Description
Technical field
The utility model relates to coupling technical field.
Background technique
In most machinery, be fastenedly connected and be all rigidly connected, between relative link, must not displacement be had, as common coupling, be by two part bolton, such installation requirement concentricity is high, slightly error, machinery will shake, and the life-span is not long.In flexible connection, the relation of relative link both Constrained or transferring power, can have again relative displacement to a certain degree.In prior art, the common measures taken of the flexible connection of machinery is between two-part of coupling, uses slide block, spring column pin, dowel or universal joint etc., namely delivers power, also meet the usage requirement of equipment.But above-mentioned measure can not overcome because transmission shaft is long, dynamic balancing is difficult to ensure, causes the situation that axle head weares and teares.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of coupling that flexible bearing is housed, and has in the operation process of major axis connection device, automatically can reduce the feature that major axis stress causes the axle head degree of wear.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of coupling that flexible bearing is housed, comprise the flexible bearing be positioned between left flange plate and right flange plate, described flexible bearing comprises urceolus, axle bush sleeve, spheroid sleeve and spheroid rotating disk; The right-hand member of described spheroid rotating disk connects coaxial left spheroid and right spheroid, and the diameter of described right spheroid is greater than left spheroid, is all connected by plane between spheroid rotating disk with left spheroid and between left spheroid with right spheroid; Described spheroid sleeve inner is provided with connected left part through hole and right part blind hole, and the diameter of described left part through hole is greater than the diameter of right part blind hole, and the wall of the spheroid sleeve between left part through hole and right part blind hole is provided with uniform rotation pin-and-hole; Between the left side and inwall of right part blind hole, be provided with the sphere chamfering suitable with right spheroid, the right flank of right spheroid and sphere chamfer contact, the roll pin be connected with right spheroid is installed in described rotation pin-and-hole; Described axle bush sleeve is arranged between spheroid sleeve and urceolus, and the periphery of axle bush sleeve is provided with the sphere towards outer lug, the inwall of urceolus and the sphere of axle bush sleeve periphery suitable.
To the further improvement that the utility model does be: the left end of described left flange plate is connected with electric machine main shaft or middle joining shaft, left flange plate is connected with spheroid rotating disk left end by bolt; The right-hand member of right flange plate is connected with middle joining shaft, and right flange plate is connected by the right-hand member of bolt with spheroid sleeve.Supported rod erecting is connected in described urceolus bottom.
The beneficial effect adopting technique scheme to produce is: the axle head wearing and tearing that the flexural stress that the utility model can reduce major axis connection by the Self-aligning effect of flexible bearing causes, when flexible bearing is by major axis effect, swing can be there is within the scope of several angle between right spheroid and spheroid sleeve to eliminate stress, thus make major axis connection device in operation process, automatically reduce the axle head degree of wear that major axis stress causes.
