Cog-wheel coupling is extensive use of in mechanical transmission fields, and its effect is the transmission of moment of torsion between the diaxon.Existing cog-wheel coupling has two transmitting assemblies A, B as shown in Figure 1 by fitting bolt 1 connection of flange portion separately, and its junction plane D is a smooth flat.Two transmitting assemblies A, B connect its transmission principle by flat key and transmission shaft interference fit respectively: transmission shaft by flat key transfer torque to → external tooth cover 3 → external tooth cover 3 of transmitting assemblies B and internal tooth casing 4 be by internal tooth casing 6 by fitting bolt transmitting torque → transmitting assemblies A of Hindley worm gear transmitting torque → transmitting assemblies B and transmitting assemblies A → be delivered to the external tooth cover 5 of transmitting assemblies B → transfer torque to working portion by flat key by the sphere tooth.
Cog-wheel coupling in the course of the work, because it act as the moment of torsion that transmits between the diaxon, therefore, its each part all can be subjected to the effect of power, harm such as fatigue, wearing and tearing, fracture occur, on-the-spot its main degradation phenomena of proof that uses shows: loosening, the fracture of fitting bolt; The sphere odontotripsis is shaved light.The consequence that causes is: broken away from by drive part and drive part, therefore runaway condition occurred by transmission unit branch.Fig. 2 is a crane hoisting power transmission schematic diagram; from the way, can find out when the cog-wheel coupling inefficacy; though there is break protection reel out of control; but in the actual production process,, can't know cog-wheel coupling lost efficacy (bolt cuts off or the flank of tooth is shaved light) because the hoist driver operates at driver's cab; therefore when the coupling inefficacy occurring; break still is in open mode, and freely falling body will appear in the elevator thing of hanging oneself, and leads to the serious accident that can't retrieve.
When the cog-wheel coupling fitting bolt is cut to all 30% the time, because torsional interaction, particularly during oepration at full load, fitting bolt can occur and all break suddenly, cog-wheel coupling was lost efficacy.Under the prerequisite that does not change transmitting torque, for avoiding loosening, the cut-out of cog-wheel coupling fitting bolt, it is unexpected that the accident that all breaks can not appear yet in case most of bolt cut-out takes place, and avoid the flank of tooth because the cog-wheel coupling inefficacy of light time is shaved in wearing and tearing, need for this reason, the design people has invented a kind of cog-wheel coupling of safety and reliability, can sketch structure of the present utility model or characteristics of principle.
The model utility content
For addressing the above problem, the utility model provides a kind of connecting bolt that can prevent loosening, improves transmission intensity, the rate of wear of having slowed down engaging tooth, and normal and safer, reliable cog-wheel coupling increases the service life.
For finishing above-mentioned task, the utility model adopts following technological scheme:
A kind of cog-wheel coupling comprises the transmitting assemblies that a pair of structure is identical, and transmitting assemblies comprises internal tooth casing and the external tooth cover that cooperatively interacts, two transmitting assembliess are coaxial, by nut that the external tooth cover of two transmitting assembliess is fixedly connected, it is characterized in that the cooperation of two external tooth covers adopts concaveconvex structure to cooperate.
Wherein, preferably, the concavo-convex bound fraction that concaveconvex structure cooperates is a transition fit.
Wherein, preferably, the fitting surface of two external tooth covers has a projection that cooperates with a diametric and groove vertical with the groove diameter along diametric groove respectively.
Wherein, preferably, external tooth puts and has a pair of concaveconvex structure that cooperatively interacts and cooperate in the gear matched place of the interior external tooth cover that cooperatively interacts same diametric, along the height of the concavo-convex cooperation of the diametric(al) height greater than gear matched.

Embodiment
Below in conjunction with the drawings and specific embodiments cog-wheel coupling of the present utility model is further described.
As shown in Figure 3 and Figure 4, the gear coupling structure of the structure of cog-wheel coupling of the present utility model and prior art is basic identical, and improvements are that the fitting surface of the outer ring 11,12 of transmitting assemblies is changed into the spline fitted of concaveconvex structure by original plane.Outer ring 12 have groove 13 on the same diameter in conjunction with end face, and on the diameter of groove 13 place diameter Vertical direction a pair of projection 14 is arranged.Groove 13 and projection 14 sizes can cooperatively interact.Equally, relevant position in the outer ring 11 of another transmitting assemblies has projection and the groove that cooperates with the groove 13 and the projection 14 of outer ring 12, and concavo-convex bound fraction is a transition fit, thereby has certain transmitting torque effect, and the position of concavo-convex junction plane will be according to inside and outside tooth matching design.Its effect: born the part moment of torsion on the one hand, fitting bolt is difficult for looseningly on the other hand, even under the situation that most of bolt cuts off, the remaining part bolt is complete rupture suddenly not also, articulation hole on the outer ring flange can not be out of shape, and original transmitting torque can not be affected.
As shown in Figure 5, another improvements of cog-wheel coupling of the present utility model are that there is a pair of recessed dovetail shaped chute 20 at the external tooth cover 11 inboard same diameter two ends of transmitting assemblies, and the degree of depth of chute 20 is greater than tooth depth; The slide block 21 of the projection that a pair of and above-mentioned recessed chute 20 cooperates is arranged on each internal tooth casing 15 outside, is Spielpassung between the two.Another transmitting assemblies adopts identical slide block cooperating structure.Mating part is inoperative under the normal condition, when inside and outside tooth surface abrasion is shaved the light time, stops inside and outside tooth cover freely to rotate (emergency should be changed coupling immediately) by slide block structure, prevents that coupling lost efficacy, and caused the accident.
