Embodiment Construction

[0014] figure 1 A pressing device according to the invention for connecting an energy store is shown in a schematic side view. The device comprises a pressing shaft 1 with an eccentric 3 arranged at its first end 2 . At the second end 4 of the pressure shaft 1 , a cam 5 is fixedly connected to the pressure shaft 1 . The cam 5 is operatively connected in the circuit breaker to a switch shaft, not shown, in order to transfer the energy stored in the making accumulator to close the movable contacts of the circuit breaker. On the housing part 6 of the pressing device, in which the pressing shaft 1 is rotatably mounted by means of ball bearings 6a, 6b, a fixed stop element 7 is provided. A drive lever 8 is fixedly connected to the pressing shaft 1 , which interacts with a drive wheel 10 via a pawl 9 . The pawl 9 is here rotatably arranged on the drive wheel 10 by means of a spring element 11 . The drive wheel 10 is the last drive wheel of a transmission not shown, for example a...

Abstract

In order to form a tensioning apparatus for a switch-on energy store of a circuit breaker, in which apparatus a tensioning shaft, which can rotate by means of a drive wheel, for tensioning the switch-on energy store is fixedly connected in each case to a cam and to a cam disc, which apparatus has a tripping stop, in which apparatus the drive wheel is coupled to the tensioning shaft via a clutch, and which apparatus has a simple and at the same time cost-effective design, the invention proposes that the clutch is a ratchet arrangement.

Description

technical field [0001] The invention relates to a pressing device for connecting an accumulator for a circuit breaker, wherein a pressing shaft rotatable by means of a drive wheel is fixedly connected to an eccentric wheel and a cam respectively for pressing the connecting energy accumulator , and the cam has a trigger stop, and in the pressing device, the drive wheel is connected with the pressing shaft through a coupling. Background technique [0002] Such a pressing device is known from DE 199 33 637 C1. In such a pressing device, the spur gear as the drive wheel is separated by a disconnectable coupling after the pressing of the switching spring as the switching energy store. The separation or decoupling allows the spur gear as a spur gear of the transmission and thus the transmission to continue to run or to rotate without increasing the pressure, for example due to incorrect operation. Or the wear of the transmission mechanism. Here, the disconnectable coupling cons...
