The invention relates to mechanics and can be used as a safety clutch or clutch in tyazhelogruzhennogo drives of different mechanisms.

Known cone friction clutch, which when moving cone coupling, a part of the cone in contact with the cone driven parts, allows the enabling and disabling mechanism on the go (1).

However, this device has significant drawbacks requires precision manufacture, has a relatively large radial dimensions per unit of transmitted torque.

Known friction clutch, located containing the NII layers wedge is cut rings and decompressing, presses against the case. To transfer a large torque in the design between the wedge ring and put the multiplier lever (2).

This coupling has the disadvantage of a relatively complicated device and the unreliability of the coupling due to the presence of a mechanical device decompresses and possible problems.

The technical effect of the invention is to improve reliability of the operation of the coupling, as well as simplifying its construction.

This effect is achieved by the fact that in a friction coupling comprising two coupling halves and split elastic ring mounted on the inner coupling half, the working surface of the ring is made conical with a cone angle equal to the angle of the cone facing toward the outer coupling.

In Fig. 1 shows a longitudinal section of the coupling; Fig. 2 section a-a in Fig. 1.

The coupling has a coupling 1 with a conical working surface 2 and the inner flexible coupling 3 installed on it, for example, by means of the tooth 4, the elastic split ring 5 having a conical working surface 6, the mating with the inclusion of working surface 2 coupling 1.

The clutch operates as follows.

the emergence of the conical working surfaces 2 coupling 1 and 6 of the ring 5. Arising between the working surfaces 2 and 6, the frictional force deforms the elastic ring 5, pushing him to the coupling half 1 thus the rotation of one coupling is transmitted to the other.

When disconnecting the coupling ring 5 due to the force of elasticity is returned to its original state.

the working surface of the ring cone, with the cone angle equal to the angle of the cone is coupled with outer coupling makes it possible to eliminate the mechanical decompresses the device, which greatly simplifies the design. The absence of mechanical decompresses the device allows to avoid possible mechanical problems, which increases the reliability of the design work.

A friction clutch comprising two coupling halves and split elastic ring mounted on the inner coupling, characterized in that the working surface of the ring is made conical with a cone angle equal to the angle of the cone facing toward the ring surface of the external coupling.

FIELD: machine engineering.

SUBSTANCE: method of engaging the braking is to apply a system of interconnection of the two shafts with unchanged reciprocal meshing gears. The brake clutch, which receives friction loads, is carried to the outer surface of the clutch housing. The system of interrelation of two shafts has an input shaft 1 and an output shaft 2. The wheel 3 is coaxially fixed to the output shaft. On the wheel along the circumference, the axles 4 are rotatably mounted. The gears 5 are fixed on the axes, having gearing with gear 6 on the input shaft 1. In parallel with the gears 5, the gears 7 are fixed on the axles 4. In the same plane with gears 7 coaxial to the axis of the input shaft is a brake gear 8 having a gearing with gears 7. The effect of the input shaft on the output is made by braking the brake gear 8 with the brake clutch 9. In the absence of braking, all the gears of the system rotate if the input shaft rotates. When braking the brake gear 8, the gears 7 are forced to roll around the perimeter of the brake gear 8. Together with the gears 7, the wheel 3 will rotate. The cylindrical part of the body 10 serves as a support for the brake gear and shaft 1. The brake gear 8 is connected to the conical gear 13. The conical gear 13 is toothed with a conical gear 14 fixed to the shaft 12. The shaft 12 extends beyond the housing 11 and is connected to the brake clutch 9. The brake clutch brakes the shaft 12 or leaves it in free rotation. When the shaft 12 stops, a torque is transmitted from the engine to the running gear shaft. If the shaft 12 is in free rotation, the engine is disconnected from the running gear.

EFFECT: placing the most vulnerable parts of the clutch in an accessible area for repair.
