(54) СЦЕПНАЯ КУЛАЧКОВАЯ МУФТА(54) COUPLER CAM COUPLING

1one

Изобретение относитс к машиностроению ,и может быть использовано дл передачи вращени в услови х повышенных требований по люфту, а также дл стопорени и фиксации поворотных элементов.The invention relates to mechanical engineering, and can be used for transmitting rotation under conditions of increased backlash requirements, as well as for locking and fixing rotating elements.

Известна сцепна кулачкова муфта, содержаща ведомую и ведущую полумуфты, взаимодействующие посредством торцовых кулаздсов, при зтом полумуфты установлены на валу посредством шпоночного соединени 1.A known coupler cam coupling, comprising a driven and a leading coupling half, interacting by means of end faces, while this coupling half is mounted on the shaft by means of a keyed joint 1.

Недостатком муфты вл етс невозможность точных.передач из-за люфта в шпоночном соёданешга.The disadvantage of the coupling is the impossibility of accurate transmissions due to play in the keyway.

Щль изобретени - повышение надежности за счет исключени люфта.The invention is to increase reliability by eliminating backlash.

Эта цель достигаетс тем, что сцепна кулачкова муфта, содержаща ведущую и ведомую полумуфты с торцовыми кулачками, снабжена охватьтающей ведомзто полумуфту подвижной в осевом направлении дополнительной полумуфтой с торцовьши кулачками, контактир5аощими с кулачками ведущей и ведомой полумуфт, при зтом ведуща и ведома полумуфты жестко закреплены на соедин емых валах, а кулачки на этих полумуфтах установлены на поверх (юст х, обращенных к ведомому валу.This object is achieved in that Coupling jaw clutch comprising driving and driven half coupling with the end cams provided ohvattayuschey vedomzto coupling half axially movable additional coupling half with tortsovshi cams kontaktir5aoschimi cams driving and driven coupling halves at ztom driving and driven coupling half is rigidly fixed to connecting shafts, and the cams on these coupling halves are mounted on top of (coupling arms facing the driven shaft).

При этом ведуща полумуфта может быть установлена концентрично ведомой.In this case, the leading coupling half can be set concentric driven.

На фиг. 1 изображена муфта, общий вид; на фиг. 2 - вариант выполнени муфты с концентрично установленной ведомой.FIG. 1 shows the coupling, general view; in fig. 2 shows an embodiment of a coupling with a concentrically mounted slave.

На ведущем валу 1 неподвижно установлена ведуща ползтиуфта 2 с торцовыми кулачками 3. На соосном с валом 1 ведомом валу 4 On the driving shaft 1, the fixed crawler 2 with face cams 3 is fixedly mounted. On the shaft 4 driven coaxially with the shaft 1

10 неподвижно установлена ведома полумуфта 5 с торцовыми кулачками 6. Кулачки на обеих полумуфтах обращены в одну сторону, в сторону ведомого вала 4. На ведущем валу 4 с возможностью управл емого осевого перемеIS щени установлена дополнительна промежуточна полумуфта 7 с кулачками 8 и 9. Ведуща полумуфта 2 установлена концентрично ведомой полумуфте 5. Кулачки 6 расположены в одной плоскости с кулачками 3, вл сь их 10 fixedly installed driven half coupling 5 with face cams 6. The cams on both coupling half are turned in one direction, towards the driven shaft 4. On the drive shaft 4 with the possibility of controlled axial movement, an additional intermediate half coupling 7 with cams 8 and 9 is installed. 2 is mounted concentrically with the driven half coupling 5. The cams 6 are located in the same plane with the cams 3, they are

30 продолжением, а длина кулачков 10 соответствует суммарной длине кулачков 3 и 6.30 is continued, and the length of the cams 10 corresponds to the total length of cams 3 and 6.

Claims

For connection, the drive shaft 1 with the driven shaft 4 an additional intermediate coupling half 7 moves towards the coupling halves 2 and 5. The cams 8 and 9 of the additional intermediate coupling half 7 engage with the cams 6 and 3 of the coupling half 5 and 2. Through the additional intermediate coupling half 7, coupling halves 2 and 5 are connected, and thus the backlash-free connection of shafts 1 and 4. Such a design of the coupling allows to eliminate the backlash in the coupling of the half-coupling to the shaft and jnvieHbnmTb the backlash in the transmission, and in case of using the coupling as a stopper The xiruyushchy element provides bepuyftovy fixing. Claim 1. Coupling cam clutch, which contains the leading and driven coupling halves with face cams, characterized in that, in order to increase reliability by eliminating backlash, it is provided with an additional coupling half moving axially in the axial direction, coupled with the cams, contacting with the cams the leading and driven half coupling, while the leading and driven coupling half are rigidly fixed on the connecting shafts, and the cams on these coupling half are installed on the surfaces facing the driven shaft.

2. Clutch according to claim 1, characterized in that the leading clutch clutch is mounted concentrically in the home. Sources of information taken into account in the examination 1. V. V. Polkov, I.
