4 INSTALLATION ON THE MACHINE
WARNING! HANDLING OPERATIONS.
Never handle the DRP+ unit with bevel gearbox shafts. Use lifting rings fixed in the universal
housing or in the pinions.
4.1 Rack mounting tolerance
Parallelism between the rack reference surface and the linear guide
The DRP+ requires that the rack has been installed on the machine following the rack manufacturer
mounting procedure and respects the tolerances shown below:
We advice to measure the parallelism error values on 3 points for each segment of rack, as shown on the
drawing below. This rack topography will be used for proper tooth meshing validation and preload
setting (see next chapters).
In order to control the pitch error, we also recommend doing 3 measurements at each connection of 2
rack segments, as shown on the sketch below.
The variation between the 3 comparators at each connection must not exceed:
- 0.015 mm for a rack module 3,
- 0.020mm for a rack module > 3.
