Abstract

The article describes the design and operational factors leading to failures in mounting groups of the modern auger equipment. At the same time, the operating experience was considered of using antifriction bearings with solid lubricant antifriction filler (AFZ) having self-lubricating and self-sealing properties in various mounting groups. The changes in bearing clearances with AFZ as potential sources of high-frequency oscillations were assessed, also potential sources of low-frequency high-amplitude oscillations were identified in the design. As a result, the impact of mounting groups of the auger equipment on the change of the availability condition in the process of performance was assessed using vibration-based diagnostics method. The design of the mounting group with AFZ without end covers was proposed. Application of such a mounting group increases the service life of bearing support in the areas inaccessible for maintenance and repairs resulting in reduced labor intensity, energy and financial costs.
