Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, and specifically to a speed reduction device and its installation method. Background Technology

[0002] Textile machinery is a general term for mechanical equipment used to process fibers into yarns, fabrics, or other textiles. It is the core tool of the textile industry, covering all stages from raw material processing to finished product manufacturing. It is widely used in industries such as clothing, furniture, and automotive interiors. The development of textile machinery has always revolved around the evolution of fiber characteristics and process requirements. From primitive waist looms to automated equipment, its technological upgrades have directly promoted the large-scale and diversified production of the textile industry.

[0003] Textile machinery (such as spinning machines and weaving machines) typically requires high-precision, low-noise transmission systems to adapt to high-speed operation and complex processes. The speed reduction device for textile machinery is an important component, mainly used to reduce motor speed and increase output torque to meet the precise requirements of speed and tension control in textile processes. Existing speed reduction devices may lead to increased yarn breakage rate and decreased fabric uniformity due to excessive size, significant vibration, or insufficient transmission efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a speed reduction device and its installation method to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A speed reduction device and its installation method are disclosed, comprising a servo motor, a fixing block externally disposed on the servo motor, an upper protective ring and a lower protective ring fixedly connected to the side of the fixing block away from the servo motor, a hollow shaft fixedly connected to one end of the servo motor drive shaft, a positioning hole externally disposed on the fixing block, a first bearing fixedly connected to the inner circular wall of the positioning hole, the inner circular wall of the first bearing fixedly connected to the hollow shaft, a sun gear fixedly connected to the end of the hollow shaft away from the first bearing, a plurality of planetary gears meshing with the outer circular wall of the sun gear, a gear carrier meshing with the outer circular walls of the plurality of planetary gears, a third bearing disposed on the side of the gear carrier away from the hollow shaft, an output shaft fixedly connected to the inner circular wall of the inner ring of the third bearing, the output shaft being movably sleeved with the upper protective ring; a positioning component for fixing the planetary gears disposed on the inner circular wall of the gear carrier; and a snap-fit ​​component for fixing the upper and lower protective rings disposed on the top of the lower protective ring.

[0007] By adopting the above technical solution, and through the setting of the lower protective ring, when the operator prepares to install the speed reduction device, firstly, the lower protective ring is placed horizontally. Then, the operator aligns the gear carrier with the lower protective ring, fixing the gear carrier to the lower protective ring. Subsequently, the planetary gear is engaged with several support holes, and then the support holes are engaged with the planetary gear. Next, the support holes are engaged with the gear carrier, and then the second bearing is fixedly installed with the support holes. Then, the support rod is fixedly installed with the second bearing, and then the limit ring is fixedly installed with the support rod and the turntable. This completes the fixing and installation of the limit ring and the planetary gear, preventing the limit ring and planetary gear from falling off during operation. Finally, the upper protective ring is fixed to the lower protective ring, thus fixing the upper and lower protective rings together. The device is first fixedly installed with a fixed block, then with a servo motor, and finally with a drive shaft and hollow shaft. The operator then fixes the turntable and output shaft, and finally the third bearing to the turntable, completing the installation of the reduction gear. When the servo motor starts, its drive shaft rotates, causing the hollow shaft and the first bearing to rotate. Subsequently, the planetary gears rotate, and the support hole meshing with them also begins to rotate. Because the number of teeth on the planetary gears is different from that on the support hole (the number of teeth on the planetary gears is less than that on the support hole), the transmission ratio varies depending on the set tooth ratio. Therefore, the rotation period at the output end of the output shaft differs from that of the servo motor and the hollow shaft, thus slowing down the motor during operation. This allows the device to meet the different usage requirements of the textile machine under various conditions.

[0008] Preferably, the positioning component includes: a support groove, which is formed on the outer circular wall of the gear frame; several movable grooves are formed on both sides of the inner side of the support groove; a movable rod is movably sleeved on the inner circular wall of the movable groove; a support spring is movably sleeved on the outer circular wall of the movable rod; a limit block is fixedly connected to the end of the movable rod away from the movable groove; several moving blocks are provided inside the upper protective ring; a positioning block is fixedly connected to the bottom of the moving block; a moving ring is slidably connected to the outer circular wall of the positioning block; and the limit block is movably sleeved with the positioning block.

[0009] By adopting the above technical solution, and through the setting of the lower protective ring, when the operator needs to connect the gear frame and the lower protective ring, firstly, the lower protective ring is laid flat, and then the gear frame is fitted with the lower protective ring. When the gear frame and the lower protective ring are fitted, the moving block, the positioning block, and the moving ring move towards the gear frame. Subsequently, the movable rod, the support spring, and the limiting block move along the outer circular wall of the positioning block in a direction away from the positioning block. The movable rod slides inside the movable groove, and the support spring is compressed. When the limiting block passes the top of the positioning block, the force generated by the deformation of the support spring causes the limiting block to move towards the positioning block. At this time, the limiting block, the limiting spring, and the moving ring... Once the ring is engaged, the worker connects the upper protective ring to the gear carrier. At this point, the moving block, positioning block, and moving ring move towards the gear carrier. Subsequently, the movable rod, support spring, and limit block move along the outer circular wall of the positioning block away from the positioning block. The movable rod slides inside the movable groove, and the support spring is compressed. When the limit block passes the top of the positioning block, the force generated by the deformation of the support spring causes the limit block to move towards the positioning block. At this point, the limit block engages with the limit spring and the moving ring. The worker has completed the installation and positioning of the upper protective ring, gear carrier, and lower protective ring, so that the worker can subsequently install the planetary gear and support hole.

[0010] Preferably, the snap-fit ​​assembly includes a plurality of positioning discs, which are fixedly connected to the top of the gear frame. A ball cue is fixedly connected to the top of each positioning disc. A plurality of second positioning grooves are provided at the bottom of the upper protective ring. A positioning post is fixedly connected to the inner circular wall of each second positioning groove. A first positioning groove is provided at the bottom of each positioning post. A support block is fixedly connected inside the first positioning groove. The support block is made of an alloy and is elastic. A fixing groove is provided at the bottom of the support block, and the fixing groove is movably sleeved with the ball cue.

[0011] By adopting the above technical solution, and with the upper protective ring, after the worker has installed the deceleration mechanism, the upper and lower protective rings are aligned, and then the positioning post is moved towards the positioning plate. The ball rod then slides inside the fixing groove. When the top of the ball rod moves towards the positioning post, the support block is opened. When the top of the ball rod is aligned with the top of the fixing groove, the upper and lower protective rings are fixed. At this point, the installation of the deceleration device is completed, improving the worker's work efficiency.

[0012] Preferably, a fixing plate is fixedly connected to the side of the servo motor near the fixing block, and the fixing block and the fixing plate are provided with a plurality of threaded holes on the side of the fixing block near the fixing block, and screws are threaded to the inner circular wall of the threaded holes.

[0013] By adopting the above technical solution and setting a fixed plate, when the operator needs to connect the servo motor and the fixed block, the threaded hole on the outside of the fixed plate is aligned with the threaded hole on the outside of the fixed block. Then, the operator tightens the screws into the threaded holes to connect the servo motor and the fixed block. The drive shaft of the servo motor is fixedly connected to the hollow shaft, thus completing the positioning and installation of the servo motor and improving the safety of the textile machine during operation.

[0014] Preferably, the planetary gear has a support hole on the side near the gear carrier, a second bearing is fixedly connected to the inner circular wall of the support hole, a support rod is fixedly connected to the inner circular wall of the inner ring of the second bearing, and a limit ring is fixedly connected to the end of a plurality of support rods away from the second bearing.

[0015] By adopting the above technical solution, and through the set support holes, when it is necessary to fix the planetary gear and the sun gear, the support holes are first fixedly connected to the second bearing, then the second bearing is fixedly connected to the support rod, and then the support rod is fixedly connected to the limiting ring. Subsequently, the limiting ring, the turntable and the limiting rod are fixedly connected. The limiting ring and the limiting rod support and position the planetary gear and the sun gear, preventing the planetary gear and the sun gear from falling off during operation and improving the stability of the reduction device during operation.

[0016] Preferably, the end of the limiting ring away from the supporting rod has a plurality of supporting holes, the inner circular wall of the supporting holes is fixedly connected to a limiting rod, and a turntable is fixedly connected to the end of the plurality of limiting rods near the planetary gear, the turntable being fixedly connected to the third bearing.

[0017] By adopting the above technical solution, and through the setting of the limiting rod, after the worker has installed the limiting ring, the limiting rod and the limiting ring are first fixedly connected through the support hole, then the limiting rod is fixedly installed to the turntable, then the turntable is fixedly installed to the output shaft, and then the output shaft is fixedly installed to the third bearing, thus completing the installation of the output shaft. This makes the rotation frequency of the servo motor drive shaft different from the rotation frequency of the output shaft. The rotation frequency of the servo motor drive shaft is greater than the rotation frequency of the output shaft, avoiding the problem of overload and excessively high transmission efficiency of the servo motor during operation.

[0018] Preferably, the inner circular wall of the upper protective ring is provided with a plurality of limiting grooves, and a limiting spring is fixedly connected to the inner top surface of the limiting groove, and the bottom of the limiting spring is fixedly connected to the moving block.

[0019] By adopting the above technical solution, and by setting a limiting spring, when it is necessary to support and limit the moving block, firstly, the limiting groove and the limiting spring are fixedly installed, and then the limiting spring is connected to the moving block, so that the moving block can slide along the inner circular wall of the limiting groove, so that the moving block and the limiting block can be engaged, thereby improving the stability of the connection between the upper protective ring, the lower protective ring and the gear frame.

[0020] The present invention also provides a method for installing a speed reduction device, the specific steps of which are as follows:

[0021] S1: When it is necessary to fix the speed reduction device, first place the gear frame horizontally, then connect the gear frame and the lower protective ring with the positioning component, and then connect the upper protective ring and the gear frame with the positioning component to complete the installation of the upper protective ring, gear frame and lower protective ring, so that the gear frame is fixed in this position.

[0022] S2: After the gear carrier is fixed in this position, the planetary gear and the support hole are meshed and connected. Then the support hole is meshed and connected with the gear carrier. Then the second bearing and the support rod are fixed. Then the support rod, the support hole and the limit rod are fixed and installed. Then the limit rod and the gear carrier are fixed and installed, so that the limit ring and the gear carrier fit the planetary gear and the support hole together to prevent the planetary gear and the support hole from slipping during operation. Then the third bearing and the third bearing are fixed and installed, and then the third bearing and the output shaft are fixed and installed, so that when the servo motor drives the planetary gear to rotate, the support hole can play a deceleration role.

[0023] S3: When the operator moves the upper protective ring toward the sun gear, the upper and lower protective rings are fixedly installed by the snap-fit ​​assembly. Then the upper and lower protective rings are fixedly connected to the fixing block to prevent the parts of the speed reduction device from falling off during operation.

[0024] S4: The operator aligns the threaded holes on the surface of the fixed plate with the threaded holes on the outside of the fixed block, so that the drive shaft of the servo motor passes through the fixed block and is fixedly installed with the hollow shaft. Then, the servo motor and the fixed block are fixedly installed by tightening the screws, thus completing the installation of the speed reduction device, so that the operator can connect the speed reduction device to the textile machine later.

[0025] In summary, the present invention has the following main beneficial effects:

[0026] 1. The present invention uses a combination of a lower protective ring, a gear frame, a sun gear, a planetary gear, a support hole, a second bearing, a support rod, and a limiting ring. Depending on the set gear ratio, the transmission ratio is different, and the rotation period of the output end is different from the rotation period of the servo motor drive shaft. Therefore, the servo motor is decelerated during operation, which precisely matches the different speed requirements of different processes in the textile machine.

[0027] 2. The present invention uses a combination of a lower protective ring, a gear frame, a moving block, a positioning block, a moving ring, a movable rod, a support spring, and a limiting block to engage with each other, thereby enabling the workers to install the upper protective ring, the gear frame, and the lower protective ring, so that the workers can then install the planetary gear and the sun gear.

[0028] 3. The present invention uses an upper protective ring, a lower protective ring, a positioning post, a positioning plate, a ball rod, and a fixing groove to work together to make the ball rod fit against the top of the fixing groove, and the upper and lower protective rings are fixed, thus completing the installation of the deceleration device, reducing the operator's operation time and improving the operator's work efficiency.

[0029] 4. The present invention uses a fixed plate, a servo motor, a fixed block, threaded holes and screws to work together to connect the servo motor and the fixed block through the threaded holes. The drive shaft of the servo motor is fixedly connected to the hollow shaft, which completes the positioning and installation of the servo motor and improves the safety of the textile machine during operation.

[0030] 5. The present invention uses the support holes, planetary gears, sun gears, second bearings, limit rings, turntables and limit rods to work together to support and position the planetary gears and sun gears, preventing them from falling off during operation and improving the stability of the reduction device during operation.

[0042] 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.

[0043] Example: Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6A speed reduction device and its installation method include a servo motor 1, a fixing block 2 externally disposed on the servo motor 1, an upper protective ring 3 and a lower protective ring 38 fixedly connected to the side of the fixing block 2 away from the servo motor 1, a hollow shaft 4 fixedly connected to one end of the drive shaft of the servo motor 1, a positioning hole 39 externally disposed on the fixing block 2, a first bearing 5 fixedly connected to the inner circular wall of the positioning hole 39, the inner circular wall of the inner ring of the first bearing 5 fixedly connected to the hollow shaft 4, a sun gear 31 fixedly connected to the end of the hollow shaft 4 away from the first bearing 5, a plurality of planetary gears 7 meshing with the outer circular wall of the sun gear 31, a gear carrier 37 meshing with the outer circular wall of the plurality of planetary gears 7, and the gear carrier 37 away from the hollow shaft 4. A third bearing 33 is provided on one side of the planetary gear 7. An output shaft 34 is fixedly connected to the inner circular wall of the inner ring of the third bearing 33. The output shaft 34 is movably sleeved with the upper protective ring 3. A support hole 8 is provided on the side of the planetary gear 7 near the gear carrier 37. A second bearing 9 is fixedly connected to the inner circular wall of the support hole 8. A support rod 10 is fixedly connected to the inner circular wall of the inner ring of the second bearing 9. A limit ring 6 is fixedly connected to the end of several support rods 10 away from the second bearing 9. A number of support holes 11 are provided on the end of the limit ring 6 away from the support rod 10. A limit rod 12 is fixedly connected to the inner circular wall of the support hole 11. A turntable 32 is fixedly connected to the end of several limit rods 12 near the planetary gear 7. The turntable 32 is fixedly connected to the third bearing 33.

[0044] With the lower protective ring 38 in place, when the operator prepares to install the speed reduction device, the lower protective ring 38 is first placed horizontally. Then, the operator aligns the gear carrier 37 with the lower protective ring 38, fixing the gear carrier 37 in place. Next, the planetary gear 7 is meshed with several sun gears 31, followed by meshing the sun gears 317 with the gear carrier 37. This allows the second bearing 9 to be fixedly installed with the support hole 8, and then the support rod 10 to be fixedly installed with the second bearing 9. Finally, the limiting ring 6 is fixedly installed with the support rod 10 and the turntable 32, completing the fixing and installation of the limiting ring 6 and the planetary gear 7, preventing the sun gears 31 and planetary gears 7 from falling off during operation. Then, the upper protective ring 3 is fixed with the lower protective ring 38, and finally, the upper protective ring 3, the lower protective ring 38, and the fixing block 2 are fixedly installed. Then, the fixed block 2 is fixedly installed with the servo motor 1, and the drive shaft of the fixed block 2 is fixedly installed with the hollow shaft 4. Then, the operator fixes the turntable 32 and the output shaft 34, and the third bearing 33 is fixedly installed with the turntable 32, thus completing the installation of the reduction device. When the servo motor 1 starts, the drive shaft of the servo motor 1 rotates, driving the hollow shaft 4 and the first bearing 5 to rotate. Then the sun gear 31 rotates, and the sun gear 31 meshing with the sun gear 31 also starts to rotate at this time. Because the number of teeth of the planetary gear 7 and the sun gear 31 is different, the number of teeth of the planetary gear 7 is greater than that of the sun gear 31. According to the different set tooth ratio, the transmission ratio is different, and the rotation period of the output shaft 34 is different from that of the servo motor 1 and the hollow shaft 4. Therefore, the motor is decelerated during operation, which can match the usage requirements of the textile machine under different conditions.

[0045] When planetary gear 7 and sun gear 31 need to be fixed through the support hole 8, the support hole 8 is first fixedly connected to the second bearing 9, then the second bearing 9 is fixedly connected to the support rod 10, and then the support rod 10 is fixedly connected to the limiting ring 6. Subsequently, the limiting ring 6, the turntable 32 and the limiting rod 12 are fixedly connected. The limiting ring 6 and the limiting rod 12 support and position the planetary gear 7 and sun gear 31, preventing the planetary gear 7 and sun gear 31 from falling off during operation and improving the stability of the reduction device during operation.

[0046] refer to Figure 4 , Figure 7 , Figure 8 and Figure 9The inner circular wall of the gear carrier 37 is provided with a positioning component for fixing the planetary gear 7. The positioning component includes a support groove 13, which is opened on the outer circular wall of the gear carrier 37. Several movable grooves 15 are opened on both sides of the inner side of the support groove 13. A movable rod 16 is movably sleeved on the inner circular wall of the movable groove 15. A support spring 17 is movably sleeved on the outer circular wall of the movable rod 16. A limit block 18 is fixedly connected to one end of the movable rod 16 away from the movable groove 15. Several moving blocks 20 are provided inside the upper protective ring 3. A positioning block 21 is fixedly connected to the bottom of the moving block 20. A moving ring 22 is slidably connected to the outer circular wall of the positioning block 21. The limit block 18 is movably sleeved with the positioning block 21.

[0047] With the lower protective ring 38 in place, when the operator needs to connect the gear frame 37 and the lower protective ring 38, the lower protective ring 38 is first laid flat, and then the gear frame 37 is brought into contact with the lower protective ring 38. When the gear frame 37 and the lower protective ring 38 are in contact, the moving block 20, the positioning block 21, and the moving ring 22 move towards the gear frame 37. Subsequently, the movable rod 16, the support spring 17, and the limiting block 18 move along the outer circular wall of the positioning block 21 away from the positioning block 21. The movable rod 16 slides inside the movable groove 15, and the support spring 17 is compressed. When the limiting block 18 passes the top of the positioning block 21, the force generated by the deformation of the support spring 17 causes the limiting block 18 to move towards the positioning block 21. At this time, the limiting block 18 engages with the limiting spring 19 and the moving ring 22. Then, the workers connect the upper protective ring 3 and the gear frame 37. At this time, the moving block 20, the positioning block 21, and the moving ring 22 move towards the gear frame 37. Then, the movable rod 16, the support spring 17, and the limiting block 18 move along the outer circular wall of the positioning block 21 away from the positioning block 21. The movable rod 16 slides inside the movable groove 15, and the support spring 17 is compressed. When the limiting block 18 passes the top of the positioning block 21, the force generated by the deformation of the support spring 17 causes the limiting block 18 to move towards the positioning block 21. At this time, the limiting block 18 is locked with the limiting spring 19 and the moving ring 22. The workers have completed the installation and positioning of the upper protective ring 3, the gear frame 37, and the lower protective ring 38 so that the workers can subsequently install the planetary gear 7 and the support hole 8.

[0048] refer to Figure 1 , Figure 3 , Figure 7 and Figure 10The top of the lower protective ring 38 is provided with a snap-fit ​​assembly for fixing the upper protective ring 3 and the lower protective ring 38. The snap-fit ​​assembly includes several positioning discs 27, which are fixedly connected to the top of the gear frame 37. A ball stick 28 is fixedly connected to the top of the positioning discs 27. Several second positioning grooves 35 are opened at the bottom of the upper protective ring 3. A positioning post 23 is fixedly connected to the inner circular wall of the second positioning groove 35. A first positioning groove 24 is opened at the bottom of the positioning post 23. A support block 25 is fixedly connected inside the first positioning groove 24. A fixing groove 26 is opened at the bottom of the support block 25. The fixing groove 26 is movably sleeved with the ball stick 28.

[0049] With the upper protective ring 3 in place, after the worker has installed the deceleration mechanism, the worker will align the upper protective ring 3 with the lower protective ring 38, and then move the positioning post 23 toward the positioning plate 27. As a result, the ball rod 28 will slide inside the fixing groove 26. When the top of the ball rod 28 moves toward the positioning post 23, the support block 25 will be opened. When the top of the ball rod 28 is aligned with the top of the fixing groove 26, the upper protective ring 3 and the lower protective ring 38 will be fixed. At this point, the installation of the deceleration device is completed, which improves the worker's work efficiency.

[0050] refer to Figure 1 and Figure 2 A fixed plate 36 is fixedly connected to the side of the servo motor 1 near the fixed block 2. Several threaded holes 29 are opened on the side of the fixed block 2 and the fixed plate 36 near the fixed block 2. Screws 30 are threadedly connected to the inner circular wall of the threaded holes 29.

[0051] By setting the fixing plate 36, when the operator needs to connect the servo motor 1 and the fixing block 2, the threaded hole 29 on the outside of the fixing plate 36 is aligned with the threaded hole 29 on the outside of the fixing block 2. Then, the operator tightens the screw 30 into the threaded hole 29 to connect the servo motor 1 and the fixing block 2. The drive shaft of the servo motor 1 is fixedly connected to the hollow shaft 4, thus completing the installation of the servo motor 1 and improving the safety of the textile machine during operation.

[0052] refer to Figures 1-10 The present invention also provides a method for installing a speed reduction device, the specific steps of which are as follows:

[0053] S1: When it is necessary to fix the speed reduction device, first place the gear frame horizontally, then connect the gear frame and the lower protective ring with the positioning component, and then connect the upper protective ring and the gear frame with the positioning component to complete the installation of the upper protective ring, gear frame and lower protective ring, so that the gear frame is fixed in this position.

[0054] S2: After the gear carrier is fixed in this position, the planetary gear and the support hole are meshed and connected. Then the support hole is meshed and connected with the gear carrier. Then the second bearing and the support rod are fixed. Then the support rod, the support hole and the limit rod are fixed and installed. Then the limit rod and the gear carrier are fixed and installed, so that the limit ring and the gear carrier fit the planetary gear and the support hole together to prevent the planetary gear and the support hole from slipping during operation. Then the third bearing and the third bearing are fixed and installed, and then the third bearing and the output shaft are fixed and installed, so that when the servo motor drives the planetary gear to rotate, the support hole can play a deceleration role.

[0055] S3: When the operator moves the upper protective ring toward the sun gear, the upper and lower protective rings are fixedly installed by the snap-fit ​​assembly. Then the upper and lower protective rings are fixedly connected to the fixing block to prevent the parts of the speed reduction device from falling off during operation.

[0056] S4: The operator aligns the threaded holes on the surface of the fixed plate with the threaded holes on the outside of the fixed block, so that the drive shaft of the servo motor passes through the fixed block and is fixedly installed with the hollow shaft. Then, the servo motor and the fixed block are fixedly installed by tightening the screws, thus completing the installation of the speed reduction device, so that the operator can connect the speed reduction device to the textile machine later.

[0057] Working principle: Please refer to Figures 1-10As shown, with the lower protective ring 38 in place, when the operator prepares to install the speed reduction device, the lower protective ring 38 is first placed horizontally. Then, the operator aligns the gear carrier 37 with the lower protective ring 38, fixing the gear carrier 37 in place. Next, the planetary gear 7 is meshed with several sun gears 31. Then, the sun gear 317 is meshed with the gear carrier 37, thereby fixing the second bearing 9 to the support hole 8. Next, the support rod 10 is fixed to the second bearing 9, and then the limiting ring 6 is fixed to the support rod 10 and the turntable 32. This completes the fixing and installation of the limiting ring 6 and the planetary gear 7, preventing the sun gear 31 and planetary gear 7 from falling off during operation. Finally, the upper protective ring 3 is fixed to the lower protective ring 38, and then the upper protective ring 3, lower protective ring 38, and fixing block 2 are secured together. First, fix block 2 is fixedly installed to servo motor 1, and drive shaft of fixed block 2 is fixedly installed to hollow shaft 4. Then, the operator fixes turntable 32 and output shaft 34, and third bearing 33 is fixedly installed to turntable 32, thus completing the installation of the reduction gear. When servo motor 1 starts, the drive shaft of servo motor 1 rotates, driving hollow shaft 4 and first bearing 5 to rotate. Then, sun gear 31 rotates, and sun gear 31 meshing with sun gear 31 also starts to rotate. Because planetary gear 7 and sun gear 31 have different numbers of teeth, with planetary gear 7 having more teeth than sun gear 31, the transmission ratio is different depending on the set tooth ratio. The rotation period of output shaft 34 is different from that of servo motor 1 and hollow shaft 4. Therefore, the motor is slowed down during operation, which can match the usage requirements of textile machines under different conditions.

[0058] With the lower protective ring 38 in place, when the operator needs to connect the gear frame 37 and the lower protective ring 38, the lower protective ring 38 is first laid flat, and then the gear frame 37 is brought into contact with the lower protective ring 38. When the gear frame 37 and the lower protective ring 38 are in contact, the moving block 20, the positioning block 21, and the moving ring 22 move towards the gear frame 37. Subsequently, the movable rod 16, the support spring 17, and the limiting block 18 move along the outer circular wall of the positioning block 21 away from the positioning block 21. The movable rod 16 slides inside the movable groove 15, and the support spring 17 is compressed. When the limiting block 18 passes the top of the positioning block 21, the force generated by the deformation of the support spring 17 causes the limiting block 18 to move towards the positioning block 21. At this time, the limiting block 18 engages with the limiting spring 19 and the moving ring 22. Then, the workers connect the upper protective ring 3 and the gear frame 37. At this time, the moving block 20, the positioning block 21, and the moving ring 22 move towards the gear frame 37. Then, the movable rod 16, the support spring 17, and the limiting block 18 move along the outer circular wall of the positioning block 21 away from the positioning block 21. The movable rod 16 slides inside the movable groove 15, and the support spring 17 is compressed. When the limiting block 18 passes the top of the positioning block 21, the force generated by the deformation of the support spring 17 causes the limiting block 18 to move towards the positioning block 21. At this time, the limiting block 18 is locked with the limiting spring 19 and the moving ring 22. The workers have completed the installation and positioning of the upper protective ring 3, the gear frame 37, and the lower protective ring 38 so that the workers can subsequently install the planetary gear 7 and the support hole 8.

[0059] With the upper protective ring 3 in place, after the worker has installed the deceleration mechanism, the worker will align the upper protective ring 3 with the lower protective ring 38, and then move the positioning post 23 toward the positioning plate 27. As a result, the ball rod 28 will slide inside the fixing groove 26. When the top of the ball rod 28 moves toward the positioning post 23, the support block 25 will be opened. When the top of the ball rod 28 is aligned with the top of the fixing groove 26, the upper protective ring 3 and the lower protective ring 38 will be fixed. At this point, the installation of the deceleration device is completed, which improves the worker's work efficiency.

[0060] With the fixed plate 36 in place, when the operator needs to connect the servo motor 1 and the fixed block 2, the threaded hole 29 on the outside of the fixed plate 36 is aligned with the threaded hole 29 on the outside of the fixed block 2. Then, the operator tightens the screw 30 into the threaded hole 29 to connect the servo motor 1 and the fixed block 2. The drive shaft of the servo motor 1 is fixedly connected to the hollow shaft 4, thus completing the positioning and installation of the servo motor 1 and improving the safety of the textile machine during operation.

[0061] When planetary gear 7 and sun gear 31 need to be fixed through the support hole 8, the support hole 8 is first fixedly connected to the second bearing 9, then the second bearing 9 is fixedly connected to the support rod 10, and then the support rod 10 is fixedly connected to the limiting ring 6. Subsequently, the limiting ring 6, the turntable 32 and the limiting rod 12 are fixedly connected. The limiting ring 6 and the limiting rod 12 support and position the planetary gear 7 and sun gear 31, preventing the planetary gear 7 and sun gear 31 from falling off during operation and improving the stability of the reduction device during operation.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
