Abstract
The utility model discloses a clamping ring bearing type flange-face coupling which includes two fixedly connected half-couplings respectively provided with flanges and flutes in mutual fit. Key slots in fit connection with transmission shaft keys are arranged on the half-couplings. The utility model is characterized in that half clamping rings are respectively arranged in the half-couplings, and annular slots in fit with the half clamping rings are arranged at the shaft ends of the connected transmission shafts. The utility model has the advantages of convenient installation as the traditional rigidity flange-face coupling, and large axial bearing capacity and reliable loose prevention as the clamping type coupling.
Description
Technical field
The utility model relates to a kind of mechanical transmission component, and specifically a kind of coupling is meant snap ring bearing type flange coupling especially.
Background technique
Coupling is that two axles (driving shaft and driven shaft) that are used for connecting in the different institutions make it the mechanical parts of common rotation with transmitting torque, and what more generally use in vertical stirring system is rigid flanges coupling and folder shell-type coupling.Traditional rigid flanges coupling is that two half-couplinves are connected with diaxon respectively with parallel key, with bolt two half-couplinves are fused then, the axial restraint that is connected transmission shaft relies on the axle head clamping bolt to realize, as shown in Figure 1, its up and down half-coupling each need a clamping bolt 1 and backing plate 2 to realize axial restraint with transmission shaft, not only structurally the extended axial length of shaft coupling, and there is the hidden danger that gets loose in clamping bolt.Clamping coupling is used and is divided half snap ring, 7 structures to solve axial locking orientation problem well, as shown in Figure 2, and axial bearing capacity also improves greatly, but there is the shortcoming that inconvenience is installed in actual applications, particularly under the situation that shaft assembly weight is very big down, folder shell-type coupling can't provide puts the axial region position, brings very big difficulty for the centering location of last lower shaft.
The model utility content
The purpose of this utility model is the shortcoming and defect that exists in the prior art in order to overcome, and a kind of snap ring bearing type flange coupling is provided.
For achieving the above object, the technical solution of the utility model is, include and be respectively equipped with the flange that cooperatively interacts and two half-couplinves of fixedlying connected of groove, described half-coupling is provided with the keyway that is connected with the transmission axle key, it is characterized in that: respectively be provided with branch half snap ring in the described half-coupling, connected transmission shaft end is provided with this and divides half snap ring adaptive circular groove.
Further being provided with is to be provided with in the described half-coupling and the axial restraint step surface that divides half snap ring external diameter to match.
Further be provided with is that described half joining shaft is provided with the fastening screw trip bolt with transmission shaft sidewall secure fit.
Advantage of the present utility model is: the utility model divides half snap ring to come the axial restraint transmission shaft by adopting on the basis of flange coupling, given full play to the advantage of the axial load-bearing that divides half snap ring, eliminated the insecure hidden danger of the axial load-bearing of flange coupling, because being semiaxis, independently installs respectively by coupling, therefore provide and put the axial region position reliably, in the application of vertical heavy major axis, demonstrated special advantages.The utility model not only has the advantage that the conventional rigid flange coupling is convenient to install, and it is big to possess folder shell-type coupling axial bearing capacity, locking reliable advantage.

Embodiment
Embodiment of the present utility model as shown in Figure 3, include and be respectively equipped with the flange 31 that cooperatively interacts and two half-couplinves that are mutually permanently connected 3 of groove 32, described two half-couplinves 3 of present embodiment adopt bolt 4 to be fixedly connected, described half-coupling 3 is provided with the keyway 33 that cooperates connection with transmission shaft 5 keys, half-coupling 3 is installed in respectively on the transmission shaft 5 (driving shaft and driven shaft) by parallel key 6, be provided with branch half snap ring 7 in the described half-coupling 3, connected transmission shaft 5 axle heads are provided with this and divide half snap ring internal diameter and the matched circular groove 51 of width, preferably be provided with in the described half-coupling 3 of present embodiment and divide the half snap ring axial restraint step surface 34 that 7 external diameters match, convenient installing and locating of dividing half snap ring.During installation, must earlier half-coupling be contained on the transmission shaft, and the axle head circular groove that makes transmission shaft exposes half-coupling flange (or groove) plane, to divide half snap ring to be inserted in the transmission shaft end circular groove, return the axial restraint step surface that half-coupling is provided with and contact in dividing half snap ring and half-coupling, at last two half-couplinves are connected with bolt.Therefore novel the employing on the basis of flange coupling of this enforcement divides half snap ring to come the axial restraint transmission shaft, given full play to the advantage of the axial load-bearing that divides half snap ring, eliminated the insecure hidden danger of the axial load-bearing of flange coupling, because being semiaxis, independently installs respectively by coupling, therefore provide and put the axial region position reliably, in the application of vertical heavy major axis, demonstrated special advantages.The utility model not only has the advantage of the installation that the conventional rigid flange coupling is convenient to, and it is big to possess folder shell-type coupling axial bearing capacity, locking reliable advantage.The described half-coupling 3 of present embodiment is provided with the fastening screw trip bolt 8 with transmission shaft sidewall secure fit in addition, plays axially auxiliary fixation.
