Description

(54) МЕТЧИК(54) METER

таль попадает на гладкий калибрующий внутренний диаметр резьбы участок 2.Hoist falls on a smooth plotting internal thread diameter 2.

Исполнительный диаметр участка 2 выполнен несколько больше кшннмально допустимого размера внутреннего i диаметра резьбы , благодар  чему он приглаживает выступы на вершине резьбового профил  в детали, заполн   складкуI и оформл   внутренний дна метр получаемой рбзъбы. В дальнейшем обрабатываема деталь, пройд  через участок 2 попадает на вторую половину резьбовой калибрующей части 1, котора  поправл ет вершины резьбы.The executive diameter of section 2 is slightly larger than the allowable internal i size of the thread diameter, thanks to which it smoothes the protrusions on the top of the threaded profile in the part, fills the crease and the internal bottom of the meter is obtained. Subsequently, the workpiece, having passed through section 2, falls on the second half of the threaded gage part 1, which corrects the top of the thread.
