The parent key field name is set to 'uid_foreign' by the DataMapFactory. 
So, no chance to alter that atm (will be possible in the future). But 
can try to map the field 'unternehmen_nr' (assuming that the field 
values are unique) to the property 'uid' by the following TypoScript 
Settings

config.tx_extbase.persistence.classes.Tx_xx_Domain_Model_Unternehmen.mapping.columns.unternehmen_nr.mapOnProperty 
= uid

And to your model (not really necessary):

public function setUnternehmerNr($unternehmerNr) {
	$this->uid = $unternehmerNr;
}

public function getUnternehmerNr() {
	return $this->uid;
}

It's not proven but should work.
