Description

Technical Field

[0001] This utility model specifically relates to a toothed coupling that is easy to replace. Background Technology

[0002] A coupling is a device that connects two shafts or a shaft and a rotating component, allowing them to rotate together during motion and power transmission, and remaining connected under normal conditions. Sometimes it is also used as a safety device to prevent the connected components from bearing excessive loads, thus providing overload protection.

[0003] In the installation of traditional couplings, fine adjustments to the equipment are often required to achieve alignment. However, for couplings with interference fits, this operation is extremely challenging, often necessitating disassembly and reassembly to achieve precise alignment. Utility Model Content

[0004] Purpose of the utility model: To provide a toothed coupling that is easy to replace, thereby solving the above-mentioned problems existing in the prior art.

[0005] Technical solution: A replaceable gear coupling includes two sets of connecting shafts and a coupling assembly. The coupling assembly is installed between the connecting shafts and sleeved onto them. Each set of connecting shafts has a limiting part installed at its end near the coupling assembly. The limiting part is connected to the coupling assembly in a limiting manner. Each set of connecting shafts also has a limiting spline installed on its outer wall. Limiting keyways are formed at both ends of the coupling assembly. The limiting spline is inserted into the limiting keyways to form a connection limiting.

[0006] Preferably, the limiting part includes a plurality of limiting posts, which are circumferentially arrayed and mounted on the outer wall of the end of the connecting shaft near the coupling assembly.

[0007] Preferably, the coupling assembly includes two sets of bushings, the limiting keyway is formed on the inner wall of the bushing along the length direction of the bushing, the bushing is sleeved on the end of the connecting shaft, a connecting ring is installed at the end of the bushing away from the connecting shaft, a plurality of mounting grooves are formed on the inner wall of the connecting ring, a portion of the limiting part is placed in the mounting groove, and a plurality of mounting holes are formed on the edge of the connecting ring.

[0008] Preferably, both the bushing and the connecting ring are made of metal.

[0009] Preferably, the coupling assembly further includes a connecting column, which is installed at the end of the connecting ring. Mounting rings are installed at both ends of the connecting column. The inner wall of the mounting ring has several connecting grooves, which correspond one-to-one with the mounting grooves to form a receiving space for placing the limiting part. Several connecting holes are provided along the edge of the mounting ring, which correspond one-to-one with the mounting holes. The bushing and the connecting column are connected and fixed by mutual cooperation in the mounting holes, connecting holes, and connecting parts.

[0010] Preferably, both the connecting post and the mounting ring are made of metal.

[0011] Beneficial effects: This utility model relates to a replaceable gear coupling. By inserting the connecting shaft into the bushing in the coupling assembly, and using the interlocking of the limiting spline and limiting keyway, the connecting shaft and bushing can be precisely aligned. Then, through the cooperation of the connecting parts with the mounting holes and connecting holes, the bushing and connecting ring are connected and positioned. At this time, the two sets of connecting shafts are accurately aligned. Due to the interlocking of the limiting spline and limiting keyway, there will be no relative rotation or displacement between the connecting shaft and bushing, ensuring the accuracy and efficiency of power transmission.
