Abstract

The utility model discloses a sealing device on a speed reducer, which comprises a flange body, a rubber sealing ring, a screw cover and a fixed bolt, wherein the end face on the rubber sealing ring in contact with the screw cover is provided with an annualar wedge groove with wedge-shaped section, a circular compression ring is arranged between the wedge groove and the screw cover, and the width of the section of the circular compression ring is slightly larger than that of the opening of the wedge groove. The direct contact section of the flange body and a rotating shaft is also provided with a labyrinth type sealing device which comprises one or more annular grooves and a reflow hole at the bottom of the flange body, and the sealing device can also be made into an open structure. The utility model has the advantages that: the sealing device can realize the continuous compensation of the abrasion by depending on the per se structure, ensures the sealing reliability, and enables the sealing ring to be fully utilized. More particularly, the sealing device can completely avoid stop loss caused only by replacement of sealing members, and therefore, produced economic benefit is remarkable. The sealing device can be used for speed reduction in various fields.

Description

Seal arrangement on the speed reducer
Technical field
The utility model relates to the seal arrangement on a kind of speed reducer.
Background technique
Because the long-time uninterrupted rotation of speed reducer output, input shaft, will inevitably cause the friction loss of Sealing, if can not be compensated to continuous and effective for this loss, will form seepage because of the excesssive gap of Sealing, the lighter can cause the loss and the environmental pollution of lubricant oil, heavy then wearing and tearing that also can accelerating gear, or even damage.The most popular method that addresses the above problem at present can only be in time to change sealing gasket, and the difficulty that this mode is implemented for the pumping unit speed reducer that use in the oil field is very big.Because continuity and the work under bad environment of this equipment in the operation running, the frequency that this Sealing is changed is high especially, and not only the disassemble and assemble work amount is very big, but also can not finish at the scene, and is therefore very big for normal oil producing operation influence.This for many years situation is a great problem that restriction is recovered the oil and produced always.
Summary of the invention
Goal of the invention of the present utility model is to provide the seal arrangement on a kind of speed reducer, the sealing device can continuous effective the wearing and tearing of ground compensation sealing part, thereby prolong working life of Sealing.
The technological scheme that the utility model proposes is: the sealing device comprises flange body, be contained in the rubber seal in the flange body, with the gland and a plurality of fixing bolt that are pressed on the rubber seal, it is the vee-cut of wedge-like that the end face that contacts with gland on rubber seal has a ring-type, section, between this vee-cut and gland, be provided with round pressure ring, the lateral section that the circle pressure ring contacts with vee-cut is arc or triangle, and the width of this section is slightly larger than the A/F of vee-cut.The opposite side end face of rubber seal is a planar annular, on flange body, be provided with the identical seal ring mounting groove with the rubber seal external shape of indent, the planar annular end of the rubber seal seal ring mounting groove of packing into, the circle pressure ring is pressed in the vee-cut, gland is pressed on the round pressure ring, is fixed by fixing bolt.
Also be provided with labyrinth-type excluder at described flange body and the direct contact-segment of running shaft, constitute by one or more annular groove and return port in the flange body bottom.
Above-mentioned seal arrangement can also be made open architecture, promptly is provided with place's inclined section opening on the sidewall of described round pressure ring and rubber seal.
The beneficial effects of the utility model are: the sealing device can be realized the lasting compensation of wearing and tearing by self structure, guarantees the reliability of sealing, and seal ring is utilized to the fullest.Test confirms can prolong more than five times than existing product its working life.Not only can reduce the buying expenses of spare part significantly, and reduce working strength of workers widely.More outstanding is [to avoid fully merely because of changing the shutdown loss that Sealing causes, because of the economic benefit that produces a bit is conspicuous.This seal arrangement can use in the deceleration in the various fields.
