Description
Technical field
The utility model relates to a kind of mechanically operated connection set, is particularly useful for the axially locating that suspension type bucket wheel speed reducer is connected with the axle spline.
Background technique
The stacker-reclaimer suspension type bucket wheel speed reducer that Changsha Heavy Machinery Plant makes with spool be connected and mainly contain dual mode, inside and outside expansion set interference connection is connected with spline.Inside and outside expansion set interference connects the requirement on machining accuracy height to matching surface, and the mounting or dismounting difficulty is big, often adopts the destroy method dismounting, and the maintenance cost height is not easy to the off-line maintenance of equipment, and magnitude of interference is not enough or the load that is hit easily causes and connects loosening skidding, and causes transmission failure.It is convenient that spline connects mounting or dismounting, and transmitting torque is big, and shortcoming is that axially locating is by partly cuing open the end face realization that the formula snap ring snaps in the male splined shaft upper groove and is fastened on female splined shaft with screw.The size of snap ring and screw is subjected to the restriction of spline shaft structure and size, and the size and the intensity of snap ring, screw are less.The centering of involute splines profile of tooth in order to satisfy assembly technology, is convenient to mounting or dismounting, and interior external spline teeth side, axle journal and speed reducer positioning hole are Spielpassung.The speed reducer center of gravity has with a certain distance from the spline attachment portion, speed reducer under action of gravity in the actual center line of external splines do not overlap, in operation process, the position of snap ring in draw-in groove is periodically to change, and during running between the key tooth mutually motion produce friction.At long-term friction and snap ring or screw easy deformation, damage and key odontotripsis under the effect of alternating stress repeatedly.In addition, it is bad partly to cut open formula snap ring sealability, and loosening, damage back foreign material are easy to enter in the spline, destroy the lubricated of spline, quicken the wearing and tearing of spline.
The model utility content
Technical problem to be solved in the utility model provides a kind of suspension type speed reducer and the axially locating connection set that the axle spline is connected, and overcomes the deficiency of suspension type speed reducer and spline Joining clasp axially locating reliability and sealability.
For solving the problems of the technologies described above, the utility model proposes following technological scheme: the axially locating connection set that a kind of suspension type speed reducer is connected with the axle spline, comprise and partly cut open the formula snap ring, it is characterized in that, at speed reducer output shaft is that the external cylindrical surface of female splined shaft is processed with one/many annular grooves, the described formula snap ring that partly cuts open is designed to special-shaped two/many bayonet arrangement, two/a plurality of bayonet sockets are stuck in respectively in the groove and described female splined shaft external cylindrical surface annular groove that bucket wheel axle is a male splined shaft simultaneously.Two/a plurality of bayonet sockets of consubstantiality and an end boss increase the described area of contact of partly cuing open formula snap ring and female splined shaft, improve the described intensity of formula snap ring and the stability that non-deformability, raising snap ring are located partly cutd open.
As further improvement, the utility model also comprises the first flange-type connecting ring, the second flange-type connecting ring, the flange connecting body that the described first flange-type connecting ring, the second flange-type connecting ring connect to form by bolt, the described formula snap ring that partly cuts open is stuck in the described flange connecting body, and closely cooperates with described flange connecting body.Connecting screw rod can add at connecting ring selects bigger nominal size increase join strength for the reinforcement join strength man-hour, and bolt connects dismounting, changes conveniently, avoids screw to connect the maintenance inconvenience that the internal thread damage causes.
The characteristics of this Placement are, two flange-type connecting rings of bolton play the fixed-site effect of partly cuing open the formula snap ring, move axially by two that partly cut open the formula snap ring/a plurality of bayonet sockets and fix, even connecting bolt occurs loosening, owing to partly cut open the formula snap ring radially not removable, two belt bayonet sockets that partly cut open the formula snap ring link together interior male splined shaft securely, strengthen the safety reliability that connects.
The utility model has improved intensity and the non-deformability of partly cuing open the formula snap ring, has improved the stability of partly cuing open formula snap ring location, and possesses good seal performance, advantage simple in structure, easy to use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a long splice composition of the present utility model.
Fig. 2 is each view of each separation assembly of comprising of the utility model.
Fig. 3 is each view that female splined shaft separates with male splined shaft.
Embodiment
It is example that this embodiment is partly cutd open the formula snap ring with special-shaped twoport, and the utility model structure is described further.
As shown in Figure 1, the first flange-type connecting ring 5 is enclosed within on the setting sleeve 3 of male splined shaft 1, one end of setting sleeve 3 closely is mounted on the bearing 2 on the male splined shaft 1, the other end partly cuts open formula snap ring 7 with special-shaped twoport and closely is connected, the second flange-type connecting ring 6 is enclosed within on the female splined shaft 8, lift then in speed reducer makes, external splines cooperates, the special-shaped twoport of packing into after lifting puts in place partly cuts open formula snap ring 7, the internal spline groove that two bayonet sockets that special-shaped twoport partly cuts open formula snap ring 7 snap in respectively, the groove of external splines, first flange-type 5, the second flange-type connecting ring, 6 usefulness bolts 4 connect, special-shaped twoport is partly cutd open formula snap ring 7 be fixed on the centre, special-shaped twoport partly cuts open the axial displacement of two interior external spliness of bayonet sockets restriction of formula snap ring 7.First flange-type 5, the second flange-type connecting ring 6 and special-shaped twoport partly cut open each surface of contact of formula snap ring 7 and leave gap about 0.2--0.5mm with the connection part of inside and outside axle, special-shaped twoport partly cuts open formula snap ring 7 and can do to regulate automatically to move with the rotation of axle between first, second flange- type connecting ring 5,6, can eliminate when running speed reducer and the bucket wheel axle center line do not overlap the loose collar and friction and the extruding between snap ring, snap ring and the draw-in groove that causes, avoid draw-in groove, snap ring damage.
As shown in Figure 2, flange- type connecting ring 5,6 and special-shaped twoport partly cut open formula snap ring 7 usefulness A3 steel or the processing of 45 steel, do not need heat treatment.
Fig. 3 left side is depicted as male splined shaft 1, and external splines groove 9 is arranged on the male splined shaft 1.The right is depicted as female splined shaft 8, annular groove 10 of external cylindrical surface processing of female splined shaft 8.Male splined shaft 1 is connected with 8 of female splined shafts and cooperates when putting in place, and two bayonet sockets that special-shaped twoport partly cuts open the formula snap ring are stuck in respectively in external splines groove 9 and the internal spline groove 10 simultaneously.
Should be noted that; the exemplary illustration that this embodiment is just done the utility model and do not limit its protection domain; those skilled in the art can also make the change of some unsubstantialities to the utility model; so long as the improvement of carrying out without creative work and to this patent, all within the protection domain of this patent.
