Abstract

The invention relates to mechanical engineering and can be used to protect the drives of mechanisms from overloading and destruction. The purpose of the invention is to reduce the dynamic oscillations when the clutch operates. This is ensured by carrying out at the ends in coaxially arranged and pressed together coupling halves 1, 2 and the pressure disk 3 ring tracks 8.9 with eccentricities 1, 1, relative to the axis of the coupling. When the nominal torque is transmitted, the half coupling 1,2 and the disk 3 are connected by balls 7 located in lanes 8.9. When reloading, the balls 7, not passing the moment, roll along the tracks 8.9, causing axial displacements of the coupling half 2 and the disk 3, which are small compared to lime 1 clutches. 2 ill.

Description

The invention relates to hardware and can be used for protection, for driving mechanisms against overloads and destruction.

The purpose of the invention is to reduce dynamic oscillations when triggered.

Figure 1 shows the clutch, a General view; figure 2 - section A-Anafig.1.

The clutch contains the leading coupling half 1, the driven coupling half 2, the pressure disk 3, pressed against each other by a spring 4 installed with an emphasis in the sleeve 5, a nut 6. The coupling half I and 2,

the disk 3 is connected by balls 7; the 15 are balanced by muffled in ring tracks 8 and 9 with a smooth bottom, mirrored on the ends of coupling half and 1 of disk 3 facing each other, while the track 8 is made relative to the axis of the coupling with eccentricity 1 , and track 9 - with eccentricity Ij. The V-Ma half-coupling 2 is installed on the leading coupling half I freely, and the pressure disk 3 is capable of axial movement.

The clutch works as follows.

The rotation with the leading coupling half 1 is transmitted as a result of the interaction of the balls 7 with the eccentricity walls, tracks 8 and 9 to the driven coupling half 2. When overloaded, brake the coupling half 2, tracks 8 and 9, respectively, half coupling I to 2 are displaced one relative to another, causing movement along a smooth road kam balls 7, with the subsequent

Invention Formula Safety ball coupling, containing coaxially arranged and pushed to each other leading and driven coupling halves and a pressure disk, interconnected by rolling bodies, located in the annular tracks, mirrored on the facing ends of each other of the coupling halves and the pressure disk, - so that, in order to reduce the dynamic oscillations when triggered, at the ends of the coupling halves and the pressure disk, additional annular tracks are installed, in which additional rolling bodies are installed, all the tracks are Nena with a smooth bottom and disposed eccentrically relative to one another and the axis of the clutch. the ball tends to push the previous one in the direction of rotation from the corresponding track to the end, which leads to axial displacement of the coupling half 2, disc 3 and preload of the spring 4. However, the axial displacements are insignificant, because due to the closure of the tracks and small eccentricities 1, Ij balls 7, not output at the end, rolls along tracks 8 and 9. At the same time, there is an additional track and a mirror-like performance of tracks at the ends of the coupling halves and a disk. provides a balance of mu you are relative to the axis Invention Formula Safety ball coupling, containing coaxially arranged and pushed to each other leading and driven coupling halves and a pressure disk, interconnected by rolling bodies, located in the annular tracks, mirrored on the facing ends of each other of the coupling halves and the pressure disk, - so that, in order to reduce the dynamic oscillations when triggered, at the ends of the coupling halves and the pressure disk, additional annular tracks are installed, in which additional rolling bodies are installed, all the tracks are Nena with a smooth bottom and disposed eccentrically relative to one another and the axis of the clutch.
