Therefore, the eccentric inner ring is installed and fixed on equipment through the eccentric through hole or the threaded through hole, and the eccentric inner ring structure can also adopt the integral structural design of the eccentric screw and the inner ring.
Two belt edge grooves are respectively formed in the two ends of the outer diameter of the peripheral surface of the groove-shaped part of the outer ring. Therefore, the belt edge groove corresponds to the bulge at the edge of the belt, and the belt is further prevented from outwards deviating.
Two sealing grooves are respectively arranged at the two ends of the inner diameter of the outer ring at the groove shape of the outer ring, and sealing rings are respectively arranged at the sealing grooves.
The utility model has reasonable structural design, convenient assembly, good stability and sealing performance, low noise, large load, long service life and high operation precision; the tensioning wheel bearing is suitable for being used as an integral tensioning wheel bearing of a single-multi-head embroidery machine and the structural improvement of similar products.
