Abstract

The invention provides a safety coupler. The safety coupler comprises a first half coupler, a core shaft, a second half coupler assembly and a third half coupler. The first half coupler comprises a first drum-shaped tooth coupling part which is in meshing connection with a tooth groove and a first transition part. One end of the core shaft is connected with the first transition part through a bolt, the connecting face is provided with a meshed tooth groove structure, the connection manner is tight, the torque capable of being borne is greatly increased, and the bolt at the connecting positionis not prone to loosening or fracture. The core shaft is sleeved with the second half coupler assembly, and the core shaft and the second half coupler assembly are connected through a safety pin shaft. The second half coupler assembly comprises two pairs of drum-shaped tooth meshing parts, so that the whole safety coupler has more axis deviation compensation amounts in the radial direction, the axial direction, the angular direction and the like, the situation of safety pin breakage under the rated load is avoided, and the capacity of the machine is released to the maximum degree. The whole safety coupler is simple and reasonable in structure, maintenance and usage are convenient, the service life is long, and important significance is achieved for safety coupler development.

Description

technical field [0001] The invention belongs to the technical field of shaft couplings, and in particular relates to a safety coupling. Background technique [0002] The safety coupling is a component that connects the main machine and the working machine. Its main function is overload protection. During on-site installation, the corresponding alignment requirements for the output shaft of the main machine and the input shaft of the working machine are very high. If the alignment accuracy cannot be achieved, the safety pin will break under the rated load, which greatly restricts the release of the machine's production capacity. [0003] Therefore, it is necessary to provide a safety coupling that addresses the above-mentioned deficiencies in the prior art. Contents of the invention [0004] The purpose of the present invention is to provide a safety coupling to at least solve the current problems of high alignment accuracy of the safety coupling and limited machine capaci...
