Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.Should be understood that, embodiment described herein only is used for description and interpretation the utility model, is not limited to the utility model.
The utility model provides a kind of coupling, and this coupling comprises the first half ones that are connected to power intake and clutch end and the second half ones, and wherein, in described the first half ones and described the second half ones, one is rigid portion, and another one is spring section 3.
in above-mentioned coupling, the first half ones of coupling are connected with a clutch end and power are passed to the power intake that is connected with the second half ones through the first half ones and half one of being connected, especially, one in the first half ones and the second half ones is rigid portion, another one is spring section 3, like this spring section 3 and rigid portion interaction transmission power in can by resiliently deformable to the power intake that is connected in spring section 3 or clutch end and rigid portion between radially, axial and angle error compensates, thereby power intake and the clutch end that connects by described coupling played the correction effect.
Under preferable case, described spring section 3 is set on rigid portion, spring section 3 is set in the support that is subject to rigid portion on rigid portion, and reduced it in open space and be subjected to the limited degree of spatial structure because spring section 3 is arranged on, thereby spring section 3 can be set to have larger volume, thereby makes coupling can have larger centering capacity.
In the present embodiment, particularly, described rigid portion comprises rigidly connected axle sleeve 1 and joint sleeve 2, and spring section 3 is set in the end away from axle sleeve 1 of joint sleeve 2.One in described power intake and described clutch end is connected in spring section 3, and another one is connected in axle sleeve 1.
Further, joint sleeve 2 away from a side of axle sleeve 1 on along circumferentially being provided with a plurality of tapped holes 5, correspondingly be provided with a plurality of bolt holes 4 that radially extend on spring section 3, bolt passes bolt hole 4 and is fixed in tapped hole 5 so that spring section 3 is fixed on joint sleeve 2.In this case, spring section 3 is removably fixing with rigid portion, conveniently in time change when spring section 3 or rigid portion damage, and the position that is screwed into by adjusting bolt in tapped hole 5, can also adjust the compression degree between spring section 3 and coupling band 2, coupling is adjusted to the optimum state.
And, as a kind of mode of execution, can be provided with a plurality of the first axial through hole 6, the first links 7 along this spring section 3 on spring section 3 and pass the first through hole 6 so that spring section 3 is connected with power intake or clutch end; And particularly, bolt hole 4 is provided with first through hole 6 along the circumferential equally spaced layout of spring section 3 between two adjacent bolt holes 4.In this case, facilitate the dismounting of spring section 3 and rigid portion and clutch end or power intake, and conveniently suitably adjust spring section 3 according to actual conditions.
Rigid portion can be set to suitable arbitrarily form, for example, axle sleeve 1 and joint sleeve 2 have respectively flange at an end that is connected with each other, be provided with accordingly respectively the second through hole 8, the second links on flange and pass successively the second through hole 8 on two described flanges so that axle sleeve 1 is connected with joint sleeve 2.
