Abstract
The invention discloses a rigid coupling in the mechanical transmission field. The rigid coupling mainly comprises a driving chain wheel (7) and a driven chain wheel (5) which are provided with key grooves in shaft holes and connected with a driving shaft and a driven shaft respectively. The outer cylindrical surface of the driving chain wheel (7) and the outer cylindrical surface of the driven chain wheel (5) are provided with a circle of driving chain wheel teeth (7b) which are the same and a circle of driven chain wheel teeth (5b) which are the same respectively. The driving chain wheel teeth (7b) and the driven chain wheel teeth (5b) are sleeved with a driving chain and a driven chain respectively. The driving chain and the driven chain are provided with the same chain shafts, namely, shared chain shafts (1) which are rivet type chain shafts. All inner chain plates, outer chain plates and chain shaft rollers of the driving chain and the driven chain which are arranged on the rivet type chain shafts in a sleeved mode can move relatively. The length of the shared chain shafts (1) is larger than the sum of thicknesses of both the parts arranged on the shared chain shafts (1) in the sleeved mode. At least one shared chain shaft (1) is a detachable chain shaft. By means of the rigid coupling, the disadvantages caused when the driving shaft and the driven shaft are not concentric can be reduced, and flexible transmission of the rigid coupling can be achieved. In the use process, peculiar smell can not be produced even when the parts are abraded.
Description
Technical field: the present invention 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, the coupling of water conservancy pumping plant Axial-Flow pump for example, rubber part is worn and burns very soon, and produces pungent stink.
Summary of the invention: the object of this invention 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, when meanwhile, coupler component part weares and teares, can not produce stink yet.
For this reason, the technical solution that the present invention proposes is, a kind of rigid coupling, mainly comprise the disk discoid driving wheel of the stepped shaft that has central through bore and the driven wheel that link into an integrated entity by two different-diameters of size, on driving wheel endoporus, have keyway to be connected with driving shaft, have keyway to be connected with driven axle on driven wheel endoporus, 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, active inside plank of chain, the drive chain gear teeth, active inside plank of chain, active 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 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 present invention 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, drive sprocket of the present invention and be each spinning by movable sprocket, both connect by chain, because the increase of aperture pitch between the triplet gear teeth two teeth with wheel footpath increases, the connecting bolt aperture being equivalent in clutch is variable, bias for 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 with respect to sprocket wheel separately, has and radially wobble.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 present invention has 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 present invention, in use, parts depreciation can not produce pungent stink yet.
Below in conjunction with drawings and Examples, the invention will be further described.
Accompanying drawing explanation: Fig. 1 is the main sectional structure schematic diagram of the embodiment of the present invention 2;
Fig. 2 is the left view of Fig. 1;
