Specific embodiment
Hereinafter, will be described in detail according to bearing block center of the present utility model with reference to accompanying drawing and exemplary embodiment
Stress type spiral tensioning device and ribbon conveyer system.
In an exemplary embodiment of the present utility model, as shown in figure 1, a kind of bearing block center stressed formula spiral draws
Tight device includes screw rod 1, and screw rod 1 is each passed through nut 2 and nut shaft 3, and screws in the one end for hanging first 10.Screw rod 1 with hang first 10
Connected by wearing pin bolt 11, nut 12 and packing ring 13.Flange shaft bearing 5 is fitted together, then led to bearing 4, nut shaft 3
Cross back-up ring 7 and determine bearing clearance, tighten round nut 9 and positioning is completed by stop washer 8.First 10 are hung to be slided with bearing by pivot pin 14
