Abstract
The present invention relates to a shaft coupling which is used between a driving shaft and a rotated cylinder body, which is particularly to suitable for connecting a driving shaft of a lift capstan and a winding drum, and other similar structures. The present invention is characterized in that an inner ring [3] arranged on a drive shaft contacts with an outer ring [1] connected with a cylinder body in a spherical surface mode, and a rotary sliding key [2] capable of transferring torque is arranged between the inner ring and the outer ring. The shaft coupling can bear large radial loading, transfer larger torque, and compensate deviation of shaft lines of two connected bodies within wider range. In addition, the utility model has the advantages of easy manufacture and installation, low cost and high safety and reliability, and is an ideal shaft coupling which is used between the low-speed heavy-load driving shaft and the rotated cylinder body.
Description
The invention belongs to the coupling that in Hoisting Machinery, is used for transmitting torque, more properly say it is to be used to hoist coupling between the rotary barrel of the live axle of hoisting mechanism and Passive part.
For the axial deviation between the rotary barrel that compensates live axle and Passive part, between live axle and rotary barrel, be provided with coupling usually." Barrel shaped roller coupling " of the 28th page of introduction of 91 years o. 11ths of " handling machinery " periodical is exactly a kind of more advanced coupling.It is mainly by the inner ring that is contained on the live axle, the outer ring that links to each other with cylindrical shell, and several cydariform rollers and the end cap that are contained between the inside and outside circle are formed, and transmit moment of torsion between the inside and outside circle by the cydariform roller.Though this coupling also can compensate the relative misalignment of axe of live axle and cylindrical shell, compensation ability is little, and if axis appearance inclination relatively, the cydariform roller will be pressed against a certain side, causes coupling to lose efficacy.Cydariform roller and its corresponding Internal and external cycle require that higher processing precision is arranged, and manufacture difficulty is big, and part is many, the cost height.
The purpose of this invention is to provide between a kind of inner ring and the outer ring is the coupling of sphere contact, and it can not only compensate the deviation of relative axis in a big way, and installation, easy to adjust, the use safety and reliability.
The present invention mainly is by the inner ring that is contained on the live axle, the outer ring that links to each other with the rotary barrel of Passive part, and the part composition that moment of torsion is delivered to the outer ring from inner ring, be the sphere contact between its inner ring and the outer ring, circular hole is radially arranged on the sphere therein, be provided with axial sliding keyway accordingly at another sphere and circular hole.More particularly, radially be processed with circular hole at the top of inner ring convex spherical exactly, on the spill sphere of outer ring, be processed with sliding keyway vertically.Otherwise, also can on the convex spherical of inner ring, be processed with sliding keyway vertically.On the spill sphere of outer ring, radially be processed with circular hole.The part of transmitting torque is the rotational slide key of being located between circular hole and the sliding keyway.This key can only be provided with one or be provided with two symmetrically, the cylindrical shape of an end of this key for can in circular hole, rotating, and the other end has two parallel side can sliding and the end face that is circular arc line with this two side faces intersection in sliding keyway.For inner ring and outer ring are assembled together, the outer ring can be done into two symmetrically along axis, during assembling, its two halves are buckled on the inner ring, and between parting plane, adding elastic sealing gasket (as oil-resistant rubber insert), two semicircles link together with bolt by the end cap at two ends again.Inner ring can also directly be produced on the live axle, is an integral body with live axle promptly.
Compare with known Barrel shaped roller coupling, this coupling can bear very big radial load, and the energy transfer larger torque can (be not more than 6 degree) and compensate live axle and the relative deviation that is rotated cylindrical shell in a big way.And can remove the axial constraint that the rotary barrel tail end supports, and cost is low, and part is few, and processing, mounting or dismounting and maintenance all are easier to, and safety and reliability.Be suitable for the live axle of low-speed heave-load and be rotated connection between the cylindrical shell, will produce good result the hoist workmanship of hoisting mechanism of raising.

Fig. 1 is an axial view of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the partial schematic diagram of the another kind of fit of rotational slide key between inside and outside circle.
Describe concrete structure of the present invention and working condition below in conjunction with accompanying drawing in detail with two embodiments.
(1) is the outer ring among the figure, is processed with two keyways that endwisely slip on its spill sphere symmetrically, and it is made up of two semicircles along the axis symmetry.(3) be inner ring, be processed with two circular holes radially symmetrically on its convex spherical, circular hole is corresponding with the sliding keyway on outer ring (1).(2) be the rotational slide key, this part one end is the cylinder that matches with circular hole on the inner ring (3), the other end side is processed with the slip surface that two parallel sliding keyways with on outer ring (1) match, and the top is an arc, cylindrical end is contained in the circular hole on inner ring (3) sphere and can rotates, end with two parallel sliding faces is contained in the sliding keyway of outer ring (1), and can slide relative.During assembling, rotational slide key (2) is contained on the inner ring (3), then outer ring (1) is buckled on the inner ring (3), between the parting plane of outer ring (1), add elastic sealing gasket (5).(7) for connecting the end cap of two semicircles, outer ring (1) and end cap (7) are linked together by bolt (4).(9) be the elastic sealing ring pad.(6) be the J-shaped rubber seal.On the sphere of outer ring (1) or inner ring (3), be processed with oil groove.(8) be grease fitting.The same with known Barrel shaped roller coupling, inner ring (3) is to be contained on the live axle with key connection or spline ways of connecting; There is the flange that links to each other with cylindrical shell the outer ring on (1), and flange machines away two strings symmetrically, and it just in time matches with big keyway on the shell flange (not drawing among the figure).
Fig. 3 is rotational slide key (2) another fit between inner ring (3) and outer ring (1).On the convex spherical of inner ring (3), be processed with sliding keyway vertically, on the spill sphere of outer ring (1), radially be processed with circular hole.The cylindrical end of rotational slide key (2) is contained in the circular hole on the sphere of outer ring, and the end with two parallel sliding faces is contained in the sliding keyway on the inner ring sphere, and this fit also is in full force and effect.
