Description

Technical Field

[0001] The invention relates to a reducer, in particular to a low-noise and environment-friendly reducer applied in the technical field of reducers. Background Art

[0002] The reducer matches the speed and transmits the torque between the prime mover and the working machine. The reducer is a relatively precise independent component consisting of a gear transmission, a worm transmission, or a gear-worm transmission enclosed in a rigid housing. The reducer can reduce the speed and increase the torque. It can be divided into single-stage and multi-stage according to the number of transmission stages. It matches the speed and transmits the torque between the prime mover and the working machine or actuator, and is widely used in modern machinery.

[0003] The invention patent with the publication number CN11335734A discloses a low-noise reducer, including a housing, the inner side wall of the housing is connected to a driving gear through an input shaft, the inner side wall of the housing is connected to a rotating shaft through an output shaft, and the side wall of the rotating shaft is sleeved with a driven gear. When the reducer is working, the lubricating oil with a lower temperature near the side wall of the housing can be sucked from the oil inlet pipe, and sprayed through the oil outlet pipe and the oil guide pipe to impact the meshing part of the driven gear and the driving gear for lubrication, thereby ensuring the transmission efficiency of the reducer and making the noise of the reducer lower. At the same time, it is possible to detect whether the tooth surfaces of the driven gear and the driving gear have pit defects, which is convenient for timely maintenance, and according to the detection situation, the meshing position of the driven gear and the driving gear can be automatically adjusted, and the defective end can be moved to avoid meshing with the driving gear, thereby ensuring low noise when the reducer is working.

[0004] The above implementation scheme takes into account that the reducer may generate noise during operation due to insufficient gear lubrication or pit defects on the gears, but it does not take into account that the increase in torque when the reducer is running and the reduction ratio of the reducer will cause the reducer to generate high-frequency vibrations. The high-frequency vibrations of the reducer will resonate with the equipment, increasing the noise of the reducer during operation, which will have a greater impact on the use of the reducer. In addition, the high-frequency vibrations will also reduce the normal service life of the reducer. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the torque increase during the operation of the reducer and the reduction ratio of the reducer will cause the reducer to generate high-frequency vibrations. The high-frequency vibrations of the reducer will resonate with the equipment, increasing the noise during the operation of the reducer, which will have a great impact on the use of the reducer. In addition, the high-frequency vibrations will also reduce the normal service life of the reducer.

DETAILED DESCRIPTION

[0032] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figure 1-Figure 5 A low-noise and environmentally friendly reducer is shown, including a reduction support assembly 1, the reduction support assembly 1 includes a reduction support shell 101, a heat dissipation groove 102 opened on the reduction support shell 101, a heat dissipation hole is opened in the heat dissipation groove 102, a temperature sensor 103 is arranged in the reduction support shell 101, a driving member 2 is fixedly installed on the outer wall of the reduction support shell 101, a reduction device 3 is installed at the output end of the driving member 2, a load 4 is connected to the output end of the reduction device 3, and an air guide device 9 is connected through the reduction support shell 101, the air guide device 9 is connected to the air source assembly, and the air guide device 9 is used to introduce gas into the reduction support shell 101.

[0035] The deceleration device 3 is installed inside the deceleration support housing 101. The deceleration device 3 includes a deceleration mechanism 301 and a fixed rod 302 fixed on the deceleration mechanism 301. A guide plate 303 is fixed to the other end of the fixed rod 302. The fixed rod 302 passes through the heat dissipation hole of the deceleration support housing 101. The guide plate 303 is arranged corresponding to the heat dissipation slot 102. The heat dissipation slot 102 has multiple guide plates 303 and the heat dissipation slot 102 has multiple through holes. The fixed rod 302 has multiple guide plates 303. The multiple guide plates 303 are fixed on the deceleration mechanism 301. The fixed rod 302 is arranged corresponding to the through holes. The multiple fixed rods 302 are respectively fixedly connected to the multiple guide plates 303. When the deceleration mechanism 301 moves downward, the fixed rod 302 is driven to move synchronously. The fixed rod 302 drives the guide plate 303 to move synchronously. After the deceleration mechanism 301 moves a certain distance, the guide plate 303 will be close to the heat dissipation slot 102 to block the heat dissipation hole.

[0036] A stabilizing device 6 is installed on the top of the outer wall of the deceleration mechanism 301. The stabilizing device 6 includes a stabilizing base 601 fixedly connected to the inner wall of the deceleration support shell 101, and an airbag 602 installed on the stabilizing base 601. The airbag 602 is connected to the air source component. The inflation of the airbag 602 will push the deceleration mechanism 301 to move downward, and at the same time is used to absorb the vibration generated by the deceleration mechanism 301.

[0037] A shock absorbing device 7 is installed at the bottom of the outer wall of the deceleration mechanism 301. The shock absorbing device 7 includes a shock absorbing base 701 fixedly connected to the inner wall of the deceleration support shell 101, an airbag groove 702 provided on the shock absorbing base 701, and an airbag 2 703 installed in the airbag groove 702. The airbag 2 703 is connected to the air source component. A spring groove 1 706 is provided on the shock absorbing base 701. A spring 1 707 is provided in the spring groove 1 706. The spring 1 707 is fixedly connected to the shock absorbing base 701. A universal joint mechanism is installed on the airbag 2 703. The universal joint mechanism includes a universal joint base 704. The universal joint base 704 is fixedly installed on the airbag 2 703. A universal groove is provided, in which a roller 705 is arranged, an electric push rod 708 is provided on the shock absorbing base 701, and the instruction module is electrically connected to the electric push rod 708. A pressure sensor 710 is provided on the shock absorbing base 701. The inflation of the airbag 703 will push the deceleration mechanism 301 to move upward, and at the same time it is used to absorb the vibration generated by the deceleration mechanism 301. The universal joint mechanism can make the shock absorbing device 7 move with the deceleration mechanism 301, so that the airbag 703 can more fully absorb the vibration generated by the deceleration mechanism 301. The pressure sensor 710 is used to detect the strength of the vibration generated by the deceleration mechanism 301, so that the airbag 1 602 and the airbag 2 703 can make corresponding responses.

[0038] A deceleration intelligent controller 5 is installed on the deceleration support shell 101, and a main control module, a command module, a monitoring module, and a decibel meter are arranged in the deceleration intelligent controller 5. The main control module is electrically connected to the command module and the monitoring module respectively, the command module is electrically connected to the driving part 2 and the air source component respectively, and the monitoring module is electrically connected to the temperature sensor 103, the pressure sensor 710 and the decibel meter respectively.

[0039] When the reducer needs to start running, the main control module in the reduction intelligent controller 5 will control the action of the driving part 2 through the instruction module, output power to the reduction mechanism 301, and after the reduction of the reduction mechanism 301, the power will be output to the load 4. Vibration will be generated during the operation of the reduction mechanism 301. In order to eliminate the vibration, the instruction module will control the air source component to inflate the airbag 1 602 of the stabilizing module and the airbag 2 703 of the shock absorbing module. There are multiple stabilizing devices 6, and the multiple stabilizing devices 6 are evenly distributed along the circumference of the reduction mechanism 301. Pressure sensors 2 603 are arranged on the multiple stabilizing devices 6. The detection module is electrically connected to the pressure sensor 2 603. The main control module will collect the pressure data of the pressure sensor 1 710 and multiple pressure sensors 2 603 through the detection module, and compare the multiple pressure data with different specified pressures (the main control module is preset with the specified pressures corresponding to different pressure sensors in the current state). By analyzing the multiple pressure data, the vibration intensity and main vibration direction of the reduction mechanism 301 can be obtained.

[0040] According to the vibration intensity of the deceleration mechanism 301, the total amount of inflation of the plurality of airbags 1 602 and the second airbag 703 is controlled by the command module to achieve a better shock absorption effect. When the main control module determines that the overall pressure data are greater than the specified pressure, the command module will control the air source assembly to inflate the airbags 1 602 and the second airbag 703 at the same time, so that the plurality of stabilizing devices 6 and the shock absorbing devices 7 are squeezed toward the deceleration mechanism 301 at the same time, and then control the electric push rod 1 708. The electric push rod 1 708 is provided with a plurality of electric push rods 1 708, which are respectively installed at the four corners of the shock absorbing base 701 to reduce the vibration intensity of the deceleration mechanism 301. A positioning block 709 is provided on the shock base 701, and the positioning block 709 is arranged corresponding to the electric push rod 1 708. A positioning groove corresponding to the output end of the electric push rod 1 708 is opened on the positioning block 709, so that the output end of the electric push rod supports the positioning groove, thereby enhancing the stability of the shock absorbing device 7. When the stabilizing device 6 and the shock absorbing device 7 fix the position of the speed reduction mechanism 301, the command module controls the air source assembly to stop inflating the airbag 1 602 and the airbag 2 703. At this time, most of the vibration of the speed reduction mechanism 301 will be absorbed by the airbag 1 602, the airbag 2 703 and the spring 1 707.

[0041] The main control module will collect the noise data of the decibel meter through the detection module, and compare the noise data with the specified noise (the main control module is preset with the specified noise in the current state). If the noise data is lower than the specified noise, no action is required. If the noise data is higher than the specified noise, the command module will control the air source component to stop inflating the airbag 2 703 and continue to inflate the airbag 1 602, and then control the electric push rod 1 708 to retract the output end of the electric push rod, so that the deceleration mechanism 301 moves downward. During the downward movement of the deceleration mechanism 301, the fixed rod 302 and the guide plate 303 will be driven to move synchronously. The closer the guide plate 303 is to the heat sink 102, the more noise diffused from the heat sink 102 is reflected and absorbed by the guide plate 303. The deceleration mechanism 301 continues to move downward until the guide plate 303 is close to the heat sink 102, or the noise data is less than the specified noise, the command module controls the air source component to stop inflating the airbag 1 602, and controls the output end of the electric push rod 1 708 to support the positioning groove.

[0042] Since the heat dissipation slot 102 is blocked by the guide plate 303, the heat generated by the speed reduction mechanism 301 cannot be dissipated from the speed reduction support housing 101 in time, which may cause the speed reduction mechanism 301 to overheat and damage the internal parts. Therefore, after the heat dissipation hole is blocked, the main control module will collect the temperature data of the temperature sensor 103 through the detection module, and compare the temperature data with the specified temperature (the specified temperature in the current state is preset in the main control module). When the temperature data is greater than the specified temperature, the instruction module controls the air source component to guide the air device 9. The air guide device 9 includes an air guide pipe 901, and the deceleration support shell 101 is connected with the air source component through the air guide pipe 901. A solenoid valve 902 is arranged on the air guide pipe 901. The instruction module is electrically connected to the solenoid valve 902, and then the solenoid valve 902 is controlled to open. Gas is filled into the deceleration support shell 101, and the heat of the deceleration mechanism 301 is absorbed, so that the heat flows out along the active gap between the deceleration mechanism 301 and the deceleration support shell 101 with the gas, so as to maintain the heat dissipation efficiency of the deceleration mechanism 301 and reduce the influence of heat on the deceleration mechanism 301.

[0043] The vibration direction of the reduction mechanism 301 is not completely fixed, and is affected by multiple factors such as load 4, rotation speed, reduction ratio, etc. The main control module can obtain the main vibration direction of the reducer by analyzing multiple pressure data, and control the inflation ratio of multiple airbags 602 through the command module according to the main vibration direction. The command module controls the air source component to inflate the airbag 602 of the stabilizing device 6 set in the main vibration direction, so that the amount of gas filled in the airbag 602 here is higher than the amount of gas filled in the airbag 602 at other places. At the same time, the command module controls the electric push rod 708 in the shock absorbing device 7 to slightly retract the output end of the electric push rod 708 in the main vibration direction, so that the shock absorbing device 7 can better absorb the vibration generated by the reduction mechanism 301, and greatly reduce the noise generated by the reduction mechanism 301. When the noise data is less than the specified noise, the command module controls the air source component to stop inflating the multiple airbags 602.

[0044] The second implementation method:

[0045] Figure 6-Figure 9A low-noise and environmentally friendly reducer is shown. Different from the first embodiment, the output end of the reduction mechanism 301 is additionally provided with a slow-moving device 8 fixedly connected thereto, and the other end of the slow-moving device 8 is connected to the load 4. The slow-moving device 8 includes a slow-moving support shell 801, and a driving groove is provided on the slow-moving support shell 801. An output shaft connected to the load 4 is inserted in the driving groove. An electric push rod 803 is installed on the inner wall of the driving support shell. A locking mechanism 802 is fixedly installed on the output end of the electric push rod 803. A spring groove 804 is provided on the electric push rod 803. A spring 805 is provided in the spring groove 804. Both ends of the spring 805 are fixedly connected to the spring groove and the output end of the electric push rod 803 respectively. A torque sensor is provided in the driving groove. The instruction module is electrically connected to the electric push rod 803, and the monitoring module is electrically connected to the torque sensor; the locking mechanism 802 includes a fixed locking plate 806 and a dynamic locking plate 807. The fixed locking plate 806 is fixedly installed on the slow-moving support shell. 801 inner wall, the output end of the electric push rod 2 803 is fixedly mounted with a support body 808, a dynamic locking piece 807 is mounted on the support body 808, a plurality of fixed locking pieces 806 are provided, and the plurality of fixed locking pieces 806 are evenly distributed along the axial direction of the slow-motion support housing 801, a plurality of dynamic locking pieces 807 are provided, and the dynamic locking pieces 807 are evenly distributed along the axial direction of the slow-motion support housing 801, and the plurality of fixed locking pieces 806 and the plurality of dynamic locking pieces 807 are cross-arranged, and the plurality of dynamic locking pieces 807 and the fixed locking pieces 806 are mutually locked. Mutual friction realizes the transmission of the power of the reduction mechanism 301 to the load 4. When the load 4 increases suddenly, the reducer will make a violent noise. Therefore, the load 4 is detected by the torque sensor in the driving slot, so that when the load 4 suddenly increases, the electric push rod 803 controls its output end to retract, so that the output end of the reduction mechanism 301 is temporarily decoupled from the load 4. After the motor is increased to the corresponding speed, the output end of the reduction mechanism 301 is coupled with the load 4 to reduce the noise emitted by the reducer.

[0046] During the operation of the speed reduction mechanism 301, the load 4 may suddenly increase, which will generate huge pressure on the gears inside the speed reduction mechanism 301, causing friction between the gears, generating large noise, and affecting the surrounding environment. When the load 4 suddenly increases, the main control module will collect the torque data of the torque sensor through the detection module, and compare the torque data with the specified torque (the main control module is preset with the specified torque in the current state). When it is found that the torque data is greater than the specified torque, the command module will control the output end of the electric push rod 2 803 to retract. The output end of the electric push rod 803 retracts to drive the support body 808 to move synchronously, and the support body 808 drives the dynamic locking plate 807 to move synchronously, so that the dynamic locking plate 807 is no longer tightly attached to the fixed locking plate 806. At this time, the power at the output end of the reduction mechanism 301 is no longer output to the load 4, and the instruction module will control the driving member 2 again to increase its speed. When the speed of the driving member 2 increases, the instruction module controls the output end of the electric push rod 803 to extend forward, so that the dynamic locking plate 807 is tightly attached to the fixed locking plate 806 again, and the power of the reduction mechanism 301 is output to the load 4 again, thereby driving the load 4.

[0047] During operation, if the load 4 suddenly increases to a level that may damage the reducer, the torque generated will exceed the maximum value of the friction generated by the dynamic locking plate 807 and the fixed locking plate 806, decoupling the load 4 from the output end of the reduction mechanism 301. The torque data is much larger than the specified torque. At this time, the main control module cuts off the power to the entire deceleration device 8 to avoid damage to the electric push rod 2 803 due to excessive torque, which makes its output end unable to be retracted. At this time, the spring 2 805 is in a stretched state. After the electric push rod 2 803 is powered off, the spring 2 805 pulls the dynamic locking plate 807 back so that it is no longer tightly fitted with the fixed locking plate 806.

[0048] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
