Embodiment
[0025] A worm and worm gear reducer that can avoid resonance, including a reducer body 1 arranged on a mounting base plate. A docking plate 2 is fixed to the bottom of the reducer body 1. A buffer plate 3 is arranged below the docking plate 2. Rubber buffer pads 4 are attached to both the top and bottom of the buffer plate 3. The mutually remote sides of the rubber buffer pads 4 are respectively attached to the bottom of the docking plate 2 and the mounting base plate. Auxiliary buffer components used in cooperation with the reducer body 1 are arranged on both the docking plate 2 and the buffer plate 3. The auxiliary buffer components include a cavity 7 opened in the buffer plate 3. Multiple groups of first dampers 8 are uniformly fixed to the bottom of the inner cavity of the cavity 7. The top ends of the first dampers 8 are fixed to the top of the inner cavity of the cavity 7. Multiple groups of rubber debris 11 are uniformly filled in the cavity 7. On the front and back sides of both sides of the docking plate 2 and the top of the mounting base plate, movable seats 13 are fixed. Second dampers 14 used in cooperation with the reducer body 1 are rotatably installed in the left and right two groups of movable seats 13. <m
[0026] Specifically, by using multiple groups of first dampers 8 in the buffer plate 3, the vibration force generated by the reducer body 1 can be initially buffered in a timely manner. And the design of the rubber debris 11 can fill the positions in the cavity 7 where the first dampers 8 are not placed, but the filling is not full, and the filling margin is at least 30%, so as to utilize the rubber debris 11 to further absorb vibration energy through friction energy consumption, weaken the transmission of high-frequency vibration, and assist the first dampers 8 to further improve the buffering effect. At the same time, the design of the second dampers 14, combined with the two groups of rubber buffer pads 4, can further absorb the vibration force and buffer the vibration force, thereby effectively preventing the generation of resonance and improving the anti-resonance effect of the reducer body 1.
[0027] Multiple groups of rubber sleeves 9 adapted to the first dampers 8 are uniformly fixed in the cavity 7. The first dampers 8 are located inside the rubber sleeves 9.
[0028] Specifically, the design of the rubber sleeves 9 can isolate the first dampers 8, effectively preventing the rubber debris 11 from contacting the first dampers 8 and affecting the normal operation of the first dampers 8.
[0029] Multiple groups of ventilation holes 10 are uniformly opened on the surface of each group of rubber sleeves 9.
[0030] Specifically, the design of the multiple groups of ventilation holes 10 can timely discharge the gas in the rubber sleeves 9 when the first dampers 8 generate slight displacement due to the vibration force, avoiding affecting the normal up and down expansion and contraction of the rubber sleeves 9, and enabling the air in the rubber sleeves 9 to circulate to ensure the normal operation of the first dampers 8.
[0031] The number of the first dampers 8 in the cavity 7 is at least six groups.
[0032] Specifically, the limitation on the number of the first dampers 8 in the cavity 7 can improve the buffering and counteracting effect on the vibration force. At the same time, while buffering the vibration force, the overall strength of the buffer plate 3 can be further improved.
[0033] A plurality of groups of auxiliary air holes 12 communicating with the cavity 7 are uniformly formed around the buffer plate 3.
[0034] Specifically, the design of the auxiliary air holes 12 is to discharge the gas in the cavity 7 and introduce new air, so that the gas in the cavity 7 can circulate, avoiding affecting the normal operation of the first damper 8.
[0035] A plurality of groups of fixing bolts 5 capable of penetrating through the rubber buffer pads 4 are sequentially arranged on both sides of the docking plate 2 and the buffer plate 3 in the front-back direction. Threaded holes 6 for threaded docking with the fixing bolts 5 are formed in the docking plate 2, the buffer plate 3 and the mounting bottom plate.
[0036] Specifically, by using the threaded connection between the fixing bolts 5 and the threaded holes 6, the butt joint plate 2, the buffer plate 3 and the rubber buffer pad 4 can be quickly fixed on the installation base plate, and the reducer body 1 can be quickly assembled. Moreover, the butt joint tightness between the butt joint plate 2 and the buffer plate 3 can be further improved, avoiding easy detachment. The specific usage process is as follows: When the reducer body 1 is running, vibration force will be generated. At this time, the rubber buffer pad 4 above can initially buffer and offset the vibration force. At the same time, multiple groups of first dampers 8 in the cavity 7 can perform secondary buffering and offsetting of the vibration force transmitted to the buffer plate 3, converting the vibration kinetic energy into heat energy for consumption. At the same time, since the places in the cavity 7 where the first dampers 8 are not placed are filled with rubber debris 11, at this time, the rubber debris 11 can further absorb the vibration energy through friction energy consumption, weakening the transmission of high-frequency vibration. At this time, as an auxiliary means to cooperate with the first dampers 8, the vibration force can be offset three times. At the same time, the rubber buffer pad 4 below, using its own performance, can offset the vibration force four times. At the same time, multiple groups of second dampers 14 arranged on both sides of the butt joint plate 2 can further absorb and offset the vibration force, so as to perform a fifth buffering and offsetting of the vibration force. At this time, the first dampers 8, the second dampers 14, the rubber debris 11 and the rubber buffer pad 4 can form a multi-form and multi-directional multiple buffering structure for the reducer body 1, which can timely absorb and offset the vibration force generated during the operation of the reducer body 1, thus effectively preventing the generation of resonance, improving the anti-resonance effect of the reducer body 1, and further effectively avoiding accelerating the aging speed of the internal parts of the reducer body 1 due to resonance. At the same time, it can avoid affecting the transmission accuracy of the reducer body 1. By using multiple groups of first dampers 8 in the buffer plate 3, the vibration force generated by the reducer body 1 can be initially buffered in a timely manner. And the design of the rubber debris 11 can fill the positions in the cavity 7 where the first dampers 8 are not placed, but the filling is not full, and the filling margin is at least 30%, so as to use the rubber debris 11 to further absorb the vibration energy through friction energy consumption, weakening the transmission of high-frequency vibration. The auxiliary first dampers 8 can further improve the buffering effect. At the same time, the design of the second dampers 14, combined with two groups of rubber buffer pads 4, can further absorb the vibration force and buffer the vibration force, thus effectively preventing the generation of resonance and improving the anti-resonance effect of the reducer body 1. The design of the rubber sleeve 9 can isolate the first dampers 8, effectively avoiding the rubber debris 11 contacting the first dampers 8 and affecting the normal operation of the first dampers 8. The design of multiple groups of ventilation holes 10 can timely discharge the gas in the rubber sleeve 9 when the first dampers 8 generate slight displacement due to the vibration force, avoiding affecting the normal up and down expansion and contraction of the rubber sleeve 9, and enabling the air in the rubber sleeve 9 to circulate, ensuring the normal operation of the first dampers 8. The limitation of the number of first dampers 8 in the cavity 7 can improve the buffering and offsetting effect on the vibration force. At the same time, it can also further improve the overall strength of the buffer plate 3 while buffering the vibration force. The design of the auxiliary air holes 12,So as to discharge the gas in the cavity 7 and introduce new air, so that the gas in the cavity 7 can be circulated, avoiding affecting the normal operation of the first damper 8. By using the threaded connection of the fixing bolts 5 and the threaded holes 6, the docking plate 2, the buffer plate 3 and the rubber buffer pad 4 can be quickly fixed on the installation base plate, and the reducer body 1 can be quickly assembled. Moreover, the docking tightness between the docking plate 2 and the buffer plate 3 can be further improved, avoiding easy detachment.
[0037] Therefore, by setting the auxiliary buffer assembly and cooperating with two groups of rubber buffer pads, a multi-form and multi-directional multiple buffer structure can be formed, which can absorb and offset the vibration force generated during the operation of the reducer body layer by layer. Thus, the generation of resonance can be effectively prevented, the anti-resonance effect of the reducer body is improved, and further, the reduction of the tightness of the connection of the internal parts of the reducer due to resonance can be effectively avoided, and at the same time, the transmission accuracy of the reducer body can be prevented from being affected.
