Description

взаимодействующей с двум соосно расположенными на одном валу 11 коническими шестерн ми 12, между которыми расноложена двухсторонн зубчата муфта 13.11 conical gears 12 interacting with two coaxially arranged on the same shaft, between which there is a two-way gear coupling 13.

Станок работает следующим образом.The machine works as follows.

При возвратно-поступательном движении щпиндел 9 вместе с внутренним корпусом 8 реечна шестерн 3 перекатываетс по рейке 2, сообща через гитару смепных колес 6 и конические шестерни 10 и 12 дополнительное вращательное движение шпиндел 9. Дополнительное вращательное движение при сложении с возвратно-поступательным движением шпиндел 9 дает винтовое движение шпинделю. Одновременно с винтовым движением шпиндель 9 и механизм винтового движени 1 получают обкаточпое движение от черв чного колеса 5.During the reciprocating movement of the pin 9, together with the inner case 8, the pinion gear 3 rolls along the rail 2, together with the guitar of the mixing wheels 6 and bevel gears 10 and 12, the additional rotational movement of the spindle 9. The additional rotational movement when the spindle 9 is added gives screw movement to the spindle. At the same time as the screw movement, the spindle 9 and the screw movement mechanism 1 receive a rolling movement from the worm gear 5.

Сложение винтового и обкаточного движени позвол ет нарезать косозубые колеса по методу обкатки.The addition of the screw and break-in movement makes it possible to cut helical gears according to the running-in method.

Нарезание косозубых колес с различным направлением зубьев выполн ют путем переключени двухсторонней зубчатой муфты 13.The cutting of helical gears with different tooth directions is performed by switching the double-sided gear coupling 13.

Зубодолбежный станок имеет малые габариты и широкие технологические возмол ности .. На нем можно нарезать и пр мозубые , и косозубые колеса с различными направлением и углом наклона зубьев.The gear shaping machine has small dimensions and wide technological capabilities. It can cut both spur and helical gears with different directions and the angle of inclination of the teeth.

Дл переналадки станка не требуетс затрат времени.To change the machine does not require time-consuming.

Механизм винтового движени 1 зубодолбежного станка можно устанавливатьThe mechanism of the screw movement 1 gear shaping machine can be installed

на любом станке дл обработки деталей одного типоразмера.on any machine for machining parts of the same size.

Claims

1. Spindle gear for cutting cylindrical helical gears, in which the mechanism of the screw movement of the spindle includes a rack-and-gear

a gear associated with one of the elements of a worm gear pair driving the spindle into a rolling movement and a guitar of exchangeable wheels, characterized in that, in order to reduce the overall dimensions of the machine, the screw movement mechanism is installed in two horizontally arranged and installed one in another housings, and the outer casing is mounted on a screw wheel indicated

pairs and bears a rigidly fixed rail, and the inner case is on the machine spindle and contains a rack and pinion gear and a guitar of replaceable wheels.

2. The machine according to claim 1, characterized in that, in order to cut helical gears in the opposite direction, the machine is provided with a reverse mechanism, made in the form of a spindle mounted in the inner case of the bevel wheel,

interacting with two bevel gears coaxially located on the same shaft, between which there is a double-tooth gear coupling.
