[0002] A speed reducer is a transmission device used to reduce input speed and increase output torque accordingly. It is widely used in various industrial equipment. Its main purpose is to achieve efficient energy conversion and transmission through a combination of a series of gears, worms or other transmission elements without a large amount of power loss. It is an independent component consisting of a gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing. It is often used as a speed reduction transmission device between the prime mover and the working machine, and plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, the top of the reducer body is protected by the tripod and the arc-shaped top plate. The tripod strengthens the impact resistance of the arc-shaped top plate, and the reinforcing ribs are used to strengthen the impact resistance of the fixed side plate, thereby improving the overall firmness and protection capability of the fixed side plate.

[0020] 2. In the present invention, the protective cover cooperates with the supporting side plate to further improve the protection strength of the side. When the outer surface of the fixed side plate is impacted, the fixed side plate is fixed to the side of the reducer body through the connecting plate to protect the side of the reducer body. When the impact force is too large, the connecting plate will be deformed to further absorb the impact force caused by the impact and reduce the probability of the reducer body being damaged by the impact. The reaction force of the support spring can offset the impact force of the rear end to a certain extent. At the same time, the pressing block and the rubber pad are deformed to reduce the impact force directly hitting the side cover. The side cover and the fixed side plate are used to achieve double protection and improve the protection effect of the reducer body.

[0021] 3. In the present invention, the side covers and the arc-shaped top plate are provided to form a relatively closed environment for the reducer assembly. The function of the fan assembly is utilized to accelerate the flow of air on the outer surface of the reducer body, and the air is discharged from the bottom of the side covers through the inside of the flow air duct, thereby preventing the protective cover from being sleeved on the outer surface of the reducer assembly, thereby affecting the original heat dissipation of the reducer assembly, and thereby improving the heat dissipation effect of the reducer assembly. At the same time, the side covers and the arc-shaped top plate are sleeved on the top of the reducer assembly, and the filter net is utilized to intercept dust, thereby making the reducer body work in a relatively closed environment, thereby reducing dust and impurities from entering the interior of the reducer body, thereby affecting the service life of the reducer body.

[0022] 4. In the present invention, the pressing rod is driven by the detection ball to jump inside the detection frame, and contacts the bottom of the vibration sensor through the L-shaped frame and the contact rubber pad, so that the vibration sensor detects the vibration amplitude when the rotating shaft rotates. When the vibration amplitude is large, the controller can control the extension of the electric telescopic rod, and the piston pushes the lubricating oil inside the sleeve through the connecting hose, squeezed out from the oil outlet needle and dripped between the gears, thereby reducing the friction of the transmission between the gears, realizing the effect of automatic lubrication, and improving the working stability of the reduction gear body.

[0034] The top of the reducer body 11 is protected by the tripod 210 and the arc-shaped top plate 22. The tripod 210 strengthens the impact resistance of the arc-shaped top plate 22. The side cover 21 and the arc-shaped top plate 22 form a relatively closed environment for the reducer assembly 1, thereby reducing dust from falling into the interior of the protective cover 2, and further preventing dust and impurities from entering the interior of the reducer body 11 and affecting the service life of the reducer body 11.

[0035] like Figure 5 As shown, the supporting side panel 3 includes a fixed side panel 31 and reinforcing ribs 32. The number of the reinforcing ribs 32 is multiple and evenly distributed on the outer side of the fixed side panel 31. A bottom frame 35 is fixedly installed at the bottom of the fixed side panel 31. A plurality of first embedded blocks 33 are fixedly installed at the upper end of the fixed side panel 31 close to the side cover 21. A plurality of second embedded blocks are fixedly installed at the side of the bottom frame 35 close to the side cover 21. Connecting plates 34 are fixedly installed at both ends of the fixed side panel 31 by bolts. The reinforcing ribs 32 are used to enhance the impact resistance of the fixed side panel 31 and improve the overall firmness of the fixed side panel 31.

[0036] like Figure 3 As shown, the reducer assembly 1 includes a reducer body 11, a support base 12 and fixed columns 13 fixedly installed at the four corners of the top of the support base 12, the bottom of the reducer body 11 is fixedly installed with the support base 12, both sides of the support base 12 are provided with movable grooves 14, and both sides of the reducer body 11 are located inside the movable grooves 14. Support bars 16 are fixedly installed on both sides of the reducer body 11, and a fixing flange 18 is fixedly installed on one side of the reducer body 11. A rotating shaft 19 is provided at one end of the reducer body 11, and the rotating shaft 19 is rotatably installed inside the fixing flange 18. A connecting groove 110 is opened on the top of the fixing flange 18, and mounting blocks 17 are fixedly installed at both ends of the reducer body 11. The side of the fixing column 13 is fixedly connected to one end of the connecting plate 34 by bolts.

[0037] Among them, the first embedded block 33 and the second embedded block are movably sleeved in the interior of the fixed sleeve block 23 and the sleeve groove 15 respectively, and the interior of the fixed sleeve block 23 and the sleeve groove 15 are both provided with support springs 36. The sides of the first embedded block 33 and the second embedded block are respectively connected to the support springs 36 inside the fixed sleeve block 23 and the sleeve groove 15, and the side of the fixed side plate 31 close to the side cover 21 is fixedly installed with a pressing protrusion 37, and the position of the pressing protrusion 37 corresponds to the rubber pad 24.

[0038] The two ends of the fixed side plate 31 are fixedly connected to the two fixed columns 13 on one side of the support base 12 through the connecting plate 34, so that the fixed side plate 31 is fixed to the side of the fixed column 13. At this time, the rubber pad 24 and the pressing protrusion 37 are in a state of mutual contact, and the support spring 36 is in an extended state. The strength of the connecting plate 34 is less than the strength of the fixed side plate 31 and the fixed column 13. By arranging the protective cover 2 and the supporting side plate 3 to cooperate with each other, the protection strength of the side is further improved. When the outer surface of the fixed side plate 31 is impacted, the fixed side plate 31 is fixed to the side of the reducer body 11 through the connecting plate 34 to protect the side of the reducer body 11. When the impact force When the tension is too large, the connecting plate 34 will be deformed to further absorb the impact force caused by the collision and reduce the probability of the reducer body 11 being damaged by the impact. When the connecting plate 34 is deformed, the fixed side plate 31 moves toward the side of the side cover 21. At the same time, the first embedded block 33 and the second embedded block move inside the fixed sleeve block 23 and the sleeve groove 15 respectively. The reaction force of the support spring 36 can offset the impact force of the rear end to a certain extent. At the same time, the pressing protrusion 37 and the rubber pad 24 are deformed to reduce the impact force directly hitting the side cover 21. The side cover 21 and the fixed side plate 31 are used to achieve double protection, thereby improving the protection effect of the reducer body 11.

[0039] Embodiment 2, as Figure 1 - Figure 5 As shown, a reducer with a protective structure, both ends of the side cover 21 are fixedly installed with mounting blocks 25, the mounting blocks 25 are movably sleeved on the outer surface of the mounting block 17, and are fixedly connected to the mounting block 17 by bolts, the side cover 21 is movably sleeved on the outer surface of the reducer body 11, and an air flow passage 6 is formed between the side cover 21 and the two sides of the reducer body 11, a support frame 28 is fixedly installed inside the air inlet pipe 26, a fan assembly 29 is fixedly installed inside the support frame 28, and rubber pads 24 are fixedly installed on both sides of the outer surface of the side cover 21.

[0040] The support bar 16 is used to support the reducer body 11 and the side cover 21, and an air flow passage 6 is formed between the side cover 21 and the reducer body 11. The fan assembly 29 is used to accelerate the flow of air on the outer surface of the reducer body 11, so that the air passes through the top of the reducer body 11, passes through the inside of the air flow passage 6, and is discharged from the bottom of the side cover 21, thereby preventing the protective cover 2 from being sleeved on the outer surface of the reducer assembly 1, affecting the original heat dissipation of the reducer assembly 1, and improving the heat dissipation effect of the reducer assembly 1. At the same time, the side cover 21 and the arc-shaped top plate 22 are sleeved on the top of the reducer assembly 1, and the filter 27 is used to intercept dust, so that the reducer body 11 works in a relatively closed environment, reducing dust and impurities from entering the interior of the reducer body 11 and affecting the service life of the reducer body 11.

[0041] Embodiment three, as Figure 1 - Figure 5 As shown, a reducer with a protective structure, the lubricating device 5 includes a fixed base 51, a sleeve 52 fixedly installed on the top of the fixed base 51, a piston 58 and an oil outlet needle 56, an electric telescopic rod 57 is fixedly installed on the left end of the sleeve 52, one side of the electric telescopic rod 57 is fixedly connected to the piston 58, the piston 58 is movably sleeved inside the sleeve 52, an injection pipe 53 is fixedly installed on the side of the top of the sleeve 52 away from the electric telescopic rod 57, a pipe cover 54 is threadedly installed on the top of the injection pipe 53, a connecting hose 55 is fixedly installed on the side of the sleeve 52 away from the electric telescopic rod 57, one end of the connecting hose 55 is fixedly installed with the oil outlet needle 56, the electric telescopic rod 57 is electrically connected to a controller 59, one end of the controller 59 is fixedly connected to a connecting line, and one end of the connecting line is fixedly installed with a second terminal 510.

[0042] The fixed base 51 and the controller 59 are both fixedly mounted on the top of the reducer body 11 , and the oil outlet needle 56 is fixedly mounted on the top of the reducer body 11 and is located at the gear inside the reducer body 11 .

[0043] like Figure 7 As shown, the detection component 4 includes a detection frame 41, an inner frame 48 and a vibration sensor 49. A movable cavity 42 is opened at the lower end of the detection frame 41, and a pressing rod 43 is movably sleeved on the lower end of the detection frame 41. A detection ball 44 is rotatably installed on the bottom of the pressing rod 43. A fixed block is fixedly sleeved on the upper end of the detection frame 41, and the fixed block is movably sleeved on the upper end of the detection frame 41. A cavity is opened at the upper end of the detection frame 41, and a movable spring 45 is movably sleeved inside the cavity. The two ends of the movable spring 45 are respectively located between the inner wall of the cavity and the fixed block. An L-shaped frame 46 is fixedly sleeved on the outer surface of the lower end of the pressing rod 43, and a contact rubber pad 47 is fixedly installed on the top of the L-shaped frame 46.

[0044] Among them, the detection frame 41 is fixedly installed on the outside of one end of the side cover 21, the pressing rod 43 is movably sleeved inside the connecting groove 110, the detection ball 44 is rollingly installed on the outer surface of the rotating shaft 19, and the vibration sensor 49 is fixedly installed on the upper end of the inner frame 48. One side of the vibration sensor 49 is fixedly connected with a fixed wire 410, and one end of the fixed wire 410 is fixedly installed with a first terminal 411, and the first terminal 411 is clamped and installed with the second terminal 510.

[0045] The inner frame 48 is fixedly mounted on the inner wall of the side cover 21 close to the connecting groove 110 , the contact rubber pad 47 and the L-shaped frame 46 are movably sleeved inside the inner frame 48 , and the contact rubber pad 47 is movably mounted on the bottom of the vibration sensor 49 .

[0046] The first terminal 411 is plugged into the second terminal 510, so that the detection ball 44 detects the rotating shaft 19 rotating inside the fixed flange 18. When the inside of the gear lacks lubricating oil, the friction between the gear transmission will increase, which will cause the vibration of the rotating shaft 19 on the gear to increase. The vibration of the rotating shaft 19 drives the pressing rod 43 to jump inside the detection frame 41 through the detection ball 44, and contacts the bottom of the vibration sensor 49 through the L-shaped frame 46 and the contact rubber pad 47, so that the vibration sensor 49 detects the vibration amplitude when the rotating shaft 19 rotates. When the vibration amplitude is large, the controller 59 can control the electric telescopic rod 57 to extend, and the piston 58 pushes the lubricating oil inside the sleeve 52 through the connecting hose 55 and squeezes it out of the oil outlet needle 56, so that the lubricating oil drips between the gears, reducing the friction of the transmission between the gears and realizing the effect of automatic lubrication.

[0047] It should be noted that the present invention is a reducer with a protective structure. When installing, first plug the first terminal 411 and the second terminal 510, then sleeve the side cover 21 on the top of the reducer body 11, so that the mounting block 25 is sleeved on the outer surface of the mounting block 17 and fixed by bolts, and the tripod 210 is supported on the top of the reducer body 11. At this time, the fixed side plate 31 is located on the outside of the fixed column 13, and the connecting plate 34 is located on the side of the fixed column 13, and the connecting plate 34 is fixed to the fixed column 13 by bolts;

[0048] At this time, the pressing rod 43 passes through the inside of the connecting groove 110, so that the detection ball 44 is pressed against the outer surface of the rotating shaft 19. The pressing rod 43 is subjected to pressure and moves upward, so that the movable spring 45 is in a compressed state. The contact rubber pad 47 on the top of the L-shaped frame 46 is pressed against the bottom of the vibration sensor 49. The outer surface of the rotating shaft 19 is detected by the detection ball 44. When the inside of the gear lacks lubricating oil, the friction between the gear transmission will increase, which will cause the vibration of the rotating shaft 19 on the gear to increase. The vibration of the rotating shaft 19 is The detection ball 44 drives the pressing rod 43 to jump inside the detection frame 41, and contacts the bottom of the vibration sensor 49 through the L-shaped frame 46 and the contact rubber pad 47, so that the vibration sensor 49 detects the vibration amplitude when the rotating shaft 19 rotates. When the vibration amplitude is large, the vibration sensor 49 transmits an electrical signal to enable the controller 59 to control the extension of the electric telescopic rod 57, and the piston 58 pushes the lubricating oil inside the sleeve 52 through the connecting hose 55 and squeezes out from the oil outlet needle 56, so that the lubricating oil drips between the gears to reduce the transmission of the gears;

[0049] When the reducer body 11 is working, the fan assembly 29 is used to accelerate the flow of air on the outer surface of the reducer body 11, so that the air passes through the top of the reducer body 11, passes through the inside of the air flow channel 6, and is discharged from the bottom of the side cover 21, thereby achieving heat dissipation on the surface of the reducer body 11;

[0050] When the outer surface of the fixed side plate 31 is impacted, the fixed side plate 31 is fixed to the outer side of the fixing column 13 through the connecting plate 34 to protect the side of the reducer body 11. When the impact force is too great, the connecting plate 34 will be deformed to further absorb the impact force caused by the impact and reduce the probability of the reducer body 11 being damaged by the impact. At this time, the fixed side plate 31 moves toward the side of the side cover 21. At the same time, the first embedded block 33 and the second embedded block move inside the fixed sleeve block 23 and the sleeve groove 15 respectively. The reaction force of the support spring 36 can be used to offset the impact force of the rear end to a certain extent. At the same time, the pressing protrusion 37 and the rubber pad 24 are deformed to reduce the impact force directly hitting the side cover 21. After the impact, it is only necessary to replace the deformed and damaged connecting plate 34, and re-fix the fixed side plate 31 to the fixing column 13 with the new connecting plate 34 using bolts.
