Abstract
The utility model discloses a closely connected bearing. The closely connected bearing comprises a bearing outer ring, a bearing inner ring and rolling elements which are uniformly distributed between the bearing inner ring and the bearing outer ring, wherein the upper end of the bearing inner ring is protruded from the bearing outer ring; at least two gaps are uniformly formed at the upper end of the bearing inner ring; and a fastening device is sleeved on the outer side of the upper end of the bearing inner ring, and comprises an annular clamping sleeve with a radial screw hole and a screw which is matched with the screw hole. When the bearing is used, the screw is tightened to ensure that the screw extrudes the upper end of the bearing inner ring, and the bearing inner ring is elastically deformed and is firmly pressed against a shaft in the bearing inner ring, so that mechanical faults can be reduced, and the service life of the bearing is greatly prolonged.
Description
Technical field
The utility model relates to a kind of bearing, is meant a kind of novel bearing that can axle be pushed against especially.
Background technique
Bearing (" Bearing ", Japan's person " axle receives ") is in mechanical transmission course, to work the parts of fixing and reducing the load friction factor.Also we can say, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in the power transmission process.Bearing is a kind of very important component in the contemporary machinery.Its major function is the supported mechanical solid of rotation, in order to the mechanical load friction factor of reduction equipment in transmission process.Press the difference of motor element frictional property, bearing can be divided into two types on rolling bearing and sliding bearing.
Bearing generally include bearing outer ring, bearing inner race and be uniformly distributed in bearing inner race and bearing outer ring between rolling element; Axle is installed in the bearing inner race during use, can run into such problem usually during actual the use, because there are the gap in axle and bearing inner race; Be bearing inner race and axle butt defective tightness; Axle takes place loosening in movement process, and this will cause mechanical failure, and influences working life.
The model utility content
The utility model provides a kind of connection bearing closely, and its purpose is to overcome the above-mentioned defective that existing technology exists.
The technological scheme of the utility model is following:
A kind of connection is bearing closely; Comprise bearing outer ring, bearing inner race and be uniformly distributed in bearing inner race and bearing outer ring between rolling element; The upper end portion of said bearing inner race protrudes from bearing outer ring; And the upper end portion of bearing inner race evenly offers at least 2 breach, and the outside of said upper end portion is arranged with securing means, and this securing means comprises and has radially the ring cutting ferrule of screw and the screw rod that is used with above-mentioned screw.
As the improvement of the utility model, be evenly distributed with 3 screws on the said ring cutting ferrule.Screw rod is connected to bearing inner race evenly distributedly, can make the bearing inner race stress balance.
As the further improvement of the utility model, the upper end portion of said bearing inner race evenly offers 6 breach, and the width of said breach is 1mm-3mm, and the degree of depth of said breach is 8mm-12mm.
Can know by above-mentioned description the utility model; Compare with existing technology; The advantage of the utility model is: the screw rod of screwing during use makes the upper end portion of screw rod extruding bearing inner race; The bearing inner race resiliently deformable and with in the bearing inner race the axle firmly push against, can not only reduce mechanical failure, and greatly prolong the working life of bearing.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
The embodiment of the utility model is described with reference to the accompanying drawings.
With reference to Fig. 1; A kind of connection is bearing closely; Comprise bearing outer ring 1, bearing inner race 2 and be uniformly distributed in bearing inner race 2 and the rolling element of 1 of bearing outer ring (owing to not drawing in the cause chart of visual angle), the upper end portion 21 of said bearing inner race 2 protrudes from bearing outer ring 1, and the upper end portion 21 of bearing inner race 2 evenly offers four breach 211; The width of above-mentioned breach 211 is 1mm-3mm, and the degree of depth of said breach 211 is 8mm-12mm.The outside of upper end portion 21 is arranged with securing means.Said securing means comprises ring cutting ferrule 3 and the screw rod 4 that cooperates with bearing inner race 2, evenly offers three screws 31 (owing to reason another screw in visual angle does not draw) on the said ring cutting ferrule 3, and said screw rod 4 is arranged in above-mentioned screw correspondingly.
Rotating screw bolt 4 during use; The upper end portion 21 that three screw rods 4 push bearing inner race 2 simultaneously makes bearing inner race 2 resiliently deformables and the axle (not drawing among the figure) in the bearing inner race 2 is firmly pushed against; Can not only reduce mechanical failure, and greatly prolong the working life of bearing.
The above-mentioned embodiment that is merely the utility model, but the design concept of the utility model is not limited thereto allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
Claims (3)
1. one kind connects bearing closely; Comprise bearing outer ring, bearing inner race and be uniformly distributed in bearing inner race and bearing outer ring between rolling element; It is characterized in that: the upper end portion of said bearing inner race protrudes from bearing outer ring; And the upper end portion of bearing inner race evenly offers at least 2 breach, and the outside of said upper end portion is arranged with securing means, and this securing means comprises and has radially the ring cutting ferrule of screw and the screw rod that is used with above-mentioned screw.
2. a kind of connection as claimed in claim 1 is bearing closely, it is characterized in that: be evenly distributed with 3 screws on the said ring cutting ferrule.
3. according to claim 1 or claim 2 a kind of connection bearing closely, it is characterized in that: the upper end portion of said bearing inner race evenly offers 6 breach, and the width of said breach is 1mm-3mm, and the degree of depth of said breach is 8mm-12mm.
