Abstract
The invention relates to a double-row bearing support assembly structure which comprises an end cap and a support spline shaft. Two ends of the support spline shaft compress a flange and the end face of a bearing by using hexagon slotted nuts through a flat washer, the end cap and a support seat are sealed through an O-shaped rubber sealing ring and are fixed and compressed through screws and a spring washer, the bearing is connected with a frame type rubber grease seal, and the end cap is provided with a grease nipple. The double-row bearing support assembly structure has the advantages that the double-row bearing support assembly structure is novel and reasonable in bearing sealing structure, fine in manufacturability and reliability and capable of simultaneously bearing large axial load and radial load, is a novel support structure with two ends connected with a transmission shaft, has a bridge bearing function and is also applied to other engineering machinery equipment for multiple transmission shaft matching.
Description
Technical field
The present invention 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 object of the invention provides the double row bearing support assembly structure of a kind of novel structure, good reliability.
For achieving the above object, the present invention 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 present invention 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:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is double row bearing support assembly structure structural representation of the present invention.
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
Describe the present invention below in conjunction with the drawings and the specific embodiments:
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 invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
