Abstract
A low-voltage power switch, includes a drive device, fixed by way of a supporting framework and an associated switch shaft, fixed by way of two axially external bearing sub-assemblies, to the switch pole sub-assembly. In order to ensure that the fitting corresponds to a position based on separate examination of the drive device, the bearing arrangement has an additional, axially central bearing sub-assembly. The bearing sub-assembly includes two half-shells which are axially fixed by way of guide surfaces, whereby one is radially supported on the switch pole sub-assembly and the other is radially supported on the supporting framework of the drive device.
Claims18
A low-voltage circuit breaker, comprising:
- a switching pole assembly, adapted to hold at least one contact arrangement;
- a supporting mechanism, adapted to hold a drive apparatus,
- a switching shaft, adapted to transmit a drive force from the drive apparatus to the contact arrangements, and
- a bearing arrangement for the switching shaft,
- including at least two axially outer bearing assemblies and one axially central bearing assembly, wherein
- the switching shaft is mounted on the switching pole assembly by the two axially outer bearing assemblies, and wherein
- upon the supporting mechanism being mounted on the switching pole assembly, the axially central bearing assembly includes two bearing half shells, one supported radially on the switching pole assembly and the other supported radially on the supporting mechanism, and is fixed axially via guide surfaces.
A low-voltage circuit breaker, comprising:
- a first assembly, adapted to hold at least one contact arrangement;
- a mechanism, adapted to hold a drive apparatus,
- a shaft, adapted to transmit a drive force from the drive apparatus to the contact arrangement;
- and
- a bearing arrangement, including at least two axially outer bearing assemblies and one axially central bearing assembly, wherein the shaft is mounted on the first assembly by the two axially outer bearing assemblies, and wherein, upon the mechanism being mounted on the first assembly, the axially central bearing assembly includes two bearing half shells, one supported radially on the first assembly and the other supported radially on the mechanism.
A low-voltage circuit breaker, comprising:
- first means for holding at least one contact arrangement;
- second means for holding a drive apparatus,
- means for transmitting a drive force from the drive apparatus to the contact arrangement;
- and
- a bearing arrangement, including at least two axially outer bearing assemblies and one axially central bearing assembly, wherein the transmitting means is mounted on the first means by the two axially outer bearing assemblies, and wherein, upon the second means being mounted on the first means, the axially central bearing assembly includes two bearing half shells, one supported radially on the first means and the other supported radially on the second means.
