Description
Technical field
This novel practical relates to a kind of chain for high dust atmosphere.
Background technique
The matching used Conveying chains of bucket continuous ship unloader uses in the environment of high dust, therefore higher to the seal request of this kind of chain, otherwise cannot meet requirement in working life.Bucket continuous ship unloader is widely used at harbour, all the Conveying chains that adopts tratitional technology to manufacture mostly, the sealing means in guide gap is all generally to adopt the form that increases seal ring between interior outer plate to reach sealing effect, the sealing effect of this mode is undesirable, when use, noise is large, and working life is short.And external to this chain running in high dust atmosphere, the sealing means in guide gap generally adopts inner plate to dig groove, outer plate is made boss, and mode intermeshing by both and increase copper backing in outside reaches the object of sealing, and effect is undesirable.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of simple in structure, good sealing effect, the little chain for high dust atmosphere of operation noise.
In order to realize above-mentioned object, the utility model has adopted following technological scheme:
A kind of chain for high dust atmosphere, comprise multiple chain links, between adjacent link, pass through bearing pin, outer plate connects, described chain link comprises inner plate, sleeve and roller, jacket casing is located at the outside of bearing pin, sleeve outside suit roller, two inner plates are set in sleeve two ends, bearing pin two ends are connected with outer plate, on the madial wall of the outer plate of the both sides of described bearing pin, be interval with first ring connected in star and the second annular groove, on the outer side wall of described inner plate, the position corresponding with first ring connected in star and the second annular groove is provided with the 3rd annular groove and Fourth Ring connected in star, in described first ring connected in star and the 3rd annular groove, be embedded with dust ring A, in described the second annular groove and Fourth Ring connected in star, be embedded with dust ring B, the outside of described dust ring B is provided with O RunddichtringO, the outside of O RunddichtringO is provided with dust ring C.
As preferred version: one end of described bearing pin is provided with priming cup, and this priming cup is communicated with the axial blind hole being located on bearing pin, this axial blind hole is communicated with the oil storage tank between sleeve and bearing pin by several radial holes A.
As preferred version: between described dust ring A and dust ring B, be filled with composite calcium-base fat, further strengthen the sealability of chain.
As preferred version: described outer plate comprises circular hole outer plate and different hole outer plate, and described bearing pin comprises have strong market potential axle and short pin shaft.
The utility model is owing to having adopted above-mentioned technological scheme, by offer groove on outer plate and inner plate, and in groove, be provided with dust ring, adopt again the mode of seal ring and general dust ring to seal in groove dust ring outside, noise while having reduced operation, improved sealing effect, the utility model sealing configuration is easy, processing cost is low, long service life.
