Description
Technical Field
[0001] This utility model relates to the field of gear technology, specifically a stable steering gear. Background Technology
[0002] A gear is a mechanical component that transmits motion and power through continuous meshing of gears on its rim. Gears have been used in transmission for a long time. In the late 19th century, the principle of gear cutting and the emergence of special machine tools and cutting tools for gear cutting based on this principle were developed. With the development of production, the smoothness of gear operation has become a focus.
[0003] In existing technology, a cutting machine is used to cut a whole steel plate into a complete gear for installation on the steering gear, resulting in a gear with greater overall strength.
[0004] However, existing steering gears are prone to vibration and wear during operation due to complex and variable loads. Vibration not only generates noise and affects the driving experience, but also leads to a decrease in the transmission accuracy of the gears. Utility Model Content
[0005] In view of the shortcomings of the existing technology, this utility model provides a stable steering gear, which solves the problem that existing steering gears are prone to vibration and wear during operation due to complex and variable loads. Vibration not only generates noise and affects the driving experience, but also leads to a decrease in the transmission accuracy of the gear.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a stable steering gear, including a wheel disk, the outer wall of the wheel disk is provided with teeth, the ends of the teeth are provided with transition surfaces, the outer wall of the wheel disk is provided with side grooves, the inner wall of the side grooves is fixedly connected with bosses, the outer wall of the teeth is provided with a wear-resistant layer, and the outer wall of the wheel disk is provided with a noise-reducing coating.
[0007] Preferably, the inner wall of the boss is provided with a keyway, and a rotating shaft is inserted into the inner wall of the keyway.
[0008] Preferably, the inner wall of the side groove is adhered with sound-absorbing cotton, and the inner wall of the sound-absorbing cotton is sleeved on the outer wall of the boss.
[0009] Preferably, the outer wall of the side groove is provided with a placement groove, and an oil-soaked sponge is inserted into the inner wall of the placement groove.
[0010] Preferably, the outer wall of the boss is provided with a reinforcing rib, and the outer wall of the reinforcing rib is fixedly connected to the inner wall of the side groove.
[0011] Preferably, the inner wall of the boss is provided with a mounting groove, and the inner wall of the mounting groove is rotatably connected to a locking block by a pin. The outer wall of the locking block is inserted into the outer wall of the rotating shaft. A counterweight is fixedly connected to one end of the locking block that extends into the mounting groove. The outer wall of the counterweight abuts against a spring, and the outer wall of the spring is fixedly connected to the inner wall of the mounting groove.
[0012] This utility model provides a stable steering gear. It offers the following advantages: The stable steering gear, through the cooperation of the wheel disc, teeth, and wear-resistant layer, reduces impact and friction during meshing by setting the top of the teeth as a transition surface, thus lowering wear. Simultaneously, a wear-resistant layer is applied to the outer wall of the teeth, improving their wear resistance. Furthermore, a noise-reducing coating is applied to the outer wall of the wheel disc, reducing noise during gear rotation. This solves the problem of vibration and wear easily occurring under complex and variable loads. Vibration not only generates noise, affecting the driving experience, but also leads to a decrease in gear transmission accuracy.
[0013] By combining the placement groove, the wheel, and the placement groove, a placement groove is opened inside the gear. After the oil-soaked sponge absorbs the grease, it is placed in the placement groove on the outer wall of the gear, so as to achieve continuous lubrication of the rotating parts of the gear, reduce wear, extend service life, and solve the problem that the existing gears are not strong enough under different load capacities and are prone to breakage.

[0020] 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.
[0021] Existing steering gears are prone to vibration and wear during operation due to complex and variable loads. Vibration not only generates noise and affects the driving experience, but also leads to a decrease in the transmission accuracy of the gears.
[0022] In view of this, the present invention provides a stable steering gear, which solves the problem that existing steering gears are prone to vibration and wear during operation due to complex and variable loads. Vibration not only generates noise and affects the driving experience, but also leads to a decrease in the transmission accuracy of the gear.
[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process.
[0024] Example 1: By Figure 1-5 It is known that a stable steering gear includes a wheel 1, the outer wall of the wheel 1 is provided with teeth 2, the end of the teeth 2 is provided with a transition surface 13, the outer wall of the wheel 1 is provided with a side groove 3, the inner wall of the side groove 3 is fixedly connected with a boss 4, the outer wall of the teeth 2 is provided with a wear-resistant layer 11, and the outer wall of the wheel 1 is provided with a noise-reducing coating 12.
[0025] In the specific implementation process, it is worth noting that several teeth 2 are provided on the outer wall of the wheel 1, and the ends of the teeth 2 are set as arc-shaped transition surfaces 13. This can reduce the impact and friction of the teeth during meshing, reduce the degree of wear, and the provided boss 4 can increase the axial stability of the gear, reduce the axial movement of the gear during rotation, and extend the service life of the gear. Laser hardening treatment is performed on the outer wall surface of the teeth 2 and the transition surface 13 to form a high-hardness wear-resistant layer 11; or a chemical coating process is used to coat a layer of wear-resistant alloy film to enhance the wear resistance and fatigue strength of the teeth 2 and extend the service life of the teeth 2. In addition, an elastic noise-reducing coating 12 is sprayed on the outer wall surface of the wheel 1 to reduce the noise generated during gear rotation and improve driving comfort.
[0026] Furthermore, a keyway 7 is provided on the inner wall of the boss 4, and a rotating shaft 6 is inserted into the inner wall of the keyway 7.
[0027] In the specific implementation process, it is worth noting that the keyway 7 is used to fix the rotating shaft 6 to ensure the stability of the gear rotation;
[0028] Furthermore, sound-absorbing cotton 8 is adhered to the inner wall of the side groove 3, and the inner wall of the sound-absorbing cotton 8 is sleeved on the outer wall of the boss 4.
[0029] In the specific implementation process, it is worth noting that the sound-absorbing cotton 8 is made of polyester fiber sound-absorbing cotton and is glued to the outer wall of the wheel 1, which can absorb the noise generated by the rotation of the gear.
[0030] Example 2: From Figure 1-5 It can be seen that the outer wall of the side groove 3 is provided with a placement groove 10, and an oil-soaked sponge 9 is inserted into the inner wall of the placement groove 10.
[0031] In the specific implementation process, it is worth noting that the front and rear openings of the placement groove 10 are in a constricted shape, and the cavity inside the placement groove 10 is relatively large. This makes it stable when placing the oil-soaked sponge 9, and the oil-soaked sponge 9 continuously lubricates the rotating parts of the gear, reducing wear and extending service life.
[0032] Furthermore, the outer wall of the boss 4 is provided with a reinforcing rib 5, and the outer wall of the reinforcing rib 5 is fixedly connected to the inner wall of the side groove 3.
[0033] In the specific implementation process, it is worth noting that the use of reinforcing rib 5 increases the strength of the gear, enabling it to cope with different loads and improving the overall strength of the gear.
[0034] Furthermore, the inner wall of the boss 4 is provided with a mounting groove 14. The inner wall of the mounting groove 14 is rotatably connected to a locking block 17 via a pin. The outer wall of the locking block 17 is inserted into the outer wall of the rotating shaft 6. One end of the locking block 17 extending into the mounting groove 14 is fixedly connected to a counterweight 15. The outer wall of the counterweight 15 presses against the spring 16. The outer wall of the spring 16 is fixedly connected to the inner wall of the mounting groove 14.
[0035] In the specific implementation process, it is worth noting that the counterweight 15 is fixed at a position away from the connection between the locking block 17 and the mounting groove 14. In this way, when the gear rotates, the counterweight 15, under the action of centrifugal force, makes the locking block 17 lock on the outer wall of the rotating shaft 6, preventing the rotating shaft 6 and the gear from moving back and forth. Moreover, an opening is provided on the outer wall of the rotating shaft 6 to satisfy the locking block 17 to lock on the outer wall of the rotating shaft 6. When the gear is not rotating, the counterweight 15 will move towards the opening of the mounting groove 14 under the action of the spring 16. When the counterweight 15 moves, the locking block 17 will rotate upward around the position where it is connected to the mounting groove 14, so that the locking block 17 and the rotating shaft 6 are separated. In this way, the removal of the rotating shaft 6 will not be affected by the locking block 17. On the contrary, when rotating, the locking block 17 will make the rotating shaft 6 and the gear stably connected.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
