With the known chain drives, especially the

43W4. afm QffMMmmen ιιβττβητηβοβη, specials, steplessly adjustable, in which the force is transmitted through friction, only relatively small forces can be transmitted because the chains only rest on the driving and driven pulleys at a few points. In addition, there are friction losses when the chains run in and out »

In the below-described transmission, the power "absorbed feile a chain or a belt with her whole are doing on the discs to · Ber traction" wipe on. Power-transmission chain parts and the discs SetAt only ei% when look feile the kraftttbertragenden the chain of movement Have disks connected * If the chain runs out of the disks, the frictional connection is also lifted.

me Sj> travel of the chain takes place in Hg · 2) by balls? _e that support each other. When the chain runs up, these balls push pans apart, which are pulled together by a spring, in this case a leaf spring, when the pressure of the balls ceases when the chain runs out. When the brackets 10 are pushed apart, the coupling * pieces 4 aa the disks 1 are pressed. By using balls, large contact pressures can be achieved with a small chain pull.

Due to the special design of the recesses U in the pans it is achieved that the coupling element 4 after the inlet into the discs through the Badialkompoaeate of the chain suction «Are unequally pressed, but then by the essential stronger chain hoist itself must be pressed even more tightly.

So that no lubricating film can form between the panes 1 and the coupling pieces and thus a great look! arises from support points, the height of the coupling pieces 4 or the surface of the washers 1 or the surfaces of both should be divided into elements that are as small as possible.
