In order to solve above-mentioned technical problem, this utility model provides one can reduce large-scale power transmission shaft manufacture difficulty, shortens large-scale power transmission shaft manufacturing schedule, the draw bail of cost-effective large-scale power transmission shaft.
The technical solution adopted in the utility model is: include sleeve pipe, two springs, two snap closes and two power transmission shafts, on two described power transmission shafts relative to one end be respectively equipped with screw thread, the thread rotary orientation on two power transmission shafts is contrary；Two described springs respectively with the threaded engagement on two power transmission shafts, two springs are fixed on two power transmission shafts by snap close respectively；Described casing tube internal hole be respectively arranged at two ends with female thread, coordinated with two springs respectively by female thread.
In the draw bail of above-mentioned large-scale power transmission shaft, described snap close include upper half snap close and lower half snap close, upper half snap close and lower half snap close all in semi-circular, diameter is identical；Upper half snap close is respectively arranged at two ends with screwed hole, and corresponding to screwed hole, lower half snap close is provided with screw hole, and upper half snap close is connected by screw into a loop configuration with lower half snap close.
In the draw bail of above-mentioned large-scale power transmission shaft, the described screw thread on power transmission shaft and the female thread of sleeve pipe all use round thread.
In the draw bail of above-mentioned large-scale power transmission shaft, one end end face that two described power transmission shafts are relative being respectively equipped with groove, the lower half snap close of described snap close is provided with groove, and the two ends of spring are respectively provided in the groove of lower half snap close and the groove of end part of driving shaft.
Compared with prior art, the beneficial effects of the utility model are:
Power transmission shaft is divided into multistage by this utility model, is linked to be a power transmission shaft, can reduce the requirement to equipment of the large-scale power transmission shaft, reduce power transmission shaft heat treatment and mechanical processing difficulty, saved cost in the way of connection, shortens the making duration；This utility model bonding strength is high, can disperse at power transmission shaft screw thread to stress to protect power transmission shaft; this utility model has bonding strength height, screw thread axial stress can be disperseed with the advantage protecting power transmission shaft round thread; whole axle will not be caused to scrap; only need to change spring or sleeve pipe and be unlikely whole axle and scrap when dismounting and maintenance, reduce manufacture maintenance cost.
