Description

Technical Field

[0001] The present invention relates to the technical field of assembly equipment, and particularly to an auxiliary meshing system for a multi-stage gear set of an intelligent gas meter gearbox. Background Art

[0002] The electromechanical valve of a gas meter is used to realize the opening and closing of the gas meter and prevent jamming. The electromechanical valve of the gas meter mainly consists of a motor, a gearbox (speed-changing gearbox), and a valve rod actuator. During the automatic processing of the speed-changing gearbox, a gear shaft and a gear set need to be installed on the cover of the speed-changing gearbox. After the installation is completed, the workpiece is discharged and enters the next process.

[0003] When installing the gear set, the gear set is a multi-stage multi-layer gear set composed of multiple double gears and single gears installed in a stacked structure one above the other. After all the gears are installed, it is also necessary to detect the meshing condition of the gear set to screen out gears with casting defects. Due to the problem of automatic assembly, it cannot be guaranteed whether the gear set is meshed in place after installation. Therefore, during the detection, due to incomplete or improper gear meshing, the detection fails and the parts are treated as scrap, resulting in an increase in the scrap rate and cost, and affecting the gear detection result. Therefore, we need to design an auxiliary system before the gear meshing detection after the gears are installed to assist the gear meshing, improve the meshing degree of the gears in the gear set, and avoid misdetection or increasing the difficulty of the subsequent process design during the subsequent detection. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an auxiliary meshing system for a multi-stage gear set of an intelligent gas meter gearbox, which can assist the gear meshing and simultaneously adjust the installation position of the gears, improving the gear installation accuracy and meshing accuracy.

[0005] The purpose of the present invention is mainly achieved through the following technical solutions: An auxiliary meshing system for a multi-stage gear set of an intelligent gas meter gearbox includes: a moving part for moving in a direction perpendicular to the rotation plane of the inner gears of the multi-stage gear set of the gearbox; a self-resetting deformable part connected to the moving part and moving with the moving part, and the self-resetting deformable part moves with the moving part to the upper end surface of the inner gears of the multi-stage gear set of the gearbox and presses down; an air blowing part arranged on one side of the moving part for continuously or intermittently blowing air to generate an air flow directed at one or more gears in the multi-stage gear set of the gearbox; and driving the inner gears of the multi-stage gear set of the gearbox to mesh based on the pressing down of the self-resetting deformable part and the air flow generated by the air blowing part.

[0006] Based on the above technical solution, the self-resetting deformable part is a self-resetting soft elastic part.

[0007] Based on the above technical solution, the self-resetting soft elastic part is a brush.

[0008] Based on the above technical solutions, the moving part is a vertically lifting screw, and the vertically lifting screw is connected with a lifting drive mechanism.

[0009] Based on the above technical solutions, the self-resetting deformation part is detachably connected to the moving part.

[0010] Based on the above technical solutions, the blowing direction of the air blowing part is parallel to the side surface of any gear in the multi-stage gear of the gearbox.

[0011] Based on the above technical solutions, the blowing direction of the air blowing part points to the tooth surface of one gear in the multi-stage gear of the gearbox or to the meshing part of any two gears in the multi-stage gear of the gearbox.

[0012] Based on the above technical solutions, the blowing direction of the air blowing part points to the inner tooth surface of the tooth groove of the first-stage or last-stage gear in the multi-stage gear of the gearbox.

[0013] Based on the above technical solutions, it further includes a lifting assembly, and the air blowing part is arranged on the lifting assembly.

[0014] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention drives the self-resetting deformation part to move through the moving part, and then squeezes the multi-stage gear set of the gearbox along the direction perpendicular to the rotation surface of the inner gears in the multi-stage gear set of the gearbox. When squeezing, the gears are pressed down to move axially along the gear shaft, so that the multi-layer gears can make up for the dimensional errors that are not installed in place during assembly when being pressed down, improving the gear assembly accuracy. And during the squeezing process, adjacent gears generate slight shaking, floating, tilting or rotation with each other. As a result, the teeth and tooth grooves between the gears can be better meshed together, ensuring the meshing accuracy, and the gear meshing auxiliary effect is good. Moreover, the self-resetting deformation part has a self-resetting deformation effect. When squeezing the gears, it can deform to reduce the rigid effect on the gears, and after deformation, it can increase the contact area with the gears, so that the squeezing force or the self-resetting deformation force can be evenly distributed to the gear contact surface, avoiding local squeezing from causing gear deformation and further ensuring the integrity of the gears.

[0016] 2. In the present invention, the self-resetting deformation part specifically adopts a self-resetting soft elastic part. Due to its softness, it can avoid damaging the gears due to rigid extrusion with the gears, extremely protecting the integrity of the gears. And its deformation also belongs to flexible deformation, and the deformation force will not increase sharply due to the increase of the deformation amount, which can avoid damaging the gears due to excessive deformation force over-squeezing the gears.

[0017] 3. The present invention uses a brush as a self - resetting soft elastic member. Since the brush head of the brush is composed of several fine bristles, when it presses against the internal gears of the multi - stage gear set of the gearbox, it can adaptively deform locally corresponding to the gear structure and gear position. Thus, it can contact different gears and generate different deformation directions and deformation amounts. It can not only drive the corresponding gears to shake, float, tilt or rotate well, causing different gears to produce different movements or displacement amounts, improving the meshing probability, but also minimize the damage and extrusion to the gears, and protect the gear structure extremely well.

[0018] 4. The present invention generates an air flow directed at one or more gears in the multi - stage gear set of the gearbox by continuously or intermittently blowing air through an air - blowing member. The air flow drives the multi - stage gear set of the gearbox to rotate, and realizes gear meshing during the rotation process, further improving the gear meshing effect. And because the gear rotation is effected by the air flow without rigid action, the interaction force between the gears during meshing is floating and will not constantly squeeze the gears. It can also protect the structural integrity of the gears extremely well during the process of assisting gear meshing.

[0019] The present invention also discloses a method for assisting the meshing of a multi - stage gear set of a gearbox. This method is used to assist the meshing of multi - stage gears after the installation of the multi - stage gear set of the gearbox, and includes: providing a self - resetting deformable member that can be pressed down to the upper end surface of one or more gears in the multi - stage gear set of the gearbox; and an air - blowing member that continuously or intermittently blows air to generate an air flow directed at one or more gears in the multi - stage gear set of the gearbox; driving the internal gears in the multi - stage gear set of the gearbox to mesh based on the pressing down of the self - resetting deformable member and the generated air flow.

[0020] This method for assisting the meshing of a multi - stage gear set of a gearbox drives the internal gears in the multi - stage gear set of the gearbox to shake, float, tilt or rotate by the deformation force of the self - resetting deformable member and the blowing air flow of the air - blowing member, either before or at the same time, driving the multi - stage gear set of the gearbox to rotate and mesh. It can efficiently assist the gear meshing of the multi - stage gear set of the gearbox, improve the gear meshing accuracy, and has no rigid contact with the gears in the multi - stage gear set of the gearbox, protecting the structural integrity of the internal gears in the multi - stage gear set of the gearbox extremely well, and can axially position the gears to ensure the assembly position and accuracy.

[0039] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with embodiments and drawings. The illustrative embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0040] As Figure 1 、 Figure 2 shown, the first embodiment of the present invention mainly discloses an auxiliary meshing system 10 of the multi-stage gear set of the intelligent gas meter transmission, which at least includes:

[0041] A moving part 101, which is used to move in a direction perpendicular to the rotation plane of the internal gear of the multi-stage gear set 20 of the transmission;

[0042] The self-resetting deformation member 102 is connected to the moving member 101 and moves with the moving member 101. The self-resetting deformation member 102 moves with the moving member 101 to the upper end surface of the internal gear of the multi-stage gear set 20 of the gearbox and presses down.

[0043] The air blowing member 103 is arranged on one side of the moving member 101 and is used for continuously or intermittently blowing air to generate an air flow directed at one or more gears in the multi-stage gear set 20 of the gearbox.

[0044] Based on the pressing down of the self-resetting deformation member 102 and the air flow generated by the air blowing member 103, the internal gears of the multi-stage gear set 20 of the gearbox are driven to mesh.

[0045] The intelligent gas meter multi-stage gear set auxiliary meshing system 10 is mainly used to assist the meshing of multi-stage gears after the installation of the multi-stage gear set of the gearbox, and it can be set after the installation process of the multi-stage gear set 20 of the gearbox.

[0046] When the multi-stage gear set auxiliary meshing system 10 of the intelligent gas meter gearbox is in use, the multi-stage gear set 20 of the gearbox is conveyed on the conveying track and installed. When it reaches the position of the multi-stage gear set auxiliary meshing system 10 of the intelligent gas meter gearbox, the conveying stops. At this time, the moving part 101 drives the self-resetting deformable part 102 to move, and makes the self-resetting deformable part 102 move along the direction perpendicular to the rotating surface of the internal gear of the multi-stage gear set 20 of the gearbox to the upper end surface of the internal gear of the multi-stage gear set 20 of the gearbox. The self-resetting deformable part 102 continues to press down until it contacts the upper end surface of the internal gear of the multi-stage gear set 20 of the gearbox. After contact, the internal gear of the gear set 20 of the gearbox is driven to translate axially along its respective gear shafts based on the downward pressure of the self-resetting deformable part 102 or its own self-resetting deformation force. Thus, the dimensional error caused by the gears not being installed in place during assembly can be compensated, enabling each gear to be installed at a suitable position on the shaft, improving the gear assembly accuracy. Secondly, when the gears translate axially along their respective gear shafts, they synchronously generate actions driven by the downward pressure of the self-resetting deformable part 102 or its own self-resetting deformation force. This action can be a slight shaking, floating, tilting or rotation. When the gears move, the teeth and grooves between the gears can better form plug-in pairs, thereby achieving the meshing effect with each other, ensuring the meshing position and accuracy of the internal gears in the gear set, and achieving a good gear meshing assistance effect. Moreover, in this embodiment, the self-resetting deformable part 102 has a self-resetting deformation effect. When squeezing the gears, it can deform to reduce the rigid effect on the gears, and after deformation, it can increase the contact area with the gears, enabling the squeezing force or the self-resetting deformation force to be evenly distributed to the gear contact surface, avoiding local extrusion causing gear deformation, and further ensuring the integrity of the gears. At the same time, the airflow generated by the air blowing part 103 serves as the driving force for the multi-stage gear set 20 of the gearbox. By means of the thrust generated by the airflow, one or more gears in the multi-stage gear set 20 of the gearbox are driven to rotate. During the rotation process, due to the actions of the airflow, the interaction force between the gears, and the gravity of the gears, etc., the gears can not only rotate under the action of the airflow, but also be accompanied by slight shaking, floating, tilting or rotation and other actions. Based on the above actions, the teeth and grooves between the adjacent gears that need to be meshed can better engage with each other, and then fully mesh, achieving a good auxiliary meshing effect. Moreover, when floating and shaking, the gears will not continuously generate interaction forces with each other, which can reduce the rigid interaction force between the gears, avoid gear damage caused by mutual extrusion, protect the gears, and ensure the integrity of the gears.

[0047] It should be noted that:

[0048] 1. The downward pressing of the self - resetting deformation part 102 and the air blowing of the air blowing part 103 are two actions, and both actions can achieve the effect of assisting gear meshing. When specifically used: they can be separated and performed successively, that is, after the self - resetting deformation part 102 presses downward, the air blowing part 103 blows air, or after the air blowing part 103 blows air, the self - resetting deformation part 102 presses downward; they can also be performed simultaneously. However, since their simultaneous actions will affect each other, when implementing this embodiment, to reduce their mutual influence, it is best that the downward pressure or deformation force of the resetting deformation part 102 is much greater than or much less than the air flow thrust of the air blowing part 103, taking one action as the main action and the other as the auxiliary action.

[0049] 2. During continuous or intermittent air blowing: Continuous air blowing means blowing air continuously at a fixed flow rate; or blowing air continuously while gradually increasing or decreasing the flow rate at a fixed rate.

[0050] First, blowing air continuously at a fixed flow rate means that the air blowing part 103 blows air continuously and uninterruptedly at a fixed flow rate. This method can provide a continuous and stable air flow for the multi - stage gear set 20 of the gearbox. Furthermore, the actions generated by the gears are relatively stable, the gears mesh more smoothly during meshing, and the meshing speed is fast and the effect is good. Further, the fixed flow rate can be 500 - 1000 ml / min. Further, the fixed flow rate can be 500 ml / min, 550 ml / min, 600 ml / min, 650 ml / min, 700 ml / min, 750 ml / min, 800 ml / min, 850 ml / min, 900 ml / min, 950 ml / min, 1000 ml / min. Specifically, the fixed flow rate is 750 ml / min.

[0051] Second, blowing air continuously while gradually increasing or decreasing the flow rate at a fixed rate means that the air blowing part 103 blows air while gradually increasing the air blowing volume at a fixed rate; or the air blowing part 103 blows air while gradually decreasing the air blowing volume at a fixed rate.

[0052] Among them, when the air blowing part 103 blows air while gradually increasing the air blowing volume at a fixed rate, that is, the air blowing part 103 blows air starting from zero or an initial air blowing volume, and gradually increases the air blowing volume at a fixed rate until it reaches the maximum air blowing volume and then stops or repeats. This method uses the method of gradually increasing the air blowing volume. First, the gears can be blown until they cannot rotate, but can be slightly shaken or floated. Then, the gears that are easy to mesh can be meshed first. Then, when the air blowing volume increases and the gears start to rotate, the rotation of adjacent gears can be realized through the rotation of the gears. Furthermore, by combining the above actions, the meshing of all gears can be achieved. This method has a higher success rate of gear meshing, but it takes a longer time.

[0053] The air blowing member 103 blows air at a gradually decreasing blowing air volume at a fixed rate, that is, the air blowing member 103 blows air starting from an initial blowing air volume, and gradually decreases the blowing air volume at a fixed rate until it reaches the minimum blowing air volume and then stops or repeats. In this way, a large gas flow is first used to drive the gears to mesh, which can achieve gear meshing over a large range or drive gears with a large misalignment to mesh. Then, the blowing air volume is gradually reduced, and further, through the fluctuations caused by the reduction of the gas, the gears are driven to produce slight shaking or floating, further driving all gears to mesh. This method has a high success rate of gear meshing and short time consumption. However, due to the large initial blowing air volume at the beginning, the gears are extremely likely to be damaged, resulting in gear damage.

[0054] The above fixed rate is a fixed value, which can be 50 - 300 ml / min. Further, the fixed rate can be 50 ml / min, 100 ml / min, 150 ml / min, 200 ml / min, 250 ml / min, 300 ml / min. Specifically, the fixed rate is 150 ml / min. The maximum blowing air volume is an upper limit value of the blowing air volume to avoid excessive extrusion or deformation of the gears caused by too large a blowing air volume, and it is preferably not greater than 1000 ml / min; similarly, the minimum blowing air volume is a lower limit value of the blowing air volume to avoid the inability to drive all gears to act due to too small a blowing air volume and lose the auxiliary effect, and the minimum blowing air volume is preferably not less than 500 ml / min.

[0055] Following the above, intermittent air blowing means that the air blowing member 103 blows air continuously at intervals of a fixed time. Blowing air at intervals of a fixed time means that the air blowing member 101 blows air intermittently with this fixed time as the blowing air interval, and each blowing air method can adopt the above continuous air blowing method for blowing air. Further, the fixed time can be 0.5 - 2.5 seconds. Further, the fixed time can be 0.5 second, 1 second, 1.5 seconds, 2 seconds, 2.5 seconds. Specifically, the fixed time is 1.5 seconds.

[0056] Based on the above air blowing methods, the intelligent gas meter gearbox multi - stage gear set auxiliary meshing system 10 of this embodiment can reasonably select the above air blowing methods or a combination of any methods for gear meshing assistance.

[0057] III. The airflow directed at one or more gears in the multi-stage gear set 20 of the transmission, i.e., the blowing direction of the air blowing member 103, can be as follows: directed at the tooth surface of one of the gears in the multi-stage gear set 20 of the transmission, such as the tooth surface of the first-stage or last-stage gear. In this blowing direction, the airflow is relatively concentrated, and it can drive all the gears to move and further engage in sequence based on the movement of one of the gears, from the local to the whole and in an orderly manner, resulting in more complete and thorough gear meshing and a high degree of gear meshing. The first-stage or last-stage gear herein refers to the gear located at the first stage or the last stage of the multi-stage gear set 20 of the transmission, or in terms of the transmission mode, the first-stage or last-stage gear refers to the driving transmission gear or the output transmission gear within the multi-stage gear set 20 of the transmission; this blowing direction can also be: directed at any multiple gears in the multi-stage gear set 20 of the transmission, such as the meshing position of any two gears that need to be meshed. This blowing method can drive the movement of at least two gears simultaneously, and then use the movement of at least two gears to drive multiple gears to mesh simultaneously. The gear meshing is faster, but there is no order in the gear meshing, and it is easy to have a situation where the gears get stuck and cannot mesh, resulting in a poor meshing effect. Further, the blowing direction of the air blowing member 103 is directed at the tooth surface of one gear in the multi-stage gear set 20 of the transmission or at the meshing position of any two gears in the multi-stage gear set 20 of the transmission. Specifically, the blowing direction of the air blowing member 103 is directed at the inner tooth surface of the tooth groove of the first-stage or last-stage gear in the multi-stage gear set 20 of the transmission.

[0058] Based on the above blowing directions, in actual applications, any one of the methods can be selected as needed or a combination of the two can be used to limit the blowing direction.

[0059] See Figure 2 , as a moving member 101 of the moving mechanism, at least one of its moving directions is along a direction perpendicular to the rotating surface of the gears in the multi-stage gear set 20 of the transmission, mainly serving as the direction control structure and conveying mechanism of the self-resetting deformation member 102.

[0060] As an alternative, when the rotating surface direction of the gears in the multi-stage gear set 20 of the transmission is horizontal, the moving member 101 can be selected as a vertical lifting screw to achieve lifting along a direction perpendicular to the rotating surface of the gears in the multi-stage gear set 20 of the transmission, and then directly drive the self-resetting deformation member 102 to press down to the upper end surface of the gears in the multi-stage gear set 20 of the transmission after descending. Further, in order to realize the lifting movement of the vertical lifting screw, the vertical lifting screw can be connected to a lifting drive mechanism, thereby realizing the automatic lifting of the vertical lifting screw. The lifting drive mechanism in this embodiment can be a driving motor, a robotic arm, a robot, etc.

[0061] Continue to refer to Figure 2, the self - resetting deformable member 102 is an auxiliary member with a deformation force and can automatically restore its shape to the original state. It can be driven by the moving member 101 to move downward to press on the upper end surfaces of one or more gears in the multi - stage gear set 20 of the transmission. It can be a non - elastic member, which only relies on the downward pressure and its own gravity to squeeze the gears in the multi - stage gear set 20 of the transmission, such as cotton, cloth, plastic, shims, etc.; or it can be an elastic member, mainly using the downward pressure and / or the deformation force of elastic deformation to drive the gears. The elastic member can be a metal or non - metal thin sheet, strip or wire, and the metal or non - metal can be plastic, rubber, sponge, memory sponge, shape - memory alloy, etc. The elastic member can also be an elastic reset structure composed of some deformable members and other mechanisms, such as a spring - flap mechanism composed of a spring and a flap, a brush composed of elastic bristles and a brush handle, etc.

[0062] It should be noted that for the convenience of replacement, the self - resetting deformable member 102 can be detachably connected to the self - resetting deformable member 102, such as bonding, snap - fitting, clamping, screw connection, etc.

[0063] As a preferred structure, the self - resetting deformable member 102 can be selected as a self - resetting soft elastic member. Through its soft characteristics, when it comes into contact with and deforms the multi - stage gear set 20 of the transmission, it can avoid rigid extrusion with the gears and damage the gears, which can well protect the integrity of the gears. Moreover, its deformation is also a flexible deformation, and the deformation force will not increase sharply with the increase of the deformation amount, which can avoid excessive extrusion of the gears due to too large a deformation force and damage the gears. And due to its soft characteristics, after deformation, it can disperse the downward pressure, gravity or deformation force to the entire contact surface of the gears, thereby dispersing the local stress and avoiding deformation and distortion caused by stress concentration, further protecting the gears.

[0064] Specifically, the self - resetting soft elastic member is a brush. After the bristles of the brush come into contact with the gears, they deform. Since the brush head of the brush is composed of several fine bristles, after it comes into contact with the multi - stage gear set 20 of the transmission, it can perform local adaptive deformation corresponding to the gear structure and gear position, so that it can contact different gears and generate different deformation directions and deformation amounts. It can not only drive the corresponding gears to move well, making different gears produce different movements or displacement amounts, improving the meshing probability, but also minimize the damage and extrusion to the gears, and well protect the gear structure.

[0065] Such as Figure 3As shown, the air blowing member 103 is mainly used for blowing air to drive one or more gears in the multi-stage gear set 20 of the gearbox to move and achieve meshing. The blowing direction of the air blowing member 103 is preferably parallel to the side surface of the gears in the multi-stage gear set 20 of the gearbox, that is, the blowing direction is parallel to the side surface of any gear in the multi-stage gear set 20 of the gearbox without an included angle. In this way, the air flow generated by the air blowing member 103 blows horizontally towards the gears in the multi-stage gear set 20 of the gearbox, avoiding the generation of component forces in other directions on the gears in the multi-stage gear set 20 of the gearbox, which may cause axial movement of the gears and jamming with each other, etc., and can avoid affecting the assembly accuracy and meshing effect. It should be noted that the side surface of the gear refers to the side surfaces on both sides of the gear that are perpendicular to the gear's central axis.

[0066] As the air blowing structure of this embodiment, the air blowing member 103 preferably uses a capillary tube for blowing air to ensure that the blowing direction and rate can be maintained for a long time after the gas is blown out. Further, the capillary tube can be made of a gooseneck tube to facilitate the adjustment of the blowing direction.

[0067] To better achieve the blowing effect of the air blowing member 103, the air blowing member 103 in this embodiment is also connected to a gas supply system with a flow control component. The gas supply system (not shown in the figure) of this embodiment can continuously supply gas to the air blowing member 103 and control the flow rate, flow velocity, etc. of the supplied gas under the action of the flow control component. Specifically, the flow control component can be a flow valve, a flow velocity valve, a regulating valve, etc., and the gas supply system can be an air pump, a cylinder, an airbag, etc.

[0068] As Figure 4 shown, the intelligent gas meter multi-stage gear set auxiliary meshing system 10 of this embodiment further includes a lifting component 104, and the air blowing member 103 is arranged on the lifting component 104. The lifting component 104 of this embodiment is used to drive the air blowing member 103 to lift, and thus the height of the air blowing member 103 can be adjusted as needed to meet the gear driving requirements.

[0069] Specifically, the lifting component 104 includes a bracket 1041 and a lifting block 1042 connected to the bracket 1041, and the air blowing member 103 is arranged on the lifting block 1042.

[0070] The bracket 1041 of this embodiment is used to fix and support the lifting block 1042, and the lifting block 1042 can lift along the bracket 1041 to drive the air blowing member 103 to lift. Specifically, the bracket 1041 is a support column, the lifting block 1042 is slidably arranged on the bracket 1041, and the lifting block 1042 is provided with a fixing member at a fixed position, such as a fixing screw, etc. During specific installation, the air blowing member 103 can be connected to the lifting block 1042 in a detachable manner, which is convenient for disassembly, replacement, and position adjustment.

[0071] As Figure 5 、 Figure 6As shown in the figure, the multi-stage gear set auxiliary meshing system 10 of the intelligent gas meter gearbox in this embodiment further includes an indexing plate 105. A tooling fixture 1051 is provided on the indexing plate 105. The gearbox cover 30 is positioned on the tooling fixture 1051. The upper end of the gearbox cover 30 is used to install the multi-stage gear set 20 of the gearbox. A divider 1052 is further provided at the lower end of the indexing plate 105. The moving part 101 and the air blowing part 103 are arranged outside the indexing plate 105 and are located after the installation process of the multi-stage gear set 20 of the gearbox.

[0072] The indexing plate 105 of this embodiment is used to intermittently convey the gearbox cover 30 to provide a specific conveying trajectory to complete the classified installation of the gears on the gearbox cover 30. Specifically, the tooling fixture 1051 is provided with a positioning groove paired with the gearbox cover 30 to fix the gearbox cover 30. The divider 1052 is used to drive the indexing plate 105 to rotate intermittently. During the rotation process, all the gears of the multi-stage gear set 20 of the gearbox are installed on the gearbox cover 30. After the gear installation is completed, it rotates to the position of the moving part 101 and the air blowing part 103 for auxiliary meshing operation, simplifying the gear installation and meshing process and improving the gear assembly and meshing accuracy.

[0073] As Figure 7 shown in the figure, based on the multi-stage gear set auxiliary meshing system 10 of the intelligent gas meter gearbox, the second embodiment of the present invention mainly discloses a multi-stage gear set auxiliary meshing method 40. The multi-stage gear set auxiliary meshing method 40 is used to assist the multi-stage gear meshing after the installation of the multi-stage gear set 20 of the gearbox, and it at least includes:

[0074] Step 401: Set a self-resetting deformable part 102, and the self-resetting deformable part 102 can be pressed down to the upper end surfaces of one or more gears in the multi-stage gear set 20 of the gearbox.

[0075] In this step 401, the self-resetting deformable part 102 can be arranged on the above-mentioned moving part 101 to drive it to press down through the moving part 101. When setting, the specific setting position can be after the process of the completion of the installation of the multi-stage gear set 20 of the gearbox. To avoid affecting the installation and conveying of the multi-stage gear set 20 of the gearbox, it can be arranged outside the conveying trajectory of the multi-stage gear 20, such as outside the indexing plate 103 as mentioned above.

[0076] Step 402: Set an air blowing part 103, and the air blowing part 103 blows continuously or intermittently to generate an air flow pointing to one or more gears in the multi-stage gear set 20 of the gearbox.

[0077] In this step, the setting position of the air blowing part 103 can refer to the self-resetting deformable part 102. After setting, ensure that the blowing end of the air blowing part 103 is arranged at an interval from the multi-stage gear set 20, and the interval size can be 3 - 5 cm according to the blowing direction.

[0078] And

[0079] Step 403: The self - resetting deformable part 102 presses down and the air - blowing part 103 blows air to generate an air flow, which drives the internal gears of the multi - stage gear set 20 of the gearbox to mesh, either successively or simultaneously.

[0080] In this step 403, when the self - resetting deformable part 102 presses down, different - direction deformation forces are generated based on the deformation, or an air flow is generated based on the air - blowing of the air - blowing part 103. By contacting the gear contact surface, or the tooth surface, side surface, etc. of the gear, the corresponding gears within the multi - stage gear set 20 of the gearbox can be driven to generate actions such as rotation, shaking, tilting, floating, etc. Through the above actions, the teeth and tooth grooves between adjacent gears can better form a pair and a meshing relationship, and then all the gears are driven to mesh in sequence, assisting the gear meshing of the multi - stage gear set 20 of the gearbox and completing the auxiliary gear meshing function after the installation of the multi - stage gear set 20 of the gearbox.

[0081] It can be foreseen that the order of step 401 and step 402 is not fixed, and the two can be arbitrarily replaced in order. This embodiment does not limit the order of the two steps.

[0082] This multi - stage gear initial meshing air - blowing method 40 for the gearbox drives the multi - stage gear set 20 of the gearbox to generate corresponding actions through the air - blowing air flow of the air - blowing part 101, driving the multi - stage gear set 20 of the gearbox to rotate and mesh, which can efficiently assist the gear meshing of the multi - stage gear set 20 of the gearbox, and has no rigid contact with the gears of the multi - stage gear set 20 of the gearbox, which extremely well protects the structural integrity of the internal gears of the multi - stage gear set 20 of the gearbox.

[0083] This multi - stage gear set auxiliary meshing method 40 for the gearbox drives the internal gears of the multi - stage gear set 20 of the gearbox to generate corresponding actions through the deformation force of the self - resetting deformable part 102 and the air - blowing air flow of the air - blowing part 103, either successively or simultaneously, driving the multi - stage gear set 20 of the gearbox to rotate and mesh, which can efficiently assist the gear meshing of the multi - stage gear set 20 of the gearbox, and has no rigid contact with the gears of the multi - stage gear set 20 of the gearbox, which extremely well protects the structural integrity of the internal gears of the multi - stage gear set 20 of the gearbox, and can axially position the gears to ensure the assembly position and accuracy.

[0084] The above - described specific implementation manners further elaborate on the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above - described are only the specific implementation manners of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
