Abstract
The utility model relates to a resilient tooth gear coupling, comprising an external tooth sleeve, two end covers which are respectively installed on both ends of the external tooth sleeve and two gears which are installed in the external tooth sleeve. The utility model is characterized in that under the precondition that the bending strength of teeth is guaranteed, the tooth gaps of the gears are deepened, therefore, the rigidity of teeth is reduced, the gears can contact the tooth surface of the external tooth sleeve better, and the capacity of transmitting torque of the coupling is improved.
Description
The utility model belongs to the rigid coupling technical field.
In at present general various coupling, the moment of torsion maximum that gear coupling transmits under measure-alike situation.But the shaft axis disalignment of both sides during owing to machining error and installation, cog-wheel coupling can cause the part flank of tooth contact of having only the part tooth when work, when transmitting torque is big, there is the contact stress of the local flank of tooth can surpass allowable stress, thereby limited the performance of gear coupling performance, be difficult to satisfy the usage requirement under some specific conditions.
The purpose of this utility model provides a kind of more gear coupling of high pulling torque that can transmit under the same size situation.
The utility model is the improvement to existing gear coupling, it has external tooth cover, is installed in the end cap at external tooth cover two ends and is installed in the interior gear of external tooth cover, its structural feature is under the prerequisite of the resistance to flexure that guarantees tooth, below the root circle between wheel tooth, also be processed with groove, in order to reduce the rigidity of tooth, make tooth have certain elasticity.
The tooth that the utility model has the advantages that gear has certain elasticity, easy deformation when being subjected to bigger load, more toe joint is touched, thereby strengthened the gear gross contact area, the corresponding maximum contact stress that reduced is under the constant situation of size and other condition, improved the ability of coupling transmitting torque, thereby improved the usability of gear coupling, satisfied the usage requirement of many specified conditions, and the accuracy of manufacturing of gear also can suitably reduce.
Fig. 1 is a middle longitudinal section of the present utility model;
Fig. 2 is the A-A sectional view among Fig. 1;
Fig. 3 is used gear of the utility model and the used gear structure comparison diagram of prior art, and left-half is the prior art structure among the figure, and right half part is the used gear structure of the utility model.
The embodiment that accompanying drawing provides, its basic structure and normally used straight-tooth or crown gear coupling are roughly the same, be that left and right two gears 4,5 are installed in external tooth cover 1, be separately installed with end cap 2,3, in the groove in end cap 2,3 O-ring seals 6 is housed at external tooth cover 1 two ends.Its structural feature is to have deepened between cog on the basis of existing gear, promptly also is processed with groove 7 or finedraw below root circle, has increased dedendum of the tooth relatively, to reduce the rigidity of tooth, increased the elasticity of tooth, made it under the condition of same size, can transmit bigger moment of torsion.
