Изобретение относитс к приборостроению и может быть применено в качестве приводного устройства в намоточных станках.This invention relates to instrumentation engineering and can be applied as a drive device in winding machines.

Известна двухскоростна волнова передача , содержаща корпус, внутри которого установлен механизм изменени числа оборотов ведомого вала и две ступени с гибким колесом и генератором, общим дл обеих ступеней , на корпусе генератора установлена торцова зубчата муфта, а механизм изменени числа оборотов выполнен в виде электромагнита , корь которого соединен со свободно вращающимс на ведомом валу передачи жестким колесом и имеет торцовые зубь , взаимодействующие под действием пружины с зубь ми полумуфты генератора 1.A two-speed wave transmission is known, comprising a housing, inside which a mechanism for changing the number of revolutions of the driven shaft and two stages with a flexible wheel and a generator common to both stages, is installed, an end gear coupling is installed on the generator case, and the mechanism for changing the number of revolutions is an electromagnet, measles which is connected to a rigid wheel freely rotating on the driven gear shaft and has end teeth interacting under the action of a spring with the teeth of the coupling half of the generator 1.

Однако при изменении направлени вращени ведущего вала измен ет направление вращени и ведомый вал, что не дает возможности применить эту передачу в намоточных станках.However, when the direction of rotation of the drive shaft is reversed, the direction of rotation and the output shaft change, which makes it impossible to apply this gear in the winding machine.

Ближайщим по технической сущности к изобретению вл етс волновой зубчатый редуктор , содержащий корпус, ведущий вал, жесткую и гибкую щестерни, генератор волновой деформации, ведомый вал и три механизма свободного хода 2.The closest in technical essence to the invention is a wave toothed gearbox, comprising a housing, a drive shaft, a rigid and flexible pinion, a wave deformation generator, a driven shaft, and three free wheeling mechanisms 2.

Два механизма свободного хода - механизмы одностороннего действи - установлены па ведущем валу и один из нпх св зан с генератором волновой деформации, а другой - с третьим механизмом свободного хода , установленным на ведомом валу, который выполнен в виде механизма одностороннего действи , противоположного по направлению вращени св занному с ним механизму свободного хода, установленному на ведущем валу, и соединен своей наружной обоймой сTwo free-wheeling mechanisms — one-way mechanisms — are installed on the drive shaft and one of them is connected with a wave strain generator, and the other with a third free-wheel mechanism mounted on the driven shaft, which is designed as a one-way mechanism opposite to the direction of rotation. its associated free-wheeling mechanism mounted on the drive shaft, and is connected with its outer race to

гибким колесом волновой передачи. В таком выполненни волновой зубчатый редуктор позвол ет обеспечить неизменное направленно вращени ведомого вала при реверсировании ведущего вала.flexible wave transfer wheel. In such a design, a wave gear reducer allows the directional rotation of the driven shaft to remain unchanged while the drive shaft is reversed.

Однако при вращспии ведущего вала п одном направленнн ведомый вал вращаетс со скоростью, обуславливаемой передаточным числом волнового редуктора, а при вращении ведущего вала в противоположном 1аправле-.However, when the drive shaft rotates in one directional, the drive shaft rotates at a speed determined by the gear ratio of the wave gearbox, and when the drive shaft rotates in the opposite direction.

иии ведомый вал хот и сохран ет направление вращени , но без участи волновой пере, дачи, т. е. со скоростью ведущего вала,This drive shaft, although it retains the direction of rotation, but without the fate of wave transmission, i.e., at the speed of the drive shaft,

Целью изобретени вл етс получение редуцироваиного однонаправленного вращени ведомого вала при реверсивном вращении ведущего вала.The aim of the invention is to obtain a reduced unidirectional rotation of the driven shaft when the driving shaft is reversing.

Claims

To do this, in the proposed wave gear reducer, the driven shaft is hollow, the reducer is equipped with an additional fourth free wheel mechanism and a fixed axis located inside the hollow driven shaft and rigidly connected to the body, the first mechanism is located between the hard gear and the body, and the second between the hard gear and the driven shaft, the third between the flexible gear and the fixed axle, and the fourth between the flexible gear and the driven shaft. FIG. 1 shows the proposed wave gear reducer, a longitudinal section; on phpg. 2 - a section on And - And on fpg. one; in fig. 3 - section along B - B pa fpg. one; in fig. 4 - a section on In - In on fpg. 1. The reducer consists of a split housing, which is a cylindrical cup I, fastened on one side with vnmi 2 with a cover 3 in which a wave deformation generator 5 is installed on bearings 4, and on the other side with a flange b in which bearings 7 installed hub 8, connected by screws 9 with a rigid gear gear 10 and key II to the free wheel 12. In the hub 8 bearings 13 and 14 have a hollow driven shaft 15 with free wheel mechanisms 16 and 17. pins and spider 18 ( gear, pulley n t. p.) on w 19. Inside, and a hollow driven shaft 15 on a bearing 20, a fixed axis 21 is placed with a free-wheeling mechanism 22 on a key 23, rigidly connected to the gearbox housing by means of a cylindrical cup 24 with windows along the periphery and an intermediate flange 25. Further, using bearings 26, a holder 27 is mounted on a fixed axle, rigidly fastened with screws 28 to a flange 29, which is connected with pins 30 to a flexible gear gear 31. The proposed gearbox works in the following manner. When clock wave generator 5 is rotated clockwise, freewheel 12 is wedged, hard gear teeth 10 stop, and gear teeth 31 begin to rotate in the direction opposite to the direction of rotation of wave strain generator 5, and the free wheel 16 is jammed and the vede rotates .my shaft 15 counterclockwise.
