Description

Technical Field

[0001] The present invention relates to the technical field of reducers, and more particularly to a reducer with a flexible wheel tooth shape. Background Art

[0002] The harmonic reducer is mainly composed of a wave generator, a flexible gear (flexible wheel), a rigid gear (rigid wheel), etc. The wave generator is arranged inside the flexible gear, and the flexible gear is arranged inside the rigid gear. The wave generator causes the flexible wheel to produce controllable elastic deformation, and the flexible wheel meshes with the rigid wheel to transmit motion and power.

[0003] When the flex spline and the rigid wheel of the harmonic reducer are meshing and transmitting, the flex spline will deform. The deformation of the flex spline will cause uneven force on the rigid wheel, making the parts of the rigid wheel with greater force prone to wear, thereby reducing the service life of the reducer.

[0004] To this end, the present invention provides a reducer with a flexible wheel tooth shape. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The present invention provides a speed reducer with a flexible wheel tooth shape, a wave launcher, a flexible wheel mechanism and a rigid wheel mechanism, wherein the outer wall of the wave launcher is meshed with the flexible wheel mechanism, and the outer side of the flexible wheel mechanism is meshed with the rigid wheel mechanism; The flexible wheel mechanism comprises a flexible wheel plate, the outer side of the flexible wheel plate is fixedly connected with flexible teeth, the upper end of the flexible teeth is provided with an inclined surface, and the rigid wheel mechanism comprises a rigid wheel plate, the inner wall of the rigid wheel plate is fixedly connected with rigid teeth.

[0007] Preferably, a plurality of first mounting holes are formed at the upper end of the rigid wheel plate, and first bolts are threadedly connected to inner walls of the first mounting holes.

[0008] Preferably, a ball guide block is inserted between the two balls, the lower end of the rigid wheel plate is slidably connected to a mounting ring, a plurality of first fixing holes are opened at the upper end of the mounting ring, and a protective ring is fixedly connected to the outer side of the mounting ring.

[0009] Preferably, the lower end of the flexible wheel plate is fixedly connected to a base, the base is provided with a plurality of second fixing holes, the second fixing holes penetrate the base, and the inner walls of the second fixing holes are threadedly connected with second bolts.

[0010] Preferably, the upper end of the base is slidably connected to a shell, and the shell includes a fixing ring slidably connected to the upper end of the base.

[0011] Preferably, a second mounting hole is opened at the upper end of the fixing ring, and the second mounting hole passes through the fixing ring. A supporting ring is fixedly connected to the inner wall of the fixing ring, and the width of the supporting ring is consistent with the width of the protective ring.

[0012] Preferably, the outer side of the shell is rotatably connected to a cooling mechanism, the cooling mechanism includes an annular water tank, the annular water tank is rotatably connected to the outer side of the fixing ring, the upper end of the annular water tank is fixedly connected to a tension spring, and the upper end of the tension spring is fixedly connected to a clamping plate.

[0013] Preferably, a cooling plate is fixedly connected to the inside of the annular water tank, one end of the cooling plate is located on the outside of the annular water tank, the outside of the annular water tank is fixedly connected to a limiting frame, the lower end of the clamping plate is located inside the limiting frame, the inner wall of the limiting frame is fixedly connected to a rotating shaft passing through the clamping plate, and the rotating shaft is rotatably connected to the clamping plate.

[0014] Preferably, a water inlet pipe is fixedly connected to the outer side of the annular water tank, and a plug is slidably connected to the inner wall of the water inlet pipe.

[0015] The beneficial effect of the present invention is that: in the reducer with a flexible wheel tooth shape described in the present invention, when the opening of the wave launcher mechanism inevitably expands due to specific operating requirements in daily work, the opening of the flexible wheel plate also expands outward accordingly. The inclined surface design on the flexible tooth can ensure that the inclined surface part of the upper end of the flexible tooth can smoothly form the same plane with the middle area of ​​the flexible tooth at the moment of expansion. Such a design not only promotes the smoothness of the flexible wheel plate during the expansion process, but more importantly, it ensures that the flexible tooth can maintain a full and tight meshing state with the rigid tooth. This fully meshing state greatly reduces the risk of wear, impact and even damage between teeth that may be caused by sudden deformation of the flexible wheel plate. In the long run, this design consideration not only significantly improves the working stability and reliability of the wave launcher mechanism and the entire flexible wheel mechanism, but also greatly extends the service life of the entire device.

[0016] The reducer with a flexible wheel tooth shape described in the present invention places the fixing ring securely on the upper end of the base to ensure that the two fit closely and are accurately positioned. The second bolt is inserted into the second fixing hole preset on the base and continues to extend into the corresponding second mounting hole on the fixing ring. The mounting ring is then placed in the already positioned fixing ring. This can effectively prevent the protective ring from shifting or deforming during use. Then, we accurately place the rigid wheel plate on the upper end of the mounting ring. When placing, ensure that the first mounting hole on the rigid wheel plate is completely aligned with the first fixing hole on the mounting ring. Then, the first bolt is passed through the first mounting hole on the rigid wheel plate and the first fixing hole on the mounting ring in turn, and then tightened. Through this step, we can firmly fix the mounting ring and the rigid wheel plate together, thereby forming a stable and easy-to-disassemble and install equipment structure. Such a design not only improves the stability and reliability of the equipment, but also greatly facilitates subsequent maintenance and maintenance work.

[0017] The reducer with a flexible wheel tooth shape described in the present invention pulls the plug out from the water inlet pipe, then transports water to the annular water tank through the water inlet pipe, and then plugs the plug into the water inlet pipe, and then pulls the clamping plate so that the clamping plate rotates under the action of the rotating shaft, and then puts the input shaft or the output shaft into the reducer, and then drives the clamping plate to reset under the reset action of the tension spring, so that the input shaft or the output shaft is clamped and fixed, when the input shaft or the output shaft rotates, the clamping plate is driven to rotate, thereby driving the annular water tank to rotate, so that the annular water tank cools the reducer, because the cooling plate 604 is designed to be inclined, when the annular water tank 601 rotates, it will drive the cooling plate 604 fixedly connected in the annular water tank 601 to rotate, so that the wind is sent to the reducer for air cooling, and the cooling plate 604 is made of aluminum alloy material, and when one end of the cooling plate 604 contacts the liquid in the annular water tank 601, it absorbs the heat in the liquid. Then, when the other end of the cooling plate contacts the air, it releases the absorbed heat into the air. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0021] Embodiment 1 like Figures 1 to 6 As shown, a reducer with a flexible gear tooth shape according to an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 , comprising a wave launcher 200, a flexible wheel mechanism 300 and a rigid wheel mechanism 400, wherein the outer wall of the wave launcher 200 is meshed with the flexible wheel mechanism 300, and the outer side of the flexible wheel mechanism 300 is meshed with the rigid wheel mechanism 400; The flexwheel mechanism 300 includes a flexwheel plate 301 , the outer side of which is fixedly connected with a flexible tooth 302 , and the upper end of the flexible tooth 302 is provided with an inclined surface. The rigid wheel mechanism 400 includes a rigid wheel plate 404 , the inner wall of which is fixedly connected with a rigid tooth 407 .

[0022] Specifically, when the opening of the wave launcher 200 inevitably expands due to specific operating requirements in daily work, the opening of the flexible wheel plate 301 also expands outward accordingly. The inclined surface design on the flexible tooth 302 can ensure that the inclined surface part of the upper end of the flexible tooth 302 can smoothly form the same plane with the middle area of ​​the flexible tooth 302 at the moment of expansion. Such a design not only promotes the smoothness of the flexible wheel plate 301 during the expansion process, but more importantly, it ensures that the flexible tooth 302 can maintain a full and tight meshing state with the rigid tooth 407. This fully meshing state greatly reduces the risk of wear, collision and even damage between teeth that may be caused by sudden deformation of the flexible wheel plate 301. In the long run, this design consideration not only significantly improves the working stability and reliability of the wave launcher 200 and the entire flexible wheel mechanism 300, but also greatly extends the service life of the entire device.

[0023] Please refer to Figure 4 , Figure 5 The upper end of the rigid wheel plate 404 is provided with a plurality of first mounting holes 405, the inner wall of the first mounting hole 405 is threadedly connected with a first bolt 406, the lower end of the rigid wheel plate 404 is slidably connected with a mounting ring 401, the upper end of the mounting ring 401 is provided with a plurality of first fixing holes 403, the outer side of the mounting ring 401 is fixedly connected with a protective ring 402, the lower end of the flexible wheel plate 301 is fixedly connected with a base 100, the base 100 is provided with a plurality of second fixing holes 101, and the second fixing holes 102 are fixedly connected with the base 100. 01 passes through the base 100, the inner wall of the second fixing hole 101 is threadedly connected with the second bolt 102, the upper end of the base 100 is slidably connected with the shell 500, the shell 500 includes a fixing ring 501 slidably connected to the upper end of the base 100, the upper end of the fixing ring 501 is provided with a second mounting hole 502, the second mounting hole 502 passes through the fixing ring 501, the inner wall of the fixing ring 501 is fixedly connected with a support ring 503, and the width of the support ring 503 is consistent with the width of the protective ring 402.

[0024] Specifically, first, we need to place the fixing ring 501 securely on the upper end of the base 100 to ensure that the two fit tightly and are positioned accurately. Insert the second bolt 102 through the preset second fixing hole 101 on the base 100, and continue to penetrate into the corresponding second mounting hole 502 on the fixing ring 501. Then place the mounting ring 401 into the already positioned fixing ring 501. This can effectively prevent the protective ring 402 from shifting or deforming during use. Then, we place the rigid wheel plate 404 precisely on the upper end of the mounting ring 401. When placing, ensure that the first mounting hole 405 on the rigid wheel plate 404 is completely aligned with the first fixing hole 403 on the mounting ring 401. Then pass the first bolt 406 through the first mounting hole 405 on the rigid wheel plate 404 and the first fixing hole 403 on the mounting ring 401 in turn, and then tighten them. Through this step, we can firmly fix the mounting ring 401 and the rigid wheel plate 404 together, thereby forming a stable equipment structure that is easy to disassemble and install. Such a design not only improves the stability and reliability of the equipment, but also greatly facilitates subsequent maintenance and care work.

[0025] Please refer to Figure 6 The outer side of the shell 500 is rotatably connected with a cooling mechanism 600, and the cooling mechanism 600 includes an annular water tank 601, which is rotatably connected to the outer side of the fixing ring 501, and a tension spring 602 is fixedly connected to the upper end of the annular water tank 601, and a clamping plate 603 is fixedly connected to the upper end of the tension spring 602, and a cooling plate 604 is fixedly connected to the inside of the annular water tank 601, and one end of the cooling plate 604 is located on the outer side of the annular water tank 601, and a limiting frame 605 is fixedly connected to the outer side of the annular water tank 601, and the lower end of the clamping plate 603 is located inside the limiting frame 605, and the inner wall of the limiting frame 605 is fixedly connected with a rotating shaft 606 that passes through the clamping plate 603, and the rotating shaft 606 is rotatably connected to the clamping plate 603, and a water inlet pipe 607 is fixedly connected to the outer side of the annular water tank 601, and a plug 608 is slidably connected to the inner wall of the water inlet pipe 607.

[0026] Specifically, the plug 608 is pulled out from the water inlet pipe 607, and then the water is transported to the annular water tank 601 through the water inlet pipe 607, and then the plug 608 is inserted into the water inlet pipe 607, and then the clamping plate 603 is pulled to rotate under the action of the rotating shaft 606, and then the input shaft or the output shaft is placed in the reducer, and then the clamping plate 603 is driven to reset under the reset action of the tension spring 602, so that the input shaft or the output shaft is clamped and fixed. When the input shaft or the output shaft rotates, , driving the clamping plate 603 to rotate, thereby driving the annular water tank 601 to rotate, so that the annular water tank 601 cools the reducer. Since the cooling plate 604 is designed to be inclined, the annular water tank 601 will drive the cooling plate 604 fixedly connected in the annular water tank 601 to rotate when it rotates, thereby guiding the wind to the reducer for air cooling. The cooling plate 604 is made of aluminum alloy material. When one end of the cooling plate 604 contacts the liquid in the annular water tank 601, it absorbs the heat in the liquid. Then, when the other end of the cooling plate contacts the air, it releases the absorbed heat into the air.

[0027] How it works In the initial state, we need to place the fixing ring 501 securely on the upper end of the base 100 to ensure that the two fit tightly and are positioned accurately. Insert the second bolt 102 through the preset second fixing hole 101 on the base 100, and continue to penetrate into the corresponding second mounting hole 502 on the fixing ring 501. Then place the mounting ring 401 into the already positioned fixing ring 501. This can effectively prevent the protective ring 402 from shifting or deforming during use. Then, we place the rigid wheel plate 404 precisely on the upper end of the mounting ring 401. When placing, ensure that the first mounting hole 405 on the rigid wheel plate 404 is completely aligned with the first fixing hole 403 on the mounting ring 401. Then pass the first bolt 406 through the first mounting hole 405 on the rigid wheel plate 404 and the first fixing hole 403 on the mounting ring 401 in turn, and then tighten them. Through this step, we can firmly fix the mounting ring 401 and the rigid wheel plate 404 together, thereby forming a stable equipment structure that is easy to disassemble and install. Such a design not only improves the stability and reliability of the equipment, but also greatly facilitates subsequent maintenance and servicing work. Pull the plug 608 out of the water inlet pipe 607, then transport the water to the annular water tank 601 through the water inlet pipe 607, and then plug the plug 608 into the water inlet pipe 607, and then pull the clamping plate 603 so that the clamping plate 603 rotates under the action of the rotating shaft 606, and then put the input shaft or output shaft into the reducer, and then drive the clamping plate 603 to reset under the reset action of the tension spring 602, so as to clamp the input shaft or output shaft. Fixed, when the input shaft or the output shaft rotates, the clamping plate 603 is driven to rotate, thereby driving the annular water tank 601 to rotate, so that the annular water tank 601 cools the reducer. Since the cooling plate 604 is designed to be inclined, the annular water tank 601 will drive the cooling plate 604 fixedly connected in the annular water tank 601 to rotate when the annular water tank 601 rotates, thereby guiding the wind to the reducer for air cooling, and the cooling plate 604 is made of aluminum alloy material. When one end of the cooling plate 604 contacts the liquid in the annular water tank 601, it absorbs the heat in the liquid. Then, when the other end of the cooling plate contacts the air, it releases the absorbed heat into the air. The inclined surface design on the flexible tooth 302 can ensure that the inclined surface part of the upper end of the flexible tooth 302 can smoothly form the same plane with the middle area of ​​the flexible tooth 302 at the moment of expansion. Such a design not only promotes the smoothness of the flex spline plate 301 during the expansion process, but more importantly, it ensures that the flexible teeth 302 can maintain a full and tight meshing state with the rigid teeth 407. This fully meshed state greatly reduces the risk of wear, collision and even damage between teeth that may be caused by sudden deformation of the flex spline plate 301. In the long run, such design considerations not only significantly improve the working stability and reliability of the wave launcher 200 and the entire flex spline mechanism 300, but also greatly extend the service life of the entire device.

[0028] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
