Description

ki 4 clamped in the wells, can be adjusted by changing the magnitude of the deformation of the springs 5 with screws 12 placed in the lid 13 mounted for rotation on the shaft 2. On the tapered outer surface of the spring-loaded disk 3, made with an angle cci to the axis of the disk, there are balls 14, which are held by bevels on the surfaces of the disks 15 and 16 facing each other, the slots are connected to the internal slots of the housing 10 of the coupling. The disk 16 is pressure and is in contact with the package of the friction disks 9 and I. The axial movement of the stop disk 15 is carried out with the help of screws 17.

When the torque does not exceed the specified limit value, the clutch operates as follows.

Under the force of the springs 5, the balls 4 roll into the deeper parts of the wells of the spring-loaded disk 3 and the sleeve 6. In this case, part of the forces of the springs 5 is transferred to the conical outer surface of the spring-loaded disk 3 to the balls 14, which press the pressure disk 16 to the package of the friction disks 11 and 9. transmission of torque by the drive shaft 1 to the driven shaft 2.

As the torque increases above the limiting value, the balls 4 are pushed out of the wells (see fig. 2, where the angle is 2 is the angle of the holes) while pressing the spring-loaded disk 3, while the balls 14 do not create enough force to press the pressure disc 16, slipping of the friction discs 11 and 9 occurs. The clutch worked.

When the torque decreases, the balls 4 under the action of the force of the springs 5 return to the deeper parts of the wells, the spring-loaded disk 3 axially moves, the balls act on the pressure disk 16, which compresses the package of the friction disks.

The adjustment of the limit value of the torque transmitted by the coupling at a certain value of the angles KI and a2 is carried out with the help of SCREWS 12, which regulate the force of pressing the spring-loaded disk 3 to the bevels on the surfaces of the disks 15 and 16 and screws 17, displacing the disk 15.

Subject invention

A friction clutch contains concentrically mounted drive and driven half couplings connected by friction disks placed on their splines connected to a spring-loaded disk of the actuating device placed on the splines of the driven shaft and having on the end of the hole for rolling bodies, characterized in that reduce radial dimensions, increase sensitivity, increase the transmitted torque, the actuation device is equipped with pressure and stop disks sequentially mounted on the slave zero coupling and having bevels on facing each other, forming a cavity in which balls are in contact with them interacting with the outer surface of a spring-loaded disk made cone, and the stop disk is provided with a regulating element that mixes it to the disk that contacts friction discs. 15 1 IS 4I I I
