The expansion-type pin coupling with elastic sleeves is characterized by also comprising two sleeve expanding components, wherein the end faces of the driving half coupling and the driven half coupling are respectively provided with expansion sleeve installation counter bores; the sleeve expanding components are arranged in the expansion sleeve installation counter bores to realize non-key joint of a shaft and the half couplings when the shaft extension ends of a driving transmission shaft and a driven transmission shaft are non-key optical shafts, thus providing a safe and reliable connection way for the shafts connected by the non-key optical shafts, and meeting the safe moment transfer between the shaft extension ends of the optical shaft; the expansion-type pin coupling is simple in structure and convenient to produce and manufacture, can effectively reduce the weights of a coupling and a transfer shaft and reduce the installation space; after installation, the coupling and the shaft are high in coaxiality, convenient to install and maintain, reasonable in cost and the like.
Description
Technical field
The utility model relates to a kind of coupling, and definite saying is a kind of for the keyless expansion-fastening type rubbercushioned sleeve bearing coupling of optical axis.
Background technique
Traditional coupling is usually more adopts singly-bounds, build more, connect between spline or profile and the transmission shaft, realization moment is transmitted, just must there be like this keyway or profile to exist on the transmission shaft shaft extension, affect coupling and the coaxial accuracy requirement of rear and axle is installed or shaft extension is had certain damage.And for the transmission shaft shaft extension for being the moment transmission of optical axis without keyway or profile, traditional coupling just can't use, its use narrow limitation has just displayed.Be head it off, it is just necessary to manufacture and design the expansion-fastening type rubbercushioned sleeve bearing coupling.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, be convenient to manufacture, install after coupling, installation and maintenance high with the axle coaxality conveniently, the rational expansion-fastening type rubbercushioned sleeve bearing coupling of cost; This coupling can satisfy moment safe transfer between the optical axis shaft extension, realizes that optical axis is keyless.
For realizing above-mentioned purpose, technical solution adopted in the utility model is as follows: a kind of expansion-fastening type rubbercushioned sleeve bearing coupling comprises initiatively half-coupling, driven half-coupling, is used for connecting the initiatively taper pin assembly of half-coupling and driven half-coupling; It is characterized in that: it also comprises two expansion set assemblies, and initiatively the end face of half-coupling and driven half-coupling is respectively equipped with expansion sleeve counterbore is installed, and the expansion set assembly is installed on expansion sleeve counterbore is installed.
The utility model overlaps the pin coupling with prior elastic structurally to be improved, making it has enough installing spaces that cooperates with expansion set, take full advantage of the resiliently deformable of expansion set material and form the gapless interference fit with half-coupling and transmission shaft thus, connect for providing safe and reliable between transmission shaft and coupling.
When this expansion-fastening type rubbercushioned sleeve bearing coupling is used for main drive shaft and is without the key optical axis from transmission shaft shaft extension end, between axle and half-coupling, realize keyless, for axle head is to be connected diaxon without the key optical axis to provide a kind of safe and reliable Placement, satisfy moment safe transfer between the optical axis shaft extension.The characteristics such as it is simple to the utlity model has coupler structure, is convenient to manufacture, and can effectively reduce the weight of coupling and passing shaft, reduces installing space, and coupling and axle coaxality are high after installing, and installation and maintenance are convenient, and cost is reasonable.
Shaft extension end for long adopts spacing annulus to play position-limiting action, with the weight of a whole set of expansion-fastening type rubbercushioned sleeve bearing coupling of effective reduction system.

Embodiment
As shown in Figure 1: a kind of expansion-fastening type rubbercushioned sleeve bearing coupling comprises active half-coupling 9, the driven half-coupling 1 that is connected, the taper pin assembly that is used for connecting active half-coupling 9 and driven half-coupling 1; The taper pin assembly is comprised of taper pin 4, rubber elasticity cover 5, back-up ring 6, spring washer 7 and nut 8; Also comprise two expansion set assemblies 3, referring to Fig. 4 and Fig. 5, initiatively half-coupling 9 is respectively equipped with expansion sleeve installation counterbore 10 with the end face of driven half-coupling 1, and expansion set assembly 3 is installed on expansion sleeve counterbore 10 is installed.
Referring to Fig. 2 and Fig. 3: expansion set assembly 3 is the standard piece that are purchased, and comprises expansion set body 35, interior elastic sleeve 31, tapered collar 32, outer elastic sleeve 33 and bolt 34; Elastic sleeve 31 in the expansion set body 35 inner circles dress, the outer elastic sleeve 33 of expansion set body 35 cylindricals dress, expansion set body 35 end faces are evenly laid mounting hole, symmetrical tapered collar 32, the tapered collar 32 interior construction bolts 34 installed in the mounting hole.
As of the present utility model perfect; for long shaft extension end; weight for a whole set of expansion-fastening type rubbercushioned sleeve bearing coupling of effective reduction system; referring to Fig. 1: initiatively half-coupling 9 all is equipped with spacing annulus 2 with driven half-coupling 1 outer end; play on the one hand the axial limiting effect; annulus 2 can effectively reduce relatively rotating of annulus and between centers with driving shaft 11 and driven shaft 12 little Spielpassung radially on the other hand, plays the protective action to shaft extension.
After the expansion-fastening type rubbercushioned sleeve bearing coupling was installed to the driving shaft and driven shaft that is connected, driving shaft 11 and 9 of active half-couplings passed through expansion set assembly 3 and form interference fit, and 1 of driven shaft 12 and driven half-coupling pass through expansion set assembly 3 and form interference fit.
Mounting type of the present utility model is: first at driving shaft 11 cover upper limit annulus 2, initiatively half-coupling 9 is loaded on the driving shaft 11 again, follow at driving shaft 11 and the expansion set assembly 3 of initiatively packing between the coupling 9, and symmetry alternately tights a bolt 34 by required moment, under the effect of tapered collar 32, the endoporus of interior elastic sleeve 31 is dwindled, the external diameter of outer elastic sleeve 33 swells, driving shaft 11 and initiatively 9 of half-couplings form interference fit by expansion set assembly 3.
Identical on the assemble sequence that driven half-coupling 1, spacing annulus 2 and expansion set assembly 3 be installed on the driven shaft 12 and the driving shaft.Half-coupling on the diaxon and expansion set assembled well after, with the table meet the requirements take two half-couplings as the benchmark centering respectively after, rubber elasticity cover 5, back-up ring 6 are contained on the taper pin 4 successively, the initiatively half-coupling 1 of packing into, to initiatively half-coupling 1 and driven half-coupling 9 integrators with spring washer 7 and nut 8, so far, assembly process of the present utility model is finished.Bolt 34 also is the parts that prevent that expansion set assembly 3 from becoming flexible.
