[0002] The driven split traction roller is an important process equipment for the production of TFT-LCD liquid crystal glass. Since the driven split traction roller of the liquid crystal substrate glass has no driving device, the requirements for the rotation flexibility and floating flexibility of the traction roller are relatively high; Some driven split traction rollers have a unilateral suspension structure, and the supporting bearings are simultaneously subjected to horizontal and vertical forces. When the traction roller rotates, a certain resistance is generated. At the same time, due to the high temperature of the bearings, the particles produced by oxidation and wear cannot be removed in time, and the There will be a certain resistance. These two reasons cause the traction roller to rotate not very smoothly, and sometimes the non-rotation phenomenon occurs. The friction between the roller and the glass plate produces a large mechanical resistance, which affects the quality parameters such as warpage and stress of the glass.

In the production process, the glass plate will have a certain swing due to cutting and breaking or air flow fluctuations. It is required that the driven traction roller also swing with the glass plate, but it must also prevent the glass from shaking too much and breaking the plate. The existing traction The floating structure of the roller is complicated. The force of the roller counterweight is transmitted through the three-point lever structure, and the sliding friction pair such as the sliding bearing is used, so the friction force to be overcome is relatively large, and the floating of the traction roller is not very flexible.
