Self-locking capacity
The self-locking capacity is influenced by the lead angle, the
surface structure of the flanks, the sliding speed, the lubricant
and the heating.
For worm gears with centre distance a=100mm and 125mm:
Up to ratio 39:1 not self-locking.
From ratio 62:1 Static self-locking.
Shocks or vibration can override the self-locking capacity. Apart
from that, various factors in connection with lubrication, gliding
speed and load can create such favourable operating conditions
that the self-locking capacity is negatively influenced.
For this reason we cannot grant any guarantee regarding the
self-locking capacity.
