Abstract

The invention relates to a pre-tightening, anti-loosening and balancing device for a spiral rotating shaft. The device comprises the spiral rotating shaft, a worm gear, a worm, a first rotating shaftseat body and a second rotating shaft seat body, wherein a spiral groove is formed in the middle of the spiral rotating shaft, a steel wire is wound on the spiral groove, an innermost end of the steelwire penetrates into the spiral rotating shaft and is fixed on a steel ball, a cylindrical shaft is arranged at one end of the spiral rotating shaft, a platform is arranged on the other end, a worm wheel with a platform inner hole is arranged on the platform shaft in a sleeving mode, the worm is arranged on the outer side of the worm gear and assembled in a worm mounting hole in the second rotating shaft seat body, an annular groove is formed at a tail end of the worm, a screw mounting hole is formed in the position, right opposite to the annular groove, of the second rotating shaft seat body, and a set screw is assembled in the screw mounting hole. The device has the advantages that pre-tightening design is added in a transmission mechanism of a steel wire rope through the spiral rotating shaft, so the steel wire rope is pre-tightened, the locking design of the tail end position of the worm is added, and a phenomenon that the steel wire rope is loosened due to self-rotation of the spiral rotating shaft caused by worm and gear matching loosening is prevented.

Description

technical field [0001] The invention relates to the technical field of screw shaft control, in particular to a pre-tightening, anti-loosening and balancing device for a screw shaft. Background technique [0002] The helical shaft in the prior art cannot pre-tighten the transmission of the wire rope, and the tightness cannot be adjusted after the wire rope is wound around the helical shaft; after the wire rope is wound, the helical shaft does not have a self-locking design. Loosening occurs due to the rotation of the screw; the existing helical shaft is designed to be supported at only one end, and after being subjected to the tension of the steel wire rope, there will be a problem with the perpendicularity of the axis. Contents of the invention [0003] The object of the present invention is to provide a pre-tightening, anti-loosening and balancing device for a helical shaft to solve the problem that the helical shaft in the prior art cannot pre-tighten and anti-loosen the...
