Description

Technical Field

[0001] This invention relates to the field of exciter technology, and in particular to a compact multi-axis exciter. Background Technology

[0002] With the development of industrial production, the demand for vibration equipment is increasing. The power source for vibration equipment mainly comes from the vibrator. The vibrator generates vibration and transmits the vibration to equipment such as vibrating screens to meet the working requirements.

[0003] Chinese invention patent application number CN201910322679.9 discloses a dual-axis inertial exciter, including a rotary power source, a circular gear transmission mechanism, and at least two identical eccentric mechanisms. The eccentric mechanism includes an eccentric mass block that rotates around a rotating axis. The rotary power source drives the eccentric mass to rotate around the rotating axis through the circular gear transmission mechanism. The rotational speed of each eccentric mass block is the same, and the resultant force of the eccentric force generated by all eccentric mass blocks has a zero component in the plane. Depending on the order of the driven non-circular gear pitch curve, an asymmetric inertial exciter and a reinforced inertial exciter can be realized.

[0004] However, the applicant has found that the prior art has at least the following problems:

[0005] Under cyclic loading with varying loads, bearings face high requirements and operate at high temperatures. To meet these demands, the common approach is to thicken the shaft and enlarge the bearing, which increases costs. Even with larger bearings, the high operating temperature remains a persistent issue. Furthermore, larger bearings exhibit higher linear velocity in their outer rings, leading to increased heat generation and higher temperatures under heavy loads. As customers' production lines increase capacity and equipment becomes increasingly larger, more intelligent, and more automated, simply thickening the shaft and enlarging the bearing is no longer sufficient to meet usage and functional requirements. Summary of the Invention

[0006] In view of this, the purpose of this invention is to propose a compact multi-axis vibrator to solve the problem that the existing vibrator bearings have high operating temperatures and cannot meet the requirements for use and function:

[0007] To achieve the above objectives, the present invention provides a compact multi-axis vibrator, comprising a housing on which two first main shafts and two second main shafts are mounted. The first and second main shafts have different lengths, and each of the first and second main shafts is equipped with a drive gear. The first and second main shafts are staggered, and the outermost first main shaft is externally connected to a drive motor via a coupling. The drive motor drives the drive gears to transmit power through the four shafts sequentially, and the two sets of first main shafts rotate synchronously, as do the two sets of second main shafts. Counterweight assemblies are also mounted at the ends of the first and second main shafts, each comprising a fan-shaped fixed counterweight disc with the chords of multiple fixed counterweight discs aligned. The outer circle formed by the rotation trajectory of the fixed counterweight discs does not interfere with the adjacent first and second main shafts.

[0008] Optionally, the power gear is meshed with a pinion, the pinion is fixedly connected to a drive shaft, the drive shaft is powered to connect an oil pump and a generator, lubricating oil is added inside the housing, a flow stabilizer is provided at the lower right corner of the housing, the flow stabilizer is inclined to the bottom surface of the housing, a filter is provided below the flow stabilizer, the filter is connected to an oil circulation pipeline distributed inside the housing, the oil circulation pipeline is connected to an oil pump, and a pressure oil filter and a nozzle are also provided at the top of the housing, the nozzle sprays lubricating oil onto the bearings and gears.

[0009] Optionally, oil baffles are installed on the first spindle and the second spindle respectively. The oil baffles, the skeleton oil seal, and the labyrinth seal structure are used to prevent lubricating oil from flowing out of the housing.

[0010] Optionally, the end face of the adjusting counterweight disc is integrally formed with a connecting shaft, and the connecting shaft has a receiving cavity inside. Multiple sets of counterweight cavities are arrayed inside the adjusting counterweight disc, and the multiple sets of counterweight cavities are isolated from each other. A connecting channel connects the counterweight cavities and the receiving cavity. A mounting base is fixedly installed on the inner wall of the receiving cavity. Multiple sets of blocking blocks are arrayed on the mounting base. The blocking blocks are connected to a driver to drive the blocking blocks to open and block the connecting channel. A sealed bearing is installed at the end of the connecting shaft. The sealed bearing is connected to a connecting shaft. The connecting shaft is hollow inside and connected to a cooling plate. A cooling pipe is connected inside the cooling plate. The cooling pipe is connected to a water pump for pumping water into the connecting shaft. A rotary connector is provided inside the connecting shaft. The rotary connector is electrically rotatably connected to the mounting base to supply power to the driver. The rotary connector is fixedly installed on the cooling plate.

[0011] Optionally, a conductive cable is embedded in the cooling plate, which electrically connects the generator to the rotary connector, and the generator supplies power to the drive.

[0012] Optionally, the mounting base has multiple sets of mounting slots on its periphery, and the driver is installed in the mounting slots.

[0013] Optionally, a conduit is installed in the counterweight cavity, and the conduit extends to the outside of the connecting channel until it is connected to the mounting groove. A switching pipe is provided between the mounting groove and the connecting channel. A suction port and an injection port are provided on the side wall of the switching pipe. The suction port is lower than the injection port. The injection port is connected to the receiving cavity and is used to inject water into the counterweight cavity. The suction port is connected to a suction component for extracting water from the counterweight cavity.

[0014] Optionally, the suction assembly includes a connecting rod connected to a rotary connector. The connecting rod is fixedly mounted on a cooling plate. A suction channel is provided inside the connecting rod and communicates with the cooling plate. An extraction pipe is connected inside the cooling plate and is connected to a suction pump. Multiple suction holes are provided on the side wall of the suction channel. A sealing ring is rotatably mounted on the connecting rod and fits around the multiple suction holes.

[0015] Optionally, a water-cooling pipe is embedded inside the housing, and the water-cooling pipe is connected to the extraction pipe and cooling pipe in the cooling plate.

[0016] Optionally, the multiple counterweight chambers are symmetrically arranged with a vertical line drawn downward from the axis of the first or second main shaft to which they are connected as the axis of symmetry.

[0017] The beneficial effects of this invention are:

[0018] 1. By increasing to a four-axis system, the load of the original two axes can be distributed among the four axes. The bearings can be made relatively smaller, reducing bearing heat generation. At the same time, the stability of the vibrator is increased, the service life is extended, and the production capacity of the vibrator application is increased.

[0019] 2. In existing vibrators, the gears and bearings are lubricated by immersing the gear teeth below the surface of the lubricating oil, which carries the lubricating oil away from the bottom of the housing. The oil is then transmitted to each gear through gear meshing, and the rotating gears splash the oil onto the bearings to lubricate them. However, this vibrator, by adding a lubrication system and a lubricating oil pump, can stably and continuously lubricate the power gears and bearings. Adding a filter to the lubrication system can improve the quality of the oil used to lubricate the power gears and bearings.

[0020] 3. Because the vibrator is a vibrating component, if there are external leads, there are safety hazards, and some electrical components such as vibration sensors and temperature sensors cannot be used, making it difficult to achieve intelligent operation. This vibrator has a built-in generator, which can power the electrical components used on the vibrator without external leads, making it an intelligent component and providing support for the intelligent and digital transformation of equipment.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0038] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0039] like Figures 1 to 7As shown in the figure, a specific embodiment of the present invention provides a compact multi-axis vibrator, including a housing 101. Two first main shafts 201 and two second main shafts 204 are mounted on the housing 101. The first main shafts 201 and second main shafts 204 have different lengths. Power gears 401 are respectively mounted on the first main shafts 201 and second main shafts 204. The first main shafts 201 and second main shafts 204 are staggered, and the power gears 401 on the four shafts mesh with each other in pairs. The outermost first main shaft 201 is externally connected to a universal coupling. A power motor drives a power gear 401 via a universal coupling, causing the four shafts to rotate sequentially. The two sets of first main shafts 201 rotate synchronously, and the two sets of second main shafts 204 rotate synchronously. Counterweight assemblies are also installed at the ends of the first and second main shafts 201 and 204, respectively. Each counterweight assembly includes a fan-shaped fixed counterweight disc 302 with the chords of multiple fixed counterweight discs 302 aligned. The outer circle formed by the rotation trajectory of the fixed counterweight discs 302 does not interfere with the adjacent first and second main shafts 201 and 204. Preferably, the fan-shaped fixed counterweight disc 302 is semi-circular.

[0040] At work, such as Figure 13 As shown, the first main shaft 201 located at the outermost edge is driven to rotate by a power motor. The power gear 401 on the first main shaft 201 drives the adjacent second main shaft 204 to rotate, which in turn drives the first main shaft 201 adjacent to the second main shaft 204 to rotate, and finally drives the second main shaft 204 adjacent to the first main shaft 201 to rotate. During this process, the counterweight assembly rotates, and during the rotation of the fixed counterweight disk 302, the left and right centrifugal forces of multiple fixed counterweight disks 302 cancel each other out, and the centrifugal forces in the up and down directions are in the same direction. The centrifugal force reaches its maximum when the fan-shaped surface is facing up and down. This vibrator sets up four main shafts and arranges them in an alternating manner. The distance between adjacent main shafts is just enough to accommodate the rotation of the counterweight assembly, making full use of space, with a compact structure. The four-axis structure can bear more load, reduce operating temperature, and extend the vibrator's life.

[0041] In some optional specific embodiments, such as Figures 1 to 3 as well as Figures 12 to 13As shown, the power gear 401 is meshed with a pinion 402, the pinion 402 is fixedly connected to a drive shaft 203, the drive shaft 203 is powered by an oil pump 504 and a generator, lubricating oil is added inside the housing 101, a flow stabilizer 501 is provided at the lower right corner of the housing 101, the flow stabilizer 501 is inclined to the bottom surface of the housing 101, preferably at an angle of 45°, a filter 502 is provided below the flow stabilizer 501, the filter 502 is connected to an oil circulation pipe 503 distributed inside the housing 101, the oil circulation pipe 503 is connected to the oil pump 504, the top of the housing 101 is also provided with a pressure oil filter and a nozzle 505, the nozzle 505 sprays lubricating oil onto the power gear 401, the top of the housing 101 is provided with a distribution pipe, the distribution pipe delivers lubricating oil to the bearing. During use, the housing 101 contains a certain amount of lubricating oil. When the vibrator works, the pinion 402 rotates, driving the oil pump 504 to work. The oil pump 504 pumps the lubricating oil filtered by the filter 502 through the oil circulation pipeline 503 to the nozzle 505. The nozzle 505 sprays the lubricating oil onto the gear and bearing for targeted cooling, resulting in better cooling effect. Furthermore, the lubricating oil is filtered through a specific oil circuit, making it less prone to getting dirty and improving lubrication. The generator can supply power to the signal elements on the vibrator.

[0042] In some optional specific embodiments, such as Figures 1 to 7 As shown, the first spindle 201 and the second spindle 204 are respectively equipped with an oil baffle 202, a skeleton oil seal and a labyrinth seal structure to prevent lubricating oil from flowing out of the housing 101.

[0043] In some optional specific embodiments, such as Figures 5 to 7As shown, the counterweight assembly includes an adjustable counterweight disc 301 connected to a fixed counterweight disc 302. A connecting shaft 303 is integrally formed on the end face of the adjustable counterweight disc 301. A receiving cavity 307 is provided inside the connecting shaft 303. Multiple sets of counterweight cavities 311 are arrayed inside the disc body of the adjustable counterweight disc 301. These multiple sets of counterweight cavities 311 are isolated from each other. A connecting channel 309 connects the counterweight cavities 311 and the receiving cavity 307. A mounting base 310 is fixedly installed on the inner wall of the receiving cavity 307. Multiple sets of blocking blocks 308 are arrayed on the mounting base 310. Each blocking block 308 is connected to a driver 312 for driving the blocking blocks. Block 308 opens and blocks the connecting channel 309. A sealed bearing 304 is installed at the end of the connecting shaft 303. The sealed bearing 304 is connected to the connecting shaft 305. The connecting shaft 305 is hollow inside. The connecting shaft 305 is connected to a cooling plate 102. A cooling pipe 103 is connected inside the cooling plate 102. A water pump for pumping water into the connecting shaft 305 is connected to the cooling pipe 103. A rotary connector 306 is provided inside the connecting shaft 305. The rotary connector 306 is electrically rotatably connected to the mounting base 310 for supplying power to the driver 312. The rotary connector 306 is fixedly installed on the cooling plate 102. During use, when the vibration amplitude needs to be adjusted, water is pumped into the connecting shaft 305 through the cooling pipe 103 by a water pump, and power is supplied to the driver 312 on the mounting base 310 through the rotary connector 306. The driver 312 starts, opens the connecting channel 309 connecting the counterweight chamber 311 that needs water supply, and supplies water into the counterweight chamber 311 for counterweighting. The more the water-filled counterweight chamber 311 overlaps with the fixed counterweight plate 302, the greater the overlap between the weight of the adjusting counterweight plate 301 and the counterweight area of ​​the fixed counterweight plate 302, the farther the center of gravity is from the rotation axis, and the greater the periodic centrifugal force. Conversely, when water is filled into the counterweight chamber 311 that does not overlap with the fixed counterweight plate 302, the center of gravity is closer to the rotation axis, and the periodic centrifugal force is smaller. This changes the vibration intensity. When it is necessary to reset the water-filled counterweight chamber 311, the connecting channel 309 is opened and it is inverted to pour it out.

[0044] In some optional specific embodiments, such as Figures 3 to 5 As shown, a conductive cable is embedded in the cooling plate 102, which electrically connects the generator to the rotary connector 306, and the generator supplies power to the driver 312.

[0045] In some optional specific embodiments, such as Figure 8 and Figure 9 As shown, the mounting base 310 has multiple sets of mounting slots around its periphery, and the driver 312 is installed in the mounting slots.

[0046] In some optional specific embodiments, such as Figures 8 to 11As shown, a conduit 601 is installed in the counterweight cavity 311. The conduit 601 extends to the outside of the connecting channel 309 until it is connected to the mounting groove. A switching pipe is provided between the mounting groove and the connecting channel 309. A suction port 602 and an injection port 603 are provided on the side wall of the switching pipe. The suction port 602 is lower than the injection port 603. The injection port 603 is connected to the receiving cavity 307 and is used to inject water into the counterweight cavity 311. The suction port 602 is connected to a suction component for extracting the water injected into the counterweight cavity 311. During use, when it is necessary to change the vibration amplitude, the position of the plug 308 is changed. The normal end of the plug 308 is in the connecting channel 309. When it is necessary to inject water into the counterweight cavity 311, the plug 308 moves to the mounting groove, without obstructing the filling port 603 and the suction port 602. After the filling is completed, the plug 308 continues to move to the connecting channel 309. When it is necessary to extract the water in the counterweight cavity 311, the plug 308 moves to the filling port 603 to block the filling port 603, so that the suction port 602 is connected to the counterweight cavity 311.

[0047] In some optional specific embodiments, such as Figure 10 and Figure 11 As shown, the suction assembly includes a connecting rod 604 connected to a rotary connector 306. The connecting rod 604 is fixedly mounted on a cooling plate 102. A suction channel 605 is provided inside the connecting rod 604, and the suction channel 605 communicates with the cooling plate 102. An extraction pipe 104 is connected inside the cooling plate 102, and the extraction pipe 104 is connected to a suction pump. Multiple suction holes 606 are provided on the side wall of the suction channel 605. A sealing ring 607 is rotatably mounted on the connecting rod 604. The sealing ring 607 is sleeved on the outside of the multiple suction holes 606. A flow cavity 608 is provided inside the sealing ring 607, and the flow cavity 608 communicates with the multiple suction holes 606. The flow cavity 608 is also connected to a suction tube 609, and the suction tube 609 is connected to a suction port 602. During use, adjusting the counterweight plate 301 to rotate causes the mounting base 310 to rotate, which in turn drives the sealing ring 607 to rotate. The sealing ring 607 rotates relative to the connecting rod 604, thus enabling counterweight adjustment during operation. It should be noted that the machine can also be stopped or the speed reduced for adjustment depending on the working conditions.

[0048] In some optional embodiments, a water-cooling pipe is embedded inside the housing 101, and the water-cooling pipe is connected to the extraction pipe 104 and the cooling pipe 103 in the cooling plate 102. After the water that absorbs heat in the water-cooling pipe is pumped into the counterweight chamber 311, the water is cooled more quickly because the counterweight chamber 311 is constantly rotating. After the water in the counterweight chamber 311 is extracted, it is pumped into the water-cooling pipe to cool the housing 101.

[0049] In some optional specific embodiments, the plurality of counterweight cavities 311 are symmetrically arranged with a vertical line drawn downward from the axis of the first main shaft 201 or the second main shaft 204 to which they are connected.

[0050] Working principle of the invention: The present invention provides a compact multi-axis vibrator, which, during operation, such as... Figure 13 As shown, the first main shaft 201 located at the outermost edge is driven to rotate by a power motor. The power gear 401 on the first main shaft 201 drives the adjacent second main shaft 204 to rotate, which in turn drives the first main shaft 201 adjacent to the second main shaft 204 to rotate, and finally drives the second main shaft 204 adjacent to the first main shaft 201 to rotate. During this process, the counterweight assembly rotates, and during the rotation of the fixed counterweight disk 302, the left and right centrifugal forces of multiple fixed counterweight disks 302 cancel each other out, and the centrifugal forces in the up and down directions are in the same direction. The centrifugal force reaches its maximum when the fan-shaped surface is facing up and down. This vibrator sets up four main shafts and arranges them in an alternating manner. The distance between adjacent main shafts is just enough to accommodate the rotation of the counterweight assembly, making full use of space, with a compact structure. The four-axis structure can bear more load, reduce operating temperature, and extend the vibrator's life.

[0051] Furthermore, the housing 101 contains a certain amount of lubricating oil. When the vibrator is working, the pinion 402 rotates, driving the oil pump 504 to work. The oil pump 504 pumps the lubricating oil filtered by the filter 502 through the oil circulation pipeline 503 to the nozzle 505. The nozzle 505 sprays the lubricating oil onto the gear and bearing for targeted cooling, resulting in better cooling effect. Moreover, the lubricating oil is filtered through a specific oil circuit, so it is not easy for the lubricating oil to get dirty, resulting in better lubrication effect. The generator can supply power to the signal elements on the vibrator.

[0052] When the vibration amplitude needs to be adjusted, water is pumped into the connecting shaft 305 through the cooling pipe 103 by a water pump, and power is supplied to the driver 312 on the mounting base 310 through the rotary connector 306. The driver 312 starts, opens the connecting channel 309 connecting the counterweight cavity 311 that needs water supply, and supplies water into the counterweight cavity 311 for counterweighting. The more the water-filled counterweight cavity 311 overlaps with the fixed counterweight plate 302, the greater the overlap between the weight of the adjusting counterweight plate 301 and the counterweight area of ​​the fixed counterweight plate 302, the farther the center of gravity is from the rotation axis, and the greater the periodic centrifugal force. Conversely, if water is filled into the counterweight cavity 311 that does not overlap with the fixed counterweight plate 302, the center of gravity is closer to the rotation axis, and the periodic centrifugal force is smaller, thereby changing the vibration intensity.
