Abstract
Description
Technical Field
[0001] This utility model relates to the field of double-row toothed vibration damper technology, and in particular to a toothed ring limiting baffle for a double-row toothed vibration damper. Background Technology
[0002] A double-row toothed vibration damper is a device that reduces mechanical vibration by utilizing the principle of gear meshing. Its main structure consists of two arranged toothed rings, each with multiple tooth surfaces. Vibration energy is transmitted and absorbed through the meshing of the gears. When external impact or vibration acts on the damper, the meshing of the toothed rings generates friction and contact forces, effectively converting vibration energy into heat or dissipating it through elastic deformation, thus achieving vibration reduction. Compared to a single-row toothed structure, the double-row toothed structure has higher load-bearing capacity and vibration reduction efficiency, making it suitable for mechanical equipment requiring high vibration reduction, such as large machinery and transportation vehicles.
[0003] Currently, existing gear ring limiting baffles suffer from several drawbacks during use. Due to the lack of an effective limiting structure within the damper housing, the gear ring may experience excessive impact or displacement during operation, leading to positional deviation within the damper housing. This deviation directly affects the overall stability of the damper and can result in decreased vibration control effectiveness or even system failure. Furthermore, because the gear ring and limiting baffle employ a contact-type design, excessive friction can easily occur on the contact surface after prolonged use, causing wear or deformation of the limiting baffle and weakening the overall performance of the damper. This wear process is exacerbated, especially under high-intensity operating conditions, where frequent vibrations and impacts accelerate the process, rendering the limiting baffle unable to effectively control the gear ring's range of motion and ultimately reducing system stability.
[0004] Based on this, we propose a toothed ring limiting baffle for a double-row toothed vibration damper to solve the aforementioned problems. Utility Model Content
[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0006] Therefore, the purpose of this utility model is to provide a toothed ring limiting baffle for a double-row toothed vibration damper, which can solve the problem of wear or deformation caused by the lack of an effective limiting structure and excessive friction in the use of existing toothed ring limiting baffles, thereby improving the overall stability and performance of the vibration damper.

The gear ring limiting component includes a limiting baffle, one end of the limiting baffle is connected to an output shaft, and a first connecting flange is provided at the end of the limiting baffle away from the output shaft.

The second connecting flanges are structurally matched with the first connecting flanges, and the second connecting flanges and the first connecting flanges are fixedly connected.
[0009] Optionally, the damper housing has a damping cavity inside, which matches the damping gear ring structure. The damping cavity and the damping gear ring have a transition fit. The damper housing is also equipped with baffle connecting covers at both ends.
[0010] Optionally, the baffle connecting cover has a baffle adjustment groove inside, which matches the structure of the limiting baffle. The baffle adjustment groove and the limiting baffle are in transition fit, and sealing guide rings are respectively provided on both sides of the inner wall of the baffle adjustment groove.
[0011] Optionally, the limiting plate includes a first plate body, and a second plate body is connected to both sides of the first plate body. The second plate body and the sealing guide ring are made of the same material, both of which are made of engineering ceramics. Several sets of circumferentially distributed positioning pins are arranged around both sides of the first plate body.
[0012] Optionally, several sets of circumferentially distributed positioning holes are provided around the two sets of second discs. The positioning holes are matched with the positioning pin structure, and the positioning holes and positioning pins are in a snap-fit fit. Annular guide grooves are also provided on the outer sides of the two sets of second discs.

[0013] In summary, this utility model has at least one of the following beneficial effects:
[0014] 1.

The toothed ring limiting components include a limiting baffle, an output shaft, and a first connecting flange.

[0015] 2. The toothed ring limiting baffle designed in this scheme for the double-row toothed vibration damper effectively achieves a transition fit between the limiting baffle and the vibration damper housing through the structural design of the baffle connecting cover and the baffle adjusting groove. This avoids frictional contact between the limiting baffle and the double-row gears, reducing excessive wear and heat accumulation.

This optimized design ensures stable operation of the vibration damper during operation, improving the vibration damping effect and system reliability. This structural design effectively prevents failures caused by excessive impact, thereby enhancing the reliability and durability of the vibration damper under high load and high frequency operating conditions.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example: Refer to Figures 1 to 5 This utility model provides an embodiment of a gear ring limiting baffle for a double-row gear vibration damper, including a vibration damper housing 1. A double-row gear 2 is installed inside the vibration damper housing 1. Gear ring limiting components 3 are respectively provided at both ends of the vibration damper housing 1 near the double-row gear 2. Each gear ring limiting component 3 includes a limiting baffle 4. One end of the limiting baffle 4 is connected to an output shaft 5, and the end of the limiting baffle 4 away from the output shaft 5 is provided with a first connecting flange 6. The gear ring limiting baffle, through a structure that matches the positioning hole 17 with the positioning pin 16 and the snap-fit engagement between the positioning hole 17 and the positioning pin 16, allows for the disassembly, assembly, connection, maintenance, and replacement of the two sets of second disc bodies 15 equipped with the output shaft 5 and the first connecting flange 6, depending on the usage. This structural design improves... The equipment offers greater flexibility in the field of double-row gear vibration dampers, particularly in terms of maintenance and replacement. It provides a convenient disassembly and replacement method, avoiding excessive downtime due to equipment damage. The double-row gear 2 includes a central shaft 7, with damping gear rings 8 installed on the outer sides of both ends of the central shaft 7. Second connecting flanges 9 are also installed on both ends of the central shaft 7. The second connecting flanges 9 are structurally matched with the first connecting flange 6, and the second connecting flanges 9 and the first connecting flange 6 are fixedly connected. By adding second connecting flanges 9 to both ends of the central shaft 7, and by using a fixed connection between the second connecting flanges 9 and the first connecting flange 6, a firm connection between the damping gear rings 8 and the vibration damper housing 1 can be ensured, preventing loosening or displacement caused by high-frequency vibration and impact.
[0025] The damper housing 1 has a damping cavity 10 inside, which matches the structure of the damping gear ring 8. The damping cavity 10 and the damping gear ring 8 have a transition fit. Baffle connecting covers 11 are installed at both ends of the damper housing 1. By installing baffle connecting covers 11 at both ends of the damper housing 1, the limiting baffle 4 can be limited and connected to both ends of the damper housing 1, while preventing frictional contact between the limiting baffle 4 and the double-row gear 2. A baffle adjusting groove 12 is provided inside the baffle connecting cover 11. The baffle adjusting groove 12 matches the structure of the limiting baffle 4. The baffles 4 are in a transition fit, and sealing guide rings 13 are respectively provided on both sides of the inner wall of the baffle adjustment groove 12. By opening the baffle adjustment groove 12 inside the baffle connecting cover 11 and forming a transition fit between the baffle adjustment groove 12 and the limiting baffle 4, the limiting baffle 4 can be stably limited and connected inside the baffle connecting cover 11. Through this structural design, the limiting baffle 4 can not only be fixed in a predetermined position to prevent displacement caused by vibration or impact, but also maintain a moderate degree of flexibility in the movable connection with the baffle connecting cover 11, thereby effectively absorbing vibration energy and avoiding friction damage during the operation of the shock absorber.
[0026] The limiting plate 4 includes a first plate 14, with second plates 15 connected to both sides of the first plate 14. The second plates 15 are made of the same material as the sealing guide ring 13, both being made of engineering ceramic. Several sets of circumferentially arranged positioning pins 16 are provided around both sides of the first plate 14. The second plates 15, being made of the same material as the sealing guide ring 13, are also made of engineering ceramic, ensuring that the limiting plate 4 has excellent wear resistance and high load-bearing capacity. During the operation of the vibration damper, the first plate 14 and the second plate 15 can effectively withstand the impact and vibration loads generated by the damping gear ring 8, reducing wear and deformation, thereby extending the service life of the gear ring limiting component 3. Several sets of circumferentially arranged positioning holes 17 are provided around the two sets of second plates 15. The positioning holes 17 and positioning pins 16 are structurally matched, and the positioning holes 17 and positioning pins 16 are in a snap-fit fit. Annular guide grooves 18 are also provided on the outer side of the second disc 15. The annular guide grooves 18 are matched with the sealing guide ring 13. The annular guide grooves 18 and the sealing guide ring 13 are in sliding fit. Through the snap-fit structure design between the positioning hole 17 and the positioning pin 16, the second disc 15 can be firmly fixed and accurately positioned with the first disc 14 and the damper housing 1. At the same time, it can be disassembled, connected and repaired according to the usage of the second disc 15, which can improve the maintenance convenience and service life of the damper. Through the sliding fit design between the annular guide grooves 18 and the sealing guide ring 13, the limiting baffle 4 installed inside the baffle connecting cover 11 can be guided and limited on both sides, effectively preventing the limiting baffle 4 from shifting position when the double-row gear 2 is subjected to excessive impact or displacement, thereby ensuring the stable operation of the double-row gear damper under high load and high vibration conditions.
[0027] Working Principle: The gear ring limiting baffle for the double-row gear vibration damper designed in this scheme mainly consists of a vibration damper housing 1, double-row gears 2, and a gear ring limiting component 3. The gear ring limiting component 3 includes a limiting baffle 4, an output shaft 5, and a first connecting flange 6. The limiting baffle 4 is structurally matched with the positioning pin 16 through the positioning hole 17, and the positioning hole 17 and the positioning pin 16 adopt a snap-fit structure design. According to the usage, the two sets of second disc bodies 15 with the output shaft 5 and the first connecting flange 6 can be disassembled, connected, repaired, and replaced. This design improves the flexibility and maintainability of the equipment in the field of double-row gear vibration damper technology, facilitates necessary maintenance and replacement during operation, and ensures the long-term stability of the equipment.
[0028] The double-row gear damper design in this scheme uses a gear ring limiting baffle. This is achieved by adding baffle connecting covers 11 to both ends of the damper housing 1, and a baffle adjusting groove 12 inside the baffle connecting cover 11. Because the baffle adjusting groove 12 is structurally compatible with the limiting baffle 4, and the baffle adjusting groove 12 and the limiting baffle 4 have a transition fit, this design allows the limiting baffle 4, which is connected to both ends of the double-row gear 2, to act as an isolation device, preventing frictional contact between the limiting baffle 4 and the double-row gear 2. This is achieved by dividing the inner wall of the baffle adjusting groove 12 on both sides... The separately opened sealing guide ring 13 and the annular guide groove 18 opened on one side of the two sets of second discs 15, because the annular guide groove 18 and the sealing guide ring 13 are structurally matched and have a sliding fit, further enhance the stability of the limiting plate 4. This design can effectively prevent the limiting plate 4 from shifting position when the double-row gear 2 is subjected to excessive impact or displacement, thereby ensuring the operational stability of the double-row gear vibration damper and avoiding the decrease in vibration control effect or system failure caused by the shift.
