Abstract

Currently, there are practically no sufficiently satisfactory analytical methods for predicting the reliability of newly designed machines. Basically, the task is solved on the basis of information obtained largely during resource bench tests of parts, assemblies and aggregates. The stands used for carrying out resource tests of machine transmissions can be divided according to the type of loading into open loading stands and closed loading stands. Open loading stands are driven by an AC or DC electric motor and are decelerated by a special braking system. Closed loading stands load the transmission without the use of braking systems. This article discusses the physical features of the operation of stands with a closed power flow used for testing V-belt gears, which can significantly reduce energy costs. The analysis of the application of an analytical method for predicting the reliability of newly designed machines is carried out on the basis of information obtained largely during resource bench tests of parts, assemblies and aggregates.
