The working principle of self-aligning roller is what?
When roller when the center line of the vertical centerline and tape, take a conveyor belt and roller straightening machine any contact point M, rubber conveyor belt at a linear velocity V is equal with the rotation of the roller speed V9, due to no relative sliding velocity, as the static friction between them, the adhesive tape to the roller friction force F, and the friction force of the roller to tape Fd phase equilibrium, Fd and tape the centerline Angle a = 0, so when the roller when the center line of the vertical centerline and tape, rubber conveyor belt, horizontal stress, heat resistant conveyor belt running deviation when the roller can't automatic correction.
When roller center line and the center line of nylon conveyor belt is not vertical, straightening machine which roller forward Angle: when taking any M contact point, strong point at which a linear velocity V of conveyor belt, roller rotation speed for Vg, due to the roller centerline with the centerline is not perpendicular to the conveyor belt products, produce delta V, relative sliding speed between the two for the kinetic friction, high temperature resistant transport brings roller friction force F, and the relative sliding velocity. V in the same direction, to canvas conveyor belt roller friction force Fd and the relative sliding velocity V in the opposite direction; Because Fd and tape the centerline Angle a, tape with transverse force F, Fi and radial force, roller to tape horizontal correction force F,, = every sina, therefore, roller forward Angle after rectifying ability when it is rubber belt running deviation, self-aligning roller straightening machine is based on the design, manufacture.
About tapered self-aligning roller, two conical self-aligning roller cone roller rotating shaft installed in separate, two rotary rack through a linkage to realize synchronization, beam directly connected in the middle frame, belt running deviation after rotary frame around the rotating shaft rotates a certain Angle, the applying lateral thrust self-aligning roller to tape Fn, prompting wandering after the tape back in situ, realize automatic adjustment of the running wide tape, tape to run. Its characteristic is the original forward self-aligning changed the grooved roller of tapered roller, because the diameter of the tapered on both ends of the roller is big different, so the roller rotates, the size of the roller in contact with the tape head linear velocity is different, there is a speed difference, which changed the stress of the roller, the lateral thrust in the belt running deviation after the increase, self-aligning effect more apparent.
