the disassembly tool to improve the convenience of operation. The cover plate 7.4 can be detachable or rotatable to facilitate opening or closing when the bearing 8 needs to be disassembled. Thus, through the mutual cooperation of the above technical features, the technical problem of inconvenient operation of the bearing installation plate 7 during the installation of the spindle 3 and the disassembly and assembly of the bearing 8 is effectively solved. Among them, the design of the through hole 7.2 and the installation port 7.3 simplifies the installation of the spindle 3 and the disassembly and assembly of the bearing 8, reducing the operation time and labor intensity. The design of the cover plate 7.4 effectively prevents dust and impurities from entering the bearing chamber 7.1, prolonging the service life of the bearing 8. Compared with the prior art, the technical scheme of the present application improves the operation convenience and maintenance efficiency, and also enhances the protection performance of the bearing 8, which has significant practicality and innovation.
[0039] Further, a plurality of strip-shaped holes 2.1 for fixing the motor are provided on the cover plate 2. The design of these strip-shaped holes 2.1 allows the position of the motor on the cover plate 2 to be adjusted as needed and ensures that the motor does not loosen or fall off during vibration. The provision of strip-shaped holes 2.1 not only improves the stability of the motor installation, but also enhances the overall stability and service life of the vibrating screen. Specifically, the strip-shaped holes 2.1 can be implemented in various ways. For example, the strip-shaped holes 2.1 can be designed as long strip-shaped through holes, the length and width of which can be adjusted according to the size of the motor and the installation requirements. In addition, the positions of the strip-shaped holes 2.1 can be evenly distributed on the cover plate 2 so that the motor can be stably fixed at different positions. In this regard, by providing a plurality of strip-shaped holes 2.1 on the cover plate 2, the installation position of the motor can be flexibly adjusted according to actual needs, thereby ensuring the stability of the motor during vibration. This design not only solves the problem of unstable motor installation in traditional vibrating screens, but also improves the overall performance and reliability of the equipment. Compared with the prior art, the technical scheme of the present application significantly improves the practicality and service life of the vibrating screen through simple structural improvement.
