Abstract
The invention relates to an eight-joint shaft coupler. According to the technical scheme, the eight-joint shaft coupler is formed by four twisting connecting rods, four rotating connecting rods, two connecting discs and two connecting flanges. Perpendicular end holes are formed in the two ends of each twisting connecting rod respectively. Symmetrically-arranged couplings are arranged on each connecting disc. The connecting discs are connected with the connecting flanges. Between the two connecting discs, the four twisting connecting rods are sequentially connected together through the four rotating connecting rods to form a complete spatial three-dimensional closed structure. Pin shafts penetrate through holes in the middles of the rotating connecting rods to integrally connect the rotating connecting rods with the couplings. Keys are arranged on the connecting flanges. The novel eight-joint shaft coupler capable of achieving large angle compensation and large displacement compensation is provided through analysis of the principle of a conventional flexible shaft coupler and observing of actual working conditions. By means of the eight-joint shaft coupler, the service life can be prolonged, the use safety can be improved, and disassembling and assembling are quite convenient.
