helix angle (for b >23° left helix is used for technological reasons)
number of flights
Worm gear reducers are often non-reversible. The driven machine is then not able to drive the input
shaft back through the output shaft. The non-reversibility depends on the efficiency and the helix angle.
It therefore happens at the higher transmission ratios. The above table shows the important
parameters: module mn, the helix angle b , and the number of flights z1.
Static non-reversibility
The worm gear reducer cannot be reversed if
stationary. This non-reversibility can still be overcome
by shocks or vibrations.
Dynamic non-reversibility
Dynamic non-reversibility causes the gear reducer
output shaft to stop when the input shaft stops
revolving. This non-reversibility depends on the
reducer’s size, its efficiency, its transmission ratio,
precision of the gear machining, the lubricant used
and the input speed. If non-reversibility is to be
guaranteed use of a brake motor is recommended.
