Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1, the utility model provides the following technical solutions:

a fastening sleeve easy to disassemble comprises a fastening bush, a fastening nut, a fastening washer and a self-disassembling mechanism, wherein the fastening nut and the fastening washer are fixed on the fastening bush, one side surface of the fastening bush is provided with an accommodating through cavity 104 penetrating through the fastening bush, the fastening bush comprises a fastening wall section 102 which is in a conical ring shape and is matched with an inner ring of a bearing 5, a threaded wall section 101 fixed on one side surface of the fastening wall section 102 and a fixed wall section 103 fixed on the other side of the fastening wall section 102, the fastening nut is provided with an inner thread matched with the threaded wall section 101, the fastening washer is sleeved and fixed on the threaded wall section 101, one side surface of the fastening washer is in contact fit with the side surface of the fastening nut, the other side surface of the fastening washer is in contact fit with the side surface of the bearing 5, and the self-disassembling; the mechanism of shirking by oneself includes solid fixed ring 201, resilience subassembly and cushion washer 203, gu fixed ring 201 overlaps to be established and is fixed in on the fixed wall section 103, gu fixed ring 201's interior arc side contacts the laminating with fixed wall section 103 side, the resilience subassembly includes a plurality of spring telescopic links 202, spring telescopic link 202 distributes around solid fixed ring 201 axis circumference, the one end of spring telescopic link 202 and a fixed ring 201's a side fixed connection, spring telescopic link 202's the other end and cushion washer 203 fixed connection, a side of cushion washer 203 offsets with the inner circle contact of bearing 5.

The fastening sleeve can be quickly and automatically detached from the bearing 5 in the detaching process through the self-detaching mechanism, so that the detaching process of the whole fastening sleeve is facilitated. Specifically, the adapter sleeve is generally used for fastening the conical surface bearing 5, when the conical surface bearing 5 enters the conical annular adapter sleeve, because the radial play of the bearing 5 is reduced due to the expansion of the inner ring, the radial play is adjusted by controlling the distance of the bearing 5 pressing the conical matching surface, and finally the fixed matching of the bearing 5 and the adapter sleeve is completed by screwing the adapter nut, after the matching of the bearing 5 and the adapter sleeve is completed, the spring telescopic rod 202 is compressed between the buffer gasket and the fixing ring 201, so that the buffer gasket is contacted and abutted against the bearing 5, thereby the trend of self-separation is generated between the bearing 5 and the adapter sleeve, the buffer gasket has the function of avoiding the spring telescopic rod 202 from being directly contacted with the inner ring of the bearing 5, the stress pressure intensity with the inner ring of the bearing 5 can also be reduced, the bearing 5 is protected, the service life of the bearing 5 is prolonged, when the adapter sleeve needs to be disassembled and maintained, only the lock nut, the bearing 5 will automatically detach from the adapter sleeve under this tendency of separation by the telescopic spring rod 202, facilitating the detachment of the entire adapter sleeve.

Further, as shown in fig. 2, a limiting convex edge 204 is fixed at one end of the side surface of the fixed wall section 103, the other side surface of the fixed ring 201 is in contact fit with the limiting convex edge 204, a plurality of guide grooves are arranged on the arc-shaped side surface of the fixed wall section 103, and a plurality of guide convex strips 205 matched with the guide grooves are fixed on the inner arc-shaped side surface of the fixed ring 201; spacing protruding edge 204 is convenient with solid fixed ring 201 axial spacing fixed, in practical application, the mechanism shirks by oneself that uses solid fixed ring 201 as the main part is fixed with the one end of threaded wall section 101 from tight fixed sleeve and establishes toward other end direction cover, finally, stop in spacing protruding edge 204 one side position, spacing protruding edge 204 face and solid fixed ring 201 side contact laminating, gu fixed ring 201 obtains axial fixity, the cooperation of direction recess and direction sand grip 205, gu fixed ring 201 carries out radial fixation on tight fixed bush, prevent solid fixed ring 201 not hard up, in order to make spring telescopic link 202 produce conflict pressure better.

Furthermore, the fastening nut is a round nut, the arc-shaped side face of the fastening nut is provided with a plurality of locking grooves matched with the round wrench, the round nut is a common locking nut 3 on the market and is commonly used for axially fixing the bearing 5, and the locking nut has the advantages of compact structure and reliable locking matching.

Further, tightly decide the packing ring and include straight wall section 401 and be conical deformation wall section 402, deformation wall section 402 encircles and establishes on being fixed in straight wall section 401, be equipped with a plurality of deformation clearances around deformation wall section 402 center pin circumference distribution on the deformation wall section 402, the side of straight wall section 401 contacts the laminating with the side of bearing 5 inner circle, the side of deformation wall section 402 contacts with the side of tightly deciding the nut and offsets, based on this design, tightly decide the packing ring and screw up the in-process at lock nut 3 and produce elastic deformation, make it offset with bearing 5 contact, the area of contact with bearing 5 has been reduced, and play certain locking cushioning effect, further protect bearing 5.

Furthermore, a rubber layer is laid on one side surface of the buffer gasket 203, which is in contact with the bearing 5, and the rubber layer has good buffer characteristics, so that the buffer effect of the spring telescopic rod 202 on the stress of the bearing 5 is improved.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention. The present invention is not to be limited by the specific embodiments disclosed herein, and other embodiments that fall within the scope of the claims of the present application are intended to be within the scope of the present invention.
