Product Description:
A handwheel is a convenient solution for manually operating a jack or jack systems when using worm gear
screw jacks in intermittent positioning applications. Handwheels are available in a range of diameters from 5 to 12 inches and can be adapted for use on jacks following customers' need.
For precise position display, a range of digital counters are available for use with Worm Gear Screw Jacks. These digital counters measure the rotation of the input shaft and display corresponding position in a counter window. The display value per input shaft revolution is variable and is achieved through a series of gear reductions configured to accommodate different jack ratios, lifting screw pitch and travel distances.
Manual operation power formula:
* f=w*p / r1*r2
F: hand force (kgs)
W: working load (kgs), 1 KN = 102 kgs
P: acme screw pitch (mm)
R1: reduce speed ratio
R2: handle radius (mm)
For example: RN-100T, pitch 16 mm, speed ratio 1:32, working load 50000kgs, handle radius 500 mm. F = 50000*16 / 32*500 = 50 kgs
* Rotation power of Hand wheel = Input Torque / Diameter of Hand Wheel
