Description

Technical Field

[0001] The utility model relates to a low-noise shock-absorbing gear and belongs to the technical field of gears. Background Art

[0002] Gears are mechanical elements with teeth on the rim that can continuously mesh to transmit motion and power. They are toothed mechanical parts that can mesh with each other. The diameter of the large gear is twice the diameter of the small gear. Gears are used in various occasions and machines.

[0003] Although the existing gears can be used for daily transmission operations, in actual use, in order to reduce their friction resistance and mechanical wear, they need to be lubricated during operation, and traditional mechanical gears need to apply lubricating oil to the gear teeth from time to time. However, this application method can only be performed when the gear is stopped. After the gear rotates, the applied lubricating oil quickly separates from the gear body due to the centrifugal force, so that the lubrication time is not long, and the lubrication effect is not good enough, and the use effect of the shock-absorbing gear is not good enough. In addition, the gears are meshed and connected. Since the gear bodies slide, the friction force when the gears are meshed is large, which makes the noise generated when the shock-absorbing gear is working large. Utility Model Content

[0026] Please refer again Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth specifically explaining that the outer surface of the oil storage rack 5 is rotatably connected to the inner wall of the wheel body 1, two oil outlet holes 8 penetrate the two sides of the oil storage tank 6, the two oil outlet holes 8 are connected to the two collecting holes 9 at the separated ends, and the two collecting holes 9 are connected to the two lubrication holes 10 at the separated ends. The connecting hole 7 penetrates the two sides of the bottom of the oil storage tank 6, and the oil filling hole 4 penetrates the upper side of the oil storage rack 5. The oil storage rack 5 is arranged in a circular ring shape. The connecting hole 7 can connect the bottom of the oil storage tank 6 to evenly distribute the lubricating oil on both sides of the oil storage tank 6.

[0027] Please refer again Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth mentioning that a rotating groove 11 is opened in the middle of each tooth body 2, a fixed shaft 12 is fixed in the middle of each rotating groove 11, a rotating wheel 13 is rotatably connected in the middle of each fixed shaft 12, both ends of each fixed shaft 12 are fixed in the middle of each rotating groove 11, the middle of each rotating wheel 13 is rotatably connected to the outer surface of each fixed shaft 12, and the outer surface of each rotating wheel 13 is rotatably connected to the inner wall of each rotating groove 11.

[0028] When the utility model is in use, first, the oil filling hole 4 of the wheel body 1 is placed on top and then placed vertically. The vertically placed oil filling hole 4 is now connected to the oil storage tank 6 of the oil storage rack 5, so that lubricating oil can be injected into the oil storage tank 6 from the oil filling hole 4. After the lubricating oil is filled, the mounting groove 3 of the wheel body 1 is connected to the connecting shaft of the connecting gear, and the wheel body 1 is driven to rotate by the connecting shaft, so that a plurality of tooth bodies 2 fixed to the side of the wheel body 1 rotate to mesh and drive other gears to rotate. At this time, the oil storage rack 5 rotatably connected to the wheel body 1 has a solid bottom and a hollow upper part, so that the solid position is always at the lowest point, so that the oil storage rack 5 is driven by the rotating wheel body 1 to perform a slight swing operation, and the swinging oil storage rack 5 relies on the two oil outlet holes 8 to discharge the lubricating oil outward. At this time, the collecting holes 9 opened on both sides of the rotating wheel body 1 are aligned with the oil outlet holes 8. At the moment, a small amount of lubricating oil will flow from the oil storage tank 6 into the collecting holes 9. The lubricating oil flowing into the collecting holes 9 is due to the rotation The centrifugal force generated by the rotating wheel body 1 causes a small amount of lubricating oil in the collecting hole 9 to be thrown out from the lubricating holes 10 opened in two of the gear bodies 2. The inclined lubricating holes 10 throw the lubricating oil onto the gear body 2 to lubricate the gear. The lubricating oil injected back and forth can lubricate the gear for a long time, achieve the effect of long-lasting lubrication, effectively prolong the duration of gear lubrication, and thus achieve the effect of improving the use effect of the shock-absorbing gear. At the same time, the wheel body 1 is driven to rotate through the connecting shaft, so that several gear bodies 2 fixed to the wheel body 1 rotate. When the rotating gear body 2 is meshed and connected with other gears, due to the mutual friction between the tooth body 2 and the tooth body 2 of other gears, the rotating wheel 13 rotatably connected to the tooth body 2 rotates under the stability of the fixed shaft 12 and the rotating groove 11, and sliding is changed to rotation to reduce friction, thereby achieving the effect of reducing friction, effectively reducing the friction between gears, thereby reducing the vibration generated by the gear, and thus achieving the effect of reducing the noise of the shock-absorbing gear.

[0029] Working principle: The wheel body 1 is driven to rotate through the connecting shaft, so that the wheel body 1 drives the oil storage rack 5 to shake, achieving the effect of long-lasting lubrication, effectively extending the lubrication time of the gear, and thus improving the use effect of the shock-absorbing gear. At the same time, the wheel body 1 is driven to rotate through the connecting shaft, so that the wheel body 1 drives the tooth body 2 to rotate, achieving the effect of reducing friction, effectively reducing the friction between gears, thereby reducing the vibration generated by the gear, and thus achieving the effect of reducing the noise of the shock-absorbing gear.
