Technical Field
The utility model relates to the technical field of couplings, in particular to a self-locking elastic coupling.
Background
In the existing elastic couplings, most of the shaft bodies are connected with the couplings by old flat keys. When the shaft body is connected with the coupler, if the size of the inner hole and the length of the coupler are in error, the shaft body and the inner hole are difficult to assemble; when the length of the coupler is in error, the coupler can generate the phenomena of axial movement and the like during normal use after the installation is completed.
Meanwhile, the flat key is adopted for connection, when the flat key is used for a long time, abrasion of the flat key, the shaft body and the key groove of the inner hole of the coupler can occur, so that transmission precision is reduced, when the transmission precision is serious, the shaft body and the coupler can be seriously damaged, equipment cannot be normally used, and only parts such as the shaft body and the coupler can be replaced. The waste of production time is caused, and the corresponding maintenance cost is increased.
Therefore, we propose a self-locking elastic coupling in order to solve the above-mentioned problems.
