Description

Technical Field

[0001] The utility model relates to the technical field of float glass manufacturing equipment, in particular to an annealing furnace bridge transmission device. Background Art

[0002] The forming process of float glass production is completed in a tin bath with protective gas. Molten glass flows continuously from the tank kiln and floats on the surface of the relatively dense tin liquid. Under the action of gravity and surface tension, the glass liquid spreads and flattens on the tin liquid surface to form a flat upper and lower surface. After hardening and cooling, it is led to the transition roller table. The rollers of the roller table rotate, pulling the glass ribbon out of the tin bath and into the annealing kiln. After annealing and cutting, flat glass products are obtained.

[0003] The annealing kiln drive roller is the main equipment of the glass line. With the development of the industry, the cost competition pressure is getting greater and greater, the single-line output is getting larger and larger, and the length of the annealing kiln is getting longer and longer. However, the length is too long, which causes the foundation sinking, the expansion joint expansion and contraction of the civil engineering. The current solution is to connect the transmission shaft through the shaft with a sleeve block key. The traditional sleeve block key connection transmission through shaft method is prone to excessive straightness, resulting in the breakage of the transmission shaft and affecting production.
