Abstract
The invention relates to a tangential thread rolling head including two rolling head arms having a thread roll rotatably mounted on an axle. The thread rolls are configured to engage with a gear and be pushed laterally into an assembled position into the rolling head arms before the installation of the axles and the axles can be pushed into a bearing bore hole of the thread rolls. The two thread rolls have identical thread profiles that are offset with respect to each other when the thread rolls are in the assembled position.
Claims9
A tangential thread rolling head comprising:
- two thread roll arms;
- two thread rolls having identical circumferentially disposed thread profiles, each thread roll defining a bearing bore hole and configured to be rotatably mounted on an axle, wherein each thread roll engages a gear coupling the thread roll and can be pushed laterally into an assembled position into the rolling head arms before installation of the axle, and wherein one of the axles can be pushed into the bearing bore hole of a thread roll;
- and
- a roll engagement means configured to engage a gear engagement means of the gear, the roll engagement means and the gear engagement means configured to only allow the two thread rolls to be installed in a single defined rotary position, wherein the single defined rotary position of the two thread rolls offsets the identical circumferentially disposed thread profiles with respect to each other.
