[0002] A gear is a mechanical element that transmits motion and power through continuous meshing of gear teeth. Since gear transmission is stable, it is used in industrial fields, transportation fields, and daily life fields, etc. Gears play an important role in various fields, providing convenience and efficiency for modern life.

A processing rod is slidably connected to the frame, and a gear shaping cutter is installed on the processing rod. A rubber storage chamber is provided on the workbench, and an elastic member is connected to the outer side wall of the storage chamber; on both sides of the elastic member on the workbench, there are support rods, and fixing rods are slidably connected to the support rods. One end of the fixing rod is connected with a first magnet, a stopper is provided at the other end of the fixing rod, a cross bar is hinged above the first magnet on the support rod, and a second magnet with the same magnetism as the first magnet is installed on the cross bar; one end of the storage chamber is connected with a feed pipe, the other end is connected with a discharge pipe, the movable end of the feed pipe is connected with a storage box, the high end of the discharge pipe is rotatably connected to the top of the support rod, and a fixing buckle is provided at the top end of the support rod.

[0004] In the above technical solution, the problems of the complex structure of the existing technical device, inapplicability to processing a small number of internal gears, and easy injury to people are solved. However, in the existing gear shaping device, a reciprocating tool is usually used to cut tooth grooves on the inner side surface of a ring. During the cutting process of the tooth grooves of the gear, a tool that needs to reciprocate vertically up and down gradually cuts the depth of the tooth grooves. The repeated reciprocating cutting action increases the processing procedures of the gear. Moreover, after the tooth grooves of the ring are processed, it is still necessary to perform the next chamfering cutting on the inner wall of the tooth grooves, increasing the cutting steps for the inner teeth of the ring and affecting the processing efficiency of the gear. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-precision gear shaping device suitable for gear processing to solve the problems raised in the above background art:

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A high-precision gear shaper suitable for gear processing, comprising a device body. A rotatable base is provided on the inner bottom surface of the device body. A ring to be processed is placed above the base. A through-type reciprocating rod is slidably connected to the surface of the device body. A rotating groove is formed on the bottom surface of the reciprocating rod. A cutter for processing the ring is rotatably connected inside the rotating groove. A plurality of sliding grooves are formed on both side surfaces of the cutter. A slider matching with each sliding groove is slidably connected inside any one of the sliding grooves. A cutting seat for processing the ring is fixedly installed on the surface of any one of the sliders. The inner side surface of the cutting seat contacts the surface of the cutter. A through-type rotating shaft is fixedly installed on the surface of the cutter. The cutter is rotatably connected to the rotating groove through the rotating shaft. A movable ring is slidably connected corresponding to the surface of the rotating shaft. A first spring is elastically connected between any one of the movable rings and the surface of the cutter. A rotating rod is provided between the cutting seat and the movable ring. A thread groove is formed corresponding to the surface of the rotating shaft. A thread screw is threadedly connected to the surface of the thread groove. The side surface of the thread screw contacts the surface of the movable ring.

[0008] By adopting the above technical solution, when the thread screw is rotated by an external wrench, at this time, the thread screw moves towards the cutter on the surface of the thread groove. After being squeezed, the movable ring moves to squeeze the first spring. At this time, the movable ring moves to drive a plurality of rotating rods to move. The plurality of rotating rods move to drive a plurality of cutting seats to move outwards, adjusting the position of the cutting seats. The rotating shaft rotates to drive the cutter to rotate at a high speed. The reciprocating rod moves downwards. The cutter rotating at a high speed cuts a groove on the inner side surface of the ring. During the process of the cutter rotating at a high speed, a plurality of cutting seats rotate at a high speed following the cutter. Since the inner side surface of the cutting seat contacts the surface of the cutter, the cutting seat rotating at a high speed chamfers and cuts the inner wall of the tooth groove. Compared with the traditional gear shaper, during the gear processing, the cutter rotating at a high speed cuts a groove on the inner side surface of the ring, and the cutter cuts at a high speed, improving the cutting speed of the tooth groove. At the same time, the cutting seat follows the cutter to move to chamfer and cut the inner wall of the tooth groove, reducing the processes during the gear processing, and thus improving the processing efficiency of the gear.

[0009] Preferably, the first spring is sleeved on the surface of the rotating shaft. One end of the first spring is fixedly connected to the surface of the cutter, and the other end of the first spring is fixedly connected to the movable ring. Both ends of the rotating rod are rotatably connected to the cutting seat and the movable ring respectively.

[0010] Preferably, a first gear is coaxially fixedly installed on the surface of the rotating shaft. The first gear is located on one side of the cutter. A second gear meshing with the first gear is rotatably connected inside the rotating groove. The second gear is located above the first gear. A micro motor is fixedly installed on the inner wall of the rotating groove. The output end of the micro motor is fixedly connected to the surface of the second gear.

[0011] By adopting the above technical solution, the first gear and the second gear mesh with each other, making the high-speed rotation of the cutting tool more stable.

[0012] Preferably, a movable frame is fixedly installed on the top surface of the reciprocating rod. One side of the movable frame is rotatably connected to a turntable. A rotating column is fixedly installed on the surface of the turntable, and the rotating column penetrates through the inside of the movable frame.

[0013] Preferably, a support seat is fixedly installed on the top surface of the device body. A first motor is fixedly installed on the top surface of the support seat, and the output end of the first motor is fixedly connected to the turntable.

[0014] By adopting the above technical solution, the first motor rotates to drive the turntable to rotate, and the turntable rotates to drive the rotating column to rotate, so that the movable frame moves up and down to drive the reciprocating rod to move up and down.

[0015] Preferably, two lubricating pipes corresponding to the processing positions of the ring are fixedly installed inside the device body, and the lubricating pipes are connected to an external oil pump through hoses.

[0016] By adopting the above technical solution, the oil pump works to extract the cutting oil fluid, and lubricates the cutting position and cools the cutting tool through the two lubricating pipes.

[0017] Preferably, a fixed seat is fixedly installed on the surface of the base table. An annular groove is formed on the surface of the fixed seat. A rotating cylinder is rotatably connected inside the annular groove. The rotating cylinder is rotatably connected to the fixed seat through the annular groove. A plurality of arc-shaped blocks are fixedly installed on the surface of the rotating cylinder. A plurality of fixing plates are fixedly installed on the top surface of the fixed seat. A penetrating guide rod is slidably connected to the surface of any one of the fixing plates. An arc-shaped clamping plate is fixedly installed on one end surface of the guide rod, and the other end of the guide rod contacts the arc-shaped block.

[0018] By adopting the above technical solution, the ring is clamped flatly between a plurality of arc-shaped clamping plates by an external clamping tool. Then the second motor rotates to drive the third gear to rotate, and the rotating teeth rotate to drive the rotating cylinder to rotate. At this time, a plurality of arc-shaped blocks rotate to squeeze the guide rod. After the guide rod is squeezed, it moves to drive a plurality of arc-shaped clamping plates to move towards the ring. The movement of the arc-shaped clamping plates drives the movement of the two clamping blocks. When the two clamping blocks move to the surface of the ring, stop the second motor. Then manually rotate the knob to make the bidirectional lead screw rotate to drive the two clamping blocks to move towards each other in the slotted groove to clamp and fix the ring. After the ring is clamped and fixed, the ring is processed again to ensure the stability during the processing of the ring. Compared with the traditional clamping device, this clamping tool is more stable after clamping the ring, and a plurality of arc-shaped blocks move simultaneously, making it more convenient and fast to clamp the ring with this clamping tool, further improving the processing speed of the gear.

[0019] Preferably, a second spring is sleeved on the surface of the guide rod. One end of the second spring is fixedly connected to the surface of the arc-shaped clamping plate, and the other end of the second spring is fixedly connected to the inner side surface of the fixed plate. The arc-shaped clamping plate is elastically connected to the fixed plate through the second spring.

[0020] By adopting the above technical solution, the second spring is used for the movement reset of the arc-shaped clamping plate.

[0021] Preferably, a slot is formed in the inner side surface of any one of the arc-shaped clamping plates. Two clamping blocks for clamping the ring are slidably connected inside the slot correspondingly. A bidirectional lead screw is rotatably connected inside any one of the slots. The two clamping blocks are threadedly connected to the surface of the bidirectional lead screw. A knob is fixedly installed on the surface of any one of the bidirectional lead screws.

[0022] By adopting the above technical solution, manually rotate the knob, so that the bidirectional lead screw rotates to drive the two clamping blocks to move towards each other in the slot to clamp and fix the ring.

[0023] Preferably, a rotating tooth is fixedly installed on the surface of the rotating cylinder. A mounting plate is fixedly installed on the surface of the base table. A second motor is fixedly installed on the bottom surface of the mounting plate. An output end of the second motor is fixedly installed with a third gear meshing with the rotating tooth.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1) When the high-precision gear shaping device applicable to gear processing is in use, rotate the threaded wire with an external wrench. At this time, the threaded wire moves towards the tool along the surface of the thread groove. After being squeezed, the movable ring moves to squeeze the first spring. At this time, the movable ring moves to drive a plurality of rotating rods to move. The plurality of rotating rods move to drive a plurality of cutting seats to move outwards to adjust the positions of the cutting seats. The rotating shaft rotates to drive the tool to rotate at a high speed. The reciprocating rod moves downwards. The tool rotating at a high speed cuts a groove on the inner side surface of the ring. During the process of the tool rotating at a high speed, the plurality of cutting seats rotate at a high speed following the tool. Since the inner side surface of the cutting seat contacts the surface of the tool, the cutting seat rotating at a high speed chamfers and cuts the inner wall of the tooth groove. Compared with the traditional gear shaping device, during the gear processing, the tool rotating at a high speed cuts a groove on the inner side surface of the ring, and the tool rotates and cuts at a high speed, which improves the cutting speed of the tooth groove. At the same time, the cutting seat follows the tool to move to chamfer and cut the inner wall of the tooth groove, reducing the processes in the gear processing, and thus improving the gear processing efficiency.

[0026] 2) When the high-precision gear shaping device applicable to gear processing is in use, an external clamping tool clamps the ring and places it flatly between multiple arc-shaped clamping plates. Then, the second motor rotates to drive the third gear to rotate, and the rotating gear rotates to drive the rotating cylinder to rotate. At this time, multiple arc-shaped blocks rotate to squeeze the guide rod. After the guide rod is squeezed, it moves to drive multiple arc-shaped clamping plates to move towards the ring. The movement of the arc-shaped clamping plates drives the movement of two clamping blocks. When the two clamping blocks move to the surface of the ring, stop the second motor. Then, manually rotate the knob to make the bidirectional lead screw rotate to drive the two clamping blocks to move towards each other in the slots to clamp and fix the ring. After the ring is clamped and fixed, the ring is processed through the processing steps in the embodiment to ensure the stability during the ring processing. Compared with the traditional clamping device, this clamping tool is more stable after clamping the ring, and multiple arc-shaped blocks move simultaneously, making it more convenient and fast to clamp the ring with the clamping tool, further improving the gear processing speed.

[0040] Example 1: Please refer to Figure 1 - Figure 12, A high-precision gear shaping device applicable to gear processing, comprising a device body 1. The device body 1 is a device for gear production and processing. A rotatable table 2 is provided on the inner bottom surface of the device body 1. A driving device is arranged inside the device body 1, and the output end of the driving device is fixedly connected to the bottom surface of the table 2. The driving device is a conventional driving device in the prior art, and the rotation angle of the driving device is controllable to achieve orderly cutting of the tooth grooves on the inner side of the ring 3. The to-be-processed ring 3 is placed above the table 2. A through-type reciprocating rod 4 is slidably connected to the surface of the device body 1. A rotating groove 18 is formed on the bottom surface of the reciprocating rod 4, and a cutter 5 for processing the ring 3 is rotatably connected inside the rotating groove 18. The cutter 5 is a cutter 5 that rotates at a high speed. Compared with the traditional reciprocating cutting tool, the cutter 5 that rotates at a high speed makes the cutting of the tooth grooves faster. A plurality of sliding grooves 6 are formed on both side surfaces of the cutter 5, and a sliding block 7 matching with each sliding groove 6 is slidably connected inside any one of the sliding grooves 6. A cutting seat 8 for processing the ring 3 is fixedly installed on the surface of any one of the sliding blocks 7. The cutting seat 8 rotates with the cutter 5 to perform chamfering cutting on the inner wall of the tooth groove. The inner side surface of the cutting seat 8 is in contact with the surface of the cutter 5. A through-type rotating shaft 9 is fixedly installed on the surface of the cutter 5, and the cutter 5 is rotatably connected to the rotating groove 18 through the rotating shaft 9. A movable ring 10 is slidably connected to the surface of the rotating shaft 9 correspondingly. A first spring 11 is elastically connected between any one of the movable rings 10 and the surface of the cutter 5. The first spring 11 is used for the movement reset of the movable ring 10. A rotating rod 12 is arranged between the cutting seat 8 and the movable ring 10. A threaded groove 13 is formed on the surface of the rotating shaft 9 correspondingly. A threaded wire 14 is threadedly connected to the surface of the threaded groove 13. The side surface of the threaded wire 14 is in contact with the surface of the movable ring 10. By turning the threaded wire 14 with an external wrench, at this time, the threaded wire 14 moves towards the cutter 5 on the surface of the threaded groove 13. After the movable ring 10 is squeezed, it moves to squeeze the first spring 11. At this time, the movable ring 10 moves to drive a plurality of rotating rods 12 to move, and a plurality of rotating rods 12 move to drive a plurality of cutting seats 8 to move outwards to adjust the position of the cutting seats 8. The rotating shaft 9 rotates to drive the cutter 5 to rotate at a high speed, and the reciprocating rod 4 moves downwards. The cutter 5 that rotates at a high speed cuts the inner side surface of the ring 3. During the process of the cutter 5 rotating at a high speed, a plurality of cutting seats 8 rotate at a high speed following the cutter 5. Since the inner side surface of the cutting seat 8 is in contact with the surface of the cutter 5, the cutting seat 8 rotating at a high speed performs chamfering cutting on the inner wall of the tooth groove. Compared with the traditional gear shaping device, during the gear processing, the cutter 5 that rotates at a high speed cuts the inner side surface of the ring 3, and the cutter 5 rotates at a high speed for cutting, which improves the cutting speed of the tooth groove. At the same time, the cutting seat 8 follows the cutter 5 to move to perform chamfering cutting on the inner wall of the tooth groove, reducing the processes during the gear processing, and thus improving the gear processing efficiency.

[0041] The first spring 11 is sleeved on the surface of the rotating shaft 9. One end of the first spring 11 is fixedly connected to the surface of the cutting tool 5, and the other end of the first spring 11 is fixedly connected to the movable ring 10. Both ends of the rotating rod 12 are rotatably connected to the cutting seat 8 and the movable ring 10 respectively.

[0042] A first gear 15 is coaxially and fixedly installed on the surface of the rotating shaft 9. The first gear 15 is located on one side of the cutting tool 5. A second gear 16 meshing with the first gear 15 is rotatably connected inside the rotating groove 18. The second gear 16 is located above the first gear 15. A micro motor 17 is fixedly installed on the inner wall of the rotating groove 18. The micro motor 17 is a conventional electric motor in the prior art. The output end of the micro motor 17 is fixedly connected to the surface of the second gear 16. The first gear 15 and the second gear 16 mesh with each other, making the high-speed rotation of the cutting tool 5 more stable.

[0043] A movable frame 19 is fixedly installed on the top surface of the reciprocating rod 4. A turntable 21 is rotatably connected to one side of the movable frame 19. A rotating column 20 is fixedly installed on the surface of the turntable 21. The rotating column 20 penetrates through the inside of the movable frame 19.

[0044] A support seat 22 is fixedly installed on the top surface of the device body 1. A first motor 23 is fixedly installed on the top surface of the support seat 22. The first motor 23 is a conventional electric motor in the prior art. The rotation speed of the first motor 23 is controllable. The output end of the first motor 23 is fixedly connected to the turntable 21. The rotation of the first motor 23 drives the turntable 21 to rotate, and the rotation of the turntable 21 drives the rotating column 20 to rotate, so that the movable frame 19 moves up and down to drive the reciprocating rod 4 to move up and down.

[0045] Two lubricating pipes 24 corresponding to the processing positions of the ring 3 are fixedly installed inside the device body 1. The lubricating pipes 24 are connected to an external oil pump through hoses. The oil pump is a conventional oil pump in the prior art. The oil pump works to extract cutting oil fluid, and lubricates the cutting position and cools the cutting tool 5 through the two lubricating pipes 24.

[0046] Usage steps of the present invention: When the high-precision gear shaping device applicable to gear processing is in use, first, fix the to-be-processed ring 3 above the base 2, and then rotate the threaded screw 14 with an external wrench. At this time, the threaded screw 14 moves towards the tool 5 on the surface of the threaded groove 13. After being squeezed, the movable ring 10 moves to squeeze the first spring 11. At this time, the movable ring 10 moves to drive multiple rotating rods 12 to move. The multiple rotating rods 12 move to drive multiple cutting seats 8 to move outwards. At this time, the cutting seats 8 move to drive the sliders 7 to move inside the sliding grooves 6. The multiple cutting seats 8 move along the surface of the tool 5. When the position adjustment of the cutting seats 8 is completed, the micro motor 17 rotates to drive the second gear 16 to rotate. The second gear 16 rotates to drive the first gear 15 to rotate. At this time, the rotating shaft 9 rotates to drive the tool 5 to rotate at a high speed. The oil pump works to extract the cutting fluid, and lubricate the cutting position and cool the tool 5 through two lubricating pipes 24. Then, the first motor 23 rotates to drive the turntable 21 to rotate (the rotation speed of the first motor 23 is controllable). The turntable 21 rotates to drive the rotating column 20 to rotate, so that the movable frame 19 moves up and down to drive the reciprocating rod 4 to move up and down. The reciprocating rod 4 moves downwards to drive the tool 5 to move downwards to contact the surface of the to-be-processed ring 3. As the reciprocating rod 4 continues to move downwards, at this time, the tool 5 rotating at a high speed cuts a groove on the inner side surface of the ring 3. During the process of the tool 5 rotating at a high speed, the multiple cutting seats 8 rotate at a high speed following the tool 5. Since the inner side surface of the cutting seat 8 contacts the surface of the tool 5, during the process of the tool 5 cutting the tooth groove of the ring 3, the cutting seat 8 rotating at a high speed chamfers the inner wall of the tooth groove. When one tooth groove of the ring 3 is processed, at this time, the reciprocating rod 4 moves upwards to drive the tool 5 to move upwards, and then the driving device drives the base 2 to move (the rotation angle of the driving device is controllable). The reciprocating rod 4 moves downwards to drive the tool 5 to continue processing the next tooth groove. In this solution, the threaded screw 14 is rotated with an external wrench. At this time, the threaded screw 14 moves towards the tool 5 on the surface of the threaded groove 13. After being squeezed, the movable ring 10 moves to squeeze the first spring 11. At this time, the movable ring 10 moves to drive multiple rotating rods 12 to move. The multiple rotating rods 12 move to drive multiple cutting seats 8 to move outwards to adjust the position of the cutting seats 8. The rotating shaft 9 rotates to drive the tool 5 to rotate at a high speed. The reciprocating rod 4 moves downwards. The tool 5 rotating at a high speed cuts a groove on the inner side surface of the ring 3. During the process of the tool 5 rotating at a high speed, the multiple cutting seats 8 rotate at a high speed following the tool 5. Since the inner side surface of the cutting seat 8 contacts the surface of the tool 5, the cutting seat 8 rotating at a high speed chamfers the inner wall of the tooth groove. Compared with the traditional gear shaping device, during the gear processing, the tool 5 rotating at a high speed cuts a groove on the inner side surface of the ring 3, and the tool 5 rotates and cuts at a high speed, which improves the cutting speed of the tooth groove. At the same time, the cutting seat 8 follows the tool 5 to move to chamfer the inner wall of the tooth groove, reducing the processes during the gear processing, and thus improving the gear processing efficiency.

[0047] Example 2: Please refer toFigure 1 - Figure 12 Differing from the basis of Embodiment 1, a fixed seat 25 is fixedly installed on the surface of the base 2. An annular groove 26 is formed on the surface of the fixed seat 25. A rotating cylinder 27 is rotatably connected inside the annular groove 26. The rotating cylinder 27 is rotatably connected to the fixed seat 25 through the annular groove 26. A plurality of arc-shaped blocks 28 are fixedly installed on the surface of the rotating cylinder 27. The plurality of arc-shaped blocks 28 move simultaneously, making it more convenient and rapid for the clamping tool to clamp the ring 3. A plurality of fixing plates 29 are fixedly installed on the top surface of the fixed seat 25. A through guide rod 30 is slidably connected to the surface of any one of the fixing plates 29. The guide rod 30 is used to guide the movement of the arc-shaped clamping plate 31. An arc-shaped clamping plate 31 is fixedly installed on one end surface of the guide rod 30. The other end of the guide rod 30 contacts the arc-shaped block 28. The ring 3 is clamped flatly between a plurality of arc-shaped clamping plates 31 by an external clamping tool. Then, the second motor 40 rotates to drive the third gear 38 to rotate, and the rotating teeth 37 rotate to drive the rotating cylinder 27 to rotate. At this time, the plurality of arc-shaped blocks 28 rotate and squeeze the guide rod 30. After being squeezed, the guide rod 30 moves to drive a plurality of arc-shaped clamping plates 31 to move towards the ring 3. The movement of the arc-shaped clamping plate 31 drives the movement of the two clamping blocks 34. When the two clamping blocks 34 move to the surface of the ring 3, the second motor 40 stops working. Then, the knob 36 is manually rotated to make the bidirectional lead screw 35 rotate to drive the two clamping blocks 34 to move towards each other in the slot 33 to clamp and fix the ring 3. After the ring 3 is clamped and fixed, the ring 3 is processed, ensuring the stability during the processing of the ring 3. Compared with the traditional clamping device, the clamping tool is more stable after clamping the ring 3, and the plurality of arc-shaped blocks 28 move simultaneously, making it more convenient and rapid for the clamping tool to clamp the ring 3, further improving the processing speed of the gear.

[0048] A second spring 32 is sleeved on the surface of the guide rod 30. One end of the second spring 32 is fixedly connected to the surface of the arc-shaped clamping plate 31, and the other end of the second spring 32 is fixedly connected to the inner side surface of the fixing plate 29. The arc-shaped clamping plate 31 is elastically connected to the fixing plate 29 through the second spring 32. The second spring 32 is used for the movement reset of the arc-shaped clamping plate 31.

[0049] A slot 33 is formed on the inner side surface of any one of the arc-shaped clamping plates 31. Two clamping blocks 34 for clamping the ring 3 are slidably connected inside the slot 33 correspondingly. A bidirectional lead screw 35 is rotatably connected inside any one of the slots 33. The two clamping blocks 34 are threadedly connected to the surface of the bidirectional lead screw 35. A knob 36 is fixedly installed on the surface of any one of the bidirectional lead screws 35. The knob 36 is manually rotated to make the bidirectional lead screw 35 rotate to drive the two clamping blocks 34 to move towards each other in the slot 33 to clamp and fix the ring 3.

[0050] The surface of the rotary cylinder 27 is fixedly installed with rotary teeth 37. The surface of the base 2 is fixedly installed with a mounting plate 39. The bottom surface of the mounting plate 39 is fixedly installed with a second motor 40. The output end of the second motor 40 is fixedly installed with a third gear 38 meshing with the rotary teeth 37. The second motor 40 is a conventional forward and reverse motor in the prior art.

[0051] The usage steps of the present invention: When the high-precision gear shaping device applicable to gear processing is in use, before processing the ring 3, it is necessary to fix the ring 3 to be processed. In the initial state, the distance between the two clamping blocks 34 is greater than the thickness of the ring 3. The ring 3 is clamped by an external clamping tool and placed flat between multiple arc-shaped clamping plates 31. Then, the second motor 40 rotates to drive the third gear 38 to rotate, and the rotary teeth 37 rotate to drive the rotary cylinder 27 to rotate. At this time, multiple arc-shaped blocks 28 rotate to squeeze the guide rod 30. After being squeezed, the guide rod 30 moves to drive multiple arc-shaped clamping plates 31 to move towards the ring 3. The movement of the arc-shaped clamping plates 31 drives the two clamping blocks 34 to move. When the two clamping blocks 34 move to the surface of the ring 3, stop the second motor 40 from working. Then, manually rotate the knob 36 to make the bidirectional lead screw 35 rotate to drive the two clamping blocks 34 to move towards each other in the slot 33 to clamp and fix the ring 3. After the ring 3 is clamped and fixed, the ring 3 is processed through the processing steps in Embodiment 1 to ensure the stability during the processing of the ring 3.
