Description
Technical Field
[0001] The invention relates to the technical field of reducer equipment, in particular to a right-angle planetary reducer bevel gear meshing structure. Background Art
[0002] Bevel gears are used to transmit motion and power between two intersecting axes. In general machinery, the intersection angle between the two axes of the bevel gear is equal to 90° (but it can also be different from 90°). Similar to cylindrical gears, bevel gears have pitch cones, tooth top cones, tooth root cones and base cones. The cone has a large end and a small end, and the circles corresponding to the large end are called the pitch circle (with a radius of r), tooth top circle, tooth root circle and base circle. The movement of a pair of bevel gears is equivalent to a pair of pitch cones doing pure rolling.
[0003] Among them, in order to improve the deceleration efficiency of the reducer, most of them are equipped with a large number of gears, and the deceleration is completed through the friction between the gears and the retention equipment. At the beginning of deceleration, the external force is directly transmitted to multiple gears, and the gears are affected by various retention devices, resulting in the gears needing to bear a huge force in the early stage of deceleration, which is prone to gear damage. In response to the above problems, the following solutions are proposed. Summary of the invention
[0004] In order to solve the above technical problems, the present invention provides a right-angle planetary reducer bevel gear meshing structure, comprising a fixed plate, a mounting box is fixedly connected to the side wall of the fixed plate, a fixing frame is fixedly connected to the top of the mounting box, a mounting tube is fixedly connected to the inner wall of the fixing frame, and a mounting tube is connected through the side wall of the mounting tube;
[0005] The meshing mechanism includes an input rod rotatably connected to the inner wall of the mounting tube, a bevel gear 1 is fixedly connected to the side wall of the input rod, a fixing rod is fixedly connected to the inner wall of the mounting tube, a bevel gear 2 is rotatably connected to the bottom of the fixing rod, a fixing tube is fixedly connected to the bottom of the bevel gear 2, and an adjusting assembly is fixedly connected to the inner wall of the fixing tube;
[0006] The buffer mechanism includes a rotating disk fixedly connected to an end of a fixed cylinder away from bevel gear 2, five slide grooves 1 are opened on the top of the rotating disk, and counterweights are slidably connected to the inner walls of the five slide grooves 1. The bottom of the rotating disk is fixedly connected to an output shaft, and the top of the rotating disk is fixedly connected to a control component. Before using the device, the fixed plate is installed at the required position, and the external power source is fixedly connected to the input rod. The external power forces the bevel gear 1 to rotate through the input rod, and the bevel gear 1 drives the rotating disk to rotate synchronously through the bevel gear 2 and the fixed cylinder. When the rotating disk rotates slowly, the five counterweights are tightly attached to the outer wall of the fixed cylinder, and the counterweights have an impact on the rotation. The influence of the disk's rotation speed reaches the lowest. As the speed of the rotating disk continues to increase, the centrifugal force generated by the rotating disk also increases synchronously. Excessive centrifugal force will force the counterweight to move outward along the inner wall of the slide slot one. As the counterweight moves outward, the rotation speed of the rotating disk will decrease, and the kinetic potential energy generated by the rotating disk will continue to increase. When the counterweight reaches the outermost periphery, the kinetic potential energy required for the rotation of the counterweight will also increase synchronously, and the corresponding rotation speed of the rotating disk will slow down, thereby achieving the deceleration function. Through the application of the above-mentioned components, the pressure on bevel gear one and bevel gear two in the early stage is reduced, avoiding a sudden increase in external force, which may cause the gear to shift.
[0007] Preferably, the control assembly includes a return spring 1 fixedly connected to the side wall of the counterweight block, five inclined slide grooves 1 are opened on the top of the rotating disk, and five inclined slide grooves 2 are opened on the top of the rotating disk.
[0008] Preferably, the control assembly further comprises a mounting block slidably connected to the inner wall of the first inclined slide groove, the bottom of the mounting block is rotatably connected to a roller, and the outer wall of the roller is rotatably connected to the inner wall of the second inclined slide groove.
[0009] Preferably, the control component also includes a right-angle groove opened at the top of the mounting block, an obstruction rotating plate is rotatably connected to the inner wall of the right-angle groove, and a return spring 2 is fixedly connected to the side wall of the mounting block. Utilizing the characteristic that the above-mentioned counterweight block moves outward along the inner wall of the rotating disk, a control component is arranged inside the device, wherein when the device is not running, the return spring 1 will force the counterweight block to be tightly attached to the outer wall of the fixed cylinder, and when the rotating disk starts to rotate, the centrifugal force generated by the rotating disk is relatively low, and the force of the counterweight block moving outward will be obstructed by the obstruction rotating plate and the mounting block, and as the rotation speed of the rotating disk and the centrifugal force increase, the counterweight block will push the mounting block to slide outward along the inner wall of the inclined slide groove 1 through the obstruction rotating plate, wherein there is an angle difference between the inclined slide groove 1 and the slide groove 1, presenting a Figure 5In the state of medium G, during the outward movement of the mounting block, the obstruction rotating plate will gradually separate from the outer wall of the counterweight block and release the restriction on the counterweight block. Finally, when the rotating disk speed reaches the highest, the counterweight block is completely free from the restriction of the obstruction rotating plate. Through the application of the above components, it is avoided that the rotating disk accelerates too fast in the early stage, causing the counterweight block to move outward in advance, and increasing the pressure burden on the bevel gear 1 and bevel gear 2 of the equipment in the early stage.
[0010] Preferably, one end of the return spring 2 away from the mounting block is fixedly connected to the side wall of the rotating disk, one end of the return spring 1 away from the counterweight block is fixedly connected to the inner wall of the slide groove 1, and the outer wall of the bevel gear 1 is meshed with the outer wall of the bevel gear 2. After the equipment completes its operation, the return spring 1 will release the compressed force, forcing the counterweight block to reset along the inner wall of the slide groove 1. During this process, the side wall of the counterweight block will contact the outer wall of the counterweight block, forcing the obstruction rotating plate to rotate with the vortex spring as the center. Finally, the counterweight block breaks through the restriction of the obstruction rotating plate and completes the reset, providing conditions for the subsequent operation of the equipment.
[0011] Preferably, the adjustment assembly includes five hydraulic pipes fixedly connected to the inner wall of the fixed cylinder, the inner wall of the hydraulic pipe is slidably connected to a piston plate, and the top of the piston plate is fixedly connected to a fixed bracket.
[0012] Preferably, the adjustment component also includes a mounting ring fixedly connected to the top of the five fixed brackets, the outer wall of the mounting ring is slidably connected to the inner wall of the fixed cylinder, a vortex spring is fixedly connected to the inner wall of the rotating plate to prevent the rotating plate from moving outward, and an adjustment component is arranged inside the device. When the counterweight moves outward, the distance between the counterweight and the outer wall of the fixed cylinder is expanded, and the expanded distance will drive the hydraulic telescopic tube to extend. The extended hydraulic telescopic tube will extract the liquid inside the hydraulic tube, forcing the piston plate to slide downward along the inner wall of the hydraulic tube, and the multiple sliding fixed brackets will drive The mounting rings move downward synchronously. During this process, since multiple fixed brackets are connected to the same mounting ring, the distance that the mounting rings move downward will limit the distance and speed at which multiple piston plates move downward, thereby indirectly controlling the length and speed at which the hydraulic telescopic tube and the counterweight block extend outward. Through the application of the above-mentioned components, the speed and length of the outward extension of multiple counterweight blocks can be controlled during the operation of the equipment, ensuring that the multiple counterweight blocks are at the same circular distance from the rotating disk when moving outward, thereby avoiding irregular outward movement of the counterweight blocks, causing the center of gravity of the counterweight blocks to shift, and affecting the rotation efficiency of the rotating disk.
[0013] Preferably, the adjustment component also includes a hydraulic telescopic tube connected to the side wall of the hydraulic tube, one end of the hydraulic telescopic tube away from the hydraulic tube is fixedly connected to the side wall of the counterweight block, and one end of the vortex spring away from the obstruction rotating plate is fixedly connected to the side wall of the right-angle groove. The above-mentioned installation ring is used to drive the multiple fixed brackets to move up and down. When the multiple counterweight blocks are blocked by the obstruction rotating plate, the counterweight blocks are affected by the centrifugal force and slowly move outward along the inner wall of the slide groove. In this process, the installation ring controls the distance that the multiple counterweight blocks move outward. Therefore, when the counterweight blocks move outward to squeeze the installation blocks, During movement, if a single counterweight block is unable to break through the restriction of the obstructing rotating plate during the outward movement, the remaining counterweight blocks that have broken through will transmit the centrifugal force to the piston plate through the hydraulic telescopic tube under the pull of centrifugal force, forcing the piston plate to move downward. The downward movement of the piston plate drives the mounting ring downward through the fixed bracket. At this time, the mounting ring will apply an outward thrust to the obstructed counterweight block, forcing the obstructed counterweight block to break through the corresponding obstructing rotating plate restriction. Through the application of the above components, the time difference between the counterweight blocks breaking through the obstructing rotating plate is avoided, which causes the rotation efficiency of the rotating disk to be reduced.
[0014] The present invention has the following beneficial effects:
[0015] (1) The present invention utilizes the characteristic of generating centrifugal force by rotation, and a counterweight is arranged inside the device. Before using the device, the fixed plate is installed at the desired position, and the external power source is fixedly connected to the input rod. The external power forces the bevel gear 1 to rotate through the input rod, and the bevel gear 1 drives the rotating disk to rotate synchronously through the bevel gear 2 and the fixed cylinder. When the rotating disk rotates slowly, the five counterweights are all tightly attached to the outer wall of the fixed cylinder, and the influence of the counterweights on the rotating disk speed is minimized. As the rotating disk rotates at an increasing speed, the centrifugal force generated by the rotating disk also increases synchronously. Excessive centrifugal force will force the counterweight to move outward along the inner wall of the slide groove 1. As the counterweight moves outward, the rotating disk speed will decrease, and the dynamic potential energy generated by the rotating disk will continue to increase. When the counterweight reaches the outermost periphery, the dynamic potential energy required for the rotation of the counterweight will also increase synchronously, and the corresponding rotating disk speed will slow down, thereby realizing the deceleration function. Through the application of the above-mentioned components, the pressure on the bevel gear 1 and the bevel gear 2 in the early stage is reduced, and the sudden increase of external force, which causes the gear to shift, is avoided.
[0016] (2) The present invention utilizes the characteristic that the counterweight block moves outward along the inner wall of the rotating disk, and a control component is arranged inside the device, wherein when the device is not in operation, the return spring 1 will force the counterweight block to be tightly attached to the outer wall of the fixed cylinder, and when the rotating disk starts to rotate, the centrifugal force generated by the rotating disk is relatively low, and the force of the counterweight block moving outward will be hindered by the obstruction plate and the mounting block. As the rotating disk's rotation speed and centrifugal force increase, the counterweight block will push the mounting block to slide outward along the inner wall of the inclined slide groove 1 through the obstruction plate, wherein there is an angle difference between the inclined slide groove 1 and the slide groove 1, presenting a Figure 5 In the state of medium G, during the outward movement of the mounting block, the obstruction rotating plate will gradually separate from the outer wall of the counterweight block and release the restriction on the counterweight block. Finally, when the rotating disk speed reaches the highest, the counterweight block is completely free from the restriction of the obstruction rotating plate. Through the application of the above components, it is avoided that the rotating disk accelerates too fast in the early stage, causing the counterweight block to move outward in advance, and increasing the pressure burden on the bevel gear 1 and bevel gear 2 of the equipment in the early stage.
[0017] (3) The present invention utilizes the force of the counterweight block moving outward, and an adjustment component is arranged inside the equipment. When the counterweight block moves outward, the distance between the counterweight block and the outer wall of the fixed tube is expanded, and the expanded distance will drive the hydraulic telescopic tube to extend. The extended hydraulic telescopic tube will extract the liquid inside the hydraulic tube, forcing the piston plate to slide downward along the inner wall of the hydraulic tube, and the multiple sliding fixed brackets will drive the mounting ring to move downward synchronously. In this process, since the multiple fixed brackets are connected to the same mounting ring, the downward movement distance of the mounting ring will limit the downward movement distance and speed of the multiple piston plates, thereby indirectly controlling the length and speed of the hydraulic telescopic tube and the counterweight block extending outward. Through the application of the above-mentioned components, the speed and length of the outward extension of the multiple counterweight blocks can be controlled during the operation of the equipment, ensuring that the multiple counterweight blocks are at the same circular distance as the rotating disk when moving outward, thereby avoiding irregular outward movement of the counterweight blocks, causing the center of gravity of the counterweight blocks to shift, and affecting the rotation efficiency of the rotating disk.
[0018] (4) The present invention utilizes the characteristic of the above-mentioned mounting ring to drive multiple fixed brackets to move up and down. When multiple counterweight blocks are blocked by the obstruction rotating plate, the counterweight blocks are affected by the centrifugal force and slowly move outward along the inner wall of the slide groove. In this process, since the mounting ring will control the distance that the multiple counterweight blocks move outward, when the counterweight blocks move outward to squeeze the mounting blocks to move, if a single counterweight block is difficult to break through the restriction of the obstruction rotating plate during the outward movement, the remaining counterweight blocks that have broken through will transmit the centrifugal force to the piston plate through the hydraulic telescopic tube under the pull of centrifugal force, forcing the piston plate to move downward. The downward movement of the piston plate drives the mounting ring to move downward through the fixed bracket. At this time, the mounting ring will apply an outward thrust to the obstructed counterweight block, forcing the obstructed counterweight block to break through the restriction of the corresponding obstruction rotating plate. Through the application of the above-mentioned components, it is avoided that there is a time difference between each counterweight block breaking through the obstruction rotating plate, which causes the rotation efficiency of the rotating disk to be reduced.

DETAILED DESCRIPTION
[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0031] For example, see Figure 1 - Figure 4 The present invention is a right-angle planetary reducer bevel gear meshing structure, comprising a fixing plate 1, a mounting box 11 is fixedly connected to the side wall of the fixing plate 1, a fixing frame 12 is fixedly connected to the top of the mounting box 11, a mounting tube 13 is fixedly connected to the inner wall of the fixing frame 12, and a mounting tube 14 is connected through the side wall of the mounting tube 13;
[0032] The meshing mechanism 2 includes an input rod 21 rotatably connected to the inner wall of the mounting tube 14, a bevel gear 1 22 is fixedly connected to the side wall of the input rod 21, a fixing rod 23 is fixedly connected to the inner wall of the mounting cylinder 13, a bevel gear 24 is rotatably connected to the bottom of the fixing rod 23, a fixing cylinder 25 is fixedly connected to the bottom of the bevel gear 24, and an adjustment assembly 5 is fixedly connected to the inner wall of the fixing cylinder 25;
[0033] The buffer mechanism 3 includes a rotating disk 31 fixedly connected to the end of the fixed cylinder 25 away from the bevel gear 24, five slide grooves 32 are opened on the top of the rotating disk 31, and the inner walls of the five slide grooves 32 are slidably connected with counterweights 33. The bottom of the rotating disk 31 is fixedly connected with an output shaft 34, and the top of the rotating disk 31 is fixedly connected with a control component 4. Before using the device, the fixed plate 1 is installed in the required position, and the external power source is fixedly connected to the input rod 21. The external power forces the bevel gear 1 22 to rotate through the input rod 21, and the bevel gear 1 22 drives the rotating disk 31 to rotate synchronously through the bevel gear 24 and the fixed cylinder 25. When the rotating disk 31 rotates slowly, the five counterweights 33 are all tightly attached to the outside of the fixed cylinder 25. The influence of the counterweight 33 on the rotation speed of the rotating disk 31 is minimized. As the rotation speed of the rotating disk 31 continues to increase, the centrifugal force generated by the rotating disk 31 also increases synchronously. Excessive centrifugal force will force the counterweight 33 to move outward along the inner wall of the slide groove 1 32. As the counterweight 33 moves outward, the rotation speed of the rotating disk 31 will decrease, and the kinetic potential energy generated by the rotating disk 31 will continue to increase. When the counterweight 33 reaches the outermost periphery, the kinetic potential energy required for the rotation of the counterweight 33 also increases synchronously, and the corresponding rotation speed of the rotating disk 31 will slow down, thereby realizing the deceleration function. Through the application of the above-mentioned components, the pressure on the bevel gear 1 22 and the bevel gear 2 24 in the early stage is reduced, and the sudden increase of external force, which causes the gear to shift, is avoided.
[0034] For example 2, please refer to Figure 5 - Figure 8 The present invention is a right-angle planetary reducer bevel gear meshing structure. On the basis of embodiment one, the control component 4 includes a return spring 41 fixedly connected to the side wall of the counterweight block 33, five inclined grooves 42 are opened on the top of the rotating disk 31, and five inclined grooves 43 are opened on the top of the rotating disk 31.
[0035] The control assembly 4 also includes a mounting block 44 slidably connected to the inner wall of the inclined slide groove 1 42 , a roller 45 is rotatably connected to the bottom of the mounting block 44 , and an outer wall of the roller 45 is rotatably connected to the inner wall of the inclined slide groove 2 43 .
[0036] The control assembly 4 also includes a right-angle groove 46 opened at the top of the mounting block 44, and an obstruction rotating plate 47 is rotatably connected to the inner wall of the right-angle groove 46, and a return spring 48 is fixedly connected to the side wall of the mounting block 44. Taking advantage of the characteristic that the above-mentioned counterweight block 33 moves outward along the inner wall of the rotating disk 31, a control assembly 4 is arranged inside the device, wherein when the device is not running, the return spring 41 will force the counterweight block 33 to be tightly attached to the outer wall of the fixed cylinder 25, and when the rotating disk 31 starts to rotate, the centrifugal force generated by the rotating disk 31 is relatively low, and the outward movement force of the counterweight block 33 will be obstructed by the obstruction rotating plate 47 and the mounting block 44, and as the rotation speed and centrifugal force of the rotating disk 31 increase, the counterweight block 33 will push the mounting block 44 to slide outward along the inner wall of the inclined slide groove 42 through the obstruction rotating plate 47, wherein there is an angle difference between the inclined slide groove 42 and the slide groove 32, presenting as shown in the figure. Figure 5 In the middle G state, during the outward movement of the mounting block 44, the obstruction rotating plate 47 will gradually separate from the outer wall of the counterweight block 33 and release the restriction on the counterweight block 33. Finally, when the rotating disk 31 reaches the highest speed, the counterweight block 33 is completely free from the restriction of the obstruction rotating plate 47. Through the application of the above-mentioned components, it is avoided that the rotating disk 31 accelerates too fast in the early stage, causing the counterweight block 33 to move outward in advance, thereby increasing the pressure burden on the bevel gear 1 22 and the bevel gear 2 24 of the equipment in the early stage.
[0037] One end of the return spring 48 away from the mounting block 44 is fixedly connected to the side wall of the rotating disk 31, and one end of the return spring 41 away from the counterweight 33 is fixedly connected to the inner wall of the slide groove 32. The outer wall of the bevel gear 22 is meshed with the outer wall of the bevel gear 24. After the equipment completes its operation, the return spring 41 will release the compressed force, forcing the counterweight 33 to reset along the inner wall of the slide groove 32. During this process, the side wall of the counterweight 33 will contact the outer wall of the counterweight 33, forcing the obstruction plate 47 to rotate around the vortex spring 56. Finally, the counterweight 33 breaks through the restriction of the obstruction plate 47 and completes the reset, providing conditions for the subsequent operation of the equipment.
[0038] The adjustment assembly 5 includes five hydraulic pipes 51 fixedly connected to the inner wall of the fixed cylinder 25 . The inner wall of the hydraulic pipe 51 is slidably connected to a piston plate 52 , and the top of the piston plate 52 is fixedly connected to a fixed bracket 53 .
[0039] The adjusting assembly 5 also includes a mounting ring 54 fixedly connected to the top of the five fixed brackets 53. The outer wall of the mounting ring 54 is slidably connected to the inner wall of the fixed cylinder 25. A vortex spring 56 is fixedly connected to the inner wall of the obstruction plate 47. The adjusting assembly 5 is arranged inside the device by utilizing the force of the counterweight block 33 moving outward. When the counterweight block 33 moves outward, the distance between the counterweight block 33 and the outer wall of the fixed cylinder 25 is expanded. The expanded distance will drive the hydraulic telescopic tube 55 to extend. The extended hydraulic telescopic tube 55 will extract the liquid inside the hydraulic pipe 51, forcing the piston plate 52 to slide downward along the inner wall of the hydraulic pipe 51, and the multiple sliding fixed brackets 53 will Drive the mounting ring 54 to move downward synchronously. During this process, since multiple fixed brackets 53 are connected to the same mounting ring 54, the downward movement distance of the mounting ring 54 will limit the downward movement distance and speed of multiple piston plates 52, thereby indirectly controlling the hydraulic telescopic tube 55 and the length and speed of the counterweight block 33 extending outward. Through the application of the above-mentioned components, the speed and length of the outward extension of multiple counterweight blocks 33 can be controlled during the operation of the equipment, ensuring that the multiple counterweight blocks 33 are at the same circular distance from the rotating disk 31 when moving outward, thereby avoiding irregular outward movement of the counterweight block 33, causing the center of gravity of the counterweight block 33 to shift, and affecting the rotation efficiency of the rotating disk 31.
[0040] The adjusting assembly 5 also includes a hydraulic telescopic tube 55 which is connected to the side wall of the hydraulic tube 51. The end of the hydraulic telescopic tube 55 away from the hydraulic tube 51 is fixedly connected to the side wall of the counterweight 33. The end of the vortex spring 56 away from the obstruction rotating plate 47 is fixedly connected to the side wall of the right-angle groove 46. The above-mentioned mounting ring 54 is used to drive the multiple fixed brackets 53 to move up and down. When the multiple counterweights 33 are obstructed by the obstruction rotating plate 47, the counterweights 33 are affected by the centrifugal force and slowly move outward along the inner wall of the slide groove 32. In this process, since the mounting ring 54 controls the distance that the multiple counterweights 33 move outward, when the counterweights 33 move outward to squeeze the mounting block 44, the mounting ring 54 controls the distance that the multiple counterweights 33 move outward. During movement, if a single counterweight 33 has difficulty breaking through the restriction of the obstruction rotating plate 47 during the outward movement, the remaining counterweights 33 that have broken through will transmit the centrifugal force to the piston plate 52 through the hydraulic telescopic tube 55 under the pull of centrifugal force, forcing the piston plate 52 to move downward. The downward movement of the piston plate 52 drives the mounting ring 54 to move downward through the fixed bracket 53. At this time, the mounting ring 54 will apply an outward thrust to the obstructed counterweight 33, forcing the obstructed counterweight 33 to break through the restriction of the corresponding obstruction rotating plate 47. Through the application of the above-mentioned components, the time difference between the counterweights 33 breaking through the obstruction rotating plate 47 is avoided, which causes the rotation efficiency of the rotating disk 31 to be reduced.
[0041] A specific application of this embodiment is: before use, the fixing plate 1 is installed at the desired position, and the external power source is fixedly connected to the input rod 21, the external power forces the bevel gear 1 22 to rotate through the input rod 21, and the bevel gear 1 22 drives the rotating disk 31 to rotate synchronously through the bevel gear 2 24 and the fixed cylinder 25. When the rotating disk 31 rotates slowly, the five counterweights 33 are all tightly attached to the outer wall of the fixed cylinder 25, and the influence of the counterweights 33 on the rotating speed of the rotating disk 31 is minimized. As the rotating speed of the rotating disk 31 continues to increase, the centrifugal force generated by the rotating disk 31 is also increased. As the counterweight 33 moves outward, the excessive centrifugal force will force the counterweight 33 to move outward along the inner wall of the slide groove 1 32. As the counterweight 33 moves outward, the rotation speed of the rotating disk 31 will decrease, and the dynamic potential energy generated by the rotating disk 31 will continue to increase. When the counterweight 33 reaches the outermost periphery, the dynamic potential energy required for the rotation of the counterweight 33 will also increase synchronously, and the corresponding rotation speed of the rotating disk 31 will slow down, thereby achieving the deceleration function. Through the application of the above-mentioned components, the pressure on the bevel gear 1 22 and the bevel gear 2 24 in the early stage is reduced, and the sudden increase of external force, which causes the gear to deviate, is avoided.
[0042] Taking advantage of the characteristic that the counterweight 33 moves outward along the inner wall of the rotating disk 31, a control assembly 4 is provided inside the device, wherein when the device is not in operation, the return spring 41 will force the counterweight 33 to be tightly attached to the outer wall of the fixed cylinder 25, and when the rotating disk 31 starts to rotate, the centrifugal force generated by the rotating disk 31 is relatively low, and the force of the counterweight 33 moving outward will be hindered by the obstruction plate 47 and the mounting block 44. As the rotating speed of the rotating disk 31 and the centrifugal force increase, the counterweight 33 will push the mounting block 44 to slide outward along the inner wall of the inclined slide groove 42 through the obstruction plate 47, wherein there is an angle difference between the inclined slide groove 42 and the slide groove 32, presenting as shown in FIG. Figure 5 In the middle G state, during the outward movement of the mounting block 44, the obstruction rotating plate 47 will gradually separate from the outer wall of the counterweight block 33 and release the restriction on the counterweight block 33. Finally, when the rotating disk 31 reaches the highest speed, the counterweight block 33 is completely free from the restriction of the obstruction rotating plate 47. Through the application of the above-mentioned components, it is avoided that the rotating disk 31 accelerates too fast in the early stage, causing the counterweight block 33 to move outward in advance, thereby increasing the pressure burden on the bevel gear 1 22 and the bevel gear 2 24 of the equipment in the early stage.
[0043] By utilizing the force of the counterweight 33 moving outward, an adjusting assembly 5 is arranged inside the device. When the counterweight 33 moves outward, the distance between the counterweight 33 and the outer wall of the fixed cylinder 25 is expanded. The expanded distance will drive the hydraulic telescopic tube 55 to extend. The extended hydraulic telescopic tube 55 will extract the liquid inside the hydraulic tube 51, forcing the piston plate 52 to slide downward along the inner wall of the hydraulic tube 51, and the multiple sliding fixed brackets 53 will drive the mounting ring 54 to move downward synchronously. In this process, since the multiple fixed brackets 53 are connected to the same The mounting ring 54 is installed, so the distance of the mounting ring 54 moving downward will limit the distance and speed of the multiple piston plates 52 moving downward, thereby indirectly controlling the length and speed of the hydraulic telescopic tube 55 and the counterweight block 33 extending outward. Through the application of the above components, the speed and length of the multiple counterweight blocks 33 extending outward can be controlled during the operation of the equipment, ensuring that the multiple counterweight blocks 33 are at the same circular distance from the rotating disk 31 when moving outward, avoiding the irregular outward movement of the counterweight block 33, causing the center of gravity of the counterweight block 33 to shift, and affecting the rotating disk 3 1, and utilizing the characteristic that the mounting ring 54 drives the multiple fixed brackets 53 to move up and down, when the multiple counterweight blocks 33 are blocked by the blocking rotating plate 47, the counterweight blocks 33 are affected by the centrifugal force and slowly move outward along the inner wall of the slide slot 1 32. In this process, since the mounting ring 54 controls the distance that the multiple counterweight blocks 33 move outward, when the counterweight blocks 33 move outward to squeeze the mounting block 44, if a single counterweight block 33 is difficult to break through the restriction of the blocking rotating plate 47 during the outward movement, the rest of the counterweight blocks 33 have already broken through the restriction. Under the pull of centrifugal force, the counterweight block 33 transmits the centrifugal force to the piston plate 52 through the hydraulic telescopic tube 55, forcing the piston plate 52 to move downward. The downward movement of the piston plate 52 drives the mounting ring 54 to move downward through the fixed bracket 53. At this time, the mounting ring 54 will apply an outward thrust to the obstructed counterweight block 33, forcing the obstructed counterweight block 33 to break through the restriction of the corresponding obstruction rotating plate 47. Through the application of the above-mentioned components, the time difference between the counterweight blocks 33 breaking through the obstruction rotating plate 47 is avoided, which causes the rotation efficiency of the rotating disk 31 to be reduced.
[0044] After the equipment completes operation, the reset spring 41 will release the compressed force, forcing the counterweight 33 to reset along the inner wall of the slide groove 32. During this process, the side wall of the counterweight 33 will contact the outer wall of the counterweight 33, forcing the obstruction rotating plate 47 to rotate around the vortex spring 56. Finally, the counterweight 33 breaks through the restriction of the obstruction rotating plate 47 and completes the reset, providing conditions for the subsequent operation of the equipment.
