Description

Technical Field

[0001] This utility model belongs to the field of mechanical transmission technology, and in particular relates to a coupling that is easy to assemble and disassemble. Background Technology

[0002] Couplings are common components used in mechanical transmissions to connect two shafts (driving shaft and driven shaft) so that they rotate together to transmit torque. Among them, the shim, as an elastic connecting element, is often placed between two half-couplings (or connecting plates) to compensate for the relative displacement of the two shafts, buffer and absorb vibration by utilizing the elastic deformation of the shim.

[0003] In existing technologies, when installing or replacing galvanic shims, operators need to align and close the two half-couplings. However, the alignment process (ensuring the coaxiality of the two half-couplings) is often cumbersome. Operators often need to use measuring tools such as dial indicators for repeated adjustments, or rely entirely on experience for visual inspection. This not only leads to low installation efficiency but also makes it difficult to guarantee alignment accuracy. Poor alignment can directly cause severe vibrations during equipment operation, accelerating the wear of the galvanic shims and bearings.

[0004] In addition, after initial alignment, operators need to manually hold the two half-couplings and the central shim in the correct position while simultaneously inserting and tightening the fixing screws. This operation is very inconvenient in on-site maintenance or confined spaces, often requiring multiple people or auxiliary tools. This makes the entire coupling assembly and disassembly process (i.e., "reassembly and disassembly") time-consuming, labor-intensive, and inconvenient.

[0005] Therefore, this utility model proposes a coupling that is easy to assemble and disassemble in order to overcome the shortcomings of the prior art. Utility Model Content

[0006] The purpose of this utility model is to provide a coupling that is easy to assemble and disassemble, in order to solve the problems of difficult alignment and cumbersome installation process caused by the lack of effective positioning and pre-tightening structure in the existing couplings.

The arc-shaped locking pin is connected to a lever. The easy-installation assembly also includes a hook lock rotatably connected to the housing, which is used to engage the slot.

[0010] Preferably, the positioning and mounting assembly further includes a top screw and a screw hole, the screw hole being formed in the lower connecting plate and communicating with the U-shaped groove, the top screw being screwed into the screw hole and abutting against the double-sided pin.

[0011] Preferably, the easy-installation component further includes a rotating sleeve that is fitted onto the hook lock and rotates synchronously with it.
