Abstract
The invention provides an improved elastic pin coupling and an assembling method thereof. The improved elastic pin coupling comprises a semi-coupling main body, a flange hole, a pin, a penetrating screw hole, a long bolt and an assorted nut. The flange hole and the penetrating screw hole are formed in the semi-coupling main body. The improved elastic pin coupling has the advantages that when the improved elastic pin coupling is assembled, components of the whole coupling are connected to one another integrally and stably; two shafts are strictly and accurately centered; the displacement and the offset angle of the coupling main body in various directions are limited to a certain degree, so that the assembling precision and the assembling quality are guaranteed; the rework possibility is reduced; and the assembling efficiency is improved. The improved elastic pin coupling is packaged, conveyed or transferred conveniently and safely, and is simple and reasonable in structure, low in cost and convenient to repair.
