Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the coupling that can connect fast-throw off provided by the utility model, comprise the half-coupling a2 be connected with driven shaft 7 and the half-coupling b6 be connected with driving shaft 8, on the drive plate of half-coupling a2 and half-coupling b6 along circumferentially respectively correspondence several circular holes are set, eccentric pin shaft 1 is set in corresponding circular hole, be provided with rolling bearing 4 in circular hole on half-coupling b6 drive plate, the cylndrical surface of eccentric pin shaft 1 coordinates with the inner ring of rolling bearing 4.
The core component of coupling provided by the utility model is an eccentric pin shaft, as shown in Fig. 2-1, Fig. 2-2.Comprise the cylindrical body A9 and the cylindrical body B10 that mutually depart from axle center, the cross-sectional diameter of cylindrical body A9 is greater than the cross-sectional diameter of cylindrical body B10, and the axle center deviation of the axle center of cylindrical body A and cylindrical body B is e.The end of cylindrical body B10 is cone, angle theta, and the head rounding, diameter d is determined by transmitting torque and the strength of materials.
In the present embodiment, half-coupling b6 drive plate is provided with 4 circular holes, on the circumference that to be distributed in diameter be D, in order to assemble rolling bearing 4.Two glands 3 compress rolling bearing 4, realize axially locating.The cylndrical surface of the cylindrical body A of eccentric pin shaft coordinates with bearing inner race, and circlip 5 is the axial restraint of eccentric pin shaft 1, thus eccentric pin shaft cylindrical body B10 can rotate around the axle center of cylindrical body A9.
As shown in Fig. 3-1,3-2, in the present embodiment, the drive plate of half-coupling a is provided with 4 circular holes 11, and circle hole radius is d, and circular hole is distributed on the circumference that diameter is D, with eccentric pin shaft, coordinates, and circular hole one end is provided with the chamfering of angle α.
During assembling the movement locus of eccentric pin shaft as shown in Figure 4, the distribution circumference that circumference S1 is 4 circular holes on half-coupling a disk, diameter D.The axle center that circumference S2 is eccentric pin shaft cylindrical body A is at the distribution circumference of half-coupling b, diameter D.Roundlet S31, S32, S33, S34 are the rotation tracks in the axle center of 4 eccentric pin shaft cylindrical body B, diameter 2e.When the main driven shaft axle center does not overlap limit deviation e, roundlet S31, S33 are tangent with circumference S1 respectively, and under the effect of external force, eccentric pin shaft can rotate to the position coincided with axis hole, and therefore two coupling axle center permissible error scopes are not more than e.
When main driven shaft generation deviation, and, while being not more than e, circumference S1 must intersect with 4 roundlet S31, S32, S33, S34, now adjust the relative position (adjusting angle is 90 degree) of two half-couplings, can make 4 holes of eccentric pin shaft and half-coupling a match, realize connecting fast.Consider the error in the coupling course of working, the decentraction scope of main driven shaft should be less than e.
