Abstract
The utility model discloses a full floating semi-axle assembly which comprises a semi-axle sleeve, a hollow connecting shaft in threaded connection to the outer end of the semi-axle sleeve, a brake hub and a semi-axle which penetrates through internal cavities of the semi-axle sleeve and the hollow connecting shaft; the brake hub is rotatably connected to the hollow connecting shaft through a big conical roller bearing near the internal end of the hollow connecting shaft and a small conical roller bearing near the external end of the hollow connecting shaft; the internal diameter of an outer ring of the big conical roller bearing is larger than the radial size of an inner ring component of the small conical roller bearing; and a flange of the semi-axle is in threaded connection with the brake hub. The full floating semi-axle assembly of the structure has low fabrication cost and is convenient to assemble and maintain.
Description
Technical field
The utility model relates to the complete floating semiaxis assembly of small-scale agricultural machinery.
Background technology
The complete floating semiaxis assembly of existing small-scale agricultural machinery, comprise axle tube, be screwed onto hollow adapter shaft, braking hub, the wheel hub of axle tube outer end and pass axle tube and the semiaxis of hollow adapter shaft inner chamber, wheel hub is rotatably connected on the hollow adapter shaft by two measure-alike ball-bearing casings, the braking hub be screwed onto on the wheel hub, semiaxis flange and wheel hub be spirally connected.The complete floating semiaxis assembly of said structure, the requirement on machining accuracy height of its braking hub, hollow adapter shaft and wheel hub, to guarantee the right alignment after the three assembles, because assembly relation complexity, even the workpiece processing precision is very high, also be difficult to guarantee after the assembling and the right alignment in the use service life and the result of use of the complete floating semiaxis assembly of influence.Because assembly relation is complicated and worker's accuracy requirement height, causes the cost of manufacture height.The use of ball-bearing casing brings the dismounting difficulty in addition, is not easy to keep in repair and be difficult to eliminate the defective of endplay.
Summary of the invention
The technical problems to be solved in the utility model is at above-mentioned defective, and a kind of assembling and complete floating semiaxis assembly easy to maintenance, that cost of manufacture is low are provided.
The above-mentioned technical matters of determining, the utility model provides a kind of complete floating semiaxis assembly with following structure, comprise axle tube, brake hub, be screwed onto the hollow adapter shaft of axle tube outer end and pass axle tube and the semiaxis of hollow adapter shaft inner chamber, its constructional feature is to brake hub by being rotatably connected on the hollow adapter shaft near the big tapered roller bearing of hollow adapter shaft the inner and the little taper roller bearing of close hollow adapter shaft outer end, and the outer ring internal diameter of big tapered roller bearing is greater than the radial dimension of the inner ring assembly of little taper roller bearing; The flange of semiaxis is spirally connected with the braking hub.
The place, the inner of described big tapered roller bearing is provided with the seal ring between hollow adapter shaft and braking hub.
Compared with prior art, the utility model has saved wheel hub, and the braking hub directly assembles with hollow adapter shaft, has simplified assembly relation, and the working accuracy of part need not very high, just can obtain better right alignment, has reduced cost of manufacture accordingly; Adopt small one and large one two tapered roller bearings to realize being rotationally connected of braking hub and hollow adapter shaft, because the outer ring and the inner ring assembly of tapered roller bearing are separable, can eliminate endplay by the relative position of adjusting inside and outside circle, the simplification of assembly relation and the employing of tapered roller bearing, make dismounting all very convenient, be convenient to assembling and maintenance.
To sum up, the utlity model has cost of manufacture low, be convenient to the advantage of assembling and keeping in repair.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, complete floating semiaxis assembly, comprise axle tube 1, be screwed onto hollow adapter shaft 2, the braking hub 3 of axle tube 1 outer end and pass axle tube 1 and the semiaxis 4 of hollow adapter shaft 2 inner chambers, braking hub 3 is by being rotatably connected on the hollow adapter shaft 2 near the big tapered roller bearing 5 of hollow adapter shaft 2 the inners and the conelet coro bearng 6 of close hollow adapter shaft 2 outer ends, the outer ring internal diameter of big tapered roller bearing 5 is greater than the radial dimension of the inner ring assembly of conelet coro bearng 6, and inner ring assembly comprises inner ring, retainer and roller; The flange 8 of semiaxis 4 is spirally connected with braking hub 3.The place, the inner of big tapered roller bearing 5 is provided with the seal ring 7 between hollow adapter shaft 2 and braking hub 3.
