Description

Technical Field

[0001] The utility model relates to the technical field of gears, and more specifically, to a damping gear. Background Art

[0002] The shock-absorbing gear is a mechanical device that can reduce vibration and noise. Its main working principle is to absorb energy through the deformation of elastic materials, thereby reducing the vibration and noise transmitted to the mechanical system.

[0003] The Chinese invention patent with application number 202311871509.9 discloses a shock-absorbing gear and a vehicle, in which the gear is divided into a gear ring and a gear shaft, with a clearance fit between the two, and a spring is provided to support the clearance surface, so that when the gear is subjected to a large tangential force, it can be buffered by the spring, reducing the impact on the mounting shaft. However, the gear will heat up seriously during long-term operation, and thermal expansion will cause the fitting clearance to decrease, that is, the deformation margin is reduced, thereby affecting the shock-absorbing ability. Utility Model Content

[0007] The utility model is further configured as follows: the seismic isolation ring includes two fixing rings, the two fixing rings are respectively arranged at both ends of the seismic isolation ring, a layer adjacent to the fixing rings is a rubber ring, and a clearance is arranged between the outer ring of the rubber ring and the connecting plate and the inner ring of the gear body.

[0008] The utility model is further configured as follows: a plurality of lead cores are connected through all the rubber rings and the connecting plates, the lead cores are evenly distributed along the circumference, the axes of the lead cores are parallel to the axis of the gear body, and the two ends of the lead cores extend into corresponding fixing rings respectively.

[0009] The utility model is further configured as follows: the fixing ring, the rubber ring and the connecting plate are glued to each other.

[0010] The utility model is further configured as follows: a plurality of latching teeth are evenly arranged on the outer ring surface of the fixing ring, and the latching teeth are latched with the gear body.

[0011] The utility model is further configured as follows: a key groove is commonly provided on the inner ring surface of each layer of the seismic isolation ring.

[0012] The advantages of the utility model are:

[0013] 1. An isolation ring is arranged between the gear body and the preset rotating shaft. The isolation ring is a layered structure. The two ends of the isolation ring are fixed rings connected to the gear body through latch teeth. Between the two fixed rings are rubber rings and connecting plates arranged alternately. The rubber ring provides a deformation margin for the isolation ring, which can achieve shock absorption when the gear body is subjected to loads in all directions. The rubber has good heat resistance, is less affected by temperature, and has a stable shock absorption function.

[0014] 2. A number of lead cores are inserted axially in the isolation ring. When the force on each point of the gear body is uneven, the plastic deformation of the hysteresis damping produced by the lead core can absorb energy, thereby improving the isolation ring's ability to withstand tangential forces and improving the shock absorption effect.

The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0021] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually used in reference to the directions shown in the drawings, or in reference to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually used in reference to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0022] See also Figure 1-3 , the utility model provides the following technical solutions:

[0023] A shock-absorbing gear comprises a gear body 1, an inner ring of the gear body 1 is provided with a seismic isolation ring 2, the seismic isolation ring 2 is a layered structure, each layer of the seismic isolation ring 2 is perpendicular to the axis of the gear body 1, the seismic isolation ring 2 comprises a plurality of rubber rings 22 and a plurality of connecting plates 23, the plurality of rubber rings 22 and the plurality of connecting plates 23 are alternately arranged, a key groove 4 is commonly provided on the inner ring surface of each layer of the seismic isolation ring 2, the rubber ring 22 has good heat resistance, good durability, good resistance to low-cycle fatigue, resistance to hot air aging, resistance to ozone aging, acid resistance, and water resistance, can maintain good deformation performance under various working conditions, is not easily affected by temperature rise during operation, and has relatively stable seismic resistance.

[0024] The seismic isolation ring 2 includes two fixed rings 21, which are respectively arranged at both ends of the seismic isolation ring 2. A number of latch teeth 3 are evenly arranged on the outer ring surface of the fixed ring 21, and the latch teeth 3 are mutually engaged with the gear body 1. The layer adjacent to the fixed ring 21 is a rubber ring 22. A clearance 6 is arranged between the outer ring of the rubber ring 22 and the connecting plate 23 and the inner ring of the gear body 1. The fixed ring 21, the rubber ring 22 and the connecting plate 23 are glued to each other. The rubber ring 22 can be deformed in all directions, that is, when the gear body 1 is impacted in all directions, the rubber ring 22 can provide buffering, and its shock absorption ability is relatively comprehensive.

[0025] A plurality of lead cores 5 are connected and penetrated through all rubber rings 22 and connecting plates 23. The lead cores 5 are evenly distributed along the circumferential direction. The axis of the lead core 5 is parallel to the axis of the gear body 1. Both ends of the lead core 5 extend into the corresponding fixing ring 21 respectively. When the force on each point on the gear body 1 is uneven, the layered structure of the seismic isolation ring 2 is prone to twisting, thereby driving the lead core 5 to undergo plastic deformation and absorb the torsion between the layers, thereby avoiding stratification and improving the shock absorption effect. After the impact stops, the rubber ring 22 is reset and drives the lead core 5 to recover at the same time.

[0026] Specifically, an isolation ring 2 is arranged between the gear body 1 and the preset rotating shaft. The isolation ring 2 is a layered structure. Both ends of the isolation ring 2 are fixed rings 21 connected to the gear body 1 through the latch teeth 3. Between the two fixed rings 2 are rubber rings 22 and connecting plates 23 arranged alternately. The rubber rings 22 provide a deformation margin for the isolation ring 2, and can achieve shock absorption when the gear body 1 is subjected to loads in all directions. The rubber has good heat resistance, is less affected by temperature, and has a stable shock absorption function.

[0027] A plurality of lead cores 5 are inserted axially in the isolation ring 2. When the forces at various points of the gear body 1 are uneven, the plastic deformation of the hysteresis damping produced by the lead cores 5 can absorb energy, thereby improving the isolation ring 2's ability to withstand tangential forces and improving the shock absorption effect.
