  • About the organization of traffic conditions of bridge cranes for a circle

    The article describes the main principles of the movement around the circumference of the cranes circular steps. It is proved that the defining characteristics of the organization of the movement of the crane on the circle are the geometric parameters of the mutual reversal of the running wheels of the crane, not the observance of the reversal determines the transverse slippage of wheels of the crane, and the shape of the wheels depends only on the elastic longitudinal slide. The result of slides and slippage is firing the head of the rail with one hand and the loss of stability when moving the crane. Stability stability ensures the achievement of the precision targeting of the gripping device. These parameters are the main performance characteristics that should be valued in absolute terms should be minimal.

    Keywords: nuclear power station, crane circular steps, suspension bridge crane, suspension wheel, cylindrical wheel, bevel wheel, the mutual reversal of wheels

  • Calibration of machines with numerical program control by means of a laser tracker of VINTAG

    Results of the performed works at calibration of the metal-cutting machine are given in article. The technology of performance of control is considered. The conclusion in which it is noted that laser trackers including the measuring Vintag vehicle produced by Faro firm, possess high efficiency of the solution of problems of calibration is made. Their software has an opportunity to carry out processing of results of measurements and preparation of reports directly on the platform of performance of work and to give results on the place. To provide the accuracy of measurements of the spatial coordinates of 0.005-0.01 mm at distances to 10000-15000 mm. All these characteristics allow to recommend to machine-building enterprises use of such and similar measuring cars for the solution of problems of calibration of metal-cutting machines.

  • Monitoring of geometrical parameters of running wheels of the polar crane

    the article presents the study in the control of the geometric parameters of wheels of cranes circular steps. The options considered to determine the radii of the wheels by indirect methods, of which the most effective are those based on the construction of the measuring triangle at the open part of the forming. As the final results and proposals noted the following: both control provide almost ravnovesnye results definitions of the geometric parameters of the wheels; more universal is the way to control the radius of the wheel, using calipers and this method is recommended when addressing these and similar problems.

    Keywords: Running wheels, geometrical parameters of wheels, crane of circular action, wheel radius, wheel cone corner

  • Technical control during the installation of technological equipment

    In the article mounting a production system. The analysis of the structure of the mounting system of production is determined that an integral part of it is a collection of elements - technical control. This collection of elements is divided into two groups. The first belongs to the module technical design, which developed simultaneously with the mounting technology basic principles on the use and parameters of the control technology. The second one is implemented in the module production management and is related to metrological assurance (quality management) installation process. Describes the group of elements of technical control are interdependent, have diverse relationships with each other and with other elements of the system and Assembly production.
