Description

II

Изобретение относитс  к маи тостроению а именно к резьбовым соединени м типа шпилька-корпус .FIELD OF THE INVENTION The invention relates to engineering, namely, threaded connections of the type stud-body.

Известно коническо-цилиндрическое резьбовое соединение, в котором неподвижность и герметичность резьбового соединени  создаетс  за счет свинчивани  наружной конической резьбы и цилиндрической внутренней резьбы до определенного крут щего момента 1. Такие соединени  примен ютс  дл  штуцеров, тройников и т. д. Дл  установки шпилек в корпуса они не примен ютс , так как в этом случае имел бы . место слишком большой перепад завернутых шпилек по высоте.A conical-cylindrical threaded joint is known in which the immobility and tightness of the threaded joint is created by screwing an external conical thread and a cylindrical internal thread to a specific torque 1. These connections are used for fittings, tees, etc. they are not applicable, as in this case they would. the place is too big drop wrapped studs in height.

Наиболее близким по технической сущности к изобретению  вл етс  резьбовое соединение с гарантированным иат гом, содержащее шпильку и корпус 2,The closest in technical essence to the invention is a threaded connection with a guaranteed iatom containing a pin and a body 2,

К недостаткам известного резьбового соединени  относ тс  высокие требовани  к точности изготовлени , нестабильность момента стопорени  и невозможность использовани  надежного антикоррозионного покрыти .The disadvantages of the known threaded connection are high demands on the accuracy of manufacture, the instability of the moment of locking and the inability to use a reliable anti-corrosion coating.

Дл  повышени  надежности стопорени  и повышени  технологичности изготовлени  резьб , резьба шпильки выполнена с конусом 2-3°, а отверстие в корпусе - цилиндрическим, при этом гарантированный нат г выполнен по среднему диаметру резьбы на. участке со стороны ее сбега.To increase the reliability of locking and improve the manufacturability of threads, the stud thread is made with a 2-3 ° cone, and the hole in the body is cylindrical, while guaranteed tension is made according to the average thread diameter. plot from her sbeg.

На фиг. 1 изображено предлагаемое резьбовое соединение шпилька-корпус общий вид; на фиг.2 дана схема расположени  полей допусков среднего дааметра резьб шпильки и отверсти  в сечени х А-А и Б-jB на фиг. 1.FIG. 1 shows the proposed threaded connection stud-body general view; Figure 2 shows the layout of the tolerance fields of the average diameter of the threads of the studs and the holes in sections A-A and B-jB in FIG. one.

На чертеже прин ты следующие обозначени :In the drawing, the following notation is used:

1 - шпилька, 2 - корпус;1 - stud, 2 - body;

С - длина сбега шпильки;C - length of the sprint;

L - длина свинчиваии ; лр/2 - половина угла конусности резьбы шпиль- ,L is the length of screwing; lr / 2 - half angle of the taper of the thread

ки;ki;

минимальный (гарантированный) зазор в конце длины свинчивани . minimum (guaranteed) clearance at the end of the make-up length.

Резьбовое соединение шпи;гьки 1 и корпуса 2 обеспечиваетс  нат гом по сбегу и нат гом по среднему диаметру в зоне, прилегающей к сбегу. Величина угла конуса резьбы шпилькиThe threaded joint of the spike; the nuts 1 and the body 2 are tensioned along the escape and tension along the mean diameter in the zone adjacent to the escapement. The angle of the thread cone studs
