где параметры конической резьбы:
P - шаг резьбы;
φ - угол уклона;
l* - длина конической резьбы до основной плоскости - определены стандартом;
n - число пазов,
δm - величина износа резьбы по среднему диаметру, статистически средняя для конических резьб, подлежащих восстановлению;
l - текущая координата вдоль образующей резьбы с началом отсчета в середине образующей.1. A tool for restoring tapered threads of oilfield pipes, containing a working surface in the form of a threaded element, a response to the machined thread, with grooves located on the working surface and intersecting the thread direction, with a reinforcing wear-resistant coating applied to the working surface, characterized in that the coating is applied stripes along the grooves on the front, rear contact surfaces of the thread, on its tops and troughs, the width of the stripes is at least 2 mm from the groove, while the coating strip is made along the edge at least on one side of each groove corresponding to the location of the entries in the thread when making up the tool with a mating thread element, and the coating thickness is given by
where the conical thread parameters are:
P is the thread pitch;
φ is the slope angle;
l * - the length of the tapered thread to the main plane - defined by the standard;
n is the number of grooves,
δ m - the value of thread wear along the average diameter, statistically average for tapered threads to be restored;
l is the current coordinate along the generatrix of the thread with the origin in the middle of the generatrix.
