Abstract
Description
Technical Field
[0001] This invention relates to the field of exciter technology, and more particularly to an embedded triaxial synchronous exciter. Background Technology
[0002] Most existing triaxial vibrators adopt a traditional single vibrator structure with a synchronizer or a synchronous gear on one side. The phase adjustment structure of the eccentric block is complex, making on-site operation and maintenance difficult. In actual mining, sand and gravel, dry powder, and ore screening conditions, there are obvious defects. Traditional housings are mostly modular, resulting in poor hole position accuracy, weak triaxial synchronization, and easy temperature rise, abnormal noise, and rapid wear during long-term high-load operation.
[0003] To address the common pain points in these industries, there is an urgent need for a new type of triaxial synchronous vibrator that can change the vibration angle, optimize material trajectory, prevent material blockage, and achieve higher precision. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of the existing split-assembly structure and propose an embedded triaxial synchronous vibrator.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a bearing housing base, a synchronous gear, a long shaft, a short shaft, and an eccentric block. The bearing housing base has three sets of bearing housing holes and one synchronous gear insertion hole. The bearing housing base has an oil level indicator hole and an oil drain hole. Two sets of short shafts are located on both sides of the long shaft. The long shaft and short shaft rotate horizontally within the three sets of bearing housing holes. Both ends of the long shaft and short shaft penetrate the bearing housing base. The synchronous gear is located inside the bearing housing base and is fixedly connected to the long shaft and short shaft, with adjacent synchronous gears meshing with each other. The eccentric block is fixedly connected to both ends of the long shaft and short shaft.
[0006] As a further description of the above technical solution: The long shaft and the short shaft are respectively provided with bearing caps that fit into the bearing chamber holes on both sides, and dust covers are respectively fixedly connected to both ends of the long shaft and the short shaft.
[0007] As a further description of the above technical solution: An outer protective cover is connected to one side of the bearing housing base. A fixing hole is provided on the bearing housing base, and the outer protective cover is fixed to the bearing housing base by fasteners inserted into the fixing hole.
[0008] As a further description of the above technical solution: The eccentric blocks on the long axis and the eccentric blocks on the short axis are installed with a 90° phase difference.
[0009] As a further description of the above technical solution: The eccentric block on the long shaft is subjected to force in the opposite direction to the material discharge direction.
[0010] As a further description of the above technical solution: The oil level indicator hole and the oil drain hole are connected to the interior of the bearing housing base, and the oil drain hole is located at the bottom of the bearing housing base.
[0011] The present invention has the following beneficial effects: 0. In this invention, an integral precision-cast bearing housing base is adopted, and the three sets of bearing housing holes and synchronous gear insertion holes are clamped and precision-machined in one go, eliminating the cumulative assembly error of the split assembly structure and improving the parallelism and coaxiality accuracy of the three axes; the built-in three synchronous gear meshing transmission realizes that the long shaft and the two short shafts have the same speed and synchronous operation, ensuring the uniform excitation frequency of the eccentric block and the stable vibration output, effectively solving the problems of poor hole position accuracy and weak three-axis synchronization in traditional split box bodies.
[0012] 0. This invention uses eccentric blocks with a 90° phase difference between the long and short axes to form an elliptical motion trajectory with a 45° vibration direction angle. The force direction of the long axis eccentric block is set opposite to the material discharge direction, so that the material produces a combined vibration effect of oblique projection and layered sliding. This effectively disperses accumulated materials, prevents material jamming and blockage, and improves screening transparency. At the same time, it avoids the problems of rapid material accumulation and insufficient screening.
[0013] 0. In this invention, a multi-layer sealing structure combining a dust cover and a bearing cap is adopted, which effectively prevents dust from entering the cavity under working conditions such as mining and sand and gravel, protects the gears and bearings for long-term stable operation, and reduces temperature rise, abnormal noise and wear rate; with the design of oil level indicator hole and bottom drain hole, the oil level can be observed in real time and the lubricating oil can be replaced quickly, making on-site operation and maintenance simple.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0017] To address the problems in the background art, this application embodiment designs an embedded triaxial synchronous vibrator, including a bearing housing base 1, a synchronous gear 2, a long shaft 3, a short shaft 4, and an eccentric block 5. The bearing housing base 1 has three sets of bearing housing holes 6 and a synchronous gear insertion hole 7 inside. The bearing housing base 1 has an oil level indicator hole 8 and an oil drain hole 9. The short shaft 4 has two sets located on both sides of the long shaft 3. The long shaft 3 and the short shaft 4 rotate horizontally within the three sets of bearing housing holes 6. Both ends of the long shaft 3 and the short shaft 4 pass through the bearing housing base 1. The synchronous gear 2 is located inside the bearing housing base 1 and is fixedly connected to the long shaft 3 and the short shaft 4, with two adjacent synchronous gears 2 meshing with each other. The eccentric block 5 is fixedly connected to both ends of the long shaft 3 and the short shaft 4.
[0018] The oil level indicator hole 8 and the oil drain hole 9 are connected to the inside of the bearing housing base 1, and the oil drain hole 9 is located at the bottom of the bearing housing base 1. The oil level indicator hole 8 and the oil drain hole 9 can be used to observe the oil level in real time and quickly replace the lubricating oil.
[0019] In this embodiment, the bearing housing base 1 adopts an integral precision casting structure. The three sets of bearing housing holes 6 and synchronous gear insertion holes 7 are clamped and precision machined in one go, with no assembly gap, eliminating the cumulative assembly error and ensuring the parallelism and coaxiality accuracy of the three shafts. The three synchronous gears 2 mesh and drive, so that the long shaft 3 and the two short shafts 4 rotate at the same speed and operate synchronously, ensuring that the excitation frequency of the multiple sets of eccentric blocks 5 is uniform and the vibration output is stable.
[0020] In some embodiments, the long shaft 3 and the short shaft 4 are respectively provided with bearing caps 10 that fit into the bearing chamber hole 6 on both sides, and dust covers 11 are respectively fixedly connected to both ends of the long shaft 3 and the short shaft 4.
[0021] One side of the bearing housing base 1 is connected to an outer protective cover 13. The bearing housing base 1 has a fixing hole 12. The outer protective cover 13 is fixed to the bearing housing base 1 by fasteners inserted into the fixing hole 12.
[0022] In this embodiment, the dust cover 11 and the bearing cover 10 are combined to form a multi-layer sealing structure, which prevents dust from entering the cavity and protects the gear and bearing for long-term stable operation.
[0023] In some embodiments, the eccentric block 5 on the long axis 3 and the eccentric block 5 on the short axis 4 are installed with a 90° phase difference, and the operation forms a 45° direction angle and an elliptical motion trajectory; the force direction of the eccentric block 5 on the long axis 3 is set opposite to the material discharge direction.
[0024] Among them, the 90° phase difference of the eccentric block 5 combined with the 45° vibration direction angle makes the material produce a composite vibration effect of oblique projection and layered sliding, which can effectively disperse the accumulated material, prevent material jamming and blockage, and improve the screening throughput.
[0025] The embedded triaxial synchronous vibrator in this embodiment can be applied to material screening, specifically, but not limited to, screening equipment for sand, gravel, dry powder, and ore.
[0026] To better understand the working process of the embedded triaxial synchronous vibrator of this application embodiment, please refer to... Figure 1 - Figure 3 The following is a specific embodiment: During assembly, a long shaft 3 and two short shafts 4 are assembled in parallel into three sets of bearing chamber holes 6. Through the synchronous gear insertion hole 7, three synchronous gears 2 are installed in the middle of the three shafts. The adjacent synchronous gears 2 mesh to achieve complete synchronous rotation of the three shafts.
[0027] Six eccentric blocks 5 are installed at both ends of the three shafts. During the assembly process, the phase is precisely controlled: the middle eccentric block 5 is installed at a 90° phase offset from the eccentric blocks 5 at both ends; the overall excitation resultant force direction is arranged in the opposite direction to the material discharge direction of the vibrating screen, forming a stable elliptical trajectory with a vibration direction angle of 45° during operation, realizing layered, loose, and slow screening, effectively avoiding the problems of rapid accumulation of material and insufficient screening.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
