Description

Technical Field

[0001] This application relates to the field of powder zinc diffusion technology, specifically to a device for preventing tooth skipping in a powder zinc diffusion furnace. Background Technology

[0002] Powder zinc diffusion involves burying a cleaned workpiece in the core of a zinc diffusion furnace containing a zinc diffusion agent. The workpiece is heated to below the melting point of zinc and held at that temperature for a certain period of time, thereby forming a zinc diffusion layer on the metal surface.

[0003] Powder zinc diffusion is usually carried out in a high-temperature (usually 400-500℃) and high-dust environment. Zinc diffusion agent particles may get stuck in the gear gaps, affecting the normal meshing of the gears and increasing the risk of tooth skipping. Tooth skipping can easily cause abnormal vibration in the gear transmission system or even interrupt the meshing of the gear pair, accelerate the fatigue damage of the gears, and cause premature gear failure. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and to propose a powder zinc diffusion furnace anti-skipping tooth device to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a device for preventing tooth skipping in a powder zinc infiltration furnace, comprising a platform, a furnace body on the platform, a furnace shaft at one end of the furnace body, a shaft gear fixedly connected to the end of the furnace shaft away from the furnace body, a fixed platform fixedly mounted on the top of the platform, a rotating shaft rotatably connected to the inner surface of the fixed platform, a drive gear fixedly connected to the end of the rotating shaft near the shaft gear, and the drive gear meshing with the shaft gear, a transmission connection mechanism for driving the furnace shaft to rotate on the platform, and an elastic clamping mechanism for preventing tooth skipping on the fixed platform.

[0006] Preferably, the transmission connection mechanism includes a motor fixedly mounted on the device platform, a drive wheel fixedly connected to the output end of the motor, and a belt slidably connected to the outer surface of the drive wheel. The transmission connection mechanism can synchronously drive the two sets of furnace shafts, so that the furnace shafts act on the corresponding furnace bodies respectively. The furnace body (i.e., the powder zinc diffusion furnace) is provided with two sets.

[0007] Preferably, the inner surface of the device platform is rotatably connected to a through shaft, one end of which is fixedly connected to a transmission wheel, and the outer surface of the transmission wheel is slidably connected to the inner side of the belt away from the drive wheel.

[0008] Preferably, a lower rotating wheel is fixedly connected to the end of the shaft away from the drive wheel, and a conveyor belt is slidably connected to the outer surface of the lower rotating wheel. An upper rotating wheel is fixedly connected to the end of the shaft away from the drive gear, and the outer surface of the upper rotating wheel is slidably connected to the inner side of the conveyor belt.

[0009] Preferably, the elastic clamping mechanism includes a slide block slidably connected to the inner side of the fixed platform, and the inner surface of the slide block is rotatably connected to the outer surface of the furnace shaft. A spring is fixedly connected to the top of the slide block. The elastic clamping mechanism can dynamically compensate for pressure and counteract the surging force, prevent the gears from disengaging, and achieve the effect of preventing gear skipping.

[0010] Preferably, a slide plate is slidably connected to the inner side of the fixed platform, and the bottom of the slide plate is fixedly connected to the top of the spring. A screw is threadedly connected to the top of the fixed platform, and the bottom of the screw is rotatably connected to the top of the slide plate. A knob is provided on the top of the screw.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The anti-gear skipping device for the powder zinc diffusion furnace can promptly offset the axial movement of gears due to pressure fluctuations caused by the rotational inertia of the furnace body, or due to sudden load changes or vibrations. This allows the gears to quickly return to a stable meshing state even if they are briefly disengaged from the drive gear. This effectively reduces the problem of gear skipping caused by the inability of gears to re-engage in time, providing a strong guarantee for the normal operation of the gear transmission system.

[0013] 2. The anti-gear skipping device for the powder zinc diffusion furnace uses an elastic element (i.e., a spring) that absorbs the vibration energy generated during gear transmission due to its own extension and contraction characteristics. While absorbing vibration, the extension and contraction of the spring can adjust the clamping force in real time, so that the gear pair always maintains a stable contact state, effectively eliminating gear meshing clearance. The elimination of gear meshing clearance further reduces the possibility of tooth skipping caused by excessive clearance, ensuring the smooth operation of the gear transmission system.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Please see Figure 1-4 A device for preventing tooth skipping in a powder zinc infiltration furnace includes a platform 1, a furnace body 2 on the platform 1, a furnace shaft 3 at one end of the furnace body 2, a shaft gear 4 fixedly connected to the end of the furnace shaft 3 away from the furnace body 2, a fixed platform 5 fixedly installed on the top of the platform 1, a rotating shaft 6 rotatably connected to the inner surface of the fixed platform 5, a drive gear 7 fixedly connected to the end of the rotating shaft 6 near the shaft gear 4, and the drive gear 7 meshing with the shaft gear 4, a transmission connection mechanism for driving the furnace shaft 3 to rotate is provided on the platform 1, and an elastic clamping mechanism for preventing tooth skipping is provided on the fixed platform 5.

[0021] Through the above technical solution, the device can drive two sets of furnace shafts 3 to rotate synchronously through the transmission connection mechanism during use, thereby acting on the corresponding furnace bodies 2 respectively. When the shaft gear 4 has an axial movement tendency due to sudden load change or vibration, the elastic clamping mechanism offsets the movement force through dynamic pressure compensation, preventing the shaft gear 4 from disengaging from the drive gear 7. That is, when the rotational inertia of the furnace body 2 causes pressure fluctuations between the gears, the extension and contraction characteristics of the spring 17 can adjust the clamping force in real time to maintain stable contact of the gear pair.

[0022] Specifically, the transmission connection mechanism includes a motor 8 fixedly installed on the device platform 1, a drive wheel 9 fixedly connected to the output end of the motor 8, and a belt 10 slidably connected to the outer surface of the drive wheel 9.

[0023] Through the above technical solution, the transmission system consisting of drive wheel 9, belt 10 and transmission wheel 12 has a transmission wrap angle greater than 120 degrees. This is to ensure that drive wheel 9 can rotate synchronously with transmission wheel 12 through belt 10 during rotation.

[0024] Specifically, a through shaft 11 is rotatably connected to the inner surface of the device platform 1, and a transmission wheel 12 is fixedly connected to one end of the through shaft 11. The outer surface of the transmission wheel 12 is slidably connected to the inner side of the belt 10 away from the drive wheel 9.

[0025] Through the above technical solution, the transmission wheel 12 is indirectly connected to the lower rotating wheel 13 through the through shaft 11, and the lower rotating wheel 13 will rotate synchronously during the rotation of the transmission wheel 12.

[0026] Specifically, a lower rotating wheel 13 is fixedly connected to the end of the shaft 11 away from the transmission wheel 12, and a conveyor belt 14 is slidably connected to the outer surface of the lower rotating wheel 13. An upper rotating wheel 15 is fixedly connected to the end of the shaft 6 away from the drive gear 7, and the outer surface of the upper rotating wheel 15 is slidably connected to the inner side of the conveyor belt 14.

[0027] With the above technical solution, the conveyor belt 14 is triangular in shape, with its three corners slidably connected to two upper rotating wheels 15 and one lower rotating wheel 13, respectively. That is, during the rotation of the lower rotating wheel 13, the transmission action of the conveyor belt 14 can ensure that the two sets of upper rotating wheels 15 rotate accordingly, and then drive the drive gear 7 to rotate synchronously through the rotating shaft 6.

[0028] Specifically, the elastic clamping mechanism includes a slide 16 that is slidably connected to the inside of the fixed platform 5, and the inner surface of the slide 16 is rotatably connected to the outer surface of the furnace shaft 3. A spring 17 is fixedly connected to the top of the slide 16.

[0029] Through the above technical solution, under the elastic action of the spring 17, it provides an elastic pressure on the slide block 16, which can ensure that the shaft gear 4 can quickly recover even if it skips teeth with the drive gear 7.

[0030] Specifically, a slide plate 18 is slidably connected to the inner side of the fixed platform 5, and the bottom of the slide plate 18 is fixedly connected to the top of the spring 17. A screw 19 is threadedly connected to the top of the fixed platform 5, and the bottom of the screw 19 is rotatably connected to the top of the slide plate 18. A knob 20 is provided on the top of the screw 19.

[0031] Through the above technical solution, turning the knob 20 can make the screw 19 gradually move down. During this time, the slide plate 18 will move down accordingly and compress the spring 17 to make it contract. At this time, the elastic pressure of the spring 17 on the slide block 16 is greater.

[0032] Working Principle: During operation, this device drives two sets of furnace shafts 3 via a transmission connection mechanism. First, the motor 8 is turned on to drive the drive wheel 9, which, under the transmission of the belt 10, causes the linkage drive wheel 12 to rotate synchronously. During rotation, the drive wheel 12 drives the lower rotating wheel 13 to rotate via the through shaft 11. Combined with the transmission of the conveyor belt 14, this drives the two sets of upper rotating shafts 6 to rotate, causing the corresponding drive gear 7 at the other end of the rotating shaft 6 to rotate. The drive gear 7, in turn, drives the meshing shaft gear 4 to rotate, ultimately rotating the furnace shaft 3 on the corresponding furnace body 2. When the rotational inertia of the furnace body 2 causes pressure fluctuations between the gears, i.e., when the shaft gear 4 experiences axial movement due to sudden load changes or vibration, the elastic clamping mechanism can compensate for the axial movement through dynamic pressure compensation, allowing the gear to quickly return to meshing even after disengaging from the drive gear 7. During this process, the spring... The telescopic characteristic of spring 17 allows for real-time adjustment of the clamping force, maintaining stable contact between the gear pairs. Furthermore, the elastic element (spring 17) absorbs vibration energy, eliminating gear meshing clearance and reducing tooth skipping caused by excessive clearance. Rotating knob 20 drives screw 19 to rotate, gradually lowering it and causing slide plate 18 to move synchronously downwards. During this process, slide plate 18, in conjunction with slide block 16, gradually compresses spring 17, increasing the elastic pressure exerted by spring 17 on slide block 16. This allows slide block 16 and furnace shaft 3 to apply varying degrees of clamping force to shaft gear 4. In actual production, different zinc diffusion process parameters, gear specifications, and load conditions can all affect the operating status of the gear transmission system. This adjustable clamping force design enables the device to adapt to different working conditions, ensuring stable operation of the gear transmission system under various conditions.
