Abstract
Screw operating members have been widely applied in all branches of the national economy thanks to the combination of different operations while transporting. Specific feature of their operation is caused by the variety of the production processes operations, as well as the regional characteristics of the transported materials, designation and design parameters of screw mechanisms. Original welded construction of the screw sectional operating member of small material consumption, high maneuverability and improved operation reliability and durability has been proposed. The operation of the screw operating member is as follows. During rotation of the spiral section the rotary motion is transmitted through the running body to the spherical rod and neighboring sections of the screw operating member. The advantages of the operating member are those, that while adjusting of this unit complicated technological equipment is not needed. All equipment is normalized and provides proper maintenance and replacement. At the stage of technical project the construction and its adjusting units, are created, the design shape of all parts, loading devices, operating member, itc is determined. The proper choice of the spiral surface shape prevents the appearance and creation of so-called “dead area”, which can occur while gripping and transporting of materials. At this stage the problems of production effectiveness of methods for producing blanks, in the case when they are used for winding of the profile-shaped spirals in particular, are solved. Besides, the choice of technological process for parts working, the adjustment of units and it self are carried out. Production effectiveness of the unit design mastering must result in the raise of labor efficiency, reduction of expenses and shortening of time for designing, technological preparation of production, manufacturing, maintenance and repair of the product providing its high quality.
