Description

Technical Field

[0001] This utility model specifically relates to a dynamically adjustable coupling. Background Technology

[0002] A coupling is a device used to connect two shafts or a shaft to a rotating component. It keeps both shafts rotating synchronously during the transmission of motion and power, and they do not separate under normal operating conditions. Furthermore, couplings are sometimes designed as a safety mechanism to protect connected mechanical components from excessive loads, providing overload protection.

[0003] However, existing couplings typically have a fixed length. When the distance between the two shafts to be connected exceeds the original length of the coupling, it is impossible to directly use such a standard-sized coupling to complete the connection between the two shafts. To overcome this limitation, this application proposes a coupling with an adjusting cavity. In this way, the effective length of the coupling can be flexibly adjusted to adapt to the needs of shaft connections with different spacing. Utility Model Content

[0004] Purpose of the utility model: To provide a dynamically adjustable coupling that solves the above-mentioned problems existing in the prior art.

[0005] Technical solution: A dynamically adjustable coupling includes two sets of rotating shafts, with a coupling assembly installed between the two sets of rotating shafts. The coupling assembly includes at least two sets of coupling sleeves, each set of coupling sleeves respectively sleeves onto the rotating shafts, and the coupling sleeves are sleeved onto each other. A transmission assembly is installed between the coupling sleeves, and the transmission assembly is used to drive the two sets of coupling sleeves to move relative to each other to adapt to the distance between the two sets of rotating shafts. A limit component is installed on the outer wall of the coupling sleeve, and the limit component is used to limit the overall length of the coupling assembly.

[0006] Preferably, the limiting component includes a limiting member, which is installed on the outer wall end of one of the coupling sleeves, and the outer wall of the other coupling sleeve has a plurality of limiting grooves arranged in a linear array. A portion of the limiting member is inserted into the limiting groove to form a mutual connection and limiting between the two sets of coupling sleeves.

[0007] Preferably, the limiting member includes a mounting base, which is mounted on the end of the coupling sleeve. A limiting rod is rotatably mounted on the top of the mounting base via a mounting shaft. The end of the limiting rod is used to insert into a limiting groove. A torsion spring is installed between the mounting base and the limiting rod. The torsion spring is sleeved on the mounting shaft. One end of the torsion spring abuts against the limiting rod, and the other end of the torsion spring abuts against the coupling sleeve.

[0008] Preferably, the limiting component includes two sets of coupling sleeves with a plurality of threaded holes linearly arrayed on their outer walls, the threaded holes on the two sets of coupling sleeves corresponding one to one, and a connecting member threaded into the threaded hole, the connecting member being used to limit the mutual connection of the two sets of coupling sleeves.

[0009] Preferably, the transmission assembly includes a transmission gear, which is rotatably mounted on the outer wall of one of the coupling sleeves, and a spur rack is provided on the inner or outer wall of the other coupling sleeve, and the transmission gear meshes with the spur rack.

[0010] Preferably, each set of coupling sleeves has a connecting hole at its end and a keyway at its end. The keyway communicates with the connecting hole. The end of the rotating shaft is inserted into the connecting hole. A connecting key is installed on the outer wall of the end of the rotating shaft. The connecting key and the keyway cooperate with each other to form a connection limit.

[0011] Beneficial effects: This utility model relates to a dynamic adjustment coupling, which connects two rotating shafts by fitting a coupling sleeve onto the rotating shaft. During the connection process, the overlapping position of the coupling sleeves is adjusted by a transmission component to adjust the overall length of the coupling assembly, adapting to the connection between rotating shafts with different spacings. After the overall length of the coupling assembly is adjusted, the predetermined length of the coupling assembly is limited and fixed by the limiting component. Attached Figure Description

[0014] Example 1 like Figures 1 to 3 As shown, this utility model provides a technical solution: a dynamic adjusting coupling, including two sets of rotating shafts, with a coupling assembly installed between the two sets of rotating shafts. The coupling assembly includes at least two sets of coupling sleeves 1, each set of coupling sleeves 1 having a connecting hole 4 at its end, and a keyway 5 at its end, the keyway 5 communicating with the connecting hole 4. The end of the rotating shaft is inserted into the connecting hole 4, and a connecting key is installed on the outer wall of the end of the rotating shaft. The connecting key and the keyway 5 cooperate to form a connection limit. In this embodiment, three sets of coupling sleeves 1 are used, with two sets of coupling sleeves 1 respectively sleeved on the rotating shaft, and the coupling sleeves 1 sequentially sleeved on each other, as shown. Figure 3 As shown, a transmission assembly 2 is installed between the coupling sleeves 1. The transmission assembly 2 is used to drive the two sets of coupling sleeves 1 to move relative to each other, adapting to the distance between the two sets of rotating shafts. A limiting assembly 3 is installed on the outer wall of the coupling sleeve 1. The limiting assembly 3 is used to limit the overall length of the coupling assembly. The connection between the two rotating shafts is achieved by fitting the coupling sleeve 1 onto the rotating shaft. During the connection process, the positional relationship of the overlapping coupling sleeves 1 is adjusted by the transmission assembly 2 to adjust the overall length of the coupling assembly, adapting to the connection between rotating shafts with different distances. After the overall length of the coupling assembly is adjusted, the limiting component is used to limit and fix the predetermined length of the coupling assembly.

[0015] In a further embodiment, the transmission assembly 2 includes a transmission gear 21, which is rotatably mounted on the intermediate coupling sleeve 1. The outer and inner walls of the two sets of coupling sleeves 1, one inside and one outside, are respectively provided with racks 22. The transmission gear 21 meshes with the racks 22, and the overall length of the coupling assembly is adjusted by the mutual cooperation between the transmission gear 21 and the racks 22.

[0016] In a further embodiment, the limiting component 3 includes a limiting member, which is installed on the outer wall end of one of the coupling sleeves 1. The outer wall of the other coupling sleeve 1 is linearly arrayed with a plurality of limiting grooves 31. A portion of the limiting member is inserted into the limiting groove 31 to form a mutual connection and limiting for the two sets of coupling sleeves 1. The limiting member includes a mounting base 32, which is installed on the end of the coupling sleeve 1. A limiting rod 33 is rotatably mounted on the top of the mounting base 32 via a mounting shaft. The end of the limiting rod 33 is used to insert into the limiting groove 31. A torsion spring is installed between the mounting base 32 and the limiting rod 33. The torsion spring is sleeved on the mounting shaft. One end of the torsion spring abuts against the limiting rod 33, and the other end of the torsion spring abuts against the coupling sleeve 1.

[0017] Example 2 In this embodiment, as Figures 4 to 6As shown, the structure of the limiting component 3 is different from that of the limiting component 3 in Embodiment 1, but the other structures are the same. In this embodiment, the limiting component 3 includes two sets of coupling sleeves 1 with a plurality of threaded holes 34 linearly arrayed on their outer walls. The threaded holes 34 on the two sets of coupling sleeves 1 correspond one-to-one. The threaded holes 34 are internally threaded with connecting parts. The two sets of coupling sleeves 1 are connected and limited to each other by the connecting parts. In this embodiment, the connecting parts are bolts, but are not limited to bolts.
