The utility model discloses assemble into an inner circle with retainer plate and activity circle, use long afterwards, if change, if change wearing and tearing that can, need not to change whole inner circle, guarantee that the ball weares and teares the inner circle for a long time and the circumstances of the frictional force increase that appears, and set up an axle sleeve, use to need not to change the outer lane long afterwards, can guarantee the precision as long as change the axle sleeve, life is more of a specified duration, and uses more economically.
Description
Technical field
The utility model belongs to field of machining, is specifically related to a kind of high-accuracy bearing.
Background technique
Bearing is in mechanical transmission course, play parts that are fixing and reduction load friction factor.Alternatively, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.
Existing bearing, owing to using long afterwards, ball can with the ball grooves friction of inner ring and outer ring, therefore rub long afterwards, rubbing surface just can be caused to lack smoothness, affect the rolling of ball, and then affect the service precision of whole bearing.If replacing bearing, then need to change whole bearing, user cost is higher.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of use long afterwards without the need to changing outer ring, as long as change axle sleeve can ensure precision, working life is more of a specified duration, and uses more cost effective high-accuracy bearing.
The utility model is achieved through the following technical solutions: a kind of high-accuracy bearing, comprise inner ring, outer ring and ball, described inner ring comprises retainer ring and active ring, described retainer ring outer wall is uniform is provided with four location inserted blocks, the centre of described active ring arranges a mounting hole, and described retainer ring is arranged in the middle mounting hole offered of active ring;
The inwall of described active ring just all arranges a slot to inserted block position, each location, described retainer ring is inserted by outside location inserted block and is arranged in the slot of active ring, the outer wall of described active ring is provided with the first ball grooves, the inwall of described outer ring is provided with a circle annular groove, install an axle sleeve in annular groove, the outer side surface of described axle sleeve and annular groove are fitted.
As preferred technological scheme, the outer wall of described axle sleeve is provided with the positioning block of more than a piece, and be provided with the quantity locating slot identical with positioning block in described annular groove, described axle sleeve is fixedly installed in the locating slot of annular groove by positioning block.
As preferred technological scheme, rectifying up and down of described axle sleeve all arranges a baffle plate to ball position.
As preferred technological scheme, described axle sleeve relative motion circle side is provided with the second ball grooves, and ball is arranged between the first ball grooves and the second ball grooves.
The beneficial effects of the utility model are: retainer ring and active ring are assembled into an inner ring by the utility model, use long afterwards, if changed, as long as change that piece of wearing and tearing, without the need to changing whole inner ring, guarantee ball long term wear inner ring and situation that the frictional force that occurs increases, and set up an axle sleeve, use long afterwards without the need to changing outer ring, as long as change axle sleeve can ensure precision, working life is more of a specified duration, and uses more economically.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the plan view of inner ring of the present utility model.
Embodiment
All features disclosed in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this specification (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
As depicted in figs. 1 and 2, the high-accuracy bearing of one of the present utility model, comprise inner ring, outer ring 2 and ball 4, described inner ring comprises retainer ring 3 and active ring 1, described retainer ring 3 outer wall is uniform is provided with four location inserted blocks 10, the centre of described active ring 1 arranges a mounting hole, and described retainer ring 3 is arranged in the middle mounting hole offered of active ring 1;
The inwall of described active ring 1 just all arranges a slot to inserted block 10 position, each location, described retainer ring 3 is inserted by outside location inserted block 10 and is arranged in the slot of active ring 1, the outer wall of described active ring 1 is provided with the first ball grooves 8, the inwall of described outer ring is provided with a circle annular groove, install an axle sleeve 6 in annular groove, outer side surface and the annular groove of described axle sleeve 6 are fitted.
Wherein, the outer wall of axle sleeve 6 is provided with the positioning block 5 of more than a piece, be provided with the locating slot that quantity is identical with positioning block in described annular groove, described axle sleeve 6 is fixedly installed in the locating slot of annular groove by positioning block 5, prevents axle sleeve rotating relative between outer ring after arranging positioning block.
Wherein, rectifying up and down of axle sleeve 6 all arranges a baffle plate 7 to ball position, and the arranging of this baffle plate 7 mainly plays a dust-proof effect, prevents because under harsh environments, dust enters in ball, affect service precision, increase working life.
Wherein, axle sleeve relative motion circle side is provided with the second ball grooves, and ball is arranged between the first ball grooves and the second ball grooves.
If the active ring excessive wear on inner ring, as long as now take out retainer ring and active ring, retainer ring relative motion circle is pulled out, then change one new, increase working life, saving cost.
The beneficial effects of the utility model are: retainer ring and active ring are assembled into an inner ring by the utility model, use long afterwards, if changed, as long as change that piece of wearing and tearing, without the need to changing whole inner ring, guarantee ball long term wear inner ring and situation that the frictional force that occurs increases, and set up an axle sleeve, use long afterwards without the need to changing outer ring, as long as change axle sleeve can ensure precision, working life is more of a specified duration, and uses more economically.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
