Description

TECHNICAL FIELD

[0001] The application belongs to the field of mining machinery equipment, and particularly relates to a vibration exciter box. BACKGROUND

[0002] The vibration exciter is a key component commonly used in mining machinery equipment, and the box structure thereof directly affects the running stability, lubrication effect and service life of the equipment. In the existing design of the vibration exciter box, the structure usually comprises a body, a lubricating cavity and a bearing base, and the lubricating cavity is used for storing lubricating oil to ensure the normal operation of the bearing. However, the connection structure of the bearing base and the lubricating cavity in the traditional design is relatively simple, and the flowability of the lubricating oil is insufficient, which can easily lead to uneven lubrication or poor heat dissipation of the bearing. In addition, the overall strength and rigidity of the box also have certain deficiencies, especially under the conditions of high load or long-time operation, deformation or fatigue damage can easily occur, which affects the reliability and safety of the equipment. Therefore, an improved vibration exciter box design is urgently needed to improve the lubrication effect, structural strength and service life, and meet the high-performance requirements of the mining machinery equipment. CONTENT OF THE UTILITY MODEL

[0003] The utility model provides a vibration exciter box, aims at solving the problem of poor lubrication effect and insufficient structural strength in the prior art. The following is the specific technical scheme of the utility model and the role and effect of its technical features:

[0004] The utility model relates to a vibration exciter box, which comprises a body, a lubricating cavity and a bearing base. The lubricating cavity is located inside the body, and the bearing base is provided in the lubricating cavity. The axial sides of the bearing base extend outwards from the inner and outer sides of the body side wall. At least one part of the end face of the bearing base on the inner side of the body is provided with a plurality of through grooves. The through grooves are arranged in the radial direction of the bearing base. By extending the axial sides of the bearing base outwards from the inner and outer sides of the body side wall, the support area of the bearing base can be effectively increased, and its stability can be improved. The arrangement of the through grooves improves the flowability of the lubricating oil in the lubricating cavity, so that the lubricating oil can enter the bearing area in the radial direction, thereby improving the lubrication efficiency and reducing the wear of the bearing caused by insufficient lubrication.

[0005] Further, the lubricating cavity is arranged at the upper part of the body, and the two bearing bases are symmetrically distributed on the left and right sides of the lubricating cavity. The through grooves are arranged on the two sides of the bearing base. The lubricating cavity is located at the upper part, which facilitates the natural flow of the lubricating oil to the bearing base by gravity. The symmetric distribution of the two bearing bases can ensure the balanced stress of the box and improve the stability of the overall structure. The arrangement of the through grooves on the two sides of the bearing base further enhances the bidirectional flowability of the lubricating oil, ensuring that the bearing on both sides can be fully lubricated.

[0006] Further, the width of the through-slots is the same as the spacing width between them, and the number of the through-slots is half of the circumference of the bearing base. The design of the same width of the through-slots and the spacing width makes the distribution of the lubricating oil more uniform, avoiding the phenomenon of local excess or deficiency; the number of the through-slots occupying half of the circumference ensures sufficient flow area and retains the structural strength of the bearing base, achieving the balance of lubrication effect and strength.

[0007] Further, the lateral depth of the through-slots extends beyond the side edge of the bearing outer ring and is close to the middle of the outer wall of the bearing outer ring. The depth of the through-slots beyond the side edge of the bearing outer ring and close to the middle of the outer wall can ensure that the lubricating oil directly acts on the key friction area of the bearing, enhancing the lubrication and cooling effect, thereby prolonging the service life of the bearing.

[0008] Further, a plurality of reinforcing plates are arranged between the bottom plate of the lubricating cavity and the bottom plate of the body. The arrangement of the reinforcing plates significantly improves the connection strength of the lubricating cavity bottom plate and the body bottom plate, reduces the risk of deformation of the box under vibration or impact load, and improves the rigidity and durability of the overall structure.

[0009] Further, an internal reinforcing rib connected with the inner wall of the lubricating cavity is arranged on the inner wall of the bearing base. The internal reinforcing rib enhances the connection rigidity between the bearing base and the lubricating cavity, reduces the slight displacement or vibration of the bearing base under high load, ensures the stability of the bearing operation, and also improves the overall fatigue resistance of the box.

[0010] Further, a plurality of external reinforcing ribs are arranged on the front and rear plate surfaces of the body. The arrangement of the external reinforcing ribs further improves the bending resistance of the front and rear plate surfaces of the body, making the box less likely to deform under external impact or long-term operation, thereby ensuring the long-term reliability of the equipment.

[0011] Further, lug ears are arranged on both sides of the body. The arrangement of the lug ears facilitates the installation and disassembly of the box, improves the convenience of the equipment in actual application, and also facilitates transportation and maintenance.

[0012] Advantages

[0013] 1. Improved lubrication effect: By arranging through-slots on the bearing base and optimizing their position, number and depth, the present utility model significantly improves the flowability and uniformity of the lubricating oil, so that the bearing can be fully lubricated and cooled, reducing wear and failure rate.

[0014] 2. Enhanced structural strength: The arrangement of reinforcing plates between the lubricating cavity and the body, internal reinforcing ribs connected with the inner wall of the lubricating cavity of the bearing base, and external reinforcing ribs on the body collectively improve the rigidity and anti-deformation ability of the box, making it suitable for the high-load working environment of mining machinery.

[0015] 3. Improve the running stability: the extension design and symmetrical distribution of the bearing base, as well as the supporting effect of the internal reinforcing rib, ensure the balance and stability of the box during operation, and reduce the occurrence of vibration.

[0016] 4. Easy to install and maintain: the design of the two side hanging ears improves the installation convenience of the box, and facilitates the operation and maintenance in actual application.

[0017] Prolong the service life: by optimizing lubrication and enhancing structural strength, the utility model effectively reduces the wear and fatigue damage of key components, thereby prolonging the service life of the exciter box. BRIEF DESCRIPTION OF DRAWINGS

[0023] The present application will be described in detail below with reference to the accompanying drawings, to further illustrate its structural features and implementation modes. It should be noted that the present embodiment is only a preferred implementation of the present application, and does not constitute a limitation on the scope of protection of the present application.

[0024] The present application provides an exciter box, the overall structure of which is shown in Figure 1 , mainly including the body 1, the lubrication cavity 2 and the bearing base 3 and other core components. The body 1 is the main frame of the exciter box, made of high-strength metal material (such as cast steel or alloy steel), with good impact resistance and fatigue resistance. The body 1 is in the form of a rectangular box structure, and its internal space is reasonably divided to accommodate the lubrication cavity 2 and other components.

[0025] The lubrication cavity 2 is arranged at the upper part of the body 1, as shown in the front view of Figure 2 and the sectional view of Figure 3The cross-sectional view shows that it is a closed cavity for storing lubricating oil to ensure the normal operation of the bearing. The bottom plate 10 of the lubricating cavity 2 is connected with the bottom plate 11 of the body 1 by several reinforcing plates 5, which are evenly distributed along the length direction of the lubricating cavity 2. Each reinforcing plate 5 is in the shape of a rectangular thin plate, which is vertically welded between the bottom plate 10 of the lubricating cavity and the bottom plate 11 of the body 1. This design can effectively disperse the vibration load and improve the overall rigidity and durability of the box, as shown in Figure 3 The top of the lubricating cavity 2 is usually provided with an oil port (not shown in the figure) to facilitate the addition and replacement of lubricating oil.

[0026] The bearing base 3 is a key supporting structure in the lubricating cavity 2, and two bearing bases 3 are symmetrically distributed on the left and right sides of the lubricating cavity 2, as shown in Figure 2 and Figure 4 Each bearing base 3 is in the shape of a circular ring, and its two axial sides extend to the inner and outer sides of the side wall 9 of the body 1, forming a structure that penetrates the side wall 9. This design increases the support length of the bearing base 3, making it more stable to fix the bearing and withstand larger axial loads. The inner side end face of the bearing base 3 (i.e. the side close to the inside of the lubricating cavity 2) is provided with several through grooves 4, and the opening direction of the through grooves 4 is directed to the radial direction of the bearing base 3, as shown in the partial cross-sectional view of Figure 4 The width of the through groove 4 is equal to the interval width between them, and the number of through grooves 4 accounts for half of the circumference of the bearing base 3. For example, if the end face circumference of the bearing base 3 can accommodate 10 through grooves 4, then 5 through grooves 4 are actually provided and evenly distributed on the circumference. The lateral depth of the through groove 4 extends to exceed the side edge of the bearing outer ring and is close to the middle part of the outer wall of the bearing outer ring. This depth design ensures that the lubricating oil can flow directly into the key friction area of the bearing through the through groove 4, thereby improving the lubrication efficiency and heat dissipation effect.

[0027] In order to further enhance the structural strength, the inner wall of the bearing base 3 is provided with an internal reinforcing rib 6 connected with the inner wall of the lubricating cavity 2, as shown in Figure 3 The internal reinforcing rib 6 is in the shape of a strip, extending along the axial direction of the bearing base 3, with one end welded to the inner wall of the bearing base 3 and the other end connected with the inner wall of the lubricating cavity 2. Each side of the bearing base 3 is usually provided with 2-4 internal reinforcing ribs 6. This design not only enhances the stability of the bearing base 3, but also reduces its small displacement under high load, ensuring the smoothness of the bearing operation.

[0028] The front and rear plates of the body 1 are provided with several external reinforcing ribs 7, as shown in the perspective view of Figure 1 and Figure 2The external reinforcing ribs 7 are long strips arranged vertically along the height direction of the body 1, usually 3-5 external reinforcing ribs 7 are arranged on each plate surface, and the width and thickness of the external reinforcing ribs 7 are designed according to the size and load requirement of the box. The addition of the external reinforcing ribs 7 significantly improves the bending resistance of the front and rear plate surfaces of the body 1, so that the box can still maintain stable shape in the high vibration environment of the mining machinery.

[0029] In addition, the body 1 is also provided with a hanging ear 8 on both sides, as shown in Figure 1 and Figure 2 The hanging ear 8 is an ear-shaped protruding structure located at the upper part of the side wall 9 of the body 1, and one is arranged on each side. A circular mounting hole is formed on the hanging ear 8, which facilitates the use of hoisting equipment or bolts to fix the box on the exciter equipment. The design of the hanging ear 8 improves the convenience of installation and disassembly, and facilitates on-site operation and maintenance.

[0030] In summary, the exciter box of the embodiment realizes the dual improvement of lubrication effect and structural strength through the reasonable layout of the lubricating cavity 2 and the bearing base 3, and the auxiliary structure optimization design of the through slot 4, the reinforcing plate 5, the internal reinforcing rib 6 and the external reinforcing rib 7. Figure 1 The overall three-dimensional structure is shown, Figure 2 and Figure 3 The relative position and connection relationship of each component are clearly presented from the front and sectional views, Figure 4 and the distribution and depth characteristics of the through slot 4 are further revealed through the top view and the partial sectional view. The embodiment is suitable for the field of mining machinery, and can effectively meet the requirements of high load and long time operation, and has high practical value.

[0031] The above is a specific embodiment of the present application, and the technician can adjust the component size, quantity or material according to the actual needs, as long as it meets the technical features of the present application, it falls within the protection scope of the present application.
