Abstract
The utility model relates to a double-row bearing support assembly structure which comprises an end cover and a bearing spline shaft. Two ends of the bearing spline shaft press flanges and bearing end faces through hexagon slotted nuts and flat washers, the end cover and a bearing seat body are sealed through an O-shaped rubber seal ring and are pressed through a screw and a spring washer, a bearing is connected with a framework type tuber oil seal, and the end cover is provided with a grease nozzle. The double-row bearing support assembly structure has the advantages that the double-row bearing support assembly structure is novel in a seal bearing structure, reasonable and good in manufacturability and reliability, can bear large axial load and radial load at the same time, adopts a novel bearing structure mode that two ends are connected with a transmission shaft, has the cross-bridge bearing effect, and is also used for matching of multiple transmission shafts of other engineering mechanical devices.
Description
Technical field
The utility model relates to a kind of mechanical parts, particularly a kind of double row bearing support assembly structure.
Background technique
The support assembly structural design of bearing plays an important role to the kinematic accuracy of axle and the service behaviour of bearing, general bearing shaft adopts double supporting structure more, the radial position of axle is limited jointly by two supportings, each supporting place should have the centripetal or angular contact bearing of radial location effect, most bearings support assembly structure cost of production is high, complex structure, bearing load is low.
Summary of the invention
The utility model purpose provides the double row bearing support assembly structure of a kind of novel structure, good reliability.
For achieving the above object, the utility model solves the scheme that its technical problem takes and is:
This double row bearing support assembly structure, comprise end cap and supporting splined shaft, described supporting splined shaft two ends compress bead and bearing face with hexagon slotted nut by plain washer, use O type rubber seal rings for seal between described end cap and the supporting seat, and be fixed and clamped by screw and spring washer, described bearing is connected with rubber oil seal with reinforce, and described end cap is provided with grease nipple.
Preferably, described bearing is the monolateral single-row centripetal roller bearing of double inner ring.
Preferably, be fixedly connected with by cotter pin between described end cap and the supporting splined shaft.
The utility model compared with prior art has following advantages: the sealed bearing structure of this double row bearing support assembly structure is novel, rationally, manufacturability and good reliability, can bear simultaneously larger thrust load, radial load, a kind of new supporting structure form of two ends and propeller shaft couplings, play the gap bridge supporting role, it is supporting also to be used for many transmission shafts of other engineering mechanical device.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model double row bearing support assembly structure structural representation.
Among the figure: 1, bead; 2, supporting splined shaft; 3, end cap; 4, rubber oil sea; 5, bearing; 6, grease nipple; 7, supporting seat; 8, O type rubber seal; 9, screw; 10, spring washer; 11, plain washer; 12, hexagon slotted nut; 13, cotter pin.
Embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in detail:
A kind of double row bearing support assembly structure shown in Figure 1, comprise end cap 3 and supporting splined shaft 2, described supporting splined shaft 2 two ends compress bead 1 and bearing 5 end faces with hexagon slotted nut 12 by plain washer 11, seal with O type rubber seal 8 between described end cap 3 and the supporting seat 7, and be fixed and clamped by screw 9 and spring washer 10, described bearing 5 is connected with rubber oil seal with reinforce 4, and described end cap 3 is provided with grease nipple 6.
Described bearing 5 is the monolateral single-row centripetal roller bearing of double inner ring.
Be fixedly connected with by cotter pin between described end cap 3 and the supporting splined shaft 2.
The sealed bearing structure of this double row bearing support assembly structure is novel, rationally, manufacturability and good reliability, can bear simultaneously larger thrust load, radial load, a kind of new supporting structure form of two ends and propeller shaft couplings, play the gap bridge supporting role, it is supporting also to be used for many transmission shafts of other engineering mechanical device.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
