Abstract

Изобретение относитс к области машиностроени и может найти применение дл преобразовани непрерывного вращени в прерывистое. Целью изобретени вл етс повышение надежности и точности фиксации. При вращении барабана 3, когда один из роликов 9 или 10 находитс в переходном пазу 6, происходит поворот на заданный угол ведомого диска 1. Когда ролики 9, 10 поступают в пазы 4, 5 происходит остановка ведомого диска 1. После этого при вращении барабана 3 ролик 9 выходит из пазов барабана 3, а очередной ролик ведомого диска 1 входит в паз барабана 3. По мере износа рабочих поверхностей роликов и пазов барабана 3, ось 7 вращени которого предварительно установлена под углом к линии 8, осуществл етс поворот барабана 3 относительно оси 11, при этом рабочие поверхности роликов начинают контактировать не с наружными рабочими поверхност ми пазов 4 и 5, а с их внутренними рабочими поверхност ми. При этом выбираютс образовавшиес зазоры между рабочими поверхност ми роликов и пазов. 2 ил.The invention relates to the field of mechanical engineering and can be used to convert continuous rotation into intermittent. The aim of the invention is to increase the reliability and accuracy of fixation. When the drum 3 is rotated, when one of the rollers 9 or 10 is in the transition groove 6, the slave disk 1 rotates to a predetermined angle. When the rollers 9, 10 enter the grooves 4, 5 the slave disk 1 stops. After that, when the drum 3 rotates roller 9 emerges from the grooves of the drum 3, and the next roller of the driven disc 1 enters the groove of the drum 3. As the working surfaces of the rollers and the grooves of the drum 3 wear, the axis of rotation 7 of which is preset at an angle to the line 8, the drum 3 rotates about the axis 11, while working surface rollers begin to not contact the outer working surfaces of the grooves 4 and 5, and with their internal working surfaces. In so doing, the gaps between the working surfaces of the rollers and the slots are selected. 2 Il.

Claims

The mechanism for converting continuous rotation into intermittent, containing a leading cam in the form of a drum with two parallel grooves and a transition groove made in a helical line with a variable pitch, and a driven disk with rollers radially mounted on the end surface, interacting with the walls of the grooves of the drum, o which means that. in order to increase the reliability and accuracy of fixation, the axis of the drum is located at an angle to the line passing through the centers of two adjacent and interacting with the walls of the grooves of the rollers, and the drum is mounted with the possibility of rotation relative to the axis passing through the middle of the straight line connecting the centers of the said rollers and perpendicular to the plane of the end surface of the driven disk.
