“…where: Pi -circumferential force on the gear wheel of the planetary gearbox; r -gear radius; lshoulder; Ԛ -the total force applied to the shoulder l (the weight of the gearbox and the load). From the physical meaning of the occurrence of a load in a closed loop, it follows that the power consumed by the stand from the motor 4 (Figure 1) is spent on overcoming the friction resistance in preloaded kinematic pairs, therefore much less than the apparent power circulating in a closed loop [4]. The total power circulating along the contour consists of the apparent N1 and the power N2 expended by the engine to overcome the friction forces:…”

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.
