Diagnostics of stabilization modes of shape strand ropes

Abstract

The work is devoted to the diagnostic issues of the possibilities of technological balancing of steel shaped strand ropes of lifting and transport equipment, which is of great scientific and practical importance, since it will improve their performance. A literature review showed that this topic is practically not covered and only the issues of straightening (bending) strands, which are not effective enough, are considered. The research objective and the problem that must be solved to obtain ropes with better quality characteristics (greater durability and strength) have been formulated. A more accurate expression for the technological torque of shaped strands is presented. The ways of reducing the torque as a harmful factor are indicated. Diagnostics of possible options for technological balancing of ropes was carried out. Rational modes of manufacturing shaped strand ropes have been determined.

Diagnostics of an innovative repair kit for transport equipment units

“…The following technical requirements are imposed on the cardan shaft crosspieces that are being repaired. The crosspieces are not accepted for repair in the presence of one of the following defects [6,7,9] cracks; discoloration; ovality and taper over 1 mm; when the spikes are worn more than 1.3 mm in diameter. The tribo-coupling shown in Figure 1 consists of a shaft 1, an outer ring 2 and a special insert 3 made in the form of a spiral coil spring placed between the shaft and the outer ring.…”
