Universal coupling ground shaft for strand rope machine

Abstract

The invention discloses a universal coupling ground shaft for a strand rope machine. The universal coupling ground shaft is formed by an integral structure which is welded by single-universal-joint universal couplings at two ends and middle shafts to replace a solid structure ground shaft; a connecting bearing base and the universal couplings are connected through flanges and connecting bolts; the connecting bearing base plays a role in bearing sections of the ground shaft in the middle section of a machine body; the number of the ground shafts of the machine body part is identical to that of cylinders and the length is equal to that of the cylinder length; the ground shafts which are close to toothed belt transmission, between the machine body ground shaft tail end connecting bearing base and a lay length box and between the lay length box and a traction box are formed by welding of two single-universal-joint couplings and an extensible middle shaft and the rest ground shafts are formed by welding two single-universal-joint couplings and a non-extensible middle shaft. The universal coupling ground shaft is small in rotational inertia, large in flexure strength and not easy to deform. The universal coupling is strong in center adjusting capability, low in installation accuracy requirement, saves costs and is high in operation efficiency.

Description

Technical field [0001] The invention relates to a universal joint shaft used for a wire rope machine, belonging to the technical field of metal product processing equipment. Background technique [0002] The ground shaft of the strand machine usually uses a solid shaft, the connection between the shafts uses a shell coupling, and the support of the ground shaft adopts UCP seated bearings. This structure has high requirements on the processing accuracy and installation accuracy of the ground shaft itself, and it is easy to cause support bearings. And damage to the joints. The invention is based on the offset ground shaft (a pair of toothed belts are used to transmit the movement of the main transmission box to the ground shaft from below the center of the cylinder to the back of the main machine base, and the ground shaft of the rope machine is set behind the main machine base) On the above, the connection of the earth shaft, the support and structure of the earth shaft h...
