Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to a combined coupling. Background Art

[0002] A coupling is a device that connects two shafts or a shaft and a rotating part, and rotates together during the transmission of motion and power, and does not disengage under normal circumstances. Sometimes it is also used as a safety device to prevent the connected parts from being subjected to excessive loads, playing the role of overload protection. The length of the coupling is generally fixed. When the distance between the two shafts is greater than the length of the coupling, the coupling cannot connect the two shafts. Therefore, a combined coupling is proposed to facilitate adjustment and connection of the two shafts. Utility Model Content

The spacing between the two connecting sleeves can be adjusted according to the distance between the two shafts, so that one shaft is inserted into one connecting sleeve, and the other shaft is inserted into the other connecting sleeve. The four locking bolts are tightened, and the clamping block and the connecting sleeve can clamp the shaft. The nut on the threaded column is tightened, and when one shaft rotates, the connecting sleeve, the coupling body, and the other connecting sleeve are driven to rotate, and the other shaft rotates accordingly, which solves the problem that the coupling cannot connect the two shafts when the distance between the two shafts is greater than the length of the coupling.

[0006] Specifically, the outer wall of each connecting sleeve is integrally formed with two blocks, each block is provided with a through hole, each through hole is provided with a guide rod, and the ends of each guide rod away from the clamping block are connected to the coupling body.

By loosening the nut on the threaded column and pulling out the two connecting sleeves, the spacing between the two connecting sleeves can be adjusted according to the distance between the two shafts, so that one shaft is inserted into one of the connecting sleeves and the other shaft is inserted into the other connecting sleeve. By tightening the four locking bolts, the clamping block and the connecting sleeve can clamp the shafts. By tightening the nut on the threaded column, when one shaft rotates, it drives the connecting sleeve, the coupling body and the other connecting sleeve to rotate, and the other shaft rotates accordingly, thus solving the problem that the coupling cannot connect the two shafts when the distance between the two shafts is greater than the length of the coupling.

[0016] (2) In the combined coupling described in the utility model, the guide rod cooperates with the through hole in the stopper, which is not only conducive to the positioning of the connecting sleeve, but also can improve the stability of the connecting sleeve.
