This is description of this part:
Steel gear wheel (pinion gear) for the coarse and fine focus of Carl Zeiss Axiolab microscopes.
This is a gear wheel joined to a coaxial pinion. The large gear wheel transfers the movement from the shaft that the user turns with the knobs - and on the smaller pinion runs the brass toothed rack (https://www.microscopeparts.eu/part/99943), raising and lowering the stage with the specimen.
In the Zeiss Axiolab microscope these wheels are mounted on the housing casting on a relatively thin axle (it is included in the set offered here), and even the slightest bend of that axle makes the gear turn unevenly.
This gear wheel was removed from a Zeiss Axiolab re microscope, P/N 45 09 05 (also written as 450905). However, it also fits the following variants:
- Zeiss Axiolab drb KT, which carries the same number 45 09 05 (450905)
- Zeiss Axiolab E re, 45 09 07 (450907)
- Zeiss Axiolab A, 45 09 09 (450909)
- Zeiss Axiolab Pol, 45 09 10 (450910)
I was not able to confirm this, but in my opinion it is very likely that the focusing gear wheel from the Zeiss Axiolab microscope also fits the following microscopes:
- Zeiss Standard 20
- Zeiss Standard 25 ICS
- Zeiss Axiostar
- Zeiss Axioskop 20
It may also fit the inverted microscope Zeiss Axiovert 25.
What is this part needed for?
- as a service part, if you need to replace a damaged gear wheel
