Sleeve is supported with screw rod away from one end of bearing pin, and the termination of screw rod is installed with gear, gear and gear shaft engagement fit, and the reference diameter of gear is greater than the reference diameter of gear shaft, and the free end of gear shaft is provided with handwheel;
The other end of screw rod is connected with nut thread, and nut is connected with the end of bearing pin by attachment screw.
Described screw rod is the screw rod of band trapezoidal thread.
Sleeve is connected with inner end cap by flange away from one end of bearing pin, is provided with a rolling bearing between inner end cap and screw rod, and end face and the gland of inner end cap are connected by screw, and is provided with another rolling bearing in gland and between screw rod.
Inner end cap is also connected with outer end cap by flange, and the termination of screw rod is bearing on outer end cap by self-lubricating bearing, and gear shaft two ends are bearing between outer end cap and inner end cap by self-lubricating bearing.
Described bearing pin axle center has the through hole for holding screw rod, has groove on the surface of bearing pin, with dog screw location, does not rotate when bearing pin moves; Also be provided with balancing weight at bearing pin away from the other end of sleeve, balancing weight axle center has passage.
One provided by the invention is laborsaving moves shaft device, by arrange gear train and and bolt and nut mechanism, the problem that the large-scale headstock gear movable pulley device of prior art wears axle difficulty can be overcome, alleviate manual rotation and move strength needed for shaft device handwheel, do not need to adopt other instrument reliably to be penetrated by bearing pin in gate lifting eye hole, improve operability and the reliability of headstock gear, reduce labour intensity, improve field labor condition.
