[0002] A servo motor can control speed, and the position accuracy is very accurate. It can convert a voltage signal into torque and rotational speed to drive a control object. The rotational speed of the servo motor rotor is controlled by an input signal and can respond quickly. In an automatic control system, it is used as an actuator and has characteristics such as a small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. By setting the outer shell, internal gear ring, bolt, bearing, output shaft, installation main body, insertion plate, stator of the movement main body, planetary gear, insertion rod, connecting plate and annular groove, after the power is turned on, a magnetic field is generated by the stator to drive the movement main body to rotate. The rotation speed of the movement main body is reduced by the planetary gear and the internal gear ring, and then the insertion rod drives the connecting plate and the output shaft to rotate in the installation main body, slowing down the rotation speed of the movement main body and then outputting it, so that the output rotation speed can be better controlled, which is convenient for the use of the servo motor;

[0016] 2. By setting bearings, output shafts, mounting blocks, mounting grooves, slots, cartridge cases, fixing grooves, fixing frames, guide wheels, fixing blocks, rubber blocks, first deformation grooves, connecting plates, fixing rods, rubber sleeves, rubber balls, inserting plates, connecting discs and annular grooves, the fixing frame can be pushed under the action of the rubber block, so that the guide wheels provided on the fixing frame are stably arranged in the annular grooves opened on the connecting disc. When the connecting disc rotates, the guide wheels roll in the annular grooves opened on the connecting disc, making the rotation of the connecting disc and the output shaft more stable. At the same time, the inserting plates provided on the bearings are arranged in the slots opened on the mounting blocks to install and limit the bearings. Under the action of the two mounting blocks and the cartridge case, it is convenient to directly remove the mounting blocks and the cartridge case from the outside of the output shaft, facilitating the maintenance of the output shaft. At the same time, the guide wheels and the rubber blocks can be directly taken out from the fixing grooves opened on the cartridge case to maintain the guide wheels and the rubber blocks. When the fixing frame is installed on one side of the rubber block through the fixing block, the fixing block and the fixing frame are limited by the rubber ball and the rubber block to prevent the rubber plate from falling off the surface of the fixing frame;

[0017] 3. By setting a rotating shaft, a fixing frame, a magnet plate, a limiting groove, a positioning groove, a mounting shell, a placing shell, a rubber strip, a limiting ball, a connecting rod, a pushing disc, a bottom plate, a second deformation groove, a U-shaped spring piece and a positioning ball, the mounting shell can be installed on the outside of the fixing frame and the magnet plate, preventing the outside of the magnet plate and the fixing frame. Without using glue and other winding fixing parts, the magnet plate can be limited, preventing the magnet plate from falling off and facilitating the maintenance of the magnet plate. At this time, the limiting ball provided in the positioning groove opened on the fixing frame prevents the placing shell and the mounting shell from falling off the outside of the fixing frame, making the installation of the magnet plate more stable. At the same time, the U-shaped spring piece can limit the positioning ball to prevent the rubber strip from falling off after the placing shell is taken out from the limiting groove opened on the fixing frame.

[0018] 4. By setting a first helical gear, a second helical gear, a protective shell, a crank, a connecting rod, a rocker, a limiting spring, a connecting shaft, a rod handle and a transmission shaft, when the first helical gear and the second helical gear rotate, the hunting phenomenon can be reduced, faults can be prevented, and stability can be improved. At the same time, through the four-link rotating structure, the rotation of the rod handle is more stable, and the use is safer through the protection of the protective shell.

The support and the connecting plate 12 are both arranged inside the mounting body 6. Through this setting, after the power is turned on, a magnetic field is generated by the stator 9 to drive the core body 8 to rotate. The rotation speed of the core body 8 is reduced by the planetary gears 10 and the internal gear ring 2, and then the plug rod 11 drives the connecting plate 12 and the output shaft 5 to rotate inside the mounting body 6, slowing down the rotation speed of the core body 8 and then outputting it, so that the output rotation speed is better controlled, facilitating the use of the servo motor.

[0042] As a further embodiment of the above invention: The mounting body 6 includes a mounting block 61, a clamping shell 64 and a guiding body 66.

Through this setting, the fixing frame 661 can be pushed under the action of the rubber block 664, so that the guiding wheel 662 arranged on the fixing frame 661 is stably arranged in the annular groove 13 formed in the connecting disk 12. When the connecting disk 12 rotates, the guiding wheel 662 rolls in the annular groove 13 formed in the connecting disk 12, making the rotation of the connecting disk 12 and the output shaft 5 more stable. At the same time, the plug plates 7 arranged on the bearing 4 are arranged in the slots 63 formed in the mounting block 61, so as to install and limit the bearing 4. Under the action of the two mounting blocks 61 and the clamping shell 64, it is convenient to directly remove the mounting block 61 and the clamping shell 64 from the outside of the output shaft 5, which is convenient for maintaining the output shaft 5. At the same time, the guiding wheel 662 and the rubber block 664 can be directly taken out of the fixing groove 65 formed in the clamping shell 64 for maintaining the guiding wheel 662 and the rubber block 664. When the fixing frame 661 is installed on one side of the rubber block 664 through the fixing block 663, the fixing block 663 and the fixing frame 661 are limited by the rubber ball 669 and the rubber block 664 to prevent the rubber plate from falling off the surface of the fixing frame 661.

[0043] As a further embodiment of the above invention: The movement main body 8 includes a rotating shaft 81, a fixing frame 82, a magnet plate 83, a mounting shell 86 and a limiting main body 87. A fixing frame 82 is fixedly connected to the outside of the rotating shaft 81. Magnet plates 83 are evenly distributed on the outside of the fixing frame 82. Mounting shells 86 are arranged on both the front and rear sides of the fixing frame 82 and the magnet plates 83. Evenly distributed limiting main bodies 87 are installed in the mounting shells 86. Limiting grooves 84 are provided on the outside of both the front and rear ends of the fixing frame 82.

U-shaped spring pieces 878 are arranged in both the front and rear sections of the rubber strip 872. Positioning balls 879 are arranged in both the front and rear ends of the rubber strip 872. One side of the positioning ball 879 is fixedly connected to the placement shell 871. The U-shaped spring piece 878 is arranged outside the positioning ball 879. Both the placement shell 871 and the bottom plate 876 are arranged in the limiting groove 84 opened in the fixing frame 82. The positioning groove 85 opened in the fixing frame 82 is arc-shaped. The outside of the end of the limiting ball 873 away from the connecting rod 874 is in close fit with the placement shell 871. Through this setting, the mounting shell 86 can be installed on the outside of the fixing frame 82 and the magnet plate 83, preventing the outside of the magnet plate 83 and the fixing frame 82. The magnet plate 83 can be limited without using glue and other winding fixing parts, facilitating the maintenance of the magnet plate 83 while preventing the magnet plate 83 from falling off. At this time, the limiting ball 873 arranged in the positioning groove 85 opened in the fixing frame 82 prevents the placement shell 871 and the mounting shell 86 from falling off the outside of the fixing frame 82, making the installation of the magnet plate 83 more stable. At the same time, the U-shaped spring piece 878 can limit the positioning ball 879, preventing the rubber strip 872 from falling off after the placement shell 871 is taken out from the limiting groove 84 opened in the fixing frame 82.

[0044] As a further embodiment of the above invention: A first helical gear 14 is installed on the outer side of one end of the output shaft 5.

Through this setting, the lever handle 22 can be driven to rotate, realizing the raising of the barrier gate. At the same time, the four-bar linkage structure is protected by the protective housing 16 to prevent damage.

[0045] During specific implementation: When this servo motor with planetary reduction and the gate lifting device using this motor are in use, first, the power is turned on. At this time, the controller controls the current to enter the stator 9. The stator 9 is energized to generate magnetic force, which drives the magnet plate 83 of the permanent magnet to rotate through the magnetic force. The magnet plate 83 drives the rotating shaft 81 to rotate through the fixing frame 82. The rotating shaft 81 drives the planetary gear 10 to rotate. The planetary gear 10 rotates under the action of the internal gear ring 2. The planetary gear 10 pushes the connecting disk 12 to rotate through the inserting rod 11. The connecting disk 12 drives the output shaft 5 to rotate within the two bearings 4, thereby achieving power output. When the connecting disk 12 drives the bearing 4 to rotate, the guiding wheel 662 rolls within the annular groove 13 opened on the connecting disk 12. At the same time, the guiding wheel 662 rotates within the fixing frame 661. At this time, the rubber block 664 pushes the fixing frame 661 and the guiding wheel 662 to always fit with the connecting disk 12 under the action of its own elastic force, so that the connecting disk 12 rotates stably. During maintenance, directly remove the bolt 3, and then the mounting block 61, the cartridge case 64, the bearing 4, the output shaft 5, and the connecting disk 12 can be taken off from the front end of the housing 1 together. At this time, the mounting block 61 and the cartridge case 64 can be directly separated to both sides, and the output shaft 5 can be taken off for maintenance. At the same time, the rubber block 664 can be taken out from the fixing groove 65 opened on the cartridge case 64 through the guiding wheel 662 and the fixing frame 661. Then, pull the rubber block 664. The rubber block 664 drives the fixing rod 667 to move through the connecting plate 666. The fixing rod 667 drives the rubber ball 669 to move through the rubber sleeve 668. The rubber ball 669 is gradually deformed and enters the fixing block 663 until the rubber ball 669 is taken out from the fixing block 663. At this time, the rubber block 664 or the damaged guiding wheel 662 can be replaced separately. After replacement, the rubber block 664 is inserted back into the fixing groove 65 opened on the cartridge case 64. At this time, the rubber block 664 is in close fit with the inner wall of the fixing groove 65 opened on the cartridge case 64 through its own elastic force, realizing the installation of the rubber block 664 and the guiding wheel 662. Then, the mounting block 61 is installed outside the maintained output shaft 5 and the bearing 4. At this time, the inserting plate 7 provided on the bearing 4 is inserted into the slot 63 opened on the mounting block 61 to limit the bearing 4. At the same time, the cartridge case 64 is installed outside the connecting disk 12. At this time, the guiding wheel 662 is arranged within the annular groove 13 opened on the connecting disk 12. The guiding wheel 662 is in close fit with the connecting plate 666 through the elastic force of the rubber block 664. Then, the internal gear ring 2 and the planetary gear are installed outside the rotating shaft 81. The cartridge case 64 is installed within the internal gear ring 2. At this time, the inserting rod 11 penetrates the connecting disk 12, and the bolt 3 penetrates the fixing case and the internal gear ring 2 and is threadedly connected to the housing 1. When maintaining the core body 8, directly disassemble the housing 1 and take out the core body 8. Then, the installation shell 86 can be pulled. The installation shell 86 drives the placing shell 871 to move. At this time, the limiting ball 873 is pushed to move under the action of the arc-shaped positioning groove 85 opened on the fixing frame 82. The limiting ball 873 drives the push plate to move within the rubber strip 872 through the connecting rod 874.The rubber strip 872 deforms under the action of the second deformation groove 877, and the limit ball 873 is received into the placement shell 871, so as to gradually take out the placement shell 871 from the fixing frame 82. At this time, the magnet plate 83 can be directly removed from the fixing frame 82 for maintenance. At the same time, the limit ball 873 can be pushed. The limit ball 873 pushes the rubber strip 872 to move. At this time, the bottom plate 876 is not limited by the fixing frame 82, and the rubber strip 872 pushes the bottom plate 876 to gradually leave the placement shell 871. The limit ball 873 and the bottom plate 876 take out the rubber strip 872 from the placement shell 871 for maintenance. After the maintenance is completed, the rubber strip 872 is reinstalled into the placement shell 871. At this time, the U-shaped spring piece 878 is engaged outside the positioning ball 879 to limit the rubber strip 872. Then, the placement shell 871 is reinstalled into the limit groove 84 opened by the fixing frame 82. The positioning ball 879 is engaged in the positioning groove 85 opened by the fixing frame 82 under the action of the self-elasticity of the rubber strip 872, so as to position the placement shell 871 and the installation shell 86. The installation shell 86 can prevent the magnet plate 83 from falling off the fixing frame 82, which is convenient for the maintenance of the magnet plate 83. When the lifting rod device is used, the lifting rod device is directly installed outside the installation block of this servo motor. At this time, the installation shaft 5 is installed on the first helical gear 14 of the lifting rod device. The servo motor is started, and the servo motor drives the first helical gear 14 to rotate through the output shaft 5. The first helical gear 14 drives the second helical gear 15 to rotate. The second helical gear 15 drives the transmission shaft 23 to rotate. The transmission shaft 23 drives the crank 17 to rotate. The crank 17 drives the rocker 19 to rotate. The rocker 19 drives the connecting rod 18 to rotate. The connecting rod 18 drives the connecting shaft 21 to rotate. At the same time, the connecting rod 18 pulls the limit spring 20 to stretch. The limit spring 20 stretches the connecting rod, making the rotation of the connecting rod 18 more stable. At the same time, the connecting shaft 21 drives the rod handle 22 to rotate. The rod handle 22 drives the lifting rod to move, realizing the lifting of the rod.
