Abstract
The utility model discloses a round nut preloader, including the preloader body, this internal through -hole that is equipped with of preloader, the slot has been offered in the step hole of through -hole for comprising macropore and aperture on the terminal surface of the macropore place end of preloader body, the quantity of slot and position all with the round nut on the quantity and the position of slot corresponding, the slot in -connection has the inserted block of the ditch inslot that can insert the round nut, be connected with on the preloader body and be used for ordering about the rotation of preloader body then the drive lies in big downthehole round nut pivoted handle. The round nut preloader simple structure of this structure, no matter convenient to use locks or dismantles the round nut, can not cause the damage to the round nut to the safe and reliable during use.
Description
Technical field
The utility model relates to a kind of round nut that drives and rotates the round nut preloader of then being locked.
Background technology
Existing bearing round nut fastening means is mainly: hand hammer adds welding tooling and directly knocks round nut groove place and carry out fastening.Mainly there is following shortcoming in aforesaid way.One, owing to directly knocking, there are iron filings and fly phenomenon of spouting, if enter bearing cavity, damage ball, causes bearing to exist and damages hidden danger, reduce service life; Two, there is potential safety hazard, when especially large bearing assemble knocks, energy one is not concentrated, and very likely security incident occurs; Three, exert all one's strength in a bit owing to knocking to concentrate, very easily groove place is destroyed, cause round nut to be out of shape, affect presentation quality and round nut service life; Four, strengthen field stripping difficulty, increase the Probability of security incident, and more serious to the damage of round nut, reduce the access times of round nut, reduction of service life.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of convenience and carries out round nut preloader that is fastening and dismounting, to overcome above-mentioned defect to round nut.
For solving the problems of the technologies described above, the utility model provides a kind of round nut preloader of following structure, its design feature is: comprise preloader body, through hole is provided with in preloader body, described through hole is the stepped hole be made up of macropore and aperture, the end face of the macropore place end of preloader body offers slot, and the quantity of described slot and position are all corresponding with the quantity of the groove on round nut and position; The inserted block that can insert in the groove of round nut is connected with in described slot; Preloader body is connected with and rotates for ordering about preloader body the handle then driving the round nut being positioned at macropore to rotate.
For the ease of the replacing of inserted block, described inserted block is connected by screw in described slot.
Prevent from during in order to grip skidding, on described handle, roll extrusion has decorative pattern.
Described inserted block comprises rectangular inserted block body, and the outer end of inserted block body is provided with the guide part in the groove being beneficial to inserted block insertion round nut.
The relative two sides of described guide part are inclined plane, thus make the thickness of guide part by outer and interior thickening gradually.
The respective side of described inclined plane and inserted block body seamlessly transits, thus the two sides that inserted block is matched with the groove of round nut are formed by vertical section and tilting section.
Occupation mode of the present utility model is as follows: be first spun in bearing installation shaft with hand by round nut, then by the through hole of preloader body by preloader body sleeve in bearing installation shaft, bearing installation shaft is spread out of from the aperture of through hole, makes round nut be positioned at the macropore of through hole and make inserted block insert the groove of round nut; Rotated by handle drives preloader body, under the effect of inserted block, round nut is also along with rotation, and along with the continuous rotation of preloader body, round nut is just locked, and locks and completely to be taken off from bearing installation shaft by round nut preloader.Said process is the locking process of round nut, same reason, is beneficial to round nut preloader and also the round nut of locking can be taken off.
The utility model has the advantage of: structure is simple, easy to use, no matter locks or dismantles round nut, all can not cause damage to round nut, and safe and reliable when using.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the top view after Fig. 1 removes inserted block;
Fig. 4 is the structural representation of inserted block.
Detailed description of the invention
With reference to shown in Fig. 1, Fig. 2 and Fig. 3, round nut preloader comprises preloader body 1, and preloader body 1 is a columned revolving body, is provided with axial through hole 2 in preloader body 1, and described through hole 2 is the stepped hole be made up of macropore 21 and aperture 22; The radial and axial size of macropore 21 is corresponding to the radial and axial size of round nut, can hold round nut to make macropore 21; The radial dimension of aperture 22 is corresponding to the radial dimension of bearing installation shaft, can pass aperture 22 to make bearing installation shaft.The end face of the macropore 21 place end of round nut preloader body 1 offers slot 3; The quantity of described slot 3 and position are all corresponding with the quantity of the groove on round nut and position, and namely the quantity of slot 3 is identical with the quantity of the groove on round nut, the position one_to_one corresponding of the groove on the position of described slot 3 and round nut.The bottom land of described slot 3 is provided with screwed hole 9, is connected with the inserted block 4 that can insert in the groove of round nut in described slot 3; Inserted block 4 passes through through inserted block 4 and the screw 7 be screwed onto in described screwed hole 9 is fixed in slot 3.Preloader body 1 is connected with and rotates for ordering about preloader body 1 handle 5 then driving the round nut being positioned at macropore 21 to rotate.On described handle 5, roll extrusion has decorative pattern 6.
See figures.1.and.2 and emphasis with reference to Fig. 4, described inserted block 4 comprises rectangular inserted block body 41, establishes the screw hole 8 passed for described screw 7 in inserted block body 41, and the outer end of inserted block body 41 is provided with and is beneficial to inserted block 4 and inserts guide part 42 in the groove of round nut.The relative two sides of described guide part 42 are inclined plane, thus make the thickness of guide part 42 by outer and interior thickening gradually; The respective side of described inclined plane and inserted block body 41 seamlessly transits, thus the two sides that inserted block 4 is matched with the groove of round nut are formed by vertical section and tilting section.
