“…Machines and aggregates are subjected to periodic diagnostic examination and testing to determine the technical state of mechanical nodes by methods of nondestructive control. There is a large number of control techniques, but the main condition is to provide reliable test results with minimal energy consumption, which is achieved by the correct choice of control method [445]. The automation of the control process is a major way to eliminating people floating on the results of measurements, as well as ensuring the efficiency of data processing and obtaining results, which increases the energy efficiency of diagnostic methods.…”

“…A study was carried out on the pattern of changes in the heating temperature of the rolling bearings in a screw-cutting lathe [25] and a vertical drilling machine during tests without load. It was confirmed that under a regular heating mode, the heating rate of the rolling bearings in a spindle assembly in an efficient technical condition does not exceed 1.1 °C/min.…”

An improved method of passive thermal control has been proposed in order to operatively assess the technical condition of rolling bearings, based on studying the heating rate of a bearing. The values of the heating rate of ball, roller, and conical rolling bearings, as well as ball separators, have been determined empirically. It has been shown that the discrete limit heating rate values derived under the regular heating mode of mechanical reducers during stand tests are suitable for use as a diagnostic criterion for rolling bearings. Based on the heating speed criterion for mechanical reducers, it is possible to perform an operative assessment of the technical condition of rolling bearings of different types during the operation of equipment for different purposes. It has been established that for a rolling bearing in a working technical condition the heating rate under a regular heating mode does not exceed 1 °C/min. The resulting value corresponds to the diagnostic criterion for the heating rate of mechanical reducers in a working technical condition of ϑ n ≤1.1 °C/min. Using a diagnostic parameter of the heating rate under a regular heating mode makes it possible to resolve the issue related to the duration of control over the technical condition of a rolling bearing using a thermal method. Reducing the control procedure duration, when using the improved thermal non-destructive testing, by 4 times, would yield a reduction in operating costs due to the possibility of ongoing control over rolling bearings at the beginning of the equipment operation. It has also been confirmed that the heating rate of rolling bearings under a regular heating mode directly depends on their technical condition and does not depend on the load transferred and the mode of operation of the bearing nodes of the technological equipment. The proposed method could be applied in the maintenance system based on the actual condition of the equipment for the operative control over rolling bearings
