Why be called synchronous self-centering, be because take the big backing ring of bearing that the crank connecting link group of symmetrical structure determined to be connected with it except the swing degree of freedom that level is arranged, it should be definitely to keep horizontality, can not tilt, and it about, hang down and to fall in the process moment that evenly presses down formation by the big backing ring of bearing and pass to the chute gudgeon and form horizontal torque, can not produce any radial component.If on the bush ring of the big backing ring overcoat of bearing, be provided with radial guide and limit wheel, and set up spacing guide path to match at cabinet shell, then can realize driving the big backing ring of process centre bearer steadily absolute and level about, can be described as the cooperation that has solved two rotary freedoms of complexity with the simplest structure.
Further specify below in conjunction with accompanying drawing and the objective of the invention is how to realize.
