Description

Technical Field

[0001] The utility model relates to the technical field of gears, in particular to a high-strength and stable gear. Background Art

[0002] Gears are wheel-shaped mechanical parts that transmit torque through meshing teeth. By connecting with other toothed mechanical parts (such as another gear, a rack, or a worm), gears can achieve functions such as varying speed and torque, changing the direction of motion, and altering the form of movement. Gear mechanisms are widely used in industrial products due to their high transmission efficiency, precise transmission ratios, and wide power range. When gear teeth interlock, one gear rotates the other, transmitting power. Separating the two gears allows chains, tracks, or belts to be used to drive the gears on both sides, transmitting power.

[0003] In the prior art, the working environment of some gears is poor, such as external dust particles, metal particles generated by gear friction, or metal scraps during processing. When these impurities fall into the gear tooth grooves, it will cause the gears to mesh with each other and rotate, which will easily cause the scraps and impurities to further rub against the gears in the tooth grooves, thereby accelerating the wear of the gears and affecting the service life of the gears. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a high-strength and stable gear so as to solve the technical problems mentioned in the above background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A high-strength and stable gear comprises a gear body, wherein airbags are fixedly connected to the tooth grooves of the gear body, an exhaust hole is provided on the side of the gear, an air outlet hole is provided on the side of the airbag close to the axis of the gear body, a sealing plate is connected to the side of the exhaust hole close to the outside of the gear body, a ventilation pipe is connected to the side of the sealing plate away from the exhaust hole, the end of the ventilation pipe extends to the corresponding tooth groove side, the end of the ventilation pipe is connected to a flaring plate, and a reset part is provided on the side of the airbag close to the axis of the gear body.

[0007] In a preferred example, the present invention can be further configured as follows: the vent pipe is arranged in a U shape, and a gap is left between the side of the flared plate away from the vent pipe and the gear body.

[0008] In a preferred example, the present invention can be further configured as follows: the airbag is made of rubber or silicone material, and the exhaust hole is arranged in a rectangular shape.

[0009] In a preferred example, the present invention can be further configured as follows: the reset member includes a lumen, the lumen is inserted into the inner wall of the tooth groove corresponding to the gear body, a reset rod is slidably connected in the lumen, and the end of the reset rod extends into the airbag.

[0010] In a preferred example, the present invention can be further configured as follows: the outer peripheral side of the reset rod and the side of the airbag close to the axis of the gear body are provided with a dynamic seal.

[0011] In summary, the present invention has at least one of the following beneficial technical effects:

[0012] 1. This high-strength and stable gear can squeeze the airbag when the gear body is in continuous meshing with the corresponding gear, thereby quickly blowing air to the tooth groove of the gear body that is about to mesh. In combination with the centrifugal force of the gear body, dust, impurities and metal particles in the tooth groove of the gear body are separated from the tooth groove, thereby reducing the wear of the gear body when meshing with the gear and extending the service life of the gear body.

[0013] 2. This high-strength and stable gear has an airbag made of rubber or silicone, which allows the airbag to reset itself and has high toughness, improving stability during use. The vent hole is rectangular, so that the vent hole can be aligned with the side of the airbag close to the axis of the gear body. When the airbag is squeezed, air can quickly enter the vent hole, thereby facilitating the removal of impurities in the gear body and tooth grooves.

[0014] 3. This high-strength and stable gear is provided with a cavity tube and a reset rod. When the airbag is squeezed, the reset rod will be pushed and enter the cavity tube. The cavity tube and the reset rod are set in a dynamic seal. Therefore, when the reset rod enters the cavity tube, the air pressure in the cavity tube increases. After the gear teeth disengage the tooth grooves in the gear body, the air pressure in the cavity tube will quickly push the reset rod to reset, so that the reset rod can push up the airbag, and the airbag is quickly filled with gas through the exhaust hole, the outlet hole and the ventilation tube. This allows the airbag to be quickly inflated under the high-speed rotation of the gear.

[0015] 4. This high-strength and stable gear is provided with a dynamic seal between the outer peripheral side of the reset rod and the side of the airbag close to the axis of the gear body. When the airbag is squeezed, the reset rod passes through the side of the airbag close to the axis of the gear body, thereby enabling the reset rod to slide at this position and preventing air leakage when the reset rod slides in the airbag.

[0021] The present invention will be described in further detail below with reference to the accompanying drawings.

[0022] Example:

[0023] Reference Figure 1-Figure 3 The utility model discloses a high-strength and stable gear, including a gear body 1, wherein an airbag 2 is fixedly connected to the tooth groove of the gear body 1, an exhaust hole 3 is opened on the side of the gear, and an air outlet hole 4 is opened on the side of the airbag 2 close to the axis of the gear body 1, and the exhaust hole 3 is connected to a sealing plate 5 on the side close to the outside of the gear body 1, and a ventilation pipe 6 is connected to the side of the sealing plate 5 away from the exhaust hole 3, and the end of the ventilation pipe 6 extends to the corresponding tooth groove side, and the end of the ventilation pipe 6 is connected to a flaring plate 7, and a reset part 8 is provided on the side of the airbag 2 close to the axis of the gear body 1.

[0024] In this embodiment, when in use, the gear body 1 will mesh with the corresponding gear. When the gear body 1 meshes with the corresponding gear, the teeth of the gear will be inserted into the tooth groove of the gear body 1, so that the teeth of the gear squeeze the airbag 2. After the gear is meshed with the gear body 1, the teeth of the gear are inserted into the tooth groove on the gear body 1, which just completely squeezes the airbag 2, thereby allowing the air in the airbag 2 to quickly enter the exhaust hole 3 from the air outlet 4, and then the air flow will enter the ventilation pipe 6 from the exhaust hole 3, and enter the expansion plate 7 from the outlet end of the ventilation pipe 6, and finally be ejected through the expansion plate 7, thereby blowing air into the tooth groove of the gear body 1 that is about to mesh, blowing out dust particles or metal particles in the tooth groove that is about to mesh, and then combined with the centrifugal force when the gear rotates, reducing the residual impurities in the gear body 1, thereby slowing down the wear of the gear body 1 during use, and improving the service life of the gear body 1 during use.

[0025] In a further preferred embodiment of the present invention, Figure 3 As shown, the vent pipe 6 is arranged in a U shape, and a gap is left between the side of the flared plate 7 away from the vent pipe 6 and the gear body 1 .

[0026] In this embodiment, the vent pipe 6 is U-shaped, and a gap is left between the side of the flared plate 7 away from the vent pipe 6 and the gear body 1, thereby avoiding friction between the gear teeth and the flared plate 7 when the gear is engaged with the gear body 1, avoiding damage to the flared plate 7 due to long-term use, and improving the service life of the flared plate 7.

[0027] In a further preferred embodiment of the present invention, Figure 3 As shown, the airbag 2 is made of rubber or silicone material, and the exhaust hole 3 is arranged in a rectangular shape.

[0028] In this embodiment, the airbag 2 is made of rubber or silicone material, so that the airbag 2 itself has the function of resetting and has high toughness, which improves stability during use. The exhaust hole 3 is arranged in a rectangular shape, so that the exhaust hole 3 can be fitted with the side of the airbag 2 close to the axis of the gear body 1, so that when the airbag 2 is squeezed, the air flow can quickly enter the exhaust hole 3, so as to facilitate the cleaning of impurities in the tooth grooves in the gear body 1.

[0029] In a further preferred embodiment of the present invention, Figure 2-3 As shown, the reset member 8 includes a lumen 9, which is inserted into the inner wall of the tooth groove corresponding to the gear body 1. A reset rod 10 is slidably connected in the lumen 9, and the end of the reset rod 10 extends into the airbag 2.

[0030] In this embodiment, the cavity 9 and the reset rod 10 are set, and after the airbag 2 is squeezed, the reset rod 10 will be pushed, and the reset rod 10 will enter the cavity 9. The cavity 9 and the reset rod 10 are dynamically sealed. Therefore, when the reset rod 10 enters the cavity 9, the air pressure in the cavity 9 increases. After the teeth of the gear disengage from the tooth grooves in the gear body 1, the air pressure in the cavity 9 will quickly push the reset rod 10 to reset, so that the reset rod 10 can lift the airbag 2, so that the airbag 2 is quickly filled with gas through the cooperation of the exhaust hole 3, the outlet hole 4 and the ventilation tube 6, so that the airbag 2 can be quickly inflated under the high-speed rotation of the gear.

[0031] In a further preferred embodiment of the present invention, Figure 3 As shown, the outer peripheral side of the reset rod 10 and the side of the airbag 2 close to the axis of the gear body 1 are dynamically sealed.

[0032] In this embodiment, the outer peripheral side of the reset rod 10 and the side of the airbag 2 close to the axis of the gear body 1 are dynamically sealed, so that after the airbag 2 is squeezed, the reset rod 10 passes through the side of the airbag 2 close to the axis of the gear body 1, thereby allowing the reset rod 10 to slide at this position, while preventing air leakage when the reset rod 10 slides in the airbag 2.

[0033] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
