Technical Field

[0001] The utility model relates to the technical field of thrust bearings, in particular to a spherical surface support strengthening device for a thrust bearing of a vertical mill reducer. Background Art

[0002] Vertical mill reducer is a large-scale grinding equipment, widely used in cement, electric power, metallurgy, chemical industry, non-metallic minerals and other industries. The thrust bearing support of the vertical mill reducer is a device used to support and stabilize the thrust bearing of the vertical mill reducer. The thrust bearing is an important component of the vertical mill reducer. It bears the upper loading force from the transmission disc and the weight of the components, and transmits it to the reducer body.

[0003] At present, when the thrust bearing of the vertical mill reducer is installed above the mounting disc frame, two sets of anti-weight bolts are usually used to lock the anti-weight plate at the disc frame, and then the end of the anti-weight bolt head can be inserted into the bottom groove surface of the thrust bearing for installation. The thrust bearing point of this installation method is double-point force, and its life is short after long-term wear and use, which leads to a more frequent maintenance cycle of the thrust bearing. For this reason, we propose a spherical support reinforcement device for the thrust bearing of the vertical mill reducer. Utility Model Content
