[0025] like Figures 1 to 4 As shown, a suspended seismic-resistant hard-toothed reducer comprises a mounting plate 1 and a hard-toothed reducer body 2, the bottom of the hard-toothed reducer body 2 is fixedly connected with a reducer fixing plate 3, the top of the mounting plate 1 is fixedly connected with support plates 4 on both sides close to the hard-toothed reducer body 2, and the side walls of the support plates 4 are provided with shock-absorbing components for buffering and shock-absorbing the reducer fixing plates 3. Through the shock-absorbing components, the hard-toothed reducer body 2 is shock-absorbing, so as to prevent the hard-toothed reducer body 2 from being easily affected by vibration and impact, resulting in aggravated wear of the internal gears, and even failures such as breakage and falling off, which seriously affect the service life and performance stability of the reducer.

[0026] For further information, see Attachment Figure 2 and Figure 3As shown, the shock absorbing assembly includes a lower pressing plate 5 slidably connected to the side wall of the supporting plate 4, the bottom two sides of the lower pressing plate 5 are fixedly connected with a first rotating block 6, the bottom of the first rotating block 6 is rotatably connected with an extrusion rod 7, one end of the extrusion rod 7 is rotatably connected with a second rotating block 8, the bottom of the second rotating block 8 is fixedly connected with a shock absorbing slider plate 9, the side wall of the supporting plate 4 is fixedly connected with two fixed plates 10, a sliding rod 11 is fixedly connected between the opposite surfaces of the fixed plates 10, the inner wall of the shock absorbing slider plate 9 is adapted to the outer wall of the sliding rod 11, the shock absorbing slider plate 9 is slidably connected to the outer wall of the sliding rod 11, the outer wall of the sliding rod 11 is sleeved with a shock absorbing spring 12, and the two ends of the shock absorbing spring 12 are respectively fixedly connected Connected to the side wall of the shock-absorbing slider plate 9, the shock-absorbing assembly also includes an outer shock-absorbing cylinder 13 fixedly connected to the side wall of the shock-absorbing slider plate 9, the number of the outer shock-absorbing cylinders 13 is two, the interiors of the two outer shock-absorbing cylinders 13 are slidably connected with inner shock-absorbing cylinders 14, one end of the inner shock-absorbing cylinder 14 is fixedly connected to the side wall of the other shock-absorbing slider plate 9, one end of the inner shock-absorbing cylinder 14 slidably connected to the interior of the outer shock-absorbing cylinder 13 is fixedly connected with a sealing plug 15, damping rods 16 are fixedly connected to both sides of the bottom of the lower pressure plate 5, and the outer wall of the damping rod 16 is sleeved with a buffer spring 17, one end of the top of the buffer spring 17 is fixedly connected to the bottom of the lower pressure plate 5, and the other end of the buffer spring 17 is fixedly connected to the top of the mounting plate 1;

[0027] When the shock absorbing assembly is used, after the hard-toothed reducer body 2 is subjected to vibration or impact, the hard-toothed reducer body 2 transmits the vibration to the reducer fixing plate 3, and then the reducer fixing plate 3 transmits the vibration to the support plate 4, and the support plate 4 drives the lower pressure plate 5 to move downward and squeezes the squeezing rod 7 through the first rotating block 6, and the two ends of the squeezing rod 7 rotate on the first rotating block 6 and the second rotating block 8 and squeeze the second rotating block 8, thereby pushing the second rotating block 8 to rotate on the sliding rod 11, and then the second rotating block 8 will squeeze the middle of the sliding rod 11 The shock absorbing spring 12 at the position will shrink to absorb the vibration, so as to achieve shock absorption. At this time, the inner shock absorbing cylinder 14 on both sides of the shock absorbing slider plate 9 will slide in the outer shock absorbing cylinder 13, and the inner shock absorbing cylinder 14 will drive the sealing plug 15 to slide inside the outer shock absorbing cylinder 13. The second rotating block 8 will squeeze the shock absorbing spring 12 in the middle of the sliding rod 11 and push the sealing plug 15 to squeeze and compress the air inside the outer shock absorbing cylinder 13, so as to further achieve the effect of buffering and shock absorption of the hard gear surface reducer body 2;

[0028] At the same time, when the lower pressure plate 5 is pressed down, the damping rod 16 and the buffer spring 17 will be squeezed, and the contraction of the damping rod 16 and the buffer spring 17 will further play a shock-absorbing role. At the same time, the damping rod 16 is used to prevent the shock-absorbing spring 12 and the buffer spring 17 from rebounding quickly, thereby ensuring that the hard-toothed surface reducer body 2 can more smoothly restore a stable state after being impacted, reducing the secondary impact caused by rapid rebound. The shock-absorbing component can efficiently absorb and disperse the vibration and impact energy of the hard-toothed surface reducer body 2, significantly reduce the vibration transmitted to the hard-toothed surface reducer body 2 and the entire equipment, and improve the stability and service life of the equipment. The sliding of the inner shock-absorbing cylinder 14 in the outer shock-absorbing cylinder 13 and the compressed air mechanism provide an additional buffer layer. This multi-stage buffer design can more effectively cope with vibrations of various intensities and frequencies, and avoid the hard-toothed surface reducer body 2 being easily affected by vibration and impact during operation, resulting in increased wear of the internal gears, and even failures such as breakage, falling off and loosening, making the equipment run more stable.

[0029] For further information, see Attachment Figure 4 As shown, the sealing plug 15 is made of rubber material, and the outer wall of the sealing plug 15 is tightly attached to the inner wall of the outer shock-absorbing cylinder 13 to form an enclosed space. The enclosed space is formed by the inner wall of the outer shock-absorbing cylinder 13, and the squeezing force of the inner shock-absorbing cylinder 14 will drive the sealing plug 15 to squeeze the air in the outer shock-absorbing cylinder 13 and compress the air in the outer shock-absorbing cylinder 13, thereby achieving a practical shock-absorbing effect.

[0030] Furthermore, the reducer fixing plate 3 is in an arc shape, and the shape of the reducer 3 increases the contact area with the hard-toothed reducer body 2, making it more firm and stable when on the reducer fixing plate 3.

[0031] Furthermore, bolt inserting plates are fixedly connected to both sides of the mounting plate 1, and the mounting plate 1 can be conveniently fixed by the bolt inserting plates.

[0032] Working principle: When the shock-absorbing assembly is used, after the hard-toothed reducer body 2 is vibrated or impacted, the hard-toothed reducer body 2 transmits the vibration to the reducer fixing plate 3, and then the reducer fixing plate 3 transmits the vibration to the support plate 4, and the support plate 4 drives the lower pressure plate 5 to move downward and squeeze the extrusion rod 7 through the first rotating block 6. The two ends of the extrusion rod 7 rotate on the first rotating block 6 and the second rotating block 8 and squeeze the second rotating block 8, thereby pushing the second rotating block 8 to rotate on the sliding rod 11, and then the second rotating block 8 will squeeze the sliding rod 11. The shock-absorbing spring 12 in the middle part will shrink and absorb the vibration to achieve shock absorption. At this time, the inner shock-absorbing cylinder 14 on both sides of the shock-absorbing slider plate 9 will slide in the outer shock-absorbing cylinder 13. The inner shock-absorbing cylinder 14 will drive the sealing plug 15 to slide inside the outer shock-absorbing cylinder 13. The second rotating block 8 will squeeze the shock-absorbing spring 12 in the middle part of the sliding rod 11 and push the sealing plug 15 to squeeze and compress the air inside the outer shock-absorbing cylinder 13, thereby further achieving the effect of buffering and shock-absorbing the hard-toothed reducer body 2.
