[0002] In the fields of mechanical transmission and marine drive systems, drum gear couplings, as important components connecting two shafts and transmitting torque, are widely used in various industrial equipment and marine drive systems. However, traditional drum gear couplings have certain limitations in practical use: First, they lack sufficient positioning and clamping accuracy for round or square instrument components, especially under conditions of lateral offset or tilt angle, which can easily lead to a decrease in transmission stability. Second, the sealing structure design has defects; in environments with high humidity, dust, or corrosive media, external impurities can easily enter the coupling, causing wear or corrosion on the tooth surface and affecting its service life. Therefore, it is necessary to provide a new drum gear coupling to solve the above technical problems. Utility Model Content

[0009] As a further embodiment of this utility model, a baffle is provided between the first internal tooth and the second internal tooth, and an anti-collision pin is installed on the baffle. The anti-collision pin is adapted to the first end cover and the second end cover.

[0010] As a further embodiment of this utility model, the inner gear one, the inner gear two, and the baffle are connected and fixed by a connecting structure.

[0012] Compared with related technologies, the drum-shaped gear coupling provided by this utility model has the following beneficial effects:

[0013] 1. This utility model, through the design of left and right tooth structures, can effectively position and clamp the parts of round or square instruments and meters. It can process the sides and tilt angles to adapt to the connection requirements of parts under different installation conditions, ensure the positional accuracy of parts during transmission, and improve the stability of equipment operation.

[0014] 2. This utility model forms a reliable seal on the internal teeth and spacer through the matching structure of the sealing ring and the gland, effectively preventing external impurities from entering the coupling, reducing tooth surface wear and corrosion, and extending the service life of the coupling. It is especially suitable for harsh environments with high humidity, high dust or corrosive media.

[0015] 3. Based on the meshing design of the external gear ring and the internal gear, this utility model enables the coupling to have radial, axial and angular axis deviation compensation capabilities, which can adapt to various offsets that may occur between the two shafts during operation, reduce the generation of additional loads, improve transmission efficiency, reduce noise, and ensure the stable operation of the equipment.

[0016] 4. The baffles and anti-collision pins effectively limit the displacement of components when the equipment is subjected to impact or vibration, providing axial positioning and impact resistance, enhancing the structural strength and stability of the coupling, reducing component loosening caused by vibration, and improving the reliability of the equipment under complex working conditions. Furthermore, the components are connected and fixed by standard parts such as bolts and nuts, resulting in a compact structure, small turning radius, and easy installation and disassembly. At the same time, the use of mature connection technology and standard parts reduces manufacturing and maintenance costs and improves production efficiency. Attached Figure Description

[0024] The inner tooth 1 has a cover groove 1, and the end cap 1 is disposed in the cover groove 1. The end cap 1 and the inner tooth 1 are connected and fixed by a screw 1.

[0025] The right tooth structure includes a spacer 10, a screw 11, an end cap 12, an inner tooth 14, and a sealing ring 2. The inner tooth 14 is located on the right side of the inner tooth 1, and a cover groove 2 is provided on the inner tooth 14. The end cap 12 is located in the cover groove 2, and the end cap 12 and the inner tooth 14 are connected and fixed by the screw 11.

[0026] The spacer 10 is fitted onto the inner tooth 14. The inner wall of the inner hole of the spacer 10 is provided with a sealing groove 2. The sealing ring 2 is installed in the sealing groove 2 and is adapted to the inner tooth 14.

[0027] A baffle 7 is provided between the inner tooth 1 and the inner tooth 2 14, and an anti-collision pin 13 is installed on the baffle 7. The anti-collision pin 13 is adapted to the end cap 1 and the end cap 2 12.

[0028] The inner gear 1, inner gear 2 14, and baffle 7 are connected and fixed by a connecting structure. The connecting structure includes multiple pressure cap bolts 4, outer gear ring 5, multiple connecting bolts 6, multiple nuts 8, and outer gear ring 2 9.

The outer gear ring 5 and outer gear ring 2 9 clamp the connecting baffle 7. The outer gear ring 5 and outer gear ring 2 9 are connected and fixed by connecting bolts 6 and nuts 8.

[0030] For humidity levels of 90%–96%, 2 mg / m³ 3 In salt spray environments, before coating equipment, the surface to be coated must be treated to achieve Sa2.5 and a roughness of 40-80um, and coating products suitable for marine atmospheric environments should be used.

[0031] For vertical installations in vibrating environments that require stability, a baffle and anti-collision pins are installed, which are tightly fitted together. The anti-collision pins are designed with ball heads at both ends, which can provide axial positioning while allowing for a certain degree of deviation during operation, and have the ability to compensate for radial, axial and angular axis deviations.

[0032] The working principle of the drum-shaped gear coupling provided by this utility model is as follows:

[0033] First step: Internal gear 1 and internal gear 2 14 are connected to the two end shafts respectively. External gear ring 5 is sleeved on internal gear 1 and external gear ring 2 9 is sleeved on internal gear 2 14. The meshing structure of the external gear ring and the internal gear allows the two shafts to have certain deviations in the radial, axial and angular directions, thereby realizing shaft deviation compensation. When the two shafts are relatively offset, the external gear ring can swing within a certain range, transmit torque through the meshing of the tooth surfaces, and adapt to the relative displacement of the shafts at the same time.

[0034] The second step: The sealing ring 12 is fitted onto the inner tooth 1, and the sealing groove 1 on its inner wall is fitted with the pressure cap 3. The pressure cap 3 is connected and fixed to the inner tooth 1 by the pressure cap bolt 4 to form a sealing structure to prevent external dust, liquid and other impurities from entering the interior of the left tooth structure. Similarly, the spacer 10 is fitted onto the inner tooth 14, and the sealing ring 2 is installed in the sealing groove 2 to achieve the sealing of the right tooth structure and effectively protect the internal tooth surface and connecting parts.

[0035] Third step: A baffle 7 is set between the inner gear 1 and the inner gear 2 14. The anti-collision pin 13 installed on the baffle 7 is adapted to the end cover 1 and the end cover 2 12. When the equipment starts, stops or is impacted, the anti-collision pin 13 can limit the displacement of the end cover, play an axial positioning and anti-impact role, and prevent the parts from being damaged by collision.

[0036] Fourth step: External gear ring 1 5 and external gear ring 2 9 are clamped to the connecting baffle 7 by connecting bolts 6 and nuts 8, fixing the left gear structure, right gear structure and baffle 7 into a whole, ensuring that the components work together, the force is evenly distributed when transmitting torque, and improving the overall stability and reliability of the coupling.
