Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to a high-strength and corrosion-resistant diaphragm coupling for special vehicles. Background Art

[0002] With the increasing demand for special vehicles in various extreme environments, traditional couplings are often unable to withstand highly corrosive environments and high-load working environments, resulting in couplings that are easily damaged, have short service lives, and require frequent maintenance. Therefore, it is urgent to develop a coupling that can withstand both highly corrosive environments and high torque loads.

[0003] A Chinese patent discloses a diaphragm coupling (publication number: CN 216009300 U) comprising: a first coupling for connecting an input shaft; a second coupling for connecting an output shaft; an intermediate section provided between the first coupling and the second coupling, the intermediate section being connected to the first coupling and the second coupling via an elastic diaphragm; an anti-compression member connecting the first coupling and the second coupling so that the first coupling and the second coupling are relatively fixed in the axial direction. However, the diaphragm coupling has a complex structure and is often difficult to withstand highly corrosive environments and high-load working environments, resulting in the coupling being easily damaged, having a short service life, and requiring frequent maintenance. Therefore, a high-strength and corrosion-resistant diaphragm coupling for special vehicles is required. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the existing diaphragm coupling in the prior art, such as the complex structure of the existing diaphragm coupling, which is often difficult to withstand highly corrosive environments and high-load working environments, resulting in the coupling being easily damaged, having a short service life and requiring frequent maintenance, and to propose a high-strength and corrosion-resistant diaphragm coupling for special vehicles.

[0005] The technical solution adopted by the utility model to solve its technical problems is: the utility model describes a high-strength and corrosion-resistant diaphragm coupling for special vehicles, including a coupling body, characterized in that: the coupling body includes an inner ring and an outer pressure ring, a diaphragm piece is provided on one side of the inner ring and the outer pressure ring, the number of the diaphragm pieces is 7 and the thickness of each piece is 1 mm, the diaphragm piece is composed of a first diaphragm group and a second diaphragm group, the other side of the diaphragm piece is provided with an inner ring and an inner pressure ring, and outer pressure plates are provided at both ends of the diaphragm piece.

[0006] Preferably, the first diaphragm group includes the 1st, 3rd, 5th and 7th diaphragms, and the yield strength of the 1st, 3rd, 5th and 7th diaphragms is ≥784MPa. The second diaphragm group includes the 2nd, 4th and 6th diaphragms. The diaphragm members of the first diaphragm group and the second diaphragm group are alternately arranged and matched without gaps. This arrangement optimizes the force transmission path, improves the torque transmission efficiency, reduces the wear between the diaphragm members, and extends the service life of the coupling.

[0007] Preferably, cross slot countersunk screws are provided between the inner ring outer pressure ring, the diaphragm group and the inner ring inner pressure ring, and the number of the cross slot countersunk screws is 4. This design provides reliable mechanical fixation, ensuring that the diaphragm can remain stable under high load conditions and reducing failures caused by loose coupling components.

[0008] Preferably, the inner ring outer pressure ring and the inner ring inner pressure ring are both made of spring steel, and the yield strength of the inner ring outer pressure ring and the inner ring inner pressure ring is ≥784MPa. The use of high-strength materials ensures that the coupling maintains structural integrity and functional reliability under extreme working conditions, meeting the high standards for couplings for special vehicles.

[0009] Preferably, the outer wall of the outer pressure plate is provided with mounting holes on its circumference, the aperture of the mounting holes is φ13±0.2, and the number of holes in each group is 2, which are evenly distributed in 8 groups. This design enables the outer pressure plate to be firmly installed in the power transmission system of the special vehicle, ensuring the stability and center positioning of the coupling during operation.

[0010] The utility model is beneficial in that:

[0011] By using high-strength corrosion-resistant materials (such as spring steel) and combining the structural design of the diaphragm parts, the coupling can maintain long-term corrosion resistance under harsh environmental conditions (such as high salt spray, high humidity and other environments that special vehicles may encounter), and prolongs its service life. The gapless alternating arrangement and precise matching between the diaphragm parts, as well as the optimized diaphragm group structure, make the torque transmission smoother and more efficient, reduce power loss, and improve transmission efficiency. Four cross-slot countersunk screws are used to fix the inner ring outer pressure ring, the diaphragm group and the inner ring inner pressure ring, which increases the overall rigidity and stability of the coupling and ensures that no relative displacement occurs between the components under high-load working conditions; the design of the outer pressure plate has a mounting hole of a specific size, which is convenient for the installation and positioning of the coupling, and also facilitates daily maintenance and inspection, reducing maintenance costs; the diaphragm parts of the first diaphragm group have a high yield strength of ≥784MPa, which provides the coupling with extremely high load-bearing capacity and overload resistance, and is suitable for the use requirements of special vehicles under extreme working conditions.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0018] See also Figure 1-2 As shown, a high-strength and corrosion-resistant diaphragm coupling for special vehicles includes a coupling body, characterized in that: the coupling body includes an inner ring outer pressure ring 4, a diaphragm piece is provided on one side of the inner ring outer pressure ring 4, the number of the diaphragm pieces is 7 and the thickness of each piece is 1 mm, the diaphragm piece is composed of a first diaphragm group 1 and a second diaphragm group 2, an inner ring inner pressure ring 5 is provided on the other side of the diaphragm piece, and outer pressure plates 3 are provided at both ends of the diaphragm piece.

[0019] In this embodiment, the first diaphragm group 1 includes the 1st, 3rd, 5th and 7th diaphragms, and the yield strength of the 1st, 3rd, 5th and 7th diaphragms is ≥784MPa. The second diaphragm group 2 includes the 2nd, 4th and 6th diaphragms. The diaphragms of the first diaphragm group 1 and the second diaphragm group 2 are alternately arranged and matched without gaps. This arrangement optimizes the force transmission path, improves the torque transmission efficiency, and reduces the wear between the diaphragm parts, thereby extending the service life of the coupling.

[0020] In this embodiment, cross recessed countersunk screws 6 are provided between the inner ring outer pressure ring 4, the diaphragm group and the inner ring inner pressure ring 5. The number of the cross recessed countersunk screws 6 is 4. This design provides reliable mechanical fixation, ensuring that the diaphragm can remain stable under high load conditions and reducing failures caused by loose coupling components.

[0021] In this embodiment, the inner ring outer pressure ring 4 and the inner ring inner pressure ring 5 are both made of spring steel. The spring steel is a common product on the market and can be purchased directly. The yield strength of the inner ring outer pressure ring 4 and the inner ring inner pressure ring 5 is ≥784MPa. The use of high-strength materials ensures that the coupling maintains structural integrity and functional reliability under extreme working conditions, meeting the high standards for couplings of special vehicles.

[0022] In this embodiment, the outer wall circumference of the outer pressure plate 3 is provided with mounting holes 7, the aperture of the mounting holes 7 is φ13±0.2, the number of holes in each group is 2, and the number of holes 7 is evenly distributed in 8 groups. This design enables the outer pressure plate 3 to be firmly installed in the power transmission system of the special vehicle, ensuring the stability and center positioning of the coupling during operation.

[0023] The implementation principle of this embodiment is: when the matching driving end (such as an engine) generates rotational power, the inner ring outer pressure ring 4 receives the torque and transmits it to the diaphragm member. Due to its specific alternating arrangement and gap-free fit, the diaphragm member can effectively transmit the torque to the inner ring inner pressure ring 5, and finally transmit the power to the matching driven end (such as a drive shaft). The outer pressure plate 3 provides additional support and protection for the diaphragm member, and the cross-slot countersunk screw 6 fixes the inner ring outer pressure ring 4, the diaphragm group and the inner ring inner pressure ring 5 in series to ensure that all components become an integrated stable structure.
