(5) КУЛАЧКОВАЯ ПРЕДОХРАНИТЕЛЬНАЯ МУФТА(5) CAM PROTECTION COUPLING

1one

Изобретение относитс к машиностроению и может быть использовано дл предохранени узлов машин и механизмов от поломок при перегрузке рабочего органа.The invention relates to mechanical engineering and can be used to protect the components of machines and mechanisms from breakdowns when the working body is overloaded.

Известна кулачкова предохранительна муфта, содержаща две полумуфты , соединенные кулачками, выполненными на торцах полумуфт, подпружиненных цилиндрическими Лружина- Q ми р J.Known cam safety clutch, containing two coupling halves, connected by cams, made on the ends of the coupling halves, spring-loaded cylindrical Llyuzhina- Q m p J.

Однако така муфта имеет низкую долговечность в силу быстрого износа поверхности кулачков, срабатывание муфты сопровождаетс большим шумом. )5However, this clutch has low durability due to the rapid wear of the cam surface, the clutch actuation is accompanied by a lot of noise. )five

Известна кулачкова предохранительна муфта, содержаща две полумуфты , соединенные промежуточным звеном с торцовыми кулачками, выполненными на поверхности тарельчатых пру- 20 жин, жестко закрепленных на полумуфтах L lОднако возможности известной муфты ограничены, так как в силу жесткого креплени тарельчатых пружин с двум кулачками на полумуфтах она не обладает компенсирующими свойствами , передает крут щий момент строго определенной величины.Known cam clutch, containing two coupling halves, connected by an intermediate link with end cams, made on the surface of cup-shaped springs 20, rigidly fixed on the coupling half. does not possess compensating properties, transmits the torque of a strictly defined value.

Цель изобретени - расширение эксплуатационных возможностей.The purpose of the invention is the expansion of operational capabilities.

Поставленна цель достигаетс тем, что в кулачковой предохранительной муфте, содержащей две полумуфты, соединенные промежуточным звеном с торцовыми кулачками, промежуточное звено выполнено в виде двух шайб с гофрами, кажда из которых смонтирована на соответствующей полумуфте и подпружинена относительно нее в осевом направлении , при этом выступы одной из шайб размещены во впадинах другой шайбы.The goal is achieved by the fact that in a cam clutch containing two coupling halves connected by an intermediate link with face cams, the intermediate link is made in the form of two washers with corrugations, each of which is mounted on a corresponding coupling half and is spring-loaded relative to it in the axial direction, while the projections one of the washers are placed in the hollows of the other washer.

На фиг. 1 изображена кулачкова предохранительна муфта, общий вид; на фиг. 2 - вид А на фиг. 1.FIG. 1 shows a cam clutch, general view; in fig. 2 is a view A of FIG. one.

Claims

The cam clutch contains two half couplings I and 2, connected by end cams 3 formed by wave-forming corrugations of elastic washers i fixed on the ends of half couplings 1 and 2 with fingers 5. On which between ends of half couplings 1 and 2 and elastic washers there are springs 6. Washers 7 8 and the metal sleeve 9 protects the coupling against rapid wear. The coupling works as follows. The torque from the leading, for example, coupling half 1 is transmitted to the driven coupling half 2 through the fingers 5 to the cams 3 washer k of the driving coupling half. In the event of overloading, the driving gear for the coupling 2 is braked, the spring is compressed, 6 bypasses the washer of the driven half of coupling 2, the corresponding cams 3 get out of engagement, and slip one by one over the other. When the overload is removed, the coupling half is automatically cordoned off, and the mechanism continues to operate. The clutch is easy to manufacture and operate, smoothes the starting torque and compensates for the angular and axial displacements of the connected shafts, allows you to work in reversing mode. The invention of the Kulachkov safety clutch, comprising two coupling halves, interconnected by an intermediate link with face cams, characterized in that, in order to enhance operational capabilities, the intermediate link is made in the form of two pucks with corrugations, each of which is mounted on a corresponding coupling half and spring loaded relative to it in the axial direction, with the protrusions of one of the washers placed in the hollows of the other washer.
