Description

Technical field:

[0001] The utility model relates to the technical field of bearing installation equipment, and more specifically to a tool for installing a locking nut. Background technology:

[0002] When rolling bearings are fixed and locked on shafts with nuts, and when nuts are used to fix and lock the ends of shafts, problems such as the nut diameter being too large for installation and the nut installation radial space being too small for installation are often encountered;

[0003] When encountering the above problems, it is impossible to use existing wrenches and other tools to rotate the nut for installation. The only way is to insert the two rods into the two slots on the sides of the nut, and then hold the two rods by hand to rotate the nut. The rotation is troublesome and inefficient, and the rods are easily removed from the slots, affecting the screw connection effect. Utility model content:

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a tool for installing a locking nut, which can insert all positioning rods into the corresponding side slots of the locking nut. The locking nut can be locked and fixed by rotating the main annular plate. It is not affected by the surrounding operating space, so that it can meet the requirements of operation in various operating environments.

[0005] The solution of the utility model to solve the technical problem is:

[0006] A tool for installing a locking nut, comprising a rotating shaft, a rolling bearing is installed on the outer wall of the rotating shaft, a threaded rotating part with an outer diameter smaller than that of the rotating shaft is formed in the middle of the front end surface of the rotating shaft, and the locking nut is threadedly connected to the threaded rotating part;

[0007] The outer wall of the locking nut is formed with a plurality of side slots extending front to back, and the positioning rods are inserted into the corresponding side slots. The front ends of all the positioning rods extend out of the front end surfaces of all the side slots and are fixed on the rear end surface of the same main body annular plate, and a plurality of extension rod bodies are fixed on the outer side of the main body annular plate.

[0008] The side wall of the front end of the positioning rod is welded and fixed with a plurality of side reinforcing plates, and the front wall surface of the side reinforcing plate is fixed on the rear end surface of the main body annular plate. The side reinforcing plate is used to strengthen the connection firmness between the positioning rod and the main body annular plate.

[0009] A plurality of side reinforcing ribs are fixed on the outer side wall of the inner end of the extension rod body, and the inner ends of the side reinforcing ribs are welded and fixed on the outer side wall of the main body annular plate. The side reinforcing ribs are used to strengthen the connection effect between the extension rod body and the main body annular plate.

[0010] The outstanding effects of the utility model are:

[0011] Compared with the prior art, it can insert all positioning rods into the corresponding side slots of the locking nut. By rotating the main annular plate, the locking nut can be locked and fixed. It is not affected by the surrounding operating space, so that it can meet the operation requirements in various operating environments. Description of the drawings:

[0015] Figure 4 It is a left view of the utility model. Specific implementation method:

[0016] For example, see Figures 1 to 4 As shown, a tool for installing a locking nut comprises a rotating shaft 100, a rear end of the rotating shaft 100 is formed with a rear end main rotating shaft portion whose outer diameter is larger than that of the rotating shaft 100, a supporting shell plate 1000 is inserted and sleeved on the rotating shaft 100, a stepped through hole is formed in the middle of the supporting shell plate 1000, the rear end of which is a small diameter hole section and the front end is a large diameter hole section, the rotating shaft 100 is inserted and sleeved in the stepped through hole, a rolling bearing 200 is installed in the large diameter hole section, the outer side wall of the outer ring of the rolling bearing 200 is pressed against the inner side wall of the large diameter hole section, the rear end face of the outer ring is pressed against the rear end face of the large diameter hole section, the inner side wall of the inner ring of the rolling bearing 200 is pressed against the outer side wall of the rotating shaft 100, a screw-connected rotating portion 101 whose outer diameter is smaller than that of the rotating shaft 100 is formed in the middle of the front end face of the rotating shaft 100, and a locking nut 300 is screwed on the screw-connected rotating portion 101;

[0017] In this embodiment, two locking nuts 300 are screwed on the threaded rotating part 101, and a plurality of side slots 301 penetrating front and back are formed on the outer wall of the locking nuts 300. The side slots 301 of the two locking nuts 300 are first aligned, and each positioning rod 10 is inserted into the two corresponding side slots 301 of the two locking nuts 300. The front ends of all positioning rods 10 extend out of the front end faces of all side slots 301 and are fixed on the rear end face of the same main body annular plate 20. A plurality of extension rod bodies 21 are fixed on the outer side of the main body annular plate 20. It only needs to rotate the extension rod body 21 to rotate the main annular plate 20 to realize the rotation of the two locking nuts 300, so that the rear end face of the locking nut 300 at the rear end is pressed against the front end face of the inner ring of the rolling bearing 200 to achieve tightening. At this time, if the front locking nut 300 is not pressed against the rear locking nut 300, all the positioning rods 10 can be moved forward by one position so that they are just inserted into the side slot 301 of the front locking nut 300, and then, the main annular plate 20 is rotated so that the rear end face of the previous locking nut 300 is pressed against the front end face of the rear locking nut 300 to achieve locking.

[0018] Furthermore, the middle parts of all the positioning rods 10 are inserted into the corresponding insertion holes of the middle positioning annular plate 30, and the middle outer walls of the positioning rods 10 are tightly attached to the inner walls of the corresponding through holes and are fixed by welding.

[0019] A plurality of side reinforcing plates 1 are welded and fixed to the side wall of the front end of the positioning rod 10 , and the front wall surface of the side reinforcing plate 1 is fixed to the rear end surface of the main body annular plate 20 .

[0020] A plurality of side reinforcing ribs 2 are fixed on the outer side wall of the inner end of the extension rod body 21 , and the inner ends of the side reinforcing ribs 2 are welded and fixed on the outer side wall of the main body annular plate 20 .
