In such scheme, the two ends of described centering wheel shaft are respectively arranged with axis hole, regulate screw mandrel to be connected with centering wheel shaft through axis hole, and the end of adjusting screw mandrel is provided with step and blocks axis hole, and will regulate screw mandrel and centering wheel shaft to fix by nut.
In such scheme, described race is the cavity that is located at the openings at one side of centering wheeling support inside, and the size of race is greater than the diameter of centering wheel.
In such scheme, the cylindrical of described centering wheel protrudes from outside race, and its outstanding distance is greater than the maximum diameter of hole of microscler axis hole.
In such scheme, all wheel shaft is vertical arranges with centering for described adjusting screw mandrel.
In such scheme, described adjusting screw mandrel is threaded connection and is arranged on centering wheeling support, and is regulating the length that adjusting nut adjusting screw is installed on screw mandrel.
Operation principle of the present invention is that centering wheel and self-aligning roller bearing, feel relieved axle sleeve, bearing gland etc. are assembled into centering wheels, by centering wheel shaft, centering wheels is arranged in the microscler axis hole of centering wheeling support.In the two line screws up and down of centering wheeling support, each installs respectively an adjusting screw mandrel, and adjusting screw mandrel is fixed centering wheel shaft by the axis hole at the centering upper and lower two ends of wheel shaft, thereby realizes fixing centering wheels.By the adjustment to two adjusting screw mandrels, the wheels that can make to feel relieved move forward and backward, and have realized the adjustment to the gap between centering wheel and centering guide rail, can also by asynchronous adjusting two, regulate the length of screw mandrel simultaneously, and the perpendicularity of centering wheel axis is regulated.
Beneficial effect of the present invention is:
This centering wheel device install to adjust fixing after, can be efficiently and easily to the gap between centering wheel and centering guide rail and the perpendicularity of centering wheel shaft, adjust, with this, guarantee that centering takes turns the perpendicularity of cylindrical.
By reasonable adjustment, can guarantee to contact well between centering wheel and centering guide pass, extend service life of centering wheel and the guide rail of feeling relieved; Immediately the rationally adjustment to gap between centering wheel and guide rail, guarantees the centering pilot effect to lifting and translational frame, prevents blank sideslip in stove; Rationally adjust the gap between centering wheel and guide rail, also can prevent the generation of additional internal force in movable frame, improve the force-bearing situation of movable frame, extend the service life of framework.
