[0014] The present invention provides a planetary reducer with a noise reduction structure. It has the following beneficial effects:

[0015] (1) For the planetary reducer with a noise reduction structure, by first manually pulling the fixed frame to move away from the deceleration bracket, the fixed frame moves away from the deceleration bracket and disengages from the contact with the U-shaped plate and releases the limit on the U-shaped plate. The fixed frame can prevent the loosening of the noise reduction frame caused by accidental touch, which can ensure that the reducer body can maintain its noise reduction performance during operation, thereby effectively reducing the noise caused by mechanical vibration and further creating a quieter working environment. By the upward movement of the U-shaped plate to reset and contact the inner wall of the installation groove to complete the installation of the noise reduction frame. If the noise reduction frame is damaged or its performance deteriorates, the noise reduction frame with a quick-disassembly design can be easily disassembled for replacement or repair without overall disassembly of the reducer, thereby reducing the difficulty and complexity of maintaining the reducer body.

[0016] (2) In the planetary speed reducer with a noise reduction structure, the liquid inside the load-bearing frame can only move slowly through the speed reduction holes, causing the load-bearing plate and the load-bearing rod to move slowly. The slow movement of the load-bearing rod causes the stabilizing plate to move slowly. The slow movement can help the stabilizing plate achieve higher positioning accuracy during adjustment, ensuring the tight fit between the stabilizing plate and the noise reduction frame, thereby enhancing the overall structural stability. When the stabilizing plate moves towards the support rod and contacts the inner wall of the noise reduction groove, it can assist in fixing the noise reduction frame. Through the contact between the stabilizing plate and the inner wall of the noise reduction groove, the overall stability of the noise reduction frame can be effectively enhanced, preventing it from loosening due to vibration or external forces during operation, and further maintaining its noise reduction effect.

[0017] (3) In the planetary speed reducer with a noise reduction structure, when the limiting plate moves towards the button, it drives the limiting rod to move. The movement of the limiting rod contacts the inner wall of the protection groove and limits the button. The button cannot be pressed due to the limitation of the limiting rod. When the noise reduction frame is disassembled, the button cannot be pressed, thus avoiding the risk of accidental startup, preventing potential injuries or equipment damage, and during inspection or maintenance, keeping the equipment stationary can improve the efficiency and safety of the maintenance work.

Detailed implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-8 , an embodiment of the present invention is: a planetary reducer with a noise reduction structure, including a deceleration bracket 1, and further including an assembly device. Among them, a reducer body 2 is arranged on the top of the deceleration bracket 1, a noise reduction frame 3 is arranged on the circumferential surface of the reducer body 2, a noise reduction groove 31 is opened on the circumferential surface of the noise reduction frame 3, an installation groove 4 is opened at the bottom of the noise reduction frame 3, a button 148 is fixedly installed on the surface of the deceleration bracket 1, a motor 32 is arranged on the front side of the reducer body 2, and the button 148 is electrically connected to the motor 32. Among them, the assembly device includes a support hole 5, a support rod 6, a U-shaped plate 7, a support spring 8, a fixed rod 9, a fixed plate 10 and a fixed frame 11. The support hole 5 is opened on the left side of the deceleration bracket 1, the support rod 6 is fixedly installed on the inner wall of the support hole 5, the U-shaped plate 7 is slidably installed on the circumferential surface of the support rod 6, the support spring 8 is arranged between the support rod 6 and the U-shaped plate 7, the fixed rod 9 is fixedly installed on the rear side of the deceleration bracket 1, the fixed plate 10 is fixedly installed on the rear side of the fixed rod 9, and the fixed frame 11 is slidably installed on the circumferential surface of the fixed rod 9. By preventing the noise reduction frame 3 from loosening caused by accidental touch through the fixed frame 11, it can ensure that the reducer body 2 can maintain its noise reduction performance during operation, thereby effectively reducing the noise caused by mechanical vibration.

[0029] A fixed spring 12 is arranged between the fixed rod 9 and the fixed frame 11, and the fixed spring 12 can drive the fixed frame 11 to reset. The bottom of the U-shaped plate 7 is set as an inclined surface, and the U-shaped plate 7 contacts the inner wall of the support hole 5.

[0030] The U-shaped plate 7 contacts the fixed frame 11 and the inner wall of the installation groove 4. One side of the fixed frame 11 close to the U-shaped plate 7 is set as an inclined surface. The U-shaped plate 7 moves upward to reset and contacts the inner wall of the installation groove 4, completing the installation of the noise reduction frame 3. The noise reduction frame 3 with a quick-release design can be easily disassembled for replacement or repair without disassembling the entire reducer body 2.

[0031] During the operation of this embodiment: When the noise reduction frame 3 needs to be disassembled, first manually pull the fixed frame 11 to move away from the reduction support 1. The fixed frame 11 moving away from the reduction support 1 pulls the fixed spring 12, and the fixed spring 12 deforms and stores energy under the pull of the fixed frame 11. At the same time, the fixed frame 11 moving away from the reduction support 1 disengages from the contact with the U-shaped plate 7 and releases the limit on the U-shaped plate 7. After the limit on the U-shaped plate 7 is released, manually press the U-shaped plate 7 to move downward. The U-shaped plate 7 moving downward squeezes the support spring 8, and the support spring 8 deforms and stores energy under the squeeze of the U-shaped plate 7. At the same time, the U-shaped plate 7 moving downward disengages from the contact with the installation groove 4 and releases the limit on the noise reduction frame 3. After the limit on the noise reduction frame 3 is released, manually pull the noise reduction frame 3 to move away from the fixed plate 10 and disengage from the contact with the reducer body 2. When installing the noise reduction frame 3, also first manually pull the fixed frame 11 to move away from the reduction support 1. The fixed frame 11 moving away from the reduction support 1 pulls the fixed spring 12, and the fixed spring 12 deforms and stores energy under the pull of the fixed frame 11. At the same time, the fixed frame 11 moving away from the reduction support 1 disengages from the contact with the U-shaped plate 7 and releases the limit on the U-shaped plate 7. After the limit on the U-shaped plate 7 is released, manually press the U-shaped plate 7 to move downward. The U-shaped plate 7 moving downward squeezes the support spring 8, and the support spring 8 deforms and stores energy under the squeeze of the U-shaped plate 7. At the same time, manually push the noise reduction frame 3 to move closer to the fixed plate 10 and contact the reducer body 2. The noise reduction frame 3 moving closer to the fixed plate 10 aligns the installation groove 4 with the U-shaped plate 7. After the installation groove 4 is aligned with the U-shaped plate 7, release the U-shaped plate 7 so that the U-shaped plate 7 moves upward to reset under the elastic force of the support spring 8. The U-shaped plate 7 moving upward to reset contacts the inner wall of the installation groove 4 and completes the installation of the noise reduction frame 3. After the noise reduction frame 3 is firmly installed, manually press the button 148 to drive the motor 32 to rotate. The rotation of the motor 32 drives the reducer body 2 to operate and decelerate the motor 32.

[0032] Please refer to Figures 1-8, on the basis of the above embodiments, in another embodiment of the present invention, an auxiliary device for preventing the noise reduction frame 3 from shifting is provided on the surface of the deceleration bracket 1, and a detection device is provided on the surface of the deceleration bracket 1. The auxiliary device includes a load-bearing frame 131, a load-bearing plate 132, a linkage plate 133, a load-bearing rod 134, a stabilizing plate 135, a stabilizing hole 136, and a deceleration hole 137. The load-bearing frame 131 is fixedly installed on the right side of the deceleration bracket 1. The load-bearing plate 132 is slidably installed on the inner wall of the load-bearing frame 131. The load-bearing rod 134 is fixedly installed on the right side of the load-bearing plate 132. The stabilizing plate 135 is fixedly installed on the right side of the load-bearing rod 134. The stabilizing hole 136 is opened on the right side of the stabilizing plate 135. The linkage plate 133 is fixedly installed on the inner wall of the stabilizing hole 136. The deceleration hole 137 is opened on the right side of the load-bearing plate 132. By the contact between the stabilizing plate 135 and the inner wall of the noise reduction groove 31, the overall stability of the noise reduction frame 3 can be effectively enhanced, and the slow movement can help the stabilizing plate 135 achieve higher positioning accuracy during the adjustment process.

[0033] A load-bearing spring 138 is provided between the load-bearing frame 131 and the load-bearing plate 132. The load-bearing spring 138 can drive the load-bearing plate 132 to reset. There is liquid inside the load-bearing frame 131. The stabilizing plate 135 contacts the inner wall of the noise reduction groove 31. There are two groups of load-bearing frame 131, load-bearing plate 132, linkage plate 133, load-bearing rod 134, stabilizing plate 135, stabilizing hole 136, and deceleration hole 137. And in the other group, the load-bearing frame 131 is fixedly installed on the left side of the deceleration bracket 1, the load-bearing rod 134 is fixedly installed on the left side of the load-bearing plate 132, the stabilizing plate 135 is fixedly installed on the left side of the load-bearing rod 134, and the stabilizing hole 136 is opened on the left side of the stabilizing plate 135.

[0034] The detection device includes a detection tube 141, a detection plate 142, a detection rod 143, a square plate 144, a limiting plate 146, a limiting rod 147, and a protection groove 149. The detection tube 141 fixedly penetrates the left and right walls of the deceleration bracket 1. The detection plate 142 is slidably installed on the inner wall of the detection tube 141. The detection rod 143 is fixedly installed on the left side of the detection plate 142. The square plate 144 is fixedly installed on the left side of the detection rod 143. The limiting plate 146 is fixedly installed on the inner wall of the detection tube 141. The limiting rod 147 is fixedly installed on the left side of the limiting plate 146. The protection groove 149 is opened on the circumferential surface of the button 148. When the noise reduction frame 3 is disassembled, the button 148 cannot be pressed, thus avoiding the risk of accidental startup and preventing potential injuries or equipment damage.

[0035] A detection spring 145 is provided between the detection tube 141 and the detection plate 142. The detection spring 145 can drive the detection plate 142 to reset. A steel wire rope is provided between the detection plate 142 and the limiting plate 146. The square plate 144 contacts the stabilizing plate 135.

[0036] A first spring is arranged between the limit plate 146 and the detection tube 141. One end of the first spring is arranged on the inner wall of the detection tube 141, and the other end is arranged on the right side of the limit plate 146. The first spring can drive the limit plate 146 to reset. The left side of the limit rod 147 is provided with an inclined surface. A connecting ring is arranged between the detection rod 143 and the square plate 144. The connecting ring can improve the connection tightness between the detection rod 143 and the square plate 144. The elastic coefficient of the detection spring 145 is greater than that of the first spring.

[0037] When this embodiment works: The U-shaped plate 7 moves downward to contact the linkage plate 133 and extrude the linkage plate 133. The linkage plate 133 moves away from the support rod 6 under the extrusion of the U-shaped plate 7. The movement of the linkage plate 133 away from the support rod 6 drives the stable plate 135 to move away from the contact with the noise reduction groove 31, facilitating the removal of the noise reduction frame 3. At the same time, the movement of the stable plate 135 away from the support rod 6 drives the load-bearing rod 134 to move. The movement of the load-bearing rod 134 drives the load-bearing plate 132 to move. The movement of the load-bearing plate 132 pulls the load-bearing spring 138. The load-bearing spring 138 deforms and stores energy under the pull of the load-bearing plate 132. At the same time, the movement of the load-bearing plate 132 squeezes the liquid inside the load-bearing frame 131. The liquid inside the load-bearing frame 131 can only move slowly through the deceleration holes 137 under the extrusion of the load-bearing plate 132. The fact that the liquid inside the load-bearing frame 131 can only move slowly through the deceleration holes 137 causes the load-bearing plate 132 and the load-bearing rod 134 to move slowly. The slow movement of the load-bearing rod 134 causes the stable plate 135 to move slowly. When the U-shaped plate 7 moves upward to reset, the U-shaped plate 7 moves upward to separate from the linkage plate 133, causing the load-bearing plate 132 to move toward the support rod 6 under the elastic force of the load-bearing spring 138. The movement of the load-bearing plate 132 toward the support rod 6 drives the load-bearing rod 134 and the stable plate 135 to move. The movement of the stable plate 135 toward the support rod 6 contacts the inner wall of the noise reduction groove 31 and assists in fixing the noise reduction frame 3.

[0038] The linkage plate 133 moves away from the support rod 6 to drive the stable plate 135 to move. The stable plate 135 moves to contact the square plate 144 and extrude the square plate 144. The square plate 144 moves away from the support rod 6 under the extrusion of the stable plate 135. The square plate 144 moving away from the support rod 6 drives the detection rod 143 to move. The detection rod 143 moving drives the detection plate 142 to move. The detection plate 142 moving pulls the detection spring 145. The detection spring 145 deforms and stores energy under the pull of the detection plate 142. At the same time, the detection plate 142 moving away from the support rod 6 drives the steel wire rope to move. The movement of the steel wire rope causes the limit plate 146 to move towards the button 148 under the elastic force of the first spring. The limit plate 146 moving towards the button 148 drives the limit rod 147 to move. The limit rod 147 moving contacts the inner wall of the protection groove 149 and limits the button 148. The button 148 cannot be pressed under the limitation of the limit rod 147.
