According to prior art, in order to guarantee the normal operation of rotary connector, two or two above bearings are all housed in rotary connector, like this, the structure display of rotary connector obtains very complicated, and how the quantity of bearing has just determined that the length of rotary connector is longer, thereby reduced the bearing capacity of rotary connector, after rotary connector is subject to laying tension, when crossing pulley, can be subject to very large moment of flexure, rotary connector can be damaged, and is unfavorable for safe construction.
Model utility content
The technical problems to be solved in the utility model is, overcomes the defect of above prior art, thus provide a kind of simple in structure, can reduce the large and safe and reliable sphere Anti-bending rotation connector of body length bearing capacity.
Technical solution of the present utility model is, the sphere Anti-bending rotation connector with following structure is provided, it comprises is equipped with respectively front axle and the rear axle that cover has the bearing pin of guard ring, it also comprises that to be positioned at front axle and rear axle inner and be connected the axle of front axle and rear axle, described axle body stretches in front axle, described spindle nose stretches in rear axle, the axial limiting shaft shoulder is established in described axle body end, near shaft shoulder cover, there is thrust-bearing, near thrust axis bearing sleeve, there is outer spherical surface back-up ring, front axle away from end part of pin shaft open pore in be provided with internal thread, in screw-internal thread fit, be provided with externally threaded inner ball surface back-up ring, described inner ball surface back-up ring and outer spherical surface back-up ring sphere coordinate, in the end through hole of described rear axle away from bearing pin, be provided with internal thread, described spindle nose is provided with outside thread, internal thread coordinates with outside thread, front axle and rear axle two ends are respectively provided with bearing pin.
Adopt after above structure, the utility model compared with prior art, have the following advantages: the utility model has only adopted a thrust-bearing, simple in structure, reduce the length of sphere Anti-bending rotation connector, thereby increased bearing capacity, axle body and the spheric structure that adopts sphere inner shield ring and the outer back-up ring of sphere to match being connected of front axle, when sphere bending resistance rotor is worked, make axle can bear power axially and radially, safe and reliable.
As preferably, described rear axle is provided with a plurality of screw-threaded counterbore along circumferential arrangement, and each described screw-threaded counterbore is provided with the first Cock screw, prevents spindle nose radial-play.
As preferably, the top of described spindle nose is provided with for the in-line groove of axle is installed, and can play installation with a word, convenient and swift.
As preferably, between described front axle and rear axle, leave the gap of guaranteeing energy bending between front axle and rear axle, can bear certain moment of flexure, the life-span is longer.
As preferably, described rear axle is 2 centimetres away from the straight flange of bearing pin and the distance of front axle, and the angle of bending is moderate, does not affect its anti-bending strength.
As preferably, described front axle is provided with a plurality of screw-threaded counterbore along circumferential arrangement, and each described screw-threaded counterbore is provided with the second Cock screw, prevents the outer back-up ring radial-play of sphere.
As preferably, the front-end face of described axle body is sphere, and axle rotation is more smooth and easy, and axle can not produce axial float.
