Hand Wheel Worm Gear Screw Jack - Chinaprice: contact company for price
solutions for applications where electricity
or power generators is inconvenient or
dangerous, light weight, low duty cycle, low
target cost and short travel length.
hand wheel worm gear screw jack is composed
of hand wheel or hand crank and a complete
set worm gear screw jack with internal worm
and worm gear sets, standard hand wheel or
hand crank dimensions from 5" to 20"
diameter, special hand wheel or hand crank
dimensions required, please contact Jacton
engineers. When hand operated worm gear acme
screw jack, machine screw jack, which has
intermittent precisely positioning and self-
locking feature for no creeping down without
brake mechanism or other locking systems. But
hand operated worm gear ball screw jack, no
self-locking feature, avoid ball screw back
drive with attached load, which needs
additional brake or locking mechanism to
prevent it creep.
All hand wheel worm gear screw jack has this
disadvantage, slow travel speed, maximum
1.5mm travel length per full turn of hand
wheel or hand crank. Hand operated bevel gear
jack is ideal solution of slow travel speed
with internal pairs spiral bevel gears,
maximum up to 12mm travel length per full
turn of hand wheel or hand crank.
For precise position display, a range of
digital mechanical counters are available for
matching with hand operated screw jacks.
These digital mechanical counters measure the
rotations of the input shaft and display
corresponding position in a mecahncial
counter window. The display value per input
shaft revolution is variable and is achieved
through a series of gear reductions
configured to accommodate different worm gear
screw jack ratios, screw pitch and travel
