Hollow Flank Worm Gear Sets(ZC-Worm Gear Sets)

GEARX brand hollow flank worm gear sets(ZC-worm gear sets) are machined with the unique gear tooth geometry, it is called hollow-flank profile(tooth form C). compared with the normal cylindrical worms and worm gears, under the same size, the hollow flank worm gear sets(ZC-worm gear sets) are far superior to comparable gear sets, with this pairing of the gear teeth, the hollow flank worm gear set can ensures an extremely low specific gear flank pressure. As the hollow flank worm profile teeth are subject to only low specific tooth pressure and give a better lubrication oil film between the tooth flanks, so the profile contact is much more favorable than in conventional gear teeth systems.

Hollow flank worm (ZC-worm) is also called ZH worm in Germany.
