for weldingRoller standGenerally speaking, the rollers and weldments are round, and all the rollers are the same length, and the axes are parallel. Then the function of the active sprocket weldment is the force on the welding, and it is also the reaction force of the rolling sprocket on the weldment, which is what everyone calls the circumferential force. That is to say, if the weldment rotates around the axis, its axis will not move up and down. If there is serious damage to the roller frame in one place, for example, there is an error when installing the welded roller frame, and if the shape of the weldment is different or irregular, then the front and rear rollers will be very different. If one is higher, it will be lower, and the axis of the roller and the axis of the weldment will not be parallel. In this way, the shaft will move up and down where the driving sprocket of the weldment contacts the driven sprocket.

Now let's talk about the results of the analysis: the speed of the weldment shaft moving up and down is directly proportional to its rotational speed. If there are more rollers deflected at the same angle, the weldment shaft will move up and down faster and faster. Also, if the left and right sides of the weldment are too heavy, the speed of the shaft will also change. weldingRoller standIf the axes are on the same plane, the distance between the rollers will have no effect on the speed of the axis moving up and down. Therefore, if there is any error when installing the roller frame, it will not work.
