Другим условием перемещением детали 2, с точки зрени обеспечени ее гарантированно безотрывного обкатывани поверхности а трубы 1, вл етс соблюдение неравенства:Another condition for the movement of the part 2, from the point of view of ensuring its guaranteed continuous rolling-in of the surface a of the pipe 1, is the following inequality:
di d + 1, мм(8)di d + 1, mm (8)
d2 d + S, мм,(9) где d - диаметр детали 2,. мм;d2 d + S, mm, (9) where d is the diameter of part 2 ,. mm;
di - нижний внутренний диаметр трубы 1, мм;di is the lower inner diameter of the pipe 1, mm;
d2 - верхний внутренний диаметр трубы i, мм.d2 is the upper inner diameter of the pipe i, mm.
На основании неравенства (8) и (9) следует , что угол конуса поверхности а должен удовлетвор ть условию:Based on inequality (8) and (9), it follows that the cone angle of the surface a must satisfy the condition:
d2-di d2-di
Ti--tg2 TTi - tg2 T
где I - длина трубы, мм.where I is the length of the pipe, mm
Неравенства (7) и (10) объедин ютс в двойное неравенство:Inequalities (7) and (10) are combined into a double inequality:
Из неравенства (11) следует, что дл обеспечени увеличени рассто ни перемещени деталей, т. е. дл обеспечени возможности увеличени длины трубы, необходимо обеспечить уменьшение коэффициента трени .From inequality (11) it follows that in order to provide an increase in the distance of movement of parts, i.e., to provide the possibility of increasing the length of the pipe, it is necessary to reduce the friction coefficient.
Уменьшение коэффициента трени между перемещаемыми детал ми и внутренней поверхностью трубы может быть обеспечено путем покрыти этой поверхности антифрикционным материалом или пу . /A reduction in the coefficient of friction between the moving parts and the inner surface of the pipe can be achieved by coating this surface with antifriction material or PU. /
тем введени в сжатый воздух микрочастиц смазки.thereby introducing lubricant microparticles into the compressed air.
Таким образом,, предлагаемый способ позвол ет перемещать цилиндрические де- 5 тали на рассто ни , достаточные дл использовани этого способа дл межоперационного перемещени , например , собираемых деталей в сборочных автоматах ..Thus, the proposed method allows the cylindrical parts to be moved to a distance sufficient to use this method for interoperative movement of, for example, assembled parts in assembly machines.
10 Предлагаемый способ целесообразно использовать в сборочных автоматах, процесс сборки в которых осуществл етс пневмовихревыми ориентаторами. Это позволит повысить уровень унификации тех15 ники..10 The proposed method is expediently used in assembly machines in which the assembly process is carried out by air-vortex orientators. This will increase the level of technical unification.
