Abstract
The utility model relates to a kind of dust-proof roller bearing for gearbox, comprise bearing body, described bearing body comprises bearing outer ring, bearing inner race, cylindrical roller, retainer and stop ring, described bearing body is fixed with dust cover near the outside of gearbox, and described dust cover offers oil outlet.This dust-proof roller bearing being used for gearbox has dust cover in the arranged outside near gearbox, can enter in bearing by preventing pollution thing, dust cover offers oil outlet, the high temperature that can prevent transmission internal from producing causes the dilatancy of dust cover, pops or early failue, thus improves working life.
Description
Technical field
The utility model relates to field of bearings, particularly relates to a kind of dust-proof roller bearing for gearbox.
Background technique
Gearbox roller bearing, in running, can enter the foreign matter in running environment by casing outer side surface, the metal particle etc. produced as part engagement can produce impression on the roller surface of bearing, causes fatigue equivalent and peels off.Roller bearing at present on gearbox, scarcely adopts dustproof cover structure by casing outer side surface, can directly cause entering of from external contaminants; With the roller bearing of dustproof cover structure, oilhole do not outputed by dust cover, the high temperature that such transmission internal produces can cause the dilatancy of dust cover, pop or early failue.
Model utility content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, provides that a kind of structure is simple, easy to assembly, the dust-proof roller bearing for gearbox of long service life.
The utility model solves the technological scheme that its technical problem adopts: a kind of dust-proof roller bearing for gearbox, comprise bearing body, described bearing body comprises bearing outer ring, bearing inner race, cylindrical roller, retainer and stop ring, described bearing body is fixed with dust cover near the outside of gearbox, and described dust cover offers oil outlet.
In the utility model one preferred embodiment, described oil outlet is two, and two oil outlets are symmetrical arranged.
In the utility model one preferred embodiment, described dust cover outer rim is provided with flange, and dust cover inner edge is provided with sealing rubber ring, and described oil outlet is arranged between flange and sealing rubber ring, described bearing outer ring offers can with the draw-in groove of flange clamping.
The beneficial effects of the utility model are: this dust-proof roller bearing being used for gearbox has dust cover in the arranged outside near gearbox, can enter in bearing by preventing pollution thing, dust cover offers oil outlet, the high temperature that can prevent transmission internal from producing causes the dilatancy of dust cover, pops or early failue, thus improves working life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the dust-proof roller bearing for gearbox of the present utility model;
Fig. 2 is the structural representation of the dust cover of the dust-proof roller bearing for gearbox of the present utility model.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1 and Figure 2, a kind of dust-proof roller bearing for gearbox, comprise bearing body, described bearing body comprises bearing outer ring 1, bearing inner race 2, cylindrical roller 4, retainer 3 and stop ring 5, described bearing body is fixed with dust cover 6 near the outside of gearbox, and described dust cover 6 offers oil outlet 61.
As preferably, described oil outlet 61 is two, and two oil outlets 61 are symmetrical arranged.
Described dust cover outer rim is provided with flange 62, and dust cover inner edge is provided with sealing rubber ring 63, and described oil outlet 61 is arranged between flange 62 and sealing rubber ring 63, described bearing outer ring 1 offers can with the draw-in groove of flange 62 clamping.Dust cover 6 is fixed on bearing by flange 62, and sealing rubber ring 63 contacts with bearing inner race 2 raceway face, easy installation and removal.
Compared with prior art, this dust-proof roller bearing being used for gearbox has dust cover 6 in the arranged outside near gearbox, can enter in bearing by preventing pollution thing, dust cover 6 offers oil outlet 61, the high temperature that can prevent transmission internal from producing causes the dilatancy of dust cover 6, pops or early failue, thus improves working life.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
