Engaging the gear unit

☞ Push the adjusting unit, consisting for example of the gear unit and two lateral angle

irons, manually into the gearing until the pinion meshes with only little backlash with the

rack. Then slightly fix the adjusting unit with the screws. Move it over the length of the

travelling path and seek the high point. When the pinion is properly engaged in the rack

the adjusting unit can be fixed permanently; if not, it must be readjusted. At the low point

of the traverse there will be a play of the tooth flanks the size of which depends upon

the quality of rack and pinion. Depending upon the quality of the rack the circumferential

backlash can vary more or less.

Do not mount the pinion to the rack under tension so as to produce

freedom from backlash. This would lead to the failure of the gearing

due to wear and tear or rupture of teeth.
