Abstract

The invention relates to a rolling shaft supporting bearing of a hot air rotary furnace. The rolling shaft supporting bearing comprises a bearing pedestal body (1), the bearing pedestal body (1) comprises a circular tube segment (1.1), a shaft hole (1.3) is formed in the center of the circular tube segment (1.1), a circular boss (1.2) is arranged at the upper end of the circular tube segment (1.1) and provided with multiple cooling holes (2) in the radial direction of the circular boss (1.2), and a reinforcing ring (3) is arranged at the lower end of the circular tube segment (1.1). According to the rolling shaft supporting bearing of the hot air rotary furnace, expansion is not liable to be generated when the rolling shaft supporting bearing is heated, clearance changes between a rolling shaft and the bearing pedestal can be effectively prevented, and the rolling shaft running reliability is guaranteed.

Description

technical field [0001] The invention relates to a roller support bearing for a hot air rotary furnace, which belongs to the technical field of baking equipment. Background technique [0002] With the rapid development of social economy and the continuous improvement of people's living standards, various snack foods such as bread have entered ordinary families, and the bread industry has also obtained opportunities for rapid development. While food wholesale factories, bakery chain stores and supermarkets are appearing in large numbers, hot air rotary ovens, a baking machine that uses a whole car in and out, are widely used in French bread, toast, meal bags, In the baking process of Cantonese-style moon cakes, cookies, Danish bread, French small meal buns, puffs, heavy oil cakes and other products. [0003] During the working process of the rotating roller of the current hot blast rotary furnace, due to the high working environment temperature, the roller bearing seat is eas...
