The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides a bearing pedestal, includes fixed baseplate and sets up in the axle sleeve at fixed baseplate center, the inner wall of axle sleeve is equipped with the bar groove, fixed baseplate's one end is equipped with the spacing arch of bearing axle sleeve, and one side of the other end is equipped with fixing device, fixing device including around fixed baseplate axle center evenly distributed's card put the piece and with the lock ring of card put a looks adaptation, its periphery of the fixed baseplate other end is equipped with the stroke recess that supplies the card to put the piece to slide, the card put the piece include with the fixture block that slides that forms recess looks adaptation and set up with the arc fixture block directly over the fixture block that slides, the periphery of arc fixture block is equipped with the arc recess, the arc recess is arranged in to lock ring cover, the lock ring is equipped with closed breach, and the border of closed breach is equipped with the extension arm of keeping.

Evenly distributed connecting ribs are arranged among the fixed base, the inner ring and the outer ring.

The shaft sleeve is in interference fit with the bearing seat, and the end face of the shaft sleeve is flush with the end face of the fixed base.

The side wall of the buckling ring is abutted to the side wall of the arc-shaped groove.

Owing to adopted above-mentioned technical scheme, a bearing frame, through setting up fixing device restriction axle sleeve and breaking away from the bearing frame, even axle sleeve and bearing frame break away from interference fit and also can ensure safety, the utility model discloses simple structure, simple to operate, the effectual problem that breaks away from of axle sleeve of having solved.

Detailed Description

The present invention will be described in more detail with reference to the following examples, which are illustrated in the accompanying drawings. This example is merely a description of the best mode of carrying out the invention and is not intended to limit the scope of the invention in any way.

As shown in fig. 1 to 3, a bearing seat comprises a fixed base 1 and a shaft sleeve 2 arranged at the center of the fixed base 1, wherein the inner wall of the shaft sleeve 2 is provided with a strip-shaped groove 21, one end of the fixed base 1 is provided with a limit protrusion 11 for supporting the shaft sleeve 2, one side of the other end is provided with a fixing device, the fixing device comprises clamping pieces 3 uniformly distributed around the axis of the fixed base 1 and a snap ring 4 matched with the clamping pieces 3, the periphery of the other end of the fixed base 1 is provided with a stroke groove 12 for the clamping pieces 3 to slide, the clamping pieces 3 comprise sliding blocks 31 matched with the formed grooves and arc blocks 32 arranged right above the sliding blocks 31, the periphery of the arc blocks 32 is provided with an arc groove 33, the snap ring 4 is sleeved in the arc groove 33, the snap ring 4 is provided with a closed gap, the edge of the closed gap is provided with an extension arm 41 extending away from the periphery of the snap ring 4, the extension arms 41 are fixed by screws. The strip-shaped groove 21 is used for inserting a key when the shaft sleeve 2 is connected with a shaft.

Evenly distributed connecting ribs 13 are arranged between the fixed base 1 and the inner ring and the outer ring.

The shaft sleeve 2 is in interference fit with the bearing seat, and the end face of the shaft sleeve 2 is flush with the end face of the fixed base 1.

The side wall of the buckling ring 4 is abutted against the side wall of the arc-shaped groove 33.

The specific working principle is as follows:

when axle sleeve 2 inserts in the bearing frame and interference fit with it, 2 one end of axle sleeve is contradicted spacing arch 11, other end terminal surface and bearing frame terminal surface parallel and level, rethread fixing device restriction axle sleeve 2 breaks away from the bearing frame, specifically, insert in stroke recess 12 and remove to fixed baseplate 1's axle center direction along stroke recess 12 through the fixture block 31 that slides with piece 3 is put to the card, the inner wall of fixed baseplate 1 is covered until the inner wall of arc fixture block 32, arrange 4 covers of lock ring in arc recess 33 again, and through the fixed extension arm 41 of screwed connection, avoid sliding fixture block 31 to remove, the piece 3 cooperation spacing arch 11 of card is put like this and is restricted axle sleeve 2 in fixed baseplate 1.

Owing to adopted above-mentioned technical scheme, a bearing frame, through setting up fixing device restriction axle sleeve 2 and break away from the bearing frame, even axle sleeve 2 and bearing frame break away from interference fit and also can ensure safety, the utility model discloses simple structure, simple to operate, the effectual axle sleeve 2 that has solved breaks away from the problem.

It is to be understood that the above examples are merely illustrative for clarity of description and are not limiting on the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are intended to be within the scope of the invention.
