The issues of assembly of threaded connections are considered. Rarely percussive nut wrenches are presented as the tooling, which provide transfer of the maximum part of the flywheel energy to the anvil. The possibility of such transmission is realized due to the proposed selection of rational kinematic and inertial-metric parameters of the main elements of rarely percussive nut wrenches.

The physical criteria limiting the size of the channels, including the conditions excluding the fl ow of the medium between adjacent cameras "under the satellite", are considered. The comparison of the variants of the channels execution is carried out: in the end wall of the epicycle; in the end wall of the sun gear; in the cylindrical toothed surface of the sun gear. The design criteria that characterize the relative sizes of the channels have been refi ned. For any planetary rotary machines with the number of waves N of the epicycle, which exceeds the number of waves M of the sun gear by two (N – M = 2), the channels should be located at the ends of the epicycle, but with N – M = 1, the relative cross-sections of the channels in the cylindrical toothed surface of the sun gear are much larger than in the end wall of the epicycle, therefore, for a planetary rotary machines with a low pressure of the medium, for example, vacuum pumps, it is advisable to make the channels in the cylindrical toothed surface of the sun gear.

The dependence of the vortex motion of particles in the deposition process on the crystal structure and properties of the obtained substance is found. The possibility of creating a condensed environment with vortex quantum fl ows of particles moving without scattering of energy along equipotential surfaces of the medium in the form of similar phenomena (super low friction, superconductivity, superfl uidity, crystal growth in a vacuum) is established. A crystal growth model is proposed for the application of coatings.

The concepts of the accuracy of evaluating the parameters of roughness, an integral part of quality control of products, are analyzed. Measurements of roughness parameters do not allow obtaining their true values. For this, along with the obtained measurement result, it is necessary to indicate the measurement error. Uncertainty is investigated, which, in contrast to the error, has a progressive nature and is used as an assessment of the reliability of measurement results. By introducing measurement uncertainty into the calibration of a device for measuring roughness, it is possible to increase the measurement accuracy, and as a result, improve the performance of products. The main provisions of the proposed study can be taken as the basis for the development of metrological recommendations for factory laboratories.

This article is devoted to the issues of restoring the performance of fi re pressure hoses in a fi re when punctures, cuts and fi stulas occur. Failure of fi re pressure hoses in a fi re occurs due to mechanical damage during the laying of main and working lines. In this case, an increase in the working pressure in the bag system leads to the loss of extinguishing agents and the appearance of fi stulas, longitudinal and transverse breaks. This article offers a technical solution aimed at developing a new clamp design to restore the performance of a fi re pressure hose with a diameter of 55 mm when it is damaged: a puncture or cut. For this purpose, a three-dimensional model of the clamp was developed and its strength analysis was performed using the Autodesk Inventor computer-aided design system. This device will allow you to restore the supply of fi re extinguishing agents in the shortest possible time if the pressure hoses are damaged in a fi re.

The relationship between the tribotechnical failures in worm gears and the growth of dynamic loads is shown. The nonlinearity of the growth of the wear intensity over time is revealed. An exponential dependence of wear on time is proposed, taking into account the growth of the dynamic coeffi cient. A probabilistic assessment of the worm gear life was made, taking into account the exponential dependence of wear on time, when using different compositions of lubricants.
