Description

The leakproof structure-improved of rolling wheel

Technical field

The utility model particularly relates to a kind of leakproof of rolling wheel about a kind of rolling wheel structure applied to body maker operation Structure-improved.

Background technique

Tank body, need to can be with cover riveted by anti-side when molding.However the volume currently used for the anti-side operation of body maker Wheel construction, wheel shaft are not provided with oil filler point, therefore butter need to be smeared when combination in rolling wheel, it is ensured that wheel shaft rotates smooth Degree, if but when need to be supplemented butter, it needs all to disassemble the rolling wheel, extremely trouble and time-consuming, working efficiency is greatly reduced, and Leak-proof effect is not good for the rolling wheel, and when the rolling wheel being caused to rotate actuation, lubrication butter, which are easy to overflow from wheel shaft, to be lost, and not only results in The number that pollution when tank body manufactures, even more increase butter are filled up, lacks practicability.

Utility model content

Utility model aims to solve drawbacks described above of the existing technology, and providing one kind prevents lubrication butter from overflowing It is lost and then is promoted out the leakproof structure-improved of the rolling wheel of tank operating efficiency processed.

The leakproof structure-improved of the rolling wheel of the utility model, including a wheel shaft, a upper cover, a leak-proof gasket and a foreign steamer Seat, the wheel shaft have one group and connect section and a combined segment, which, which connects, forms a limit stopper between section and the combined segment, on this Sequentially group is placed on the combined segment of the wheel shaft for lid, the leak-proof gasket and the outer wheel seat, and outside the outer wheel seat internal diameter and combined segment An at least bearing is also cased between diameter, finally by the end collocation one bottom cover closing limitation of the outer wheel seat, it is characterised in that: the leakproof Washer includes a plastics outer ring, a metallic inner and an elastic beam ring, which forms one and wear hole, then by This, which wears hole and up extends, sets a ring wall, the ring wall internal diameter be it is concavo-convex be equipped with an engaging recessed part and fasten protrusion, and the ring Wall outer diameter is then equipped with an annular groove, which wears hole and its ring wall internal diameter greater than the plastics outer ring, and by squeezing Pressure mode is inserted in the ring wall, and finally the elastic bunch ring set is set in the annular groove of the ring wall outer diameter again, enables the ring wall internal diameter energy The outer diameter of metallic inner is tightened and adhere well to, and then achievees the purpose that closed, leakproof.

Preferably, the wheel shaft axially wears an axis hole by combined segment end, and section connect by the group sets one and enter oilhole and the axis Hole communicates.

Preferably, the group, which connects section, also sets a circular groove, and by the circular groove sets one and enter oilhole and communicated with the axis hole.

Preferably, the axis hole front end of the wheel shaft forms an inner cone recess, it is also equipped with thread segment inside, for one vittate One baffle is screw-locked at the wheel shaft front end and forms positioning by screw, while limiting the bearing using the baffle.

Preferably, the inner cone recess internal diameter also sets a limit recess portion, and the baffle is then correspondingly provided with stopper protrusion and the limit Position recess portion engaging positioning.

Preferably, the outer wheel seat is equipped with an accommodating space to be hollow, the upper half ring of the accommodating space sets a defining flange, Lower end is then equipped with an internal thread segment.

Preferably, the plastics outer ring periphery is also equidirectional equipped with external annulus with the ring wall, and in the ring wall and the outer ring An annular ditch groove is formed between wall.

Preferably, the metallic inner internal diameter sets an annular recess, cooperation one o-ring of insertion.

The utility model has the following beneficial effects: rolling wheel is injected butter in axis hole by the oilhole that enters of wheel shaft group connecting part, And reach the lubrication of bearing along the export of the oil duct of axis hole and screw, and the outer wheel seat passes through upper cover in the other end of accommodating space And leak-proof gasket and the wheel shaft form leak-stopping air-tight state, and the leak-proof gasket be even more via plastics outer ring, metallic inner with And the assembling cooperation of elastic beam ring, certain block butter overflow the case where being lost from upper cover or along wheel shaft, tank processed are avoided to make There are butter to overflow in industry and lead to the pollution of tank body, also ensures that butter can be limited to the lubrication that accommodating space reaches bearing with the time The operating efficiency of tank processed is substantially improved in effect.
