Description

Изобретение относитс  к металлообработке , а именно к изготовлению глобоидных передач. Известен способ нарезани  глобоидных черв ков в услови х обката и делени , при котором долб ку сообщают движение радиальной подачи дл  получени  требуемой высоты витков 1 Однако применение известного способа в случае, когда угол подъема витка черв ка превышает угол затыловани  зуба долб ка, приводит к возни новению неблагопри тных условий реза ни , по одной стороне витка, в резуль тате чего снижаетс  точность и чисто та нарезаемой поверхности. Целью изобретени   вл етс  повы шение точности и чистоты нарезаемой поверхности. Указанна  цель достигаетс  тем, что долб к устанавливают на глубину резани  и сообщгиот ему поступательное движение подачи вдоль его оси. На чертеже приведена схема относительного расположени  долб ка - и заготовки нарезаемого глобоидного черв ка. Долб ку 1, установленному на оси .стола на глубину резани , и обрабаты ваемому глобоид(ому черв ку 2, установленному на фрезерном шпинделе, сообщают согласованные вращательные движени  О)., и C(D.j. Долб ку, кроме того, сообщают поступательное движение подачи S вдоль его оси. При нарезании глобоидного черв ка косозубым долб ком согласование вращательных движе1Тий осуществл ют с помощью гитары делени  и дифференциала станка . При использовании пр мозубого долб ка дифференциал выключают, В случае, когда обработку производ т пр мозубым долб ком,, дл  получени  глобоидных черв ков с различным направлением спирали при одном и том же направлении вращени .ои измен ют направление вращени  Ct . .Пример. С помощью предлагаемого способа изготовлен глобоидный черв к с параметрами: -число заходов черв ка Z,3; -угол подъема спирали на делительной окружности в среднем сечении Т 9,612 ; -наружный диаметр заготовки в среднем сечении мм; направление спирали - правое.The invention relates to metal working, in particular to the manufacture of globoid gears. The known method of cutting globoid screws under the conditions of rolling and dividing, in which the radial feed movement is reported to the chisel to obtain the required height of the coils 1 adverse cut conditions, on one side of the coil, resulting in reduced accuracy and clean cut surface. The aim of the invention is to increase the accuracy and purity of the cut surface. This goal is achieved by setting the depth to the cutting depth and the forward movement of the feed along its axis. The drawing shows a diagram of the relative position of the dolby and the blanks of the chopped globoid screw. Dolby 1, installed on the axis of the table at the depth of cut, and machined globoid (threw the screw 2, mounted on the milling spindle, reported coordinated rotational motion O). S along its axis. When cutting a globoid worm with a helical teeth, the rotational movements are adjusted using a dividing guitar and a machine differential. When using a plunger, the differential is turned off. for obtaining globoid worms with different directions of the helix with the same direction of rotation. oo change the direction of rotation of Ct. Example. Using the proposed method, a globoid worm with parameters was made: - angle of the helix rise on the pitch circle in the middle section T 9.612; - outer diameter of the workpiece on the average section mm; the direction of the helix is right.

Дл  нарезани  использовалс  пр мозубый долб к с модулем ,5 мм, числом зубьев , углом затыловани  зуба (Ь 3° .For cutting, a hollow socket with a modulus, 5 mm, number of teeth, tooth tapering angle (L 3 °) was used.

Использование изобретени  позвол ет повысить точность и чистоту нарезаемой поверхности при изготовлении глобоидных черв ков с произвольным углом подъема спирали.The use of the invention allows to improve the accuracy and purity of the cut surface in the manufacture of globoid screws with an arbitrary angle of elevation of the spiral.
