Abstract
The utility model relates to a large crane wheel driving mechanism, comprising a motor, an arrester connected with the motor, a reducer connected with the arrester, and a shaft coupling connected with the reducer through a shaft adapter. The shaft coupling is connected with one end of a transmission shaft and the other end of the transmission shaft is connected with the wheel through the shaft coupling and the shaft adapter. The large crane wheel driving mechanism is characterized in that the shaft coupling is a universal shaft coupling; an outer spigot is arranged on the head face of a connecting tray of the shaft coupling; an inner spigot matching with the outer spigot of the connecting tray of the shaft coupling is arranged on the head face of an end cap of the shaft adapter; and the transmission shaft connected with the shaft coupling is a telescopic transmission shaft. With above structure, the universal shaft coupling is connected with the telescopic transmission shaft, thus enlarging application range. Meanwhile, adopting spigots to position, the large crane wheel driving mechanism is accurate to position, reduces machining difficulties and lowers machining cost. In addition, the large crane wheel driving mechanism also has the advantages of simple structure, low noise and long service life.
Description
Technical field
The utility model belongs to goliath and makes the field, particularly relates to a kind of goliath wheel drive mechanism.
Background technology
Goliath is widely used in industries such as electric power, the energy, space flight, mould, building materials at present.Mainly cooperate long straight shaft to realize by gear coupling in existing goliath wheel drive, the terminal pad of coupler is located by locating piece with the hand that is coupling and is guaranteed setting accuracy.Use gear coupling manufacturing cost height, the maintenance inconvenience is installed; Employing locating piece location, two location that require to cooperate must guarantee with one heart, improve difficulty of processing and tooling cost, if two locating piece out of reach quality of fits, so when operation between big, the part of noise wearing and tearing bigger, cause union piece short service life.Said structure is applicable to wheel and walks on stage and is positioned at same plane in addition, and Applicable scope is narrower.
Summary of the invention
The utility model for solve the technical matters that exists in the known technology provide a kind of simple in structure, noise is little, long service life and goliath wheel drive mechanism applied widely.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of goliath wheel drive mechanism, comprise: motor, the drg that links to each other with motor, the retarder, the retarder that link to each other with drg are connected transmission shaft one end by the hand bonded assembly coupler that is coupling, coupler, the transmission shaft other end is connected wheel by coupler with the hand that is coupling, it is characterized in that: described coupler adopts universal coupling, be shaped on outer stopper on the terminal pad end face of coupler, being coupling is shaped on the inner stopper that cooperates with coupler terminal pad outer stopper on the end cap end face of hand, describedly adopts the telescoping transmission shaft with coupler bonded assembly transmission shaft.
Advantage and the good effect that the utlity model has are: owing to adopt universal coupling to cooperate with unequallength drivershaft, applicable to wheel with walk on stage into certain drift angle, also can guarantee its transmission effect, so enlarge its range of use; The universal coupling terminal pad is located by seam with the hand that is coupling, and accurate positioning has guaranteed assembly precision, and reduces difficulty of processing, has reduced tooling cost; Therefore said structure is simple, noise is little and long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an I portion enlarged drawing among Fig. 1;
Fig. 3 is another running condition structural representation.
Among the figure: 1, motor; 2, drg; 3, retarder; 4, universal coupling; 4-1, terminal pad; 4-2, outer stopper; 5, transmission shaft; 6, the hand that is coupling; 6-1, end cap; 6-2, inner stopper; 7, the hand that is coupling; 8, wheel; 9, bolt.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, motor 1 connects drg 2 output torque is passed to drg, drg 2 bonded assembly retarders 3, and retarder 3 is by the hand 6 bonded assembly universal couplings 4 that are coupling, universal coupling 4 connects an end of transmission shaft 5, and this transmission shaft adopts the telescoping transmission shaft.Transmission shaft 5 other ends are connected wheel 8 by universal coupling 4 with the hand 7 that is coupling.Be shaped on outer stopper 4-2 on the terminal pad 4-1 end face of wherein said universal coupling 4, be coupling and be shaped on the inner stopper 6-2 that cooperates with the outer stopper 4-2 of the terminal pad 4-1 of universal coupling 4 on the end cap 6-1 end face of hand (6,7), universal coupling 4 is located by seam with the hand (6,7) that is coupling, and closes connection by 9 on bolt.
The utility model also is applicable to when wheel axis becomes certain drift angle with the retarder axis, still can satisfy operating needs, sees also Fig. 3.
