3-dimensional strip winding system for special giant all-steel radial otr tire

Abstract

3-D Strip Winding System for a special giant all-steel radial OTR tire comprising: a movable base plate, a pivoting device, a support, a winding and applying device, and a bracket. The pivoting device comprises a spin orbit of an external gear ring, a positioning and rotating inner race, a support plate, a servo motor, and a drive gear. The spin orbit of an external gear ring is fixed on the plane of movable base plate. The positioning and rotating inner race is flexibly attached inside the spin orbit of an external gear ring. One end of the support plate is fixed to the positioning and rotating inner race. The servo motor is fixedly disposed on the support plate, the output end of which is connected with the drive gear after passing through the support plate. The drive gear is engaged with the outer edge of the spin orbit of the external gear ring.
