Abstract
The utility model relates to an improved roller sealing device for a belt conveyer, belonging to the technical field of mine machinery, and solving waterproof, dustproof and resistance problems. The utility model has the technical proposal that a curved surface-shaped sealing cover 8 whose outer edge is provided with a semi-ring surface forming clearance fit with the ring surface-shaped bulged end surface of a roller bearing base 11 is installed between an outer retainer ring 9 and a shaft clamp 10. The utility model can prevent dust and eater from entering and solves the existing problem under the condition of not increasing rotating resistance, and the utility model can be widely used for renovating and reforming a roller of the belt conveyer.
Description
The utility model discloses a kind of non-contacting seal device of improved sealing-tape machine carrying roller, belong to the mining machinery technical field.
Adhesive tape conveyor is the Transport Machinery that factories and miness, harbour generally use, and carrying roller is the critical component of sealing-tape machine, and its dustproof and waterproof and rotational resistance are three important technology indexs indicating capability and performance.Mutual restriction between dustproof and waterproof and the rotational resistance can not be taken into account in three indexs, is a difficult problem that perplexs technical personnel for a long time.Therefore, provide a kind of sealing arrangement of carrying roller both to solve the water proof and dust proof problem, not increasing its rotational resistance again is crucial technical task.
Invention task of the present utility model provides a kind of sealing-tape machine carrying roller sealing arrangement dustproof, that water resistance has satisfactory rotational resistance again that satisfies.
Technical essential of the present utility model shows as the flat circle ring-type baffle plate that carrying roller is original and makes the outer seal cover cap that is together the planar curve form of semi-ring of free-running fit with the planar outstanding end face of Idler bearing seat ring is arranged.In order to entering of anti-sealing and dust, thoroughly having solved carrying roller water proof and dust proof and rotational resistance index can not technical barrier simultaneously up to standard.
The utility model is finished like this: a kind of contactless sealing-tape machine carrying roller sealing arrangement, comprise and embed the seal ring 3 that is welded on bearing seat 11 neck bearings 4 inboards of one with roll body 1, the labyrinth seal circle assembly that the inner seal ring 5 in bearing 4 outsides and exterior seal ring 6 are formed, and inner shield ring 7, outer back-up ring 9, be stuck in the anchor shaft card 10 of axle on 2 and constitute, it is characterized in that having installed between the back-up ring 9 and axle card 10 outside an outer has together and gives prominence to the seal cover cap 8 that end face is the planar curve form of semi-ring of free-running fit with roller carrier shaft bearing 11 anchor ring shapes.
Because between seal cover cap 8 and bearing seat 11 end faces gap is arranged, the surface tension of water can stop water to enter in the sealing arrangement when water enters the gap, when carrying roller rotated, the centnifugal force of generation can drive water and splash laterally.Simultaneously dust is rinsed well together.Thereby under the situation that does not increase rotational resistance, solved the problem of water proof and dust proof.This device is applicable to that the carrying roller of various sealing-tape machines uses.Because water proof and dust proof, resistance is little, can reduce maintenance, improves service life, and is energy-saving and cost-reducing, has tangible economic benefit.
Figure of description 1 is a structural section of the present utility model, among the figure:
1, roll body, 2, axle, 3, seal ring, 4, bearing, 5, inner seal ring, 6, exterior seal ring, 7, inner shield ring, 8, seal cover cap, 9, outer back-up ring, 10, the axle card, 11, bearing seat.
Embodiment seal cover cap 10 of the present utility model adopts the steel plate punching press to make the plating anti-rust treatment.
Claims (1)
1, a kind of contactless sealing-tape machine carrying roller sealing arrangement, comprise and embed the inboard seal ring (3) of bearing seat (11) neck bearing (4) that is welded on one with roll body (1), the labyrinth seal circle assembly that the inner seal ring (5) in bearing (4) outside and exterior seal ring (6) are formed, and inner shield ring (7), outer back-up ring (9), be stuck in the anchor shaft card (10) of axle on (2) and constitute, it is characterized in that outside that back-up ring (9) and axle block an outer has been installed between (10) has and give prominence to the seal cover cap (8) that end face is the planar curve form of semi-ring of free-running fit with roller carrier shaft bearing (11) anchor ring shape one.
