Self-locking coupler

Abstract

The invention discloses a self-locking coupler, which belongs to the technical field of couplers and comprises a coupling box; one side of the coupling box is fixedly connected with a coupling sleeve connected with an external driving mechanism; an inner cavity of the coupling box is provided with an energy absorption mechanism; one side of the energy absorption mechanism is movably connected with a transverse adjusting mechanism for transverse adjustment; one side of the transverse adjusting mechanism is connected with an assembling base through a universal mechanism capable of being adjusted in a multi-axis mode; and an inner cavity of the assembling base is movably connected with a fast-assembling type axial assembling mechanism. According to the invention, an inserted connecting shaft body and the assembling base on one side are fully attached, limited and fixed through the assembling sleeve and a tightening ring which are close to each other; therefore, self-locking assembling with the connecting shaft body can be achieved by screwing a fastening lead screw body; then the portability and stability of coupling assembly limiting can be remarkably improved; and the requirement of quick overhaul and maintenance can be met.

Description

technical field [0001] The invention belongs to the technical field of shaft couplings, in particular to a self-locking shaft coupling. Background technique [0002] Coupling refers to a device that connects two shafts or shafts and rotating parts, and rotates together during the transmission of motion and power, and does not disengage under normal conditions. Sometimes it is also used as a safety device to prevent the connected parts from being subjected to excessive loads and play the role of overload protection. The coupling is also called a coupling. A mechanical component used to firmly couple the driving shaft and the driven shaft in different mechanisms to rotate together and transmit motion and torque. Sometimes it is also used to connect shafts and other parts (such as gears, pulleys, etc.), often composed of two halves, respectively connected by keys or tight fits, fastened to the ends of the two shafts, and then connected in some way to the two halves . The cou...
