the type of the worm:Archimedes
start of it:one
axial module:2..5
L=1.6m
meaterial:20CrMnTi<worm shaft and screw>copper<worm gear>
worm:
Can be a lot of drive ratio than the body staggered compact helical gear
Two rounds of mating tooth surface for line contact, the bearing capacity much higher than the cross-axis helical gear body
The equivalent of worm drive screw drive for multi-tooth meshing transmission, the smooth transmission, low noise
With self-locking nature. When the worm lead angle is less than the gear meshing between the equivalent friction angle, the body has self-locking and reverse self-locking can be achieved, that is, the worm can only be driven by the worm, and not driven by the worm gear worm. Such as in its use of heavy machinery of the self-locking worm and its reverse can be self-locking security protection from the role of
Lower transmission efficiency, more serious wear and tear. Meshing worm transmission, the meshing teeth relative sliding velocity, and therefore large friction loss, low efficiency
