[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with illustrations and specific embodiments.

[0024] like Figure 1 to Figure 2 As shown, a drum-shaped gear coupling proposed by the utility model comprises an external gear sleeve 1, on which is opened an axial hole for accommodating a transmission shaft; an internal gear ring 2, which is arranged on the external gear sleeve 1, and the inner ring of the internal gear ring 2 matches with the outer wall of the external gear sleeve 1; a stopper 3, which is arranged at the end of the internal gear sleeve 2, and the stopper 3 and the internal gear sleeve 2 are detachably connected, and the stopper 3 is used to limit the axial movement of the internal gear ring 2; a connecting flange 4, which is located at the end of the external gear sleeve 1, and the first end of the connecting flange 4 is detachably mounted on the external gear sleeve 1, and the second end of the connecting flange 4 is detachably connected to the external sleeve.

[0025] The utility model simplifies the installation process through the detachable design. Through simple disassembly and assembly steps, the staff can quickly complete the installation of the coupling, improving work efficiency. At the same time, this design also facilitates the replacement and maintenance of components. When a component fails or needs to be upgraded, it can be easily disassembled and replaced without large-scale disassembly or replacement of the entire coupling.

[0026] Secondly, the detachable design enhances the adaptability of the coupling. Since different working environments and transmission requirements may require the use of different components or configurations, the detachable design enables the coupling to easily adapt to these changes. By replacing different components or adjusting the connection method, the coupling can meet different transmission requirements, improving its flexibility and wide application.

[0027] In this embodiment, a plurality of connection holes 1 are formed on the connection flange 4, a plurality of connection holes 2 matching the connection holes 1 are formed on the external gear sleeve 1, and a fixing screw 1 5 passes through the connection hole 1 and extends into the connection hole 2 to fix the connection flange 4 to the end of the external gear sleeve 1, and the connection flange 4 is tightly fixed to the end of the external gear sleeve 1. This fixing method is not only firm and reliable, but also has certain vibration and impact resistance capabilities.

[0028] In this embodiment, a plurality of positioning holes 1 are provided on the connecting flange 4, and a plurality of positioning holes 2 matching the positioning holes 1 are provided on the external sleeve. The positioning holes 1 and 2 cooperate with the positioning pin 6 to realize the positioning between the connecting flange 4 and the external sleeve. When the flange is installed, the positioning pin 6 can be replaced with a fixing screw to improve the connection stability between the connecting flange 4 and the external sleeve.

[0029] In this embodiment, a plurality of connection holes three are provided on the connection flange 4, a plurality of connection holes four matching the connection holes three are provided on the external sleeve, a fixing bolt 7 passes through the connection hole three and extends into the connection hole four to fix the external sleeve on the connection flange 4, and the end of the fixing bolt 7 is locked by a fixing nut. When the external sleeve needs to be replaced, only the fixing bolt 7 needs to be unscrewed.

[0030] In this embodiment, a connection hole 5 is provided on the stopper 3, and a connection hole 6 matching the connection hole 5 is provided on the inner gear ring 2. The fixing screw 2 8 passes through the connection hole 5 and extends into the connection hole 6 to fix the stopper 3 on the inner gear ring 2. The stopper 3 is tightly fixed on the inner gear ring 2. The stopper 3 can effectively limit and archive the inner gear ring 2 to prevent it from shifting or falling off during the working process. When the stopper 3 needs to be removed for maintenance or replacement, the operation is also simple. The stopper 3 can be easily removed from the inner gear ring 2 by simply unscrewing the fixing screw 2 8. This makes maintenance more convenient and efficient.

[0031] In this embodiment, an oil filling hole 9 is provided on the inner gear ring 2, which is used to inject lubricating oil into the tooth surface gap between the inner gear ring 2 and the outer gear sleeve 1 to ensure good lubrication of the tooth surface and reduce wear. The oil filling hole 9 observes the inner gear ring 2, and a sealing plug 10 is arranged in the oil filling hole 9; the sealing plug 10 is usually made of elastic material and can fit tightly at the opening of the oil filling hole 9 to form an effective seal.

[0032] The use process and principle of the utility model are as follows: During the installation process, first, the inner gear ring 2 is sleeved on the outer gear sleeve 1 to ensure that the inner ring of the inner gear ring 2 matches the outer wall of the outer gear sleeve 1. Then, the stopper 3 is fixed to the end of the inner gear ring 2 by the fixing screw 8 to limit the axial movement of the inner gear ring 2. Next, the connecting flange 4 is fixed to the end of the outer gear sleeve 1 by the fixing screw 5. Finally, the external sleeve is connected to the connecting flange 4 by the positioning pin 6 and the fixing bolt 7. During use, the lubricating oil is injected into the tooth surface gap through the oil filling hole 9 on the inner gear ring 2 to ensure good lubrication of the tooth surface. The detachable connection between the components ensures the stability and reliability of the transmission. When maintenance or replacement of components is required, it is only necessary to disassemble according to the reverse steps. For example, when the external sleeve needs to be replaced, it is only necessary to unscrew the fixing bolt 7 and remove the external sleeve from the connecting flange 4; when the stopper 3 needs to be replaced, it is only necessary to unscrew the fixing screw 8 and remove the stopper 3 from the inner gear ring 2. This detachable design makes maintenance operations simple and convenient.
