Description

A kind of bearing with dust cap

Technical field

It the utility model is related to field of bearings, more particularly to a kind of bearing with dust cap.

Background technology

Bearing is a kind of important spare part in contemporary plant equipment, and its major function is the mechanical rotary body of support, is reduced Coefficient of friction in its motion process, and ensure its rotating accuracy.Bearing be by outer ring, inner ring, rolling element, retainer, sealing, Six big part of lubricating oil forms.Seal just includes dust cap, and dust cap is a circular cowling, is generally stamped to form by metal sheet, Be fixed on the lasso or packing ring of bearing, and extend towards another lasso or packing ring, cover bearing interior space, but not with separately One lasso or washer contacts.

Existing bearing dustproof cover structure is more complicated, and installation dust cap inconvenience is, it is necessary to by special installation tool Could install and fix dust cap, greatly affected bearing equipment dust cap efficiency, and dust cap typically with outer ring or Inner ring leaves very big space, these space strong influences dust-proof effect of dust cap.

Utility model content

In view of the above-mentioned state of the art, technical problem to be solved in the utility model is that providing a kind of carry prevents The bearing of dirt lid, dust cap good dustproof effect, dust cap steadiness is good, and install convenient is rapid.

Technical scheme is used by the utility model solves above-mentioned technical problem：

A kind of bearing with dust cap, including outer ring, inner ring, and the retainer between outer ring and inner ring, Retainer is enclosed with steel ball, and dust cap is provided between the outer ring of retainer both sides and inner ring, and dust cap is erected in locating slot, fixed Position groove includes the first locating slot on the madial wall of outer ring, the second locating slot on inner ring lateral wall and determined positioned at first Neck within the groove of position, dust cap include with institute first position the flat part that is in contact of groove bottom and with dust cap skeleton outside sweep The kink that face is in contact, dust cap skeleton are engaged with kink, and flat part lateral surface is provided with dust cap fastener, dust cap Fastener outer rim is sticked into neck.

Preferably, the angular range in the infolding face of kink is 100 °~160 °.

Preferably, outer ring and inner peripheral surface scribble antirust coat.

Preferably, retainer is made up of nylon material.

Beneficial effect：

Using technical scheme provided by the utility model, compared with prior art, have the advantages that：

Install dust cap when, only the flat part of dust cap need to be fixed in the first locating slot on outer ring, then with The dust cap fastener outer rim that flat part is connected is linked in neck, you can installation fixes dust cap, therefore installs dust-proof Lid is convenient and quick, drastically increases the efficiency of installation dust cap；Dust cap and inner ring space are minimum, therefore dust-proof effect It is good；The kink infolding face of dust cap is provided with the dust cap skeleton to match with it, support of the dust cap skeleton to kink Property is good, improves the steadiness of dust cap.

Brief description of the drawings

Fig. 1 is the utility model structural profile illustration；

Fig. 2 is mplifying structure schematic diagram at A in Fig. 1；

Fig. 3 is mplifying structure schematic diagram at B in Fig. 1.

Wherein, outer ring 1, inner ring 2, retainer 3, steel ball 4, dust cap 5, flat part 51, kink 52, locating slot 6, first Locating slot 61, the second locating slot 62, neck 63, dust cap skeleton 7, dust cap fastener 8.

Embodiment

The effect of to make to architectural feature of the present utility model and being reached have it is further understand and understanding, to compared with Good embodiment and accompanying drawing coordinate detailed description, are described as follows：

As shown in Figure 1 to Figure 3, a kind of bearing with dust cap, including outer ring 1, inner ring 2, and installed in the He of outer ring 1 Retainer 3 between inner ring 2, retainer 3 are enclosed with steel ball 4, dust cap are provided between the outer ring 1 of the both sides of retainer 3 and inner ring 2 5, as improvement of the present utility model, dust cap 5 is erected in locating slot 6, and locating slot 6 is included on the madial wall of outer ring 1 First locating slot 61, the second locating slot 62 on the lateral wall of inner ring 2 and the neck 63 within the first locating slot 61, prevent Dirt lid 5 includes the flat part 51 being in contact with the bottom surface of the first locating slot 61 and is in contact with the excurvation curved surface of dust cap skeleton 7 curved Folding part 52, dust cap skeleton 7 are engaged with kink 52, and the lateral surface of flat part 51 is provided with dust cap fastener 8, dust cap card The outer rim of part 8 is sticked into neck 63.

In use, the flat part 51 of dust cap 5 need to be only fixed in the first locating slot 61 on outer ring 1, then with The outer rim of dust cap fastener 8 that flat part 52 is connected is linked in neck 63, you can installation fixes dust cap 5, dust cap 5 It is minimum with the space of inner ring 2.

Further being improved as the utility model, the angular range in the infolding face of kink 52 is 100 °~160 °, Kink in the range of this is rigidly more preferable, and dust cap intensity is more preferable.

Further improved as the utility model, outer ring 1 and the surface of inner ring 2 scribble antirust coat.Antirust coat can be with The surface oxidisation of outer ring 1 and inner ring 2 is prevented, extends the service life of outer ring 1 and inner ring 2.

Further improved as the utility model, retainer 3 is made up of nylon material.Protected made of nylon material It is with small vibration to hold frame, noise is low, and caloric value is low, and bearing capacity is high, limit speed and the life-span of bearing can be improved, to bearing lubrication Agent has compatibility.

Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations； Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of skill in the art that its according to The technical scheme described in previous embodiment can so be modified, or which part technical characteristic is replaced on an equal basis Change；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the utility model technical scheme Spirit and scope.
