Abstract
The utility model relates to an improved structure for a crane travel mechanism of a small-tonnage bridge crane. The improved structure comprises a motor, a brake, a reductor, crane wheel axles and crane wheels, and is characterized in that a coupler for connecting the reductor with the crane wheel axles is a universal coupler; one end of the universal coupler is connected with the output shaft of the reductor; and the other end of the universal coupler is connected to the crane wheel axles. Compared with a gear coupler, the universal coupler has the advantages of simple structure, convenience in maintenance, and high exchangeability; moreover, through the adoption of the universal coupler, the abnormal phenomenon of the gear mesh of the reductor caused by deviation and the like is reduced; and the universal coupler can eliminate undesirable auxiliary load, and provide sufficient compensation when the output shaft of the reductor are not concentric to the crane wheel axles. Therefore, the service life of the reductor is improved. The requirements of height difference and level difference of the universal coupler are relatively low.
Description
Technical field
The utility model belongs to crane in bridge type manufacturing technology field, particularly relates to a kind of improvement structure of little tonnage bridge crane operating unit.
Background technology
At present, the coupler of connection reducer and cart wheel shaft is used gear coupling more in the traveling mechanism of the larger traveller of little tonnage crane in bridge type.Gear coupling input and the drift angle that output is allowed very little (only having about half degree), radial displacement also very little (having only about 1mm).Equipment is when operation, because the dislocation of axial line has exceeded the allowed band value of gear coupling, certainly will will have influence on the service life of gear coupling, and gear coupling has defectives such as maintaining inconvenience, interchangeability difference in addition.
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, convenient for installation and maintenance, interchangeability strong and have the improvement structure of the little tonnage bridge crane operating unit of compensate function.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of improvement structure of little tonnage bridge crane operating unit; The mouth that comprises motor, motor connects drg through the brake wheel drive coupling, and drg is through the coupler connection reducer, and the output shaft of retarder connects the cart axletree through coupler; And cart wheel; It is characterized in that: the coupler of connection reducer and cart axletree adopts universal coupling, an end connection reducer output shaft of universal coupling, and the other end of universal coupling connects the cart axletree.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; Be about to universal coupling and substitute traditional gear coupling, universal coupling is compared with gear coupling, has simple in structure; Maintaining is convenient; Interchangeability is strong, particularly when the diaxon angle changes, and still can the normal delivery moment of torsion.Simultaneously, the reducer gear engagement abnormality that uses universal coupling that reason such as deviation is caused improves widely.Universal coupling can be eliminated unnecessary increment load; Can obtain enough compensation with universal coupling during decentraction between reducer output shaft and the cart axletree; Thereby also improved the service life of retarder; Universal coupling is also relatively more tolerant for diff-H, substandard requirement, and it all is very helpful for the layout of little tonnage bridge crane operating unit with assembling.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, motor; 2, drg; 3, coupler; 4, retarder; 5, coupler; 6, cart axletree; 7, cart wheel; 8, brake wheel drive coupling.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1; A kind of improvement structure of little tonnage bridge crane operating unit; The mouth that comprises motor 1, motor connects drg 2 through brake wheel drive coupling 8; Drg 2 is through coupler 3 connection reducers 4, and the output shaft 4-1 of retarder 4 connects cart axletree 6 and cart wheel 7 through coupler 5, and wherein said connection reducer 4 adopts universal coupling with the coupler 5 of cart axletree 6; One end connection reducer output shaft 4-1 of universal coupling, the other end of universal coupling connects cart axletree 6.
Because the utility model adopts technique scheme, be about to universal coupling and substitute traditional gear coupling, universal coupling is compared with gear coupling; Have simple in structurely, maintaining is convenient, and interchangeability is strong; Particularly when the diaxon angle changes, still can the normal delivery moment of torsion.
Simultaneously, the reducer gear engagement abnormality that uses universal coupling that reason such as deviation is caused improves widely.Universal coupling can be eliminated unnecessary increment load; Can obtain enough compensation with universal coupling during decentraction between reducer output shaft and the cart axletree; Thereby also improved the service life of retarder; Universal coupling is also relatively more tolerant for diff-H, substandard requirement, and it all is very helpful for the layout of little tonnage bridge crane operating unit with assembling.
