Friction strong reversible self-aligning roller

Abstract
A kind of friction strong reversible self-aligning roller, which is improved on the basis of the original structural frame, beam, vertical axis seat, pillar, load-bearing roller, side bracket, damping roller and deflection adjustment stop mechanism. The load-bearing rollers on both sides are The single-link structure is changed to a double-link roller, and a friction braking mechanism is added below it, which combines the end-face latch type stop and the cylindrical braking type into one. When the tape deviates, it is stopped by the damping The idler roller transmits the deviation signal to the deviation adjustment stop mechanism and the friction braking mechanism respectively, so that the friction torque on both sides of the idler roller assembly is unbalanced, causing it to rotate around the vertical axis seat, so as to realize the deviation adjustment of the belt. Purpose. The utility model has reasonable structure, remarkable offset adjustment effect, small wear of parts and long service life of the whole machine.

The utility model changes the load-bearing rollers on both sides from single-link rollers to double-link rollers under the condition of ensuring sufficient active torque for the roller assembly, so that the rotational inertia of the stopped part is greatly reduced; and the contact relationship between the stop pin and the block is improved from the original line contact to surface contact stopping; at the same time, a friction braking mechanism is added to combine the outer circle braking and the end face pin stopping into one, thereby reducing the roller rotation speed during the stopping process, thereby reducing the impact force during the stopping process. Therefore, the advantages of this mechanism are: reasonable structure, good braking effect, can meet the active torque requirement for the belt deviation adjustment, and will not cause destructive wear to the entire mechanism, thereby extending the service life of the whole machine.
