T/WJDGC 0022-2024 Rolling bearing fault detection device

Scope

Scope: This document specifies the terms and definitions, performance and applications, technical specifications, component descriptions, fault detection, device diagnosis and monitoring, operation and maintenance, and precautions for rolling bearing fault detection devices. This document is applicable to rotating equipment operating at a rated speed of no more than 5000 r/min in laboratories and production enterprises. Main technical content: 3.1 Fault: A phenomenon in which the equipment "loses its specified function" or endangers safety during operation. 3.2 Rolling bearing: A device that converts sliding friction between the rotating shaft and bearing seat into rolling friction, significantly reducing friction losses. Rolling bearings are generally composed of an inner ring, an outer ring, rolling elements, and a cage. 3.3 Test apparatus: An indispensable device for scientific research or industrial experiments. It can simulate real environments, adjust and measure various parameters of the experimental object, and obtain relevant data and information. The development and application of test apparatuses not only promote scientific progress but also provide technical support for industrial production and serve as a basis for line improvement. 3.4 Bearing failure: Various abnormal phenomena in the operation of bearings that affect their performance and service life and have a certain impact on the operation of equipment. 3.5 Test head: A device used in testing or measurement processes, typically in conjunction with testing machines or measurement equipment. Its specific structure and functions vary depending on the application field, but generally include sensing, measurement, and data transmission capabilities. 3.6 Transmission system: An intermediate device that transfers power and motion from the power source to the actuator system, serving as a bridge connecting the power system and the actuator system. It transfers power to the actuator system thr
