Description

The invention relates to mechanical engineering and can be used in waters and mechanisms where it is necessary to convert the rotational movement into a transmission with a large gear ratio and the ability to switch to accelerated mixing, for example, on metal-cutting machines.

The purpose of the invention is to extend the kinematic capabilities of a geared drive by: abnding with a device in the form of a cam clutch, which provides an additional speed of movement of the worm wheel.

The drawing shows a kinematic diagram of a worm gear.

The worm gear contains two shafts 1 and 2 parallel to each other, rigidly connected respectively with worm 1 and 3 and 4, mounted in supports 5.

With screws 3 and 4, the worm gear 6 is engaged, which has the ability to move along the axis of the screws. An additional worm gear 7, a cam clutch 8 and a gear wheel 9, which also has the ability to rotate on the shaft 1, are installed on the shaft 1 with a wrench:; brains; 1): epod1i: an additional 1: e} in an inventive number. - from 10 and a cogwheel P.

wheels 7 and 10. If the cam sleeve 8 is connected to the additional worm gear 7, then worms 3 and 4 will rotate in different directions at different speeds. At the same time, the worm gear Ko; i.eco 6 will move along the axes of the worm 3 and 4 in one direction or the other depending on the direction of rotation of the additional worm 1Z, and the speed of the displacement of the wheel b will be less, than the smaller the difference in diameters of additional worm wheels 7 and 10. If accelerated movement of the worm wheel 6 is required, then the cam one. The 1ht 8 is switched to the gear train. As a result, the screws 3 and 4 rotate in the same direction at the same speed, and the worm gear 5 will move along; c) into the 3 n hour at the accelerated speed.
