Description

Technical Field

[0001] The utility model relates to a high-speed and stable damping gear, belonging to the technical field of gears. Background Art

[0002] Gears refer to mechanical components with teeth on the wheel rim that can continuously mesh to transmit motion and power. They have the characteristics of a wide power transmission range and high transmission efficiency. Currently, the main transmission components of most mechanical complete sets of equipment are gear transmissions. However, during the use of gears, vibrations are inevitable due to factors such as changes in speed and interactions between meshing gears.

[0003] The patent document publication number for comparison is: "A shock-absorbing gear of CN217401639U, comprising a gear body, wherein an outer arc-shaped slot is equidistantly provided on the edge of one end of the gear body, an inner arc-shaped slot is equidistantly provided in the middle of one end of the gear body, a No. 1 fixing screw is symmetrically provided at one end of the inner wall of the outer arc-shaped slot, and a No. 2 fixing screw is symmetrically provided at one end of the inner wall of the inner arc-shaped slot. Through the coordinated use of the outer arc-shaped slot, the No. 1 fixing screw, the No. 1 clamping hole, the outer arc-shaped clamping plate, the No. 1 limiting clamping hole and the fixing nut, the installation of the No. 1 shock-absorbing strip can be limited, and through the coordinated use of the inner arc-shaped slot, the No. 2 fixing screw, the No. 2 clamping hole, the inner arc-shaped clamping plate, the No. 2 limiting clamping hole and the fixing nut, the installation of the No. 2 shock-absorbing strip can be limited, which is beneficial to improve the installation stability of the No. 1 shock-absorbing strip and the No. 2 shock-absorbing strip, and facilitates the stable use of the No. 1 shock-absorbing strip and the No. 2 shock-absorbing strip".

[0004] The above patent still has the following problems in actual use: although the patent can be used for daily use, in the actual installation process, each rubber shock-absorbing strip requires two bolts to be tightened, and the staff needs to screw multiple bolts during installation and disassembly, which brings inconvenience to the staff and makes the shock-absorbing gear less convenient to use. In addition, since the gear is solid, the mass of the gear itself is large, and the inertia generated by the rotation of the gear is large. If only rubber shock-absorbing strips are used for shock-absorbing treatment, the gear is still prone to vibration due to the large inertia when running at high speed, which makes the shock-absorbing gear less stable in use.

[0025] The embodiment of the utility model provides a shock-absorbing gear that operates stably at high speed.

[0026] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , including a wheel body 1, which cooperates with a tooth body 2 to perform a transmission function. A tooth body 2 is fixed on the side of the wheel body 1, and a mounting groove 3 is opened in the middle of the wheel body 1. The mounting groove 3 is used to install the connecting shaft to drive the gear to rotate; placement grooves 4 are opened on both sides of the wheel body 1 near the center position, and the placement grooves 4 are used to place rubber shock-absorbing rings 5. Rubber shock-absorbing rings 5 ​​are arranged on the inner wall of the placement grooves 4, and a plurality of limiting grooves 6 are opened on the inner side of each placement groove 4. A connecting structure is arranged on the inner wall of each limiting groove 6. The connecting structure includes a limiting frame 7, and a resistance rod 8 is fixed in the middle of each limiting frame 7. A stabilizing hole 9 is opened on the side of each limiting groove 6 away from the placement groove 4.

[0027] Please refer again Figure 1 , Figure 2 , Figure 3 and Figure 4It is worth specifying that the outer surface of each resistance rod 8 is slidably connected to the inner wall of each stabilizing hole 9, the outer surface of each limiting frame 7 is slidably connected to the inner wall of each limiting groove 6, each limiting groove 6 is connected to the mounting groove 3 through each stabilizing hole 9, the outer surface of each limiting frame 7 is in contact with the outer surface of the rubber shock-absorbing ring 5, each limiting frame 7 is arranged in an arc shape, several limiting frames 7 are distributed in a ring shape, and the separated ends of several resistance rods 8 are fixed on the close sides of several limiting frames 7.

[0028] Please refer again Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth specifying that the outer surfaces of the two rubber shock-absorbing rings 5 ​​are in contact with the inner walls of the two placement grooves 4, three through grooves 10 are opened in the middle of the wheel body 1 near the edge, and a plurality of sound-absorbing holes 11 are opened in the middle of the wheel body 1 near the edge. The three through grooves 10 are distributed in a ring shape, wherein a plurality of sound-absorbing holes 11 are opened between two adjacent through grooves 10, and a plurality of sound-absorbing holes 11 are distributed in a ring shape. The three through grooves 10 penetrate the middle of the wheel body 1, and a plurality of sound-absorbing holes 11 penetrate the middle of the wheel body 1.

[0029] When the utility model is in use, first, the connecting shaft of the gear installation is passed through the installation groove 3, and the contact rod 8 is squeezed by the connecting shaft to perform the moving operation, so that the contact rods 8 can slide in the opposite direction under the stability of the plurality of stabilizing holes 9, and the plurality of reversely sliding contact rods 8 drive the plurality of fixed limiting frames 7 to move in the opposite direction under the limitation of the inner walls of the plurality of limiting grooves 6, and the plurality of reversely moving limiting frames 7 limit the rubber shock-absorbing ring 5 placed in the placement groove 4 to fix the position of the rubber shock-absorbing ring 5, thereby achieving the effect of convenient fixing, without the need for the staff to screw a plurality of bolts for the tightening and installation operation, which brings convenience to the staff's use, thereby achieving the effect of improving the convenience of using the shock-absorbing gear, and at the same time, by placing the rubber shock-absorbing ring 5 in the placement groove 4, the gear drives the rubber when rotating. The rubber damping ring 5 rotates in the placement groove 4. When the gear is vibrated, the vibration of the gear will be transmitted to the rubber damping ring 5. Since the rubber damping ring 5 is arranged near the center of the gear, there is a time difference in the transmission of the vibration. Relying on this time difference, the vibration direction of the rubber damping ring 5 and the gear will be opposite, thereby reducing the vibration. In addition, the three through grooves 10 opened in the middle of the wheel body 1 can reduce the overall mass of the gear. The reduced mass leads to a reduction in its inertia. The reduced inertia reduces the vibration. In addition, the sound-absorbing holes 11 opened can disperse the volume generated during the rotation of the gear to avoid the sound affecting the gear, achieve a full damping effect, avoid vibration when the gear runs at high speed, and thus achieve the effect of improving the stability of the damping gear.

[0030] Working principle: by squeezing the contact rod 8 through the connecting shaft to move the operation, the contact rod 8 drives the limit frame 7 to limit the rubber shock-absorbing ring 5, thereby achieving a convenient fixation effect. There is no need for the staff to tighten multiple bolts for installation operations, which brings convenience to the staff and thus improves the convenience of using the shock-absorbing gear. At the same time, by placing the rubber shock-absorbing ring 5 in the placement groove 4, the rubber shock-absorbing ring 5 cooperates with the through groove 10 and the sound-absorbing hole 11 to achieve a sufficient shock-absorbing effect, avoid vibration when the gear runs at high speed, and thus improve the stability of the shock-absorbing gear.

[0031] Please refer again Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth to explain in detail that the two rubber shock absorbing rings 5 ​​are arranged opposite to each other, the two placement grooves 4 are opened opposite to each other, and each rubber shock absorbing ring 5 is arranged in a ring shape.
