One end of the transition roller 6 is provided with a transmission mechanism, the transmission end is called as the transmission end of the transition roller 6, the other end is called as the driven end, and the transition roller 6 can stably rotate under the driving of the transmission mechanism to realize the bearing and traction of the high-temperature glass belt. Normally, the transition roller shaft 1 at the transmission end of the transition roller 6 is fixed in the inner ring of the support bearing 2 and is clamped by a bearing top screw, and the circumferential outer side of the transition roller shaft 1 at the driven end is provided with a sliding key groove 11 arranged along the axial direction of the transition roller shaft 1. The transition roller shaft 1 at the driven end of the transition roller 6 is arranged in the inner ring of the other supporting bearing 2, the transition roller shaft 1 and the inner ring of the supporting bearing 2 are not fixed, when the transition roller 6 expands due to heat or contracts due to temperature reduction, axial sliding can be generated between the transition roller shaft 1 at the driven end and the inner ring of the supporting bearing 2, stress borne by the transition roller shaft 1 and the supporting bearing 2 is eliminated, and shaking of the transition roller 6 during rotation is prevented. The driving key 3 is fixed on the inner side surface of the inner ring of the support bearing 2 along the axial direction of the support bearing 2, and when the support bearing 2 is installed on the transition roller shaft 1, the driving key 3 is positioned in the sliding key groove 11. When the transition roller 6 rotates, the inner ring of the support bearing 2 can be driven to rotate through the matching of the sliding key groove 11 and the transmission key 3, and the transition roller shaft 1 is prevented from being abraded due to the fact that circumferential sliding is generated between the transition roller shaft 1 and the inner ring of the support bearing 2. Because the inner ring is not driven to rotate by the friction force between the transition roller shaft 1 and the inner ring of the support bearing 2, the interference magnitude of the fit between the transition roller shaft 1 and the inner ring of the support bearing 2 can be reduced, even a certain amount of clearance fit can be used, and the friction force of the axial sliding between the transition roller shaft 1 and the inner ring of the support bearing 2 is reduced. The power key 3 is also axially slidable in the slide key groove 11, and can prevent the transition roller 6 from rattling due to sliding between the transition roller shaft 1 and the inner ring of the support bearing 2 without interfering with the axial sliding of the transition roller shaft 1 while driving the inner ring of the support bearing 2 to rotate.
