Abstract
A kind of shaftless mute castor of single-bearing, including the cyclic annular foreign steamer of main body, bearing, neck bush and two, main body and cyclic annular foreign steamer relatively rotate, and main body is arranged in the outer ring of bearing；Two cyclic annular foreign steamers are separately positioned on bearing both sides；Liner is set between cyclic annular foreign steamer inner ring and the inner ring of bearing.Neck bush width is more than bearing inner race width.Neck bush is spliced by two bush rings, and bush ring outer round surface has step, for being limited to bearing.Two cyclic annular foreign steamer inner ring walls are mutually spliced by male and female buckle.The bearing set in one is only used only in the utility model, reduces whole cost.Bearing is wrapped between main body and neck bush, is not exposed directly, be ensure that the rotation flexibility of bearing.The stress of both sides ring-type foreign steamer is passed to bearing by the neck bush for being more than bearing width by width, has been disperseed the stress of both sides ring-type foreign steamer, has been extended the cyclic annular foreign steamer service life.Both sides ring-type foreign steamer uses splicing construction, is completely embedded, convenient for assembling.
Description
Technical field
The utility model is related to a kind of shaftless mute castors of single-bearing applied on office equipment, equipment, means of transport.
Background technology
Shaftless mute castor has many advantages, such as that steering is smooth, flexible, and occupies little space.Main body and cyclic annular foreign steamer
It relatively rotates.In the prior art in order to ensure the rotation of cyclic annular foreign steamer flexibility and stress uniformity, in cyclic annular foreign steamer and master
Two bearings are set between body.But due to bearing higher price, improve the relative price of castor.In addition, bearing face is sudden and violent
It is exposed, gets rusty easily in a humid environment, influence the flexibility of castor rotation.
Invention content
The utility model aim is the defect for the shaftless mute castor of existing duplex bearing, provides a kind of at low cost, turns
It is dynamic flexible, the shaftless mute castor of bearing single-bearing with long service life.
The utility model to achieve the above object, adopts the following technical scheme that：
A kind of shaftless mute castor of single-bearing, including main body, bearing, the cyclic annular foreign steamers of neck bush and two, the main body and
Cyclic annular foreign steamer relatively rotates, it is characterised in that：The main body is arranged in the outer ring of the bearing；Two cyclic annular foreign steamer difference
It is arranged in the bearing both sides；The liner is set between the cyclic annular foreign steamer inner ring and the inner ring of bearing.
It is further characterized by：The neck bush width is more than bearing inner race width.
Further：The neck bush is spliced by two bush rings, and the bush ring outer round surface has step, is used
It is limited in bearing.
Preferably：Two cyclic annular foreign steamer inner ring walls are mutually spliced by male and female buckle.
Two cyclic annular foreign steamer inner ring wall stitching portion width are not more than the neck bush width.
It is further characterized in that：It is provided with brake gear in the main body.
Preferably：The brake gear includes the multiple teeth being arranged in the arbitrary side of the non-rolling surface of the cyclic annular foreign steamer
Item forms lock groove between two neighboring rack；Push type arrangement of clutch, the push type clutch dress are provided in the main body
It sets one end and is connected with locking rod, the locking rod is driven by the push type arrangement of clutch, moved along the lock groove.
Push type arrangement of clutch one end is connected to the middle part of the locking rod, and the locking rod both ends are respectively along two
The lock groove of cyclic annular foreign steamer moves.
The bearing set in one is only used only in the utility model, reduces whole cost.Bearing is wrapped in main body and interior
Between bushing, does not expose directly, ensure that the rotation flexibility of bearing.It is more than the neck bush of bearing width by both sides by width
The stress of cyclic annular foreign steamer passes to bearing, has disperseed the stress of both sides ring-type foreign steamer, extends the cyclic annular foreign steamer service life.Both sides are cyclic annular
Foreign steamer uses splicing construction, is completely embedded, convenient for assembling.
Description of the drawings
Fig. 1 is the utility model outline structural diagram.
Fig. 2 is the utility model section figure.
Fig. 3 is brake device structure schematic diagram.
Specific implementation mode
As shown in Figure 1, 2, the shaftless mute castor of a kind of single-bearing, including main body 1, bearing 4, neck bush 3 and two ring-types
Foreign steamer 2, main body 1 and cyclic annular foreign steamer 2 relatively rotate, and main body 1 is arranged in the outer ring of bearing 4；Two cyclic annular foreign steamers 2 are separately positioned on
4 both sides of bearing；Neck bush 3 is arranged between 2 inner ring of cyclic annular foreign steamer and the inner ring of bearing 4.
3 width of neck bush is more than 4 inner race width of bearing, increases the contact area with cyclic annular 2 inner ring of foreign steamer, in order to
Disperse the stress of both sides ring-type foreign steamer 2, and stress is transferred to bearing 4.
Neck bush 3 is spliced by two bush rings, and bush ring outer round surface has step, for limiting bearing 4
Position.2 inner ring wall of cyclic annular foreign steamer is mutually spliced by male and female buckle.Using splicing construction convenient for assembling.
Two 2 inner ring wall stitching portion width of cyclic annular foreign steamer are not more than the width of neck bush 3.To ensure that stitching portion can obtain
To the complete support of neck bush 3, weak stitching portion cracking is prevented, the service life of cyclic annular foreign steamer 2 is extended.
As shown in Figure 1,3, it is provided with brake gear 5 in main body 2.Brake gear 5 includes being arranged in 2 medial surface of cyclic annular foreign steamer
Multiple racks 52, form lock groove between two neighboring rack 52；It is provided with push type arrangement of clutch 51 in main body 2, presses
51 one end of formula arrangement of clutch is connected with locking rod 53, and locking rod 53 is driven by push type arrangement of clutch 51, moved along lock groove.It presses
51 one end of pressure type arrangement of clutch is connected to the middle part of locking rod 53, and 53 both ends of locking rod are respectively along the locking of two cyclic annular foreign steamers 2
Slot moves.
