Towards the Analysis of Dynamic Properties of a Parallel Structure Robot with Constant Output Link Orientation DOI: 10.22184/2499-9407.2024.35.2.76.80
The mechanism of parallel structure of a robot is considered, which is designed to realise translational movements of the output link used in various technological systems. The kinematic structure providing the specified motions contains a linear drive and two Hooke joints (cardan joint, universal joint) in each kinematic chain, which makes it possible to exclude all rotational motions. The problem of dynamic analysis of the said mechanism is solved when only one coordinate motion is required.

Geometry of Contact and Technological Aspects of Relieving of Gear Cutting Worm Hobs. Part 2. Determination of the Parameters of the Axial Profile of the Grinding Wheel When Relieving DOI: 10.22184/2499-9407.2024.35.2.60.69
The technological aspects of the process of grinding the side surfaces of the teeth of a gear-cutting worm hob are considered, such as: profiling of the grinding wheel and ensuring the processing of the full profile of the surface to be ground. The functional dependences of the calculation of the axial profiles of the working surfaces of the grinding wheel for processing each of the sides of the teeth of a gear-cutting worm hob are determined, depending on the setting of the angle of inclination of the axis of grinding wheel. The conditions for excluding underprofiling of the ground surface of the teeth are determined.

The Organisation of Maintenance and Repair of Machine-Tool Park of the Enterprise in the Format “By Technical Condition” DOI: 10.22184/2499-9407.2024.35.2.70.74
The transition methodology from maintenance and repair “according to regulations” to maintenance and repair “according to technical condition” (TC) is proposed. The development of a set of national standards related to the functioning of the TC system for development of the normative-technical base of the transition is considered.
