[0002] A speed reducer is an independent component consisting of gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the prime mover and the working machine, and plays a role in matching speed and transmitting torque between the prime mover and the working machine or actuator. It is widely used in modern machinery in steel plants.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this invention, the magnetic connection between the electromagnet and the guide block is used to control the lifting and lowering adjustment of the guide block and the L-shaped rod, thereby realizing the height adjustment of the pressure plate and the sealing gasket inside the storage box.

[0031] 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. Example 1

[0032] Reference Figure 1-8 As shown: A low-vibration, fatigue-resistant speed reducer for steel plants includes a speed reducer housing 1, a sealing cover 12 snapped onto the top of the speed reducer housing 1, a bearing cover 11 fixedly connected to one side of the speed reducer housing 1, a bearing cover 13 provided on one side of the bearing cover 11, a bearing cover 13 fixedly connected to one side of the bearing cover 13, a base 2 provided at the bottom of the bearing cover 13, a pad 22 fixedly connected to the top of the base 2, a heat dissipation plate 4 provided on one side of the pad 22, the bottom of the heat dissipation plate 4 snapped onto the base 2, a buffer plate 21 snapped onto the top of the base 2, the top of the buffer plate 21 overlapping the bearing cover 13, a buffer pad 211 fixedly connected to one side of the buffer plate 21, a buffer pad 211 overlapping one side of the buffer pad 211, and an auxiliary mechanism 7 provided on one side of the buffer pad 211.

[0033] The auxiliary mechanism 7 includes a storage box 71, a connecting block 75, and an L-shaped rod 78. The bottom of the storage box 71 is fixedly connected to an inner box 14, and the bottom of the inner box 14 is fixedly connected to the reducer housing 1. A pressure plate 711 is sleeved inside the storage box 71. A sealing gasket 712 is fixedly connected to the bottom of the pressure plate 711, and the top of the pressure plate 711 is fixedly connected to the L-shaped rod 78. One end of the L-shaped rod 78 is fixedly connected to the connecting block 75. An electromagnet 72 is provided below the connecting block 75. One side of the electromagnet 72 is engaged with the reducer housing 1. Two guide rods 74 are embedded in the top of the electromagnet 72. A guide block 77 is fixedly connected to the top of the guide rods 74, and the top of the guide block 77 is fixedly connected to the connecting block 75.

[0034] A spring 73 is fixedly connected to the top of the electromagnet 72. The top of the spring 73 is fixedly connected to the guide block 77. One side of the guide block 77 is slidably connected to the reducer housing 1.

[0035] One end of the L-shaped rod 78 passes through the inner box 14 and the reducer housing 1. The L-shaped rod 78 is slidably connected to the inner box 14, and an auxiliary plate 76 is provided above the L-shaped rod 78. One side of the auxiliary plate 76 is fixedly connected to the inner box 14.

[0036] A nozzle 761 is fixedly connected to one side of the auxiliary plate 76, and a connecting pipe 79 is fixedly connected to one side of the auxiliary plate 76. One end of the connecting pipe 79 passes through the pressure plate 711 and the sealing gasket 712, and a branch pipe 791 is fixedly connected to one side of the connecting pipe 79. The pressure plate 711 and the connecting pipe 79 are slidably connected. A one-way valve 713 is provided below the pressure plate 711, and one end of the one-way valve 713 is fixedly connected to the storage box 71.

[0037] In this embodiment, the sealing cover 12 provides sealing protection for the top of the reducer housing 1 and the inner box 14. Bearing covers 11 and 13 both contain bearings to facilitate rotation of the reducer's input and output ends. The bottom of the pad 22 is fixedly connected to the base 2, and its top overlaps with the bottom of the reducer housing 1, providing cushioning protection for the bottom of the reducer housing 1. The heat dissipation plate 4 has several heat dissipation fins, and its bottom engages with the base 2, facilitating its installation on the base 2. One side of the heat dissipation plate 4 penetrates the reducer housing 1 and overlaps with the side wall of the inner box 14, allowing for timely heat transfer from the surface of the inner box 14. The heat dissipation area of ​​the inner box 14 is increased to assist in the rapid heat dissipation of the inner box 14 and the internal lubricating oil. The top of the buffer plate 21 is arc-shaped to facilitate its fit with the bottom of the bearing cover 13. The bottom of the buffer plate 21 is snapped into the base 2 to facilitate the installation and removal of the buffer plate 21 on the base 2. A buffer pad 211 is installed on one side of the buffer plate 21. One end of the buffer pad 211 overlaps with the reducer housing 1. When the reducer housing 1 is subjected to vibration, the reducer housing 1 squeezes the buffer pad 211, and the elastic material buffer pad 211 is compressed to achieve buffering of the inner side of the buffer plate 21 and improve the protection effect of the base 2 on the reducer housing 1.

[0038] The built-in box 14 provides limiting assistance for the installation of the turbine 8 and worm gear 9. The bottom of the storage box 71 is fixedly connected to the built-in box 14, which supports the installation of the storage box 71. The storage box 71 contains lubricating oil. The top of the pressure plate 711 is fixedly connected to the connecting block 75 via an L-shaped rod 78. When the connecting block 75 moves up and down, it can drive the L-shaped rod 78 to rise and fall, thereby achieving synchronous adjustment of the pressure plate 711 and the sealing gasket 712. When the sealing gasket 712 moves down, the air pressure inside the storage box 71 increases, which can force the lubricating oil into the branch pipe 791 and the connecting pipe 79. The top of the connecting pipe 79 is connected to a pipe embedded inside the auxiliary plate 76. The lubricating oil can enter the auxiliary plate 76 through the connecting pipe 79 and be supplied to multiple nozzles 761 through the pipes, thereby spraying oil to maintain the side wall of the turbine 8 and the meshing point of the turbine 8 and worm gear 9. The L-shaped rod 78 passes through the decelerator. The guide block 77 is slidably connected to the reducer housing 1 on the side wall of the housing 1, which can limit the movement direction and range of the L-shaped rod 78. When the L-shaped rod 78 moves upward, the pressure plate 711 drives the sealing gasket 712 to move upward. The height difference between the bottom of the sealing gasket 712 and the lubricating oil surface gradually increases, and the lubricating oil no longer enters the connecting pipe 79, stopping the oil spraying and realizing intermittent oil spraying inside the built-in box 14. The one-way valve 713 connects the storage box 71 and the bottom of the inner cavity of the built-in box 14. When the pressure plate 711 moves downward, the oil pressure inside the storage box 71 is greater than the external oil pressure. At this time, the lubricating oil seals one side of the one-way valve 713, and the lubricating oil outside the storage box 71 will not enter the storage box 71 through the one-way valve 713. When the pressure plate 711 moves upward, the oil pressure on both sides of the storage box 71 is the same, and the external lubricating oil can enter the storage box 71 through the one-way valve 713 to replenish the lubricating oil inside the storage box 71.

[0039] The guide block 77 can be driven to rise and fall by the magnetic connection between the electromagnet 72 and the guide block 77. The top of the guide rod 74 is connected to the guide block 77 to guide the rise and fall of the guide block 77. A spring 73 is installed between the guide block 77 and the electromagnet 72. When the guide block 77 moves down, the spring 73 is compressed. When the electromagnet 72 is de-energized, the spring 73 tends to return to its original position, thereby realizing the upward adjustment of the guide block 77. Example 2

[0040] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a guide plate 15 is fixedly connected to one side of the inner wall of the built-in box 14, a filter screen 16 is fixedly connected to one side of the guide plate 15, a turbine 8 is provided above the filter screen 16, a worm gear 9 is engaged at the top of the turbine 8, and an output shaft 6 is fixedly connected to one end of the turbine 8.

[0041] One end of the output shaft 6 passes through the bearing cover 13. The output shaft 6 is fitted with a limit sleeve 61. A reinforcing rod 63 is fixedly connected to the bottom of the limit sleeve 61. One side of the reinforcing rod 63 is engaged with the buffer plate 21. Reinforcing rods 62 are fixedly connected to both sides of the reinforcing rod 63. The bottom of the reinforcing rod 62 is engaged with the base 2, and the reinforcing rod 62 is slidably connected to the base 2.

[0042] A locking block 81 is fitted onto one side of the turbine 8, and an extension rod 82 is fixedly connected to one side of the locking block 81. One side of the extension rod 82 is engaged with the inner box 14.

[0043] One end of the worm gear 9 passes through the bearing cover 13. A reinforcing component 5 is provided on one side of the worm gear 9. The reinforcing component 5 includes a limiting sleeve 51, a support rod 52, and a gear 53. The limiting sleeve 51 is sleeved with the worm gear 9. The bottom of the limiting sleeve 51 is fixedly connected to the support rod 52. One side of the support rod 52 meshes with the gear 53. A sleeve plate 54 is sleeved on one side of the gear 53. A supporting component 3 is provided below the sleeve plate 54.

[0044] The support component 3 includes a connecting plate 31, a connecting strip 33, and a second connector 34. One side of the connecting plate 31 is fixedly connected to the reducer housing 1. The second connector 34 is embedded inside the connecting plate 31. One end of the connecting strip 33 is sleeved on the bottom of the second connector 34, and the other end of the connecting strip 33 is sleeved on the first connector 32. The bottom of the first connector 32 is slidably connected to the base 2.

[0045] In this embodiment, one side of the guide plate 15 is fixedly connected to the inner box 14. The guide plate 15 can collect the lubricating oil thrown out by the turbine 8 onto the filter screen 16. The lubricating oil filtered by the filter screen 16 is collected at the bottom of the inner cavity of the inner box 14. One end of the turbine 8 is fixedly connected to the output shaft 6. The end of the output shaft 6 away from the turbine 8 can be connected to the drive structure. The limiting sleeve 2 61 is sleeved on the outside of the output shaft 6, which can realize the connection between the top of the reinforcing rod 2 63 and the output shaft 6. The reinforcing rod 1 62 supports the two sides of the reinforcing rod 2 63, forming a stable triangular structure, which can improve the reinforcing rod. The stability of the second 63 on the base 2 is achieved by using the second 63 to support the bottom of the output shaft 6, ensuring that the axis formed by the output shaft 6 and the turbine 8 remains balanced, reducing the positional offset and tilt of the turbine 8, and ensuring the meshing effect of the turbine 8 and the worm 9. The extension rod 82 and the locking block 81 are both set inside the inner box 14, located on one side of the first 62 of the reinforcing rod. After the two semi-circular locking blocks 81 are locked, they can form a ring. The ring is sleeved on the outside of the extension rod 82, which can assist the installation of the turbine 8 inside the inner box 14 and reduce the positional deviation of the turbine 8 during installation.

[0046] The limiting sleeve 51 is adjusted with the worm 9 to assist the top of the support rod 52 in supporting the worm 9. The support rod 52 has a serrated edge with a rack engaged on one side. The gear 53 is sleeved on one side of the sleeve plate 54. The gear 53 and the sleeve plate 54 are rotatably connected. One side of the gear 53 passes through the side wall of the sleeve plate 54 and meshes with the rack on the support rod 52. The rotation of the gear 53 can drive the support rod 52 to rise and fall inside the sleeve plate 54. After the height is adjusted, the support rod 52 is fixed by bolts on the sleeve plate 54 and the support rod 52, which improves the support effect of the worm 9 and reduces the bending deformation of the worm 9 after being subjected to force.

[0047] The connecting plate 31 is fixedly connected to the reducer housing 1. The two ends of the connecting strip 33 are rotatably connected to the first connecting piece 32 and the second connecting piece 34, respectively. The bottom of the first connecting piece 32 is engaged in the base 2 and slidably connected to the base 2. The connecting plate 31 and the reducer housing 1 can vibrate synchronously. When the connecting plate 31 vibrates, the connecting plate 31 drives the second connecting piece 34 to produce vertical displacement. When the second connecting piece 34 moves down, it drives the top of the connecting strip 33 to move down and applies force to the connecting strip 33. The end of the connecting strip 33 rotates and adjusts on the top of the first connecting piece 32. The angle between the connecting strip 33 and the first connecting piece 32 decreases, and the first connecting piece 32 is subjected to a downward force. At this time, the bottom of the first connecting piece 32 slides vertically in the inner cavity of the base 2, realizing buffer protection for both sides of the reducer housing 1.

[0048] The working principle and usage of this device are as follows: First, when the entire reducer is used in the steel plant, select the required drive motor. Connect one end of the worm 9 to the motor as the input. The rotation of the worm 9 drives the rotation of the worm wheel 8. The output shaft 6 on one side of the worm wheel 8 serves as the output. Connect the output to the steel plant equipment to drive the equipment. Due to the speed difference between the worm 9 and the worm wheel 8, the motor speed can be reduced. When the worm 9 and the worm wheel 8 rotate, the electromagnet 72 is energized and de-energized using an external controller. The electromagnet 72 is magnetically connected to the bottom of the guide block 77. The guide rod 74 is a telescopic mechanism with an inner and outer rod sleeve. When the electromagnet 72 is energized, the guide block 77 drives the connecting block 75 to move downwards. At this time, the L-shaped rod 78 and the pressure plate 711 move downwards, pressurizing the inside of the storage box 71. Lubricating oil flows through the branch pipe 7... 91 enters the connecting pipe 79 and is sprayed out through the nozzle 761 on one side of the auxiliary plate 76 to spray oil on the bottom of the worm 9 and the side of the turbine 8. Excess lubricating oil is filtered by the filter screen 16 and collected at the bottom of the inner cavity of the built-in box 14 to ensure the lubrication effect on the turbine 8. Since the turbine 8 and the worm 9 are meshed, when the worm 9 contacts the turbine 8, the lubricating oil remaining on the surface of the turbine 8 can be coated onto the worm 9 to achieve maintenance of the turbine 8 and the worm 9 and reduce the wear of the worm 9 and the turbine 8. When the electromagnet 72 is de-energized, the spring 73 drives the guide block 77 to move upward, which in turn drives the L-shaped rod 78 and the pressure plate 711 to move upward, thereby achieving the reset of the pressure plate 711. At this time, the lubricating oil inside the built-in box 14 can flow into the storage box 71 through the one-way valve 713 to avoid the lubricating oil level inside the storage box 71 from dropping too quickly and affecting subsequent use.

[0049] The heat sink 4 penetrates the reducer housing 1 and overlaps with the inner box 14 on one side. A motor is set on one side of the heat sink 4 to accelerate the heat dissipation on the surface of the heat sink 4, which can help cool down the inner box 14 and the reducer housing 1. The pad 22 is made of elastic rubber strip, which can absorb sound and protect the bottom of the reducer housing 1. When the vibration inside the reducer housing 1 is transmitted to the outside, the buffer pad 211 on one side of the reducer housing 1 can buffer the lateral vibration. The connecting plate 31 and the second connecting piece 34 move down, which drives the top of the connecting strip 33 to move down, adjusting the tilt angle between the connecting strip 33 and the first connecting piece 32. The bottom of the first connecting piece 32 slides in the base 2, thereby adjusting the depth of the bottom of the first connecting piece 32 inserted into the base 2. The friction during the sliding process consumes energy, which helps to buffer the vertical vibration of the reducer housing 1 and achieve low vibration of the reducer.

[0050] During the installation and use of the reducer, rotate gear 53 on one side of sleeve plate 54 to adjust the height of support rod 52 and fix it with bolts. Use limit sleeve 1 51 to support worm 9 and reduce axial offset of worm 9. Install two extension rods 82 in the inner box 14 to engage the two locking blocks 81. One end of worm gear 8 passes through locking block 81 and connects to output shaft 6. This guides and limits the installation of worm gear 8 in the inner box 14, ensuring the accuracy of the assembly of worm gear 8 and worm 9. Move reinforcing rod 1 62 on the top of base 2 until one side of reinforcing rod 2 63 engages with buffer plate 21. At this time, use bolts to connect the bottom of reinforcing rod 1 62 to base 2 to limit the position of reinforcing rod 1 62. One side of limit sleeve 2 61 overlaps with bearing cover 2 13 to support output shaft 6.

[0051] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
