Description
Technical field: the utility model relates to the coupling in mechanical transmission, especially rigid coupling.
Background technique: coupling is a kind of parts very common in mechanical transmission fields, is mainly used in the connection that driving shaft and driven axle are the diaxon of same axis, and clutch is exactly modal a kind of rigid coupling.In production practices, due to equipment installation question, driving shaft and driven axle often can not coaxial lines, thereby produce many adverse effects, and the poorer equipment operation of concentricity noise, vibration are larger, and parts depreciation is faster, consumes energy more.Though also there is flexible coupling, in it, there is rubber part, in the poor occasion of concentricity, for example coupling of water conservancy pumping plant Axial-Flow pump, rubber part is worn and burns very soon, and produces pungent stink.
Model utility content: the purpose of this utility model is to provide a kind of rigid coupling that is different from clutch, can cushion the nonconcentricity of driving shaft and driven axle, realize the Flexible Transmission of rigid coupling, thereby alleviate the adverse effect that driving shaft and driven axle decentraction produce, meanwhile, when coupler component part weares and teares, can not produce stink yet.
For this reason, the technical solution the utility model proposes is, a kind of rigid coupling, mainly comprise the discoid driving wheel of the stepped shaft that has central through bore and the driven wheel that are linked into an integrated entity by the disk of two different-diameters of size, on driving wheel endoporus, there is keyway to be connected with driving shaft, on driven wheel endoporus, there is keyway to be connected with driven axle, driving wheel is a kind of drive sprocket, on the external cylindrical surface of its big diameter disc, having a circle circumferential cross-section is the leg-of-mutton drive chain gear teeth, the even number that its number of teeth is 4～100.Described driven wheel be one identical with drive sprocket by movable sprocket, on the external cylindrical surface of its big diameter disc, have the passive sprocket tooth that a circle is identical with the drive chain gear teeth.On the drive chain gear teeth, cover has an initiatively chain, on passive sprocket tooth, cover has a passive chain identical with active chain, initiatively the chain rivet of chain and passive chain is all identical with the number of teeth of the drive chain gear teeth with chain number, initiatively each root chain rivet of chain and passive chain is same chain rivet again, share chain rivet, shared chain rivet is rivet type chain rivet, its two ends all have a diameter to be greater than the rivet head in the chain rivet aperture of outer plate in sheet, shared chain axle portion between two rivet heads from left to right, cover has initiatively chain board successively, initiatively inside plank of chain, the drive chain gear teeth, initiatively inside plank of chain, initiatively chain board, passive chain board, passive inside plank of chain, passive sprocket tooth, passive inside plank of chain, passive chain board, but being enclosed within the above-mentioned each part sharing on chain rivet all can be movable relatively, share the thickness sum that chain axostylus axostyle minister degree is greater than cover above-mentioned each part thereon, again in all shared chain rivets, have at least one to be detachable chain rivet.
Therefore, the utility model and clutch have similar in form, but transmission has this qualitative difference, clutch is by the rotation that links into an integrated entity of driving wheel and driven wheel, the utility model drive sprocket and be each spinning by movable sprocket, both connect by chain, because aperture pitch between the triplet gear teeth two teeth increases with the increase in wheel footpath, the connecting bolt aperture being equivalent in clutch is variable, for the bias of driving shaft and driven axle, every shared chain rivet at drive sprocket with on by movable sprocket the residing path position of taking turns different, in transmission, showing as each root shares chain rivet and all has and radially wobble with respect to sprocket wheel separately.For intersecting of driving shaft and driven axle, drive sprocket and also crossing by movable sprocket adjacent both ends face place plane, the spacing that these two end faces share chain axle position at each root is different, in transmission, the interior outer plate that shows as every active chain and passive chain all moves axially on shared chain rivet.For being staggered of driving shaft and driven axle, above-mentioned radially wobble and move axially all exist.Therefore, the utility model has been realized the Flexible Transmission of rigid coupling, the nonconcentricity of available buffer driving shaft and driven axle, thus alleviate the adverse effect that decentraction produces.Meanwhile, there is no rubber parts in the utility model, in use, parts depreciation can not produce pungent stink yet.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
