Abstract
The utility model discloses an anti-loosing screw nut used for screw thread connection and fastening of an electromechanical device. The utility model is characterized in that a chamfered groove is arranged on a screw nut (1), a stop roller (2) is installed in the chamfered groove, the outside of the screw nut (1) is sheathed with an outer ring (3), a key tooth of an inner hole of a retaining ring (5) matches with a key slot on the screw rod, a fixed rod (4) is arranged on an outer edge of the retaining ring (5) and the fixed rod is fixed with an outer ring through a screw nail. The utility model effectively solves the easy-loosing problem of the screw nut in the process of the screw thread connection of a large electromechanical device, the safe running of the electromechanical device is guaranteed and the service life is prolonged.
Description
The utility model relates to a kind of fastening piece, particularly a kind of nut of becoming flexible of preventing.
Fix or axis head nut fixedly the time at the stone bolt of main equipment, spindle nose up and down as straightening machine in the metallurgy industry, the stone bolt of main mill, heavy lift body of the tower connecting bolt etc., be to prevent that because the nut loosening that vibration causes way commonly used is to add a nut to become flexible preventing on tightening nut.The reliability of this way is relatively poor, withdraw from because the high vibration of equipment tends to make two nuts to become flexible simultaneously, so that equipment is damaged.
The purpose of this utility model provide a kind of can be reliably fastening and nut that can in vibration, not become flexible.
The purpose of this utility model is achieved in that and has chamfered groove on nut, and the stop roller is housed in the chamfered groove, and the nut outside is with the outer ring.The key tooth of back-up ring endoporus matches with the keyway on the threaded stem, on the back-up ring outer rim fixing rod is housed, and fixing rod is fixed by screw and outer ring.
The utility model compared with prior art has fastening reliable, has both made the also unlikely loosening advantage of high vibration.
Elaborate below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation
Fig. 2 is the left view of Fig. 1
Fig. 3 is along A-A face view
Have two chamfered grooves among the figure on the nut 1, be placed with stop roller 2 in the chamfered groove, nut 1 outside is with outer ring 3.The key tooth of back-up ring 5 endoporus matches with the keyway of threaded stem, has two breach on the outer rim of back-up ring 5, installs and fixes bar 4 in the breach, and fixing rod 4 the other ends are screwed into the on the outer ring 3.
Using method: the nut screwing clamping that at first will be with the outer ring is on threaded stem (can be bolt or threaded spindle nose), and the stop roller of packing in its chamfered groove is loaded onto back-up ring then, at last fixing rod is tightened on the outer ring.Because chamfered groove and stop roller construction make nut to turn clockwise, be subjected to the obstruction of stop roller, outer ring, fixing rod and back-up ring during the inhour rotation, thereby guaranteed that not being fastenedly connected of nut can become flexible.
Claims (1)
